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...

3D ZIF‐67‐particles‐impregnated cellulose‐nanofiber nanosheets with oriented macropores are synthesized via directional‐freezing‐assisted in situ self‐assembly, and converted to 3D CoP‐nanoparticle (NP)‐embedded hierarchical, but macropores‐oriented, N‐doped carbon nanosheets via calcination and phosphidation. The obtained nanoarchitecture delivers overpotentials at 10 and 50 mA cm−2 and Tafel slope...
Thermal management is of vital importance in various modern technologies such as portable electronics, photovoltaics, and thermoelectric devices.

Herein, a significant reduction of lattice thermal conductivity (κL) is achieved by applying...
Carbon‐based nanomaterials have been widely utilized in catalysis and energy‐related fields due to their fascinating properties. However, the controllable synthesis of porous carbon with refined morphology is still a formidable challenge due to inevitable aggregation/fusion of resulted carbon particles during the high‐temperature synthetic process. Herein, a hierarchically oriented carbon‐structured...
Hypoxia severely impedes photodynamic therapy (PDT) efficiency. Worse still, considerable tumor metastasis will occur after PDT.

Due to substantial phonon scattering induced by various structural defects, the in‐plane thermal conductivity (K) of graphene films (GFs) is still inferior to the commercial pyrolytic graphite sheet (PGS).
