STATINA uses vibration to enable information interaction on solid flat surfaces

By Damir Beciri
One Comment22 July 2013

statina-1We already wrote about various new ways for information interaction, and a group of researchers at the Nanyang Technological University (NTU) developed a low cost system which allows conversion of virtually any flat solid surface around us into a touch sensitive surface. The system relies on the principles of vibration and imaging, and it is… »

Graphene ‘onion rings’ – creating graphene nanoribbons atom by atom

By Damir Beciri
20 July 2013

onion-carbon-nanoribbons-1Experiments at Rice University meant to reveal how graphene grows under high pressure and in a hydrogen-rich environment resulted up with development of concentric hexagons of graphene. The process represents the first time anyone has synthesized graphene nanoribbons atom by atom on metal. Once perfected, the approach could lead to breakthroughs in electronics lithium ion… »

Advancement in complex 3D polymer brush nanostructures creation

By Damir Beciri
14 July 2013

photomasks-used-to-craete-complex-3d-polymer-brushes-1Polymer brushes are polymers in which individual polymer chains stand side by side on a surface, causing the chains to stick out like bristles on a brush. A team of researchers at the University of California, Santa Barbara, and The Dow Chemical Company (Midland, Michigan) have developed a new method that allows creation these three-dimensional… »

One Comment11 July 2013

5d-data-storage-1Using nanostructured glass, researchers at the University of Southampton have experimentally demonstrated the recording and retrieval processes of five dimensional digital data by femtosecond laser writing. Dubbed as the ‘Superman’ memory crystal’, since the glass memory has been compared to the “memory crystals” used in the Superman movies, a disc can store 360 TB of… »

Novel advancements in hydrogels

By Maja Bosanac
9 July 2013

hydrogel-double-network-1Hydrogels are gelatinous substances with several biomedical applications, including cartilage repair, implants for minimally invasive surgery and drug delivery. Most hydrogels are weak, brittle, and of low mechanical strength. They also exhibit limited extensibility, recoverability, and poor toughness. On the other hand, double-network hydrogels exhibit high mechanical strength, excellent recoverable properties, and a unique, free-shapeable… »
