Tungsten diselenide (WSe2) possesses extraordinary electronic properties forapplications in electronics, optoelectronics, and emerging exciton physics. Thesynthesis of monolayer WSe2 film is of topmost for device arrays and integratedcircuits. The monolayer WSe2 film has yet been reported by thermal chemicalvapor deposition (CVD) approach, and the nucleation mechanism remainsunclear. Here, we report a pre-seeding strategy for finely regulating the nucleidensity at an early stage and achieving a fully covered film after chemicalvapor deposition growth. The underlying mechanism is heterogeneous nucle-ation from the pre-seeding tungsten oxide nanoparticles. At first, we optimized the precursor concentration for pre-seeding. Besides, we confirmed the superi-ority of the pre-seeding method, compared with three types of substrate pre-treatments, including nontreatment, sonication in an organic solvent, andoxygen plasma. Eventually, the high-quality synthetic WSe2 monolayer filmexhibits excellent device performance in field-effect transistors and photodetec-tors. We extracted thermodynamic activation energy from the nucleation andgrowth data. Our results may shed light on the wafer-scale production ofhomogeneous monolayer films of WSe2, other 2D materials, and their van derWaals heterostructures.

Reversible regulation of membrane microstructures via non-covalent interactions is of considerable interest yet remains a challenge. Herein, we discover a general one-step approach to fabricate supramolecular porous polyelectrolyte membranes (SPPMs) from a single poly(ionic liquid) (PIL). The experimental results and theoretical simulation suggested that SPPMs were formed by a hydrogen-bond-induced phase separation of a PIL between its polar and apolar domains, which were linked together by water molecules. This unique feature was capable of modulating microscopic porous architectures and thus the global mechanical property of SPPMs by a rational design of the molecular structure of PILs. Such SPPMs could switch porosity upon thermal stimuli, as exemplified by dynamically adaptive transparency to thermal fluctuation. This finding provides fascinating opportunities for creating multifunctional SPPMs. © 2020 Wiley-VCH GmbH

In this study, simultaneous adsorption of heavy metals was examined by using binary component solutions. Microcrystalline cellulose (MCC) was used as an adsorbent for heavy metal uptake of heavy metal (Copper (Cu2+) and Ferum (Fe2+)) from aqueous solution in binary system. The result of adsorption experiment revealed that MCC presented more than 70% adsorption of Cu2+ and Fe2+ at high heavy metals solution and pH. It proposed that there are sturdy electrostatic attractions among the surface of the adsorbent and cationic heavy metal ions. Also, the kinetic studies for sorption of Cu2+ and Fe2+ onto MCC were better signified by a pseudo-second-order (PSO) model, which demonstrates chemisorption between the polymeric MCC adsorbent and heavy metal molecules. Bestowing to investigational findings, MCC is an attractive adsorbent for treatment of wastewater containing multiple heavy metal ions.

Herein, screen printed electrodes prepared from commercially available conducting polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate have been shown to record simultaneous electromyogram (EMG), electrocardiogram (ECG), and electrodermal activity (EDA) from a spandex t-shirt sleeve in dry state. Secondly, electrodes printed on an arm sleeve recorded EMG during muscle contraction and were compared to commercial Ag/AgCl electrodes that use hydrogel. Thirdly, the printed electrodes have been shown to be stable to ten washes with detergent and ten dry cycles upon treatment with commercially sold fabric protectors with ECG signals being recorded in underwater conditions from wrist. Lastly, EDA was measured from fingers by recording changes in skin conductance brought about by cognitive stress. This use of integrated sensors on a t-shirt provides a tool for continuous and simultaneous measurement of vital signals in at-risk patients. © 2020 IOP Publishing Ltd

Mitochondria-targeting drug conjugates for cytotoxic, anti-oxidizing and sensing purposes:current strategies and future perspectives

mitochondrial-targeting moieties to anticancer drugs, antioxidants and sensor molecules. Among them, the most widely applied mitochondrial targeting moiety is triphenylphosphonium(TPP), which is a delocalized cationic lipid that readily accumulates and penetrates through the mitochondrial membrane due to the highly negative mitochondrial membrane potential. Other moieties, including short peptides,dequalinium, guanidine, rhodamine, and F16, are also known to be promising mitochondrial targeting agents. Direct conjugation of mitochondrial targeting moieties to anticancer drugs, antioxidants and sensors results in increased cytotoxicity, anti-oxidizing activity and sensing activity, respectively,compared with their non-targeting counterparts, especially in drug-resistant cells. Although many mitochondria-targeted anticancer drug conjugates have been investigated in vitro and in vivo, further clinical studies are still needed. On the other hand, several mitochondria-targeting antioxidants have been analyzed in clinical phases I, II and III trials, and one conjugate has been approved for treating eye disease in Russia. There are numerous ongoing studies of mitochondria-targeted sensors.

Synthetic hydrogels are widely used as biomimetic in vitro model systems to understand how cells respond to complex microenvironments. The mechanical properties of hydrogels are deterministic for many cellular behaviors, including cell migration, spreading, and differentiation. However, it remains a major challenge to engineer hydrogels that recapture the dynamic mechanical properties of native extracellular matrices. Here, we provide a new hydrogel platform with spatiotemporally tunable mechanical properties to assay and define cellular behaviors under light. The change in the mechanical properties of the hydrogel is effected by a photo-induced switch of the cross-linker fluorescent protein, Dronpa145N, between the tetrameric and monomeric states, which causes minimal changes to the chemical properties of the hydrogel. The mechanical properties can be rapidly and reversibly tuned for multiple cycles using visible light, as confirmed by rheological measurements and atomic force microscopy- based nano-indentation. We further demonstrated real-time and reversible modulation of cell migration behaviors on the hydrogels through photo-induced stiffness switching, with minimal invasion to the cultured cells. Hydrogels with a programmable mechanical history and a spatially defined mechanical hierarchy might serve as an ideal model system to better understand complex cellular functions.
