New research suggests a new solar energy design, inspired by nature, may pave the way for future renewable energy technologies.

Photovoltaic solar energy is obtained by converting sunshine into electricity—and researchers from Imperial have developed a new leaf-like design with increased efficiency.

The new photovoltaic leaf (PV-leaf) technology uses low-cost materials and could inspire the next generation of renewable energy technologies.

A series of experiments has demonstrated that a PV-leaf can generate over 10% more electricity compared to conventional solar panels, which lose up to 70% of the incoming solar energy to the environment...

Researchers have demonstrated how CO2 can be captured from industrial processes – or even directly from the air – and transformed into clean, sustainable fuels using just the energy from the Sun.

The researchers, from the University of Cambridge, developed a solar-powered reactor that converts captured CO2 and plastic waste into sustainable fuels and other valuable chemical products. In tests, CO2 was converted into syngas, a key building block for sustainable liquid fuels, and plastic bottles were converted into glycolic acid, which is widely used in the cosmetics industry.

Unlike earlier tests of their solar fuels tec...

Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States.

Vibrio vulnificus bacteria grow in warm shallow coastal waters and infect a cut or insect bite during contact with seawater. A new study led by the UK’s University of East Anglia (UEA) shows that the number of V. vulnificus infections along the East Coast of the US, a global hotspot for such infections, has gone up from 10 to 80 per year over a 30-year period.

In addition, every year cases occur further north. In the late 1980s, cases were found in the Gulf of Mexico and along the southern Atlantic coast but were rare north of Georgia. Today they can be found as far north as Philadelphia.

Per- and polyfluoroalkyl substances (PFAS) are potentially harmful substances known as “forever chemicals” because they are so difficult to destroy. One emerging technique to degrade PFAS involves forcefully grinding them with metal balls in a moving container, but this technique can require corrosive additives. Now, in Environmental Science & Technology Letters, researchers report a new type of additive for “ball milling” that completely breaks down PFAS at ambient temperature and pressure.

Solid PFAS contamination is an ongoing issue for soil near waste sites, manufacturing sites, and facilities that frequently use firefighting foam. Currently, the U.S...
