Various modification strategies have been used to improve the physicochemical and biological properties of PEEK as orthopedic implants.

AgGaS2 (AGS) is the most commonly used commercial infrared nonlinear optical material. However, AGS has a narrow band gap (Eg = 2.58 eV) and low laser‐induced damage threshold (LIDT), primarily attributed to its mobile liquid‐like Ag+ constituent unstable Ag–S chemical bond. Herein, we propose “band reformation of AGS” strategy, which leads success syntheses four lanthanide sulfides, LiLnGeS4, crystalizing in an asymmetric Ama2 structure. LiLaGeS4 demonstrates that eliminating presence Ag‐4d...

Abstract In this work, continuous fiber reinforced thermoplastic negative Poisson's ratio structures (CFNPRSs) with rotating squares are fabricated by 3D printing based on a symmetrical orthogonal and one‐stoke path planning method. The influences of the ratio, elastic modulus energy absorption under compression systematically researched. distribution at hinge has great influence behavior structures. As number cross laps fibers increases, effect decreases while increase. printed CFNPRSs no...

Aspergillus niger has shown great potential for hexavalent chromium [Cr(VI)] bioremediation in wastewater treatment. However, the specific functional genes involved Cr(VI) removal pathway A. remain unexplored, limiting our ability to create genetically engineered strains with enhanced capabilities. In this study, we successfully identified two critical responsible chromate removal: chrR, a putative gene encoding reductase, and chrP, permease. Our findings revealed that deletion of either...

Abstract Birefringent crystals, which possess optical anisotropy, are important components. However, designing and synthesizing birefringent crystals faces the challenge of achieving anisotropic structures, especially coplanar geometries. Herein, we achieve a significant birefringence in an ionic compound (C 5 H 6 ON) + (NO 3 ) − , (4‐hydroxypyridinium nitrate, 4HPN) by hydrogen bonding between planar donors acceptors. We demonstrate that interactions bond donor ((C acceptor ((NO ensure...

Energy consumption of communication is a key factor the lifetimes wireless sensor networks. This paper presents an energy-efficient routing protocol for network. In protocol, each node detects distance between base station and itself. Then, it calculates tier ID in according to distance. A lower indicates shorter node. Nodes with higher IDs send data their neighbors IDs, where compressed forwarded toward nodes even tiers. Eventually reaches at lowest tier, then system selects sending...

This study utilizes data from Chinese A-share listed companies 2014 to 2022 theoretically analyze and empirically test the governance effect of ESG assurance on corporate greenwashing behavior, as well role played by legal environment management shareholding in this context. The impacts ownership mechanism behavior are also explored. employs text mining, OLS, PSM, IV-LIML, treatment models, feasible generalized least squares, placebo tests, bootstrap methods, etc., conduct empirical analysis...

Emotion AI is the ability of computers to understand human emotional states. Existing works have achieved promising progress, but two limitations remain be solved: 1) Previous studies been more focused on short sequential video emotion analysis while overlooking long video. However, emotions in videos only reflect instantaneous emotions, which may deliberately guided or hidden. In contrast, can reveal authentic emotions; 2) commonly utilize various signals such as facial, speech, and even...

In visual Reinforcement Learning (RL), upstream representation learning largely determines the effect of downstream policy learning. Employing auxiliary tasks allows agent to enhance in a targeted manner, thereby improving sample efficiency and performance RL. Prior advanced all focus on how extract as much information possible from limited experience (including observations, actions, rewards) through their different objectives, whereas this article, we first start another perspective:...

With the increasing application and demand of flexible AOLED display modules in global market, improving strength performance has important guiding significance for development OLED technology. In this paper, height falling ball is used as test index performance, influence composite structure on studied through combination with different thicknesses materials. It found that same thickness, using foam instead PI can obtain better results. The result silica gel material than material, overall...

Abstract This paper presents a new method for analyzing the free vibration characteristics of composite laminates under arbitrary boundary conditions by integrating generalized cells (GMC) and Two‐Dimensional Spectral‐Tchebychev (2D‐ST) method. First, meso‐macro correlation matrix is constructed based on GMC, macroscopic performance parameters are predicted. Then, virtual springs introduced to simulate conditions, energy equation laminate derived first‐order shear deformation theory (FSDT)...
