Ultrafast 4D printing (<30 s) of responsive polymers is reported. Visible-light-triggered polymerization commercial monomers defines digitally stress distribution in a 2D polymer film. Releasing the after converts structure into 3D. An additional dimension can be incorporated by choosing precursors. The process overcomes speed limiting steps typical 3D (4D) printing.
Abstract Switchable optical properties are essential for numerous technologies including communication, anticounterfeiting, camouflage, and imaging/sensing. Typically, the switching is enabled by applying external stimulation such as UV light fluorescence detection. In contrast, ground squirrels utilize spontaneous live infrared emission fencing off predators a unique way of communication. Inspired this, evolution both thermal images temporal communication in which time encoded information...
Low-dimensional organic–inorganic hybrid perovskites (OIHPs) have shown significant potential in the optoelectronic field due to their adjustable structure and properties. However, poor air stability flexibility of OIHP crystals limit further development. Herein, three been synthesized using cadmium chloride isomer phenylenediamine as raw materials. Mn2+ doping turns on red-light emission Cd-based OIHPs at around 625 nm. Interestingly, organic ligands with different steric hindrance can...
Abstract Herein, a coordination trap strategy is proposed for constructing stimulus‐responsive phosphorescent perovskites. Hydroxyl groups are selected as and introduced into benzylamine hydrochloride of Cd‐based perovskite. The resulting two‐dimensional (2D) perovskite (C 7 H 10 NO) 2 CdCl 4 ·H O (H1) exhibits blue fluorescence at 405 nm green phosphorescence 482 under 365 excitation. After introducing guest Mn 2+ , due to the passivation defects, doped H1 (H1‐M) achieves orange ( λ = 615...
Numerous factors can influence the growth, reproduction, and metabolism of microbes, which yield production cost. Bacillus sp. EtOH is a bacterial strain with high ethanol. In this paper, medium was optimized. Different carbon/nitrogen sources were investigated, best carbon source (sucrose) nitrogen (ammonium sulfate) determined to improve ethanol production. addition, initial pH, temperature, inoculation volume 7, 37 ° C 1%, respectively. This study will be conducive subsequent...
Studies examining the effects of social participation on activities daily living (ADL) disability are still scarce.
Abstract Background Cognitive leisure activity, such as reading, playing mahjong or cards and computer use, is common among older adults in China. Previous studies suggest a negative correlation between cognitive activity impairment. However, the relationship all-cause mortality has rarely been reported. Objectives This study aims to explore relationships community-based people cohort Methods The current sample comprised 4003 community residents aged ≥60 y who were enrolled June 2015,...

Since many target features can be acquired via inverse synthetic aperture radar (ISAR), the key of implementing deception jamming on ISAR lies in inducing decoy images imitating scattering real target. In this paper, based combination frequency diverse array (FDA) and scatter-wave (SWJ), an approach producing multiple two-dimensional with is presented, distribution number which arbitrarily manipulated through designing FDA parameters. Details provided along simulation results, illuminates...
Most of the existing deception jamming methods can only achieve effective on one dimension. Thus, a two-dimensional method for SAR imaging based frequency diverse array (FDA) and micro-motion modulation is proposed in this paper. The produce number false targets both range azimuth image, location which be specifically controlled. Based geometry, principles are derived. According to final image expression, performance with different parameters demonstrated. Experimental results illuminate...
This paper is devoted to the research of methods and experiments regularization deconvolution theory on azimuth super-resolution forward-looking imaging radar. L1 norm usually used as a regular term obtain stable solution due its strong resolving power for sparse targets. However, an ill-posed problem, in process iteration, using sensitive noise may causes large deviation between true value influence noise. proposes method combined truncation singular decomposition (TSVD) with constraint. At...
