environmentPotential global warming solution with rapid magnesite creation

Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale then it can help offset global warming. A tonne of naturally-occurring magnesite can remove around half …

diamondSix inch wide diamond disks guide megawatt of microwave heating for nuclear fusion

Researchers of Karlsruhe Institute of Technology (KIT) and the company Diamond Materials have developed 6 inch wide diamond disks for window units to heat the plasma in fusion reactors. Gyrotrons are microwave oscillators generating a temperature of up to 150 …

materialsHarmful plastic straw bans versus actual ocean cleanup technology

Banning plastic straws and plastic bags are justified to as part of a solution to plastic in the oceans and reduction of landfill. Even advocates admit that these regulations will not solve the ocean problem. Straw bans are intended as …

energyGraphene foam for wearables and with scalable 3D production

A Glasgow University team has developed medical sensors powered by a porous foam of graphene and silver, an advance with potential applications in the wearable device market. They used a commercially available graphene foam to make a layered structure with …

3dLockheed 3D printing titanium space parts using garage sized printer

Lockheed is 3D printing titanum fuel tank for Lockheed Martin’s largest satellites. Using this manufacturing method, tank delivery time went down from two years to three months (nine times faster) and they are no longer wasting 80% of the materials. …

energyA voltage breakthrough with perovskite solar cells to edge closer to commercialization

A new technique has produced the highest performing inverted perovskite solar cell ever recorded. A team of researchers from Peking University and the Universities of Surrey, Oxford and Cambridge detail a new way to reduce an unwanted process called non-radiative …

colonizationGateway Foundation Spaceport envisions large scale space construction

Orbital Assembly and the Gateway Foundation are working on a reasonable set of plans and steps to build a space station that is 488 meters in diameter. They would start with a hub that is 78 meters wide. The National …

3d printingBreakthrough for large scale printing of wood at ten times lower cost than other 3D printing

Cellulose is the most abundant and broadly distributed organic compound and industrial by-product on Earth. The bottom-up use of cellulose to fabricate 3D objects has had big problems that prevented printing wood for practical applications. Use in combination with plastics …

energyPerovskite and silicon tandem solar could beat silicon solar in some to many situations

Researchers from EPFL’s Photovoltaics Laboratory and the CSEM PV-center have developed an economically competitive solution to silicon solar cells. They have integrated a perovskite cell directly on top of a standard silicon-based cell, obtaining a record efficiency of 25.2 percent. …

materialsNew Class of 2D Artificial Materials Created

Researchers created a new class of two-dimensional artificial materials with ferroelectric-like properties at room temperature that don’t exist in nature yet can conduct electricity. Above – This image shows the positions of atoms in a ferroelectric-like metal that contains barium …
