Recent experiments have demonstrated that moving water droplets on polymer-supported graphene can generate electric voltages in graphene. Here, we perform a multi-scale analysis on the mechanism of the generated voltages on the basis of an interplay among the substrate, graphene and ionic water. We find that the attraction of ions in water by substrate dipoles drives charge redistribution in graphene, forming an electric triple layer (ETL) at the water/graphene/substrate interface, made of an io...

Although a great deal of studies focus on the design of flexible energy storage devices (ESDs), their mechanical behaviors under bending states are still not sufficiently investigated, and the understanding of the corresponding structural conversion therefore still lags behind. Here, we systematically and thoroughly investigated the mechanical behaviors of flexible all-in-one ESDs under bending deformation by the finite element method. The influences of thicknesses, Young’s moduli and Poisson’s ...

Magnesium (Mg) and its alloys are considered as ideal biodegradable materials due to their excellent mechanical properties and biocompatibility. In order to improve the surface properties to allow better adaptation to the surrounding tissue of the body, surface modification has played a significant role in satisfying multiple clinical requirements such as corrosion resistance, biocompatibility, and antibacterial ability. Here, layer-by-layer (LbL) self-assembly, which can be applied for biodegra...

The mechanical properties of nanoporous metals (NPMs) are very important for their potential applications in flexible electronics. Here, the NP Cu@Zr-Cu-Al metallic glass (NP Cu@Zr-Cu-Al MG) composite with high strength, high hardness, and good flexibility is reported. The NP Cu@Zr-Cu-Al MG was synthesized by a two-step dealloying method. First, the flexible NP Zr-Cu-Al MG was prepared by selective etching the active Y-rich MG from the pseudobinary MG system (Zr47Cu46Al7 MG + Y47Cu46Al7 MG) of C...

Oxygen vacancy-rich bismuth oxysulfide (Bi2O2S) with layered structure was prepared for efficient photocatalytic CO2 reduction under visible light irradiation. The existence of rich oxygen vacancies in Bi2O2S, which was proven by sufficient characterization, can provide abundant active sites, improve CO2 adsorption and activation abilities and boost the separation efficiency of photogenerated carriers, as determined by theoretical and experimental analyses. As a result, Bi2O2S with rich oxygen v...

The response speed of the reported Cs2AgBiBr6-based photodetectors exhibits a wide variation ranging from microseconds to nanoseconds, while the reason is still unclear. Apart from the conventional approaches such as reducing effective area, new regulating approaches for response speed improvement have rarely been reported. On the other hand, it is generally believed that ultraviolet (UV) light has negative impact on perovskite devices resulting in performance degradation. In this work, we demon...

Rational composite design is highly important for the development of high-performance composite polymer electrolytes (CPEs) for solid-state lithium (Li) metal batteries. In this work, Li closo-borohydride, Li2B12H12, is introduced to poly(vinylidene fluoride)-Li-bis-(trifluoromethanesulfonyl) imide (PVDF-LiTFSI) with a bound N-methyl pyrrolidone plasticizer to form a novel CPE. This CPE shows superb Li+ conduction properties, as evidenced by its conductivity of 1.43 × 10−4 S cm−1 and Li+ transfe...

Bacterial infections are grave threats to human health, particularly those caused by the most common Gram-positive bacteria. The massive administration of broad-spectrum antibiotics to treat various bacterial infections has led to the evolution and spread of drug resistance. As a universal antimicrobial technique unapt to induce drug resistance, photothermal therapy (PTT) is attracting extensive attention in recent years. However, its unspecific killing capability and side effects towards adjace...

As a sister compound of MnBi2Te4, the high-quality MnSb2Te4 single crystals are grown via solid-state reaction where prolonged annealing and narrow temperature window play critical roles on account of its thermal metastability. Single-crystal X-ray diffraction (SCXRD) analysis on MnSb2Te4 illustrates a crystal model that is isostructural to MnBi2Te4, consisting of Te-Sb-Te-Mn-Te-Sb-Te septuple layers (SLs) stacking in an ABC sequence. However, MnSb2Te4 reveals a more pronounced cation intermixin...

Heterogeneous molecular catalysts, such as metal phthalocyanines, are efficient electrocatalysts for CO2 reduction reaction (CO2RR). However, the rational design and synthesis of a molecular catalyst-based heterostructure for CO2RR remains challenging. Herein, we developed a crystalline bimetallic phthalocyanine heterostructure electrocatalyst (CoPc/FePc HS), which achieved an excellent CO2-to-CO conversion efficiency (99%) and outstanding long-term stability after 10 h of electrocatalysis. Dens...
