Delocalizing electron distribution in thermally activated delayed fluorophors for high-efficiency and long-lifetime blue electroluminescence The stability and efficiency of thermally activated delayed fluorescent (TADF) emitters are still limited. Here the authors design TADF compounds by introducing an auxil...
Pre-adsorption of water molecules on a material surface, followed by assembly of a van der Waals (vdW) structure, provides a vdW water gap with a height that can be precisely tuned through variation of the amount of water adsorbed at the interface. This approach is applicable to different tw...
Ligation efficiency is critical for conversion of DNA fragments into sequenceable molecules and thus impacts conversion rate and yield of the libraries. Because library fragments are flanked by adapters, they are sometimes called inserts...
When molecules come to life – Using Augmented reality for studying protein structure in Cell Biology classMost Undergraduate Biology courses cover an incredibly large range of topics integrating complex information at molecular, cellular, genetic and at the organismal lev...

For the first time, chemists have successfully produced amino acid-like molecules that all have the same 'handedness', from simple building blocks and in a single test tube. Could this be how life started. On earth? Or in space, as the Philae lander is currently exploring? René Steendam ...
moisture (潮气),making donor organs unsuitable for transplantation.Thus,organs can be made cold for only a few hours ahead of a procedure.But a set of lasting new antifreeze compounds (化合物)-similar to those found in particularly hardy (耐寒的) animals-could lengthen organs' she...
Infection is initiated by contact of the virus with the cell surface, followed by attachment to specific cell-surface molecules. Nonspecific and low-affinity interactions with abundant cell-surface molecules, which are sometimes called attachment factors, concentrate the virus on the plasma membrane to...
AMPs represent an important part of defense strategies against pathogenic microbes, and are produced by both eukaryotic and prokaryotic life forms, although the majority of identified AMPs are from animals4. Due to the increasing prevalence of multidrug-resistant bacteria, AMPs have received considerable...
