Before coring, porewater from each core site was collected using a perforated stainless-steel tubing inserted into the peat to the desired depth and extracted with an airtight syringe. No pore water was collected in the dry palsa or above the water table in the bog. Porewater was used to ...
steel was encountered it would cut through the sword blades that the Europeans were using. This is reportedly because the material was the perfect mixture of tough steel and hard steel. In the Middle East this type of steel had been made for thousands of years, but the knowledge of how to...

Because the composition and construction of a tantalum-MnO2 capacitor is similar to that of a firecracker (a finely divided metal in intimate mixture with a substance that releases oxygen when heated) these capacitors are well-known for failing in pyrotechnic fashion, characterized by explosions and/...
; moreover, biofilms are of great concern in a variety of human diseases such as listeriosis (Listeria monocytogenes), endocarditis (Enterococcus faecalis) and cystic fibrosis (P. aeruginosa)8,9. An antibiotic is generally defined to be a substance produced by one microorganism that selectively ...

Under natural environmental conditions, biofilms are likely to be composed of a mixture of different species[131,132]. In the laboratory, they can be grown on various materials and devices, including polystyrene microtitre plates[133-136], haemolysis glass tubes[137,138], stainless steel coupons...
From a strict toxicological point of view, there can be no such thing as an inherently safe chemical, as literally every substance, including water, will cause harm if present at the right dose in a particular organ or environment (“All things are poison…”). The key to any effective (...
The crystalline substance found in most disposable diapers is sodium polyacrylate, a chemical absorbent used in the super absorbent layer. Sodium polyacrylate can absorb 200 to 300 times its weight in tap water, transforming it into a gooey gel to keep the diaper surface dry. While sodium polyacr...
