X-Ray Optics on a Chip

Aug. 18, 2016 — Waveguides are widely used for filtering, confining, guiding, coupling or splitting beams of visible light. However, creating waveguides that could do the same for X-rays has posed tremendous ... read more

Aug. 15, 2016 — A graduate student has devised an ingenious way to make tiny knotted and interlocked chemical structures that have been impossible for chemists to fabricate until ... read more

Aug. 15, 2016 — Graphene nanoribbons twist and bend like DNA or proteins in a solution and their rigidity can be tuned, making them potentially useful for biomimetic applications, according to ... read more

Aug. 12, 2016 — An international team's findings provide important clues for designing polymer solar cells approaching target for power conversion efficiency and optimized for roll-to-roll ... read more

Silicon Brings More Color to Holograms

Aug. 12, 2016 — Silicon holograms harness the full visible spectrum to bring holographic projections one step closer, report scientists. A research team has now demonstrated the hologram of three flat images at ... read more

Simplified Approach to Drug Development With Upsalite

Aug. 10, 2016 — For the first time, researchers have revealed the nanostructure of the mesoporous magnesium carbonate Upsalite and pore size control was achieved without organic templates or swelling agents. By ... read more

Aug. 10, 2016 — Atomic force microscopes make the nanostructure of surfaces visible. Their probes scan the investigation material with finest measurement needles. Researchers have now succeeded in adapting these ... read more

Aug. 9, 2016 — Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the ... read more

Scientists Count Microscopic Particles Without Microscope

Aug. 9, 2016 — Scientists put forward a simple new way of counting microscopic particles in optical materials. A laser beam passing through such a material splits and forms a pattern of numerous bright spots on a ... read more

Aug. 9, 2016 — What does one need to strengthen or toughen concrete? A lot of nothing. Or something, say investigators in a new ... read more

Aug. 8, 2016 — Scientists have just developed a way to direct the self-assembly of multiple molecular patterns within a single material, producing new nanoscale architectures. This is a significant conceptual leap ... read more

Aug. 8, 2016 — The capacity of lithium-ion batteries might be increased by six times by using anodes made of silicon instead of graphite. Researchers have observed for the first time in detail how lithium ions ... read more

Researchers Combine Simulation, Experiment for Nanoscale 3-D Printing

Aug. 6, 2016 — A research team has created a high-power simulation and design process to print free-standing 3-D structures on the nanoscale using focused electron beam induced deposition. The simulation-guided ... read more

Aug. 4, 2016 — An X-ray microscopy technique has given scientists the ability to image nanoscale changes inside lithium-ion battery particles as they charge and discharge. The real-time images provide a new way to ... read more

Aug. 4, 2016 — Researchers have developed a computer model that will aid in the design of nanocarriers, microscopic structures used to guide drugs to their targets in the body. The model better accounts for how the ... read more

Aug. 4, 2016 — Scientists have created randomly spiking neurons using phase-change materials to store and process data. This demonstration marks a significant step forward in the development of energy-efficient, ... read more

Aug. 3, 2016 — Researchers have created a new silicon-tin nanocomposite anode that could lead to lithium-ion batteries that can be charged and discharged more times before they reach the end of their useful lives. ... read more

Aug. 3, 2016 — Researchers have discovered that gallium nanoparticles can form a solid core surrounded by a liquid outer layer over a temperature span of 1000 degrees Fahrenheit. The discovery marks the first time ... read more

Aug. 3, 2016 — Aerospace engineers have designed carbon nanotube 'stitches' that strongly bind composites, which could produce lighter, more damage-resistant ... read more

Aug. 3, 2016 — Converting light from one wavelength to a shorter wavelength is typically inefficient. To tackle that inefficiency, a team built a structure with metallic cavities that improves the light conversion ... read more
