Renewable energy storage using electrochemical storage devices is extensively used in various field applications. High‐power density supercapacitors and high‐energy density rechargeable batteries are some of the most effective devices, while lithium‐ion batteries (LIBs) are the most common. Due to the scarcity of Li resources and serious safety concerns during the construction of LIBs, development...
Programmable, custom‐shaped, and nanometer‐precise DNA origami nanostructures have rapidly emerged as prospective and versatile tools in bionanotechnology and biomedicine. Despite tremendous progress in their utilization in these fields, essential questions related to their structural stability under physiological conditions remain unanswered. Here, DNA origami stability is explored by strictly focusing...
The development of long‐lived electrochemical energy storage systems based on renewable materials is integral for the transition toward a more sustainable society. Supercapacitors have garnered considerable interest given their impressive cycling performance, low cost, and safety. Here, the first example of a chiral nematic activated carbon aerogel is shown. Specifically, supercapacitor materials...
Herein, an integrated structure of single Fe atom doped core‐shell carbon nanoboxes wrapped by self‐growing carbon nanotubes (CNTs) is designed. Within the nanoboxes, the single Fe atom doped hollow cores are bonded to the shells via the carbon needles, which act as the highways for the electron transport between cores and shells. Moreover, the single Fe atom doped nanobox shells is further wrapped...
A porous liquid crystalline elastomer actuator filled with an ionic liquid (PLCE‐IL) is shown to exhibit the functions of two classes of materials: electrically responsive, deformable materials for sensing and soft active materials for stimuli‐triggered actuation. On one hand, upon the order–disorder phase transition of aligned mesogens, PLCE‐IL behaves like a typical actuator capable of reversible...
Single‐atom catalysts (SACs) for photocatalytic hydrogen peroxide (H2O2) generation are researched but it is still challenging to obtain high H2O2 yields. Herein, graphite carbon nitride (FeSA/CN) confined single Fe atoms with N/O coordination is prepared, and FeSA/CN shows high H2O2 production via oxalic acid and O2 activation. Under visible light illumination, the concentration of H2O2 generated...
In this study, silver nanowires (Ag NWs) are synthesized at first, and then the 1D heterogeneous Co/C@Ag NWs with a kebab‐ and popsicle‐like microstructures are constructed by in situ growth ZIF‐67 on Ag NWs combined with calcination. Results show that the EM wave prevention performance of composites depends on the loading of Co/C particles threaded on the Ag NWs. The popsicle‐like structure with...
By arranging fluorophores in a directional way on a 2D DNA nanosheet that transfers energy from the initial donor to the acceptor through homogeneous Förster resonance energy transfer (homo‐FRET), it is found that the photonic wires (PWs) based on cascade long‐range resonance energy transfer (LrRET) up to 15.6 nm can be effectively achieved through the rational selection of the fluorophores and the...
The cell membrane permeabilization ability of immune defense antimicrobial peptides (AMPs) is widely applied in biomedicine. Although the mechanisms of peptide–membrane interactions have been widely investigated, analyses at the molecular level are still lacking. Herein, the membrane‐specific action of a native AMP, As‐CATH4, is investigated using a single‐lipid tracking method in combination with...
Solar‐driven CO2 conversion into valuable fuels is a promising strategy to alleviate the energy and environmental issues. However, inefficient charge separation and transfer greatly limits the photocatalytic CO2 reduction efficiency. Herein, single‐atom Pt anchored on 3D hierarchical TiO2‐Ti3C2 with atomic‐scale interface engineering is successfully synthesized through an in situ transformation and...
Recent studies have found that the existence of oxygen around the active sites may be essential for efficient electrochemical CO2‐to‐CO conversion. Hence, this work proposes the modulation of oxygen coordination and investigates the as‐induced catalytic behavior in CO2RR. It designs and synthesizes conjugated phthalocyanine frameworks catalysts (CPF‐Co) with abundant CoN4 centers as an active source,...
The epidemics caused by the influenza virus are a serious threat to public health and the economy. Adding appropriate adjuvants to improve immunogenicity and finding effective mucosal vaccines to combat respiratory infection at the portal of virus entry are important strategies to boost protection. In this study, a novel type of core/shell protein nanoparticle consisting of influenza nucleoprotein...
Highly active bifunctional electrocatalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) have always been the key factors to affect the performance of zinc–air batteries. However, integrating the independent reaction sites of ORR and OER in a catalyst remains a major challenge. Herein, a collaborative strategy based on defect induction and doping is proposed to prepare the...
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...
A superior composite material consisting of MXene and ruthenium dioxide‐modified carbon cloth is synthesized by pulsed laser deposition and electrostatic self‐assembly, which is further utilized to construct a class of novel electrochemical (EC) sensors for kaempferol (KA) detection. The carbon‐cloth‐based electrodes modified by ruthenium dioxide and then MXene are characterized by X‐ray diffraction,...
Pentagon–heptagon embedded polycyclic aromatic hydrocarbons (PAHs) have aroused increasing attention in recent years due to their unique physicochemical properties.

In the solid state of BN‐2, two different...
2D Dion–Jacobson (DJ) phase hybrid perovskites have shown great promise in the photoelectronic field owing to their outstanding optoelectronic performance and superior structural rigidity.
