Essential Science: New cement paste gets stronger when it cracks

Scientists have used 3D printing technology to develop a super-strong form of cement. This is based on the addition of an ingredient that becomes stronger the more pressure that is applied to it.

Super wood material can replace steel

A new process has the potential to transform wood into a material that is as strong as titanium alloys, but one that is also lighter and less expensive.

Triboelectrics: a new form of energy harvesting

Triboelectrics is a new area of science and technology, a field that investigates an alternate form of energy harvesting and a type of self-healing material. One potential is to generate a wave energy; another is with self-healing rubber.

Self-healing rubber invented and triggers business interest

Imagine a tire on a freight vehicle that could heal after being punctured, without the need to call out a breakdown service? This is the technology that has been developed by researchers from the Harvard John A. Paulson School in the U.S.

Advancing flexible electronics through accurate measurements

Coventry - By accurately measuring a range of so-called 'wonder materials', British scientists have taken a step-towards the development of a new generation of flexible electronics.

3D printing’s most stretchable elastomer fashioned

Elastomers are used for a variety of common goods, and they are the basis of flexible electronics. Increasing flexibility while maintaining elasticity is a key requirement; with this, a new super-stretchable elastomer has been developed.

Soybeans hold key to stronger graphene

Graphene is the material of the modern age: strong, light, flexible and highly conductive. It is the basis of a new generation of wearable electronics. To improve the material further, researchers have been looking at the humble soybean.

Tightest material knot ever is achieved

Manchester - Materials scientists have made the most tightly knotted physical structure ever. This feat could lead to a new generation of advanced materials being manufactured.

Researchers turn to sea sponges for building design

Sea sponges seem to be unlikely creatures as to inform us about modern construction, yet researchers have been studying orange puffball sea sponges for inspiration. Of interest is how the sponges avoid buckling under water pressure.

Silkworms that munch on graphene make stronger silk

A new study from China has found that by adding anno-sized fragments of graphene to the diet of silkworms results in the larvae producing stronger and more resilient silk.

Using bones and shells to make super-concrete

Concrete is a strong material, essential for most construction projects. It is, however, prone to cracking over time. Can concrete be made stronger? It seems so by adding bones and shells.

Super alloy bounces back to shape, again and again

Materials scientists have created an alloy that pops back into shape even after it has been bent over 10 million times. The alloy has broken all existing records.

Op-Ed: Physically interactive computing - MIT’s inFORM rewrites CAD, 3D

Sydney - MIT’s new physically interactive inFORM is the at the “Hey, this thing rolls!” stage of wheel invention for practical 3D computing. It’s a 3D physical display of active computer processing- Solid form live computation imagery.

Op-Ed: Welding nano particles with ultrasound breakthrough

Montreal - Ultrasound can generate a lot of heat. Thousands of degrees, in fact. The question has been how to harness it, and that question has now been answered by McGill University Faculty of Dentistry and Medicine.
