Catalyzing a zero-carbon world by harvesting energy from living cells

Scientists have achieved a breakthrough in converting energy-deficient metabolites to a biorenewable resource thanks to a versatile catalyst

16-Nov-2020

The imminent environmental crisis calls for an urgent transition to a green economy. A team of scientists at Nagoya University, Japan, led by Professor Susumu Saito, has recently found an interesting way to make this happen -- by leveraging an important metabolic pathway in living cells. Their ...

Cheaper and easier way found to make plastic semiconductors

26-Apr-2018

Cheap, flexible and sustainable plastic semiconductors will soon be a reality thanks to a breakthrough by chemists at the University of Waterloo. Professor Derek Schipper and his team at Waterloo have developed a way to make conjugated polymers, plastics that conduct electricity like metals, ...

Channeling graphene to understand filtration and ion transport into cells

12-Dec-2017

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells. ...

Customized catalysts to boost product yields, decrease separation costs

20-Oct-2017

For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy's Oak Ridge National Laboratory. The investigators discovered that treating a complex oxide crystal with either heat or chemicals caused ...

A more energy-efficient catalytic process to produce olefins

01-Jun-2017

Research at the University of Pittsburgh led to a more energy-efficient catalytic process to produce olefins, the building blocks for polymer production. The team's investigations could influence potential applications in diverse technology areas from green energy and sustainable chemistry to ...

MOFs provide a better way to remove water from gas

22-May-2017

The conventional view that metal-organic frameworks (MOFs) cannot be stable in water has been overturned by the development of an MOF that can selectively and effectively adsorb water to dry gas streams. "The achievement of energy efficient dehydration by our MOF is revolutionary," said Professor ...

People consuming high amounts of energy drinks ignore the pick-me-up risk

BfR study examines the drinking habits at festivals, sports events, LAN parties and in discos

12-Feb-2014

Some visitors to discotheques, music and sports events and LAN parties drink considerable amounts of so-called energy drinks used for pick-me-up. On average, the persons questioned consumed approx. 1 litre of energy drink mixed with alcoholic beverages while dancing in clubs. "Up to 5 litres were ...

The contribution of particulate matter to forest decline

20-Jun-2013

Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Bonn University scientists have now discovered a responsible mechanism: particulate matter salt compounds that become deliquescent because of humidity and form a wick-like ...

Self assembled nanostructures for hostile environments

Scientists at Tokyo Tech have developed a new self-assembled nanostructure that can survive very hot or saline environments

29-May-2013

Nanostructures that assemble themselves from polymer molecules could prove to be useful tools in chemistry and industry. However, it is difficult to develop structurally robust self-assembling materials because they are often adversely affected by their surroundings. Many natural organisms have ...

MOF-polymer composite membranes to enhance proton conductivity in fuel cells

07-Dec-2012

Nafion (a perfluorosulfonic acid membrane) is widely used in fuel cells to conduct protons, but Nafion membranes are prone to rapid dehydration at low humidity, which results in a loss of conductivity. To overcome this problem, scientists in China have made a metal-organic framework (MOF) ...
