Nanoscale Editorial Board member Molly Stevens (Imperial College London) gave a talk at the Annual Biophysical Society meeting yesterday.
This was the first time Professor Stevens had been invited to talk at the Biophysical Society Meeting, and her lecture on her research into tissue engineering was very well received. Her research focusses on the regeneration of tissue, with a focus on engineering new bone tissue.
She also discussed her collaborative research on sub-nanoscale patterning which she did with Francesco Stellacci’s group (Nanoscale Editor-in-Chief) – find out more about Nanoscale and our Editorial Board at www.rsc.org/nanoscale
The Chinese State Council announced yesterday that they have appointed Chunli Bai as the next president of the Chinese Academy of Sciences (CAS).
Professor Bai has been the executive vice president of CAS since 2004, and will take over from former CAS President Lu Yongxiang.
The Nanoscale team would like to congratulate Professor Bai and we wish him all the best in his new role!
A simple, scalable, graphene patterning method has been developed and applied to fabricate CdSe nanobelt/graphene Schottky junction solar cells. A typical as-fabricated solar cell shows an energy conversion efficiency of ~1.25%.

Carbon nanotubes can enhance plant growth without damaging plant cells, say scientists from India
Sabyasachi Sarkar and colleagues from the Indian Institute of Technology in Kanpur treated chickpea plants with up to 6ug/ml of water soluble carbon nanotubes. They found that the nanotubes increased the growth rate in every part of the plant – in the roots, shoots and branches.
Sarkar thought that the channels could be replicated by carbon nanotubes. ‘We followed Thomas Edison’s recipe to make carbonised filament from bamboo or wood wool in his electric bulb to get the carbon nanotubes,‘ he adds. ‘Of course, we had to derivatise them to make them water soluble.’ The team achieved this by attaching carboxylic acid groups to the surface of the tubes.
‘The work seems to support the positive effect of carbon nanotubes,’ says Xiaohong Fang, an expert in the use of carbon nanotubes as molecular transporters in plants at the Chinese Academy of Sciences in China. However, she points out that the biological effects on plants may differ depending on the materials’ chemical and physical properties, plant type and cultivation conditions.

Inspired by nature, a variety of metallic surfaces with special wettability have been fabricated in recent years.
They exhibit important applications in anti-corrosion, microfluidic systems, oil–water separation, liquid transportation, and could be expanded into other fields such engineering, biomedicine, and materials science.
The present study demonstrates an eco-friendly and low cost protocol for silver nanoparticles synthesis using cell-free filtrate of Aspergillus flavus.

Can street lights be replaced by trees? Taiwanese scientists believe that they can using gold nanoparticles to induce luminescence in leaves.
Yen Hsun Su and coworkers at Academia Sinica and the National Cheng Kung University in Taipei and Tainan have tackled this problem by synthesising gold nanoparticles shaped like sea urchins and diffusing them into plant leaves to create bio-LEDs.
