Abstract To date, organic–inorganic hybrid perovskite solar cells (PSCs) have reached a certified efficiency of 25.7%, showing great potential in upscale industrial commercialization. However, huge obstacle facing the industrialization PSCs is decreased and long‐term stability when upscaling device area. overcome these issues, blade‐coating methods been developed to fabricate large‐area due their capability deposit uniform films. Ink engineering plays an important role blade‐coating,...
The lack of both digital light processing (DLP) compatible and biocompatible photopolymers, along with inappropriate material properties required for wearable sensor applications, substantially hinders the employment DLP 3D printing in fabrication multifunctional hydrogels. Herein, we discovered implemented a photoreactive poloxamer derivative, Pluronic F-127 diacrylate, which overcomes these limitations is optimized to achieve printed micelle-based hydrogels high structural complexity,...
Abstract Exploring the abundant resources in ocean requires underwater acoustic detectors with a high-sensitivity reception of low-frequency sound from greater distances and zero reflections. Here we address both challenges by integrating an easily deformable network metal nanoparticles hydrogel matrix for use as cavity-free microphone. Since can be densely implanted inclusions, even arranged coherent arrays, this microphone detect static loads air breezes different angles, well signals 20...
Hydrogels as soft and wet materials have attracted much attention in sensing flexible electronics. However, traditional hydrogels are fragile or unsatisfactory recovery capability, which largely limit their applications. Here, a novel hydrogen bond based sulfuric acid-poly(acrylic acid) (PAA)/poly(vinyl alcohol) physical hydrogel is developed for addressing the above drawbacks. Sulfuric acid serves two functions: one to inhibit ionization of carboxyl groups from PAA chains form more bonds...
Abstract With the rapid iteration of portable electronics and electric vehicles, developing high-capacity batteries with ultra-fast charging capability has become a holy grail.

Phase boundaries active anode believed...
The construction of "smart" materials able to perform specific functions at the molecular scale through application various stimuli is highly attractive but still challenging. most recent applications indicate that outstanding flexibility self-assembled architectures can be employed as a powerful tool for development innovative devices, functional surfaces and smart nanomaterials. Structural these known conferred by weak intermolecular forces involved in self-assembly strategies. However,...
Abstract Caffeine is a major component of xanthine alkaloids and commonly consumed in many popular beverages. Due to its occasional side effects, reduction caffeine natural way great importance economic significance. Recent studies reveal that can be converted into non-stimulatory theacrine the rare tea plant Camellia assamica var. kucha (Kucha), which involves oxidation at C 8 methylation N 9 positions caffeine. However, underlying molecular mechanism remains unclear. Here, we identify...
Trendy advances in electric cars and wearable electronics triggered growing awareness device lethality/survivability from accidents. A divergent design protection calls for high stress resistance, large ductility, as well efficient energy dissipation, all the itself, while keeping weight-specific performance to its premium. Unfortunately, polymer electrolyte or ductile elastomer lacks a mechanistic resist puncture tear at level. Here, we designed molecular complexes along phase boundaries...
Solvent and reagent filters were micromachined into quartz wafers using deep reactive ion etching to create a network of intersecting 1.5 x 10 microns channels. When placed at the bottom reservoirs with side exit, this channel behaved as lateral percolation filter composed an array cubelike structures one layer deep. Flow through these was driven by electroosmotic flow (EOF). Silanol groups walls channels in provided requisite charge trigger EOF when voltage applied laterally filter....
To investigate the effects of oxygen staging and excess on combustion performance gaseous pollutant emission, oxy-fuel experiments with Datong coal were carried out in a 0.1 MWth circulating fluidized-bed (CFBC) apparatus under an O2/CO2 atmosphere total O2 concentration 50%. The resulting CO2 was higher than 90% flue gas most experimental conditions. In combustion, oxygen-staging is new, effective, safe method for improving performance, although flow-staging remains effective. CO initially...

A perfect impedance match from water-rich hydrogels to an oceanic background makes hydrogel microphones ideal for long-distance, underwater acoustic reception with zero reflection. novel hydrogel-graphene transistor is thus designed work under a gate-free mode, in which sheet of graphene directly converts mechanical vibrations microstructured into electrical current. This shows that the quantum capacitance plays important role determining shift Fermi level and subsequently amplitude current...
