2:41 PM | An objection to tattoos
From this week's C&EN, an unhappy letter writer: The profile of tattooed “chemistry ambassador” Randa Roland is beneath the level of your magazine’s aspirations (C&EN, Jan. 19, page 30). First, Roland errs in describing Fritz Haber as “trying to do good” and succeeding when he developed the Haber process during World War I. Haber was explicitly trying to convert elementary nitrogen chemically to ammonia to be used in synthesizing explosives in the […]

1:07 PM | A quick and simple blood test to detect early-stage cancer
A novel nanoparticle blood test detects an overall increase of human immunoglobulin G (IgG), including the tumor-specific autoantibodies, adsorbed to a gold nanoparticle surface. While this test may not be able to identify the specific type of cancer, it may potentially be able to detect early stage tumor-induced immune responses associated with a broad spectrum of cancer types, making this test potentially a universal screening test for cancer risk assessment.

9:20 AM | Uses of Ammonium Chloride
Ammonium Chloride is a clear white crystal which readily dissolves in water. It occurs naturally in some volcanic regions of the world. Commercial manufacture of Ammonium Chloride involves reacting Ammonia with Hydrogen Chloride. Ammonium Chloride has a chemical formulation NH4Cl and Ammonium Chloride is sometimes known as ‘sal ammoniac’. You can order ammonium chloride from [...]

9:42 PM | Zinc Lozenges Soothe Cold Symptoms
Click info-graphic to enlargeWinter is coming to an end and last Friday was officially the first day of spring  (but if you're in England you probably didn't notice a difference; maybe the odd daffodil here and there but the weather is pretty much the same). So with the changes in weather comes cold & flu season, where it seems as if everyone's got a cold, and taking sick-days off school/work. Two scientists at the university of Helsinki studies the effects of zinc […]

7:41 PM | Pauling vs Woodward: It's on
Some day they will hopefully make a video about this along the lines of Einstein vs Hawking or Hayek vs Keynes. For now an imperfect beginning will have to suffice (with apologies to Gilbert and Sullivan, of course. Oh, and Tom Lehrer too).Pauling:I am the very model of the greatest chemist ever...I've information vegetable, animal, and mineral,I know the bonds of aluminum, and I quote the distances dihedral,From quantum to quark, in order categorical;I'm very well acquainted too with matters […]

4:17 PM | New technique could bring quality-control tool for nanocomposites
Layered nanocomposites containing tiny structures mixed into a polymer matrix are gaining commercial use, but their complex nature can hide defects that affect performance. Now researchers have developed a system capable of detecting such defects using a Kelvin probe scanning method with an atomic force microscope.

3:40 PM | Your morning Food Babe troll
Courtesy of @UnstableIsotope, Food Babe lets her chemophobe flag fly:For several years, I’ve started my day with warm lemon water and cayenne pepper. Lemon water is very alkaline and can stimulate the liver. It can change your taste buds so you don’t crave sugary foods, and instead crave alkaline ones like fruits and vegetables. The cayenne pepper has been proven to boost your metabolism. But both of those ingredients together strengthen the immune system. I’ve gotten fewer […]

3:03 PM | Plastics Recycling - Good News and Bad News
A couple of recent online reports highlight the "interesting" times that plastics recycling faces. (By "interesting", I'm referring to the infamous non-Chinese, Chinese curse of living in interesting times.)First, the good news: The American Chemistry Council is reporting that the recycling rates for plastic films took a nice jump up last year of over 11%. The research organization that performed the study "attributes the gain to a combination of increased collection and more comprehensive […]

2:36 PM | Platinum Investment Casting, Part I: Simulation and Experimental Study of the Casting Process
This paper summarises the results of collaborative research on investment casting of widely used platinum alloys (platinum with 5 wt% ruthenium (Pt-5Ru) and platinum with 5 wt% cobalt (Pt-5Co)) for jewellery purposes. To enable the simulation of the casting process, a materials database was developed as a first step. Casting simulation tools based on computational fluid dynamics (CFD) were used to optimise the casting process parameters and develop an improved understanding of their role. […]

2:15 PM | Imagine you’ve got 5 masses connected to each other by...
Imagine you’ve got 5 masses connected to each other by springs and subjected to Brownian thermal perturbation, wobbling around, what is the probability distribution of their displacements y1 from y5? Well, you can work it out, and their inverse covariance matrix (K-1) is to do with who’s connected by springs. Each term in the energy gives you terms in this matrix, describing the couplings between these displacements: so the inverse covariance matrix is very sparse, very […]
