Re: How hopper crystals form « Reply #6 on: February 18, 2008, 07:23:49 AM » Quote from: AWK on February 18, 2008, 01:23:02 AM Squares? - do you mean cubes? Bismuth crystals are pretty impressive. As you can see, they are layers of square faces, built on the cubic cry...
All you need to grow alum crystals are alum, hot water, and a container. Choose a clear container so you can watch the crystals grow. While not strictly necessary, it helps having a way to tie and suspend a crystal in the liquid. This helps it keep an ideal shape. A coffee filter o...
Biodiesel is a diesel fuel that is made by reacting vegetable oil (cooking oil) with other common chemicals. Biodiesel may be used in any diesel automotive engine in its pure form or blended with petroleum-based diesel. No modifications are required, and the result is a less-expensive, renewa...
Minerals are crystals that are naturally formed of various elements under intense conditions. In the case of kyawthuite, scientists concluded during their study that the gem primarily contains bismuth (a silvery pinkish metal), antimony (a silvery bluish white metal or metalloid), and tetraoxygen ...
the other half are made by me. Generally speaking he makes the fancy platinum group metals like osmium, iridium, etc, while I make the more common transition metals, like bismuth cylinders, manganese ampoules, etc. I'm in the process of photographing the samples we offer:Click hereto see th...

Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle for them to compete with established photovoltaic technologies. The pho
Wolframite is acomparatively rare mineral, and is normally found usually with cassiterite and associated also with scheelite, bismuth, quartz, pyrite, galena, sphalerite, etc. It is found in fine crystals from Schlaggenwald, Bohemia, and in the various tin districts of Saxony and Cornwall. ...
How long does it take for natural Earth processes to form hydraulic fractures? Is the formation driven by sediment compaction, oil and gas generation, or something else? What role do these natural fractures play in modern hydraulic fracturing production? A new GSA BULLETIN study by András Fall ...
