The guided‐growth strategy has been widely explored and proved its efficacy in fabricating surface micro/nanostructures in a variety of systems. However, soft materials like polymers are much less investigated partly due to the lack of strong internal driving mechanisms. Herein, the possibility of utilizing liquid crystal (LC) ordering of smectic liquid crystal polymers (LCPs) to induce guided growth...
Porous frameworks that display dynamic responsiveness are of interest in the fields of smart materials, information technology, etc. In this work, a novel copper‐based dynamic metal‐organic framework [Cu3TTBPE6(H2O)2] (H4TTBPE = 1,1,2,2‐tetrakis(4″‐(1H‐tetrazol‐5‐yl)‐[1,1″‐biphenyl]‐4‐yl)ethane), denoted as HNU‐1, is reported which exhibits modulable photoelectromagnetic properties. Due to the synergetic...
Tin‐lead (Sn‐Pb) mixed perovskites is beneficial to a single‐junction or all‐perovskite tandem device. However, the poor quality of the perovskite surface resulting from Sn2+ oxidation and uncontrollable crystallization degrades device performance and stability. Herein, based on interface engineering, a novel biguanide derivative of PZBGACl is employed that integrates different types of N‐related...
High nickel cathode material LiNixCoyMn1−x−yO2 (NCM) (x ≥ 0.6) has represented the most critical material in virtue of outstanding specific capacity and low self‐discharge. However, the high surface alkalinity and detrimental interfacial stability lead to the parasitic reaction and a series of phase deterioration. Herein, in situ cross‐linking binder molecular chains with a 3D network structure to...
Sodium‐ion batteries (SIBs) have gradually become one of the most promising energy storage techniques in the current era of post‐lithium‐ion batteries. For anodes, transitional metal selenides (TMSe) based materials are welcomed choices , owing to relatively higher specific capacities and enriched redox active sites. Nevertheless, current bottlenecks are blamed for their poor intrinsic electronic...
Designing smart textiles for personal thermal management (PTM) is an effective strategy for thermoregulation and energy saving. However, the manufacture of versatile high‐performance thermal management textiles for complex real‐world environments remains a challenge due to the limitations of functional integration, material properties, and preparation procedures. In this study, an aramid fabric based...
In this study, using PM6:L8‐BO as the main system and non‐fullerene acceptor IDIC as the third component, a series of ternary organic solar cells (TOSCs) are fabricated. The results reveal that IDIC plays a significant role in enhancing the performance of TOSCs by optimizing the morphology of blended films and forming interpenetrating nanostructure. The improved film morphology facilitates exciton...
Until now, poly(3,4‐ethylenedioxythiophene):poly(styrensulfonate) (PEDOT:PSS) is widely used in Sn–Pb perovskite solar cells (PSCs) due to its many advantages, including high optical transparency, suitable conductivity, superior wettability, and so on. However, the acidic and hydroscopic properties of the PSS component, as well as the incongruous energy level of the hole transport layer (HTL), may...
NiFe‐based (oxy)hydroxides are the benchmark catalysts for the oxygen evolution reaction (OER) in alkaline medium, however, it is still challenging to control their structures and compositions. Herein, molybdates (NiFe(MoO4)x) are applied as unique precursors to synthesize ultrafine Mo modified NiFeOxHy (oxy)hydroxide nanosheet arrays. The electrochemical activation process enables the molybdate ions...
Precise control of molecular assembly is of great significance in the application of functional molecules. This work has systematically investigated the humidity effect in bubble‐assisted molecular assembly. This work finds humidity is critical in the evolution of the soft confined space, leading to the formation of microscale liquid confined space under high humidity, and nanoscale liquid confined...

Mechanoluminescence (ML) materials present widespread applications. Empirically, modulation for a given ML material is achieved by application of programmed mechanical actuation with different amplitude, repetition velocity and frequency. However, to date modulation on the ML is very limited within several to a few hundred hertz low‐frequency actuation range, due to the paucity of high‐frequency mechanical...
Copper is known as a conductive metal but an inert catalyst for the hydrogen evolution reaction due to its inappropriate electronic structure. In this work, an active copper catalyst is prepared with high‐energy surfaces by adopting the friction stir welding (FSW) technique. FSW can mix the immiscible Fe and Cu materials homogenously and heat them to a high temperature. Resultantly, α‐Fe transforms...
Since the advent of graphene ushered the era of 2D materials, many forms of hydrogenated graphene have been reported, exhibiting diverse properties ranging from a tunable bandgap to ferromagnetic ordering. Patterned hydrogenated graphene with micron‐scale patterns has been fabricated by lithographic means. Here, successful millimeter‐scale synthesis of an intrinsically honeycomb‐patterned form of...
Core‐Shell Upconverting Nanocrystals
This cover shows that critical information regarding the interface of core‐shell upconverting nanocrystals can be revealed (cracked sphere in the foreground) by implementing complementary STEM‐based methods with atomic‐scale resolution (inclined plane in the background). Depending on the shell growth conditions, core‐shell upconverting nanocrystals are characterized...
Advances in controlling energy migration pathways in core‐shell lanthanide (Ln)‐based hetero‐nanocrystals (HNCs) have relied heavily on assumptions about how optically active centers are distributed within individual HNCs. In this article, it is demonstrated that different types of interface patterns can be formed depending on shell growth conditions. Such interface patterns are not only identified...
Acute kidney injury (AKI) is frequently triggered by abundant reactive oxygen/nitrogen species (RONS) and leads to high morbidity and mortality in clinic. Unfortunately, the current clinical treatment options are only limited to supportive care, and hence, the development of nano‐antioxidants with high kidney enrichment is an attractive novel strategy for AKI management. Herein, self‐assembled ultrasmall...
