Generating sustainable electricity from ambient humidity and natural evaporation has attracted tremendous interest recently as it requires no extra mechanical energy input is deployable across all weather geography conditions. Here, we present a device prototype for enhanced power generation humidity. This uses both heterogenous materials assembled LiCl-loaded cellulon paper to facilitate moisture adsorption carbon-black-loaded promote water evaporation. Exposing such centimeter-sized can...
Broadening semi-wet gas–liquid–solid three phase regions in a nanoporous film boosts water-evaporation-induced electricity and produces an integrated one kilovolt output.
Hydrovoltaic technology has achieved notable breakthroughs in electric output via using the moving boundary of double layer, but voltage induced by droplets is saturated around 350 volts, and underlying mechanism remains to be further clarified. Here, we show that falling water can stably spark an unprecedented up 1200 volts within microseconds they contact electrode placed on top electret surface, approaching theoretical upper limit. This sparking potential explained described a...
Abstract Water, the source of life, contains immense energy and manifests in diverse forms. Hydrovoltaic technology enables direct interaction between water materials to generate electricity, a vital necessity for industry modernization. Due ubiquitous presence easy availability falling water, hydrovoltaic derived from droplets has attracted considerable attention shown great potential raindrop harvesting. In this review, comprehensive summary latest advancements harvesting is presented,...
Water-evaporation-induced (WEI) electricity generation has been widely studied, but the explanation for working mechanism remains controversial yet. In this study, porous carbon black (CB) films with multiple parallel electrodes were prepared and voltage distribution in these was investigated during WEI generation. We found that both toluene ethanol CB films, between neighboring increases first then decreases increasing height above bulk water surface. This derives from similar volumetric...
Soft films serve as the primary support materials for flexible devices. These are frequently peeled perpendicularly during device preparation and application, resulting in large compression on upper surface of bending region significant damage to device's performance. Accurately assessing this is challenging because difficulties calculating large-deformation films. In study, we propose a method calculate compressive strain soft film using only its thickness key parameter. Furthermore,...
Flexible intelligent materials are desired to effectively regulate their own deformation and accurately sense immediate morphology at the same time. Graphene foam is an attractive material for strain sensing electrical/thermal performance control due its outstanding mechanical, electrical, thermal properties. However, graphene-foam-based with both capabilities rarely reported. Here, a multiscale design of graphene single-layer-graphene-dominated microstructure resilient 3D network...
In the carotenoid biosynthesis pathway, phytoene synthase (PSY) catalyzes dimerization of two molecules geranylgeranyl pyrophosphate (GGPP) to and has been shown be a rate-limiting enzyme for synthesis carotenoids. this study, PCR approach was used isolate cDNA from flower Osmanthus fragrans. It contained 1314 bp CDS. The predicted protein (49.4 kDa) displayed sequence 438 amino acid residues. Phylogenetic analysis demonstrated that O. fragrans PSY gene (OfPSY) clustered with Gardenia...
Abstract Recent experiments have demonstrated an extremely high output voltage of 260 V by impinging droplets on electret surface with top and back electrodes. However, the mechanism underlying generated remains elusive. Through high‐speed imaging water droplet, it is found that recorded proportional to change rate contact length l between droplet electrode over time, is, d /d t . By combining electrostatic model multi‐physics simulations, time‐dependent charge distribution analytically...
Ni-doped anatase TiO2 nanobelts (NBs) with different Ni2+ contents were simply prepared by combining ion-exchange hydrothermal treatment. They characterized X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), high-resolution (HRTEM), photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), and magnetic measurement techniques. The results showed that cations doped into the lattice no metallic nickel clusters or nanoparticles could be found....
A strategy involving free radical copolymerization of a difunctional oligomer and small-molecule crosslinker to give sub-10 nm nanogels is proposed. These can adapt surrounding temperatures regulate the release preloaded model anticancer drug 5-fluorouracil.
A rarely seen butterfly species, the large swallowtail Papilio elwesi Leech, 1889 (Lepidoptera: Papilionidae), endemic to Chinese mainland, has been declared a state-protected animal in China since 2000, but its genome is not yet available. To obtain high-quality assembly and annotation, we sequenced transcriptome of P. using PacBio PromethION platforms, respectively. The final assembled was 358.51 Mb, which 97.59% anchored chromosomes (30 autosomes 1 Z sex chromosome), with contig/scaffold...
Fracture control in membranes is highly desirable nano-technology, but a great challenge because of the 'multi-scale' complexity fracture initiation and propagation. Here, we devise method that can controllably direct fractures stiff nanomembranes, realized by 90° peeling nanomembrane overlaid on soft film, i.e., stiff/soft bilayer, from substrate underneath. The allows membrane to be creased into film periodically bending region fractured along unique bottom line crease, i.e, route strictly...
Abstract The buckling behavior of stiff/soft bilayer films has been extensively studied over the past three decades. However, strategies to characterize structures on complex surfaces caused by film deformation, such as bending and spherical bilayers, are still lacking, preventing an accurate understanding behaviors in a broader context. Here, frozen effect is reported which provides solution aforementioned problem. patterns can be electron‐beam irradiation, attributed irradiation‐induced...
The buckling behavior of graphene on soft films has been extensively studied. However, to avoid fracture, most studies focus only the primary induced by tiny compression. Here, monolayer, three-layer, and four-layer is systematically studied in experiment under large cross-sections patterns these few-layer graphenes are provided, which depend focused ion beam (FIB) technology. More significantly, moduli calculated based behavior. We demonstrate that modulus, 1.12621 TPa, independent number...
