In article number 2005159, Dong‐Pyo Kim, Hyomin Lee, and co‐workers present wax‐based Janus particles with dumbbell structures to simultaneously achieve enhanced emulsion stability and tunable thermal coalescence of these Janus particle‐stabilized emulsions. The wax‐based Janus particles enable particle‐adsorbed droplets to coalesce above a designated temperature, possessing great potential for various...
In article number 2005550, Shoji Takeuchi and co‐workers present a parallel lipid bilayer array with integrating series resistors for sensitive and resilient detection of toxin pore formation, illustrated by electrical signatures. This array will help in understanding toxic activity and development of diagnosis, treatment, and control of bacterial infections in medicine.
In article number 2004526, Chunhua Feng and co‐workers demonstrate that Cu catalysts minimized at the single‐atom level can overcome the limitations of nanoparticles and bulk materials in nitrate reduction reaction (NO3RR). These catalysts anchored on nitrogenated carbon nanosheets exhibit outstanding activity and stability for NO3RR and distinctly suppress the release of nitrite intermediate due...
In article number 2005185, Utkan Demirci and co‐workers present living immunocyte templated micromotors that demonstrate significantly increased surface interactions and efficient removal of various targets across multiple scales, from ions to cells, compared to smooth synthetic material templated micromotors with the same size and surface chemistry.
Compared with typical binary polymeric memory materials, functional polymers with ternary memory performance possess significant potential to achieve ultra‐high‐density data storage. The reported ternary memory polymers are normally driven by dual‐mechanism. However, the involved thermodynamically unstable mechanisms (field‐induced conformation change or conductive filament formation/fracture) may...
Integrating biological detection and treatment into one system is a smart therapeutic maneuver for efficient cancer treatment. Herein, a target‐activated core–satellite nanostructure (CS nanostructure) assembly built on gold nanobipyramids motor (AuNBPs motor)/gold nanoparticle probe (AuNP probe) exhibiting simultaneous dual signal‐on imaging, quantification of intracellular microRNA‐21 (miR‐21),...
A new microwave‐enhanced synthesis method for the production of tellurium nanostructures is reported—with control over products from the 1D regime (sub‐5 nm diameter nanowires), to nanoribbons, to the 2D tellurene regime—along with a new methodology for local statistical quantification of the crystallographic parameters of these materials at the nanometer scale. Using a direct electron detector and...
An artificial cell membrane is applied to study the pore formation mechanisms of bacterial pore‐forming toxins for therapeutic applications. Electrical monitoring of ionic current across the membrane provides information on the pore formation process of toxins at the single pore level, as well as the pore characteristics such as dimensions and ionic selectivity. However, the efficiency of pore formation...
Removing trace amounts of alkynes from alkenes is one of the most critical and challenging steps to produce high‐purity alkenes, the fundamental raw materials in petrochemical industry. Selective hydrogenation using noble metal catalysts under harsh conditions can convert trace alkynes to alkenes, but suffers from limited selectivity, over‐hydrogenation, and energy‐intensive consumption. Herein, the...
Nanoscale titanium nitride TiN is a metallic material that can effectively harvest sunlight over a broad spectral range and produce high local temperatures via the photothermal effect. Nanoscale indium oxide‐hydroxide, In2O3−x(OH)y, is a semiconducting material capable of photocatalyzing the hydrogenation of gaseous CO2; however, its wide electronic bandgap limits its absorption of photons to the...
Abundant reactive oxygen species and tumor necrosis factor‐α (TNF‐α) cytokine supply of M1‐type macrophages boost rheumatoid arthritis (RA) pathological process. For efficient RA therapy, here a multifunctional nanoplatform is presented based on generation 5 (G5) poly(amidoamine) dendrimer‐entrapped gold nanoparticles (Au DENPs) to achieve co‐delivery of antioxidant alpha‐tocopheryl succinate (α‐TOS)...
2D Si nanomaterials draw great interest owing to their fascinating properties and potential applications in electronic devices, catalysts, and energy storage and conversion devices. However, high‐quality and large‐scale synthesis of Si nanosheets remains a big challenge, despite the limited reports on their preparations via chemical exfoliation of layered Zintl silicide, magnesiothermic reduction...
Nucleic acid hybridization reactions play an important role in many (bio)chemical fields, for example, for the development of portable point‐of‐care diagnostics, and often such applications require nucleic acid‐based reaction systems that ideally run without enzymes under isothermal conditions. The use of novel capillary‐driven microfluidic chips to perform two isothermal nucleic acid hybridization...
Magnesium (Mg) metal anode is a highly desirable candidate among various high energy density metal anodes, possessing higher volumetric capacity and better safety characteristic compared to lithium metal. However, most Mg salts in conventional Mg electrolytes easily react with Mg metal to form blocking layers, leading to inferior reversibility of Mg plating/stripping. Here, a stable Mg2+‐conducting...
A new strategy that utilizes temperature‐responsive wax‐based Janus particles as microsurfactants to simultaneously achieve enhanced emulsion stability, as well as, on‐demand coalescence of emulsion droplets is presented. The dumbbell structure with different surface wetting properties on each side of the Janus particle enables the particles to strongly adsorb at the liquid–liquid interface, leading...
The rational modulation of the nontraditional intrinsic luminescence (NTIL) of nonconventional luminophores remains difficult, on account of the limited understanding on the structure–property relationships and emission mechanisms. Herein, the effective modulation of NTIL is demonstrated based on a group of nonaromatic anhydrides and imides. Mutual bridging of isolated subgroups effectively promotes...
Carbon nanodots (CDs) anchored onto inorganic supporter (amorphous nanosilica, SiO2) like a core‐satellite structure have enhanced the room‐temperature phosphorescence (RTP) intensity along with ultralong lifetime of 1.76 s. Special and quite stable structure should account for these superiorities, including hydrogen network, covalent bond, and trap‐stabilized triplet‐state excitons that are responsible...
The potassium ion batteries (KIBs) based on conversion/alloying reaction mechanisms show high theoretical capacity. However, their applications are hampered by the poor cyclability resulting from the inherent large volume variations and the sluggish kinetics during K+ repeated insertion/extraction process. Herein, taken Sb2Se3 as a model material, by rational design, nickel doped‐carbon coated Sb2...
The electrochemical CO2 reduction reaction (CO2RR) to syngas represents a promising solution to mitigate CO2 emissions and manufacture value‐added chemicals. Palladium (Pd) has been identified as a potential candidate for syngas production via CO2RR due to its transformation to Pd hydride under CO2RR conditions, however, the pre‐hydridized effect on the catalytic properties of Pd‐based electrocatalysts...
