…well, the prescription ones at least. With Chinese manufacturers considering to increase exports of drug ingredients and perhaps even begin shipping finished drug products to the United States, an article “Trusting medicine from China: Close FDA scrutiny of Chinese pharmaceutical ingredients extends only to those for prescription drugs” in Chemical & Engineering News (C&EN) questions […]

It is interesting to note that 20 years later there is still no clear definition of nano-LC. Due to a relatively large size of the columns used in nano-HPLC (10-140 μm), the method does not fall within the realm of the conventional definition of nanotechnology – “the control of matter on a scale smaller than […]

Thanks to one of the readers of this blog – Farooq, I now have the full text of an excellent, 21-page review by the researches from Rome and Spain entitled “Recent applications in nanoliquid chromatography” (DOI 10.1002/jssc.200700061). Two months ago, I did a small article about nano liquid chromatography to answer a question posted on […]

This is the next post from the series dedicated to 135th birthday anniversary of Prof. Tsvet, the chromatography’s founder. Today, the application of the principle of a chromatographic substance separation is the foundation of many breakthroughs in science and technology. The analysis of the amino acid and nucleotide sequence in proteins and nucleic acids, the […]

New research on sulfate-reducing bacteria may offer good news for bioremediation efforts to clean up acid mine drainages and other environments with high levels of harmful metals. Sulfate-reducing bacteria is known to extract metal dissolved in anoxic waters and by isolating it into nanoscale particles. But, the tiny size of these particles (2-6 nm) makes […]

A chromium catalyst is the key to efficiently converting glucose to a chemical feedstock with potential to replace many uses of crude oil including pharmaceuticals, cosmetics and plastics, scientists from Pacific Northwest National Laboratory report. As the world tries to emancipate itself from its oil addiction, researchers are seeking a clean, efficient and cost effective […]

A simple, cheap treatment using just oxygen could allow organic produce growers to store their crops for longer and go a long way towards reducing the price of organic fruit and vegetables. I admit that I am into organic produce but mostly because it tastes better and fresher than the conventionally grown fruits and vegetables […]

Today, it has been 3 years since I recovered from Rocky Mountain Spotted Fever or RMSF – a disease caused by Rickettsia rickettsii, a species of bacteria that is spread by hard ticks. On one hand, it is kind of cool that I had contracted a relatively rare and almost exotic disease (only ~800 reported […]

Today I received an e-mail from an unhappy reader where I am being mercilessly criticized for misleading the visitors to my blog. Mr. X is rightfully accusing me for not staying focused on the topic of “just chromatography” and that I spend too much time on nanotechnology and things like witricity. What can I say […]

A month ago I wrote a post “World Without Wires” about the unique material developed by Japanese scientists that can transmit electrical energy to nearby devices without the need for direct contact. Now in today’s issue of Science magazine, an MIT research team led by Prof. Marin Soljacic reported its version of the “world without […]
