ABSTRACTThe existence of organic pollutants in aqueous media has become a vital issue and a critical threat to human health, where organic toxic dyes represent the major contaminants in wastewater. Over the past few years, photocatalytic techniques have garnered a lot of interest in dye removal from wastewater. In this study, a series of ErxTbxZn1 − 2xO nanophotocatalysts (where x = 0.00, 0.01, 0.03, and 0.05) were synthesized and coded as ZET0, ZET1, ZET2, and ZET3 NPs (nanoparticles). The chemical and physical characteristics of the NPs were investigated using Fourier‐transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), energy‐dispersive X‐ray (EDX) spectroscopy, and ultraviolet–visible diffuse reflectance spectroscopy (UV–vis DRS) techniques. Further examination by performing photocatalytic experiments, ZET1 NPs demonstrated effective Rhodamine B (RhB) dye degradation within 60 min. It was found that the kinetic rate constant values were 0.008, 0.097, 0.050, and 0.040 min−1 for ZET0, ZET1, ZET2, and ZET3 NPs, respectively. Aside from their remarkable photocatalytic degradation efficiency, these ZET1 photocatalysts are highly stable even after five consecutive cycles. In addition, the active species test revealed that the primary oxidation species involved in the photocatalytic process are holes (h+) and hydroxyl radicals (•OH), and a possible photocatalytic mechanism for degrading RhB by ZET1 photocatalysts was tentatively proposed. The enhancement of the photocatalytic degradation efficiency is due to the low recombination rate of photogenerated charge carriers, as well as a strong synergistic impact of Tb, Er, and ZnO components. Thus, the current study could offer a versatile strategy for the design of new and effective nano photocatalysts for wastewater purification in the future.

Published: November 2024

AbstractRice straw bio waste was converted into a high‐performance adsorbent for Pb2+ ions removal by grafting it with methacrylic acid using microwave irradiation. For this purpose, six levels of poly(MAA)‐rice straw graft copolymers having different graft yields % with increasing order and designated as (PMAARSGC‐I to PMAARSGC‐VI) were prepared and characterized using FTIR, SEM, XRD, TGA, zeta potential and BET analysis. Different factors affecting the Pb2+ removal expressed as adsorption capacity such as pH, extent of grafting, treatment time, and lead ions concentrations were studied in detail. Various kinetics models (pseudo‐first‐order, pseudo‐second‐order, Elovich, and intraparticle diffusion), isothermal (Langmuir, Freundlich, Temkin, and Dubinin–Radushkevich) and thermodynamic studies have been applied. The results demonstrated that (a) FT‐IR, SEM, XRD, TGA, zeta potential, and BET analysis confirmed the formation of carboxyl groups onto the graft copolymer, (b) the adsorption capacity increased with increasing the Pb2+ concentration and extent of grafting within the range studied; pH from 1 to 6; and the adsorption time up to 60 min then leveled off afterward, (c) maximum adsorption capacity of poly(MAA)‐rice straw graft copolymer was found to be 118 mg/g at pH 6, 200 mg/L lead ions concentration, adsorption time, 60 min, and 0.1 g adsorbent, (d) the kinetic and isothermal studies revealed that the privilege of Elovich model and pseudo‐second‐order rate equation as well the Langmuir model with more R2 value. The calculated thermodynamic parameters indicated that the adsorption process was achievable, spontaneous, and exothermic at 298–318 K. Finally, the preliminary adsorption mechanism representing the interaction between the adsorbent and adsorbate has been projected.

AbstarctIn order to improve the curing rate, this study investigated the influence of various accelerators and their combinations on the curing behavior of epoxy resins. differential scanning calorimetry (DSC) was used to analyze the curing behavior of various accelerators in diglycidyl ether of the bisphenol A epoxy resin and the methyl hexahydrophthalic anhydride curing system, and activation energies were calculated using the Kissinger and Ozawa models. The results indicated a self‐catalytic characteristic in the curing process and showed that the activation energies for tris(dimethylaminomethyl)phenol (DMP‐30) and 1‐cyano‐2‐ethyl‐4‐methylimidazole (2E4MZ‐CN) were significantly lower compared to N,N‐dimethylbenzylamine, demonstrating higher curing reactivity. Furthermore, a novel strategy combining tertiary amine accelerator (DMP‐30) and imidazole accelerator (2E4MZ‐CN) was proposed and the activation energy variations with the degree of cure were analyzed employing the KAS method. When the mass ratio of DMP‐30 to 2E4MZ‐CN was 1:3, the activation energy was 59.08 kJ/mol, approximately 12% lower than using a single accelerator, which indicated the synergistic effects of the accelerators. Finally, the mechanism of synergistic effect of tertiary amine and imidazole accelerators on epoxy resin curing were proposed.

Authors: Liu Bing , Ma Baoji 
Published: November 2024

AbstractSilicone rubber is renowned for its excellent mechanical properties and high biocompatibility. 3D printing enables the realization of more complex structures and the development of more flexible and diverse functions, providing more opportunities and a more comprehensive range of applications in aerospace, biomedical, flexible wearable, soft robotics, and other fields. However, silicone rubber is often hindered by poor rheology and low curing efficiency, which significantly affects the forming performance of the parts. Therefore, this study introduces a UV‐follow curing method for direct ink writing (UFC‐DIW) utilizing UV‐curable silicone rubber. First, a kind of liquid silicone rubber (UV‐LSR) capable of rapid curing under UV light was synthesized, both its curing kinetics and rheological behavior were thoroughly investigated. Then, UV‐LSR inks with lower shear stress were printed using the UFC‐DIW method. A comparative analysis was conducted between the overall structure produced via UFC‐DIW and parts molded through postprinting integral curing methods. The results show that while parts cured postprinting exhibit deformation correlated with printing height, those fabricated using UFC‐DIW maintain structural integrity without deformation. It demonstrates that the UFC‐DIW method can effectively improve the formability of the parts.

AbstractChiral luminescent liquid crystal (LC) materials with switchable circularly polarized luminescence (CPL) signals have received extensive attention, in which the use of light stimulation to achieve different CPL states is of great significance. However, there are very few reports on the generation and regulation of CPL signals enabled by blue phase LC (BPLC). Herein, achieving CPL signal inversion based on the phase transition induced by light/temperature stimulation in a BPLC system with a wide room‐temperature window is reported. A binaphthalene azo‐based chiral photoswitch (S)‐switch 3 with high helical twisted power (HTP) and large HTP variation is synthesized, and a BP system with a wide room temperature range is further fabricated by doping (S)‐switch 3 and a fluorescence molecule into a bulk LC. By regulating the doping amount of (S)‐switch 3, a phase transition from BP to cholesteric (Ch) phase at room temperature is observed upon 365 nm UV light irradiation or during cooling process, and the polarization inversion of CPL signal is correspondingly found due to the different CPL generation mechanisms of BPLC and CLC. This study provides a new strategy for the flexible regulation of CPL signals in a BPLC system.

Published: November 2024

AbstractCarbon paper is widely utilized in supercapacitors primarily for its notable attributes, including high specific surface area, commendable electrical conductivity, and excellent chemical stability. Then investigate the effect of carbon paper with different porosities as supercapacitor substrates on the electrochemical performance of electrodes. Meanwhile, tungsten oxide is grown on the surface of carbon paper using the hydrothermal method to test the electrochemical performance of the composite electrode. The prepared carbon paper and oxygen‐deficient tungsten oxide (WOx) composite electrode (CP@WOx) exhibit an area‐specific capacitance of 915.8 mF/cm2 at a current density of 5 mA/cm2. In addition, the electrode exhibits good cycling stability. After 20,000 cycles, the capacitance remains 104.1 % of the original capacity at 50 mA/cm2 current density. Solid‐state symmetric supercapacitors assembled using CP@WOx electrode exhibit excellent performance in terms of surface energy density of 6.25 μWh/cm2 (at a power density of 0.6 mW/cm2) and maintain 100.4 % of their original capacity after 7000 charge/discharge cycles. Relying on the higher productivity advantage of centrifugal spinning technology over electrostatic spinning technology and other preparation processes, this study develops a new way of thinking for the large‐scale production of composite electrode materials, which has more considerable potential for large‐scale development.
Unleashing viral mimicry: A combinatorial strategy to enhance the efficacy of PARP7 inhibitors
Authors: Manetsch Patrick , Hottiger Michael O. 
Published: November 2024

AbstractCancer cells exploit mechanisms to evade immune detection triggered by aberrant self‐nucleic acids (NA). PARP7, a key player in this immune evasion strategy, has emerged as a potential target for cancer therapy. PARP7 inhibitors reactivate NA sensing, resulting in type I interferon (IFN) signaling, programmed cell death, anti‐tumor immunity, and tumor regression. Cancer cells with elevated IFN‐stimulated gene (ISG) scores, representing a viral mimicry‐primed state, are particularly sensitive to PARP7 inhibition. This review focuses on the endogenous sources of NA in cancer and the potential to exploit elevated aberrant self‐NA in cancer therapy. We describe strategies to increase cytoplamic NA levels, including targeting epigenetic control, DNA damage response, and mitochondrial function. We also discuss targeting RNA processing pathways, such as splicing and RNA editing, to enhance the immunostimulatory potential of existing NA. Combining PARP7 inhibitors with NA elevating strategies may improve cancer immunotherapy, especially for tumors with high ISG scores.

AbstractLanthanum phosphate is a well‐known potential host for rare earth activators for phosphor‐converted white LED application. Na+ and Bi3+ codoped Eu3+ activated LaPO4 nanophosphor is successfully synthesized using citrate‐based hydrothermal method at ambient condition and confirmed by XRD, EDS and XPS analysis. The excitation spectra of the sample exhibit sharp f‐f characteristics peak of Eu3+ at 393 nm that is found to be the most dominant. The comparative photoluminescence studies of La1‐xPO4:xEu3+(x = 0.10), La1‐x‐y PO4:xEu3+, yNa+(x = 0.10, y = 0.05), and La1‐x‐y‐zPO4:xEu3+, yNa+, zBi3+ (x = 0.10, y = z = 0.05) reveal a progressive enhancement of the orange emission from Eu3+ as Na+ and (Na+, Bi3+) ions are incorporated into the LaPO4 matrix. The dominance of 5D0‐7F1 magnetic dipole transition contributing a major part of orange luminescence of the nanophosphors and the symmetric site occupancy of Eu3+ was justified from the observed trend of in the Judd–Ofelt intensity parameters. The CIE studies confirm the improvement in color purity of emission from 32.5% to 90.6% due to the presence of Na+ and Bi3+ions.

AbstractBedaquiline (BDQ) is a drug used to treat multidrug‐resistant tuberculosis (MDR‐TB). It exhibits exposure‐dependent efficacy in eliminating Mycobacterium tuberculosis (Mtb). An easy, efficient and precise reverse‐phase ultrafast liquid chromatography (RP‐UFLC) method was developed to validate the free base of the antitubercular medication BDQ. BDQ was separated using a 10:90 v/v mobile phase of ammonium acetate buffer solution (pH = 5.4) and high‐performance liquid chromatography–grade methanol, with a flow rate of 1.5 mL/min and a UV detection wavelength of 226 nm. By using the Box–Behnken design (BBD) and response surface methodology (RSM), the method was optimised by varying critical analytical attributes (CAA) and critical performance attributes (CPAs) namely ammonium acetate fraction (%), flow rate (ml/min), buffer system molarity (M) and pH. BDQ was eluted at 7.5 min utilising isocratic elution. The method was linear in the concentration range of 0.5–300 μg/mL with limit of detection values of 0.039 μg/mL and limit of quantification of 0.12 μg/mL. The results indicate that this validated method can be used as an alternative method for assay of BDQ.

ABSTRACTObjectiveTo summarize and evaluate evidence pertaining to the clinical, genetic, histopathological, and neuroimaging correlates of cognitive and behavioral dysfunction in amyotrophic lateral sclerosis (ALS).MethodologyWe comprehensively reviewed the literature on cognitive and behavioral manifestations of ALS, narrating findings from both cross‐sectional and longitudinal studies. We discussed knowledge gaps in the evidence base and key limitations affecting studies to date, before formulating a framework for future research paradigms aimed at investigating clinicopathological correlates of neuropsychological dysfunction in ALS.ResultsStudies have demonstrated clinical associations with cognitive dysfunction in ALS e.g., bulbar‐onset of symptoms, pathological associations (extramotor TDP‐43 deposition), and imaging associations (frontotemporal involvement). The most common behavioral deficit, apathy, is highly associated with verbal fluency, but longitudinal studies assessing behavioral dysfunction in ALS are comparatively lacking.ConclusionLongitudinal studies have been helpful in identifying several potential correlates of cognitive and behavioral dysfunction but have frequently been confounded by selection bias and inappropriate testing platforms. This review provides a framework for more robust assessment of clinicopathological associations of neuropsychological abnormalities in ALS in the future, advocating for greater utilization of pre‐symptomatic C9orf72 repeat expansion‐carrying cohorts.

ABSTRACTBackgroundOne of the obstacles to seeking help for suicide is its social stigma. The literature suggests that suicide knowledge could impact this stigma. The present study aims to examine levels and predictors of suicide stigma and suicide literacy among Spanish‐speaking individuals from Spain and Latin America.MethodA total of 678 adults completed an online survey conducted from December 2021 to May 2022. The survey assessed sociodemographic and clinical variables, including the Literacy of Suicide Scale (LOSS‐SF) and Stigma of Suicide Scale (SOSS‐SF).ResultsResults showed the presence of stigmatization and a moderate level of suicide literacy. Latin Americans presented significantly more stigmatizing attitudes and lower levels of suicide literacy than Spaniards. Older age and stronger religious/spiritual beliefs were correlated with lower suicide literacy. Suicide stigma was regressed on lower suicide literacy, gender (men), stronger religious/spiritual beliefs, and lacking knowledge about how to find help. Furthermore, the region was significantly associated with the suicide glorification subscale, reporting Latin Americans' greater glorification.ConclusionsBy examining these factors, we aim to foster a deeper understanding of the attitudes and beliefs toward suicide. This understanding is crucial, as it may inform the development of effective interventions and prevention strategies that are culturally sensitive and tailored to diverse populations.

AbstractThe study was designed to provide an answer to the research question regarding the effect of digitalization on sustainability reporting and to reveal the mechanisms underlying this relationship. The methodology included data collection from 371 small‐ and medium‐sized enterprises (SMEs) originating from Ghana, by using a structured questionnaire. Further on, we employed the structural equation modeling (SEM) technique to analyze the relationships among our research variables. The findings showed that the effect of digitalization on SMEs' sustainability reporting is insignificant negative while sustainability competence fully mediated the relationship. The nexus between digitalization and sustainability competence was positively moderated by green knowledge integration. Similarly, stakeholder pressure was found to positively moderate the relationship between sustainability competence and sustainability reporting. To the best of our knowledge, this is the first study to approach digitalization's impact on sustainability disclosure in the Ghanaian SMEs' sector, resulting in manifold valuable policy and managerial practice implications.

Published: November 2024

ABSTRACTBackgroundThe sterol regulatory element‐binding protein (SREBP) pathway is essential for maintaining sterol homeostasis during B cell activation and germinal center B cell proliferation. However, its potential as a therapeutic target to treat B‐cell lymphoma remains unclear.MethodsWe examined SREBP protein expression in human B‐cell lymphoma samples using immunohistochemistry. Additionally, we conducted in vitro studies using SREBP signaling inhibitors in combination with rapamycin to assess their effects on cell proliferation and lipid metabolism in B‐cell lymphoma cells.ResultsOur analysis revealed high levels of SREBP2 protein expression in human B‐cell lymphoma samples. Inhibiting SREBP signaling or its downstream target HMG‐CoA reductase (HMGCR) with Fatostatin or Simvastatin effectively suppressed B‐cell lymphoma cell proliferation. However, B‐cell lymphoma cells responded to statin treatment by activating the mTORC1‐pS6 pathway, suggesting a compensatory mechanism to overcome statin‐induced cell cycle arrest. Combining low‐dose statin treatment with the mTOR inhibitor rapamycin produced a synergistic effect, significantly inhibiting B‐cell lymphoma proliferation, cell cycle progression, and lipid raft formation.ConclusionsThese results highlight the potential of a combined therapeutic approach targeting both SREBP and mTORC1 as a novel strategy for treating B‐cell lymphoma.
