Advanced Materials
First luminescent molecular system with a lower critical solution temperature
Osaka University researchers developed a luminescent small-molecule system that changes from a solution to a suspension when heated. The solubility change is accompanied by a color change in the photoemission from blue to green. The transition is mediated by oleic acid and methylamine, which aid the reversible reorganization from molecular wires in solution through an intermediate co-crystal and finally into nanoparticles at higher temperatures. This new system could aid the development of new-generation thermo-responsive materials.

Thin layers of water hold promise for the energy storage of the future
Researchers have found that a material which incorporates atomically thin layers of water is able to store and deliver energy much more quickly than the same material that doesn't include the water layers. The finding raises some interesting questions about the behavior of liquids when confined at this scale and holds promise for shaping future energy-storage technologies.

Looking for the quantum frontier
Researchers have developed a new theoretical framework to identify computations that occupy the 'quantum frontier' -- the boundary at which problems become impossible for today's computers and can only be solved by a quantum computer. The team, whose work was highlighted in the first edition of Quantum journal this week, demonstrate that these computations can be performed with near-term, intermediate, quantum computers.

Video captures bubble-blowing battery in action
PNNL researchers have created a unique video that shows oxygen bubbles inflating and later deflating inside a tiny lithium-air battery. The knowledge gained from the video could help make lithium-air batteries that are more compact, stable and can hold onto a charge longer.

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.

UCI physicists design 2-D materials that conduct electricity at almost the speed of light
Physicists at the University of California, Irvine and elsewhere have fabricated new two-dimensional quantum materials with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics. In three separate studies appearing this month in Nature, Science Advances and Nature Materials, researchers explored the physics behind the 2-D states of novel materials and determined they could push computers to new heights of speed and power.

Seeing is believing: Diamond quantum sensor reveals current flows in next-gen materials
In a world-first, researchers have imaged electrons moving in graphene using a quantum probe found only in diamonds. The technique could be used to understand electron behavior and allow researchers to improve the reliability and performance of existing and emerging technologies. These images could reveal the microscopic behavior of currents in quantum computing devices, graphene and other 2-D materials, and be used to develop next generation electronics, energy storage (batteries), flexible displays and bio-chemical sensors.

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.

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.
