Summary: This article presents an ink-jet printed ultrahigh-frequency (UHF) radio frequency identification (RFID) label for tagging fruits. The proposed tag antenna is based on a hybrid configuration, which consists of a loop, dipole-like strips (DLSs), and eye-shaped rectangular nested slots. The loop fulfills impedance matching proposes, while the eye-shaped slots assist to maintain high imaginary impedance to mitigate capacitive effects of high permittivity surfaces of fruits. The fabricated prototype of the proposed tag antenna achieved a read range of 3 m after mounting on apple. Moreover, the tag antenna is also tested for sensing spoilage of apple fruits.

Summary: A precise synthesis strategy is proposed to stabilize single atomic ruthenium on nickel vanadium layered double hydroxides (NiV-LDH) ultrathin nanoribbons support. The resulting NiVRu-R catalyst demonstrates superior catalytic properties for electrocatalytic hydrogen evolution reaction (HER) in alkaline media, outperforming the commercial Pt/C catalyst. The stability of NiVRu-R is maintained even after 5,000 cyclic voltammetry cycles, which is attributed to the Ru atomic sites stabilized on supports through the Ru-O-V structure.

Summary: The electronically asymmetric Cu-Cu/Cu-N-C interface site enhances the adsorption of *CO intermediates and lowers the reaction barrier of C-C coupling in electrochemical CO2 reduction (ECR), enabling efficient C-C coupling at low overpotential. The high-density Cu/CuNC interface sites (ER-Cu/CuNC) catalyst boosts the electrocatalytic CO2-to-ethanol conversion with a Faradaic efficiency toward C2+ of 60.3% (FEethanol of 55%) at a low overpotential of -0.35 V. These findings provide new insights into the efficient conversion of CO2 to C2+ products.

Summary: In recent years, nanozymes with high activity and stability have been considered as potential alternatives to natural enzymes. However, the relationship between electronic metal-support interactions (EMSI) and catalytic performance in nanozymes is still unclear. In this study, a copper nanoparticle nanozyme supported on N-doped Ti3C2Tx was successfully synthesized, and the modulation of EMSI was achieved by introducing N species. The stronger EMSI between Cu NPs and Ti3C2Tx significantly enhanced the catalytic performance of the nanozyme.

Summary: In this study, novel electrocatalysts with individually dispersed Pt active sites and tunable Pt-Ni interaction were developed. The Pt/Ni-DA catalyst exhibited superior performance for the hydrogen evolution reaction (HER), with an ultralow overpotential of 18 mV at 10 mA cm(-2) and an ultrahigh mass activity of 2.13 A mg(Pt) (-1) at an overpotential of 50 mV, which is about four times higher than that of commercial Pt/C. X-ray absorption fine structure (XAFS) confirmed the diffusion of Pt from the Ni surface to the Ni bulk phase. Mechanistic research and density functional theory (DFT) calculations revealed that the dispersibility and distribution of Pt atoms in Ni regulate the electronic configuration of Pt sites, optimizing the binding energy of reaction intermediates and facilitating electron transfer during the HER process. This work highlights the importance of electronic structure alteration through the accommodation effect for enhanced catalytic performance in HER.

Summary: Different amounts of B2O3 were added to Ce3+-doped Gd2O3-Al2O3-SiO2 glasses to enhance their photoluminescence and scintillation properties. The addition of Si3N4 effectively reduced Ce4+ to Ce3+ in the glasses. Increasing the B2O3 content resulted in a blue shift in the excitation and emission spectra. The photoluminescence quantum yield increased with B2O3 content, reaching a maximum of 59.55% at x = 15. The glasses exhibited good luminescent thermal stability and comparable X-ray excited luminescence intensity to Bi4Ge3O12 crystal.

Summary: This study reports a single-atom Au loaded MgAl-layered double hydroxide (Au-1-MgAl-LDH) catalyst, which is capable of driving the oxidation of benzene with O2 in water with a high selectivity of 99% for phenol. The selectivity difference between Au-1-MgAl-LDH and Au nanoparticle loaded MgAl-LDH (Au-NP-MgAl-LDH) can be attributed to the profound adsorption behavior of substrate benzene with Au single atoms and nanoparticles.

Summary: In this study, two different nickel single-atom catalysts (Ni-SACs) were constructed on WO2.72 nanowires, including bulk doping of single Ni atoms in WO2.72 (B-Ni-1/WO2.72) and surface anchoring of single Ni atoms on WO2.72 (S-Ni-1/WO2.72), to explore the electronic structure manipulation for enhancing CO2 photoreduction. The results showed that B-Ni-1/WO2.72 exhibited superior photocatalytic performance compared to S-Ni-1/WO2.72, achieving a CO yield of 80.5 mmol g(-1) h(-1) with a selectivity of 98.7%.

Summary: In this study, self-reduction from Mn4+ to Mn2+ was achieved in a borate alpha-LiZnBO3 with planar triangle [BO3] as the basic building unit. The borate-based phosphor exhibited typical Mn2+ emission in ambient atmosphere. X-ray absorption fine structure, X-ray photoelectron spectroscopy, and electron paramagnetic resonance confirmed the divalent state of doped ions. Oxygen vacancies formed during synthesis process and lithium vacancies introduced by heterovalent substitution were identified as the decisive factors in the valence state-transition of doped ions. This study provided a new perspective on self-reduction system, deepened the understanding of self-reduction mechanism, and expanded the possibilities for developing novel optical functional materials through defect control.

Summary: A general method for designing electrocatalysts for water splitting is proposed, which involves the generation of oxygen vacancies in bimetallic layered double hydroxides using carbon nitride. The high OER activity of these bimetallic layered double hydroxides is attributed to the presence of oxygen vacancies, which lower the energy barrier of the rate-determining step.
