Published: October 2023

AbstractThe construction of platinum (Pt) atomic layers is an effective strategy to improve the utilization efficiency of Pt atoms in electrocatalysis, thus is important for reducing the capital costs of a wide range of energy storage and conversion devices. However, the substrates used to grow Pt atomic layers are largely limited to noble metals and their alloys, which is not conducive to reducing catalyst costs. Herein, low‐cost chromium nitride (CrN) is utilized as a support for the loading of epitaxial ultrathin Pt atomic layers via a simple thermal ammonolysis method. Owing to the strong anchoring and electronic regulation of Pt atomic layers by CrN, the obtained Pt atomic layers catalyst (containing electron‐deficient Pt sites) exhibits excellent activity and endurance for the formic acid oxidation reaction, with a mass activity of 5.17 A mgPt−1 that is 13.6 times higher than that of commercial Pt/C catalyst. This novel strategy demonstrates that CrN can replace noble metals as a low‐cost substrate for constructing Pt atomic layers catalysts.

AbstractUltrafast charge carrier dynamics of green‐light emitting InP/ZnSe/ZnS core–shell quantum dots (QDs) with three different ZnSe thickness of 2.0 nm (gQD‐20), 2.4 nm (gQD‐24), or 3.3 nm (gQD‐33) are interrogated by femtosecond transient absorption (TA) and femtosecond stimulated Raman spectroscopy (FSRS). Auger‐type cooling of hot electron into the band‐edge level of InP is clearly manifested in the TA spectra, giving its time constant of ≈222, 300, or 349 fs for gQD‐20, gQD‐24, or gQD‐33, respectively, indicating that the state‐filling to the 1S(e) of InP is significantly slowed down with the increase of the mid shell thickness. The global analysis of the whole TA spectra turns out to be extremely useful to explain the dynamic behavior of the heterogeneous ensemble of single and/or bi‐ (or multi‐) excitons in the presence of the Stark‐shift. The hole‐relaxation dynamics into the band‐edge 1S (h) of the core InP is revealed in the bleaching dynamics of the FSR bands corresponding to the phonon mode of InP or ZnSe, giving the estimated lifetime of 1.0–1.4 ps for gQD‐20. The hole‐relaxation dynamics by the phonon emission seem to be little sensitive to the ZnSe shell thickness.

AbstractThe metal‐mediated exfoliation (MME) method enables monolayer‐selective exfoliation of van der Waals (vdW) crystals, improving the efficacy of large monolayer production. Previous physical models explaining monolayer‐selective MME propose that the main contributors to monolayer‐selectivity are vdW crystal/metal surface binding energy and/or vdW crystal layer strain resulting from lattice mismatch. However, the performance of some metals for MME is inconsistent with these models. Here, a new model is proposed using MoS2 as a representative vdW crystal. The model explains how the MoS2/metal interface electrostatics, in combination with strain, determines monolayer‐selectivity of MME by modulating the MoS2 interlayer energy. Monolayer MoS2/metal interfaces are characterized using in situ Raman spectroscopy and density functional theory calculations to estimate the electrostatics and strain of MoS2 in contact with different metals. The model successfully demonstrates the dependence of MME monolayer‐selectivity on the MoS2/metal interface electrostatics and highlights the significance of electrostatics in nanomaterial vdW interactions.

Published: October 2023

Abstract2D transitional metal dichalcogenide (TMDC) materials have shown great potential in the optoelectronics and electronics field owing to their unique and favorable properties. However, developing high‐performance broadband photodetectors in bare TMDC material is impeded due to their limited absorption and poor charge‐carrier separation. The recent advancement in van der Waals heterostructure fabrication has exhibited a new path to improve the device performance. In the present work, a facile approach is presented to fabricate a large area of PtS2/MoS2 heterostructure, which demonstrates a broad spectral detection range from 400 to 1200 nm with high responsivity (30.2 A W−1) and detectivity (1.12 × 1013 Jones) even under near‐infrared (NIR) 900 nm light illumination at moderate bias. Moreover, the PtS2/MoS2 photodetector exhibits a much enhanced responsivity (97 times) and detectivity (33 times) compared with bare MoS2. A rise/fall time of 11 ms/10 ms for the PtS2/MoS2 device represents its fast response speed. The X‐ray photoelectron spectroscopy measurements reveal the type‐I band alignment between the PtS2 and MoS2, which are further utilized to understand the charge carrier dynamics between the PtS2 and MoS2 interface. This work presents a simple strategy to synthesize scalable, high‐performance broadband photodetectors for future optoelectronics applications.

AbstractAquaculture developmental plans represent a nation's determination for self‐reliance on domestic fish production through resilient aquaculture. This study reviewed the 2012 Ghana National Aquaculture Development Plan (GNADP) and sought inputs from industry stakeholders to inform GNADP 2023 using the ecosystem approach to aquaculture (EAA). In furtherance of this, we also investigated the justifications for antibiotic treatments including the assessment of the sector that is supposed to regulate aquaculture growth. The findings suggest that GNADP 2023 must be strategized to address industry sustainability bottlenecks identified as input availability and quality, permitting, regulation and enforcement, financing schemes and technical expertise. In terms of technical expertise, the inclusion of women in aquaculture can diversify the skill sets for the improvement of capacity and competence in good aquaculture practices and fish health management. Sector partnerships can aid in leveraging the expertise and resources among sectors to address persistent industry issues. The justifications for antibiotic treatments are disease management, prophylactics, antibiotic availability, application, and effectiveness, capacity and competence, including regulation and enforcement. This also comprised the sense of ownership and responsibility as farmers feel they must safeguard their investment. It is therefore important for farmers to pursue preventative aquaculture biosecurity measures. The government sector was selected predominantly to regulate aquaculture growth. We however recommended a participatory approach as this could facilitate peer regulation to enhance the regulation and enforcement of aquaculture regulations. The findings in this study are worth considering as it pioneers the adoption of the EAA framework for aquaculture developmental planning in Ghana.

AbstractThe sodium‐rich antiperovskites (NaRAPs) with composition Na3OB (B=Br, Cl, I, BH4, etc.) are a family of materials that has recently attracted great interest for application as solid electrolytes in sodium metal batteries. Non‐Arrhenius ionic conductivities have been reported for these materials, the origin of which is poorly understood. In this work, we combined temperature‐resolved bulk and local characterisation methods to gain an insight into the origin of this unusual behaviour using Na3OBr as a model system. We first excluded crystallographic disorder on the anion sites as the cause of the change in activation energy; then identified the presence of a poorly crystalline impurities, not detectable by XRD, and elucidated their effect on ionic conductivity. These findings improve understanding of the processing‐structure‐properties relationships pertaining to NaRAPs and highlight the need to determine these relationships in other materials systems, which will accelerate the development of high‐performance solid electrolytes.

Published: October 2023

AbstractSelf‐healing coatings can restore their performance after inevitable damage and are promising in the industry owing to their longer service life and lower repair cost. The use of Diels–Alder reaction bonds is well‐known to generate thermally self‐healing coatings. In this study, a series of cross‐linked self‐healing polyurethane (PU) coatings were synthesized through Diels–Alder reactions of p‐tert‐butyl calix[4]arene bearing furan groups (C4A‐FA) as a new chain extender and a bismaleimide (BMI) polyether amine as a Diels–Alder cross‐linking agent. Adding C4A‐FA to PUs improves their mechanical properties, thermal stability, and self‐healing ability. Additionally, these modifications can result in the formation of composite networks with PU that exhibit thermoreversibility and self‐healing properties. These changes have led to PUs containing modified calix[4]arene (C4A‐FA) having better properties compared with unmodified calix[4]arene PUs. The properties of prepared coatings were evaluated by Fourier transform infrared spectroscopy, scanning electron microscope, differential scanning calorimetry (DSC), thermogravimetric analyses (TGA), and tensile tests compared with a typical PU sample. The tensile and TGA results show an improvement in the thermal and mechanical properties of the polymers by increasing the C4A‐FA content. By replacing 15% of butandiol (BDO) with C4A‐FA in PU pure, the tensile strength increased from 1.69 to 5.14 MPa. Furthermore, adding diels–alder (DA) bonds enhanced the tensile strength to 10.49 MPa for PU‐C4A15‐DA. According to DSC results, a broad endothermic peak from nearly 80–140°C confirmed the retro‐DA reactions in the synthesized thermoreversible samples. The healing efficiency of the PU‐C4A15‐DA sample was obtained at 92.5% (measured by tensile test), which is the highest value among cross‐linked self‐healing PUs reported in the literature.

AbstractBackground/AimsNatural and synthetic biocompatible polymers have received significant attention in the pharmaceutical industry due to their rapid and effective healing properties in the wound healing process. The aim of this study was to optimize the extraction of onions, the preparation of sodium alginate/collagen/hydrogen boron nitride (NaAlg/Col/h‐BN) membranes using the Box‐Behnken experimental design, and determine the optimal conditions for quercetin release. The study also aimed to investigate the antimicrobial and antioxidant activities of the prepared membranes and their therapeutic properties.Methods and ResultsThe prepared membranes were characterized by scanning electron microscopy (SEM), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), and X‐ray diffraction (XRD). Antimicrobial activities were tested against Gram‐negative (Gr‐) Escherichia coli ATCC 25922, Klebsiella pneumonia, Enterobacter aerogenes, Gram‐positive (Gr+) Staphylococcus aureus ATCC 25923, and Candida albicans ATCC 10231 pathogens. In vitro release studies were conducted to examine the therapeutic properties of the prepared membranes. The optimum conditions for the extraction of onions and the preparation of NaAlg/Col/h‐BN membranes were found to be EtOH = 75 mL, t = 2 h, T = 45°C, and NaAlg = 1.0 g, Col = 2.0 g, and h‐BN = 6% wt, respectively. The prepared membranes exhibited serious antimicrobial properties against S. aureus and C. albicans. The membranes also promoted the controlled release of quercetin for 24 h in vitro, indicating their potential as a new approach in wound treatment.ConclusionThe study concludes that quercetin‐filled NaAlg/Col/h‐BN membranes have promising therapeutic properties for wound healing. The membranes exhibited significant antimicrobial and antioxidant properties, and their controlled release of quercetin suggests their potential for use in wound healing applications.

Published: October 2023

AbstractBackgroundDespite technological advances ensuring stable cell culture perfusion operation over prolonged time, reaching a cellular steady‐state metabolism remains a challenge for certain manufacturing cell lines. This study investigated the stabilization of a steady‐state perfusion process producing a bispecific antibody with drifting product quality attributes, caused by shifting metabolic activity in the cell culture.Main methodsA novel on‐demand pyruvate feeding strategy was developed, leveraging lactate as an indicator for tricarboxylic acid (TCA) cycle saturation. Real‐time lactate monitoring was achieved through in‐line Raman spectroscopy, enabling accurate control at predefined target setpoints.Major resultsThe implemented feedback control strategy resulted in a three‐fold reduction of ammonium accumulation and stabilized product quality profiles. Stable and flat glycosylation profiles were achieved with standard deviations below 0.2% for high mannose and fucosylation. Whereas galactosylation and sialylation were stabilized in a similar manner, varying lactate setpoints might allow for fine‐tuning of these glycan forms.ImplicationThe Raman‐controlled pyruvate feeding strategy represents a valuable tool for continuous manufacturing, stabilizing metabolic activity, and preventing product quality drifting in perfusion cell cultures. Additionally, this approach effectively reduced high mannose, helping to mitigate increases associated with process intensification, such as extended culture durations or elevated culture densities.

Published: October 2023

AbstractIntroductionEarly palliative care (EPC) has been advocated to improve cancer patients' health. However, EPC differs with regard to its elements and target groups. It is not known which parts of EPC contribute to effectiveness for which patient group. This scoping review provides a structured analysis of EPC interventions and outcome measures.DesignWe searched EMBASE, MEDLINE, CINAHL, and CENTRAL up to February 2022. We included randomized controlled trials (RCT), nonrandomized trials, cohort studies (CS), and controlled before‐after studies of EPC in adult patients in English, Dutch, and German language. Interventions had to be self‐labeled as EPC. Screening and data extraction were performed by two raters. A structured analysis incorporating the TIDieR checklist was performed to describe the elements of the interventions.ResultsWe screened 2651 articles, resulting in 40 articles being included: 34 studies were RCT and six studies were CS with a mean sample size of 208 patients. Patients with pancreatic (n = 10) and lung cancer (n = 9) were most often included. Studies reported different reference points for the onset of EPC such as time after diagnosis of incurable cancer (n = 18) or prognosis (n = 9). Thirteen studies provided information about elements of EPC and eight studies about the control intervention. Most frequent elements of EPC were symptom management (n = 28), case management (n = 16), and advance care planning (ACP; n = 15). Most frequently reported outcome measures were health‐related quality of life (n = 26), symptom intensity (n = 6), resource use, and the patient's mood (n = 4 each).ConclusionThe elicited heterogeneity of ECP in combination with deficits of reporting are considerable barriers that should be addressed to further develop effective EPC interventions for different groups of cancer patients.
The influence of brand innovativeness on consumer purchase intentions towards domestic global brands in emerging markets: Evidence from China
Authors: Chen Jun , Liang Mo , Wei Ye 
Published: October 2023

AbstractThere has been a growing trend of supporting domestic brands following the COVID‐19 pandemic, and some brands from emerging markets have accelerated their internationalisation over the past few years. This article investigates the influence of brand innovativeness on Chinese consumers' brand attitudes and purchase intentions towards domestic global brands in the digital device industry. A total of 220 undergraduate students from China took part in the survey. Confirmatory factor analysis and path analysis were used to test the hypotheses using structural equation modelling. The results showed that brand innovativeness stimulates purchase intentions through the mediation of perceived brand globalness (PBG) and perceived brand localness (PBL). In addition, consumer ethnocentrism moderates the relationship between PBL and brand attitudes. The theoretical and practical implications are discussed herein.
Simulating the Moisture Diffusion and Evaporation of Sawdust during Convective Drying using the Spatial Reaction Engineering Approach
Authors: Shin Woo In , Foo Jia Wei , Putranto Aditya , Hii Ching Lik 
Published: October 2023

AbstractThe spatial reaction engineering approach (S‐REA) was used to simulate hot air drying of sawdust. The studies extended the previous work reported in literature where the sawdusts were dried using hot air at 70 °C, 80 °C, and 90 °C. The simulated results were found to agree well with the experimental moisture content (R2 > 0.98) and temperature (R2 > 0.82) profiles. In a further analysis using S‐REA, the spatial profiles of moisture content and vapor concentration were generated to understand better the physics behind. Simulation also revealed that the external mass transfer resistance was more dominant as compared to the internal diffusion resistance. The vapor concentrations were observed peaked at time range of about 10 800– 18 000 s and dropped thereafter upon further heating. This observation could be supported by the variation in the vapor effective diffusivities where peak diffusivity values typically occur after most of the moisture evaporates towards the end of drying.

AbstractThe architecture of lithium‐sulfur (Li‐S) batteries can hold five times more charge capacity compared to Li‐ion batteries. This review emphasizes the recent research findings on the desired loading of sulfur, the electrolyte‐to‐sulfur ratio, and a detailed view of the polysulfide shuttling effect. Problems with electrolyte stability are also discussed as well as the potential remedies they provided in various systems, as Li‐S batteries have great potential to surmount these critical issues by understanding the mechanism. Future scopes of Li‐S batteries can be progressively attained by optimizing the pore structure, designing highly conductive and strong sulfur confinement systems, and thereby pairing with anode materials to explore the possibility of innovative components for commercializing Li‐S batteries.

AbstractBlood continually contributes to the maintenance of homeostasis of the body and contains information regarding the health state of an individual. However, current hematological analyses predominantly rely on a limited number of CD markers and morphological analysis. In this work, differentially sensitive fluorescent compounds based on TCF scaffolds are introduced that are designed for fluorescent phenotyping of blood. Depending on their structures, TCF compounds displayed varied responses to reactive oxygen species, biothiols, redox‐related biomolecules, and hemoglobin, which are the primary influential factors within blood. Contrary to conventional CD marker‐based analysis, this unbiased fluorescent phenotyping method produces diverse fingerprints of the health state. Precise discrimination of blood samples from 37 mice was demonstrated based on their developmental stages, ranging from 10 to 19 weeks of age. Additionally, this fluorescent phenotyping method enabled the differentiation between drugs with distinct targets, serving as a simple yet potent tool for pharmacological analysis to understand the mode of action of various drugs.

Published: October 2023

AbstractIn the last decade, magnesium complexes have emerged as a viable alternative to transition‐metal catalysts for the hydrofunctionalization of unsaturated bonds. However, their potential for advanced catalytic reactions has not been thoroughly investigated. To address this gap, we have developed a novel magnesium amide compound (3) using a PNP framework that is both bulky and flexible. Our research demonstrates that compound 3 can effectively catalyze the synthesis of biologically significant oxazolidinone derivatives. This synthesis involves a tandem reaction of hydroalkoxylation and cyclohydroamination of isocyanate using propargyl alcohol. Furthermore, we conducted comprehensive theoretical calculations to gain insights into the reaction mechanism. It is important to note that these types of transformations have not been reported for magnesium and would significantly enhance the catalytic portfolio of the 7th most abundant element.
