Abstract Utilizing N₂ from the air and water for electrocatalytic nitrogen reduction reaction shows promise NH₃ synthesis under mild conditions. However, chemical stability of thermodynamic limitations hinder its effectiveness. Herein, we integrated a specially designed Cu nanowire catalyst with five‐fold twin structure (T‐CuNW) into an system, combining nonthermal plasma‐assisted activation. This work achieved yield 45 mg·mg cat. −1 ·h Faradaic efficiency over 95% at −0.5 V versus RHE after...
Recent advances in single-cell multi-omics have provided unprecedented insights into gene regulation by jointly profiling transcriptomic (scRNA-seq) and chromatin accessibility (scATAC-seq) landscapes. However, the inherent heterogeneity high dimensionality of these multimodal data present significant challenges for effective integration downstream analysis. Foundation models demonstrated strong representation learning capabilities scRNA-seq or scATAC-seq data. So far, however, no model has...
The severe vibration of a screw compressor outlet piping system caused the premature failures some thermowells and unplanned shut down system. root causes problem were investigated by numerical simulations. An acoustic model was established to predict pressure pulsation gas inside pipelines, two finite element models built study characteristics overall thermowells. results indicated that may be attributed excessive nonuniformity low stiffness first-order structural resonance occurred on A...
This paper presents the root cause analysis and solving process of torsional vibration problem in a reciprocating compressor shaft system. The field measured data showed that fifth-order resonance occurred lumped-mass method was adopted to calculate natural frequencies (TNFs) mode shapes A sensitivity study conducted investigate effect each inertia stiffness calculation model on first TNF uncertainties primary were discussed, mass-elastic modified by adjusting flexible disc coupling. After...
The averaging principle is established for the slow component and fast being two dimensional stochastic Navier-Stokes equations reaction-diffusion equations, respectively. classical Khasminskii approach based on time discretization used proof of strong convergence to solution corresponding averaged equation under some suitable conditions. Meanwhile, powerful techniques are overcome difficulties caused by nonlinear term release regularity initial value.
In DC microgrids, the piecewise droop control is an advanced coordinative strategy, realizing plug-and-play capability of parallel converters and improved bus voltage regulation. However, it difficult to realize smooth accurate switch among different curves. The traditional hysteresis-based fails curves when difference line resistances not negligible. To handle this issue, paper proposes adaptive strategy reliably. First, architecture basic principle proposed are illustrated. Then,...
This paper presents the substructure-based dynamic analysis of an offshore platform with compressor packages. Three typical substructure methods, Guyan condensation method, fixed-interface component mode synthesis (CMS) method and free-interface CMS were compared to identify appropriate for this application. A truncation criterion was proposed ensure accuracy recommended method. The results indicated that could generate almost same as fully coupled save more than 50% in calculation time 60%...
Abstract An improved Wiener path integral (WPI) approach is developed for predicting the stochastic response probability density functions (PDFs) of nonlinear systems under non-white excitation. Specifically, excitation process modeled as output a filter whose input Gaussian white noise, joint PDF system expressed functional action over space all possible trajectories between initial and final states, second-order variation recast to quadratic form taken into account in estimation PDF....
Reciprocating compressor packages are key equipment for the offshore platforms which used pressurization and transportation of natural gas.

Cell membrane biomimetic platform is a promising candidate for screening small molecule compounds from natural products to address the challenge of P-Glycoprotein (P-gp) mediated cancer multidrug resistance (MDR). However, randomly oriented cell coating does not guarantee inward-opening conformation P-gp, limiting precise P-gp inhibitors. Herein, inside-out orientation extracellular vesicles camouflaged magnetic nanoparticles (IOVMNPs) were prepared discover inhibitors with low toxicity and...
