Nematic liquid crystalline polymers (LCP’s) are interesting anisotropic fluids, which may have some orientational order at rest (molecules tend to align in the same direction). Those polymers may be useful to obtain oriented materials with excellent mechanical, electrical and thermal properties. Its rheological, mechanical and optical properties may be changed by the particle inclusion, depending…
For those who are always looking for new educational tools and to stay up to date, recently I though of sharing with all of you that these days I have learned lots of new things. How was this? I registered in many FREE webinars. What is a webinar??? Webinar is short for Web-based seminar. Is…
The new information delivery service, ACS Mobile, provides readers with an up-to-the-minute live stream of peer-reviewed research content published across the Society’s preeminent portfolio of scholarly research journals, and is augmented by “Latest News†fromChemical and Engineering News (C&EN) –– the Society’s industry-leading magazine and preferred source of online news for its more than 161,000…
There is a great amount of genetic information in the environment. To explore that genetic information can mean the discovery of new drugs like antibiotics; new enzymes for the production of biodegradable fuels, for the enhancement of industrial processes or for the bioremediation of contaminated sites. Direct and indirect approaches have been used to search…
Academic Tenure and Women…… Are we there yet!!! By Darlene I. Santiago Quinones Did you know that 4 out of the 8 prestigious Ivy League Universities in United States are led by Women?????? You might think that finally we have reached equality, well you are incorrect. Do not get me wrong, this is historically and…
A catalyst is a substance which increases the rate of reaction without being consumed appreciably during a reaction process. This write up is focused on Heterogeneous catalysts, which promote the conversion of the reactants, and that are on a different phase than reactants and products. Normally, heterogeneous catalysts are found in solid phase or they…
Many fellowships and sometimes the graduate assistant-ship give you the opportunity to present your research in National and International Conference. Sometimes you don’t know how to find a conference that meets the expectations of your research. It can be hard to find, so allow plenty of time! To help you overcome any difficulties in locating…
Parallel programming began about 30 years ago with the development of mul- tiprocessor computers. Generally, multiprocessor computers have different archi- tectures in terms of the assembly of the processors with their memory. A computer with a shared-memory architecture has multiple processors sharing the same mem- ory modules such that, the processors share the same workspace…
Chemical imaging is an innovative technique that uses conventional imaging and spectroscopy to obtain spatial and spectral information from a sample. Near Infrared Chemical Imaging (NIR-CI) unites the chemical selectivity of vibrational spectroscopy and the potential of image visualization. The combination of both aspects creates a more complete instrument which can be applied for the…
Javier A. Huertas-Miranda and María M. Martínez-Iñesta Through our molecular simulation studies related to the templated synthesis of metal nanowires, we have found that the presence of Al in the zeolite framework has an important influence on the positioning of the guest metal atoms. This is especially important for the MOR framework, which has side…
