How efficient can solar cells be? UNSW nudges closer to physical limits
A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5 percent -- establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device.

Combining nanotextured surfaces with the Leidenfrost effect for extreme water repellency
Combining superhydrophobic surfaces with Leidenfrost levitation -- picture a water droplet hovering over a hot surface rather than making physical contact with it -- has been explored extensively for the past decade by researchers hoping to uncover the holy grail of water-repellent surfaces. In a new twist, a group of South Korean researchers report an anomalous water droplet-bouncing phenomenon generated by Leidenfrost levitation on nanotextured surfaces in Applied Physics Letters.

At attention, molecules!
University of Iowa chemists have learned about a molecular assembly that may help create quicker, more responsive touch screens, among other applications. The researchers report the interfacial layer -- when molecules interact with a surface -- of electrically charged fluids called ionic liquids is thicker than previously known. Results appear in the journal Langmuir.

Unveiling the electron's motion in a carbon nanocoil
Toyohashi Tech researchers, in cooperation with researchers at University of Yamanashi, National Institute of Technology, Gifu College, and Tokai Carbon Co., Ltd., have? discovered how the electrical resistivity of carbon nanocoils (CNCs) depends on their geometry. The finding, which required development of a new resistivity measuring apparatus, paves the way for CNC-based nanodevices ranging from electromagnetic wave absorbers to nano-solenoids and extra-sensitive mechanical springs.

This 'nanocavity' may improve ultrathin solar panels, video cameras and more
Recently, engineers placed a single layer of MoS2 molecules on top of a photonic structure called an optical nanocavity made of aluminum oxide and aluminum. The results are promising. The MoS2 nanocavity can increase the amount of light that ultrathin semiconducting materials absorb. In turn, this could help industry to continue manufacturing more powerful, efficient and flexible electronic devices.

A better hologram for fraud protection and wearable optics
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have programmed polarization into compact holograms. These holograms use nanostructures that are sensitive to polarization (the direction in which light vibrates) to produce different images depending on the polarization of incident light. This advancement, which works across the spectrum of light, could lead to improvements in anti-fraud holograms as well as those used in entertainment displays.

Innovative graphene technology to buffer the activity of synapses-- this is the idea behind a recently-published study in the journal ACS Nano coordinated by the International School for Advanced Studies in Trieste and the University of Trieste. In particular, the study showed how effective graphene oxide flakes are at interfering with excitatory synapses, an effect that could prove useful in new treatments for diseases like epilepsy

Performing cellular surgery with a laser-powered nanoblade
To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but researchers reporting May 10 in Cell Metabolism describe a 'nanoblade' that can slice through a cell's membrane to insert mitochondria. The researchers have previously used this technology to transfer other materials between cells and hope to commercialize the nanoblade for wider use in bioengineering.

Common nanoparticle has subtle effects on oxidative stress genes
A nanoparticle commonly used in food, cosmetics, sunscreen and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells. While the titanium dioxide nanoparticles are considered non-toxic because they don't kill cells at low concentrations, these cellular effects could add to concerns about long-term exposure to the nanomaterial.

Novel functionalized nanomaterials for CO2 capture
Climate change due to excessive CO2 levels is one of the most serious problems mankind has ever faced. CO2 emissions need to be reduced urgently to avoid potentially dangerous and irreversible effects of climate change. To mitigate such emissions, CO2 capture is one of the best solutions. Scientists at the Tata Institute of Fundamental Research, Mumbai, have developed novel functionalized nanomaterials that can capture CO2 with superior capture capacity and stability over conventional sorbents.
