Penn researchers develop new technique for making molybdenum disulfide
University of Pennsylvania researchers have made an advance in manufacturing molybdenum disulphide, a 2-D material that could compete with graphene for replacing silicon in next-generation electronics. By growing flakes of the material around 'seeds' of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.

Bar-Ilan U. researcher first to observe 'god particle' analogue in superconductors
The Nobel Prize-winning discovery of the Higgs boson -- the 'God particle' believed responsible for all the mass in the universe -- took place in 2012 at CERN's Large Hadron Collider. The first hint of Higgs was inspired by the study of superconductors -- a special class of metals that, when cooled to very low temperatures, allow electrons to move without resistance. Now, a research team led by Israeli and German physicists has reported the first-ever observations of the Higgs mode in superconducting materials.

Near-perfect antibacterial materials
Ruthless with bacteria, harmless to human cells. New, durable antibacterial coatings of nanocomposites, developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, will in future help to improve the hygiene of sportswear, and used in medicine, will reduce the rate of infections and shorten the times of in-patient hospital admissions.

Monitoring the real-time deformation of carbon nanocoils under axial loading
Tensile tests were performed on nine carbon nanocoils using a focused-ion-beam technique. An individual CNC was picked up using -- an FIB, and a CNC bridge formed between a probe and the spring-table?substrate. Real-time observations of the CNC elongation and subsequent -- fracture under prolonged stretching enabled us to estimate the elastic -- limit, the spring constant, the shear modulus, and the ultimate strength -- of each CNC and their mean values.

Keeping atherosclerosis in-check with novel targeted inflammation-resolving nanomedicines
Nanometer-sized 'drones' that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis, according to a study in pre-clinical models by scientists at Brigham and Women's Hospital and Columbia University Medical Center. These findings are published in the Feb. 18 online issue of Science Translational Medicine.

A novel approach for high performance field emission electron sources
Enhancing the electron emission of multi-wall carbon nanotubes (MWCNT) is key for applications ranging from cold cathodes used in high-resolution electron microscopes to portable X-ray imaging systems. In a paper recently published in Nanotechnology, a team led by professor My Ali El Khakani, from the Energie Matériaux Télécommunications Research Centre of INRS, has reported an original approach for the development of novel graphenated-MWCNTs with enhanced field electron emission properties.

Making teeth tough: Beavers show way to improve our enamel
Beavers don't brush their teeth or drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.
