Joseph William Mellor
Joseph William Mellor (1868–1938) was an English chemist and an authority on ceramics who grew up in New Zealand. Early life Joseph William Mellor was born in Lindley, Huddersfield, England, in 1869. He moved to New Zealand with his family in 1879 and settled in Kaiapoi, where he attended Kaiapoi School. During his two years in Canterbury, he worked at the Kaiapoi Woollen Company. The family moved to Dunedin in 1881 where he went to Linden School in the suburb of Kaikorai Valley. The family was too poor to send Joseph to secondary school, but he continued to study in his spare time and undertook self-initiated study at King Edward Technical College. Mellor graduated from the University of Otago in 1898. He won a scholarship to study for a research degree at the University of Manchester. Career in the UK Mellor never returned to New Zealand, although he kept in contact with relatives there and represented the country as a governor of Imperial College, London. After his thre ...

University Of The Third Age
The University of the Third Age (U3A) is an international movement whose aims are the education and stimulation of mainly retired members of the community—those in their third 'age' of life. There is no universally accepted model for the U3A. Its original conception in France as aextramuraluniversity activity was significantly modified in the United Kingdom where it was recognized that most people of retirement age have something to contribute and the emphasis has been on sharing, without formal educational links. Many English-speaking countries have followed this geragogic model, whereas continental European countries have mostly followed the French model. For historical reasons, lifelong learning institute is the term used in the United States for organizations that are similar to U3A groups. A British U3A website reports this about "The Third Age" membership eligibility: "The 'third age' is defined by a time in your life (not necessarily chronological) where you have the o ...

Chitosan
Chitosan is a linear polysaccharide composed of randomly distributed β-(1→4)-linked Glucosamine, D-glucosamine (deacetylated unit) and N-Acetylglucosamine, ''N''-acetyl-D-glucosamine (acetylated unit). It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide. Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking, it can be used as a fining agent, also helping to prevent spoilage. In industry, it can be used in a self-healing polyurethane paint coating. In medicine, it is useful in bandages to reduce bleeding and as an antibacterial agent; it can also be used to help deliver drugs through the skin. Manufacture and properties Chitosan is produced commercially by acetylation, deacetylation of chitin, which is the structural wikt:element, element in the exoskeleton of c ...

Molecular Switch
A molecular switch is a molecule that can be reversibly shifted between two or more stable states. The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric current, microenvironment, or in the presence of ions and other ligands. In some cases, a combination of stimuli is required. The oldest forms of synthetic molecular switches are pH indicators, which display distinct colors as a function of pH. Currently synthetic molecular switches are of interest in the field of nanotechnology for application in molecular computers or responsive drug delivery systems. Molecular switches are also important in biology because many biological functions are based on it, for instance allosteric regulation and vision. They are also one of the simplest examples of molecular machines. Biological molecular switches In cellular biology, proteins act as intracellular signaling molecules by activating another protein i ...

Redox
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate (chemistry), substrate change. Oxidation is the loss of Electron, electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogen ...
