Chronic diabetic wounds have become a major healthcare challenge worldwide. Improper treatment may lead to serious complications. Current methods including biological and physical skin grafting limitations disadvantages, such as poor efficacy, inconvenience of use, high cost. Therefore, developing more effective feasible is great significance for the repair chronic wounds. Hydrogels can be designed serve multiple functions promote Furthermore, 3D bioprinting enables hydrogel customization...
Owing to the innate good biocompatibility, tissue-like softness and other unique properties, hydrogels are of particular interest as promising compliant materials for biomimetic soft actuators. However, actuation diversity hydrogel actuators is always restricted by their structure design fabrication methods. Herein, origami structures were introduced fluid-driven achieve diverse movements, a facile strategy based on removable templates inside-out diffusion-induced in situ crosslinking was...
We propose a method to design compact circularly polarized (CP) antenna using novel sunshine-shaped slotted radiating patch, which exhibits slow wave and other interesting properties. The structured patch introduces adjustable coupling between pair of orthogonal modes (TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> mode TM xmlns:xlink="http://www.w3.org/1999/xlink">01</sub> mode) facilitate good axial ratio (AR) reflection...
Abstract Hydrogels are characterized by high water content and typically used in environments. However, when air environments, hydrogels face limitations due to instability caused loss. This study reports the development of PAM/glycerol with improved stability. By using water–glycerol bi‐solvents lock internally, a closed environment was established reduce exchange outside world. The hydrogel made forming single PAM crosslinking network UV crosslinked acrylamide (AM) monomer. weight varied...
Abstract A method of designing two‐element compact multiple‐input and multiple‐output (MIMO) antennas with good isolation based on slow‐wave corrugated strips (CSs) is presented in this paper. Using the characteristic, a pair CSs applied as arms each dipole antenna element to realise design. metal plane placed between two dielectric boards serving reflector so that can achieve forward radiation. There are coupling paths closely antennas: adjacent reflector. By adjusting phase constants...
A new method of designing compact dipole antenna based on surface polarized plasmon (SPP) structure, is proposed in this paper. To realize the design, we take advantage slow wave character SPP to design arms antenna. While, radiation pattern operating band not change too much against conventional one. The are fed by microstrip line. Besides, ground plane plays role reflector, thus obtaining a good forward gain Afterwards, antenna, whose working 3.54-3.57GHz designed verify effectiveness...
Abstract Cold compressors are the core component needed for development of a facility large-capacity refrigeration at superfluid helium temperatures. The compressor impeller is operated extremely low temperature and pressure which involves technical issues including material properties temperature, heat transfer, failures actuating motor resulting from overheating performance penalty due to transfer warm side machine cold side. To address these issues, it important understand distribution...
Programming electromagnetic spectra have become key technology affecting the development of information industry, arousing widespread interest researchers. Here, we propose a route to realize programmable spectrum based on time-coding spoof surface plasmon polaritons (SSPPs) implement customized harmonic generations and amplitude manipulations. The proposed SSPPs are experimentally demonstrated flexibly control both frequencies amplitudes harmonics, providing possibility reprogrammable...
Abstract A design method of compact wideband balun bandpass filter (BPF) with high selectivity based on corrugated slot is proposed here. To realize response in size, metal strips are deployed parallel to the half‐mode (HMCS). Besides, coupling stripline provides conversion microstrip structure at balanced ports.

Abstract Continuous on-line fuel cycling is the essential feature of pebble bed high temperature reactor (PB-HTR). The flow speed pebbles in a PB-HTR presents radial distribution core, mainly due to friction between and wall conical structure at core bottom. In VSOP shuffling model, simulation unequal achieved by dividing into some vertical channels with different numbers equal-volume regions each channel. However, batches bring complexity when dealing change composition, such as fraction...
