ABSTRACT Flexible sensors exhibit the properties of excellent shape adaptability and deformation ability, which have been applied for environmental monitoring, medical diagnostics, food safety, smart systems, human–computer interaction. Cellulose‐based hydrogels are ideal materials fabrication flexible due to their unique three‐dimensional structure, renewability, ease processing, biodegradability, modifiability, good mechanical properties. This paper comprehensively reviews recent advances...

Sorption-based atmospheric water harvesting (SAWH) shows great promise to mitigate the worldwide scarcity, especially in arid regions. Salt-based composite materials are extensively used sorbents for SAWH, however, they suffer from complex preparation avoid salt leakage. Furthermore, significant amount of heat produced during process is often neglected and wasted. Herein, an integrated strategy developed synthesis salt-based stable super moisture-sorbent sponge by using chelation LiCl...

Shape and surface topography evaluation from measured orthogonal slope/gradient data is of considerable engineering significance since many full-field optical sensors interferometers readily output such a accurately. This has applications ranging metrology electronic elements (lenses, silicon wafers, thin film coatings), profile estimation, wave front shape reconstruction, to name few. In this context, new methodology for stress field determination based on recently introduced non-contact,...

Surface topography evaluation from measured surface slopes is critical in many engineering applications, including metrology of electronic substrates, optical elements, and small deformation measurement structures subjected to external thermomechanical stimuli. A recently proposed noncontact full-field method called reflection-mode digital gradient sensing (r-DGS) able measure angular deflections light rays proportional two orthogonal slopes. It has been shown that submicron scale...

Abstract A new type of ceramic armor structure is designed by using spherical cylindrical splice plate as panel with metal steel frame applied, TC4 titanium alloy and 685 back respectively in this paper. Ballistic test was carried out firing 14.5mm penetrator projectile ballistic gun. Results show that: damage area smaller when the weight lighter aftereffect similar, performance better than that conventional composite structure, which has certain advantages anti-multiple capability; density...

Abstract In this paper, the mechanical properties of pre-cracked high nitrogen steel specimens with different loading angles 30°, 45° and 60° were studied by using Hopkinson tension bar. The corresponding force-displacement curves under obtained. It was found that decrease pre-crack angle, proportion shear stress on in composite gradually increased, concentration appeared during process, fracture strength decreased significantly. At same time, however, dispersion experimental results...
