Vaccines are complex biomedicines composed of a number of different molecules. In the manufacturing process and before marketing authorisation, extensive research is required to verify the identity, quality, efficacy and safety of the products. Fast, cost-effective yet reliable analytical methods ...
Nanoparticles with a wide range of applying, including medicine, damage cells of microalgae Heterosigma akashivo badly. This algae species is widely spread in the Russian Far East marine area. The acute toxic effect exhibited at concentrations of 100 mg/l of carbon nanotubes (CNTs) and silicon ...
A recent study, affiliated with UNIST has measured and controlled the temperature of individual graphene bubbles with a single laser beam for the first time. Thisstudy has been led by DistinguishedProfessorRodney S. Ruoff (School of Natural Science) in collaboration with Distinguished ...
A new way of organizing nanostructures has boosted Raman signals by a hundred thousand times to better identify and characterize different molecules
As medicine and pharmacology investigate nanoscale processes, it has become increasingly important to identify and characterize different molecules. Raman spectroscopy, a technique that leverages the scattering of laser light to identify molecules, has a limited capacity to detect molecules in ...
Spectral fingerprint allows control of function
Two-dimensional graphene consists of single layers of carbon atoms and exhibits intriguing properties. The transparent material conducts electricity and heat extremely well. It is at the same time flexible and solid. Additionally, the electrical conductivity can be continuously varied between a ...
Cavity-enhanced Raman-scattering reveals information on structure and properties of carbon nanotubes
Carbon nanotubes can be produced with a variety of shapes and properties and are therefore of much interest for widespread applications in fields as diverse as electronics, photonics, nanomechanics, and quantum optics. Hence it is important to have a tool at hand that allows to determine these ...
Researchers present a direct first proof of stable ultra-long 1D carbon chains
Elemental carbon appears in many different modifications, including diamond, fullerenes and graphene. Their unique structural, electronic, mechanical, transport and optical properties have a broad range of applications in physics, chemistry and materials science, including composite materials, ...
Elements and their compounds will no longer be able to hide in mixtures, even if the latter are made up of many components. The end of chemical incognito is a result of the development at Warsaw's Polish Academy of Science's Institute of Physical Chemistry of a new, much more accurate method of ...
