Unfortunately, this new breakthrough involves #Molybdenum, the mining of which is very polluting. The article does also mention breakthroughs using #perovskite, and hopefully, lead-free perovskite (like those using tin) will be developed... Always ask -- How long will this new technology last? What happens when it becomes obsolete? Are there polluting materials involved?

China curbs exports of five metals. What are they used for?

China has announced sweeping export restrictions on five metals used in the defence, clean energy and other industries.

Here is what you need to know about them:

#tungsten
#indium
#bismuth
#tellurium
#molybdenum

#Sponges' #symbiosis with #bacteria helps them store toxic #molybdenum to keep predators away

Out of the blue: Hyperaccumulation of molybdenum in the Indo-Pacific sponge Theonella conica https://www.science.org/doi/10.1126/sciadv.adn3923

"Entotheonella serves as a detoxifying organ for accumulating metals inside the body of its #sponge hosts. Hoarding more and more molybdenum, the bacteria convert it from its toxic soluble state into a mineral."

A Multi-Billion-Dollar Question – Researchers Are Closer to Understanding Hydrogen’s Great Challenge

Theoretical models have indicated that carbon vacancies in metal #carbide precipitates are effective H traps..Increasing the number of carbon vacancies in individual metal carbides is important since the overall hydrogen trapping capacity can be leveraged by introducing abundant metal carbides..we compare a reference #steel..with an experimental steel added with #molybdenum (Mo), which form Ti-Mo carbides comprising more carbon vacancies than TiCs."

"Here we report an integrated 32 × 32 #vector–#matrix multiplier with 1,024 floating-gate field-effect #transistors that use #monolayer #molybdenum disulfide as the channel material. In our wafer-scale fabrication process, we achieve a high yield and low device-to-device variability, which are prerequisites for practical applications"

Moonlighting Arabidopsis molybdate transporter 2 family and GSH-complex formation aid molybdenum homeostasis

https://www.nature.com/articles/s42003-023-05161-x

Scientists identified a secondary molybdenum (Mo) transporter in Arabidopsis assisting in Mo distribution—an essential plant micronutrient. They also found a glutathione-molybdate complex that ensures storage stability in plants, advancing the understanding of molybdenum philosophy in flora. 🌱

Molybdenum: atomic number: 42; weight: 95.95; Transition metal; discovery: 1778,1781—Carl Wilhelm Scheele, Peter Jacob Hjelm #Poetry #Science #History #Molybdenum (https://sharpgiving.com/thebookofscience/items/e042.html)

Based on a nanosystem, the core of which is #polyoxometalate (containing #molybdenum and iron). A broad-spectrum #antibiotic, #tetracycline, is attached to the surface of the polyoxometalate.

Chemistry Lab from my environmental chemistry class earlier this year:

The determination of phosphorous in environmental water can be determined by creating molybdenum Blue. 💙 Phosphate is converted into Molybdenum Blue. We used UV-Vis spectroscopy to quantitatively determine phosphate concentration in water samples. #RealTimeChem #chemistry #chemistrylab #chemistrythings #chemistrylover #chem #molybdenum
