Surprise as electric fields found to cleave bond homolytically

Researchers in the US have performed an electric field-driven chemical reaction in bulk solution. It is the first study to quantify chemical rate enhancement by an external electric field and paves the way for chemical reactions that no longer require chemical reagents or harsh conditions to drive them. Electric field-driven chemical reactions are a promising […]

Renaissance Science – L

The so-called scientific revolution in the seventeenth century is often characterised as throwing off the yoke of Aristotelian philosophy that had held the scholastic medieval university in a strangle hold since Albertus Magnus (c. 1200–1280) had made it compatible with Catholic doctrine in the thirteenth century. In reality rather than being thrown off, on the […]

Locked degradability breaks plastic paradox

Mechanical activation converts a strong new polymer into an alternative chemical form that more easily degrades into simple monomer units. The idea could offer a way to regenerate valuable chemical feedstocks from discarded plastics. Plastics are ubiquitous in modern life. Their chemical inertness and durability make them ideally suited to thousands of diverse applications, but […]

Contaminated cough syrups death toll passes 300 in four months

A string of deadly incidents connected to contaminated and substandard medicines have emerged in recent months. Cough syrups contaminated with ethylene glycol (EG) and diethylene glycol (DEG) have led to deaths of 70 children in The Gambia, more than 200 in Indonesia, and – most recently – 19 in Uzbekistan. Meanwhile in the US, eye […]

Metal–carbon catalysts made from plants can break down plastics

Plants grown in nickel-contaminated soils have been made into catalysts that break down difficult-to-recycle plastics. Polyethylene makes up 36% of all plastics and is resistant to high temperatures and pressure, mechanical force and chemical corrosion. These properties, while making polyethylene a useful material, mean this common plastic is very difficult to break down for recycling. […]

Leonardo and gravity

Mory Gharib an engineer from Caltech has published an article about his interpretation of some diagrams he discovered in one of the Leonardo manuscripts, which he claims are Leonardo’s attempts to determine the acceleration due to gravity. I’m not going to comment on Gharib’s work, which looks interesting, but rather on the article published in […]
