Acidic residues (Asp and Glu) have a high prevalence on protein surfaces, but cross‐linking reactions targeting these residues are limited. Existing methods either require high‐concentration coupling reagents or have low structural compatibility. Here a previously reported “plant‐and‐cast” strategy is extended to develop heterobifunctional cross‐linkers. These cross‐linkers first react rapidly with...
As the electron transport layer in quantum dot light‐emitting diodes (QLEDs), ZnO suffers from excessive electrons that lead to luminescence quenching of the quantum dots (QDs) and charge‐imbalance in QLEDs. Therefore, the interplay between ZnO and QDs requires an in‐depth understanding. In this study, DFT and COSMOSL simulations are employed to investigate the effect of sulfur atoms on ZnO. Based...
Quantum Dot Light‐Emitting Diodes
In article number 2307298, Xiao Wei Sun and co‐workers improved quantum dot light‐emitting diodes (QLEDs) by thiol ligands of ZnO. ZnO nanocrystals were modified to reduce electron excess without hindering charge injection. This modification strategy significantly enhanced QLED performance, achieving an external quantum efficiency of over 23% and a long lifetime of...
Materials with various single‐transition metal atoms dispersed in nitrogenated carbons (M─N─C, M = Fe, Co, and Ni) are synthesized as cathodes to investigate the electrocatalytic behaviors focusing on their enhancement mechanism for performance of Li–S batteries. Results indicate that the order of both electrocatalytic activity and rate capacity for the M─N─C catalysts is Co > Ni > Fe, and the...
Structural and compositional design of multifunctional materials is critical for electrocatalysis, but their rational modulation and effective synthesis remain a challenge. Herein, a controllable one‐pot synthesis for construction of trifunctional sites and preparation of porous structures is adopted for synthesizing dispersed MoCoP sites on N, P codoped carbonized substance. This tunable synthetic...
Fe‐doped Ni (oxy)hydroxide shows intriguing activity toward oxygen evolution reaction (OER) in alkaline solution, yet it remains challenging to further boost its performance. In this work, a ferric/molybdate (Fe3+/MoO42−) co‐doping strategy is reported to promote the OER activity of Ni oxyhydroxide. The reinforced Fe/Mo‐doped Ni oxyhydroxide catalyst supported by nickel foam (p‐NiFeMo/NF) is synthesized...
Microgels are soft microparticles that often exhibit thermoresponsiveness and feature a transformation at a critical temperature, referred to as the volume phase transition temperature. Whether this transformation occurs as a smooth or as a discontinuous one is still a matter of debate. This question can be addressed by studying individual microgels trapped in optical tweezers. For this aim, composite...
Electrochemical CO2‐to‐CO conversion offers an attractive and efficient route to recycle CO2 greenhouse gas. Molecular catalysts, like CoPc, are proved to be possible replacement for precious metal‐based catalysts. These molecules, a combination of metal center and organic ligand molecule, may evolve into single atom structure for enhanced performance; besides, the manipulation of molecules’ behavior...
Cancer Immunotherapy
In article number 2201298, Houjie Liang, Songtao Yu, and co‐workers report how localized cancer phototherapy on primary tumors with nanosized small molecule‐albumin complexes by in vivo self‐assembly, ultimately trigger sufficient antitumor immune responses to effectively suppress growths of distant metastatic tumors.
Cancer immunotherapy has great potential in tumor eradication and metastasis suppression. However, systemic administration of immune adjuvants and inadequate specificity in cancer treatment, lead to restricted therapeutic benefits and potential immune‐related side effects in clinical settings. In this report, the synthesis of various lengths of heptamethine cyanine small molecules to act as multifunctional...
Electrophoretic deposition (EPD) is a facile technique to deposit quantum dots (QDs) films, which can be used as the color conversion layers for display applications. To better understand the EPD process, researchers have built many models of the EPD process. However, most of these models lack solid experimental support. Here, by adopting simple yet effective solvent engineering and well‐designed...
Metal sulfides, as vital members of electrodes materials, still suffer from serious volume expansion and polysulfides shuttling. Herein, through inexpensive and high efficiency chemical‐bonding/hydrophobic‐association methods, a series of metal‐sulfides quantum dots (QDs) with large‐scale synthesis (≈100 g) is successfully prepared, further forming low‐dimensional composites with high redox activity...
Rechargeable alkaline Zn–air batteries (ZABs) are attracting extensive attention owing to their high energy density and environmental friendliness. However, the dilemma of Zn anode, composed of ineluctable passivation and dissolution problems, severely hinders the discharge and cycling performance of the battery. Herein, the authors propose a chemical buffer layer coated on Zn metal (CBL@Zn) anode,...
Antimony sulfide is attracting enormous attention due to its remarkable theoretical capacity as anode for sodium‐ion batteries (SIBs). However, it still suffers from poor structural stability and sluggish reaction kinetics. Constructing covalent chemical linkage to anchor antimony sulfide on two‐dimension conductive materials is an effective strategy to conquer the challenges. Herein, Ti3C2‐Sb2S3 composites...
Transformation of CO2 into value‐added products via photothermal catalysis has become an increasingly popular route to help ameliorate the energy and environmental crisis derived from the continuing use of fossil fuels, as it can integrate light into well‐established thermocatalysis processes. The question however remains whether negative CO2 emission could be achieved through photothermal catalytic...
While organic–inorganic halide perovskite solar cells (PSCs) show great potential for realizing low‐cost and easily fabricated photovoltaics, the unexpected defects and long‐term stability against moisture are the main issues hindering their practical applications.

A new hole transporting material (HTM) named DMZ is synthesized and employed as a dopant‐free HTM in inverted planar perovskite solar cells (PSCs). Systematic studies demonstrate that the thickness of the hole transporting layer can effectively enhance the morphology and crystallinity of the perovskite layer, leading to low series resistance and less defects in the crystal. As a result, the champion...
Photothermal therapy (PTT) usually requires hyperthermia >50 °C for effective tumor ablation, which inevitably induces heating damage to the surrounding normal tissues/organs. Moreover, low tumor retention and high liver accumulation are the two main obstacles that significantly limit the efficacy and safety of many nanomedicines. To solve these problems, a smart albumin‐based tumor microenvironment‐responsive...
