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...
Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using...
Multifunction superhydrophobic coatings that facilitate water harvesting are attractive for addressing the daunting water crisis, yet, they are caught in a double bind when their durability is considered, as durable coatings will require both tough micro‐textures to survive concentrated stress and high‐surface‐energy chemistry to form chemical bonds within the matrix. To date, a universal bulk‐phase...
Photodynamic therapy (PDT), as a means of locally and rapidly inducing adipocyte death via light illumination, in combination with adipose browning induction, a more gradual and widespread effect that could transform white adipose tissue into thermogenic adipose tissue, manifests a promising approach to combat obesity. Herein, adipose‐targeting ultra‐small hybrid nanoparticles (Pep‐PPIX‐Baic NPs)...
2D multilayered organic‐inorganic hybrid perovskites (OIHPs) have exhibited bright prospects for high‐performance self‐driven X‐ray detection due to their strong radiation absorption and long carrier transport. However, as an effective tool for self‐driven X‐ray detection, radiation photovoltaics remain rare, and underdeveloped in multilayered OIHPs. Herein, chirality to induce radiation photovoltaics...
Neuropeptide Y (NPY), as one of the most abundant neuropeptides known, is widely distributed in the central and peripheral nervous system. However, most of the reported NPY‐mimetic peptides are hard to cross the blood–brain barrier, target glioma mitochondria, and achieve self‐assembly nanostructure in situ. Here, based on the α‐helix structure of the novel chiral NPY‐mimetic peptides D/LNPY(14),...
Superhydrophobic Coatings
In article number 2307561, Youfa Zhang and co‐workers develop a binary cooperative cell design that eliminates the mutual exclusion between the features of functions and mechanical stability of superhydrophobic coatings. The coating is structurally strong and exhibits almost all aspects of enhancement including ultra‐durability and over 1000% enhancement in water harvesting...
Rechargeable aqueous zinc‐ion batteries are practically plagued by the short lifespan and low Coulombic efficiency (CE) of Zn anodes resulting from random dendrite deposition and parasitic reactions. Herein, the host−guest chemistry of cucurbituril additive with Zn2+ to achieve longstanding Zn anodes is manipulated. The macrocyclic molecule of cucurbit[5]uril (CB[5]) is delicately designed to reconstruct...
Understanding the gold core‐ligand interaction in gold nanoclusters (GNCs) is essential for the on‐demand tailoring of their photoluminescence properties and long‐term stability. Here, inspired by the suckers arranged directionally on the tentacles of octopus, a series of GNCs with regulating ligand structures are grown and stabilized on the cellulose nanocrystals (CNCs). The carboxylated CNCs providing...
Lymph node metastasis (LNM) is a significant barrier to the prognosis of patients with gastric cancer (GC). Helicobacter pylori (H. pylori)‐positive GC patients experience a higher rate of LNM than H. pylori‐negative GC patients. However, the underlying mechanism remains unclear. Based on the findings of this study, H. pylori‐positive GC patients have greater lymphangiogenesis and lymph node immunosuppression...
The family of metal‐free molecular perovskites, an emerging novel class of eco‐friendly semiconductor, welcomes a new member with a unique 1D hexagonal perovskite structure. Lowering dimensionality at molecular level is a facile strategy for crystal structure conversion, optoelectronic property regulation, and device performance optimization.

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...
During the layer‐by‐layer (LBL) processing of polymer solar cells (PSCs), the swelling and molecule interdiffusion are essential for achieving precise, controllable vertical morphology, and thus efficient PSCs. However, the influencing mechanism of material properties on morphology and correlated device performance has not been paid much attention. Herein, a series of fluorinated/non‐fluorinated polymer...

Inspired by the unique structure of octopus suckers arranged directionally on its tentacles, a series of gold nanoclusters (GNCs) grown in situ along cellulose nanocrystals are synthesized. The fluorescence properties and oxidative properties of GNCs are investigated, and a generalized strategy for constructing DCGRFP is provided. More In article number 2307770, Hongxiang Zhu, Hui...
Self‐trapped excitons (STEs) typically give broadband photoluminescence emission with a large Stokes shift, which is important for the enhancement of the optical properties of materials. Here, low‐dimensional La‐doped BaTiO3 nanocrystals with defects are prepared using supercritical CO2 (SC CO2). The generation of the STEs is facilitated by doping La3+ ions and introducing CO2 pressure, which effectively...

Targeting the representative oncogenic miR‐21, the as‐functionalized nanopipette permits direct intracellular drug administration with precisely controllable dosages,...
Structural damage of Ni‐rich layered oxide cathodes such as LiNi0.8Co0.1Mn0.1O2 (NCM811) and serious interfacial side reactions and physical contact failures with sulfide electrolytes (SEs) are the main obstacles restricting ≥4.6 V high‐voltage cyclability of all‐solid‐state lithium batteries (ASSLBs). To tackle this constraint, here, a modified NCM811 with Li3PO4 coating and B/P co‐doping using inexpensive...
The construction of stable copper nanoclusters (Cu‐NCs) with near‐infrared (NIR) emission that can be used for catalysis is highly desired, yet remains a challenge.

Single‐crystal X‐ray crystallographic analysis...
2D transition metal dichalcogenides (TMDs) have garnered significant interest as cathode materials for aqueous zinc‐ion batteries (AZIBs) due to their open transport channels and abundant Zn2+ intercalation sites. However, unmodified TMDs exhibit low electrochemical activity and poor kinetics owing to the high binding energy and large hydration radius of divalent Zn2+. To overcome these limitations,...
