AbstractProton exchange membrane (PEM) electrolysis holds great promise for green hydrogen production, but suffering from high loading of platinum‐group metals (PGM) for large‐scale deployment. Anchoring PGM‐based materials on supports can not only improve the atomic utilization of active sites but also enhance the intrinsic activity. However, in practical PEM electrolysis, it is still challenging to mediate hydrogen adsorption/desorption pathways with high coverage of hydrogen intermediates over catalyst surface. Here, operando generated stable palladium (Pd) hydride nanoclusters anchored on tungsten carbide (WCx) supports were constructed for hydrogen evolution in PEM electrolysis. Under PEM operando conditions, hydrogen intercalation induces formation of Pd hydrides (PdHx) featuring weakened hydrogen binding energy (HBE), thus triggering reverse hydrogen spillover from WCx (strong HBE) supports to PdHx sites, which have been evidenced by operando characterizations, electrochemical results and theoretical studies. This PdHx‐WCx material can be directly utilized as cathode electrocatalysts in PEM electrolysis with ultralow Pd loading of 0.022 mg cm−2, delivering the current density of 1 A cm−2 at the cell voltage of ~1.66 V and continuously running for 200 hours without obvious degradation. This innovative strategy via tuning the operando characteristics to mediate reverse hydrogen spillover provide new insights for designing high‐performance supported PGM‐based electrocatalysts.

AbstractHigh‐voltage dual ion battery (DIB) is promising for stationary energy storage applications owing to its cost‐effectiveness, which has been a hot topic of research in rechargeable battery fields. However, it still suffers from rapid battery failure caused by the severe solvent co‐intercalation and electrolyte oxidation. To address these bottlenecks, herein a functional electrolyte additive hexafluoroglutaric anhydride (HFGA) is presented based on a Helmholtz plane regulation strategy. It is demonstrated that the HFGA can precisely enter into the Helmholtz plane and positively regulate anion solvation behaviors near the graphite electrode surface owing to its considerable H−F affinity with ethyl methyl carbonate (EMC), thus alleviating EMC‐related co‐intercalation and oxidation decomposition during DIB charging. Meanwhile, HFGA can copolymerize with the presence of PF5 at the Helmholtz plane to participate in forming a CF2‐rich CEI layer with excellent PF6− permselectivity, conducive to achieving PF6− de‐solvation and simultaneously suppressing electrolyte oxidation decomposition. By virtue of such beneficial effects, the graphite cathode enables a 5.5 V DIB with a prominent capacity retention of 92 % and a high average Coulombic efficiency exceeding 99 % within 2000 cycles at 5 C, demonstrating significantly enhanced electrochemical reversibility. The Helmholtz plane regulation strategy marks a milestone in advancing DIB technologies.

AbstractBenzo[1,3,2]dithiazole‐1,1,3‐trioxides are bench‐stable and easy‐to‐use reagents. In photoredox catalysis, they generate methyl and perdeuteromethyl radicals which can add to a variety of radical acceptors, including olefins, acrylamides, quinoxalinones, isocyanides, enol silanes, and N‐Ts acrylamide. As byproduct, a salt is formed which can be regenerated to the original methylating agent. Flow chemistry provides an option for reaction scale‐up further underscoring the synthetic usefulness of these methylation reagents. Mechanistic investigations suggest a single‐electron transfer (SET) pathway induced by photoredox catalysis.

Published: September 2024

AbstractModulating charge transfer (CT) interactions between donor and acceptor molecules may give rise to unique dynamic changes in physicochemical properties, exhibiting great importance in supramolecular chemistry and materials science. In this work, we demonstrate the first instance of reversible photomodulation of donor‐acceptor (D−A) CT interaction in the solid state. Pyridinium‐based chromophore featuring π‐conjugated D−A structures can not only function as a good electron acceptor to undergo photoinduced electron transfer (ET) or engage in intermolecular CT interaction, but also exhibit unique dual emission depending on the excitation wavelengths. The rotatable C−C single bonds within D−A pairs enhance the tunability of molecular structure. Through the synergy of a photoinduced ET and an excited‐state conformational change, the intermolecular CT interaction can be switched on and off by alternate light irradiation to enable reversibly modulation of the affinity between donor and acceptor molecules, accompanied by visual color switching and fluorescence on‐off as feedback signals.

AbstractOrganic‐inorganic metal halides (OIMHs) have become a research hotspot in recent years due to their excellent luminescent properties and tunable emission wavelengths. However, the development of efficient red‐light‐emitting OIMHs remains a significant challenge. This work reports three Mn‐based OIMHs derived from 1‐methyl‐1,2,3,4‐tetrahydroisoquinoline hydrobromide: racemic one (Rac‐TBM) and chiral ones (R‐TBM and S‐TBM). As a result of the synergism of chiral organic ligands inducing a unique lantern‐shaped hybrid structure containing both tetrahedra and octahedra, Rac‐TBM exhibits red‐light emission with near‐unity luminescence quantum yield. In comparison, the chiral counterparts R/S‐TBM display strong green emission and circularly polarized luminescence (CPL) with a glum value up to ±2.5×10−2. Interestingly, a mixture of R‐ and S‐TBM can transform into Rac‐TBM, successfully achieving a sensitive and reversible switch between red light of octahedra and green light of tetrahedra under external stimuli. The outstanding luminescent properties allow Rac‐TBM to be utilized not only for X‐ray radioluminescence with a detection limit down to 46.29 nGys−1, but also for advanced information encryption systems to achieve leak‐proof decryption.

ABSTRACTThe design, synthesis, and spectroscopic characterization of [Ag(P(o‐C6H4OCH3)3)(NO3)]2 (1) and [Ag(P(o‐C6H4OCH3)3)2][NO3] (2) were conducted to investigate the efficiency of the fabricated solar cell devices. The slow evaporation technique proved effective in growing the colorless crystals of the silver(I) complexes. Spectroscopic analyses including Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and ultraviolet–visible (UV–Vis) studies were carried out to elucidate the chemical structure and absorption properties of the compounds. The chemical composition and existence of intermolecular interactions in 1 and 2 were disclosed via the single‐crystal x‐ray diffraction method. The side‐to‐side arrangement of molecules in 1 and 2 was evident from the crystal packing analysis, in which the molecules in both compounds were linked together by C–H···O and C–H···π contacts. The silver(I) complexes exhibited maximum absorption wavelength (287–288 nm) within the ultraviolet region, where both compounds had comparable high energy band gap values ranging from 4.15 to 4.16 eV. Moreover, both compounds possess appropriate HOMO–LUMO energy levels that facilitate effective electron injection and dye regeneration processes in dye‐sensitized solar cell (DSSC) applications. Photophysical characterization techniques, field‐emission scanning electron microscopy (FESEM), and energy‐dispersive x‐ray (EDX) spectroscopy studies were employed to assess the morphological characteristics and elemental composition of the silver(I) complexes on TiO2. Compound 2 exceeded 1 in terms of solar cell efficiency, 2 (η = 3.34%) > 1 (η = 0.66%) due to the complex being in ionic form and composed of the mononuclear [Ag(P(o‐C6H4OCH3)3)2]+ cation [NO3]− anion.

AbstractFiber separation technology has been widely used in the removal of metal ions, dyes, proteins, and particles. In this work, the reversible characteristic of temperature sensitive hydrogel which possesses the expansion and contraction at different temperature is used to control the change of internal pores of filter materials for achieving the selective separation and concentration of solution. We prepared polylactic acid (PLA) hollow fiber as outer support layer by the template method and PLA electrospun membrane as internal support diaphragm by electrospinning. Then, the method of adding poly(N‐isopropylacrylamide) (PNIPAM) hydrogel in the hollow fiber layer by layer was adopted to form the hydrogel/PLA fiber. When the mass ratio of PNIPAM/PLA was 3/1, the sample presented the relatively tight interior morphology and was selected for protein separation. By adjusting the temperature, the rejection capacities of PNIPAM/PLA composite fiber for bovine serum albumin (BSA), and ovalbumin (OVA) were in the range of 25–36 mg/g and 22–31 mg/g, respectively. Furthermore, the fiber reusability was investigated by swelling and deswelling elution processes. It was found that the sample could be reused 5 times. This work explores a novel control method for the graded filtration and concentration of targets.

AbstractPolyethylene (PE) foams are widely used for the advantages of light weight and reducing energy consumption. So, the preparation of environmental friendly and efficient blowing agent is essential. The use of supercritical carbon dioxide (CO2) as physical blowing agent requires harsh experimental conditions such as high‐pressure and temperature. In this study, CO2 was captured by 1, 2‐cyclohexanediamine (TRK) under atmospheric pressure, and reversibly released under heating as a blowing agent with nanosponges (NS) used as the carrier (NS:TRK‐CO2). Furthermore, three ethoxy silane coupling agents were selected to improve the compatibility between heterogeneous nucleating agent (cyclodextrin nanosponges, NS) and PE, so as to improve the nucleation effect of NS and the comprehensive properties of PE composites. Analyses showed that triethoxyvinyl silane (VTES) was a suitable candidate for improving the compatibility of NS and PE. The addition of NS:TRK‐CO2@VTES not only improved the crystallization performance, but also improved the complex viscosity and storage modulus, and enhanced the thermal properties of PE composites. The optimal cell morphology was obtained by introduction of NS:TRK‐CO2@VTES with 5 wt%, the minimum cell diameter was 50 μm, and the maximum cell density was 9.4 × 104 cells/cm3. Compared with the other PE composites, PE/NS:TRK‐CO2@VTES composites showed excellent mechanical, thermal, and sound insulation properties. The maximum impact strength was 7.62 KJ/m2, which was two times higher than pure PE. The thermal conductivity was 0.054 W/m k, the sound absorption coefficient was 0.836 at 1500 Hz.

AbstractThe new energy market is growing rapidly, lithium batteries (LBs) as the most important source of energy supply in the energy storage and power market, has higher requirements for fast charge and long life, so it is necessary to improve the cell voltage and energy density of LBs. However, LBs with high voltage and high energy density will face serious challenges of electrolyte decomposition and electrode corrosion in high voltage environment. Herein, this review summarizes the effects of a series of sultones as electrolyte additives in high voltage electrolytes. It is found that DTD, ES, 1,3‐PS, PES, PCS, MMDS, BDTD, BDTT, DTDph, ODTO, FPS, VES and other sultones have excellent properties on stabilizing SEI/CEI formation, inhibiting gas production, and good high temperature resistance. The preferential oxidation/reduction of sultones can protect the electrolyte from decomposition, and the uniform and dense SEI/CEI can also promote Li+ transport, protect the electrode from corrosion, prevent the growth of lithium dendrites, and promote the insertion and removal of Li+, so as to improve the cycle life of the high‐voltage battery. Therefore, sultones are very suitable as high‐voltage LBs electrolyte additives to improve the performance of cells. This review can provide theoretical support for the design of high voltage and high energy density LBs electrolyte and selection of additives in the future.

AbstractThis study aimed to improve the production of biodiesel from white palm larvae (WPL) and to evaluate its potential as a feedstock. The larvae were grown using kitchen and palm waste for 21 days, and the crude oil was then extracted. The extracted oil was analyzed for its physicochemical properties and fatty acid composition. The analysis found that the feedstock oil contained a high quantity of monounsaturated fatty acids, indicating its suitability for biodiesel production. To optimize the production process, response surface methodology (RSM) was employed. A central composite design was used to study four operating conditions: temperature, methanol‐to‐oil mole ratio, esterification time, and catalyst loading for esterification, as well as transesterification time and catalyst concentration. The best conditions for esterification were a methanol‐to‐oil ratio of 18:1, a temperature of 70 °C, 120 min of reaction time, and a 4% H2SO4 catalyst. For transesterification, the optimal conditions were a methanol‐to‐oil ratio of 10:1, a temperature of 65 °C, 90 min of reaction time, and a 2% KOH catalyst concentration. The experimental data fit well with models, with significant P‐values and high R2 values. The biodiesel produced under the optimized conditions met the fuel quality standards set by Brazilian, European, and American standards. In conclusion, this study successfully optimized the biodiesel production process from white palm larvae and confirmed its suitability as a feedstock. The feedstock oil had properties that were suitable for biodiesel production, and the optimized conditions resulted in biodiesel that met fuel‐quality standards.
Increasing photogalvanic solar power generation and storage capacity of brilliant cresyl blue by employing surfactant and natural sunlight
Authors: Koli Pooran 
Published: September 2024

AbstractPhotogalvanic solar cells are solar energy harvesting devices having inherent power storage capacity. Electrical output as 590 μA current, 183.3 μW power, and 1.95% efficiency is reported for the fructose/brilliant cresyl blue dye (a reductant/photosensitizer couple) at low illumination intensity. For exploring the feasibility of these cells for application, the reported electrical output needs further enhancement with the demonstration of workability in natural sunlight. With this aim, the modified fructose reductant‐NaOH alkali‐brilliant cresyl blue dye photosensitizer photogalvanic system has been studied using a surfactant with a very small Pt electrode in natural sunlight. Abruptly enhanced current (2300 μA), power (661 μW), and efficiency (8.26%) have been observed in the modified study. The study has shown that photogalvanic cells can work at high illumination intensity adhering to similar basic principles, which are apt for cells working at artificial and low‐intensity illumination.

AbstractWalnut yield and quality are often affected by beetle infestations, particularly those caused by Carpophilus truncatus (Murray) (Nitidulidae) and Oryzaephilus mercator (L.) (Silvanidae). Beetle damage exposes walnuts to microbial food spoilers such as Fusarium species. Insecticides currently used for beetle control are environmentally unfriendly. This work explored a green synthesis approach for copper oxide nanoparticles (CuO−NPs) in a basic medium at 30 °C by hydrolates, aqueous extracts obtained from Lippia integrifolia and Pimpinella anisum, denoted as CuO−I and CuO−A, respectively. Characterization through XRD, FT‐IR, Raman, UV‐visible absorbance, and AFM techniques indicated that CuO−A and CuO−I have a size ranging from 2–10 nm in height. The antifungal assay showed that both have a similar efficacy (MID=320 μg), 3‐fold stronger than CuO‐ NPs obtained in absence of hydrolates (denoted CuO−W) (MID=960 μg), with the broadest inhibitory halos (ID=126–128 mm) observed for CuO−A. Insecticidal activity of CuO−NPs showed a concentration‐dependent behavior, with CuO−I showing an effect comparable to that of diatomaceous earth. SEM images confirmed the adhesion of nanoparticles to insect surfaces, which could induce oxygen deprivation and disruption of metabolic processes. Both CuO−A and CuO−I are promising for their use in integrated pest control in walnut storage.

Published: September 2024

ABSTRACTApelin, a bioactive peptide that serves as an endogenous ligand for the apelin receptor (APJ), is overexpressed in various types of cancers and contributes to cancer cell proliferation, viability, migration, angiogenesis, and metastasis, as well as immune deviation. Noncoding RNAs (ncRNAs) regulate gene expression, and there is growing evidence suggesting a bidirectional crosstalk between ncRNAs (including long noncoding RNAs [lncRNAs], circular RNAs [circRNAs], and microRNAs [miRNAs]) and apelin in cancers. Certain miRNAs can directly target the apelin and inhibit its expression, thereby suppressing tumor growth. It has been indicated that miR‐224, miR‐195/miR‐195‐5p, miR‐204‐5p, miR‐631, miR‐4286, miR‐637, miR‐4493, and miR‐214‐3p target apelin mRNA and influence its expression in prostate cancer, lung cancer, esophageal cancer, chondrosarcoma, melanoma, gastric cancer, glioma, and hepatocellular carcinoma (HCC), respectively. Moreover, circ‐NOTCH1, circ‐ZNF264, and lncRNA BACE1‐AS upregulate apelin expression in gastric cancer, glioma, and HCC, respectively. On the other hand, apelin has been shown to regulate the expression of certain ncRNAs to affect tumorigenesis. It was revealed that apelin affects the expression of circ_0000004/miR‐1303, miR‐15a‐5p, and miR‐106a‐5p in osteosarcoma, lung cancer, and prostate cancer, respectively. This review explains a bidirectional interplay between ncRNAs and apelin in cancers to provide insights concerning the molecular mechanisms underlying this crosstalk and potential implications for cancer therapy.

AbstractThis prospect explores the integration of enrichment strategies with nanopore detection to advance clinical glycoproteomics. Glycoproteins, crucial for understanding biological processes, pose challenges due to their low abundance and structural diversity. Enrichment techniques using lectin affinity, boronate affinity, and hydrazide chemistry and especially molecular imprinted polymers may selectively and specifically isolate glycoproteins from complex samples, while nanopore technology enables label‐free, real‐time, and single‐molecule analysis. This approach holds promise for disease‐related glycosylation studies, biomarker discovery, personalized medicine, and streamlined clinical analysis. Standardization, optimization, and data analysis remain challenges, requiring interdisciplinary collaborations and technological advancements. Overall, this integration may offer transformative potential for clinical glycoproteomics and innovative diagnostic and therapeutic strategies.
