Exciting times for efficient heavy-atom-free OLEDs

(Osaka University) An international team including researchers from Osaka University has created an OLED material that combines the mechanisms of thermally activated delayed fluorescence and room-temperature phosphorescence. The hybrid emitter contains only abundant elements, making it more cost-effective and sustainable than heavy-atom-containing alternatives. By combining the two mechanisms the researchers demonstrated the most efficient heavy-atom-free RTP-based OLED to date. It is hoped that the findings will lead to more sustainable display technology.

Supercapacitors challenge batteries

(Technical University of Munich (TUM)) A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries.

Sikhs Hand Out Thousands of Meals to Stranded Truckers–Then Fill 1,000 Sandbags For Flood Victims

A group of volunteers who handed out thousands of meals to stranded truckers in Kent are now helping flood victims hit by Storm Bella. Members of Khalsa Aid International dished out 1,000 pizzas and 1,500 bowls of curry and pasta to truck drivers in the days running up to Christmas. But within hours of leaving […]

UV-emitting LED lights found to kill coronavirus

Researchers have shown that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be available for private and commercial use.

UN climate summit president thanks Australian states – but not Morrison government – for backing net zero

The British president of the next major UN climate change summit has pointedly thanked Australia’s states and territories for backing a goal of net zero emissions by 2050 while urging unnamed others – including the Morrison government – to join…

Sniffing your way to the gym

(University of California – Riverside) On a near daily basis, the internet spews out numerous tips and tricks for exercise motivation. Now we can add smell to the long and growing list. A research team led by a scientist at the University of California, Riverside, has found olfaction–or smell–may play an important role in motivating mammals to engage in voluntary exercise. Performed in lab mice, the study may open up new areas of research and have relevance for humans.

Grave of 9,000-Year-old Skilled Huntress Found in the Peruvian Andes, Changing the Stereotype of “Man the Hunter”

When a grave containing the remains of a 9,000-year-old human alongside an extensive hunter’s tool kit was discovered, archaeologists reckoned they had found a great chief—a revered hunter. However, bio-archaeologist Jim Watson of the University of Arizona informed the discoverers who were working high in the Peruvian Andes mountains that, based on the dimensions of […]

Light pollution at night severely disrupts the reproductive cycle of corals

Studying the reproductive cycle of two coral species from the Indo-Pacific Ocean over the course of three months, researchers found that light pollution caused delayed gametogenesis and unsynchronized gamete release. To shed light on the findings, they created a first-of-its-kind global map that highlights areas in the world most threatened by nighttime artificial light. This light pollution impact assessment can help incorporate an important variable in coral reef conservation planning near areas of human activity.
