The science of alcohol

...carbonate, and chloride. Now, these appear naturally in tap water. And where you brew in the world will determine what your iron concentration in your water is. So if you live in a very hard water area, your iron concentration will generally be quite high. And when we talk about hard water, generally what we're talking about is carbonate, and that's the lime scale that...

UK nuclear industry faces Brexit fall-out

...carbon emissions. It has withdrawn subsidies from onshore wind and solar power, and underwritten new nuclear stations instead. However, the industry relies on foreign companies − based both in the EU and outside − that provide parts, fuel and raw materials. When the UK leaves Euratom, this trade will be contrary to international law. Tom Greatrex, chief executive of...

Multipoint cutting (rotational)

...carbon steel. Carbide tips are brazed or clamped into position, and are used for harder materials and/or higher production rates. They are more expensive to buy, and require a more rigid, powerful and faster machine, but have a longer life and 3–10 times the cutting speed of high speed steel. Materials Drilling Almost any material can be drilled, the only limitation...

Chemical vapour deposition (CVD)

...carbon and nitrogen (instead of CH4 and N2), and the lower temperatures reduce the risk of edge brittleness in cemented carbide tips. PACVD uses an argon plasma to heat the substrate material, thus lowering the temperature of the process to 400–500˚C. In diffusion CVD the coating, substrate and temperature are chosen so the coating reacts with the substrate to produce...

Flame cutting

...carbon and low alloy steels. Most non-ferrous metals cannot be flame cut, although titanium, which does not fulfil the above requirements, can be successfully flame cut. Despite precautions, carburisation and hardening usually occur in the thin solidified “re-cast” layer. High alloy steels, cast irons and non-ferrous metals cannot usually be cut by conventional flame...

...carbonated beverages), prebiotics, and/or being afflicted with gastrointestinal diseases such as IBS, GERD, or a Giardia infection. While many drugs enhance one's farting ability, there are also drugs capable of cracking down on crop dusting. Let's look at both groups. What drugs cause people to have gas? Drugs known to cause flatulence include laxatives, antacids,...

...carbon sector can reduce the risk of exposure to stranded assets while simultaneously helping achieve net-zero. COP26 has been touted as the last best chance to avert climate catastrophe. One of its four goals is to mobilise finance to help achieve climate aims with a target of raising $100bn per year towards financing the pathway to net zero. COP-associated global and...
