Authors: Shiragami Tsutomu , Nabeshima Keiko , Yasuda Masahide , Inoue Haruo 
Published: January 2003

Abstract
Adsorption and intercalation of +1 charged cationic dihydroxo(tetraphenylporphyrinato)antimony(V) bromide (1a) into an artificially synthesized smectite clay was studied. The red shift of Soret band of 1a was observed in an aqueous clay suspension owing to the adsorption onto the clay. Analyses of X-ray diffraction of the obtained complex between 1a and the clay indicate the intercalation of 1a into the clay interlayer. Hydroxo group as an axial ligand led to the effective intercalation of 1a into the clay.

AbstractProtonic ceramic fuel cells (PCFCs) are one of the promising routes to generate power efficiently from various fuels at economically viable temperatures (500–700 °C) due to the use of fast proton conducting oxides as electrolytes. However, the power density and durability of the PCFCs are still limited by their cathodes made from solid metal oxides, which are challenging to address the sluggish oxygen reduction reaction and susceptibility to CO2 simultaneously. Here, an alternative approach is reported to address this challenge by developing a new melt‐solid interface through the in situ alkali metal surface segregation and consecutive eutectic formation at perovskite oxide surface at PCFC operating temperatures. This new approach in cathode engineering is successfully demonstrated over lithium and sodium co‐doped BaCo0.4Fe0.4Zr0.1Y0.1O3‐δ perovskite as the model material. These experimental results unveil that the unique in situ formed melt‐solid surface stabilizes the catalytically active phase in bulk and promotes catalytically active sites at surface. The novel engineered melt‐solid interface enhances the stability of the cathode against poisoning in 10% CO2 by a factor of 1.5 in a symmetrical cell configuration and by a factor of more than two in PCFC single cells.

AbstractThermally induced tensile strain that remains in perovskite films after annealing is one of the key reasons for diminishing the performance and operational stability of perovskite solar cells (PSCs). Herein, a glass transition temperature (Tg) regulation (TR) strategy is developed by introducing two polymerizable monomers, 2‐(N‐3‐Sulfopropyl‐N,N‐dimethyl ammonium)ethyl methacrylate (SBMA) and 2‐Hydroxyethyl acrylate (HEA), into the perovskite layer. SBMA and HEA undergo in situ polymerization, which regulates the nucleation and crystal growth of the perovskite film. In addition, adjusting the ratio of SBMA and HEA to lower the Tg of the resulting polymer effectively releases the strain in the perovskite film. The modified film exhibits significantly reduced tensile strain, decreased trap density and improved stability. As a result, the optimized PSCs achieve a champion power conversion efficiency (PCE) of 26.15% (certified as 25.59%). Furthermore, the encapsulated device demonstrates prominent enhanced operation stability, maintaining 90.3% of its initial efficiency after 500 h of continuous sunlight exposure.
Study of Supercooled Water Drop Impact on Icephobic Gradient Polymer Coatings

Published: February 2025

AbstractSupercooled liquid water drops, with temperatures below freezing point, are common in high‐altitude clouds. These drops, despite being in a metastable state, can remain liquid for extended periods if temperatures are above the homogeneous nucleation point. Impact of such liquid drops with a cold solid surface is one of the reasons for ice accretion, which in many cases can represent a safety hazard. The study of supercooled drop impact dynamics is key to developing materials that provide resistance against the formation and accumulation of ice. In this work, the impact of supercooled water drops on dry icephobic coatings based on gradient polymers deposited via initiated chemical vapor deposition (iCVD) under several conditions is analyzed. Experimental results show that coated surfaces potentially decrease the freezing probability upon impact. The gradient polymer surfaces with higher roughness and lower wettability do not increase the freezing probability upon impact but result in rebound and eventual roll off the surface, indicating that surface hydrophobic properties prevailed over the impact. The findings demonstrate the remarkable efficacy of gradient polymer coatings in inhibiting drop freezing, even under high wind velocities, and provide insights for the design of durable and effective anti‐icing coatings across diverse applications.

Published: February 2025

ABSTRACTAmidst a recent surge in US goat meat imports to meet growing demand, this study contributes to the meat demand literature by examining consumer preferences for goat meat, a relatively healthy and environmentally friendly alternative to other popular meats. We employed a discrete choice experiment on representative US meat consumers and randomly assigned respondents to health and environmental information treatments. Further, information treatments were categorized into goat‐focused comparative and generic information treatments. Estimates from the random parameter logit model reveal that health information treatments outperform environmental information treatments in influencing consumer preferences for goat meat. Additionally, the results show that goat‐focused comparative information is more effective than generic information treatment. The market share simulations under different price scenarios suggest decreasing goat meat price to $4/lb. and informing respondents of the health benefits of goat meat over beef can yield up to 21% market share of the total US meat market for goat meat. These findings underscore the potential of goat meat in the US meat market, particularly when coupled with health information nudges.
Using K‐Means Clustering to Explore Farmers' Behavior and Intention Towards Online Credit in China Based on Extended Theory of Planned Behavior

Published: February 2025

ABSTRACTAlthough online credit is recognized as one of the promising approaches to solving the problem of difficult access to loans for Chinese farmers in theory, there is still actually a lack of enthusiasm among farmers for its adoption. This study is dedicated to exploring the reasons why farmers don't adopt online credit from the perspective of perceptions. Based on field survey data involving 698 farmers in Shaanxi province, six constructs derived from the extended theory of planned behavior are designed to identify the specific characteristic typologies of farmers’ online credit perceptions using the K‐means clustering method. Furthermore, the characteristics associated with farmers online credit behavior and intention are examined by an ordered logistic regression model. The results of cluster analysis reveal that five groups with differentiated perception characteristics are partitioned and labeled as (1) Socially influenced non‐believers, (2) Socially independent non‐believers, (3) Just see fraud skeptics/Socially independent skeptics, (4) Suspicious but socially influenced, and (5) Neutral independent and no distinctive perception. The results of ordered logistic regression show that distrust and suspicion among farmers towards online credit have significant relationships with shaping their behavior and intention. Concurrently, it cannot be overlooked the association between subjective norms and farmers’ online credit attitudes and perceptions. Additionally, farmers’ online credit behavior and intention also have correlations with various socio‐demographic factors, including gender, age, education, physical health condition, off‐farm work, and broadband coverage.
An improved theoretical model for eddy‐induced bubble breakup in turbulent flows

Published: February 2025

AbstractThis work aims on establishing an improved model for bubble breakup in turbulent flows. To achieve this goal, the impact of bubble shape on the critical size for distinguishing large and small eddies, cross‐sectional area of eddy‐bubble collision tube, energy increment breakage criterion, and force breakage criterion is deeply studied, and accurate formulas quantifying these effects are incorporated into the developed model. Moreover, a dimensionless number is proposed to overcome the limitation of the collision cube mechanism model which neglects the influence of bubble oscillation in the radial direction of the tube. The results indicate that the developed model exhibits high prediction accuracy with a mean absolute relative error (MARE) of 18.88% for the breakage frequency, and the predicted bubble size distribution aligns closely with experimental trends.

Published: February 2025

ABSTRACTAicardi‐Goutières syndrome (AGS) is a hereditary encephalopathy characterized by marked clinical variability, mainly cerebral calcifications, cerebral atrophy, and leukodystrophy. The clinical diagnosis is difficult and can lead to high mortality. To date, nine genes are implicated, including RNASEH2A, RNASEH2B, RNASEH2C, TREX1, SAMHD1, ADAR1, IFIH1, LSM11, and RNU7‐1. However, the p.A177T (c.529G>A) RNASEH2B gene mutation was described as the most recurrent mutation in several populations. Overall, there is a lack of research data on AGS in Morocco. Seven Moroccan patients from four families were referred for evaluation of Aicardi‐Goutières syndrome (AGS). The first patient, a 1.5‐year‐old boy with leukodystrophy, underwent exome sequencing. The remaining six patients (a 2.5‐year‐old boy, three sisters aged 14, 10, and 2, and two sisters aged 5 and 3, along with another 2.5‐year‐old boy) were tested for the recurrent p.A177T (c.529G>A) RNASEH2B gene mutation using polymerase chain reaction and Sanger sequencing. Of the seven patients, five (two unrelated and three siblings) were homozygous for this pathogenic variant. Symptoms ranged from isolated spasticity with brain calcification to typical encephalopathy, with an average onset age of 1.5 years. Clinical variability was observed within one family. These findings demonstrate the phenotypic diversity of AGS and indicate that the first step of the diagnostic strategy should be genetic testing for the p.A177T (c.529G>A) RNASEH2B recurrent mutation.

AbstractA FeCl3‐assisted electrophilic fluorine‐catalyzed 1,3‐rearrangement was developed, characterized by its mild catalytic system and broad substrate scope. The functional group tolerance of this approach was evaluated through a series of allylic alcohols readily prepared in situ from commercially available enones. Various nucleophiles, including water, amides, and Hantzsch esters, were utilized in the reaction. A plausible mechanism was proposed to elucidate the observed transformations, and the versatility of this methodology was demonstrated through the syntheses of asparenyn, gonicusin B, and the PPAR‐agonist NNC 61‐4655.

AbstractLi‐ and Mn‐rich layered oxides exhibit high specific capacity due to the cationic and anionic reaction process during high‐voltage cycling (≥4.6 V). However, they face challenges such as low initial coulombic efficiency (~70 %) and poor cycling stability. Here, we propose a combination of H3BO3 treatment and low temperature calcination to construct a shell with cationic vacancy on the surface of Li1.2Ni0.2Mn0.6O2 (LLNMO). The H3BO3 treatment produces cationic vacancy and lattice distortion, forming an oxidized On− (0<n<2) on the surface, accompanied by electrons redistribution. Low temperature calcination eliminates lattice distortion, activates metastable On− and promotes coherent lattice formation. In addition, the cationic vacancy shell reduces the diffusion energy barrier of Li+, allowing more Li+ and oxygen to participate in deeper reactions and increasing the oxidation depth of oxygen. The modified material (LLNMO‐H10‐200) exhibits an initial coulombic efficiency of up to 88 % and a capacity of 256 mAh g−1. Moreover, similar enhancements were observed with Co‐containing lithium‐rich materials, with a 280 mAh g−1 discharge capacity and 89 % coulombic efficiency. These findings reveal the correlation between cationic vacancy, metastable oxygen activation and bulk phase activity, offering a novel approach to enhancing the initial coulombic efficiency and cycle stability of Li‐rich materials.

AbstractINTRODUCTIONOlder adults lose billions of dollars to financial exploitation (FE) annually. It has been described as a “burgeoning public health crisis” and “virtual epidemic.” This study evaluated a conceptual framework investigating early memory loss and personal financial behaviors and their association with financial exploitation and financial exploitation vulnerability.METHODSThe study used a cross‐sectional design and included 150 participants, with t‐tests and chi‐squared tests being used in bivariate analysis and logistic and multiple regressions being used in multivariate analysis.RESULTSEarly memory loss was related to financial exploitation and financial exploitation vulnerability in univariate analysis. However, early memory loss was only related to financial exploitation vulnerability in multivariate analysis. Personal financial behaviors also showed significant associations with financial exploitation and financial exploitation vulnerability in multivariate analysis.DISCUSSIONResults support the proposed framework that early memory loss and personal financial behaviors share a relationship with financial exploitation and financial exploitation vulnerability.

Published: February 2025

ABSTRACTThe study explores the relationships between green branding practices (GBP) and consumer behavior, aiming to extend knowledge on the interaction between green branding and purchase decisions. The research involved 521 students from the University of Prishtina using stratified random sampling. Data analysis employed SmartPLS to examine the relationships within the model. The study found significant relationships between green positioning and consumer attitudes, green packaging's influence on purchasing behavior, and the impact of brand commitment on green purchase decisions. In contrast, the hypothesis linking brand attachment, green brand trust, and green brand equity to green purchase decisions was rejected. The findings suggest that green branding can be a competitive advantage by aligning with growing consumer preferences for environmentally responsible products. This study highlights the importance of sustainable brand strategies and advocates for authentic environmental initiatives in marketing communications.

Published: February 2025

ABSTRACTAtherosclerosis is driven by the expansion of cholesterol‐loaded foamy macrophages in the arterial intima. Single‐cell RNA sequencing has recently revealed the transcriptional landscape of macrophages in these atherosclerotic plaques and uncovered a population of foamy cell‐like myeloid cells expressing triggering receptor expressed on myeloid cells‐2 (TREM2)—TREM2hi macrophages. Fundamental research has brought essential insight into the significance of TREM2 for foam macrophage survival and atherosclerosis progression, making TREM2 as a therapeutic target in atherosclerosis possible. This review retraces TREM2's winding route from pure knowledge to therapeutic interventions, as well as the potential feasibility of its clinical application for atherosclerosis.

Published: February 2025

ABSTRACTIncomplete Miller‐Fisher syndrome (MFS) is a rare autoimmune disorder affecting the nervous system. In contrast to classical MFS, its clinical manifestations are often atypical and may be characterized by the absence of certain features, such as extraocular muscle paralysis and the loss of tendon reflexes. The presence of anti‐GD3 antibodies is infrequently observed in these patients. This case report describes a patient diagnosed with incomplete MFS who exhibited positive anti‐GD3 antibody results and presented with pyramidal tract signs. This suggests that anti‐GD3 antibodies may play a role in the pathogenesis of some atypical forms of MFS, warranting attention in clinical practice.

AbstractThis study reports on the synthesis, fluorescence modulation, and white‐light emission characteristics of a series of isostructural lanthanide‐based metal‐organic frameworks (Ln‐MOFs). The synthesized materials demonstrated exceptional color rendering capabilities, design flexibility, color tunability, and high fluorescence efficiencies. Through strategic doping, a range of mono‐ and co‐doped complexes were successfully obtained, enabling precise tuning of the fluorescence properties. An optimized white‐light‐emitting material was developed based on the additive color mixing principle of the three primary colors. The fluorescence attributes, including brightness, luminescence lifetime, quantum yield, and color purity, were comprehensively evaluated. Furthermore, the complexes exhibited notable fluorescence quenching effects in response to Cd2+ ions, highlighting their potential as sensors for the detection of cadmium ions in complex metal ion solutions. This research offers valuable insights into the advancement of Ln‐MOFs for applications in white‐light emission and fluorescence‐based sensing.
