Correlating metal-organic framework (MOF) synthesis processes and microwave absorption (MA) enhancement mechanisms is a pioneer project. Nevertheless, the correlation process still relies mainly on empirical doctrine, which hardly corresponds to specific mechanism of effect dielectric properties. Hereby, after strategy modulation protonation engineering solvothermal temperature in route, obtained sheet-like self-assembled nanoflowers were constructed. Porous structures with multiple...

Microwave Absorption In article number 2302633, Zhengjun Yao, Jintang Zhou, Ping Chen, and co-workers utilize protonation engineering solvent thermodynamic modulation strategies to controllably design sheet-like self-assembled nanoflowers. The controlled of the synthetic routes results in structures with multiple heterogeneous interfaces, abundant defects vacancies. A correlation model between synthesis process metal–organic framework (MOF)-derived materials microwave loss mechanism is...

We investigate in detail the properties of stationary quantum steering two mechanical modes, where modes interact with coupling cavity and four-tone driving lasers are used to pump modes. By controlling pumping lasers, can act as engineered reservoirs cool a squeezed state. When damping rates different, numerical simulation results show that there parameter regions state only has one-way steering, which is most prominent feature from entanglement.

Apples are one of the most important economic crops worldwide. Because global warming and an aggravation environmental, abnormally high temperatures occur frequently in fruit-growing season seriously affect normal fruit growth reduce quality yield. We took five-year-old 'Ruixue' (Qinfu 1 × Pink Lady; CNA20151469.1) fruits as test materials, ambient temperature during development was monitored. The results showed that season, especially rapid stage (July to August), maximum daily exceeded 30...

Quantum synchronization and its connection with other quantum correlations have attracted considerable attention. Here we present a theoretical scheme to simultaneously represent significantly enhance the level of entanglement between two indirectly coupled mechanical membranes, which are common optical field within cavity. By applying two-tone driving laser weighted amplitudes specific frequencies, both gauged by Mari's criterion estimated logarithmic negativity can be greatly enhanced. We...

Capillary forces of a shearing liquid bridge can significantly affect the friction and adhesion interacting surfaces, but underlying mechanisms remain unclear. We custom built surface force apparatus (SFA, ±2 μN) equipped with in situ optical microscopy performed normal lateral measurements on reciprocating water formed between two flat plates. A modified wedge method was developed to correct unique measurement errors caused by changing geometry position. The results found (1) strong linear...

This paper presents a simplified space vector pulse width modulation (SVPWM) method for multilevel converters based on line voltages coordinate system. In the proposed SVPWM technique, solution of working vectors and their dwelling time are simplified. order to flexibly obtain different switching sequences, nearest-level (NLM) principle is applied. Hence, only one three wording needs be detected. The algorithm independent level numbers generated redundant sequences can used improve potential...

A novel trench shielded planar gate IGBT (TSPG-IGBT) with self-biased pMOS is proposed in this paper. It features a P-layer beneath the of TSPG-IGBT to form pMOS, which provides an additional path for hole current and clamps potential nMOS's intrinsic drain lower saturation current. In off-state, increasing N-cs (N-doped carrier store layer), turns on will be clamped by channel. Then, reverse voltage sustained P-layer/N-drift junction region. Therefore, can heavily doped reduce on-state...

Loading during the high velocity compaction (HVC) of metal powder generates high-speed impact. Thus, dynamic stress rapidly changes, and its propagation properties exert an important influence on densification. In this investigation, progress HVC is simulated using a discrete element method, characterized by distribution variation Y-direction along height direction. The influences impact velocity, initial porosity, friction coefficient are analyzed. Results show that in represents upper...
