Two-dimensional Si6H6 nanosheets are prepared via exfoliation of CaSi2 using chemical stripping method. After reacting with AgNO3-aniline complex and carbonizing, the SiOx/C-Ag nanosheets electrode exhibits high capacity and long-term cycling stability when served as anode materials in lithium-ion battery.

The supported 30 nm WTe2 encased with 70 nm Al2O3 delivered 4.8 and 3.0 W·m−1·K−1 in-plane thermal conductivity along zigzag and armchair directions at room temperature, in which the waste heat in WTe2 would be mostly dissipated to metal contacts located along zigzag for relieving the local temperature discrepancy in the channel effectively and preventing degradation or breakdown.

A perceptual sensory system is developed from the inspiration of biological olfaction function. Analog signals from the gas sensor is converted to pulse-like physiological signals by the flexible oscillator, and further processed by the artificial synapse. The recognition accuracy of the gas with a given concentration is enhanced by repeating training, illustrating a great potential in mimicking biological cognitive functions.

Surface hole trap is a critical factor that limits photocatalytic activity of La2Ti2O7. With the deposited Co-Pi and Pt co-catalysts for holes and electrons transfer, overall water splitting can be achieved on Bi-doped La2Ti2O7 due to the passivated hole-trapping by Bi doping and accelerated hole-injection to water by Co-Pi deposition.

A new and facile strategy for directly synthesizing monodisperse ordered FePt nanoparticles (NPs) with average size 10.7 nm without further annealing or doping the third element was developed. The L10-FePt NPs synthesized by this approach show a coercivity of 3.15 kOe and saturation magnetization of 45 emu/g at roomtemperature.

Our study resolves the debate that nano-sized Ag rather than singleatom Ag determines CO oxidation activity and stability by using combined experimental measurements, instrument characterizations and density functional theory (DFT) calculations. Superior oxygen activation ability and the valence stability are conducive to the advantages of Ag nanoparticles in the CO oxidation reaction.

The growth of different phases of layered ferromagnetic iron germanium telluride (FexGeTe2) via a new chemical vapor deposition (CVD) method is shown in this work. Fe5GeTe2 displays near room temperature TC with out-of-plane ferromagnetic ordering and exhibits a two-dimensional (2D) Ising to three-dimensional (3D) XY magnetic critical behavior transition.
