Vermiculture is the culture of earthworms. The goal is to continually increase the number of worms in order to obtain a sustainable harvest. The worms are either used to expand a vermicomposting operation or sold to customers who use them for the same or other purposes. Vermicomposting is the process by which worms are used to convert organic materials (usually wastes) into a humus-like materia...

Compost is the product resulting from the controlled biological decomposition of organic material that has been sanitized through the generation of heat and stabilized to the point that it is beneficial to plant growth. Compost bears little physical resemblance to the raw material from which it originated. Compost is an organic matter resource that has the unique ability to improve the chemical...

We describe the discovery and evaluation of a semi-perfluoroalkyl resorcinarene photoresist which is processable in hydrofluoroether solvents (HFEs). This novel, high-performance imaging material is specifically designed to be orthogonal to the vast majority of organic conductors and semiconductors, and hence enable their photolithographic patterning. Furthermore, this material paves the way fo...

An overview of the synthesis, physical properties, and use as material for organic light-emitting diodes (OLEDs) of linear organic π-conjugated systems incorporating phosphole and thiophene rings is presented.

Poly(anthraquinonyl sulfide) is synthesized and investigated as a novel organic cathode material for rechargeable lithium batteries, which shows excellent reversibility and cyclabilty, and gives important insights into developing a new generation of organic cathode materials with higher performance.

A new high triplet organic semi-conductor based on a donor-spiro-acceptor design has been synthesised and used as a host material in high performance (EQE = 11.4%) sky blue phosphorescent organic light emitting diodes.

Since the 1950s a lot of effort has been devoted into the development of organic conductors. By a substantial degree this has been inspired by W. A. Little’s theoretical analysis of London’s idea that superconductivity might occur in organic macromolecules or polymers [1]. Over time this has resulted in the discovery of several organic metals and superconductors, albeit not with spectacularly h...

A use-dilution procedure and screening method are proposed to aid the hospital bacteriologist in selecting the most effective disinfectants. Sixteen disinfectants were tested with and without organic material on six different organisms. Sporadic results usually obtained with quaternaries tested by the procedure of the Association of Official Agricultural Chemists (AOAC) were eliminated by the m...

Composting is a biological decomposition process where microorganisms convert raw organic materials into relatively stable humus-like material. During decomposition, microorganisms assimilate complex organic substances and release inorganic nutrients. An adequate composting process kills pathogens and stabilizes compost organic carbon before the material is land-applied. In 1997, 27.2 million m...
