Acquiring nanotechnology advancements to march ahead of the race
OMICS Group invites researchers, academicians, scientists, Institutions, corporate entities, associations and students from across the world to attend the Nanotechnology Congress and Expo from 11-13 August 2015, at Frankfurt, Germany with a theme 'Exploring and Acquiring the Advances in Nanotechnology'.
Physicists use nanotechnology to capture perfect colors with one ultra-thin lens
An ultra-thin, completely flat optical component made of a glass substrate and tiny, light-concentrating silicon antennas band light that shines on it instantaneously, rather than gradually.
Direct observation of bond formations (w/video)
Scientists report a real time visualization of the birth of a molecular that occurs via photoinduced formation of a chemical bonds.
New SCENIHR Guidance addresses the health aspects of nanomaterials in medical devices
This Guidance addresses the use of nanomaterials in medical devices and provides information for risk assessors regarding specific aspects that need to be considered in the safety evaluation of nanomaterials.
Potential toxicity of cellulose nanocrystals examined
The latest evidence and insights on cellulose nanocrystal toxicity are presented in a new review article.
Graphene's potential for energy conversion and storage
Scientists working with Europe's Graphene Flagship and the Cambridge Graphene Centre have provided a detailed and wide-ranging review of the potential of graphene and related materials in energy conversion and storage.
Near-perfect antibacterial nanomaterials
Ruthless with bacteria, harmless to human cells. New, durable antibacterial coatings of nanocomposites 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.
Atomically thin gas and chemical sensors
Sensors made of molybdenum disulfide are small, thin and have a high level of selectivity when detecting gases and chemicals.
Microfluidic diamond sensor
Greater magnetic sensitivity is also useful in many scientific areas, such as the identification of biomolecules such as DNA or viruses. This research must often take place in a warm, wet environment, where clean conditions or low temperatures are not possible. Scientists address this concern by developing a diamond sensor that operates in a fluid environment.
Shape-shifting groups of nanorods release heat differently
Researchers have revealed previously unobserved behaviors that show how details of the transfer of heat at the nanoscale cause nanoparticles to change shape in ensembles.
New nanogel for drug delivery
Self-healing gel can be injected into the body and act as a long-term drug depot.
Cheap nanostructured solar cells made with carbon quantum dots from shrimp shells
Researchers have successfully created electricity-generating solar-cells with chemicals found the shells of shrimps and other crustaceans for the first time.
