High‐power‐density electronic devices under vibrations call for soft and damping thermal interface materials (TIMs) for efficient heat dissipation. However, integrating low hardness, high damping, and superior heat transfer capability into one TIM is highly challenging. Herein, soft, damping, and thermally conductive TIMs are designed and prepared by constructing a honeycomb‐board‐mimetic boron nitride...
A visible‐light‐driven CO2 reduction optical fiber is fabricated using graphene‐like nitrogen‐doped composites and hollow quartz optical fibers to achieve enhanced activity, selectivity, and light utilization for CO2 photoreduction. The composites are synthesized from a lead‐based metal–organic framework (TMOF‐10‐NH2) and g‐C3N4 nanosheet (CNNS) via electrostatic self‐assembly. The TMOF‐10‐NH2/g‐C...
Seawater electrolysis holds tremendous promise for the generation of green hydrogen (H2). However, the system of seawater‐to‐H2 faces significant hurdles, primarily due to the corrosive effects of chlorine compounds, which can cause severe anodic deterioration. Here, a nickel phosphide nanosheet array with amorphous NiMoO4 layer on Ni foam (Ni2P@NiMoO4/NF) is reported as a highly efficient and stable...
Excessive ultraviolet (UV) radiation has serious damage to human's health, therefore the development of visible, portable, and wearable sensor for monitoring UV radiation, especially the cumulative UV dosage, is highly desired but full of challenges. Herein, a wearable and flexible UV dosimeter based on photochromic perovskite nanocrystals (PNCs) is designed. The obtained CsPbCl3 PNCs dispersed in...
Bispecific antibodies possess exceptional potential as therapeutic agents due to their capacity to bind to two different antigens simultaneously. However, challenges pertain to unsatisfactory stability, manufacturing complexity, and limited tumor penetration hinder their broad applicability. In this study, a versatile technology is presented for the rapid generation of bispecific nanobody‐aptamer...
Transition metal selenides (TMSs) have great potential as cathode materials for alkaline Zn batteries (AZBs) owing to their high theoretical capacity and metallic conductivity. However, achieving a high specific capacity remains a formidable challenge due to the low structural stability and sluggish reaction kinetics of single‐phase TMS. Herein, a facile method for fabricating a robust CoSe2@Ni3Se...
Due to its tumor homing and long serum half‐life, albumin is an ideal drug carrier for chemotherapy. For endogenous albumin hitchhiking with high cargo loading, a trimeric albumin‐binding domain (ABD), i.e., ABD‐Tri is designed by fusing an ABD with high specificity and affinity for albumin to a self‐trimerizing domain (Tri) with an additional cysteine residue. ABD‐Tri is highly (40 mg L−1) expressed...
High‐efficiency adsorption of aromatic sulfur‐containing compounds from liquid hydrocarbon fuels over metal‐organic frameworks (MOFs) is challenging because of inert metal sites. A new method, the Ce‐enhanced modulation of MOFs’ microenvironment, is proposed to modulate the –COO···Cu(II)– coordination microenvironment of Hong Kong University of Science and Technology (HKUST‐1) using Ce(III) as a molecular...
Nanoparticle surfactants (NPSs) offer a powerful means to stabilize the oil‐water interface and construct all‐liquid devices with advanced functions. However, as the nanoparticle size decreases to molecular‐scale, the binding energy of the NPS to the interface reduces significantly, leading to a dynamic adsorption of NPS and “liquid‐like” state of the interfacial assemblies. Here, by using the host‐guest...
Metal–organic frameworks (MOFs), known as porous coordination polymers, have attracted intense interest as electrode materials for supercapacitors (SCs) owing to their advantageous features including high surface area, tunable porous structure, structural diversity, etc. However, the insulating nature of most MOFs has impeded their further electrochemical applications. A common solution for this issue...
In this work, a LaB6‐alloying strategy is reported to effectively boost the figure‐of‐merit (ZT) of Ge0.92Bi0.08Te‐based alloys up to ≈2.2 at 723 K, attributed to a synergy of La‐dopant induced band structuring and structural manipulation. Density‐function‐theory calculations reveal that La dopant enlarges the bandgap and converges the energy offset between the sub‐valence bands in cubic‐structured...
