Nanotechnology designed to speed up the hardening of concrete
It has been possible to demonstrate scientifically that tobermorite can be produced at 400 C when above 200 C it had been thought to be impossible. This mineral has been found in concrete buildings dating back to Roman times and could hold the key to their durability.

Predicting the movement and impacts of microplastic pollution
Microplastics, which are particles measuring less than 5 mm, are of increasing concern. They not only become more relevant as other plastic marine litter breaks down into tiny particles, they also interact with species in a range of marine habitats. A study in Integrated Environmental Assessment and Management takes a look at how global climate change and the impact of changing ocean circulation affects the distribution of marine microplastic litter.

MIT engineers manipulate water using only light
A new system developed by engineers at MIT could make it possible to control the way water moves over a surface, using only light. This advance may open the door to technologies such as microfluidic diagnostic devices whose channels and valves could be reprogrammed on the fly, or field systems that could separate water from oil at a drilling rig, the researchers say.

Science Advances
Self-assembled nanostructures can be selectively controlled
Plasmonic nanoparticles exhibit properties based on their geometries and relative positions. Researchers have now developed an easy way to manipulate the optical properties of plasmonic nanostructures that strongly depend on their spatial arrangement. 'The challenge is to make the structures change their geometry in a controlled way in response to external stimuli. In this study, structures were programmed to modify their shape by altering the pH,' tells Assistant Professor Anton Kuzyk from Aalto University.

Chip-based nanoscopy: Microscopy in HD quality
Physicists at Bielefeld University and the Arctic University of Norway in Tromsø have developed a photonic chip that makes it possible to carry out super-resolution light microscopy, also called 'nanoscopy,' with conventional microscopes. In nanoscopy, the position of single fluorescent molecules can be determined with a precision of just a few nano-meters, that is, to a millionth of a millimeter.

Freezing lithium batteries may make them safer and bendable
Columbia Engineering Professor Yuan Yang has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage. The study is published online April 24 in Nano Letters.

Solar cell design with over 50 percent energy-conversion efficiency
Solar cells convert the sun's energy into electricity by converting photons into electrons. A new solar cell design could raise the energy conversion efficiency to over 50 percent by absorbing the spectral components of longer wavelengths that are usually lost during transmission through the cell. These findings were published on April 6 in the online edition of Nature Communications.

Electrochemical performance of lithium-ion capacitors
Pre-lithiated multiwalled carbon nanotubes and activated carbon (AC) materials were used as anode and cathode respectively for Lithium-ion capacitors (LICs). The pre-lithiatiation was performed using internal short circuit approach (ISC). The LIC showed excellent supercapacitor performance. The pre-lithiated MWCNTs have a potential application as anode for high performance Lithium-ion capacitors.

Crystals grown aboard space station provide radiation detecting technology
Research into crystal growth in microgravity was one of the earliest investigations conducted aboard the International Space Station and is continued to this day. The unique microgravity environment of space provides an ideal setting for producing crystals that are more perfect than their terrestrial-grown counterparts. The Crystal Growth of Cs2LiYCl6:Ce Scintillators in Microgravity (CLYC-Crystal Growth), a Center for the Advancement of Science in Space (CASIS)-sponsored investigation, will study the potential benefits of growing the CYLC crystal in microgravity.

Ben-Gurion U. researchers develop membranes that remove viruses from drinking water
The 'zwitterionic polymer hydrogel' repels the viruses from approaching and passing through the membrane. It contains both positive and negative charges and improves efficiency by weakening virus accumulation on the modified filter surface. The result was a significantly higher rate of removal of waterborne viruses, including human norovirus and adenovirus.
