An instance of unidentified star jelly on Grimmia pulvinata, a species of moss.. Star jelly (also called astromyxin, astral jelly) is a gelatinous substance sometimes found on grass and less commonly on the branches of trees. [1]
Tovex, a form of water gel explosive. A water-gel explosive is a fuel-sensitized explosive mixture consisting of an aqueous ammonium nitrate solution that acts as the oxidizer. [1] Water gels that are cap-insensitive are referred to under United States safety regulations as blasting agents. Water gel explosives have a jelly-like consistency and ...
The development of napalm was precipitated by the use of jellied gasoline mixtures by the Allied forces during World War II. [5] Latex, used in these early forms of incendiary devices, became scarce, since natural rubber was almost impossible to obtain after the Japanese army captured the rubber plantations in Malaya, Indonesia, Vietnam, and Thailand.
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay), and stabilizers. [1] It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867.
An upturned vial of hair gel Silica gel. A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. [1] [2] Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady state, although the liquid phase may still diffuse through this system.
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
Vyacheslav Molotov, 1945. The name "Molotov cocktail" (Finnish: Molotovin cocktail) was coined by the Finns during the Winter War in 1939.[10] [11] [12] The name was a pejorative reference to Soviet foreign minister Vyacheslav Molotov, who was one of the architects of the Molotov–Ribbentrop Pact on the eve of World War II.
GelRed is an intercalating nucleic acid stain used in molecular genetics for agarose gel DNA electrophoresis. GelRed structurally consists of two ethidium subunits that are bridged by a linear oxygenated spacer. [1] [2] GelRed is a fluorophore, and its optical properties are essentially identical to those of ethidium bromide.
