The effect of accelerated weathering on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and PHBV-based nanocomposites with rutile titanium (IV) dioxide (PHBV/TiO2) was investigated. The accelerated weathering test applied consecutive steps of UV irradiation (at 340 nm and 0.76 W m−2 irradiance) and moisture at 50…
Moir\'e patterns are known to confine electronic states in transition metal dichalcogenide bilayers, thus generalizing the notion of magic angles discovered in twisted bilayer graphene to semiconductors. Here, we present a revised Slater-Koster tight-binding model that facilitates reliable and systematic studies of su…
Recently, combinations of 2D van der Waals (2D vdW) materials and organic materials have attracted attention because they facilitate the formation of various heterojunctions with excellent interface quality owing to the absence of dangling bonds on their surface. In this work, a double negative differential resistance…
We report a new type of highly efficient visible light-driven photocatalyst, Sm 3+ -activated BiOF nanoparticles, developed by a facile solid-state reaction technology. The corresponding phase compositions, morphological nature, and chemical states along with complementary theoretical calculation insights are investig…
Realizing robust DNA functionalization with strict valence control in the sub-2-nm thiolate-protected luminescent gold nanoparticles (AuNPs) is highly demanded but remains unsolved due to their unique Au(0) core and Au(I)–S shell structures. Herein, we report a facile strategy using phosphorothioates (ps)-modified DNA…
This work is mainly focused on developing a self-heating composite fabric using the PVF and PPP. Prepare a new functional composite self-heating fabric through core spun method based on the synergy of hygroscopic heating principle and the characteristics of piezoelectricity of tourmaline. PVF with good hygroscopicity…
Thermoelectric technology, which is characterized by the interconversion between heat and electricity, is demonstrated as an efficient and environmentally friendly route for thermal energy harvesting and solid-state cooling devices. The pursuit for high-performance room temperature thermoelectric materials is of signi…
Abstract Two-dimensional transition metal dichalcogenides (2D TMDs), such as WS 2 , are considered to have the potential for high-performance gas sensors. It is a pity that the interaction between gases and pristine 2D WS 2 as the sensitive element is too weak so that the sensor response is difficult to detect. Herein…
In order to interpret the mechanical response of thin films subjected to scratch tests, it is necessary to elucidate local stress distributions and microstructural changes accompanying deformation across the scratch track area. Here, 50 nm synchrotron cross-sectional X-ray nanodiffraction and electron microscopy are u…
In this study, a flexible polymer (polysiloxane) containing SiOSi molecular chains and epoxy groups (EPSE) was prepared. The effect of EPSE on the cryogenic mechanical properties of epoxy matrix and carbon fiber (CF) reinforced epoxy composite laminate was investigated in detail. At RT, with an EPSE content of 8 wt%,…
High performance magnetocaloric materials are crucial to realize the energy efficient and environment friendly magnetic cooling/refrigeration technology. We have designed Mn 1-x Cu x CoGe compounds possessing a giant magnetocaloric effect near room temperature. The magnetic and structural degree of freedom have been c…
Abstract Herein we report on the catalytic activity of Ti‐based MXenes (Ti3CNTz and Ti3C2Tz) for biomass transformation. MXenes were found to be active catalysts for the hydrogenation of furfural using either gaseous hydrogen or 2‐propanol as solvent and hydrogen source. Both catalysts showed good activity in the conv…
Abstract Transparent conducting oxides are fundamental for the fabrication of optoelectronic devices including touchscreen displays, solar cells, and light emitting diodes. However, they mostly rely on rare elements and expensive vacuum‐based deposition methods that negatively affect the overall cost of optoelectronic…
ZnO particles were synthetized by the sol-gel method and subsequent heat treatment of 400, 500 and 600 °C was applied. The nano ZnO particles were incorporated to the unsaturated polyester resin by solution blending at 0.05 wt % concentration. X-ray diffraction detected the formation of a wurtzite-like structure. Visc…
Collagen, the most abundant protein in mammals, possesses notable cohesion and elasticity properties and efficiently induces tissue regeneration. The Gly-Pro-Hyp canonical tripeptide repeating unit of the collagen superhelix has been well-characterized. However, to date, the shortest tripeptide repeat demonstrated to…
Abstract The helical phase structure of a twisted light beam has attracted big interest in both fundamental science and practical applications. A facile metasurface approach to generate and manipulate ring vortex beams is reported and experimentally demonstrated. The generation of ring vortex beams is realized by comb…
Abstract 2D bismuth oxyselenide (Bi 2 O 2 Se) with high electron mobility is advantageous in future high‐performance and flexible electronic and optoelectronic devices. However, transfer of thin Bi 2 O 2 Se flakes is rather challenging, restricting measurements of its mechanical properties and application exploration…
In this study, magnetic nanoparticles composed of a core (doxorubicin–gelatin) and a shell layer (Fe3O4–alginate) were developed to function as targeted anticancer drug delivery vehicles. The anticancer drug doxorubicin (DOX) was selected as a model drug and embedded in the inner gelatin core to obtain high encapsulat…
