Glucose chain shortening and lengthening. Glucose chain shortening and lengthening is the chemical processes for decreasing or increasing the carbon chain length of glucose. Glucose can be shortened by oxidation and decarboxylation to generate arabinose, a reaction known as the Ruff degradation. To increase the glucose carbon chain, a series of chemical reactions can be used to add one more carbon at the aldehyde end of glucose; this process is known as the Kiliani–Fischer synthesis.

Glucose chain shortening
Glucose can react with bromine in water to form the aldonic acid, which can then undergo oxidative decarboxylation with hydrogen peroxide and iron (III) acetate to form arabinose. This reaction can be conducted iteratively, shortening one carbon at a time to generate sugars with smaller chain lengths.

Glucose chain lengthening
Glucose can be the substrate in Kiliani–Fischer synthesis that adds a carbon to the aldehyde group and forms sugars with one more carbon than the substrate. The first step is nucleophilic addition of aqueous cyanide to aldehyde group in glucose to generate the cyanohydrin. Then cyanohydrin is hydrolyzed to form aldonic acid lactone upon heating. Finally, the aldonic acid lactone is reduced with sodium amalgam non-stereoselectively to produce heptose; two isomers with both stereoisomers at C2 are generated.

Polyfuran. Polyfuran (PFu) is a polymer that consists of multiple furanylene rings.  Such materials are of interest for their potential in molecular electronics, although much less studied than polythiophenes and polypyrroles. Polyfuran is distinct from furan resins, a class of non-conjugated polymers.  Furan resins are of commercial interest, in contrast to polyfuran.

Polyfurans can be prepared by electrochemical approaches.  The mechanism of polymerization is proposed to involve radical cation intermediates, i.e. species with the formula C4R4O+.

Polyfurans can also be produced using acid catalysts. Radical polymerization has also been explored, and oxidative cationic polymerization.

CC-HOD. CC-HOD (Catalytic Carbon - Hydrogen On Demand) is a process which splits water into hydrogen and oxygen at low temperatures.

History 
The CC-HOD method was discovered by Howard Phillips, managing director of Phillips Company, a pharmaceutical manufacturing company.

Hydrogen is energy dense and environmentally benign because upon combustion it produces only water vapor. Most hydrogen fuel is produced by electrolysis, a process that requires substantial energy. Phillips proposed that CC-HOD could become an alternative to electrolysis.

Process 

CC-HOD requires catalytic carbon, scrap metal, and water heated only modestly above ambient temperature. Aluminium is submerged in a tank with the catalytic carbon. Pure hydrogen gas is formed when the water reaches a temperature of about . Oxygen remains in the tank, where it bonds with the aluminium to form aluminium hydroxide:

Al + H²O + CC = CC + Al(OH)³ + H²

Research 

CC-HOD has mainly been researched by open science projects. LENR Ltd. is a UK based open research group specializing in validating novel energy technologies. They tested CC-HOD for several years and claimed it was reliable.

Potential applications 

Besides production of clean energy for transportation and heating, CC-HOD can be used for recycling scrap metal. Depending on which type of metal is used, the byproducts from the process could be used to manufacture electronics, deodorant, paint, or ink.

Patent 

A US patent application titled 'Methods and systems for producing hydrogen' was filed June 24, 2012.

Nitronic. Nitronic is the trade name for a collection of nitrogen-strengthened stainless steel alloys. They are austenitic stainless steels.

History
Nitronic alloys were developed by Armco Steel. The first of these alloys, Nitronic 40, was introduced in 1961. Since 2022, the trademark has been owned by Cleveland-Cliffs Steel Corp., successor to AK Steel.  Electralloy is the licensed producer in North America for a wide range of Nitronic products.

The Nitronic name is due to the addition of nitrogen to the alloy, which enhances the strength internally rather than being nitrided on the surface, as some steel are treated. The nitrogen is homogeneous throughout the material. Nitronic materials have about twice the yield strength of 304L and 316L.

Uses
Nitronic 30 is used to lighten transportation vehicles. Buses and railcars benefit from the high strength-to-weight ratio for weight savings. Nitronic 40 is used at cryogenic temperatures. and in the aerospace industry as hydraulic tubing.
Nitronic 50 is used in marine environments, including boat shafting and solid rod rigging. Nitronic 60 and a similar alloy Gall-Tough have high resistance to galling, a form of wear caused by adhesion between sliding surfaces, and metal-to-metal wear.

Composition
Nitronic alloys have widely varying compositions, but all are predominantly iron, chromium, manganese and nitrogen.

Ian Beer (hacker). Ian Beer is a British computer security expert and white hat hacker, currently residing in Switzerland and working for Google as part of its 
Project Zero. He has been lauded by some as one of the best iOS hackers. Beer was the first security expert to publish his findings under the "Project Zero" name in the spring of 2014; at this time, the project was not yet revealed and crediting the newly discovered vulnerabilities to it led to some speculation.

He is known for discovering a large number of security vulnerabilities in Apple products, including iOS, Safari and macOS, as well as helping create jailbreaks for iOS versions. One such discovery forced Apple to rewrite significant parts of the macOS and iOS kernel. Beer is also a vocal critic of Apple concerning its bug bounty program for iOS announced in 2016. The invite only program has been accused of low payouts. Beer has also criticized the company for not disclosing to its users why updates that fix the bugs should be installed.

Amoriguard. Amoriguard is a water-based paint with fillers based on recycled industrial waste. The colour has an effective 70% mass of solids, which occupy a volume of at least 55% excluding water. It was invented in South Africa by Mulalo Doyoyo and co-developed by Ryan Purchase.

Substances in the paint such as volatile organic compounds, ammonia, formaldehyde, lead, alkyl phenol ethoxylate and glycol are low in quantity or absent. It is manufactured below critical pigment volume concentration (CPVC) which means that most voids between pigment particles in the dried film are filled with solid particles as opposed to air. The paint is hydrophobic and chemical-resistant.
