Warning Signs That You're Zinc Deficient
 
05:53
For more info: https://draxe.com/zinc-deficiency/?utm_campaign=Youtube-Feb-2015&utm_medium=social&utm_source=youtube&utm_term=zincdeficient Today I’m going to share with you the five warning signs that you’re zinc deficient. About 75% of people in the world are deficient, so being deficient in zinc is very common. The 5 warning signs you’re zinc deficient: 1.) If you get sick a lot or have immune system issues 2.) Have leaky gut (http://draxe.com/7-signs-symptoms-you-have-leaky-gut/) 3.) If you struggle with diarrhea or IBS 4.) Thinning hair 5.) Inflammatory skin issues like acne, eczema, dermatitis, psoriasis One of the biggest factors in causing zinc deficiency is high levels of emotional stress. The second most common cause of zinc deficiency is over-exercise. The third most common reason your zinc deficient is if you’re pregnant or breast feeding. Lastly, if you’re older, you may tend to have malabsorption, which causes a zinc deficiency. In order to get more zinc in your diet, you need to consume more zinc-rich foods. The top 5 zinc-rich foods are pumpkin seeds, oysters, grass-fed beef, sprouted nuts and seeds, and peas. Additionally, probiotics are a key supplement to take when zinc deficient because it can help your overall absorption of nutrients.

Making Transparent Metal? Invisible Sodium chemical experiment!
 
07:26
Please note that this video was made solely for research and demonstration purposes! Do not attempt to repeat the experiments shown in this video!Hello everyone! Today I will show you a very unusual effect, that I observed in the reaction of sodium with water on the surface of wet napkins.As we already know from my previous videos, sodium is an active alkali metal. It is quite soft and vigorously reacts with water. If you just throw a piece of sodium in the water, usually it melts first, then lights up and then explodes. However, if you perform the reaction of sodium with water under different conditions, we can observe a very unusual effect. Take a cup of water and put a filter paper on it’s surface. Next, take a medium size piece of sodium, and put it on the wet surface of the filter.When sodium metal contacts with the wet filter surface, the reaction begins. As a result of the heat during the reaction, sodium eventually melts and then ignites. But after this an unusual effect takes place which I still cannot explain.Burning stops, and a droplet of sodium that was just black becomes red and then transparent. After that the droplet begins to float on the water surface and in the end it explodes. I did this experiment several times and every time the same result has been achieved. First, the droplet of sodium ignites. Then, the burning stops. And then, for reasons unknown to me, a droplet of unknown substance was formed which was floating on the surface of water. Whether, we are dealing with a transparent sodium, or any other substance was formed, such as sodium hydroxide, or a sodium hydroxide mixture with water in unknown proportions? Why the droplet becomes perfectly clear? Still I cannot find the answer to this question. If we assume that we are dealing with sodium hydroxide, then why this droplet doesn’t sink and instead floats on the surface of water? As the density of sodium hydroxide is 2 times greater than the density of water. Or can we assume that we are dealing with undiscovered properties of sodium metal, which is to acquire a transparent state under certain conditions? I began to study this question. I have started looking for scientific articles which mention the transparent state of sodium metal. Luckily I found something. However, in this article written by Russian and Japanese scientists, the transparent state of sodium was only described having a very high pressure, more than million atmospheres. With huge pressure sodium droplet becomes transparent. I wrote to the authors of this article about the effect that I was able to photograph. Authors answered that we could be dealing with a transparent sodium hydroxide. But the question remains, why did this drop float and didn’t not sink? Perhaps because of the temperature difference between the droplet and water, we have to be dealing with the Leidenfrost effect, which we can observe by pouring liquid nitrogen on hand. I even spoke to Professor Toomas Tamm at Tallinn University, who is working in inorganic chemistry field. He suggested that perhaps we are not dealing with a pure sodium metal or sodium hydroxide, instead maybe with some kind of phases that sodium hydroxide can form with water. Thus, due to the special optical properties of this drop, it becomes transparent. I also managed to shoot the behavior of sodium on the surface of wet filter. Thus, we can clearly observe spheroidal state which the burning sodium droplet acquires after becoming transparent. Nevertheless, I have not received a clear answer to this question, and the effect that I was able to observe. Perhaps you, the viewers of my channel, could help me find an explanation for this effect. Why the sodium droplet becomes transparent after burning? What happens in this reaction? Write in comments your assumptions, and maybe together we will be able to find an explanation to the effect that we were able to observe. For those of you who were not very interested to listen to a scientific chatter, I suggest you to take a look at the moments in which the reaction of sodium and water was going out of control. Happy viewing! And those of you who were interested in the scientific side of this video, I propose to discuss such an effect that we were able to observe in the comments. Thanks for watching!

Best Penetrating Oil Test for Rust, Spark Plugs - ATF & ACETONE - Kroil - Bundys Garage
 
06:56
ATF and Acetone tested on a rusty screw, bolt, see what the results were of the Test. This 50/50 mix is the most effective, inexpensive, cheapest penetrating oil you can make at home. A homebrew to break rusty bolts loose. I didn't believe it until I did this test of Acetone and Automatic Transmission Fluid. I'm sold, I will never go buy expensive penetrating oils again. You can use this to break rust loose, free up spark plugs, for rust and it is also a great alternative to Kroil.

Antipsychotics for schizophrenia are not very effective, Peter Gotzsche, MD
 
01:11
Hi, this is Larry Hobbs @ FatNews.com. http://fatnews.com/ https://twitter.com/fatnews Antipsychotic drugs used for schizophrenia are not very effective notes Prof. Peter Gotzsche, MD Antipsychotic drugs used for schizophrenia have very little effect on improving the disease notes Prof. Peter Gøtzsche, MD. These drugs effect on improving symptoms of the disease when measured on a scale used for schizophrenia (the PANSS) was only 6, when the difference that is considered minimally clinically relevant is 15. Dr. Gøtzsche writes: “Trials in schizophrenia [drugs] are also disappointing. “In newer submissions to the FDA, the effect on the positive and negative syndrome scale (PANSS) was only 6 even though these trials were heavily biased by cold turkey and unblinding effects. “This is far below the minimally clinically relevant effect, which is about 15.” About Dr. Gøtzsche Dr. Gøtzsche is the author of several wonderful books including Deadly Psychiatry and Organised Denial in which he talks about the problems with psychiatric drugs. He is also author of the wonderful book Deadly Medicines and Organised Crime: How Big Pharma Has Corrupted Healthcare. Dr. Gøtzsche also cofounded the Cochrane Collaboration in 1993, which is a group of scientists around the world who analyze data to try and figure out the truth about drugs and other health topics.

Make Sodium Silicate (AKA "Water Glass") from Cat Litter and Drain Opener (fixed)
 
07:28
(Fixed to be more informative for particular ratios) In this video we use cat litter and drain opener to make sodium silicate. This will be a valuable precursor to other silicon based chemicals in the future. Most cat litter is made from clay but "crystal" cat litter or "silica" cat litter is made from silica gel. Silica gel is amorphous silicon dioxide made by aqueous chemistry is very easy to convert into other silicon compounds. The process is quite straightforward: 60g of silica gel based cat litter is mixed with 100mL of water. Then 80g of sodium hydroxide is slowly added to dissolve the silica gel. What's produced is a solution of sodium silicate. Donate to NurdRage!

6. Seeing Bonds by Electron Difference Density
 
51:10
Freshman Organic Chemistry (CHEM 125) Professor McBride uses a hexagonal "benzene" pattern and Franklin's X-ray pattern of DNA, to continue his discussion of X-ray crystallography by explaining how a diffraction pattern in "reciprocal space" relates to the distribution of electrons in molecules and to the repetition of molecules in a crystal lattice. He then uses electron difference density mapping to reveal bonds, and unshared electron pairs, and their shape, and to show that they are only one-twentieth as dense as would be expected for Lewis shared pairs. Anomalous difference density in the carbon-fluorine bond raises the course's second great question, "Compared to what?" 00:00 - Chapter 1.

Make Sodium Silicate
 
01:50
We make sodium silicate from drain cleaner and those little gel beads you find packaged with electronic items for humidity control. The procedure is really simple, just make a solution of 10mL with 4-8grams of sodium hydroxide, use the full 8 grams if you want stoichiometric sodium silicate, and 4 grams if you want "liquid glass" solution for doing the chemical garden experiments. Heat the solution and add in 6 grams worth of crushed silica gel beads. The finer the better. if they aren't dissolving, you might need to add more water. Once it's dissolved, you'll have a concentrated solution of sodium silicate. For experiments using Sodium Silicate solution, check out these videos: http://www.youtube.com/watch?v=a45jZOc7PRY

Make Glass Mirrors with Silver Nitrate
 
02:26
How to make a mirror silvering solution from silver nitrate, ammonia, sugar and sodium hydroxide. Glass surfaces can be given coatings of silver that make them into mirrors. WARNING: Perform the whole experiment in less than two hours. This is because the solution generates extremely dangerous/explosive silver nitride on standing. Also, the solution will give off ammonia when heated so you'll need to do this outside, in a fume hood or in a well-ventilated area. And wash away all chemicals with lots of water. To do this, you first need the silver nitrate we made in a previous video: http://www.youtube.com/watch?v=d6hPgGV_qAg Get one gram of silver nitrate and one gram of sodium hydroxide. Then add enough water to both to completely dissolve them. Mix them together and you'll get a black precipitate of silver oxide. Then add enough ammonia to completely dissolve the silver oxide. Add four grams of sugar and mix well. The solution will deposit silver coatings when its heated. If you heat it in a glass container it will deposit silver on the inside of the container. To deposit it onto a glass pane you can put the glass into a tray with solution and heat the tray from below. But do not let the solution boil. Boiling tears the silver off the surface. Thin layers of silver can be wiped off with a cloth if the silver goes where you don't want it. Thicker layers can be removed by applying hydrochloric acid. This process produces a back reflective mirror, which is what most household mirrors are. For more information on the chemistry: Google "Tollens Reagent". This reaction is used in chemistry to test for aldehyde groups. Thanks for watching! Plz subscribe, rate and comment!

Drug studies exaggerate benefits of psychiatric drugs, Peter Gotzsche, MD
 
02:06
Hi, this is Larry Hobbs @ FatNews.com. http://fatnews.com/ https://twitter.com/fatnews Psychiatric drug studies exaggerate benefits of these drugs by study design says Peter Gotzsche, MD “The randomised trials [of psychiatric drugs] that have been conducted do not properly evaluate the drugs’ effects,” writes Prof. Peter Gøtzsche, MD. “Almost all of them are biased because they included patients already taking another psychiatric drug. “Patients, who after a short wash-out period are randomised to placebo, go “cold turkey” and often experience withdrawal symptoms. “This design exaggerates the benefits of treatment and increases the harms in the placebo group, and it has driven patients taking placebo to suicide in trials in schizophrenia. Dr. Gøtzsche is the author of several wonderful books including Deadly Psychiatry and Organised Denial in which he talks about the problems with psychiatric drugs.

Ghost Metal (Chemistry Trick) - Version 2
 
03:27
In a variation of luminol chemiluminescence, we make a coin appear to glow with ghostly trails. This is an improved version of the original video in 2011 Get 100mg of luminol and dissolve it in 100 mL of 5% ammonia solution, the exact concentration isn't critical. Then add 300 mg of disodium EDTA. Add 10 mL of 3% hydrogen peroxide and dilute the whole solution into 900 mL of distilled water. Get a piece of copper metal, a penny will do, and drop it in with the lights out. The penny will start to glow as the surface dissolves to form a copper amine complex. The complex catalyzes the reaction of hydrogen peroxide on luminol and causes the solution near the coin to glow. Bright trails can be seen if the copper is moved. The EDTA will prevent the whole solution from glowing and restrict the reaction to just near the metal. This was a big problem in the original solution. A fortunate side effect is that the useful lifetime of the solution extends out to half an hour rather than just a few minutes. A fun trick to do is to bend wire words and dip them into solution.

Silica Gel in Water
 
06:31
Ever find those little white packets that say "throw away" and "Do Not Eat"? They are silica gel beads and they absorb like 60% of their mass in water. But, When they are dropped in water, they tend to absorb too much water. This causes them to "Crack" like ice sometimes does when you put it in a glass of water. Believe it or not but these "Gels" are used in making glass. You might have heard of the Chemical, Silicon Dioxide or SiO2. This is what these gels are.

Make Copper Sulfate from Copper and Sulfuric acid (3 ways)
 
04:01
We make copper sulfate from copper and sulfuric acid using two chemical methods and one electrochemical method. Copper does not directly react with sulfuric acid so some form of oxidant is needed. Hydrogen peroxide and nitric acid are excellent oxidants and the first two methods demonstrate this. The nitric acid method however produces toxic nitrogen dioxide gas so you'll need to perform this one outside or in a fumehood. Because both chemical methods are rather expensive. A very cheap electrochemical method can be performed by running a current through two copper electrodes immersed in sulfuric acid. The copper is converted to copper ions at the positive electrode and hydrogen gas is formed at the negative electrode. However if the electrodes are placed side by side then the copper ions will diffuse to the negative electrode and get converted back into copper. This is wasteful as you've used power to accomplish nothing. So the better way is to separate both by gravity with the positive electrode at the bottom. The denser solution of copper sulfate will remain near the bottom and thus increase efficiency. As a side note, the electrochemical method is actually very expensive if you use batteries as your power source. The charge on a battery generates a comparatively small quantity of total copper sulfate compared to the same cost of chemicals for the chemical methods. The cheapest way is to use a DC power supply. The cost of municipal electricity is very small compared to the cost of batteries and chemicals.

Grow Silver Metal Crystals by Electrochemistry
 
05:51
In this video we grow crystals of pure silver metal by electochemistry. The procedure is fairly simple. Just apply an electric current between a silver anode and an aluminum or silver metal cathode while they are immersed in silver nitrate solution. The silver ions from the anode will deposit on the cathode. The crystals are microscopic so to see them the solution is placed under a microscope. A glass slide may be placed over the solution to keep the surface flat so you can see it better. The crystals grow in different shapes depending on concentration and current applied.

38. Review: Synthesis of Cortisone
 
52:09
Freshman Organic Chemistry II (CHEM 125B) Discoverers of the structure and biological activity of steroid hormones won seven Nobel Prizes between 1927 and 1975. Studying the steps involved in Woodward's 1951 "total" synthesis of cortisone provides a review of the organic reactions covered this semester. Many steps involved novel insights, others were based on lore from previous work In the area. The overall yield of such sequential syntheses is typically much lower than that of convergent syntheses. Practical syntheses of cortisone were based on modification of related steroids readily available from nature. Milestones in total synthesis include both purely intellectual work with natural products and commercially important synthesis of designed pharmaceuticals. The course ends with thanks to those, young and old, who have taught us all. 00:00 - Chapter 1. Steroids and the Medicinal Activity of Cortisone 07:43 - Chapter 2.

4th of July 2017 Fireworks Boston
 
19:04
(для текста на русском - пожайлуста, пророллируйте вниз) **** 19 min (out of 20-21 min) of fireworks in Boston on 4th of July, 2017 as seen from Cambridge side not far from Longfellow Bridge - it turned out to be a good vantage point: right distance, right angle (notice how the letters 'U' 'S' 'A' appeared perfectly correctly). Filmed with iPhone6S (alas, sometimes focus is not perfect). Music was not audible there but show was visually good enough... And, at the end, just a little bit of chemistry - which chemicals produce which color... Here it is: copper oxide or cooper chloride - BLUE color (hardest color to produce, requires perfect chemistry); strontium salts (strontium chloride), lithium salts (lithium carbonate) - RED color (for even stronger color they add some magnalium (magnesium-aluminum allow) or use strontium carbonate or strontium nitrate - BRIGHT RED); mixture of strontium (red) and copper (blue) compounds – PURPLE color; strontium oxide - ORANGE-RED color; calcium nitrate (or carbonate, or chloride) - ORANGE color; sodium chloride - YELLOW color; barium acetate (or carbonate) - GREEN color; charcoal, iron, lampback - GOLD color; burning aluminum, titanium, or magnesium - WHITE/SIVER color; adding moderately coarse magnesium produces white sparks effect. ...and so on... **** Фейерверк в Бостоне 4-го июля 2017 - как он был виден со стороны набережной в Кембридже недалеко от моста Лонгфелло - нам всё было видно под правильным углом (когда в небе вспыхивают буквы 'U' 'S' 'A', то это наглядно). Видео снято на iPhone6S (к сожалению, фокус иногда подводит, но быстро исправляется). И ещё - немного химии, поскольку всегда было интересно понять откуда берутся разные цвета фейерверка. СИНИЙ цвет - самый трудный цвет в фейерверках, поскольку синий цвет легко забивается любым другим и требует идеальной химии и идеальной чистоты реактивов. Оксид и хлорид меди производят синий цвет. При этом хлорид меди (I) CuCl даёт бирюзовый цвет. Основной карбонат меди (Cu2(CO3)(OH)2) имеет цвет от светло-голубого до ярко-голубого. Однако все они не делают цвет таким насыщенным как ацетоарсенит меди (Cu3As2O3Cu(C2H3O2)2). ЯРКО-КРАСНЫЙ цвет дают след. соли стронция: карбонат SrCO3, нитрат Sr(NО3)2 или оксалат SrС2О4 стронция. Хлорид стронция и карбонат лития Li2CO3 дают КРАСНЫЙ цвет небольшой интенсивности (для большей интенсивности цвета доб. ещё и сплав магния с алюминием). Окись стронция SrO окрашивает пламя лишь в РОЗОВЫЙ цвет (иногда дают красно-оранжевый цвет). Излучение монохлорида стронция SrCl интенсивнее и ярче излучения SrO. БРЕДНО-РОЗОВЫЙ цвет дают углекислый кальций (карбонат кальция, calcium carbonate) CaCO3, сульфат кальция CaSO4, щавелевокислый кальций (оксалат кальция, сalcium oxalate) CaC2O4. Для ФИОЛЕТОВОГО цвета смешивают соли меди (синий) и стронция (красный). Нитрат, карбонат или хлорид кальция производят ОРАНЖЕВЫЙ цвет. Хлорид натрия, нитрат натрия (натриевая селитра) NaNO3, криолит Na3AlF6 - ЖЁЛТЫЙ цвет. Ацетат или карбонат бария - ЗЕЛЁНЫЙ цвет; хлористый барий BaCl+ = ярко-зеленый цвет. Искристый ЗОЛОТОЙ - железная окалина (с углеродом), древесный уголь или сажа. Электрический БЕЛЫЙ - стружка или порошок раскаленного металла, такого как магний или аллюминий окись бария, BaO. СЕРЕБРИСТЫЙ цвет - это горение порошка (стружки) аллюминия, титана (образует искры) или магния. Добавление умеренно крупного магния производит эффект белых искр. Цинк применяется в некоторых смесях для образования дыма и эффекта звёзд. И т.д и т.д.... А вот несколько простых и безопасных (как пишут) пиротехнических опытов, которые можно провести в домашних условиях. Если сдавить корку от апельсина над пламенем свечи, то воспламенятся эфирные масла, содержащиеся в корке, и при горении образуют крошечные вспышки света. А другой опыт - не домашний, а уже дачный: поскольку бананы содержат большое количество калия, то сжигание кожуры банана в костре окрашивает пламя в фиолетовый цвет, который характерен для горения калия. Опыт «ОГНЕННЫЙ» ПОРОШОК: зажечь деревянную щепку или лучинку, потом погасить её пламя, чтобы она продолжала тлеть, и посыпать на тлеющую лучину измельченного калия марганцовокислого (перманганата калия) - везде, куда попадут крупинки перманганата, вспыхнет огонь (перманганат калия способствует горению). (Ещё одна интересная новость о пиротехнике - сейчас ведутся исследования и работы, в частности в военных лабораториях в Мериленде, в направлении сделать фейерверки экологичнее, т.е. когда вместо опасных для здоровья веществ (хлориды явл. канцерогенами) будут использоваться безвредные химич. соединения.)

LiNbO3 and LiTaO3 electro-optic crystals sales@dmphotonics.com There are some particular crystals showing change in refractive indices directly proportional to applied electric field. The phenomenon is called linear electro – optic (EO) effect or Pockels effect. Electrically induced birefringence causes plane polarized light propagating through the crystal to be resolved into two orthogonal vectors with change in retardation between them proportional to the magnitude of electric field (applied voltage). In general case this is described by tensor of EO coefficient and leads to rather complicated expressions. However, in many cases calculations are simplified due to crystal symmetry and special configurations between electric field and light propagation referring to crystal axes. There are two practically useful cases. In longitudinal configuration light beam and electric field are parallel. For example, in the KDP crystal for propagation along Z–axis phase retardation will be defined as Г = pno3r63 E • L /λ, where r63 is appropriate EO coefficient, E – electric field, L – crystal length. Apparently, phase retardation Г is proportional to voltage U = E • L applied to crystal. This is called phase modulation. If we place the crystal between two crossed polarizers, output intensity will obey Malu’s law: I = Io • sin2(Г/2) i.e. output intensity can be modulated by applied voltage and this is called amplitude modulation. Max output intensity is achieved when phase retardation is equal to p (or half–wave). It can be seen that appropriate voltage Up = λ/2no3r63 i.e. is defined only by wavelength and material constants. So Up or half–wave voltage is often used as parameter characterizing the efficiency of material as electro–optic modulator. Longitudinal configuration is particularly useful for modulation of large aperture light beams and it is still widely used for KDP crystal and it’s isomorphs although there are disadvantages related to rather high applied voltages (usually 3 – 10 kV) and technical problems of making transparent electrodes or special ring electrodes for generation of longitudinal electric field. In the transverse configuration electric field is perpendicular to light beam which is achieved by placing electrodes directly on two side faces of crystal. In this case phase retardation depends not only on the applied voltage but also on geometry of crystal. In addition to simple design of electrodes transverse configuration allows to reduce applied voltage by factor d/L, where d is distance between electrodes. So transverse modulation is widely used with LiNbO3, LiTaO3 and some other crystals (BBO, KTP). EO crystal cut , polished , with proper coatings and electrodes, usually mounted in some kind of holder, sometimes with additional polarizing elements ( Glan prism or waveplate ) is usually called Pockels cell by the name of effect. There are many parameters that define final choice of EO crystal for some definite application: transparency range, optical damage threshold, EO coefficients or half–wave voltage, dielectric properties, etc. Crystals of LiNbO3 and LiTaO3 are non-hygroscopic, mechanically and chemically stable and available in large sizes with high internal perfection at moderate cost. These properties, combined with wide transparency range and high EO coefficients lead to wide use of LiNbO3 and LiTaO3 for development of Pockels cells with compact and rugged design for environmental, military, R&D and other applications. Such cells are often used as intra-cavity electro-optic Q-switches.
