Abstract Nowadays, mankind faces increasingly energy crisis and electromagnetic radiation pollution. An harvester with function of protecting human health from is a desirable solution to this problem. Here, stretchable shielding hybrid nanogenerator (ES‐HNG) reported which can not only scavenge thermal mechanical living environment but also protect monitor health. The ES‐HNG capable transforming electricity based on triboelectric, piezoelectric, pyroelectric effects. To be devised as...
Abstract We have engineered the electronic structure at interface between Cu 2 O and ZnO nanorods (NRs) array, through adjusting carrier concentration of O. The electrodeposition pH 11 acquired highest concentration, resulting in largest interfacial electric field ZnO, which finally led to separation efficiency photogenerated charge carriers. optimized O/ZnO NRs array p-n heterostructures exhibited enhanced PEC performance, such as elevated photocurrent photoconversion efficiency, well...
Magnetic tunnel junction (MTJ) embedded in complementary metal-oxide-semiconductor (CMOS) has been considered as one of the potentially powerful solutions to build up nonvolatile memory and logic circuits. It possesses many intrinsic merits, such high speed, instant on/off, good scalability low-leakage power, promises extend Moore's law. A critical issue this hybrid MTJ/CMOS structure is reliable integration MTJ electric signals CMOS electronics, especially for deep submicrometer technology...
Binderless tungsten carbide (WC) finds widespread applications in precision glass molding (PGM). Grinding and polishing are the main processes to realize optical surface finish on binderless WC mold inserts. The laser assisted turning (LAT) by in-process heating is an efficient method enhance machinability of hard brittle materials.

Abstract Rotating machinery (RM) serves as a critical component in modern industry, with widespread applications diverse sectors ranging from energy production to manufacturing processes. Fault diagnosis of RM is essential for preventing unexpected failures and enhancing overall equipment reliability. However, strong interference sources heavy environmental noise pose significant challenges fault Industry 4.0. Therefore, novel adaptive product cyclic spectrum (APCS) method proposed pattern...
A novel approach named off-spindle-axis (OSA) spiral grinding for fabricating aspheric microlens array (AMLA) mold inserts precision glass molding (PGM) is presented. In OSA grinding, three translational motions of the wheel are synchronized with rotation workpiece to form a local path individual lens-lets.

Precision glass molding technology is one of the most important approaches to produce optical lenses. However, high fidelity and repeatability performance be sometimes achieved even though lenses meet requirements geometric assessments. The surface errorform errors transferred from mold with a complicated combination components different spatial-frequencies greatly influence performance. An model built investigate impact form various frequencies on lens. mid-spatial frequency error proved...
Slow tool servo diamond turning has widespread application in fabricating freeform optics. Previous studies are focused on the methods of path generation and verification zero-rake-angle tools. However, these unsuitable for non-zero-rake tools that used machining hard-and-brittle materials. This paper presents a universal location-point-drive method, which caters to arbitrary rake angle steady X movement feature, corresponding interference check method. Systematic analysis ultra-precision...
Purpose The current research studies are inconclusive about the positive or negative effects of group faultlines, especially in Chinese context. To address this issue, study aims to adopt an interactive perspective explore interaction process. Specifically, proposes a new construct “interactive faultlines” integrate overall faultlines and separate based on categorization-elaboration model (CEM), develops integrated moderated mediation examine when how facilitate inhibit creativity....

Precision glass molding is the most appropriate method for batch production of lenses with high surface accuracy and qualified optical performance. However, form error caused by material expansion contraction main factor affecting precision molded lenses, thus mold must be pre-compensated. In this paper, an effective pre-compensation based on mathematical analysis established. Based thermal curve D-ZK3 glass, freezing fictive temperature under actual cooling rate measured, can quickly...
