Organometallic Chemistry

Molecular hard drives offer greater storage and use less energy

Allergic reactions to vitamin B12 are rare, but real. The reason may sound strange, but it's true - an allergy to cobalt. What's going on here? The Food Babe has a possible suggestion, but it's ridiculous. Let's sort this out.

The Chirik Group at the Princeton Department of Chemistry is chipping away at one of the great challenges of metal-catalyzed C–H functionalization with a new method that uses a cobalt catalyst to differentiate between bonds in fluoroarenes, functionalizing them based on their intrinsic electronic properties.

In Austria, TU Wien researchers recognised the potential of MOCHAs— organometallic chalcogenolate compounds— as catalysts and conducted experiments with them for the first time. However, they were faced with some problems: Previous synthesis methods only yielded small amounts of product and required a lot of time. Initial tests showed that the catalytic performance of MOCHAs […]

Nine members of the MIT faculty are among 126 early-career researchers honored across seven fields with 2023 Sloan Research Fellowships by the Alfred P. Sloan Foundation. The honorees will each receive a two-year, $75,000 fellowship to advance their research.

The Seebeck effect is a thermoelectric phenomenon by which a voltage or current is generated when a temperature difference exists across a conductor. This effect is the basis of established and emerging thermoelectric applications alike, such as heat-to-electricity energy harvesters, sensing devices, and temperature control.

Chemists from Freiburg have succeeded in converting polynuclear transition metal carbonyls into their homoleptic complex cations using typical inorganic oxidants. In their work, the research team of Malte Sellin, Christian Friedmann and Prof. Dr. Ingo Krossing from the Institute of Inorganic and Analytical Chemistry and Maximilian Mayländer and Sabine Richert from the Institute of Physical Chemistry at the…

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have prepared an organometallic complex from 0.3 milligrams of berkelium-249.

Carbon dioxide (CO2) is the most abundant greenhouse gas causing climate change but has existed on Earth long before humans started releasing it into the atmosphere at unprecedented levels. As such, some of the planet's earliest organisms evolved to harness and make use of this gas that is otherwise harmful to humans and the planet.

Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear.

Organoberyllium sandwich compound should provide answers to questions first posed a century ago

In the field of molecular magnetism, the design of devices with technological applications at the nanoscale—quantum computing, molecular spintronics, magnetic cooling, nanomedicine, high-density information storage, etc.—requires those magnetic molecules that are placed on the surface to preserve their structure, functionality and properties.

Doesn't "organometallic sandwich" sound appetizing?

Researchers have applied artificial photosynthesis as the basis for developing new sustainable processes.

An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers have found. Careful study of the enzyme has led chemists from the University of Illinois Urbana-Champaign to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.

Plants use photosynthesis to harvest energy from sunlight. Now researchers at the Technical University of Munich (TUM) have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.

A new type of catalyst breaks down polyolefin plastics into new, useful products. This project is part of a new strategy to reduce the amount of plastic waste and its impact on our environment, as well as recover value that is lost when plastics are thrown away. The catalyst was developed by a team from the Institute for Cooperative Upcycling of Plastic (iCOUP), a U.S. Department of Energy, Energy Frontier Research…

Researchers created a new catalyst that transforms hydrocarbons into chemicals and materials that are higher value, easier to recycle, and biodegrade in the environment. This catalyst transforms materials such as motor oil, plastics in single-use grocery bags, water or milk bottles, and their caps, and even natural gas. It was developed by a team of scientists led by Aaron Sadow, a scientist at Ames National…
