Increasing global challenges such as climate change, environmental pollution, and energy shortage have stimulated the worldwide explorations into novel clean materials for their applications in capture of carbon dioxide, a major greenhouse gas, toxic pollutants, conversion, storage. In this study, two microstructured carbons, namely N‐doped pillaring layered (NC) N, S codoped honeycomb (NSC), been fabricated through one‐pot pyrolysis process mixture containing glucose, sodium bicarbonate,...
We have synthesized ternary InGaAs nanowires on (111)B GaAs surfaces by metal−organic chemical vapor deposition. Au colloidal nanoparticles were employed to catalyze nanowire growth. observed the strong influence of density height, tapering, and base shape specific with high In composition. This dependency was attributed large difference diffusion length between Ga reaction species, being more mobile species. Energy dispersive X-ray spectroscopy analysis together high-resolution electron...
Carbon nitride (C3N4) is a layered, stable, and polymeric metal-free material that has been discovered as visible-light-response photocatalyst. Owing to C3N4 having higher conduction band position, most previous studies have focused on its reduction capability for solar fuel production, such hydrogen generation from water splitting or hydrocarbon production CO2. However, photooxidation ability of g-C3N4 weak less explored, especially decomposition chemically stable phenolics. spheres...

This work demonstrates a controlled van der Waals growth of two-dimensional SnTe nanoplates on mica substrates and their applications in flexible near-infrared photodetectors. The nonlayered rock-salt structured crystals into nanoplate structures is mainly caused by the nature surface, which also results ultrathin obtained (3.6 nm, equivalent to 6 monolayers). Furthermore, it found that shape can be well engineered changing temperature due competition between surface energy {100}...
Abstract Molecular surfactants are widely used to control low‐dimensional morphologies, including 2D nanomaterials in colloidal chemical synthesis, but it is still highly challenging accurately single‐layer growth for materials. A scalable stacking‐hinderable strategy not only enable exclusive mode transition metal dichalcogenides (TMDs) selectively sandwiched by surfactant molecules also retain TMDs' photoredox activities developed. The mechanism well explained theoretical calculation....
Abstract Phosphorus is an essential nutrient that thought to have regulated primary productivity in global oceans after the advent of oxygenic photosynthesis. The prime source seawater phosphorus regarded be continental weathering phosphate minerals. Ancient concentrations been constrained using content iron-rich chemical sediments—banded iron formations (BIFs); however, removal processes and depositional phases remain unclear. Here we report nanometer-sized apatite crystals (<500 nm)...
Abstract Economic gold deposits result from a 100- to 10,000-fold enrichment in relative crustal background. In hydrothermal systems, this is achieved through the transport and accumulation of metals via deeply sourced fluids site deposition. However, generally low metal solubility Au aqueous solutions orogenic systems requires additional processes order explain high-grade formation. Reports nanoparticles veins infer that their formation linked mineralisation. leading nanoparticle nucleation...
Magnesium oxide (MgO) thin films with sharp interfaces were deposited by sputtering of a Mg target on Si. The film stack was characterized using spectroscopic ellipsometry and transmission electron microscopy the static dielectric constant (κ) interface traps determined. An amorphous SiO2 layer found at MgO∕Si as result subcutaneous Si oxidation. κ for MgO to be about twice that SiO2, trap densities comparable SiO2∕Si, rendering competitive all presently considered high-κ dielectrics.
Metal nanoparticle (NP)–graphene multifunctional platforms are of great interest for exploring strong light–graphene interactions enhanced by plasmons and improving performance numerous applications, such as sensing catalysis. These can also be used to carry out fundamental studies on charge transfer, the findings lead new strategies doping graphene. There have been a large number noble metal Au–graphene Ag–graphene that shown their potential applications. highlighted some drawbacks must...
Electrode/electrolyte interface plays a critical role in the performance and stability of solid oxide fuel cells (SOFCs). Here, formation, Sr segregation reaction directly assembled La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode on barrier-layer-free Y2O3-ZrO2 (YSZ) electrolyte are studied at 1000 mAcm−2 750°C using focused ion beam scanning transmission electron microscopy (FIB-STEM) techniques. The results indicate that polarization promotes formation LSCF/YSZ with high level periodicity symmetry...
Apatite, rhabdophane and monazite are actinide- rare-earth element (REE)-bearing phosphate minerals with diverse geoscientific applications. However, their mineral-fluid reaction mechanisms below 200 °C understudied. Insufficient understanding as to how these behave during hydrothermal alteration impedes useful interpretations of REE-U-Th mobilisation in regolith profiles, diagenetic environments low-temperature systems. This work experimentally investigates the replacement apatite by a...
