Morphologies of porous molybdenum disulfide prepared by researchers show good performance in hydrogenation of phenol

11.10. 2017 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Molybdenum disulfide (MoS2) is a transition metal chalcogenide material widely used in photocatalysis, synthesis catalyst, hydrodesulfurization, hydrodeoxygenation, electronic, optical, mechanical, even in hydrogen evolution reaction (HER). The morphology-controlled preparation of MoS2 is currently highly topical. Many preparation routes have been developed for synthesis of nanometer MoS2 over the last decades, and MoS2 nano-materials with different morphologies, particle sizes, and porous features can be obtained from different raw materials through different pathways. However, the morphology and crystal size of MoS2 was uncontrolled and the properties of the obtained material were variable.

New study is a step toward creating planes that travel at hypersonic speed

10.10. 2017 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

An average flight from Miami to Seattle takes about six hours and 40 minutes, but imagine being able to reduce that time to 50 minutes or less. A recent study by researchers at NASA and Binghamton University, State University of New York, could lead to a drastic decrease in flight times. The study, funded in part by the U.S. Air Force, is one of the first steps toward the creation of planes able to move at hypersonic speeds, five to 10 times the speed of sound.

Chemically stabilizing atomically flat materials improves their potential for commercial application

05.10. 2017 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Two-dimensional materials could underpin a novel family of flexible, low-power electronic devices, but their success depends on ensuring the layers are chemically stable. A*STAR researchers now show that one 2-D material, phosphorene, can be stabilized with the right choice of substrate and an electric field.
