New materials will have applications in electronic and optoelectronic devices, electrocatalysis, electroanalysis and sensors
Four different topological types, named UCR-20, UCR-21, UCR-22 and UCR-23, that the new zeolite analog materials possess. Each topological type can be made in a variety of chemical compositions. (A) The 3-dimensional sodalite-based framework in UCR-20. (B) Supertetrahedral clusters are joined into a 6-membered ring in UCR-21 with a cubic ZnS (zinc sulfide) type framework. (C) The 3-dimensional framework of UCR-22 with the cubic ZnS type framework decorated with the core-less supertetrahedral cluster. (D) The 3-dimensional framework of UCR-23 showing channels with the pore size consisting of 16 tetrahedral atoms.
Scientists at the University of California, Riverside have synthesized a large family of semiconducting porous materials that have an unprecedented and diverse chemical composition.
The new materials show several different properties such as photoluminescence, ion exchange, and gas sorption. They also have a large surface area and uniform pore sizes. In addition, they have a pore size larger than zeolites. The synthetic approach has the potential to generate new materials with even larger pore sizes, the scientists report in Science.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
