Virtual Coriolis-Force-Based Mode-Matching Micromachine-Optimized Tuning Fork Gyroscope without a Quadrature-Nulling Loop.

A VCF-based mode-matching micromachine-optimized tuning fork gyroscope is proposed to not only maximize the scale factor of the device, but also avoid use of an additional quadrature-nulling loop to prevent structure complexity, pick-up electrode occupation, and coupling with a mode-matching loop. In detail, a mode-matching, closed-loop system without a quadrature-nulling loop is established, and the corresponding convergence and matching error are quantitatively analyzed. The optimal straight beam of the gyro structure is then modeled to significantly reduce the quadrature coupling.

1D/1D WO/CdZnS S-scheme heterojunction with spatial charge separation for high-yield photocatalytic H evolution.

Semiconductor photocatalytic water splitting is a green way to convert solar energy into chemical energy, but the recombination of electron and hole pairs and the low utilization of sunlight restrict the development of photocatalytic technology. By comparing the morphologies and hydrogen production properties of different proportions of solid solutions (CdZnS), one-dimensional (1D) CdZnS nanorods (NRs) with the best photocatalytic properties are obtained. In addition, 1D WO nanowires are assembled on the surface of 1D CdZnS NRs to construct a novel 1D/1D step-scheme (S-scheme) WO/CdZnS heterojunction photocatalyst.

Porous graphitic carbon nitride with nitrogen defects and cobalt-nitrogen (CoN) bonds for efficient broad spectrum (visible and near-infrared) photocatalytic H production.

The porous graphitic carbon nitride (g-CN) with nitrogen defects and cobalt-nitrogen (CoN) bonds (g-CN-Co-K) is prepared by controllable copolymerization of melamine with KOH and Co(NO)·6HO. The method not only provides g-CN with porous structure and CoN bonds that accelerate photoexcited carrier transfer and endow numerous active sites, but also redshifts the g-CN absorption edge into near-infrared (NIR) light region through the introduction of nitrogen defects and thus is suitable for H evolution. The g-CN-Co-K exhibits significantly superior photocatalytic hydrogen generation performance (808 µmol h g) under simulated solar light irradiation, about 15.
