Scientists at Rice University and collaborators in Taiwan and China have successfully grown atom-thick sheets of hexagonal boron nitride as two-inch diameter crystals across a wafer. Surprisingly, they achieved this long-sought goal of making perfectly ordered crystals of hexagonal boron nitride by taking advantage of disorder among the meandering steps on a copper substrate.

Ever since graphene's discovery in 2004, scientists have looked for ways to put this 2D material to work. Last year, scientists at Lawrence Berkeley National Laboratory developed a multitasking graphene device that switches from a superconductor, which efficiently conducts electricity, to an insulator, which resists the flow of electric current, and back again to a superconductor. Now, the scientists have tapped into the graphene system's talent for juggling not just two properties, but three: superconducting, insulating, and a type of magnetism called ferromagnetism.

Researchers from the University of South Australia, McMaster University in Canada, and Texas A&M University have shown that curcumin can be delivered effectively into human cells via nanoparticles. The researchers have shown in animal experiments that nanoparticles containing curcumin not only prevents cognitive deterioration but also reverses the damage. This finding paves the way for clinical development trials for Alzheimer’s disease.

Scientists at Rice University, Biola University, and the Texas A&M Health Science Center have demonstrated that molecular nanomachines that spin up to 3 million times per second can target diseased cells and kill them in minutes. The nanomachines could be used to control parasites and treat skin cancer.

An international team of scientists and engineers has discovered one-dimensional defects in a two-dimensional structure of porous material – a zeolite called MFI. By imaging the atomic structure of the MFI nanosheets at unprecedented detail, the researchers found that these one-dimensional defects resulted in a unique reinforced nanosheet structure that changed the filtration properties of the nanosheet. The discovery could improve efficiency in the production of gasoline, plastics, and biofuels.
