Published: March 2022

AbstractPnictides are superior infrared (IR) nonlinear optical (NLO) material candidates, but the exploration of NLO pnictides is still tardy due to lack of rational material design strategies. An in‐depth understanding structure–performance relationship is urgent for designing novel and eminent pnictide NLO materials. Herein, this work unravels a vital band gap mechanism of pnictides, namely P atom with low coordination numbers (2 CN) will cause the decrease of band gap due to the delocalization of non‐bonding electron pairs. Accordingly, a general design paradigm for NLO pnictides, ionicity–covalency–metallicity regulation is proposed for designing wide‐band gap NLO pnictides with maintained SHG effect. Driven by this idea, millimeter‐level crystals of MgSiP2 are synthesized with a wide band gap (2.34 eV), a strong NLO performance (3.5 x AgGaS2), and a wide IR transparency range (0.53–10.3 µm). This work provides an essential guidance for the future design and synthesis of NLO pnictides, and also opens a new perspective at Zintl chemistry important for other material fields.

AbstractThe adoption of 2D transition metal dichalcogenide (TMD) based optoelectronic devices is limited by Fermi level pinning effects and consequent large contact resistances upon contacting TMDs with bulk metal electrodes. A potential solution for near‐ideal Schottky–Mott behavior and concomitant Schottky barrier height control is proposed by contacting TMDs and (semi‐)metals in van der Waals heterostructures. However, measurement approaches to directly assess interface parameters relevant to the Schottky–Mott rule on a local scale are still lacking. In the present work, a heterostructure of monolayer tungsten diselenide (WSe2) with monolayer graphene (1LG) and bilayer graphene (2LG) is investigated on a bottom‐gate substrate. Kelvin probe force microscopy and tip‐enhanced photoluminescence measurements at different electrostatic doping induced Fermi levels in graphene enable decoupling and quantification of contributions from the interface dipole and electrode work function. These are used to locally probe Schottky barrier characteristics with below 32 nm lateral resolution, demonstrating that the WSe2/1LG junction operates at the Schottky–Mott limit (S ≈ 1). At the WSe2/2LG junction, a reduction of the interface dipole is directly related to changes in excitonic emission properties. These are attributed to charge transfer modulation across the interface, critical for obtaining high‐performance transfer characteristics in transistors and related devices.
Latent vector autoregressive modeling and feature analysis of high dimensional and noisy data from dynamic systems
Authors: Qin S. Joe 
Published: March 2022

AbstractIn this article, a novel latent vector autoregressive (LaVAR) modeling algorithm with a canonical correlation analysis (CCA) objective is proposed to estimate a fully‐interacting reduced‐dimensional dynamic model. This algorithm is an advancement of the dynamic inner canonical correlation analysis (DiCCA) algorithm, which builds univariate latent autoregressive models that are noninteracting. The dynamic latent variable scores of the proposed algorithm are guaranteed to be orthogonal with a descending order of predictability, retaining the properties of DiCCA. Further, the LaVAR‐CCA algorithm solves multiple latent variables simultaneously with a statistical interpretation of the profile likelihood. The Lorenz oscillator with noisy measurements and an application case study on an industrial dataset are used to illustrate the superiority of the proposed algorithm. The reduced‐dimensional latent dynamic model has numerous potential applications for prediction, feature analysis, and diagnosis of systems with rich measurements.
Efficient Recycling of Catalyst‐Solvent Couples from Lewis Acid‐Catalyzed Asymmetric Reactions in Water

Published: March 2022

AbstractBioinspired supramolecular architectures were used to compartmentalize highly charged aqua scandium ions into chiral hydrophobic scaffolds for Lewis acid‐catalyzed asymmetric reactions. Recycling without significant loss in catalytic performance is a formidable task, especially for Lewis acid‐catalyzed reactions. This is because Lewis basic impurities derived from starting materials, products, and water are highly competitive ligands for both substrate binding and metal complexation, thus poisoning the Lewis acids and leading to their leaching. Even when basic aniline is used, the architecture allowed for effective suppression of Sc3+ leaching and for reuse of solvent‐catalyst couples in asymmetric ring‐opening reactions without deactivation. Application to asymmetric thia‐Michael addition and hydroxymethylation was also demonstrated. The successful recycling in highly Lewis basic environments underpins the exceptionally high robustness of the chiral Lewis acid catalyst.

AbstractThe present study aims at developing and characterizing gum odina ‐ sodium alginate based microsphere as a carrier for capecitabine. Microspheres with varying concentration of polymers (gum odina and sodium alginate) were formulated using calcium chloride as a cross‐linker by ionotropic gelation technique. The formulated microspheres were optimized by entrapment efficiency, drug yield, particle size, swelling index, and in vitro drug release study. The optimized microsphere (F6) was characterized in terms of SEM, AFM, FTIR, XRD, degradation study, moisture content study, and antioxidant activity. The F6 was spherical in shape with a mean diameter of 568.33 ± 45.76 μm and drug entrapment efficiency of 45.91 ± 2.94%. In vitro dissolution study of optimized formulation exhibited negligible released in 0.1 N HCl (pH 1.2) and followed by 100% release in phosphate buffer (pH 7.4) within 24 h. In vitro cytotoxicity assay (MTT) of formulation F6 on HT29 human colon cancer cell line indicated inhibition of the proliferation of tumor cell over a longer period of time. The overall experiment indicated that capecitabine loaded natural polymers based formulated microsphere could be a promising approach for the prevention of colon cancer.
Cosmological constraints on bulk viscous f(Q,T) gravity
Authors: Sokoliuk Oleksii , Baransky Alexander 
Published: March 2022

AbstractIn the General Theory of Relativity (GR) gravitational interactions are described by the scalar Ricci curvature. But there exists another class of modified gravity theories equivalent to GR, described by the torsion tensor or non‐metricity scalar. One of such theories, investigated in this paper is gravity, built from the arbitrary function of non‐metricity scalar non‐minimally coupled to the trace of stress‐energy tensor. Current work is aimed on the linear gravity, where and are free MOG parameters to be varied. As well, we assume that the fluid is bulk‐viscous with pressure and the bulk viscosity parameter . From the modified Einstein Field Equations (EFE's) we obtain the Hubble parameter analytically and constrain free parameters of the model through the MCMC sampling of 57 recent Hubble parameter observations. We found that computed Hubble rate for our model from MCMC sampling converges with the observational data at the confidence level. To examine the current accelerated expansion rate of the universe in details we use the statefinder diagnostics. Besides, to distinguish CDM and our model we use analysis.
A further study of relations between motor impairment and social communication, cognitive, language, functional impairments, and repetitive behavior severity in children with ASD using the SPARK study dataset

Published: March 2022

AbstractMotor impairments are pervasive and persistent in children with autism spectrum disorder (ASD) throughout childhood and adolescence. Based on recent studies examining motor impairments in children with ASD between 5 and 15 years (i.e., SPARK study sample), 87–88% of this population is at‐risk for a motor impairment, these problems persisted until 15 years, and related to their core (social communication skills and repetitive behaviors [RBs]) and comorbid (language, cognitive, and functional) impairments. Persistent motor impairments extending into adolescence/adulthood could negatively impact their independent daily living skills, physical fitness/activity levels, and physical/mental health. While multiple studies have examined relations between motor dimensions and core/comorbid impairments in young children with ASD, few studies have examined such relations in school‐age children/adolescents with ASD. This paper conducts a further multidimensional study of which motor domains (i.e., gross‐motor including visuo‐motor or multilimb coordination/planning, fine motor [FM] or general coordination [GC] skills) best distinguish subgroups of school‐age children/adolescents with ASD and help predict core and comorbid impairments after accounting for age and sex. Visuomotor, FM and certain GC skills were better at explaining variations in/predicting social communication impairments whereas FM skills were slightly better at explaining variations in/predicting RB severity. Multilimb coordination/planning and FM skills explained variations in/predicted cognitive delays whereas visuomotor and FM skills explained variations in and better predicted language delays. All three motor dimensions explained variations in/predicted functional delays. This study provides further evidence for inclusion of motor impairments within the ASD definition (criteria or specifiers).Lay SummaryGross‐motor skills were related to social communication and functional delays of children with ASD (visuomotor skills related to language delays and multilimb coordination/planning skills related to cognitive delays). Fine‐motor skills were related to repetitive behavior severity, language, cognitive, and functional delays in ASD. Diagnosticians should recommend systematic motor screening, further evaluations, and treatments for children at‐risk for and diagnosed with ASD. Motor advocacy and enhanced public/clinical community awareness is needed to fulfill the unmet motor needs of children with ASD.
Tunneling the barriers of blockchain technology in remanufacturing for achieving sustainable development goals: A circular manufacturing perspective
Authors: Govindan Kannan 
Published: March 2022

AbstractAs a concern with manufacturing industries, circular economy (CE) practices—often labeled “circular manufacturing (CM)”—are industrial tasks through which several circular economy principles have been integrated. Among these circular manufacturing strategies, “3R” (recycle, refurbish/remanufacture, and reuse/redistribute) is the key strategy that assists the manufacturing industry with closing the loop for sustainability. An effective inclusion and management of 3R lead a firm to a greater likelihood of successfully integrating CE and CM. In recent years, remanufacturing has gained greater prominence, especially with the emergence of technology, including cyber‐physical systems. These technologies assist the remanufacturing firm with efficient take‐back systems through tracking. However, data transferred through these technologies among value chain partners in remanufacturing are not reliable. Due to the lack of trust and transparency, value chain partners are hesitant to participate in remanufacturing supply chains. To address the limitation of technologies in remanufacturing, blockchain has been introduced to secure the data. Despite the advantages of blockchain technology, practitioners face difficulties in integrating these blockchain technologies into the remanufacturing context. Several earlier studies addressed the challenges of implementing blockchain, but no earlier studies have specifically examined remanufacturing industries, which are entirely different from forward supply chain industries. Concerning the fact, this study identifies the barriers that exist with the implementation of blockchain technology in the application of the remanufacturing sector. A framework has been proposed and validated in a Danish automotive parts remanufacturing company. Multi‐criteria decision‐making method has been used to identify the effective and most influential barriers among common barriers. Results reveal that “scaling of technology” (B6) is the key barrier of BCT implementation in remanufacturing context. This study concludes with useful discussions based on the results along with the recommendations to eradicate those influential barriers and their respective impacts on SDGs (SDG4, SDG8, SDG9, and SDG17). Finally, this study sheds light on future enhancements on the integration of blockchain technology in remanufacturing to reap several benefits of circular manufacturing.

Published: March 2022

AbstractThe paper examines the impact of banks environmental performance on their financial and market performance. We collect data from 56 gulf cooperative council (GCC) banks for the period 2010–2019. We apply ordinary least square (OLS), fixed effect, and generalized method of moments (GMM) estimation techniques and show that GCC banks' environmental performance negatively affects their accounting performance. The results, however, exhibit no significant impact of banks' environmental performance on market performance. Moreover, conventional banks have better environmental performance than their Islamic counterparts. Our results are consistent across different estimation techniques after controlling for endogeneity issues. The findings of the study are novel and offer important policy implications for management, regulatory authority, and environmental activists.

AbstractThe goal of this study was to fabricate bioactive cell‐laden biocomposites supplemented with bone‐derived decellularized extracellular matrix (dECM) with calcium phosphate ceramic, and to assess the effect of the biocomponents on the osteogenic and odontogenic differentiation of human dental pulp stem cells (hDPSCs). By evaluating the rheological properties and selecting printing parameters, mechanically stable cell‐laden 3D biocomposites with high initial cell‐viability (>90%) and reasonable printability (≈0.9) were manufactured. The cytotoxicity of the biocomposites was evaluated via MTT assay and nuclei/F‐actin fluorescent analyses, while the osteo/odontogenic differentiation of the hDPSCs was assessed using histological and immunofluorescent analyses and various gene expressions. Alkaline phosphate activity and alizarin red staining results indicate that the dECM‐based biocomposites exhibit significantly higher osteogenic activities, including calcification, compared to the collagen‐based biocomposites. Furthermore, immunofluorescence images and gene expressions demonstrated upregulation of dentin matrix acidic phosphoprotein‐1 and dentin sialophosphoprotein in the dECM‐based biocomposites, indicating acceleration of the odontogenic differentiation of hDPSCs in the printed biocomposites. The hDPSC‐laden biocomposite was implanted into the subcutaneous region of mice, and the biocomposite afforded clear induction of osteo/odontogenic ectopic hard tissue formation 8 weeks post‐transplantation. From these results, we suggest that the hDPSC‐laden biocomposite is a promising biomaterial for dental tissue engineering.

AbstractBackgroundStudies are trying to add immunotherapy to gemcitabine and cisplatin (GP) induction chemotherapy, the standard therapy, in nasopharyngeal carcinoma (NPC) patients with locoregionally advanced disease. However, how the immune system responds to GP remains unknown.MethodWe examined the dynamic changes of circulating immune cells and plasma cytokines in NPC patients administered with GP.ResultAfter GP administration, immunosuppressive myeloid cells, including CD11b+CD14+ monocytes, CD33+ myeloid cells, CD33+CD11+ myeloid cells, total MDSCs (CD33+CD11+HLA‐DR−/low), monocytic MDSCs, and granulocytic MDSCs decreased significantly. The regulatory T cells and B cells, two important suppressive lymphocyte subpopulations, also decreased. On the other hand, the levels of CD3+ T cells, total B cells, central memory CD4+ T cells, and pro‐inflammatory cytokines (including Interleukin [IL]‐1β, IL‐6, IL‐2, IL‐5, and IL‐8) increased significantly after GP administration. Besides, GP chemotherapy did not weaken the cytotoxic activity and proliferative capacity of T cells.ConclusionOur results showed the immune modulation effect of GP induction chemotherapy in locoregionally advanced NPC, providing a solid basis for its combination with immunotherapy.

Published: March 2022

AbstractThe authors examine trends in how successful guided pathways colleges communicate transfer options to 4‐year institutions via their institutional websites so that students—the ultimate benefactors of guided pathways initiatives—can discover and pursue the transfer partnership pathways. Institutions in the two states included in this review were selected based on nationally recognized exemplary practices and commitment to student success and outcomes. Three dimensions were explored in this website content analysis: How easy is it to find information (accessibility)? How is the information organized (presentation)? What relevant content is communicated (information)? The authors found that exemplary pathways institutions place pathways information prominently on their websites’ home page, use similar language to describe pathways information and in multiple places on the website, and provide a connection to supportive transfer resources. The authors present the conclusions, discuss implications drawn from this study, and provide recommendations for practice.
N‐Heterocyclic Carbenes Carrying Weakly Coordinating Anions
Authors: Ho Luong Phong , Tamm Matthias 
Published: March 2022

AbstractIn this Concept article we provide a brief overview of the design and preparation of N‐heterocyclic carbenes carrying weakly coordinating anions (WCA‐NHCs). The anionic charge in these ligand systems is located on an exocyclic group, for example, B(C6F5)3, tethered to the backbone of the imidazole ring, thus resembling a weakly coordinating moiety. With the general guiding principle behind the application of WCA‐NHCs being the conversion of otherwise cationic NHC complexes into their overall neutral congeners, numerous transition metal as well as main group element complexes were isolated during the last decade, which are summarized herein.
Cellulose Nanocrystal‐supported Pd‐Co Bimetallic Catalyst for Selective Hydrogenation of 3‐Nitrostyrene

Published: March 2022

AbstractHerein, we prepared an even‐dispersed bimetallic Pd−Co nanoparticles supported on cellulose nanocrystal (CNC) matrix (denoted as Pd−Co/CNC‐x; x is the added Co/Pd molar ratio during the preparation) for selective hydrogenation of 3‐nitrostyrene (NS). The optimized Pd−Co/CNC‐2.5 catalyst showed the highest catalytic activity with TOF value of 2570 h−1 and 94.1% selectivity of 3‐ethylnitrobenzene (ENB) in methanol under 3 bar H2 at 50 °C. The reaction pathway revealed that the Pd−Co/CNC‐2.5 catalyst exhibited the high priority on the C=C bonds hydrogenation, while the 3‐ethylaniline (EA) was the over‐hydrogenation product from NS via ENB. The structure‐activity relationship study demonstrated that the synergistic effect of Pd−Co in Pd−Co/CNC‐2.5 played a crucial role in the hydrogenation of NS. Moreover, compared to the monometallic Pd/CNC catalyst, the kinetic analysis revealed a relative lower reaction barrier of CNC supported Pd−Co nanoparticles. This exploration will provide a guidance for the catalyst construction in the selective hydrogenation of the unsaturated C=C bonds.
