Tri-layer silicene may beat bulk GaAs as high-efficiency photovoltaic absorber

siliceneIn the past few years, monolayer and multilayer silicenes have been successfully grown on various metal substrates. Unfortunately, silicene on metal substrate generally exhibits metallic or semi-metallic character without a bandgap, and thus cannot be used as adsorption layer of photovoltaic materials. A new comprehensive investigation of multilayer silicene by means of ab initio swarm-intelligence structure-searching method...

Beware the fake graphene

grapheneA new study on worldwide graphene production shows unequivocally that the quality of the graphene produced in the world today is rather poor, not optimal for most applications, and most companies are producing graphite microplatelets. This is possibly the main reason for the slow development of graphene applications, which usually require a customized solution in terms of graphene properties. A conclusion that sounds even...

Nanoradiators allow precise optical manipulation of nanoparticles (w/video)

nanoradiatorResearchers have developed a new type of optical manipulation method to achieve versatile manipulation of objects with different sizes and types using optical heating. In this new technique, nanoparticles get trapped at temperature hot spots instead of electrical hot spots, which demonstrates a different working mechanism and approach from the traditional optical manipulation techniques. Due to this unique working principle,...

Nanotechnology based drug delivery systems for nanomedicine

nanococoonDevelopment of an effective approach for delivering a new drug is as important as inventing a new drug. Even if a developed new drug has excellent pharmacokinetic and therapeutic properties, it shows its potential activity in the body effectively only when it is exactly targeted to specific molecules. Various nanotechnological approaches for effective drug delivery have been developed and some of them have already been successfully...

2D material produces highest ever signals for human embryonic stem cell detection

stem-cellsResearchers have developed a way to achieve an ultra-high bioelectric signal from human embryonic stem cells using direct current-voltage measurements facilitated by few-layered 2D molybdenum disulfide sheets. This method, which produces cell signals 2 orders of magnitude higher than previous electrical-based detection methods, paves the way for the development of a broadly applicable, fast, and damage-free stem cell detection...

The rise of phosphorene analogue optoelectronic materials

phosphoreneBlack phosphorus (BP or phosphorene), a novel two-dimensional semiconducting material, has gained tremendous attention because of its intriguing properties, such as ON/OFF ratio, high carrier mobility, and tunable direct band. However, a fundamental obstacle hindering practical applications is the lack of stability under ambient conditions. Now researchers demonstrated both excellent photoelectrochemical performance and significantly...
