Horizontal magnetic tunneling in a field-effect device integrated on Silicon

The choice for energy-efficient technologies is not a matter of price choice but it is slowly turning into a matter of heat. A work recently published in Nature’s Scientific Reports suggests devices fabricated directly on Silicon with magnetic tunnel junctions governed by electric pulses, which means without current and minimizing the problem of overheating.

New Nanomaterials Taking Research to Mexico, Possibly into Space

Professors Linda Hirst and Sayantani Ghosh are combining liquid crystals with nanoparticles such as gold and quantum dots to come up with a new platform that could have applications in fields such as optics and medicine.

A National Science Foundation grant of $410,000 will help Hirst and Ghosh study the fundamental physics behind the capsules that form when the two materials are combined.

Berkeley Lab to Investigate Link between Thirdhand Smoke and Cancer

Berkeley Lab scientists have been awarded $1.3 million to study health impacts of thirdhand smoke.

Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have been awarded $1.3 million for two sets of studies to better understand the health impacts of thirdhand smoke, the noxious residue that clings to virtually all indoor surfaces long after the secondhand smoke from a cigarette has cleared out.

A Different Type of 2D Semiconductor

Berkeley Lab Researchers Produce First Ultrathin Sheets of Perovskite Hybrids

To the growing list of two-dimensional semiconductors, such as graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites. However, unlike the other contenders, which are covalent semiconductors, these 2D hybrid perovskites are ionic materials, which gives them special properties of their own.

Iranian Scientists Use Polymeric Nanocomposites as Substitute for Steel Tanks

Iranian researchers from Nuclear Science and Technology Research Institute (NSTRI) in association with researchers from University of Tehran succeeded in the production of polymeric nanocomposite with high thermal, chemical and mechanical resistance.

Nowadays, the creation of nuclear wastes and radioactive contaminants is inevitable due to the significant progresses in nuclear industry and its application in various industries and medical and agricultural issues. It is necessary to store or expulse radioactive wastes according to specific regulations due to the unique properties of radioactive materials.

A different type of 2-D semiconductor: Berkeley Lab researchers produce first ultrathin sheets of perovskite hybrids

To the growing list of two-dimensional semiconductors, such as graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites. However, unlike the other contenders, which are covalent semiconductors, these 2D hybrid perovskites are ionic materials, which gives them special properties of their own.

Researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have successfully grown atomically thin 2D sheets of organic-inorganic hybrid perovskites from solution. The ultrathin sheets are of high quality, large in area, and square-shaped. They also exhibited efficient photoluminescence, color-tunability, and a unique structural relaxation not found in covalent semiconductor sheets.

Celebrating Hubble and the Spirit of Exploration

Before April 24, 1990, seeing photos of space from space was not an option. Since then however, as spectators we’ve seen some photos that are nearly unimaginable. Why is that date so special? It was the date the Hubble Space Telescope was launched into space, making it a bit more than 25 years old.
