Efficiency record for black silicon solar cells jumps to 22.1 percent: Aalto University's researchers improved their previous record by over 3 absolute percents in cooperation with Universitat Politècnica de Catalunya
The surface area of the best cells in the study was already 9 cm2. This is a good starting point for upscaling the results to full wafers and all the way to the industrial scale.

Random nanowire configurations increase conductivity over heavily ordered configurations
Sample networks of Ag nanowires for 140?μm × 140?μm domain with (a) concentration just above critical percolation concentration (C?~?Cp), and (b) concentration much above critical percolation concentration (C»Cp). The voltage is applied across the horizontal direction across the domain length.

Quantum physics on tap - Nano-sized faucet offers experimental support for longstanding quantum theory
This schematic drawing shows a nanoscale faucet: a long cylindrical channel connected to a container of superfluid helium. When vacuum pressure is applied to one end of the faucet's opening-a nanopore-helium atoms (represented here as pink balls) flow through, and are collected and measured as they spread out. An incredibly sensitive detector is needed to register the hundredths of nanograms of helium that flow through each second.

Science and Technology of Advanced Materials (STAM): Reported successes and failures aid hot pursuit of superconductivity
Gold rush at the initial stage of iron-based superconductors.
High Tc iron-based superconductor was reported in January 2008 via the discovery of iron- and nickel-based superconductors in 2006-2007. Half a year since then was just a dog year, i.e., the maximal Tc was pushed up to ~55K, the major parents compounds were found, and new carrier doping method ( Co substitution of Fe sites) and epitaxial thin film growth were reported. Note the received date in the figure denotes day that the submitted manuscript was received at the journal office or the manuscript was posted on ArXiv web server.
