A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide. The study also found that after the material is produced, its structural and chemical properties continue to evolve for more than a month as a result of continuing chemical reactions with hydrogen.

In experiments at SLAC National Accelerator Laboratory, a powerful X-ray laser blasted solid carbon crystals into a liquid and plasma even faster than expected, raising new questions about how these intense beams interact with matter. The tests took place at the Linac Coherent Light Source, or LCLS, using a pioneering technique to simultaneously blast and probe samples of graphite, a pure form of carbon.

University
at Buffalo researchers are making significant progress on rust-proofing
steel using a graphene-based composite that could serve as a nontoxic
alternative to coatings that contain hexavalent chromium, a probable
carcinogen.

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds. Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford University, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma.

Gallium
nitride, a semiconductor material found in bright lights since the
1990s, is used in wireless applications because of its high efficiency
and high voltage operation. However, it’s difficult to remove heat from
GaN electronics, which limits applications and markets. Researchers at
the University of California, Riverside, have made a material from
graphene that does the job, and it looks a lot like a patterned quilt.

Researchers
in Switzerland have created a new nanocomposite that combines the best
features of graphene and protein fibrils, the two main ingredients of a
specialized type of paper. The material is created in much the same way
as normal cellulose paper, but the properties are far different. Shape
memory, electrical conductivity, and hydrophobia all offer interesting
application possibilities.

Researchers at the University of Notre Dame have shown that it is possible to efficiently manipulate terahertz electromagnetic waves with atomically thin graphene layers. This achievement sets the stage for development of compact, efficient, and cost-effective devices and systems operating in the terahertz band.
