Boron nitride separation process could facilitate higher efficiency solar cells

A team of semiconductor researchers has used a boron nitride separation layer to grow indium gallium nitride (InGaN) solar cells that were then lifted off their original sapphire substrate and placed onto a glass substrate.

Charged polymer nanoballs attack tumors directly, without drugs

By using nanosized charged polymer balls to attack tumors directly rather than carry drugs, researchers have found a way to overcome drug resistance.

Tuning into the potential of phosphorene

Better understanding of the wetting characteristics of phosphorene could pave the way for new applications in biological engineering.

Building miniature lasers using nanowire

Researchers have built a miniature laser in the form of a nanowire. It's the uniformity of the superlattice of the nanowire that makes this miniature laser exceptional.

International nanotechnology authorities dialogue

At this recent meeting, environmental, health and workers protection authorities as well as industry, science and civil society organisations discussed current topics in the area of nano governance.

Friction loss at first contact: The material does not forgive

The exact cause of wear is still unclear. Scientists recently proved that the effect occurs at the first contact already and always takes place at the same point of the material. Their findings help develop optimized materials and reduce consumption of energy and raw materials.

Environmentally friendly photoluminescent nanoparticles for more vivid display colors

Researchers created a new type of light-emitting nanoparticle that is made of ternary non-toxic semiconductors to help create displays and LED lighting with better colors that are more environmentally friendly.

Watching 2D materials grow

Atomically thin crystals will play an ever greater role in future -- but how can their crystallisation process be controlled? A new method is now opening up new possibilities.

Science behind world's lightest graphene watch revealed

The RM 50-03 watch was made using a unique composite incorporating graphene to manufacture a strong but lightweight new case to house the watch mechanism which weighed just 40 grams in total, including the strap.
