It originated in the Netherlands but has since gone global. It has much in common with The Restart Project but is a separate organisation with slightly different emphasis and aims.") | |||

It was started in London, offering "restart parties" at which skilled amateur fixers could help members of the public repair their broken electrical and electronic gadgets. It has since gone global and assumed a leading role in campaigning for Right to Repair and related issues. Whilst it shares many aims with Glossary:Repair...") | ||||

For example, recycled plastic may contain contamination from its previous use and hence cannot be used for food packaging, and steel from scap cars can be used to make steel girders but not high quality engineering steels. Most recycling is in fact downcycling.") | |||

It then remains conducting until the current falls below a small holding current. It is similar in operation to a DIAC except for the higher threshold voltage. It has a few niche applications...") | |||

These include lead, mercury, cadmium and hexavalent chromium, together with a further six organic chemicals. It took effect in the EU in 2006.") | ||||
| N 17:15 | Glossary:WEEE diffhist +352 Philip talk contribs (Created page with "The Waste Electrical and Electronic Equipment or WEEE Directive obligates producers and distributors of electrical equipment placed on the market after 2005 to make provision for its end of life collection and recycling. It is applicable in the UK and the EU. It has been criticised for its disregard for reuse or repair as a means of reducing e-waste.") | ||||
| N 17:02 | Glossary:Soak test diffhist +308 Philip talk contribs (Created page with "A soak test is an extended test of a device following manufacture or repair, with the aim of shaking out any manufacturing defects or shortcomings in the repair. Sometimes this will be performed at full power or in some other way designed to stress any weak components and precipitate any incipient failures.") | ||||
| N 16:55 | Glossary:Bathtub curve diffhist +441 Philip talk contribs (Created page with "Reliability studies in many fields tend to show a common pattern for failures. Manufacturing defects are the principal cause of early life failures, but once these have all been shaken out the failure rate remains fairly low through the expected lifetime of a device. The failure rate then starts to climb as components begin to wear out. So plotting the failure rate against time gives a U-shaped curve, commonly known as the bathtub curve.") | ||||

| N 15:26 | Glossary:Critical Raw Materials diffhist +247 Philip talk contribs (Created page with "CRM or Critical Raw Materials are those raw materials in critically short supply. This may be because there simply isn't much of them waiting to be mined, or because what there is is largely controlled by unfriendly or potentially hostile nations.") | ||||
| N 15:20 | Glossary:Upcycle diffhist +168 Philip talk contribs (Created page with "Upcycling is the practice of taking disused or faulty items or their major components and reusing them in a different way, hence saving them from recycling or landfill.") | ||||
| N 15:15 | Glossary:Refurbishment diffhist +298 Philip talk contribs (Created page with "Reurbishment is the practice of taking used items and giving them a new lease of life by replacing worn or damaged parts, bringing them up to date with a fresh software installation and perhaps replacing a slow hard drive with a much faster SSD.") | ||||
| N 15:04 | Glossary:Remanufacture diffhist +241 Philip talk contribs (Created page with "Remanufacture is the practice of creating good-as-new products using some proportion of pre-used parts. Common examples are ink and toner cartridges and laptop batteries, could equally include a laptop given a new case, keyboard and battery.") | ||||
| N 14:59 | Glossary:Recycle diffhist +379 Philip talk contribs (Created page with "Recycling is the practice of recovering raw materials from waste items. This is generally inefficient and often impracticable or uneconomic for valuable materials used in small quantities. Furtthermore the resultant raw materials may not be of sufficient quality for demanding applications. Hence it is regarded as the second-worst option, ahead only of landfill or incineration.") | ||||
| N 14:50 | Glossary:Circular economy diffhist +248 Philip talk contribs (Created page with "A circular economy is one where a minimum of items or their parts are sent for landfill or incineration, and a high proportion are either reused, repaired or recycled, so minimising the consumption of raw materials and the pre-use carbon footprint.") | ||||
| N 14:45 | Glossary:Repair diffhist +201 Philip talk contribs (Created page with "Repair is the second option (after reuse) in a circular economy. It has been shown that many devices sent for recycling could actually be repaired relatively easily and hence given a new lease of life.") | ||||
| N 14:42 | Glossary:Reuse diffhist +225 Philip talk contribs (Created page with "Reuse is the preferred option in a circular economy. Many items are discarded because they have been replaced by a newer model, or simply fallen into disuse, but could be given a second life if sold or donated to a new owner.") | ||||
| N 14:36 | Glossary:E-Waste diffhist +166 Philip talk contribs (Created page with "e-Waste is all those electrical and electronic goods discarded by their owner, whether because they are faulty, no longer needed, or simply replaced by a newer model.") | ||||

In electronics, many compounds of gallium are semiconductors with useful properties. Gallium arsenide devices are able to operate at much higher frequencies than their silicon counterparts and so are widely used in mobile phones and satellite comunications. Various other gallium compounds are used in practically all visible and infra-red LEDs.") | ||||
| N 19:48 | Glossary:Silicon Carbide diffhist +440 Philip talk contribs (Created page with "Silicon carbide (as carborundum) has long been used as an abrasive, but it is also a semiconductor with useful properties for high power applications. In recent years silicon carbide devices such as MOSFETs having higher voltage and power ratings than equivalent silicon devices have been increasingly used in applications such as EVs and power conversion.") | ||||
