Nanoparticle sunscreen ingredient may prevent medical implant infections

A common ingredient in sunscreen could be an effective antibacterial coating for medical implants such as pacemakers and replacement joints.

Nanotechnology advances could pave way for implantable artificial kidney

Advances in nanofilter technology could lead to the development of a surgically implantable, artificial kidney.

Onion-like layers help this efficient new nanoparticle glow

A dye-coated surface is 1 of 3 specially crafted layers that help the particle emit light ideal for bioimaging.

Ultra-thin, tunable, broadband microwave absorber may advance radar cloaking

Researchers have developed an ultra-thin, tunable broadband microwave absorber for ultra-high frequency applications. This ultra-thin absorbing surface, called an active frequency-selective surface absorber, consists of arrays of patterned conductors loaded with two common types of circuit elements known as resistors and varactors.

Clay makes better high-temp batteries

A unique combination of materials, including a clay-based electrolyte, may solve a problem for rechargeable lithium-ion batteries destined for harsh environments.

The makings of a Hund's metal

In atomic physics, Hund's rules refers to a set of guidelines which are used to determine the term symbol that corresponds to the ground state of a multi-electron atom.

Bullet holes and graphene caves: picturing engineering (w/video)

From a Cambridge guide for robot tourists, to titanium ?comets?, the winners of the annual Department of Engineering photo competition highlight the variety and beauty of engineering.

Sea urchin spurs new ideas for lightweight materials

Materials researchers love sea creatures. Mother-of-pearl provokes ideas for smooth surfaces, clams inspire gluey substances, shark's skin is used to develop materials that reduce drag in water, and so on. Researchers have now found a model for strong, lightweight materials by diving below the sea surface to investigate a sea urchin cousin known as the heart urchin.

Microwave field imaging using diamond and vapor cells

Researchers have developed two new methods for imaging microwave fields. Both methods exploit the change in spin states induced by an applied microwave field.

Hydrogel superglue is 90 percent water

Engineers have developed a method to make synthetic, sticky hydrogel that is more than 90 percent water. The hydrogel, which is a transparent, rubber-like material, can adhere to surfaces such as glass, silicon, ceramics, aluminum, and titanium with a toughness comparable to the bond between tendon and cartilage on bone.
