Researchers Develop a Series of Novel Host-Guest Organic Phosphorescence Systems

Purely organic room-temperature phosphorescence (RTP) materials have been a hot research topic. Currently, the pure RTP materials have been realized by the introduction of heavy halogen atoms, carbonyls groups or some heteroatoms, hydrogen bonding, H-aggregation, strong intermolecular electronic coupling, molecular packing, host-guest interaction, etc.

Scientists Investigate Oxygen-Promoted Synthesis of Armchair Graphene Nanoribbons on Cu(111)

On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular, graphene nanoribbons (GNRs), a category of quasi-1D nanomaterials derived from graphene, have been widely studied due to their tunable electronic properties and potential applications in semiconductor devices, such as field-effect transistors and spintronics.

Depositing Fe Species into the Micropores of ZSM-5 to Prepare FeOx/ZSM-5 Catalysts

The directly catalytic oxidation of alkanes has high atomic economy and application value to form corresponding chemical organic products such as alcohols, aldehydes, ketones and carboxylic acid. It is challenging to achieve efficient and selective oxidation of alkane under mild conditions due to the inert C-H bonds of alkanes.

A New Way to Obtain Polarity and Photovoltaic Behavior from 2D Materials

For the first time, researchers have discovered a way to obtain polarity and photovoltaic behavior from certain nonphotovoltaic, atomically flat (2D) materials. The key lies in the special way in which the materials are arranged. The resulting effect is different from, and potentially superior to, the photovoltaic effect commonly found in solar cells.

Tantalum Nitride has Optimal Thermal Conductivity

A thermos bottle has the task of preserving the temperature - but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed. This requires special materials with particularly good heat conduction properties.
