Direct observation of giant molecules

Physicists at the Max Planck Institute for Quantum Optics (MPQ) achieved to form giant diatomic molecules and optically detect them afterwards by using a high-resolution objective.

Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published ...

A laser focus on finding better ways to make renewable fuels

In the search for alternatives to oil-based fuels, one of the most promising, and challenging, strategies involves splitting water. Researchers have for decades made strides in using sunlight to split water molecules into ...

Understanding and controlling the molecule that made the universe

Trihydrogen, or H3+, is acknowledged by scientists as the molecule that made the universe. In recent issues of Nature Communications and the Journal of Chemical Physics, Michigan State University researchers employed high-speed ...

When changing one atom makes molecules better

The development and improvement of pharmaceuticals plays the central role in the ongoing battle against human disease. Organic synthesis is the field that enables these developments as it offers the toolbox to diversify chemical ...

Forming the ion that made the universe

The trihydrogen cation, H3+, is the starting point for almost all molecules in the universe. Typically, H3+ is formed by collisions involving hydrogen gas, but its chemistry at the molecular level is relatively unknown. When ...

Turning a porous material's color on and off with acid

A research team led by Hokkaido University in Japan has constructed a porous material that is very stable and changes color when exposed to acid vapor. This is believed to be the first reported instance of a hydrogen-bonded ...
