Bayesian probability-based computer program rolls the dice on perovskite interfaces

Perovskites are a type of mineral and class of materials, and have been attracting a great deal of attention for their potential applications to technologies such as those used in solar cells. These unique materials have well-ordered structures and show many interesting properties that could be useful in other areas of electronics. Such a variety of properties in the same structural backbone allows different kinds of perovskites, with different properties, to be evenly joined together without breaking lattice coherency. Being able to examine the structures at these interfaces is important for researchers studying perovskites, but currently used techniques have insufficient resolution or produce complex results that are very difficult to analyze.

Six degrees of separation: Why it is a small world after all

It’s a small world after all – and now science has explained why. A study conducted by the University of Leicester and KU Leuven, Belgium, examined how small worlds emerge spontaneously in all kinds of networks, including neuronal and social networks, giving rise to the well-known phenomenon of “six degrees of separation”.

First materials to be woven at the atomic and molecular levels created

There are many different ways to make nanomaterials but weaving, the oldest and most enduring method of making fabrics, has not been one of them – until now. An international collaboration led by scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, has woven the first three-dimensional covalent organic frameworks (COFs) from helical organic threads. The woven COFs display significant advantages in structural flexibility, resiliency and reversibility over previous COFs – materials that are highly prized for their potential to capture and store carbon dioxide then convert it into valuable chemical products.

First detailed picture of a cancer-related cell enzyme in action on a chromosome unit

A landmark study to be published in the October 30, 2014 print edition of the journal Nature provides new insight into the function of an enzyme related to the BRCA1 breast-cancer protein. The study by a team at Penn State University is the first to produce a detailed working image of an enzyme in the Polycomb Repressive Complex 1 (PRC1)-a group that regulates cell development and is associated with many types of cancer.

Floating Seawer Skyscraper Rids The World’s Oceans Of Plastic While Generating Clean Energy

Seawer is a self-supported hydroelectric power station that can generate electricity using seawater at the same time that it cleans up plastic waste. The huge structure separates plastic particles and fluids, recycles seawater and releases it back into the ocean. The structure receives energy from the sun, ocean and plastics and moves slowly from one polluted area …
