Sustainable Development - Durability of a Structural Lightweight Concrete with Expanded Glass and Silica Fume

Figure1_1.jpg

As the single most widely used construction material in the world, concrete is of substantial interest in relation to sustainable development. There are many environmental consequences induced by the consumption of raw materials but also interesting opportunities of recycling waste materials that can improve its sustainability.

Researchers Discover a New Type of Memory Effect in Transition Metal Oxides

A new kind of memory effect discovered in two Transition Metal Oxides could carry important repercussions on technology and security. The multi-state nature of the memory effect, whereby more than one piece of information can coexist in the same space, could be harnessed for memory technology. And while deleted computer data can be recovered, at least partially, by talented hackers, the "erase-upon-reading" property of this system could make an invaluable contribution to security technologies.

How Do Metals Interact with DNA?

figure1_web.jpg

Since a couple of decades, metal-containing drugs have been successfully used to fight against certain types of cancer. The lack of knowledge about the underlying molecular mechanisms slows down the search for new and more efficient chemotherapeutic agents. An international team of scientists, led by Leticia González from the University of Vienna and Jacinto Sá from the Uppsala University, have developed a protocol that is able to detect how metal-based drugs interact with DNA.

Berkeley Lab Researchers Make NWChem’s Planewave “Purr” on Intel’s Knight Landing Architectures

Water-KNL.jpg

Berkeley Lab researchers have successfully added thread-level parallelism on top of MPI-level parallelism in the planewave density functional theory method within the popular software suite NWChem. An important step to ensuring that computational chemists are prepared to compute efficiently on next-generation exascale machines.

‘Flying Saucer’ Colloidal Quantum Dots Produce Brighter, Better Lasers

LeadImage_KevinSoobrian.1.jpg

A multi-institutional team of researchers from Canada and the US has demonstrated steady state lasing with solution-processed nanoparticles called “colloidal quantum dots,” an important step on the path to improving laser tools for fiber optics, video projectors and more accurate medical testing technology. The work is reported today in a paper for the journal Nature.
