Today I visited my mother and as she was preparing lunch she asked me if I would like iodized or regular table salt in my soup. I went with the regular one because I never feel quite comfortable when there are artificial additives in my food. I guess it is because I have a hard […]

This synopsis was written by Rachel Jones on a very interesting research work: “Mental Training Affects Distribution of Limited Brain Resources” by Richard J. Davidson and his team where their findings demonstrate that meditative training can improve performance on a novel task that requires the trained attentional abilities. So those who learn and study can […]

The researches inadvertently discovered that they can write and erase on the surface of liquids – the method that could one day be applied to high-density data storage, making templates for etching silicon chips (photolithography) and a variety of other materials applications. Peter Licence at the University of Nottingham, UK, and his colleagues were using […]

Almost two weeks ago there was a question regarding Nano HPLC technology that I attempted to answer and in that post I mentioned Agilent as one of the pioneers in the Nano LC field. Agilent’s “nano” workhorse is a 1200 Series HPLC-Chip/MS system, which uses microfluidics chip-based technology for nanospray LC/MS. Based on the HPLC-Chip […]

Assistant professor Juan Hinestroza and postdoctoral researcher Hong Dong from Cornell University created two types of fabric: one can prevent colds and flu and never needs washing, and another that destroys harmful gases and protects the wearer from smog and air pollution. The “super” fabric is made by coating ordinary cotton with silver nanoparticles. First […]

This is another Q&A from Yahoo! Answers which I could not stay away from. The question was asked by “pigpigletpoker” and has already received two answers. Dave_Stark said: Make a chromatogram of the paint found on the other car involved in the accident. Then do a side-by-side chromatogram of the red paint from the two […]

This question was asked today by “Rambabu26 d” and it has been answered by three chromatography wizards. Bullfrog21, who gave a short but precise answer: Peak width is the distance on the graph between the two lowest points on either side of the peak. […] A second answer came from, T0bl3rone who assumed that the […]

Here is another example of forensic application of HPLC that allows to classify and date the black gel pen ink entries on documents. Gel pens first came out in 1984 in Japan and quickly became popular throughout the world due to their solid line, bold colors, and low cost. They are also regarded as environmentally […]

Forensic analysis of inks by imaging desorption electrospray ionization (DESI) mass spectrometry

Researchers at Cornell University have created a so-called Nano-Lamp â?? a microscopic collection of light-emitting fibers with dimensions of only a few hundred nanometers. The fibers are made of a polymer spiked with ruthenium molecules in a process dubbed ‘electrospinning
