<span class="mw-page-title-main">Emil von Behring</span> German physiologist (1854–1917)

Emil von Behring, born Emil Adolf Behring, was a German physiologist who received the 1901 Nobel Prize in Physiology or Medicine, the first one awarded in that field, for his discovery of a diphtheria antitoxin. He was widely known as a "saviour of children", as diphtheria used to be a major cause of child death. His work with the disease, as well as tetanus, has come to bring him most of his fame and acknowledgment. He was honoured with Prussian nobility in 1901, henceforth being known by the surname "von Behring."

Søren Peter Lauritz Sørensen was a Danish chemist, known for the introduction of the concept of pH, a scale for measuring acidity and alkalinity.

<span class="mw-page-title-main">Cystine</span> Chemical compound

Cystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH2CH(NH2)CO2H)2. It is a white solid that is poorly soluble in water. As a residue in proteins, cystine serves two functions: a site of redox reactions and a mechanical linkage that allows proteins to retain their three-dimensional structure.

Richard Adolf Zsigmondy was an Austrian-born chemist. He was known for his research in colloids, for which he was awarded the Nobel Prize in chemistry in 1925, as well as for co-inventing the slit-ultramicroscope, and different membrane filters. The crater Zsigmondy on the Moon is named in his honour.

<span class="mw-page-title-main">Richard Hornsby & Sons</span> Engine and machinery manufacturer in Grantham, Lincolnshire, England from 1828 until 1918

Richard Hornsby & Sons was an engine and machinery manufacturer in Grantham, Lincolnshire, England from 1828 until 1918. The company was a pioneer in the manufacture of the oil engine developed by Herbert Akroyd Stuart, which was marketed under the Hornsby-Akroyd name. The company developed an early track system for vehicles, selling the patent to Holt & Co. in America. In 1918, Richard Hornsby & Sons became a subsidiary of the neighbouring engineering firm Rustons of Lincoln, to create Ruston & Hornsby.

Curt Theodor Schimmelbusch was a German physician and pathologist who invented the Schimmelbusch mask, for the safe delivery of anaesthetics to surgical patients. He was also a key figure in the development of mechanical methods of sterilisation and disinfection for surgical procedures, on which his Anleitung zur aseptischen Wundbehandlung was considered a seminal work.

Johannes Adolf von Kries was a German physiological psychologist who formulated the modern “duplicity” or “duplexity” theory of vision mediated by rod cells at low light levels and three types of cone cells at higher light levels. He made important contributions in the field of haemodynamics. In addition, von Kries was a significant theorist of the foundations of probability.

Wilhelm Heinrich Heintz was a German structural chemist from Berlin.

<span class="mw-page-title-main">Nikolai Menshutkin</span> Russian chemist

Nikolai Aleksandrovich Menshutkin was a Russian chemist who discovered the process of converting a tertiary amine to a quaternary ammonium salt via the reaction with an alkyl halide, now known as the Menshutkin reaction.

The Gibbs–Thomson effect, in common physics usage, refers to variations in vapor pressure or chemical potential across a curved surface or interface. The existence of a positive interfacial energy will increase the energy required to form small particles with high curvature, and these particles will exhibit an increased vapor pressure. See Ostwald–Freundlich equation. More specifically, the Gibbs–Thomson effect refers to the observation that small crystals are in equilibrium with their liquid melt at a lower temperature than large crystals. In cases of confined geometry, such as liquids contained within porous media, this leads to a depression in the freezing point / melting point that is inversely proportional to the pore size, as given by the Gibbs–Thomson equation.
