Exploring the origin of 'black widow' pulsars

Ph.D. candidate GUO Yunlang and Prof. WANG Bo from the Yunnan Observatories of the Chinese Academy of Sciences investigated the formation of black widow pulsars through ultracompact X-ray binaries (UCXBs) with He star companions.

Watching solar cells grow

(Phys.org) —For the first time, a team of researchers at the HZB led by Dr. Roland Mainz and Dr. Christian Kaufmann has managed to observe growth of high-efficiency chalcopyrite thin film solar cells in real time and to ...

Stabilisation of microdroplets using ink jet process

Progress means that many things that are used in everyday life are becoming more manageable, practical and generally smaller. This also applies to biological and chemical experiments. To save material and resources, scientists ...

Did early mammals turn to night life to protect their sperm?

Humans are diurnal—we are active in the day and sleep at night. But diurnalism is by far the exception rather the rule in mammals. About 250-230 million years ago, the mammalian ancestors, called the therapsids, became ...

Evaporation dynamics at the nano- and micro-scale

A new evaporation dynamics study finds that very small droplets evaporate more slowly than predicted by current models. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw, ...
