Fluorine Speeds Up Two-Dimensional Materials GrowthBy spatially confining fluorine, scientists could activate feeding gases while disabling its harmful effectsBack in 2004, the physics community was just beginning to recognize the existence of truly two-dimensional (2D) material, graphene. Fast forward to 2019, scientists explore a breadth of different 2D materials, expecting t... Name : 전체관리자 Hits : 150 2019.07.16

Paris Agreement does not rule out ice-free ArcticResearch published in this week’s issue of Nature Communications reveals a considerable chance for an ice-free Arctic Ocean at global warming limits stipulated in the Paris Agreement. Scientists from South Korea, Australia and the USA used results from climate models and a new statistical approach to calculate the likelihood for ... Name : 전체관리자 Hits : 175 2019.07.10

Graphenes now go monolayer and single crystalline- The high-performance device is fabricated in “clean areas” in between graphene folds -Director Rodney Ruoff’s research group from the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS) at the Ulsan National Institute of Science and Technology (UNIST) has reported a truly single laye...

Randomly stacked graphene layers approach the theoretical performance of graphiteMixed stacking order of 100 graphene layers gets the most out of graphite▲ Graphite | by James St. John from www.flickr.comAlthough both diamond and graphite are composed of only carbon atoms, the arrangement of atoms differ causing discrete properties. In graphite, the carbon atoms are arranged in... Name : 전체관리자 Hits : 413 2019.06.19

How to enlarge 2D materials as single crystals?Turn it around and find the right symmetric codeWhat makes something a crystal? A transparent and glittery gemstone? Not necessarily in the microscopic world. When all of its atoms are arranged in accordance with specific mathematical rules, we call the material a single crystal. Like the natural world has its unique symmetry just ... Name : 전체관리자 Hits : 392 2019.05.23

Droplet trains reveal how nature navigates blood trafficScientists found alternating flocks in micro-channels and explained how the flocks can be thinned.Nearing a decision point, online traffic maps recommend a less-crowded route over the other ways with several slow spots. For most of us, the choice seems clear. Still, have you ever wondered whether this collectively preferri... Name : 전체관리자 Hits : 615 2019.04.23

Heterogeneous Catalyst Goes EnzymaticCooperative interplay between single copper atoms and adjacent titania environment enables low-cost, efficient, and eco-friendly photocatalyst for hydrogen production▲ Figure 1: 3D image of TiO2 ball covered single copper atoms.It was crucial for this study to design site-specific single atom catalysts, since this single-atom structure direc...

Natural Climate Processes Overshadow Recent Human-induced Walker Circulation TrendsA new study, published this week in the journal Nature Climate Change, shows that the recent intensification of the equatorial Pacific wind system, known as Walker Circulation, is unrelated to human influences and can be explained by natural processes. This result ends a long-standing debate on t... Name : 전체관리자 Hits : 755 2019.04.02
