Open AccessUltra-sensitive, highly linear, and hysteresis-free strain sensors enabled by gradient stiffness sliding strategy
Develo** strain sensors with both high sensitivity and high linearity has always been the goal of researchers. Compared to resistive strain sensors, capacitive strain sensors have incomparable linearity adva...

Open AccessMXene-reduced graphene oxide sponge-based solar evaporators with integrated water-thermal management by anisotropic design
The main issue limiting the performance of the solar evaporators is that water-thermal management is difficult to coordinate. Herein, we achieve integrated water-thermal management by designing hierarchical MX...

Superbroad-band actively tunable acoustic metamaterials driven from poly (ethylene terephthalate)/Carbon nanotube nanocomposite membranes
Actively tunable acoustic metamaterials have attracted ever increasing attention. However, their tunable frequency range is quite narrow (tens of Hz) even under ultrahigh applied voltage (about 1,000 V). Here,...

Super resolution for astronomical observations
In order to obtain detailed information from multiple telescope observations a general blind super-resolution (SR) reconstruction approach for astronomical images is proposed in this paper. A pixel-reliability...

Parameter optimization of multi-pass multi-layer MIG welded joint for invar alloy
A multi-pass multi-layer automatic MIG welding technology was used to joint invar alloy. The detection results of energy-dispersive spectroscopy (EDS) and X-ray diffraction for the welded joints showed that th...

Carbon nanotube-polypyrrole core-shell sponge and its application as highly compressible supercapacitor electrode
A carbon nanotube (CNT) sponge contains a three-dimensional conductive nanotube network, and can be used as a porous electrode for various energy devices. We present here a rational strategy to fabricate a uni...

Detection of Faint Objects between Streak-Like Stellar Images
In this paper we propose a novel method based on the characteristics of the object that we are interested in to distinguish it from other stars, whose images are line-shaped trails. The point-like object and s...

Accurate determination of the plate model based on CCD images with different orientations
The images of the open cluster NGC2168 are taken using the newly-fitted 2k×2k CCD attached to the 1-m telescope at the Yunnan Observatory with two different orientations. After the catalogue position of a star fr...

Image-processing techniques in precisely measuring positions of Saturn and its satellites
After overcoming the deficiencies of previous image-processing techniques, a novel technique based on the edge-detection of Saturnian ring is developed to precisely measure Saturn’s position. Furthermore, the ...
