Sustainable and scalable solar‐energy‐driven CO2 conversion into fuels requires earth‐abundant and stable photocatalysts. In this work, a defective Nb2C MXene as a cocatalyst and TiO2 microspheres as photo‐absorbers, constructed via a coulombic force‐driven self‐assembly, is synthesized. Such photocatalyst, at an optimized loading of defective Nb2C MXene (5% def‐Nb2C/TiO2), exhibits a CH4 production...
Solar‐Driven Desalination
In article number 2307005, Liming Wang, Xiaohong Qin, and co‐workers present an electrospun nanofiber‐based all‐in‐one vertically interfacial solar evaporator, endowed with a high steam generation rate, steady omnidirectional evaporation, and enduring ultrahigh‐salinity brine desalination. Salt ions can be effectively exchanged with the bulk water due to strong action of...
Solar‐driven interfacial desalination is widely considered to be a promising technology to address the global water crisis. This study proposes a novel electrospun nanofiber‐based all‐in‐one vertically interfacial solar evaporator endowed with a high steam generation rate, steady omnidirectional evaporation, and enduring ultrahigh‐salinity brine desalination. In particular, the electrospun nanofiber...
Tunnel oxide passivating contact (TOPCon) solar cells (SCs) as one of the most competitive crystalline silicon (c‐Si) technologies for the TW‐scaled photovoltaic (PV) market require higher passivation performance to further improve their device efficiencies. Here, the successful construction of a double‐layered polycrystalline silicon (poly‐Si) TOPCon structure is reported using an in situ nitrogen...
Space charge transfer of heterostructures driven by the work‐function‐induced built‐in field can regulate the electronic structure of catalysts and boost the catalytic activity. Herein, an epitaxial heterojunction catalyst of CoO/Mo2C with interfacial electron redistribution induced by work functions (WFs) is constructed for overall water splitting via a novel top‐down strategy. Theoretical simulations...
Photosensitive materials, such as energetic complexes, usually have high sensitivity and cause heavy‐metal pollution, whereas others, like carbon black and dye, do not contain energy, which affects energy output and mechanical properties. In this work, donor–acceptor π‐conjugated energetic catalysts, denoted as D‐n, are designed and synthesized. Nonmetallic hybrid energetic composites are prepared...
Metal‐Free Hybrid Energetic Composites
Donor–acceptor π‐conjugated energetic catalysts, denoted as D‐n, are developed, and nonmetallic hybrid energetic composites are prepared by assembling the as‐synthesized catalysts into multiscale ammonium perchlorate (AP), which can be ignited without the involvement of metals. At the voltage of 1 kV, the laser‐ignition delay time of D‐2/AP decreases from 56...
Achieving fast transmembrane transmission of molecules in organisms is a challenging problem. Inspired by the transport of Dopmine (DA) in organisms, the DA transporter (DAT) binds to DA in a way that has a ring recognition (the recognition group is the tryptophan group). Herein, D‐Tryptophan‐pillar[5]arene (D‐Trp‐P5) functionalized conical nanochannel is constructed to achieve fast transmission of...
The precise regulation of chiral drug transmembrane transport can be achieved through drug transporters in living organisms. However, implementing this process in vitro is still a formidable challenge due to the complexity of the biological systems that control drug enantiomeric transport. Herein, a facile and feasible strategy is employed to construct chiral L‐tyrosine‐modified nanochannels (L‐Tyr...
Probing endogenous molecular profiles in living entities is of fundamental significance to decipher biological functions and exploit novel theranostics. Despite programmable nucleic acid‐based aptasensing systems across the breadth of molecular imaging, an aptasensing system enabling in vivo imaging with high sensitivity, accuracy, and adaptability is highly required yet is still in its infancy. Artificial...
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...
Developing highly active electrocatalysts toward oxygen evolution reaction (OER) is critical for the application of water splitting for hydrogen production and can further alleviate the energy crisis problem, but still remaining challenging. Especially, unlocking the catalytic site, in turn, helps design the available catalysts. Herein, the nanorod cobalt telluride with sulfur incorporation grown...
Nanoparticle‐based tumor immunotherapy has emerged to show great potential for simultaneously regulating the immunosuppressive tumor microenvironment, reducing the unpleasant side effects, and activating tumor immunity. Herein, an excipient‐free glutathione/pH dual‐responsive prodrug nanoplatform is reported for immunotherapy, simply by sequentially liberating 5‐aminolevulinic acid and immunogenically...
Mitochondria‐mediated apoptosis (MMA) is a preferential option for cancer therapy due to the presence of cell‐suicide factors in mitochondria, however, low permeability of mitochondria is a bottleneck for targeting drug delivery. In this paper, glycyrrhetinic acid (GA), a natural product from Glycyrrhiza glabra, is found to be a novel mitochondria targeting ligand, which can improve mitochondrial...
