TORONTO, April 17, 2012 /PRNewswire/ - Harry Winston Diamond Corporation (TSX:HW, NYSE:HWD) (the "Company") reports that in the first calendar quarter of 2012, Diavik produced 1.60 million carats from 0.5 million tonnes of ore processed.  Diamonds recovered in the 2012 first quarter was higher by approximately 19% compared to the same quarter of the prior year due to improved grades. In the first quarter of 2011, a higher proportion of mud-rich A-418 type B ore was processed...

Researchers at Rice University and Penn State University have discovered that adding a dash of boron to carbon while creating nanotubes turns them into solid, spongy, reusable blocks that have an astounding ability to absorb oil spilled in water. That’s one of a range of potential innovations for the material created in a single step. The team found for the first time that boron puts kinks and elbows into the nanotubes as they grow and promotes the formation of covalent bonds, which give...

Shares Issued and Outstanding: 80,715,558 TSX: MPV NYSE- AMEX: MDM TORONTO AND NEW YORK, April 12, 2012 /PRNewswire/ - Mountain Province Diamonds Inc. ("Mountain Province", the "Company") (TSX: MPV, NYSE-AMEX: MDM) today announced the final results of the Tuzo Deep drill program, which is designed to define a resource below the current Resource (from surface to 350 meters) of the Tuzo kimberlite pipe. The Tuzo Deep drill program targeted the depth extension of the Tuzo kimberlite...

ZHUZHOU, China, April 11, 2012 /PRNewswire-Asia/ -- Starting from April 2012, Zhuzhou Mingri Cemented Carbide Co.,Ltd. (hereinafter referred to as "Mingri Carbide") will begin to adjust product structure and production capacity mainly for the European and overseas market. It is to provide more comprehensive services to those overseas enterprises in need of cemented carbide, and to meet growing customer demand for products. In order to collect the European market information, the...

As part of an ongoing study, scientists are now forecasting potential forest carbon loss. Working with the Harvard Forest, Smithsonian Institution and LTER Network, scientists have been closely monitoring carbon levels in Massachusetts for more than 30 years. Based on trends in these forests, the scientists are predicting a carbon loss of up to 18% over the next 50 years. In fact, based on these findings, it would be less harmful to harvest these forests instead. “The rebounding forests...

Clark School Researchers Discover Nanoscale Phenomenon, Potential Computer Speed Advantages COLLEGE PARK, Md., April 9, 2012 /PRNewswire-USNewswire/ -- Scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool, like a toaster that burns bread without getting hot. Understanding this phenomenon could lead to new ways of building computer processors that can run at higher speeds without...

A dose of carbon nanotubes more than doubles the growth rate of plant cell cultures — workhorses in the production of everything from lifesaving medications to sweeteners to dyes and perfumes — researchers are reporting. Their study, the first to show that carbon nanotubes boost plant cell division and growth, appears in the journal ACS Nano. Mariya V. Khodakovskaya and colleagues explain that their previous research demonstrated that so-called multiwalled carbon nanotubes (MWCNTs) can...

A series of global warming events called hyperthermals that occurred more than 50 million years ago had a similar origin to a much larger hyperthermal of the period, the Pelaeocene-Eocene Thermal Maximum (PETM), new research has found. The findings represent a breakthrough in understanding the major “burp” of carbon, equivalent to burning the entire reservoir of fossil fuels on Earth, that occurred during the PETM. “As geologists, it unnerves us that we don’t know where this huge...

University of Arizona physicists are making discoveries that may advance electronic circuit technology Graphite, more commonly known as pencil lead, could become the next big thing in the quest for smaller and less power-hungry electronics. Resembling chicken wire on a nano scale, graphene – single sheets of graphite – is only one atom thick, making it the world's thinnest material. Two million graphene sheets stacked up would not be as thick as a credit card. The tricky part...

Measurements taken by a team including National Institute of Standards and Technology (NIST) scientists show that a newly created material has the ability to separate closely related components of natural gas from one another, a task that currently demands a good deal of energy to accomplish. The results might improve the efficiency of the distillation process. The material is a new type of metal-organic framework (MOF), a class of materials whose high surface area and tunable properties...
