Indoor Photovoltaics
In article number 2203768, Paola Vivo and co‐workers propose the use of low‐toxicity copper‐silver‐bismuth iodide (Cu2AgBiI6) light‐harvester for indoor photovoltaics (IPVs). When treating Cu2AgBiI6 with hydroiodic acid, the film morphology is enhanced, leading to IPVs with a power conversion efficiency up to 4.7%.
Lead‐free perovskite‐inspired materials (PIMs) are gaining attention in optoelectronics due to their low toxicity and inherent air stability. Their wide bandgaps (≈2 eV) make them ideal for indoor light harvesting. However, the investigation of PIMs for indoor photovoltaics (IPVs) is still in its infancy. Herein, the IPV potential of a quaternary PIM, Cu2AgBiI6 (CABI), is demonstrated upon controlling...
Thin‐film lithium niobate platform, namely lithium‐niobate‐on‐insulator (LNOI), brings new opportunities for integrated photonics, taking advantages from both outstanding crystalline properties and special structural features. The excellent properties of LNOI have triggered development of a variety of on‐chip photonic devices for light generation and manipulation. However, as an indispensable component...
Smart modulation of bioelectric signals is of great significance for the development of brain‐computer interfaces, bio‐computers, and other technologies. The regulation and transmission of bioelectrical signals are realized through the synergistic action of various ion channels in organisms. The bionic nanochannels, which have similar physiological working environment and ion rectification as their...
Engineering Pt‐free catalysts for hydrogen evolution reaction (HER) with high activity and stability is of great significance in electrochemical hydrogen production. Herein, in situ chemical H intercalation into ultrafine Pd to activate this otherwise HER‐inferior material to form the ultrafine IrPdH hydride as an efficient and stable HER electrocatalyst is proposed. The formation of PdIrH depends...
Ocean acidification is considered detrimental to marine calcifiers, but mounting contradictory evidence suggests a need to revisit this concept. This systematic review and meta‐analysis aim to critically re‐evaluate the prevailing paradigm of negative effects of ocean acidification on calcifiers. Based on 5153 observations from 985 studies, many calcifiers (e.g., echinoderms, crustaceans, and cephalopods)...
Heavy metal pollution has resulted in numerous environmental challenges. However, classic approaches, involving the use of solid adsorbents are subject to limitations, including the high energy consumption required for processing before and after use. Accordingly, strategies that facilitate the use of metal capture media that extends beyond waste remediation are attractive. Herein, a porous fluorescent...
Rapid, accurate, and sensitive insulin detection is crucial for managing and treating diabetes. A simple sandwich‐type electrochemical immunosensor is engineered using gold nanoparticle (AuNP)‐adhered metal–organic framework‐derived copper–zinc hollow porous carbon nanocubes (Au@Cu5Zn8/HPCNC) and AuNP‐deposited nitrogen‐doped holey graphene (NHG) are used as a dual functional label and sensing platform...
Laser is a powerful tool for the synthesis of nanomaterials. The intensive laser pulses delivered to materials within nanoseconds allow the formation of novel structures that are inaccessible for conventional methods. Layered double hydroxide (LDH) nanostructures with high porosity, suitable dopants, and rich defects are desirable for catalysts, however, tremendously difficult in a one‐pot synthesis...
High‐sensitivity nanomechanical sensors are mostly based on silicon technology and related materials. The use of functional materials, such as complex oxides having strong interplay between structural, electronic, and magnetic properties, may open possibilities for developing new mechanical transduction schemes and for further enhancement of the device performances. The integration of these materials...
To realize excellent selectivity of CH4 in CO2 photoreduction (CO2PR) is highly desirable, yet which is challenging due to the limited active sites for CH4 generation and severe electron‐hole recombination on photocatalysts. Herein, based on the theoretically calculated effects of vanadium incorporation into the laminate of layered double hydroxides (LDHs), V into NiAl‐LDH to synthesize a series of...
Motivated by simplifying the synthesis of nonfullerene acceptor and establishing the relation between molecular structure and photovoltaic performance, two isomeric nonfused ring electron acceptors (o‐TT‐Cl and m‐TT‐Cl), whose properties can be adjusted by changing the side chains, are designed and synthesized with several high‐yield steps. o‐TT‐Cl with V‐shaped side chain induces a dominated J‐aggregation...
News from an old acquaintance: The streptavidin (STV)‐biotin binding system is frequently used for the decoration of DNA origami nanostructures (DON) to study biological systems. Here, a surprisingly high dynamic of the STV/DON interaction is reported, which is affected by the structure of the DNA linker system. Analysis of different mono‐ or bi‐dentate linker architectures on DON with a novel high‐speed...
As a core component, the catalyst layer (CL) is widely used in fuel cell, metal‐air battery, and other energy conversion devices. Herein, a highly efficient method for CL preparation via fast current‐driven synthesis followed by pyrolysis is proposed. Compared with previously reported fabrication procedures of zeolite imidazolate frameworks (ZIF)‐based CLs, this method directly deposits the ZIF precursor...
MRSA Phototherapy
In article number 2203292, Weiliang Xia, Yingzheng Zhao, Yijie Chen, and co‐workers show that Van‐Lipo(IR780)‐PFC (an oxygen‐carrying perfluorocarbon nanoemulsion stabilized by a vancomycin‐functionalized sphingo‐myelin liposome loaded with IR780) can capture methicillin‐resistant Staphylococcus aureus (MRSA) toxins in situ, resulting in the on‐demand release of phototherapeutic...
Transition metal nanostructures are widely regarded as important catalysts to replace the precious metal Pt for hydrogen evolution reaction (HER) in water splitting. However, it is difficult to obtain uniform‐sized and ultrafine metal nanograins through general high‐temperature reduction and sintering processes. Herein, a novel method of chemical energy‐driven lithiation is introduced to synthesize...
Compared with the traditional holographic technology, metasurface holography is a promising technology due to the large field angle and high spatial resolution. Thanks to the precise control of phase, amplitude, polarization and so on, metasurface holography provides a flexible platform for light modulation, optical encryption and so on. Besides, the process of image reconstruction by single pixel...
Silicon is one of the most promising anode materials for lithium‐ion batteries. However, the huge volume change of silicon during lithiation/delithiation triggers continuous growth of solid‐electrolyte interphase, loss of conductive contacts and structural collapse of the electrode, which causes a rapid deterioration of battery capacities. Inspired by the polyaromatic molecular nature and phase separation...
