Scientists at Drexel University in Pennsylvania have developed a technology that can heat water faster up to three times. This can be really helpful in conserving energy in industrial power plants or large-scale electronic cooling systems. It can also be used to make tea quickly, technically speaking.

The air bubbles created while heating water temporarily insulate heating elements from the surrounding water, slowing down the transfer of heat. The scientists have found that the size of these bubbles can be reduced by coating a heating element with a virus found on tobacco plants.

The reduction in bubble size will also prevent ‘critical heat flux’ caused when bubbles merge into a blanket surrounding the element hampering the transfer heat to the water.

‘What happens then is the dry surface gets hotter and hotter, like a pan on the stove without water in it. This failure can lead to the simple destruction of electronic components, or in power plant cooling applications, the catastrophic meltdown of a nuclear reactor.’  Matthew McCarthy, an engineer at Drexel University was quoted in the PSFK magazine.

Scientists had been looking for ways to develop a surface that repels bubbles and keep the boiling surface wet. McCarthy’s team found that tobacco mosaic virus was perfect for the purpose.

They have genetically modified the virus so that it can attach itself to any surface. Once the virus is attached to the surface, it is coated with a microscopically thin layer of nickel to make the virus inert.  This forms a sort of metallic grass which can wick moisture to the surface and repel bubbles.

Scientific research testifies to the health benefits of all kinds of tea, which not only help with beauty factors but also weight loss and hydration of skin, reports femalefirst.co.uk.

Experts at the Tea Advisory Panel (TAP), which provides objective information about tea, have enlisted the beauty secrets behind a cup of tea:

* Provides water to skin: Good hydration is important for the health of all our body organs, tissues and cells. A recent study suggested that drinking up to six cups of tea per day, has the same hydrating properties to water.

* The role of tea in skin health: Healthy skin is well hydrated skin.Drinking enough fluid which can include all types of tea is important for restoring fluid loss which can occur to a greater extent during summer. Adequate hydration can help to keep the skin in good condition.

White tea has also been shown to have anti-inflammatory activity in human skin. In one study, human skin cells were exposed in the laboratory to hydrogen peroxide. White tea was shown to reduce the inflammation that would normally result from hydrogen peroxide exposure.

* Tea and weight loss: Tea consumption has been associated with less weight gain over time. Drinking tea more than once a week has been linked to lower body fat percentages and smaller waist circumferences than non-tea drinkers. It is also important to note that all teas, including black tea, with semi-skimmed milk and no sugar, is a lower calorie alternative than other popular drinks. Tea has been recommended to take precedence over other beverages to help reduce energy intake and maintain hydration.
