#Gold-diamond nanodevice for hyperlocalised cancer therapy: Gold nanorods can be used as remote controlled nanoheaters delivering the right amount of thermal treatment to cancer cells,
thanks to diamond nanocrystals used as temperature sensors Abstract: Precise targeting biological molecules, such as cancer cells,
Using a chemical method to attach gold nanorods to the surface of a diamond nanocrystal, the authors have invented a new biocompatible nanodevice.
The authors'lab specialises in fabricating bright fluorescent diamond nanocrystals. The paticularity of these nanocrystals is that they contain a high concentration of punctual colour centre defects.
The novelty of this study is that it shows that it is possible to use diamond nanocrystals as hypersensitive temperature sensors with a high spatial resolution-ranging from 10 to 100 nanometers-to monitor the amount of heat delivered to cancer cells s

phototrophic iron-oxidizing bacteria removed electrons from the magnetite, thereby discharging it. During the nighttime conditions, the iron-reducing bacteria took over

it is thought that in the environment the potential for magnetite to act as a battery could extend to many other types of bacteria
There has been considerable recent work on using magnetite to clean up toxic metals. For example, magnetite can reduce the toxic form of chromium, chromium VI, to the less toxic chromium (III),
which can then be incorporated into a magnetite crystal. The fact that this magnetite may then be exposed to these reducing bacteria could potentially enhance its remediation capacity.

the country will no longer be burning coal to generate electricity, and will stop pumping around 1,
600 kilotonnes of CO2 into the atmosphere within three years. ts closure marks the end of coal fired power generation in New zealand,"
*but the move is still a significant step towards a world where burning coal is no longer the cheapest and most reliable way to generate electricity."
"Historically, coal has played an important role in ensuring the security of New zealand electricity supply, particularly in dry years where our hydro-lake levels are said low
Although it would be nice to see governments force coal fired power stations out of business, it actually feels more exciting that coal fired systems no longer make financial sense.
In fact, Genesis Energy Chief executive Albert Brantley estimated in a press release that the company will save around NZ$20 to 25 million (US$13 to 16.5 million) each year by not running the coal fired generators.
The two remaining coal-burning generators are located at Genesis Energy's Huntly Power station in Waikato on the country's North Island.
The power station itself will continue to run on natural gas for the foreseeable future. Over the past year and a half, New zealand has increased significantly the amount of electricity it produces from renewable energy,
and the shift from coal will help us to achieve our ambitious goal of having 90 percent of New zealand electricity supply generated by renewables by 2025."
