Fibrous material with high strength and large stretchability is an essential component of high-performance wearable electronic devices. Wearable systems require a that strong to ensure durability stability, wide range strain expand their applications. However, it still challenging manufacture fibrous materials simultaneously mechanical the tensile property. Herein, ultra-robust (≈17.6 MPa) extensible (≈700%) conducting microfibers are developed demonstrated applications in fabricating...
The advancement of contemporary X-ray imaging heavily depends on discovering scintillators that possess high sensitivity, robust stability, low toxicity, and a uniform size distribution. Despite significant progress in this field, the discovery material satisfies all these criteria remains challenge. In study, we report synthesis monodisperse copper(I)-iodide cluster microcubes as new class scintillators. as-prepared exhibit remarkable sensitivity to X-rays exceptional stability under...
Real-time thermal sensing through flexible temperature sensors in extreme environments is critically essential for precisely monitoring chemical reactions, propellant combustions, and metallurgy processes. However, despite their low response speed, most existing related materials will degrade or even lose performances at either high temperatures. Achieving a microsecond time over an ultrawide range remains challenging. Here, we design sensor that employs ultrathin consecutive Mo 1− x W S 2...
This work proposes a design, fabrication, and characterization of flexible temperature sensors using temperature-sensitive materials, which are applied drop coating method. Temperature-sensitive materials were fabricated by mixing poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) with polyaniline (PEDOT:PSS/PANI). The coefficient resistance reached −0.803%/°C. Moreover, the detection resolution 0.1 °C had fast response time 200 ms. In addition, sensor can sense spatial temperatures....
Flexible and wearable pressure sensors attached to human skin are effective convenient in accurate real-time tracking of various physiological signals for disease diagnosis health assessment. Conventional flexible constructed using compressible dielectric or conductive layers, which electrically sensitive external mechanical stimulation. However, saturated deformation under large compression significantly restrains the detection range sensitivity such sensors. Here, we report a novel type...

This study aims to prepare in situ textures with effective density their mechanism on surface ductile cast iron, which optimizes tribological properties crankshafts reduces wear. Design/methodology/approach A new method was proposed based hardness difference graphite removal form an texture. friction performance evaluated using a combination computational fluid dynamics testings. influence texture...
Clostridium perfringens is an important foodborne pathogen, which has caused serious public health problems worldwide. So, there urgent need for rapid and ultrasensitive detection of C. perfringens. In this paper, a dual-mode sensing platform using the synergy between fluorescent electrochemical signals was proposed. An aptasensor constructed by dual-amplification technology based on DNA walker hybridization chain reaction (HCR). When genomic present, it specifically bonded with FAM-labeled...
We disclose herein a chiral phosphoric-acid-catalyzed enantioselective addition reaction of alcohols to fluoroalkylated biaryl 1,3-oxoazepines, which furnished wide range bridged biaryls bearing quaternary carbon stereocenter on the seven-membered ring in high yields (up 99%) with excellent enantioselectivities 98% ee). Our method can be used for modification several natural products and bioactive molecules. Preliminary studies revealed that obtained this exhibit good vitro bioactivities...
The two-dimensional (2D) transition metal dichalcogenides (TMDs) are promising flexible electronic materials for strategic information devices. Large-area and high-quality patterned were usually required by electronics due to the limitation from process of manufacturing integration. However, synthesis large-area 2D TMDs with high quality is difficult. Here, an efficient powerful pulsed laser has been developed synthesize wafer-scale MoS2. strain sensor was fabricated using MoS2 showed...
This paper develops a hybrid experimental/simulation method for the first time to assess thermal stresses generated during electron beam melting (EBM) at high temperatures. The bending and rupture of trusses supporting Inconel 625 alloy panels ~1050 °C are experimentally measured various scanning strategies. strains thereafter simulated using Finite-Element Method (FEM). It is shown that on may reach material UTS without causing failure. Failure only reached after part experiences certain...
