AbstractTi3C2Tx Quantum dots (QDs)/L‐Ti3C2Tx fiber electrode (Q3M7) with high capacitance and excellent flexibility is prepared by a wet spinning method. The assembled units Ti3C2Tx nanosheets (NSs) with large size (denoted as L‐Ti3C2Tx) is obtained by natural sedimentation screen raw Ti3AlC2, etching, and mechanical delamination. The pillar agent Ti3C2Tx QDs is fabricated by an ultrasound method. Q3M7 fiber electrode gave a specific capacitance of 1560 F cm−3, with a capacity retention rate of 79% at 20 A cm−3, and excellent mechanical strength of 130 Mpa. A wide temperature all‐solid‐state the delaminated montmorillonite (F‐MMT)/Polyvinyl alcohol (PVA) dimethyl sulfoxide (DMSO) flexible hydrogel (DHGE) (F‐MMT/PVA DHGE) Q3M7 fiber supercapacitor is assembled by using Q3M7 fiber as electrodes and F‐MMT/PVA DHGE as electrolyte and separator. It showed a volume specific capacitance of 413 F cm−3 at 0.5 A cm−3, a capacity retention of 97% after 10 000 cycles, an energy density of 36.7 mWh cm−3 at a power density of 311 mW cm−3, and impressive capacitance and flexibility over a wide temperature range of −40 to 60 °C. This work provides an effective strategy for designing and assembling wide temperature all‐solid‐state fiber supercapacitors with optimal balance of capacitive performance and flexibility.

Published: December 2023

AbstractAchieving the selective modification of symmetric poly‐hydroxylated compounds presents a significant challenge due to the presence of identical active sites. Herein, we address this challenge through the design of a ternary catalytic system that includes a photoredox catalyst, a hydrogen atom transfer promotor and a carbonation catalyst. This catalytic system enables the reversible carbonation of acyclic polyols under CO2 atmosphere, which modulates the reactivity of its distinct C−H bonds toward hydrogen atom transfers. An exquisite selectivity for the monoalkylation is achieved in a variety of unprotected light polyols, yielding valuable building blocks in short reaction times. Mechanistic and computational studies demonstrate that the formation of an intramolecular hydrogen bond between the transient carbonate and the free alcohol is pivotal for the kinetic and thermodynamic activation of a specific alcohol.

AbstractSulfoxides are widely used in the pharmaceutical industry and as ligands in asymmetric catalysis. However, the efficient asymmetric synthesis of this structural motif remains limited. In this study, we disclosed a Ni‐catalyzed enantioconvergent reaction that utilizes both racemic allenyl carbonates and β‐sulfinyl esters. Our method employs cheap and more sustainable Ni(II) as a precatalyst and successfully overcomes the challenging poisoning effect and instability of sulfenate generated in situ. This enables the synthesis of a series of dienyl sulfoxides with enantioselectivity of up to 98 % ee. The product exhibits tremendous potential in various applications, including diastereoselective Diels–Alder reactions, coordination with transition metals, and incorporation into medicinal compounds, among others. Using a combination of experimental and computational methods, we have uncovered an interesting associated outersphere mechanism that contrasts with conventional mechanisms commonly observed in asymmetric transition metal catalysis.
Enhancement of the mechanical and tribological properties of carboxylated acrylonitrile butadiene rubber filled with cryptocrystalline graphite by different preparation methods

Published: December 2023

AbstractAs a cost‐effective and environmentally friendly natural mineral, cryptocrystalline graphite (CG) is applied in rubber materials and its performance has been evaluated. In this work, the filler dispersion and mechanical and tribological properties of carboxylated acrylonitrile butadiene rubber (XNBR)/CG composites by different preparation methods were studied. XNBR/CG composites prepared by latex blending (XNBR/CG‐L) exhibited better mechanical and tribological performance, higher toughness, and lower heat build‐up than those prepared by mechanical blending (XNBR/CG‐M). These differences were ascribed to the filler dispersion degree, filler amount and dispersed size, and also filler–rubber interfacial interaction. Adding CG was conducive to improving the stability of the friction coefficient and reduced the wear rate via the formation of graphite lubricant and transfer films. The tribological performance of XNBR/CG‐L was superior to that of XNBR/CG‐M because of the improved tensile strength, tear resistance, and toughness as well as lower temperature rise. Scanning electron microscopy (SEM) and optical microscope observation showed a smoother worn surface, less and smaller wear debris of XNBR/CG‐L, and a more uniform transfer film on the steel counterpart surface. The relevant results provided new insight into the performance and structural design of CG/rubber composites.

AbstractPolyester textiles have been applied in numerous industrial applications. Polyester fibers are characterized with being excellent insulators to electricity, having excellent flexural and impact strength, ease of manufacture, low‐cost, as well as having resistance to moisture and chemicals. However, polyester fibers cannot be stained due to the absence of active dyeing sites on the surface of the fibrous structure. Thus, polyester cannot be dyed after it has been extruded. Herein, we report the development of novel‐colored polyester fabrics using plasma‐assisted dyeing and anthocyanin natural probe for determination of ammonia that may cause severe harmful effects to human organs and even death. Anthocyanin was extracted from red cabbage and characterized. The water‐soluble anthocyanin was fastened to polyester fibers by mordant (potash alum) to generate anthocyanin–mordant coordinative complex nanoparticles. Polyester can be treated with thin layer of anthocyanin probe after activation with plasma. The results showed excellent colorfastness, ultraviolet blocking, and antibacterial performance of the anthocyanin‐dyed polyester (APET) fibers. The APET fibers showed great potential for developing a portable colorimetric device for an on‐site detection of ammonia. APET displayed a detection limit of aqueous ammonia in the range of 25–200 ppb, displaying a change in color from purple (542 nm) to white (387 nm).

AbstractDK‐GV‐04P, chemically identified as 3‐cinnamyl‐2‐(4‐methoxyphenyl) quinazolin‐4(3H)‐one, is an investigational molecule synthesized at the Chemical Biology Laboratory of the National Institute of Pharmaceutical Education and Research‐Ahmedabad. The compound has shown potential anticancer activity against squamous CAL27 cell lines. Metabolite identification and characterization are critical in drug discovery, providing key insights into a compound’s pharmacokinetics, pharmacodynamics safety, and metabolic fate. The primary aim of the study was to identify and characterize the in vitro metabolites of DK‐GV‐04P. In silico identification of the site of metabolism was also carried out using xenosite online software. The molecule was incubated with human liver microsomes and human S9 liver fraction to generate in vitro metabolites, which were further identified and characterized using ultra‐high‐performance liquid chromatography–quadrupole time of flight tandem mass spectrometry. A total of nine metabolites (four phase I and five phase II) were identified and characterized through tandem mass spectrometry. The major biotransformation pathways involved in metabolism of DK‐GV‐04P were hydroxylation, O‐demethylation and glucuronidation. In addition to this, a detailed biotransformation pathway of DK‐GV‐04P has been established in this study.

Published: December 2023

AbstractThis study examines how green human resource management (HRM) practices impact employees' subjective well‐being through the mediating mechanism of employees' green behavior (EGB). We further explore the moderating role of resource commitment. Based on a sample of 249 employees and their supervisors working in small‐ to medium‐sized enterprises (SMEs) in Ghana, we discovered that green HRM practices have a positive influence on EGB, and this connection is further reinforced by resource commitment. The analysis also reveals that EGB serves as a mediator in the relationship between green HRM practices and employees' subjective well‐being. These findings suggest that green HRM practices affect employees' subjective well‐being through EGB. The wider implications of these findings for theory and HRM practitioners are discussed.

AbstractBackgroundConnective tissue graft substitutes have been used widely to overcome autogenous graft limitations. Nevertheless, they do not provide comparable results in the treatment of periodontal and peri‐implant soft tissue defects. Based on the principles of tissue‐engineered materials, injectable platelet‐rich fibrin (i‐PRF) has been combined with collagen matrices (CMs) to enhance their clinical efficacy. To the best of our knowledge, this is the first case series demonstrating the use of i‐PRF for the biofunctionalization of a volume‐stable collagen matrix (VCMX) as an adjunct to coronally advanced flap (CAF) to treat single gingival recession (GR) defects.Methods & ResultsThe study included 10 patients. Bleeding on probing, probing depth, GR height, clinical attachment level, esthetics, and dentin hypersensitivity were evaluated. After 6 months, a significant GR reduction (RecRed: 2.15 ± 0.7 mm; p = 0.005) and percentage of root coverage (% RC) of 81.13% were observed. Additionally, 40% of the sites showed complete root coverage. Gingival thickness increased 0.64 mm. Patient‐centered evaluations demonstrated dentin hypersensitivity and esthetics improvements by the end of follow‐up.ConclusionVCMX biofunctionalized with i‐PRF associated with CAF technique showed promising clinical outcomes in the treatment of single RT1 GR defects.

Published: December 2023

AbstractCatalytic conversion of light alkanes (C1‐C3) to aromatics offers an attractive valorization route for abundant gas resources and has been a prevalent topic of research over the past few decades. Despite considerable advancements in the understanding of these reactions, several fundamental and practical hurdles have prevented their industrial application. Among the numerous attempts to resolve these issues, co‐feeding certain additives yields promising results, including the activation of alkanes under milder conditions, an increase in catalytic stability, and a shift in product distribution towards more desirable compounds. Systematic studies have elucidated the precise working mechanism of the co‐feeds in aromatization systems, explaining the experimentally observed results. This review provides an extensive compilation of information on the application of co‐feeds in light alkane aromatization, which has accumulated in the literature since the pioneering reports in the 1990s. Detailed summaries are provided for each additive, ranging from hydrocarbons to oxidants. Viable strategies for future work in this field, aiming to bridge the gap between academic studies and industrial applications, are also discussed.
Investigations on The Effect of Cd Dopant on The Properties of 2D Nanostructured Vanadium Oxide Thin Films
Authors: Rajan Niju , Manjunatha D. V. 
Published: December 2023

AbstractThe structural, morphologic, and photosensitive characteristics of pure and Cd‐doped V2O5 thin films grown by spray pyrolysis are investigated in this work. To stabilize the precursor, glycine is added during preparation. The choice of Cadmium (Cd) as a dopant is made with Vanadium's ionic radius compatibility in consideration. X‐ray Diffraction (XRD) measurements show that the orthorhombic structure does not alter with the addition of Cd dopant. The morphological studies reveal that the surface roughness of synthesized V2O5 increases with dopant concentration. Investigation of field emission scanning electron microscope (FESEM) images indicate that as the dopant concentration increases, the produced film's particle size reduces and hence It is suitable for gas sensing applications. UV–vis spectroscopy is employed to investigate the influence of doping on the absorbance, transmittance, and optical energy gap of the deposited thin film. The material can be taken into account for photovoltaic applications, as the investigations demonstrate an improved transmittance rate, lower absorption rate, and an increase in the optical bandgap in the visible spectra.

Published: December 2023

SummaryThis article presents an improved least mean square (LMS) algorithm‐based control approach for a three‐phase grid interfaced solar photovoltaic (GISPV) system for smart building applications. The SPV is primarily utilized to supply household loads, and the absence or intermittency of SPV is curbed by utilizing power from the grid. The majority of household loads are nonlinear loads that affect the grid power quality (PQ). However, the effects of both linear and nonlinear loads on grid PQ have been analyzed in this article. This article proposes a Gaussian Kernel function‐based normalized LMS (GKNLMS) algorithm to calculate the active peak weight component of the load current, thereby utilizing it to obtain a sinusoidal reference current. Considering a higher step size and utilizing the Gaussian Kernel function for reduced mean square error (MSE) improves both the convergence rate and accuracy of estimation in the conventional LMS. The proposed control technique effectively addresses system anomalies caused by dynamic solar irradiance, load variation, and unbalanced loading conditions. Furthermore, the system response with the GKNLMS algorithm is assessed in MATLAB/Simulink and validated by developing a laboratory setup of the system for experimentation.

AbstractCOVID‐19 is a systemic inflammatory disease initiated by SARS‐CoV‐2 virus infection. Multiple vaccines against the Wuhan variant of SARS‐CoV‐2 have been developed including a whole virion beta‐propiolactone‐inactivated vaccine based on the B.1.1 strain (CoviVac). Since most of the population has been vaccinated by targeting the original or early variants of SARS‐CoV‐2, the emergence of novel mutant variants raises concern over possible evasion of vaccine‐induced immune responses. Here, we report on the mechanism of protection by CoviVac, a whole virion‐based vaccine, against the Omicron variant. CoviVac‐immunized K18‐hACE2 Tg mice were protected against both prototype B.1.1 and BA.1‐like (Omicron) variants. Subsequently, vaccinated K18‐hACE2 Tg mice rapidly cleared the infection via cross‐reactive T‐cell responses and cross‐reactive, non‐neutralizing antibodies recognizing the Omicron variant Spike protein. Thus, our data indicate that efficient protection from SARS‐CoV‐2 variants can be achieved by the orchestrated action of cross‐reactive T cells and non‐neutralizing antibodies.

AbstractThe complex {Na2(H2O)8[GdCu5(GlyHA)5(H2O)4L]2}L2 ⋅ 2.5DMF ⋅ 10.5H2O (1, where GlyHA2−= glycinehydroxamate, L2−= 4,4′‐bis(2‐sulfonatostyryl)biphenyl) was obtained as the outcome of the metathesis reaction of previously reported [GdCu5(GlyHA)5(CO3)(NO3)(H2O)5] ⋅ 3.5H2O with an excess of the disulfonate‘s sodium salt. X‐Ray analysis of1shows a dimeric structure in which 15‐metallacrown‐5 units {GdCu5}3+are arranged in an “edge‐to‐edge” manner by way of two linking disulfonates, L2−. Magnetic studies of polycrystalline1over a temperature range of 2–300 K revealed both Gd‐Cu ferromagnetic and Cu‐Cu antiferromagnetic interactions within the metallacrown unit. ExperimentalχMT vs. Tdata for1were fitted using different theoretical models. A two‐Jmodel, which takes into account both exchange interactions between adjacent copper(II) ions and the Gd‐Cu exchange interactions allows fitting of theχMT vs. Tdata in the whole temperature range. The values obtained for the exchange parameters are in accord with previously reported parameters for Ln(III)‐Cu(II) 15‐metallacrowns‐5. The 240 GHz powder EPR spectra for1were recorded between 30 and 150 K.

AbstractThe dimer of dipiperidinoacetylene, 1,3,4,4‐tetrapiperidino‐3‐buten‐1‐yne, reacts with [IrCl(COD)]2 (COD=1,5‐cyclooctadiene) to give the corresponding 1,3,4,4‐tetrapiperidino‐1,2‐cyclobutadiene‐iridium complex [(CBA)IrCl(COD)] with a four‐membered cyclic bent allene (CBA) ligand. Reaction with carbon monoxide affords the dicarbonyl complex cis‐[(CBA)IrCl(CO)2], which exhibits low CO stretching frequencies and an associated Tolman electronic parameter (TEP) value of 2030 cm−1, which is lower than any other TEP value reported for cyclic carbene and carbenoid ligand systems. Treatment of [(CBA)IrCl(COD)] with sodium tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate (NaBARF) followed by addition of phosphines or pyridine (py) yields the cationic complexes [(CBA)IrL(COD)][BARF] (L=PPh3, PPh2Me, PPhMe2, PCy3, py) as potential hydrogen isotope exchange (HIE) catalysts. DFT calculations provide evidence for a suitable pathway for the cyclization of 1,3,4,4‐tetrapiperidino‐3‐buten‐1‐yne at transition metal complex fragments, here AuCl, IrCl(COD), and IrCl(CO)2, as a general route to four‐membered CBA metal complexes.

Published: December 2023

AbstractIntroductionDespite the important impact of sexual violence (SV) on mental health, few victims disclose their experiences. Although research in adult victims suggests that SV disclosure could protect against long‐term mental health problems, studies in older adults are lacking.ObjectivesTo establish the prevalence of depression, anxiety, posttraumatic stress disorder (PTSD), suicide attempts, and self‐harm, their association with SV disclosure, and the moderating effect of sociodemographic characteristics and SV framing in the relation between SV disclosure and the different mental health outcomes in older SV victims.MethodsData on sexual victimisation, mental health, SV framing, and disclosure were collected through structured face‐to‐face interviews with 171 randomly selected sexually victimised adults of 70 years and older living in Belgium. SV was measured using behaviourally specific questions based on a broad definition. Mental health outcomes were measured using validated scales.ResultsDepression, anxiety and PTSD were reported by 34%, 33% and 9% of participants respectively, 5% had attempted suicide and 1% reported self‐harm during lifetime. SV framing was associated with the kind of help victims consulted. SV disclosure was not linked with depression and anxiety, but was associated with an increase of PTSD symptoms in older victims with care dependency (p = 0.004) or a chronic illness and/or disability (p = 0.025).ConclusionsSV disclosure in itself does not protect against adverse mental health outcomes in old age. Capacity building of professionals trough training and development of clinical guidelines and care procedures may increase appropriate response to SV disclosure by older victims.
