Post-traumatic massive hemorrhage demands immediately available first-aid supplies with reduced operation time and good surgical compliance. In-situ crosslinking gels that are flexibly adapting to the wound shape have a promising potential, but it is still hard achieve fast gelation, on-demand adhesion, wide feasibility at same time.A white-light crosslinkable natural milk-derived casein hydrogel bioadhesive presented for first time. Benefiting from abundant tyrosine residues, was...
The flexible nature and high surface-to-volume ratio make monolayer-MoS2 a novel paradigm for tunable nanoelectronic devices. However, further improvement in the performance of these devices, new design strategy is essential to modulate properties an inert MoS2 basal plane. Here, we demonstrate from first-principles that gas adsorption magnetic can be modulated through MoS antisite doping strain. defect with localized d-orbital electron density significantly promotes catalytic activity which...

It demonstrated that some dependent temperature.
To achieve a fundamental understanding of the multiferroic behavior and electronic properties intrinsic vacancies in $\mathrm{BiFe}{\mathrm{O}}_{3}$, here we performed first-principles calculations based on hybrid Hartree-Fock density functional theories, which can accurately describe defect structures. Oxygen vacancies, behave as deep donors with high concentrations under oxygen-poor conditions, reduce magnetic moments at neighboring Fe ions neutral state, while charged oxygen induce...
Chalcogenide perovskites with optimal band gap and desirable light absorption are promising for photovoltaic devices, whereas the absence of ferroelectricity limits their potential in applications. On basis first-principles calculations, we reveal underlying mechanism paraelectric nature Ba3Zr2S7 observed experiments demonstrate a general rule appearance chalcogenide Ruddlesden-Popper (RP) A3B2X7 structures. Group theoretical analysis shows that tolerance factor is primary dominates...
The electrocaloric properties of multi-domain ferroelectrics are investigated using a phase field model. simulation results show that the extrinsic contribution from to mono-domain transition driven by temperature significantly enhances response. Due abrupt decrease polarization in direction electric during domain transition, large adiabatic change is achieved for subjected tensile strain. Furthermore, can be tuned external strains as temperature. A compressive strain decreases while...
Hydrophobic ceramics with low surface energies have a broad range of applications in both industry and domestic fields. However, the common surface-treatment-based hydrophobic are usually vulnerable easily lose functions due to surficial mechanical damages. To address this challenge, here we propose new strategy produce intrinsically by leveraging alkylated-geopolymerization. As proof-of-concept, designed synthesized an alkylated-geopolymer (AGP) based ceramic excellent waterproof...
