Radical electron-induced cellulose-semiconductors
Scientific ReportsBio-semiconductors are expected to be similar to organic semiconductors; however, they have not been utilized in application yet. In this study, we show the origin of electron appearance, N- and S-type negative resistances, rectification, and switching ...

Self-supported cuprous oxide/graphdiyne nanosheets array for efficient ammonia synthesis
ChemPhysMaterElectrocatalytic reduction of nitrates plays a crucial role in ammonia (NH3) production. In this study, a novel cuprous oxide/graphdiyne (Cu2O/GDY) electrocatalyst was synthesized by growing Cu2O/GDY on a Cu substrate with a porous architecture capable ...

Nature Structural Biology, 2002 Cells produce proteases as inactive zymogens. Here, we demonstrate that this tactic can extend beyond proteases. By linking the N and C termini of ribonuclease A, we obstruct the active site with the amino acid sequence recognized by plasmepsin II, a highly specific protease from Plasmodium falciparum.

Electronic conduction in water-adsorbed kenaf cellulose
Scientific ReportsKenaf cellulose can absorb a considerable amount of water, up to approximately 17.5 wt% of its dry weight at saturation. As the water content increases, the imaginary part of the impedance increases, and dielectric loss in the parallel circuit decreases.

Creation Of The Universe [PDF]
, 1993 Creation of the Universe traces the development of the Big Bang theory, from the expansion of the universe to quantum cosmology, from the formation of large scale structure to the physics of the Planck era. Fang Li Zhi, a leading Chinese astrophysicist and Li Shu Xian (co-author and wife) trace the advances in cosmology and recount experiences made by ...
