A new Chemistry in Pictures exhibit went up July 1 at ShanghaiTech University. With images ranging from nano to macro, the show hightlights the power and beauty of chemistry and its allied science. Many thanks to those whose work is included, and to our translators, proofreaders, and collaborators at STU.

Here’s a link to STU’s press release about the exhibit

Part of our plan with the re-digging of our pond, #PondLife, was to create a slightly wild area behind the pond and a second patch adjacent. I planted various seeds and also let the grass grow, mowing up to an imaginary curved border tangential and sweeping from pond to compost bins. We have some Red … Continue reading "Wilding the garden #WildFlowers"

Eating through iron

In nature, water can be acidified by sulfate and chloride salts, dissolved carbon dioxide, and certain types of bacteria. And acidic water can corrode metal equipment that is exposed to it for long periods of time, like in heat exchangers used to extract geothermal energy from underground fluids. Sami Khan demonstrated what corrosion looks like on this 500 nm thick layer of iron coating a silicon substrate by dropping hydrochloric acid (pH 1.5) onto it. Almost immediately... Читать дальше...
