Making batteries from waste glass bottles

Researchers have used waste glass bottles and a low-cost chemical process to create nanosilicon anodes for high-performance lithium-ion batteries. The batteries will extend the range of electric vehicles and plug-in hybrid electric vehicles, and provide more power with fewer charges to personal electronics like cell phones and laptops.

Nanoparticles remain unpredictable

The way that nanoparticles behave in the environment is extremely complex. There is currently a lack of systematic experimental data to help understand them comprehensively, as environmental scientists have shown in a large overview study. A more standardized approach would help to advance the research field.

Better living through pressure: Functional nanomaterials made easy

Using pressure instead of chemicals, nanoparticles have been fabricated into nanowire arrays similar to those that underlie touch-screens for phones, computers, TVs, and sensors. The pressure process takes nanoseconds instead of the hours required by industry’s current chemical means, say investigators.

Harnessing heat to power computers

Heat is commonly regarded as computing’s mortal enemy. Two researchers, however, flipped the question of how to keep computers cool to how to use heat as an alternative energy source.

Scientists combine a peptide with a nano cancer drug formulation to improve treatment effectiveness and prevent metastasis in pancreatic cancer

Scientists have unlocked an important mechanism that allows chemotherapy-carrying nanoparticles—extremely small objects between 1 and 100 nanometers (a billionth of a meter)—to directly access pancreatic cancer tumors, thereby improving the ability to kill cancer cells and hence leading to more effective treatment outcome of the disease. The researchers also confirmed the key role of a peptide (an extremely small protein) in regulating vascular access of the nanoparticle to the cancer site.

Method to control light propagation in waveguides invented

Engineers have invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. They built photonic integrated devices that had record-small footprints and were also able to maintain optimal performance over an unprecedented broad wavelength range. The method could lead to faster, more powerful, and more efficient optical chips, which in turn could transform optical communications and optical signal processing.
