Although eco-friendly amidoxime-based adsorbents own an excellent uranium (U)-adsorption capacity, their U-adsorption efficiency is commonly reduced and even damaged by the biological adhesion from bacteria/microorganisms in aqueous environment. Herein, we present antibiofouling ultrathin poly(amidoxime) membrane (AUPM) with highly enhanced performance, through dispersing quaternized chitosan (Q-CS) a cross-linked sulfonated cellulose nanocrystals (S-CNC) network. The S-CNC not only can...
Abstract Although diverse uranium (U) adsorbents have been explored, it is still a great challenge for high-efficient extraction form seawater.

Compared α-SiC, β-SiC performs better in Pd@β-SiC(APTES + CIT) exhibits...
We propose and demonstrate experimentally the generation of chaos with suppressed time-delay signature (TDS) physical random bits in two mutually coupled semiconductor lasers (MCSL) by introducing an auxiliary fiber Bragg grating (FBG) filtered injection path. The measurements show that, even simply adding a single FBG path, TDS chaotic signals generated both our proposed scheme can be better concealed compared to conventional MCSL system. Moreover, concealment achieved laser smaller...

Abstract Building long-lasting antimicrobial and clean surfaces is one of the most effective strategies to inhibit bacterial infection, but obtaining an ideal smart surface with highly efficient, controllable, regenerative properties still encounters many challenges. Herein, we fabricate ultrathin brush–hydrogel hybrid coating (PSBMA-P(HEAA- co -METAC)) by integrating antifouling polyzwitterionic (PSBMA) brushes polycationic (P(HEAA- hydrogels. The killing–releasing can be achieved...
Stimuli-responsive color-changing and shape-changing hydrogels are promising intelligent materials for visual detections bio-inspired actuations, respectively. However, it is still an early stage to integrate the performance together provide bi-functional synergistic biomimetic devices, which difficult design but will greatly expand further applications of hydrogels. Herein, we present anisotropic bi-layer hydrogel by combining a pH-responsive rhodamine-B (RhB)-functionalized fluorescent...
Stimuli-responsive actuating hydrogels response to the external stimulus with complex deformation behaviors based on programmable anisotropic structure design are one of most important smart soft materials, which have great potential applications in artificial muscles, values, and mini-robots.

A novel image encryption algorithm using the random fractional DCT (RFrDCT) and chaos-based Game of Life (GoL) is presented here. Firstly plaintext transformed by reality-preserving RFrDCT into domain, a preliminary output obtained. And then combination confusion diffusion (C&D) processes performed in transform where process carried out GoL, an XOR operation. Therefore more random-like result can be obtained after further C&D. Both GoL operation are based on chaos whose control parameters...
As one of the most important anisotropic intelligent materials, bi-layer stimuli-responsive actuating hydrogels have proven their wide potential in soft robots, artificial muscles, biosensors, and drug delivery. However, they can commonly provide a simple one-actuating process under external stimulus, which severely limits further application. Herein, we developed new hydrogel actuator by local ionic crosslinking on poly(acrylic acid) (PAA) layer for sequential two-stage bending single...
Stimuli-responsive actuating hydrogels, with "soft and wet" state, are most important intelligent materials, which have been widely applied in more fields. However, the natural isotropic structure high water-content of hydrogels leads to relatively simple mode weak mechanical performance respectively, severely limit further applications hydrogels. To solve these problems, this study has developed a new hydrogel skin-mimetic anisotropic structure. Based on supramolecular interaction,...

Dementia is a neurodegenerative disease with high incidence in the elderly. However, there no effective treatment for this disease, and early intervention has great effect to slow deterioration. Currently, detection of dementia mainly achieved using questionnaire-like neuropsychological tests. Such ways usually cost lot time.
