Nanoscale worms provide new route to nano-necklace structures

Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.

Novel nanoparticle therapy promotes wound healing

An experimental therapy developed by researchers at Albert Einstein College of Medicine of Yeshiva University cut in half the time it takes to heal wounds compared to no treatment at all. Details of the therapy, which was successfully tested in mice, were published online in the Journal of Investigative Dermatology.

Chemists make new silicon-based nanomaterials

In a paper published in the journal Nanoletters, the researchers describe methods for making nanoribbons and nanoplates from a compound called silicon telluride. The materials are pure, p-type semiconductors (positive charge carriers) that could be used in a variety of electronic and optical devices. Their layered structure can take up lithium and magnesium, meaning it could also be used to make electrodes in those types of batteries.

"Silicon-based compounds are the backbone of modern electronics processing," said Kristie Koski, assistant professor of chemistry at Brown, who led the work. "Silicon telluride is in that family of compounds, and we've shown a totally new method for using it to make layered, two-dimensional nanomaterials."

How green tea could help improve MRIs

Green tea's popularity has grown quickly in recent years. Its fans can drink it, enjoy its flavor in their ice cream and slather it on their skin with lotions infused with it. Now, the tea could have a new, unexpected role — to improve the image quality of MRIs. Scientists report in the journal ACS Applied Materials & Interfaces that they successfully used compounds from green tea to help image cancer tumors in mice.

Nanotechnology Enabled Drug Delivery to Influence Future Diagnosis and Treatments of Diseases

Diagnosis and drug delivery for diseases like cancer, cardiovascular and genetic ailments has always been a concern. In recent years, however, new strides and developments in the nano-medicine market have facilitated more effective diagnosis and drug delivery for diseases. Not only can these diseases now be studied better but it will also help us in making informed decisions producing better cures. The nano-medicine market is on a steady growth and with a compound annual growth rate (CAGR) of 12.5% from 2011; the market size will reach to $130.9 billion by 2016.

Nanotechnologies in Drug Delivery Congress organized by Markets and Markets Conferences is gathering industry experts from the nano-medicine market who will look at these developments and also present new ideas. Supported by the French Society for Nanomedicine, the congress will be held on 27 - 28 April 2015 in London, UK. Speaking at the congress will be AstraZeneca, Nemaura Pharma, Lloyds Register Quality Assurance, Cytoviva, World Nano Foundation, King's College London, Institute for Biological and Medical Imaging, Uppsala University and University of Oxford among others.

First proof of isolated attosecond pulse generation at the carbon K-edge

In a recent study, "Spatiotemporal isolation of attosecond pulses in the soft X-ray water window " published in Nature Communications by the Attoscience and Ultrafast Optics Group, led by ICREA Professor at ICFO Jens Biegert, the generation of isolated attosecond pulses at the carbon K-edge at 284 eV (4.4 nm), within the water window range, was achieved.
