Published: July 2024

AbstractPerovskite/silicon tandem solar cells (PVSK/Si TSCs) have emerged as a promising photovoltaic technology toward achieving a high power conversion efficiency (PCE) along with cost‐effective manufacturing. The PCE of PVSK/Si TSCs has skyrocketed to a certified 33.9%, surpassing the theoretical limit of any single‐junction solar cell. This achievement is partially attributed to advancements in surface textures for Si bottom cells. In this regard, we present an overview of the recent developments concerning surface textures of Si in monolithic PVSK/Si TSCs, including planar, pyramid texture, and nanotexture. Following, the prevailing perovskite deposition methods on these textures are thoroughly discussed, and the corresponding challenges are evaluated. Additionally, we provide a summary of the advanced morphological, structural, optical, and electrical characterization techniques being utilized for theses textures. Finally, the prospects for further development of PVSK/Si TSCs are outlined, including designing novel textures with industrial compatibility, developing perovskite deposition methods with scalability, and exploring more pertinent characterization techniques for textured PVSK/Si TSCs.

Published: July 2024

AbstractThere is significant need for alcohol use disorder (AUD) treatment among lesbian, gay, and bisexual (LGB) individuals. Furthermore, utilization among LGB individuals is below indicated treatment need due to interpersonal and structural barriers. A hierarchical logistic regression examined relationships among perceived public, interpersonal, and healthcare discrimination in relation to treatment utilization using secondary data from a subsample of the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions‐III. Findings indicate that increased public and interpersonal discrimination is associated with higher likelihood of healthcare discrimination. Healthcare discrimination predicted higher AUD treatment use. Clinical implications and recommendations for future research are discussed.

Published: July 2024

AbstractThe aim of this study was to evaluate the anticancer effects of piceatannol, a natural stilbenoid, on human neuroblastoma cells. In order to accomplish this goal, we performed various cellular assays, including the XTT cell proliferation assay for cell viability, colony formation assay for colony formation capacity, FITC Annexin V and cell death detection kit for apoptosis, matrigel invasion assay for invasion capacity, intracellular reactive oxygen species (ROS) red dye for intracellular ROS levels, TMRM staining method for mitochondrial membrane potential (MMP), and the CYTO‐ID autophagy detection kit for autophagy. Furthermore, we analyzed the expression levels of genes associated with apoptosis and autophagy using RT‐qPCR. Based on our findings, piceatannol exhibited cytotoxic effects on neuroblastoma cells. Besides, treatment with piceatannol at both 50 and 100 μM concentrations for 72 h decreased colony formation, induced apoptosis and autophagy, inhibited cell invasion, decreased MMP, and increased ROS levels in SH‐SY5Y cells. In addition, we observed significant upregulation in the expression levels of CASP8, BECLIN, ATG5, ATG7, and MAPILC3A genes between the two doses. These results suggest that piceatannol enhances autophagic activity and induces caspase‐dependent apoptosis, indicating its potential as a therapeutic agent against neuroblastoma cells.

AbstractMetal halide perovskites are crystalline materials with a sharp increase in popularity and rapidly becoming a major contender for optoelectronic device applications. In this work, we provide the optoelectronic features of a possible novel candidate, ZSnCl3 (Z = Na/K) Sn‐based on a detailed numerical simulation. The output of the current computations is compared to the results that are currently available, and a respectable agreement is noted. The studied compounds were cubic in nature and structurally stabe. The mechanical properties reflect the mechanical stability and ductility of the proposed materials. The Sn‐based single perovskite compounds proposed in this study are mechanically stable and ductile. The narrow direct band gap for NaSnCl3 and KSnCl3 are 1.36 eV and 1.47 eV, respectively, using the HSE06 hybrid function with the Boltztrp2 integrated in Quantum ESPRESSO (QE) software. The effective use of these compounds in perovskite solar cells and other optoelectronic applications was confirmed by optical absorption spectral measurements conducted in the photon energy range of 0–20 eV.

Published: July 2024

AbstractBACKGROUNDThe production of value‐added chemicals from pyrolysis oil or its fractions is of great significance for the valorization of biomass. Diols, including ethylene glycol (EG) and 1,2‐propylene glycol (1,2‐PG), are important bulk chemicals with widespread industrial applications. Here we investigated the production of diols from pyrolysis oil water‐soluble fraction (WS) using a hybrid catalyst (Ni + H2WO4).RESULTSFirstly, levoglucosan, glycolaldehyde and acetol, three main components in WS, were respectively selected as the single model compound, and their respective conversions into diols were investigated at different temperatures for different reaction times. The result showed the optimum reaction temperature and time were 180 °C and 2 h respectively, under which a EG yield of 53.8% and 1,2‐PG yield of 5.2% were obtained from levoglucosan conversion, a EG yield of 98.6% was obtained from glycolaldehyde conversion, and a 1,2‐PG yield of 98.5% was obtained from acetol conversion. The reaction pathway of levoglucosan conversion was analyzed. Secondly, the model mixture of levoglucosan, glycolaldehyde and acetol was used to simulate the real WS, and their conversion was investigated at different ratios of H2WO4 to Ni. The result showed the optimum catalyst composition was 0.15 g H2WO4 and 0.3 g Ni, under which a EG yield of 76.4% and 1,2‐PG yield of 38.4% were obtained. Thirdly, the real original WS was converted under the optimum reaction conditions and the result only gave a EG yield of 19.1% and 1,2‐PG yield of 25.8% (based on the carbon moles of main substrates), which were much less than the two yields of model mixture. That was related to the presences of other types of chemicals in original WS. After the original WS being adsorbed by activated carbon, the yields of EG and 1,2‐PG could be increased to 39.2% and 37.9%, respectively.CONCLUSIONThe presences of certain other types of chemicals (such as acids, furans, phenolics and cyclopentanones) in original WS inhibited the production of diols. The activated carbon adsorption could efficiently remove most of furans, phenolics and cyclopentanones in original WS and increased significantly the diols yields. © 2024 Society of Chemical Industry (SCI).

Published: July 2024

AbstractBACKGROUNDAcetaminophen, also known as paracetamol, has been notably detected in aquatic environments, including wastewater, surface water and drinking water, causing significant concern within the scientific and environmental research communities. This study focuses on two main objectives: (i) optimizing corn cob‐based activated carbon (CCAC) through response surface methodology for the adsorption of acetaminophen and (ii) simulating the acetaminophen adsorption process using the polymath mass transfer (PMT) model.RESULTSThe optimized CCAC was prepared via physiochemical activation under microwave radiation (265 W power) for 6 min, with a KOH impregnation ratio of 0.50 g g−1. This process resulted in a high Brunauer–Emmett–Teller surface area of 976.29 m2 g−1, accompanied by a corresponding pore volume of 0.39 cm3 g−1 and a pore diameter of 2.38 nm. The adsorption study, employing differential initial concentrations (ranging from 5 to 30 mg L−1) of acetaminophen, revealed a substantial adsorption capacity of 22.43 mg g−1 (74.77%) at 30 °C and 20.74 mg g−1 (69.13%) at pH 6. The PMT model indicated an adsorption capacity (Qm) of 21.14 mg g−1, with an error of 5.75%, demonstrating high precision compared to the experimental result. Additionally, the calculated R2 values equal to or above 0.90 indicated strong agreement between the PMT model and experimental data.CONCLUSIONThus, applying the PMT model proved to be economical and cost‐effective, providing accurate predictions on surface area during adsorption performance compared to the time‐consuming and costly process of conducting characterizations. © 2024 Society of Chemical Industry (SCI).

AbstractPer‐ and polyfluoroalkyl substances (PFAS) are refractory anthropogenic chemicals and current treatment processes at municipal water resource recovery facilities (WRRFs) cannot efficiently degrade them, hence, these chemicals cycle through the environment. Certain PFAS can be concentrated in biosolids from WRRFs and are commonly land applied for beneficial reuse. Given recent advances in measurement of PFAS, documentation of the range of concentrations in pre‐stabilized sludge and stabilized biosolids is critical to evaluating treatment best practices and assessing potential human health and ecological risks. In this study, pre‐stabilized sludge and post‐stabilized biosolids samples were collected from 12 major WRRFs across the United States. PFAS were analyzed using Environmental Protection Agency (EPA) Method SW846‐3500C/537.1, and Draft EPA Method 1633, by one commercial laboratory and two university research laboratories, respectively. Results comparison among laboratories demonstrated statistical differences in PFAS concentrations among split samples. For example, 5:3 FTCA (fluorotelomer carboxylic acid) concentrations in post‐stabilized sludge at Lab 1 were measured at 21 ng/g (dry), while they were detected at 151 ng/g (dry) in Lab 3. Further, higher PFAS concentrations were observed in post‐stabilized biosolids compared to pre‐stabilized sludges, regardless of the laboratory or analysis method, even when solids destruction through solids stabilization was considered. Further research is required to refine methods for analyses of PFAS in sludge and biosolids samples from WRRFs prior to being used for development of regulatory actions as well as understanding how various treatment protocols could impact concentrations of PFAS in land‐applied biosolids.
Multicolor Turán numbers II: A generalization of the Ruzsa–Szemerédi theorem and new results on cliques and odd cycles

Published: July 2024

AbstractIn this paper we continue the study of a natural generalization of Turán's forbidden subgraph problem and the Ruzsa–Szemerédi problem. Let denote the maximum number of edge‐disjoint copies of a fixed simple graph that can be placed on an ‐vertex ground set without forming a subgraph whose edges are from different ‐copies. The case when both and are triangles essentially gives back the theorem of Ruzsa and Szemerédi. We extend their results to the case when and are arbitrary cliques by applying a number theoretic result due to Erdős, Frankl, and Rödl. This extension in turn decides the order of magnitude for a large family of graph pairs, which will be subquadratic, but almost quadratic. Since the linear ‐uniform hypergraph Turán problems to determine form a class of the multicolor Turán problem, following the identity , our results determine the linear hypergraph Turán numbers of every graph of girth 3 and for every up to a subpolynomial factor. Furthermore, when is a triangle, we settle the case and give bounds for the cases , as well.
Thin edges in cubic braces

Published: July 2024

AbstractFor a vertex set in a graph, the edge cut is the set of edges with exactly one end vertex in . An edge cut is tight if every perfect matching of the graph contains exactly one edge in . A matching covered bipartite graph is a brace if, for every tight cut , or , where . Braces play an important role in Lovász's tight cut decomposition of matching covered graphs. The bicontraction of a vertex of degree two in a graph, with precisely two neighbours and , consists of shrinking the set to a single vertex. The retract of a matching covered graph is the graph obtained from by repeatedly the bicontractions of vertices of degree two. An edge of a brace with at least six vertices is thin if the retract of is a brace. McCuaig showed that every brace of order at least six has a thin edge. In a brace of order six or more, Carvalho, Lucchesi and Murty proved that has two thin edges, and conjectured that contains two nonadjacent thin edges. Further, they made a stronger conjecture: There exists a positive constant such that every brace has thin edges. By showing that, in every cubic brace of order at least six, there exists a matching of size at least such that every edge in is thin, we prove that the above two conjectures hold for cubic braces.

For any there exists such that if an ‐vertex ‐free graph contains at least copies of , then the edit distance of and the ‐partite Turán graph is at most . We say that is weakly F‐Turán‐stable if the same holds with the Turán graph replaced by any complete ‐partite graph . It is known that such stability implies exact results in several cases. We show that complete multipartite graphs with chromatic number at most are weakly ‐Turán‐stable. Partly answering a question of Morrison, Nir, Norin, Rzażewski, and Wesolek positively, we show that for every graph , if is large enough, then is ‐Turán‐stable. Finally, we prove that if is bipartite, then it is weakly ‐Turán‐stable for large enough.

Published: July 2024

ABSTRACTHerein, we demonstrate an efficient method for multi‐deuterium labelling of pirtobrutinib—a Bruton's tyrosine kinase inhibitor recently approved by the FDA—using a straightforward hydrogen isotope exchange (HIE) reaction. A remarkably high level of deuterium incorporation was achieved using an excess of a Kerr‐type iridium catalyst. The key factor in the significant deuterium labelling was the decision to employ a deuterium uniformly labelled solvent, chlorobenzene‐d5, at an elevated temperature. Virtually, no d0–d3 species were detected, with only traces of d4–d5 isotopomers (< 5%) observable in the mass spectrum of pirtobrutinib‐d8, fulfilling requirements for stable isotope‐labelled internal standard. The labelled compound—mainly consisting of isotopomers d6–d9 at 82.4% of the total abundance—was isolated in a high yield (73%) and purity (99%). Noteworthy, fluorine group acting as a directing group was observed for the first time. Significant incorporation of deuterium in ortho‐positions, exceeding 87%, was observed. Interestingly, chlorinated solvent used in the HIE reactions was non‐specifically deuterated yielding up to 0.42 deuterium per chlorobenzene molecule even at an exceptionally low iridium catalyst loading of 4.17 × 10–2 mol%.
Understanding non‐stationarity patterns in basin‐scale hydroclimatic extremes
Authors: Singh Achala , Sharma Priyank J. , Teegavarapu Ramesh S. V. 
Published: July 2024

AbstractStationarity, a cornerstone in hydraulic design, is now under scrutiny due to anthropogenic activities and climate change. Numerous studies have sought to identify non‐stationarity (NS); however, a comprehensive assessment of time invariance in all statistical properties of a time series is less explored. This study presents a non‐overlapping block‐stratified random sampling (NBRS) framework leveraging the strengths of several nonparametric tests to assess NS. The NBRS approach exclusively detects NS and distinguishes between various forms of stationarity, including weak and strict. A variant of NBRS is proposed in this study to identify the underlying stochastic process(es) influencing NS in hydroclimatic extremes. Furthermore, a nonparametric clustering approach is used to unveil spatial clusters showcasing NS due to shifts in mean, variance, distribution of time series or a combination of these factors. A comparative assessment of the modified NBRS approach with traditional trend and change point methods is also performed. The proposed methodology is applied to assess the presence of NS in 28 hydroclimatic indices derived for the west‐central river basins of India, exhibiting diverse physio‐climatic settings, for the study period 1973–2021. The modified NBRS approach rigorously explores NS within extreme hydroclimatic indices, conclusively pinpointing its root causes and profound implications for hydrologic design. The applicability of the modified NBRS approach to gridded and point datasets is also demonstrated. The findings highlight the limitations of conventional trend and change point tests in capturing time‐invariant characteristics in heteroscedastic variables (such as streamflow and rainfall extremes) compared to the NBRS approach. The research reveals that NS in rainfall and streamflow extremes primarily results from distributional shifts, whilst temperature extremes are influenced by changes in mean and distribution properties. This research deepens our understanding of the evolving patterns in hydroclimatic extremes in a changing climate.
Toward a more complete understanding of institutional logic configuration in an merger project
Authors: Thelisson Anne‐Sophie 
Published: July 2024

AbstractThe frequency and scale of mergers and acquisitions (M&A) have significantly increased in the last two decades, in spite of continuous reports on their high failure rates. M&A scholars call for insights to be sought on the merger process to help understand the complexity of these operations and decrease their failure rate. M&A scholars advocate paying attention to institutional logics' configuration shaping a firm's decisions to grasp merger process complexity. Institutional studies show how specific logics have a powerful influence on the strategic decisions and priorities of organizations. Yet, few studies have empirically combined multiple levels by framing logics' configuration fostering specific strategic decisions. This study addresses this issue. Using a longitudinal case study, we analyze how institutional logics' configuration at organizational and inter‐organizational levels supports firms' strategic decisions to merge and to end the deal. We demonstrate that despite the alignment of logics at the organizational level, the multiplicity of logics at the inter‐organizational level led to deal failure.

AbstractBACKGROUNDCodonopsis pilosula var. modesta (CPVM) is a famous medicinal and edible plant of Campanulaceae. However, fresh CPVM roots (FCPVR) are prone to softening, browning and spoilage after concentrated harvesting in the main production area of Gansu Province, China in autumn, which poses great challenges to their large‐scale storage and modern processing. In this study, effects of chitosan (CS), natamycin (NA) and modified atmosphere agent (MA) on the postharvest quality of FCPVR were first investigated. The roots after different treatments were stored at 4 °C and relative humidity of 75 ± 5% for 100 days. Their overall quality changes were evaluated from three perspectives: physiological quality, endophytic bacterial community and volatile organic compounds.RESULTSThe clustering heatmap and principal component analysis results indicated that CS (2 g kg−1), NA (0.5 g kg−1) and MA (5 g) had a synergistic effect on physiological quality. The roots in the CS + NA + MA group maintained better physiological state, effective components and antioxidant capacity throughout the storage process. On this basis, compared with room temperature storage, the relative abundance of the main spoilage bacterium Pseudomonas in the CS + NA + MA group roots decreased by 44% on the 100th day of storage. Furthermore, after CS + NA + MA composite treatment, the roots produced richer esters with fruit aroma during low‐temperature storage.CONCLUSIONSThe CS + NA + MA composite treatment could maintain the physiological quality and flavor of FCPVR, inhibit spoilage by microbial contamination and maintain the optimal quality during low‐temperature storage for up to 100 days. © 2024 Society of Chemical Industry.
