AbstractBulk photovoltaic effect (BPVE) triggered by spontaneous polarization in polar organic–inorganic hybrid perovskites (OIHPs) has brought unprecedented development opportunities for self‐powered ultraviolet photodetection. However, the currently reported ultraviolet optoelectronic devices are dominated by low‐dimensional hybrid perovskites, in which low carrier mobility limits the photoelectric conversion efficiency. Herein, we report for the first time a polar three‐dimensional OIHPs, namely MHyPbBr3 (1, MHy=methylhydrazine), that achieves high‐performance self‐driven ultraviolet photodetection. Benefitting from the large spontaneous polarization and excellent semiconductor attributes, 1 exhibits 0.33 V BPVE and high carrier mobility lifetime product (μτ) of 1.972×10−3 cm−2 V−1 under ultraviolet illumination. Notably, such merits contribute to efficient self‐driven photodetection, where responsivity (R) and detectivity (D*) reach up to 198 mA W−1 and 1.42×1013 Jones, surpassing most reported ultraviolet photodetectors. Furthermore, based on the reversible phase transition of 1, we have achieved controllable ultraviolet photoelectric detection. This work will shed light on the fabrication of high‐response self‐driven ultraviolet optoelectronic devices.

AbstractScreen printing has emerged as a leading candidate for industrial‐scale fabrication of perovskite photovoltaics. However, strong solvent‐solute interaction in conventional formulations accelerates the preferential crystallization of perovskites at points, hindering the progressive phase evolution from point to line to plane. In this work, we introduced halogen ions to weaken solvent‐solute interactions, achieving the reduced Pb⋅⋅⋅O coordination strength counterbalanced by enhanced Pb−I bonding interactions. This weakened interaction delays formamidinium iodide participation in rapid phase transitions to α‐formamidinium lead iodide, enabling controlled crystallization kinetics. The optimized screen‐printed perovskite solar cells demonstrate remarkable power conversion efficiencies (PCE) of 21.8 % for 0.05 cm2 devices and 18.95 % for 5 cm×5 cm mini‐modules (active area: 12.60 cm2). Furthermore, this strategy exhibits broad process compatibility, achieving 23–24 % PCEs for both blade‐coating and spin‐coating devices fabricated under ambient conditions (25–30 °C, 35–50 % relative humidity). These breakthroughs highlight the universal potential of coordination engineering for scalable perovskite photovoltaics.

AbstractWhile enantioenriched alcohols are highly significant in medicinal chemistry, total synthesis, and materials science, the stereoselective synthesis of tertiary alcohols with two adjacent stereocenters remains a formidable challenge. In this study, we present a dual catalysis approach utilizing photoredox and nickel catalysts to enable the unprecedented chemoselective functionalization of tertiary allylic C−H bonds in allyl ethers instead of cleaving the C−O bond. The resulting allyl‐Ni intermediates can undergo coupling with various aldehydes, facilitating a novel enantioconvergent approach to access extensively functionalized homoallylic sec,tert‐vicinal diols frameworks. This protocol exhibits nice tolerance towards functional groups, a broad scope of substrates, excellent diastereo‐ and enantioselectivity (up to 20 : 1 dr, 99 % ee). Mechanistic studies suggested that allyl‐NiII acts as the nucleophilic species in the coupling reaction with carbonyls.

ABSTRACTTo advance our study on the GLUT's glucose recognition binding site and enhance the effectiveness of targeted anticancer compounds based on our encouraging findings, glycogenated metal complexes have shown promise in combating colon cancer (HCT‐116) through salicylaldehyde‐D‐glucosamine Schiff base(H2L), we proceed with our research utilizing various colon cell lines with different metal ions known for their potent anticancer effect. Newly synthesized complexes with the formulae Zn (HL)2, (CH3)2Sn(HL)2, and [Ru(L)(HL)H2O].H2O are directed against two colon cell lines (HCT‐116 and Caco‐2). Different characterization techniques are used to confirm structures. DFT was used to structurally optimize the synthesized compounds. The particle size distribution was performed for all chelates. All compounds revealed remarkable anticancer activities especially the ligand and Ru (III) complex recording IC50 values of 21.73 μg/mL against HCT‐116 and 49.53 μg/mL against Caco‐2 cell lines, respectively. The results showed that GLUT's glucose recognition binding site can attract the sugar‐conjugated compounds. The efficiency of the ligand and its Ru (III) complex was confirmed through the evaluation of GSH, SOD, MDA, NO, and LDH levels. The high affinity of metal glycoconjugates for DNA binding was explored using electrophoresis. Additionally, the metal chelates showed significant antimicrobial activity. The ligand and its Zn (II) complex showed bactericidal activity against the strain of Helicobacter pylori. The docking simulation was performed to explore the active amino acids participate in the biological interaction.
Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride
Authors: Muluneh Habtamu Anagaw 
Published: February 2025

AbstractThe superconductor UTe2 has garnered considerable attention due to its unique spin‐triplet pairing and high upper critical magnetic field, making it a promising candidate for exploring unconventional superconductivity. This study presents a theoretical investigation into the angle dependence of the upper critical magnetic field HC2 and the temperature‐dependent density of states (DOS) within UTe2. By employing anisotropic Ginzburg–Landau theory alongside microscopic modeling, the orientation‐dependent behavior of HC2 is analyzed along key crystallographic axes, particularly the a‐, b‐ and c‐axes, which demonstrate critical fields of ≈7, 15, and 11 T respectively. These results indicate a strong anisotropy in HC2, with a peak along the b‐axis, suggesting a profound alignment effect of the spin‐triplet pairs with the magnetic field. Additionally, temperature‐dependent DOS calculations reveal a pronounced increase in states near the Fermi level at lower temperatures, supporting the presence of unconventional pairing with potential nodal gaps. These findings suggest a complex interplay between spin fluctuations and electronic correlations, contributing to the robust superconducting phase in UTe2 and also provides deeper insights into the mechanisms driving superconductivity in UTe2 and highlights its potential for applications requiring high‐field superconductors.

ABSTRACTBycatch is the greatest threat facing marine mammals globally. In the United States (US), there have been significant efforts to reduce marine mammal bycatch in commercial fisheries, particularly through the implementation of the 1994 amendments to the Marine Mammal Protection Act. However, trends in marine mammal bycatch in US commercial fisheries have not been evaluated in over a decade. We assessed trends in US marine mammal bycatch for 130 stocks of 51 species from 1990 to 2017 according to taxon, region and gear type based on National Marine Fisheries Service Stock Assessment Reports using the bycatch metric ‘mortalities and serious injuries’. We estimated that total annual marine mammal bycatch in US fisheries was 4296 ± 1789 individuals (mean ± SD), with the majority of bycatch occurring in gillnets (83%). The proportion of pinniped bycatch (52%) was slightly higher than that of cetaceans (48%). After decreasing from 1990 to 2002, there was no change in total marine mammal bycatch in all US fisheries from 2002 to 2017, although pinniped bycatch continued to decline throughout the series. Whereas reductions in marine mammal bycatch continued through 2017 in the Atlantic–Gulf of Mexico–Caribbean region, reductions in the Pacific and Alaskan regions had halted or reversed by 2006. Although a more fine‐scale evaluation is needed to determine the exact drivers of changes in marine mammal bycatch, our results agree with previous studies in suggesting some success of US bycatch mitigation measures.

AbstractAnthracenes have become a rising star in organic semiconducting materials owing to the high stability and superior mobility. In spite of solution processability for large area fabrication, anthracene‐based polymers lag far behind small‐molecule counterparts in terms of molecular diversity and carrier mobility. Herein, we synthesized two anthracene‐based polymers via Stille reaction by incorporation of two structurally similar units bithophene and cyclopentadithiophene. Anthracene‐bithophene alternating polymer (PAnBT) polymer was calculated to take a twisted backbone conformation, showing very poor mobility of 3.6×10−4 cm2 V−1 s−1 with relatively low crystallinity and coarse film morphology. In contrast, anthracene‐cyclopentadithiophene alternating polymer (AnCPDT) polymer was calculated to adopt a planar backbone conformation and displayed significantly improved mobility up to 2.2×10−2 cm2 V−1 s−1 with relatively high crystallinity and smooth film morphology, which is one of the highest mobilities for anthracene‐based polymers. The different substitution positions of alkyl chains account for the varied polymer backbone conformations, resulting into a big discrepancy in film microstructures and charge carrier mobilities. This work demonstrates that design of planar backbone conformation is beneficial to improve charge transport characteristics for anthracene‐based polymers.

Published: February 2025

AbstractIn this study, we introduce a chelation‐free approach to the dual‐functional detection and removal of Hg2+ ions using two novel silica‐based materials, AnSiO2 and PySiO2, functionalized with anthracene and pyrene, respectively. These materials were synthesized via a two‐step process involving the direct condensation of triethoxyvinylsilane onto silica gel surfaces, followed by Heck coupling with 9‐bromoanthracene and 1‐bromopyrene, respectively. They exhibit strong fluorescence emission in aqueous solutions, particularly at pH 6. Upon exposure to Hg2+ ions, both materials undergo significant fluorescence quenching, enabling sensitive and selective detection of Hg2+. PySiO2 demonstrated superior performance compared to AnSiO2, with a lower detection limit (0.29 μM) and a higher Stern‐Volmer constant (2×106 M−1). Additionally, PySiO2 shows a higher adsorption capacity for Hg2+, reaching 54.04mg/g, as confirmed by ICP‐MS analysis. The sensing mechanism involves charge‐dipole and π‐electron interactions, supported by spectroscopic analyses. Reusable for four cycles, PySiO2 effectively removes Hg2+ from aquaculture water, showcasing its potential for scalable, cost‐effective, and simultaneous detection and remediation of mercury in real‐world applications.

AbstractTwo carbazole derivatives BPA‐BNC and 4BPABNC are designed and synthesized to explore the probable dualemission behavior and mechanisms. BPA‐BNC contains two arylamino donors and one B−N multi‐resonance (MR) segment at 3,6,9‐positions of a single carbazole, while 4BPABNC has two extraarylamine donors at 1,8‐positions in addition to the above substituent groups. Two compounds in polar solvents show a clear dual emission peaked at near 490 and 540 nmwith high photoluminescence quantum yields of up to 98 %, short delayed lifetimesand extremely small single‐triplet splitting energies. The dual emissions originate fromthe MR and through‐bond charge transfer transitions, which are supported by theoretical calculation and experimental data. The solution‐processed devices based on BPA‐BNC and 4BPABNC also exhibit dual emissions and achieve the maximum external quantum efficiencies(EQEs) of 13.1 %and 12.7 %, whereas the model MR molecule provides an EQE of 7.3 % under the same device architecture.

AbstractIn this work, two novel types of bipolar phosphorescent host materials derived from triazine and indenocarbazole, which were 5‐(7‐(4,6‐diphenyl‐1,3,5‐triazin‐2‐yl)‐9,9‐dimethyl‐4b,8a‐dihydro‐9H‐fluoren‐2‐yl)‐7,7‐dimethyl‐5,7‐dihydroindeno[2,1‐b] carbazole (m‐TFFCz) and 5‐(7‐(4,6‐diphenyl‐1,3,5‐triazin‐2‐yl)‐9,9‐dimethyl‐4b,8a‐dihydro‐9H‐fluoren‐2‐yl)‐5H‐benzofuro[3,2‐c]carbazole (m‐TFBFCz). Both host materials exhibit remarkable thermal stability, for example, their higher glass transition temperatures (Tg) exceed 170 °C and higher decomposition temperatures (Td) above 400 °C. The m‐TFFCz and m‐TFBFCz have high triplet energy (ET) of 2.67 eV and 2.75 eV, and their highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) are completely separated. In addition, the red PhOLEDs based on two host materials of m‐TFFCz and m‐TFBFCz exhibit the maximum external quantum efficiency (EQEmax) of 20.31 % and 25.40 %, and the time it takes for a device to decay from its initial maximum brightness to 95 % of its original brightness (T95) are 8.96 h and 102.63 h, respectively. Based on the results, synthesizing bipolar phosphorescent host materials using triazines is a viable design method for high‐efficiency PhOLEDs with great thermal stability.

ABSTRACTThe proposed study uses a special procedure to verify that an analyte assessment operation is sustainable and environmentally friendly. When the targeted analyte molecule (alogliptin drug, ALT) lacks chromophoric or fluorogenic groups, it cannot be analyzed without marking or structural amendment. The obeyed phenomenon (marking process) could be achieved via fluorescence probing or marking using tagging agents. An innovative reagent pair consisting of trioxosulfate ion and o‐Phthaldialdehyde (OPD) is used in the described analytical approach. This reagent is used to build a novel fluorescent nucleus and can be detected using the developed fluorimetric approach. ALT's amino moiety could condense trioxosulfate/OPD. This study presents a new, facile, green, sustainable fluorometric assay of the ALT drug. The product's response is linear at 50.00–800.00 ng mL−1 concentration range (LOD = 15.74 and LOQ = 47.69 ng mL−1). The method validation was considered following the International Council for Harmonisation (ICH) recommendations. The planned probe was applied to the crude powder and dose forms, and excipients had no influence. The planned analytical procedure is identified as sustainable and white by the WAC (White Analytical Chemistry) indications following the Green/Red/Blue (RGB 12) pattern. Additionally, new tools (BAGI and GSST) were applied to the current work.

ABSTRACTBackgroundIn vitro fertilization (IVF) has been acknowledged as the primary assisted reproductive technique for fertilizing oocytes outside the female reproductive system. Sleep disorders are likely to affect infertility and its treatment. The present study was to investigate the relationship between sleep disturbances and IVF outcomes in infertile women.MethodsDatabases, including PubMed, Embase, Cochrane Library, ProQuest, and Web of Science, were searched for the relevant articles published up to September 2023. The Newcastle–Ottawa Scale was used to assess the methodological quality of the included studies. Moreover, the random and fixed effects models using the STATA (v.11) software program presented the odds ratio with a 95% confidence interval (CI). Ultimately, a funnel plot was recruited to examine the sensitivity analysis.ResultsDuring the initial search, 426 articles were retrieved, and ultimately, nine studies remained for systematic review, and among them, four studies entered into the meta‐analysis (two cohort and two cross‐sectional studies). According to the fixed effects model of the cross‐sectional studies, the association between sleep quality and pregnancy rate was not confirmed (OR = 0.94; 95% CI = 0.81–1.07). Regarding the fixed effects model of included cohort studies, the results indicated an association between sleep quality and the pregnancy rate (OR = 1.08; 95% CI = 1.03–1.14). According to the random effects model of the cross‐sectional studies, there was no significant association between sleep quality and pregnancy rate (OR = 0.82; 95% CI = 0.37–1.26). Regarding the random effect analysis of included cohort studies, the results indicated an association between sleep quality and the pregnancy rate (OR = 1.08; 95% CI = 1.03–1.14). Based on the total fixed effect analysis of the cross‐sectional and cohort studies, the results also showed a significant association between sleep quality and pregnancy rate among infertile women (OR = 1.06; 95% CI = 1.01–1.11). In contrast, according to the random effect of the total studies, this association was not confirmed (OR = 1.02; 95% CI = 0.90–1.14).ConclusionAlthough the meta‐analysis of the cohort studies showed a significant association between sleep quality and IVF outcomes, such as pregnancy rate, due to the novelty of the subject, more studies have not been published, and this study is considered a preliminary meta‐analysis. Therefore, more studies with a strong methodology need to assess the relationship between sleep disorders and IVF outcomes.

ABSTRACTIntroductionPrevious observational studies have implied a correlation between cognitive impairment and dysphagia, but some have indicated no correlation between the two. Such contradictory findings may have been influenced by small sample sizes and potential confounders. In this Mendelian randomization (MR) analysis, we genetically estimated a causal relationship between cognitive impairment and dysphagia.MethodsThe study included a large meta‐analysis of genome‐wide association studies (GWAS) of cognitive impairment in 269,867 individuals of European ancestry and pooled data from a GWAS of dysphagia in 165,765 individuals of European ancestry (cases 3497, controls 161,968). We then used five different complementary MR methods, including IVW, MR‐Egger, MR‐RAPS, weighted median, and weighted mean, to estimate causality between cognitive impairment and dysphagia and finally also assessed heterogeneity and horizontal pleiotropy by extensive sensitivity tests.ResultsNo evidence of heterogeneity in the effect of instrumental variables was found in Cochran's Q test; therefore, a fixed effects model was used. IVW analysis (OR: 1.206, 95% CI: [1.041, 1.371], p = 0.00508) found that cognitive impairment was associated with an increased risk of dysphagia and that there was a causal association between the two. Also, the weighted median (OR: 1.248, 95% CI: [1.012, 1.484], p = 0.0253), weighted mode (OR: 1.216, 95% CI: [1.043, 1.389], p = 0.0412), and MR‐RAPS (OR: 1.225, 95% CI: [1.069, 1.381], p = 0.00627) validated the conclusions. Furthermore, extensive sensitivity analyses found no evidence of heterogeneity or horizontal pleiotropy, confirming the reliability of this MR result.ConclusionOur MR study demonstrated a causal effect of cognitive impairment on dysphagia from a genetic perspective, suggesting that individuals with a history of cognitive impairment require specific clinical attention to prevent the development of dysphagia.
