TL;DR: In this article , the authors reported an ultrahigh electromagnetic interference (EMI) SSE/t value (>106 dB cm2/g) using a conductive CuS nanosheet with thickness less than 20 nm.
Abstract: Electronic devices in highly integrated and miniaturized systems demand electromagnetic interference shielding within nanoscale dimensions. Although several ultrathin materials have been proposed, satisfying various requirements such as ultrathin thickness, optical transparency, flexibility, and proper shielding efficiency remains a challenge. Herein, we report an ultrahigh electromagnetic interference (EMI) SSE/t value (>106 dB cm2/g) using a conductive CuS nanosheet with thickness less than 20 nm, which was synthesized at room temperature. We found that the EMI shielding efficiency (EMI SE) of the CuS nanosheet exceeds that of the traditional Cu film in the nanoscale thickness, which is due to high conductivity and the presence of internal dipole structures of the CuS nanosheet that contribute to absorption due to the damping of dipole oscillation. In addition, the CuS nanosheet exhibited high mechanical stability (104 cycles at 3 mm bending radius) and air stability (25 °C, 1 atm), which far exceeded the performance of the Cu nanosheet film. This remarkable performance of nanometer-thick CuS proposes an important pathway toward designing EMI shielding materials for wearable, flexible, and next-generation electronic applications.

Abstract: In this paper, a simple fabricated and low cost acoustic vibration sensor based on macro-bend coated single-mode fiber (SMF-28) is proposed and developed. The fiber optic sensor comprises of a bending structure and the macro-bending loss was employs as the sensing mechanism for the detection of leakage of pipeline at low frequency. The measurement system involving the proposed fiber sensor is presented and investigated. Through this system, the fiber sensor is characterized by measuring the power loss corresponding to the vibration at various bending radius and number of wrapping turns. Furthermore, the proposed fiber sensor is also implemented in field test (water pipeline) and it is able to detect vibrations at the frequency range of 20 Hz to 2500 Hz.

TL;DR: A sheathing for optical fibres and for optical fibre cables comprises a continuous length of tubing with the tubing walls being designed to allow the tube to be bent to a predetermined radius but to hinder its bending to a radius smaller than the predetermined radius.
Abstract: A sheathing for optical fibres and for optical fibre cables comprises a continuous length of tubing with the tubing walls being designed to allow the tube to be bent to a predetermined radius but to hinder its bending to a radius smaller than the predetermined radius. The tube walls (12) include portions (18) which are spaced apart when the tube is straight, but abut one another at (20) when the tube is bent to the predetermined radius.

TL;DR: In this paper, the elastic strain in the crystal wafer is partially released by a "strip-bent" method where the crystal was cut in strips prior to the bending and the anodic bonding process.
Abstract: We present the development, manufacturing and performance of spherically bent crystal analyzers (SBCAs) of 100 mm diameter and 0.5 m bending radius. The elastic strain in the crystal wafer is partially released by a "strip-bent" method where the crystal wafer is cut in strips prior to the bending and the anodic bonding process. Compared to standard 1 m SBCAs, a gain in intensity is obtained without loss of energy resolution. The gain ranges between 2.5 and 4.5, depending on the experimental conditions and the width of the emission line measured. This reduces the acquisition times required to perform high energy-resolution x-ray absorption and emission spectroscopy on ultra-dilute species, accessing concentrations of the element of interest down to, or below, the ppm (ng/mg) level.
