Phase-pure ε-iron carbide catalysts amenable to scale-up exhibit low CO 2 selectivity and high stability in the FT reaction.
Oil has long been the dominant feedstock for producing fuels and chemicals, but coal, natural gas biomass are increasingly explored alternatives
Serving as shape control agent, polyvinyl pyrrolidone (PVP) has been widely used in chemical synthesis of metal nanoparticles. However, the role molecular weight (MW) PVP rarely concerned. In this study, we show a facile method to shapes silver nanocrystals using with different MWs. PVPMW=8,000, PVPMW=29,000, PVPMW=40,000, and PVPMW=1,300,000 are compared present study. Surprisingly, high-yield rodlike nanostructures, nanospheres, nanowires can be obtained under same growth environment...
A non-noble intermetallic compound catalyst consisting of Ni3Ga nanoparticles supported on Al2O3 that exhibits high selectivity (∼94%), comparable activity (TOF = 4.7 × 10–2 s–1), good stability (∼94% to 81% over the 82 h test), and regenerability in direct dehydrogenation propane propylene at 600 °C has been developed.

Anisotropy is a manifestation of lowered symmetry in material systems that have profound fundamental and technological implications. For van der Waals magnets, the two-dimensional (2D) nature greatly enhances effect in-plane anisotropy. However, electrical manipulation such anisotropy as well demonstration possible applications remains elusive. In particular, in-situ modulation spin transport, vital for spintronics applications, has yet to be achieved. Here, we realized giant electrically...

One of the well-known observations in Fischer-Tropsch (FT) reaction is that CH4 selectivity for cobalt catalysts always higher than value expected on basis Anderson-Schulz-Flory (ASF) distribution. Depositing graphitic carbon a catalyst strongly suppresses this non-ASF CH4, while formation hydrocarbons much less affected. Carbon was laid down via Boudouard reaction. We provide evidence amorphous does not influence FT reaction, as it can be easily hydrogenated under conditions. Graphitic...
In recent years, bismuth-based semiconductors have become a research hotspot in the new semiconductor field due to their unique optical and electronic properties.
Abstract Transition metal compounds with kagome structure have been found to exhibit a variety of exotic structural, electronic, and magnetic orders. These orders are competing energies very close each other, resulting in complex phase transitions. Some the phases easily observable, such as charge density wave (CDW) superconducting phase, while others more challenging identify characterize. Here we present magneto-transport evidence new below ~ 35 K topological CsV 3 Sb 5 (CVS) thin flakes...

In this paper, a thermally reversible self-healing polysiloxane elastomer based on Diels–Alder (DA) chemistry was successfully prepared via containing maleimide groups and furan rings. The hyperbranched (HPSis) rings double bonds synthesized introduced to improve the mechanical strength of polymer. without HPSis only 0.20 MPa; however, it can be increased 0.87 MPa with introduction HPSis. Since contain multi-furan required for reactions, addition would not have negative effect performance....
Synthesis of kinetically trapped, alumina-supported Ni3Ga nanoparticles with particle surface composition partially controlled by off-stoichiometric Ni:Ga loading ratios enabled active, highly selective, and stable catalysts to be developed for the direct dehydrogenation ethane ethylene. Experimental studies indicated a correlation between superstoichiometric Ga ethylene selectivity yet an inverse conversion. A catalyst 1:1 ratio exhibited good balance activity (TOF 5.0 × 10–2 s–1), (94%),...
Poly(p-phenylene benzobisoxazole) (PBO) fibers are some of the strongest organic polymer fibers, however, even stronger can be made using carbon nanotubes (CNTs). In present study, copolymerization functionalized CNTs with PBO was successfully carried out by one-pot in situ polycondensation polyphosphoric acid. Pristine were first oxidized to CNT–COOH and then modified 4,6-diaminoresorcinol (DAR) or trimer (DAR–TA–DAR) improve reactivity, solubility, dispersivity, interfacial adhesion...
Two-dimensional (2D) materials have become more advantageous compared with traditional semiconductor for fabrication of modern photodetectors operating at room temperature and possessing small volume low power consumption. However, the weak absorption caused by atomic thickness severely limits performance employing 2D as active channels. Plasmonic nanomaterials can manipulate light subwavelength scale been viewed a powerful tool to achieve enhanced photoresponse in devices. In this review,...
Abstract A new methodology based on core alloying and shell gradient-doping are developed for the synthesis of nanohybrids, realized by coupled competitive reactions, or sequenced reducing-nucleation co-precipitation reaction mixed metal salts in a microfluidic batch-cooling process. The latent time nucleation growth nanohybrids can be well controlled due to formation controllable intermediates reactions. Thus, spatiotemporal-resolved hybrid process, which enables us investigate nanohybrid...
