I want to make my own multi-wire chamber for school, and I wonder what kind of effect different wires will have on the efficiency. After reading many papers containing research for wire chambers, I saw that all of them did tests with wires made of gold plated tungsten wires with a diameter of...

I don't have any solution

In 1992, Suffolk-resident Eric Lawes and retired farmer, went looking for a missing/misplaced hammer. https://www.thevintagenews.com/2019/04/16/hoxne-hoard/ Lawes discovered what became known as the Hoxne Hoard, "close to 60 pounds of items made from silver and gold were found on the site...

From a Science mag news article. It can also affect non-domestic cats: Apparently, nepetalactone is known to have mosquito repellent properties (similar to DEET). Not that surprising if its supposed to protect the plants from aphids.

After reading the Jetman has died from accident using the jet. Vince Reffet, 'Jetman' pilot, dies in training accident in Dubai - CNN I watched Silver Surfer movie thinking a portable flying device based on gravitation nullifying material is safer. But it is difficult to balance on the silver...

That's it, just the question. I am figuring that the tarnish is an irrelevance as it does not participate either magnetically or electrically, so any RF current passing through the [still metallic] silver top layer, albeit with tarnish over the top, will pass through the same thickness of...

I'm curious what weak acids will form soluble salts with aluminum, but not silver. From a solubility chart (https://www.flinnsci.com/globalassets/flinn-scientific/all-product-images-rgb-jpegs/ap6901etc.jpg?v=cc7f986a028e4adf833ea6341200add2), HCl, HBr, and HI will form soluble aluminum salts...

Hume–Rothery rules seem to be moderately satisfied for nickel to readily dissolve in silver. Silver has a radius of 144, valence of 1 and an electronegativity of 1.93. Nickel has a radius of 124, valence of 2 and an electronegativity of 1.91. Both elements have a fcc crystal structure. I read...

Not attempt

Hi, A straight question here, no complicated quantum theory equations for this, I just want to know a piece of data. What is the saturation flux of silver steel? It has a fraction of a percent of chromium in it, so was wondering if it was less than carbon steel's ~1.6T?

A little background on my experiment … "Henna" (Lawsonia plant hair dye going way back to ancient times) used to be combined with metallic salts to cause it to adhere to the hair and make it thicker with cumulative use. In foreign countries "compound henna" is still being sold but often w/...

Would using mercury to form amalgam alloys combining gold, copper, and silver have any electronic value? Has this amalgam ever been made and tested in conductivity and Malleability? Or would it just be an expensive filling?

I remember reading on a blog or a news article on the internet once that sometimes counterfeiters have made fake silver coins and silver bars out of molybdenum. Silver is worth far more than molybdenum. Counterfeiters made fake silver out of molybdenum because they could acquire the molybdenum...

The Silver Surfer can transmute molecules as when he passes thru a subway train in part 1 or part 2 and he can transform into pure energy. Silver Surfer serves Galactus and destroys planets and let Galactus use it as sustainance. Supposed Silver Surfer would use his power to separate the...

does anyone know where to buy ultra thin (0.024" or less) large silver and gold foil squares (like 7"'x7" for gold/silver and up to 3'x6' for silver)? Looking into large and small sputtering and sealing around a large surface area of metal and connecting the electrode outside the vacuum is...

What is the solubility of silver salt of the formula RCOOAg (RCOO=phenylbutyrate, DMF, MeOH, water?)

Hi, I'm hoping someone out there can help me. I've vented my system to clean her out this week and as I was checking my targets I noticed that the whole sputtering surface of my silver target was white. I've been able to clean the white layer off but have no idea what it is or how it happened...

Hi all,If there is activation energy for chemisorption, then an atom with insufficient energy to overcome that barrier will remain physisorbed to the surface via van der Waals forces. I would like to further understand this activation energy in terms of, for example, the overlap of electron...

I have a piece of equipment that was manufactured using direct metal laser sintering made of a titanium alloy (Ti-6Al-4V). It is a cylinder with thin helical channels that is located above a vapour source in vacuum. I plan to coat it with silver, and I am looking for an effective way to...

Hi all, I'm new to this forum and I'm wondering which calculator I should get. I'm planning on taking the ACT so I can't get (use) a Ti-89 titanium or a Ti-nspire CX CAS. I'll taking AP Chemistry, AP Calculus, AP Statistics, AP Biology, AP Physics, and AP Computer Science. Thank You!

Copper ::: 60.7 x 106 S m^-1 Silver :::62.9 x 106 S m^-1 Gold :: 48.8 x 106 S m^-1 Why is the electrical Conductivity of these elements this way? I mean down the periodic table it should increase in case of GOLD but instead Gold is have far less value of Electrical Conductivity.

More specifically, the free electron density in increasing order goes like this: Ag Cu Al why then is the conductivity in the reverse order? ie the free electron density doesn't seem to play much of a role in conductivity beyond a certain point.

The question is, which anion could be used to selectively remove silver ions from solution? The options are Cl, SO4, or CO3. All 3 of them form precipitates, but is there any that is better than the others?

According to electrochemical series ,gold is the last element thus it is depicted that it is the best electrical conductor.(most of the teachers say that) But according to the internet the best electrical conductor is silver , following copper and gold. Which one is true and why ?

Would a silver suite be a better body temperature decreaser than a mister of water? I cool myself off by spraying myself with water but I hear silver is the best conductor, is it better at conducting heat off my body than mist?

I'm going to attempt the Mohr's Method chloride test at home for my saltwater aquarium. It requires me to add 5g of sliver nitrate to 250ml of distilled water and store it in a brown bottle. I have an opaque, black 750ml bottle I can use that I washed out with 0 TDS water. It used to contain...

So based on String theory, when doing a Double Slit Style Experiment when an observation is made it is a particle and when on observation is not made, it is a wave pattern. What exactly do the Interference patterns mean? Basically what I research was this... Doe it means that in the...

One of my first solubility lessons regarded the great ability of the acetate ion to form a water-soluble salt with any other cation. One of my most recent lessons regarded the great ability of the silver(I) ion to override the previous rule. Why is silver the only ion that makes a...

Homework Statement For a silver atom, energy corresponding to Kα transition is 21.75 KeV. Also minimum energy of a striking electron so as to produce L X-Rays is 3.56 keV. Now, if electron with an energy of 23 keV strike a silver target the characteristic X-rays spectrum will have a)only kα...

This is my last question on a prefab and I want to make sure this answer is correct. The question states; On the basis of LeChatelier's principal, explain why silver carbonate dissolves when nitric acid is added. I said it was because mixing nitric acid and silver carbonate will produce...

We go through an inordinate amount of fix in our photo labs (20+ gallons/week) and are interested in trying to recover the silver. An electrolytic cell seems like the way to go. Anyone have suggestions, tips, or advice in general?

If I was to electrolyse a hot sodium chloride solution I'm pretty sure a copper electrode would react to make copper chloride. Whereas I would have used graphite electrodes if the solution was cold, this reaction should produce sodium chlorate which can obviously be quite reactive with organic...

Homework Statement Lets say we have a silver ball with radius ##r=1cm## hanging on a string which is an isolator. What is a charge on the ball if we shine on it with a light with ##\lambda = 200nm##? The work function for silver is ##A_0 = 4.7eV##.Homework Equations \begin{align} &W - A_0 = W_k...

As a science teacher, I also had the unfortunate experience of getting silver nitrate on my hands. As you know, it stains a horrible brown/black colour and is difficult to remove. I would just like to share with my fellow scientists what doesn't work: 1.) Washing your hands with water, no...

I am not an engineer so I was wondering if a pound of gold can ever weigh more than a pound of silver under any circumstances relative to the universe as a whole? John

Hi I'm new to the forum, so first I want to say hello to everyone. I have been interested in Colloidal Silver lately, and I have produced it with electrolysis in distilled water with NaCl as an electrolyte. I have used a Silver electrode and cathode for both of these experiments. I...

Hi everyone. I have been presented with a problem- to produce a set amount of pure, dry oxygen in any way I can, provided it is safe and accessible. I have chosen to tackle the problem by heating silver oxide until the silver and oxygen separate, however there remains the problem of isolating...

What's stopping entrepreneurs from using fission - taking mercury, for example, or any heavier element for gold/silver - and creating gold and silver from it? Do you think there will come a day when this is commercially viable? Any guesses when?
