AbstractOne of the most unique properties of two‐dimensional carbides and nitrides of transition metals (MXenes) is their excellent water dispersibility and yet possessing superior electrical conductivity but their industrial‐scale application is limited by their costly chemical synthesis methods. In this work, the niche feature of MXenes was capitalized in the packed‐bed electrochemical reactor to produce MXenes at an unprecedented reaction rate and yield with minimal chemical waste. A simple NH4F solution was employed as the green electrolyte, which could be used repeatedly without any loss in its efficacy. Surprisingly, both fluoride and ammonium were found to play critical roles in the electrochemical etching, functionalization, and expansion of the layered parent materials (MAXs) through which the liberation of ammonia gas was observed. The electrochemically produced MXenes with excellent conductivity, applied as supercapacitor electrodes, could deliver an ultrahigh volumetric capacity (1408 F cm−3) and a volumetric energy density (75.8 Wh L−1). This revolutionary green, energy‐efficient, and scalable electrochemical route will not only pave the way for industrial‐scale production of MXenes but also open up a myriad of versatile electrochemical modifications for improved functional MXenes.

AbstractA simple method was proposed to activate alkaline Cu(OH)2 with an acidic ionomer, Nafion, to regulate its surface microenvironment, including hydrophobicity and local basicity. In particular, the direct complete neutralization reaction between Cu(OH)2 and Nafion in aqueous solution induces the exposing of vast anions which can exclude the in‐situ‐formed hydroxides and raise the local basicity. Remarkably, the optimal Nafion‐activated Cu(OH)2‐derived Cu can efficiently suppress the hydrogen evolution reaction (HER) and improve the selectivity for multi‐carbon products in the CO2 electroreduction reaction (eCO2RR). The H2 Faradaic efficiency (FE) decreased to 11% at a current density of 300 mA/cm2 (−0.76 V vs. RHE) in a flow cell, while the bare one with H2 had an FE of 40%. The total eCO2RR FE reaches as high as 83%, along with an evidently increased C2H4 FE of 44% as compared with the bare one (24%), and good stability (8000 s), surpassing that of most of the reported Cu(OH)2‐derived Cu. The experimental and theoretical results both show that the strong hydrophobicity and high local basicity jointly boosted the eCO2RR as acquired by felicitously introducing ionomer on the Cu(OH)2‐derived Cu surface.
Photochemistry Driven by Excited‐State Aromaticity Gain or Antiaromaticity Relief

Published: January 2023

AbstractGain of aromaticity or relief of antiaromaticity along a reaction path are important factors to consider in mechanism studies. Analysis of such changes along potential energy surfaces has historically focused on reactions in the electronic ground state (S0), but can also be used for excited states. In the lowest ππ* states, the electron counts for aromaticity and antiaromaticity follow Baird's rule where 4n π‐electrons indicate aromaticity and 4n+2 π‐electrons antiaromaticity. Yet, there are also cases where Hückel's rule plays a role in the excited state. The electron count reversals of Baird's rule compared to Hückel's rule explain many altered physicochemical properties upon excitation of (hetero)annulene derivatives. Here we illustrate how the gain of excited‐state aromaticity (ESA) and relief of excited‐state antiaromaticity (ESAA) have an impact on photoreactivity and photostability. Emphasis is placed on recent findings supported by the results of quantum chemical calculations, and photoreactions in a wide variety of areas are covered.

Published: January 2023

AbstractDual‐emissive photoconvertible fluorophores (DPCFs) are powerful tools to unambiguously track labeled cells in bioimaging. We recently introduced a new rational mechanism called directed photooxidation‐induced conversion (DPIC) enabling efficient DPCFs to be obtained by conjugating a coumarin to aromatic singlet‐oxygen reactive moieties (ASORMs). Pyrrole was found to be a suitable ASORM as it provided a high hypsochromic shift along with a fast and efficient conversion. By synthesizing various pyrrole‐based styryl coumarin dyes, we showed that the photoconversion properties, including the quantum yield of photoconversion and the chemical yield of conversion can be tuned by chemical modification of the pyrrole. These modifications led to an improved dual emissive converter, SCP−Boc, which displayed a high brightness and an enhanced photoconversion yield of 63 %. SCP−Boc was successfully used to sequentially photoconvert cells by laser scanning confocal microscopy.

Comprehensive SummaryThe instability of perovskite materials under continuous ultraviolet (UV) light irradiation and high sensitivity in humid environments remain obstacles to future commercialization. Especially, the photovoltaic performance of perovskite solar cells (PVSCs) is prone to decline under UV light exposure for sustained periods of time. However, in conventional methods, preventing UV light from entering PVSCs usually comes at the expense of reducing short circuit photocurrent (Jsc). Herein, the UV stability of PVSCs is modified by introducing a singlet fission down‐conversion layer 6,13‐bis(triisopropylsilylethynyl) pentacene (TIPS‐PEN) via one‐step anti‐solvent method without sacrificing device efficiency. The introduction of down conversion layer can not only improve the Jsc by converting UV light into multiple excitons, but also enhance the open‐circuit voltage (Voc) owing to a better matched energy level alignment at the perovskite/spiro‐OMeTAD interface. Consequently, the TIPS‐PEN incorporated PVSCs attain the champion power conversion efficiency (PCE) up to 22.92% accompanied with dramatically increased UV photostability which can retain 80% of its primitive PCE under continuous UV light soaking for 150 h. Moreover, the unencapsulated PVSCs with TIPS‐PEN exhibit remarkable moisture stability which can sustain over 80% of the initial value under air conditions (50% relative humidity, 25 °C) after 1000 h.

Comprehensive SummaryDeep ultraviolet (UV) photodetectors have important applications in the industrial and military fields. However, little research has been reported on organic phototransistors (OPTs) in the deep ultraviolet range. Here, a novel organic semiconductor containing a small torsion angle and low π‐conjugation 2,2':5',2”‐terthiophene groups, oF‐PTTTP, is designed and synthesized, which exhibits high carrier mobility and unique deep ultraviolet response. Accordingly, an OPT based on oF‐PTTTP single crystal shows high responsivity to deep‐UV light. The photodetectors achieve high photoresponsivity (R) of 857 A/W and detectivity (D*) of 3.2×1015 Jones under 280 nm light illumination (only 95 nW·cm–2). To the best of our knowledge, 280 nm is the deepest detection wavelength reported for organic phototransistors and this work presents a new molecule design concept for organic phototransistors with deep‐UV detection.

In 2019, different strains of the coronavirus have emerged drastically, that as severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) which is the causative agent of corona disease. As far as human civilization history, there have been occurrences of severe diseases and outbreaks of various viruses. According to World Health Organization reports, throughout the world, the present outbreak of COVID‐19 has engulfed more than 200 countries affecting 241,471,559 individuals and more than 4,914,092 people lost their lives. SARS‐CoV‐2 outbreak is severely disturbing the worldwide economy at present. The urgent need of recent times is to understand the environmental aspect of COVID‐19 disease. Hence to fulfill this point, the present review article is compiled with a brief discussion about all the minute points of the COVID‐19 pandemic related to the environment: origin and present scenario, the occurrence of SARS‐CoV‐2 in environmental habitats, the effect of COVID‐19 on human health, and environment, environmental factors influencing the transmission and spreading of SARS‐CoV‐2. This review explains micro and macro pollutants in hospital and urban wastewater influencing COVID‐19, detection of SARS‐CoV‐2, current global drug strategies to control replication and spread of SARS‐CoV‐2 from the environment, future approaches, and guidelines to prevent and control upcoming pandemics. The SARS‐CoV‐2 structural details and their effect on humans have been already well presented but the research about environmental factors affecting COVID‐19 could be important points to fight present and future pandemics.

AbstractInorganic perovskite CaMnO
was proposed as a substitution for the TiO

NH
PbI
based on increased mobility of electrons and better optical matching. Due to a suitable band gap concerning the absorption of sunlight, we investigate the potential of CaMnO
and similar manganite perovskites, where Ca is replaced by either Sr, Ba or La, as an absorber layer in inorganic perovskite solar cells. In this study, we have used optical measurements on the synthesized AMnO
(A=Ca, Sr, Ba, La) samples to aid density functional theory calculations (DFT) in order to accurately simulate the electronic and optical properties of AMnO
compounds and gauge their potential for the role of absorber layer. Both experimental measurements and theoretical calculations show suitable band gap of 1.1‐1.5 eV, depending on the compound, and absorption coefficients of the order of
cm
in the visible part of the spectrum.

Published: January 2023

AbstractObjectivesThe purpose of this systematic review (SR) was to present the current state of research on historical trauma, and the topics closely related to its semantic space that include intergenerational trauma, collective trauma, and extended cultural bodily and mental responses, in order to identify gaps in the literature that need to be addressed.MethodsA search of empirical studies from 1990 to 2022 was performed via Scopus, Web of Science, MEDLINE, EBSCOhost‐PsychInfo, and Embase, following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) checklist.ResultsThe initial search yielded 1012 studies, 52 of which were included in the current review. The results show that the historical trauma concept has a high potential for new research in the field of Global Mental Health. Gaps in the literature were identified, including a lack of standard features of historical trauma, and assessments of historical trauma in additional contexts than its original fields of application with Indigenous Americans.ConclusionAlthough the introduction of the concept of historical trauma was intended to fill the gap of trauma‐related difficulties not covered by the criteria of post‐traumatic stress disorder (PTSD), this concept needs further scientific refinement.

Tectonic geomorphology and Quaternary fault slip rates in the Tsambagarav Massif, Mongolian Altai
Authors: Ha Sangmin , Seong Yeong Bae , Son Moon 
Published: January 2023

AbstractThe NNW‐striking Mongolian Altai is a Late Cenozoic dextral strike–slip deformation belt affected by the far‐field stress caused by the collision between India and Eurasia. The Tsambagarav Massif is bounded by faults, has a triangular plan shape, and attains the highest elevation of the belt. This massif is adjacent to the central segment of the Hovd fault, which is the largest fault in the Mongolian Altai. Here, we use 10Be surface exposure dating, radiocarbon dating, and paleoseismic trenching to reveal deformation patterns and Quaternary slip rates for two range‐bounding faults: the Tsambagarav dextral reverse fault and the Lower thrust fault. The Lower thrust exhibits thrusting motion along the low‐angle structural fabric of the basement rock and cuts Quaternary alluvial fan deposits, vertically offsetting their surfaces by 3.9–5.1 m, with fault scarps extending several kilometres along‐strike. The Tsambagarav dextral reverse fault is characterized by strike–slip motion along the high‐angle structural fabric of basement rock. Various surface deformation features indicate recent dextral strike–slip, including displacements of Late Quaternary moraine by ~50 m. Dividing the measured displacements by 10Be surface exposure ages of alluvial fan surfaces (for the Lower thrust) and moraine (for the Tsambagarav dextral reverse fault) gives a reverse slip rate of 0.3–1.7 mm/yr for the Lower thrust and a horizontal slip rate of 1.7–2.6 mm/yr for the dextral reverse fault. Radiocarbon ages of animal bones in a pond deposit accumulated along an associated tensional crack indicate that the last earthquake that caused a surface rupture occurred between 1924 and 1708 cal yr BP. Our study suggests that strain partitioning has occurred on the faults of the Tsambagarav Massif.

Published: January 2023

AbstractThe basic idea of this article is to investigate the numerical solutions of Gardner Kawahara equation, a particular case of extended Korteweg‐de Vries equation, by means of finite element method. For this purpose, a collocation finite element method based on trigonometric quintic B‐spline basis functions is presented. The standard finite difference method is used to discretize time derivative and Crank–Nicolson approach is used to obtain more accurate numerical results. Then, von Neumann stability analysis is performed for the numerical scheme obtained using collocation finite element method. Several numerical examples are presented and discussed to exhibit the feasibility and capability of the finite element method and trigonometric B‐spline basis functions. More specifically, the error norms and are reported for numerous time and space discretization values in tables. Graphical representations of the solutions describing motion of wave are presented.
Comparative studies on performance of plain, perforated, threaded, and threaded–perforated pin fin: A numerical approach

Published: January 2023

AbstractA heat sink is a thermal management system for electrical and electronic appliances whose performance is a function of fin geometry, arrangement, and flow field. Earlier research addressed the enhancement in the heat dissipation capacity of the sink with a change in the geometry of the fin. However, the change should increase the heat transfer rate per unit weight and per unit volume. One such attempt is made in the present work, which deals with numerical forced convection heat transfer simulation over a pin fin with three different surface modifications, namely, threads, equilateral triangular perforation, and threads with perforations. A numerical investigation is performed for 0.5773–2.5574 mm pitch of threads, 3–4.8 mm size of perforation, and 2–8 m/s velocities of air. To describe the flow pattern around the fin and its variation with surface modification, streamline profiles are drawn which reveals that the fluid–solid interaction is improved either with threaded or perforated surface and is maximum for threaded–perforated fin. The enhanced convection rates bring down the local fin temperature and the maximum fin temperature, where the drop is more for the threaded surface than that of the perforated surface because of turbulence. A 10° drop in maximum fin temperature is achieved by replacing a plain pin fin with a threaded–perforated pin fin, and the drop is 8° with threads alone and 6° only with perforations. The increased fineness of threads and size of perforation further bring down the maximum fin temperature.
The emerging mechanism behind viral infections and extracellular vesicles hypotheses leading to neuroinflammation and Alzheimer's disease pathology
Authors: Anwar Mai M. 
Published: January 2023

AbstractDespite decades of repeated and intense research, the etiology of sudden Alzheimer's disease (AD) symptoms is still unclear. AD progressive pathology mainly involves neuron damage, depositions of amyloid‐beta (Aβ), and hyperphosphorylated tau protein. All these defects are manifested by exaggerated cytokine storm and neuroinflammation leading to irreversible brain damage in the long term. Despite the numerous risks and drawbacks associated with AD, it is believed that there is a hidden unknown causative and predisposing factors for AD. Extracellular vesicles (EVs) are small vesicles released by cells as a type of intercellular communication. Several pieces of evidence support the inclusion of viral components within EVs facilitating their penetration into the blood–brain barrier leading to neuroinflammation. In light of the SARS‐CoV‐19 pandemic and its related neurological complications, it is mandatory to highlight the possibility and viability of viral infections such as varicella‐zoster virus (VZV) and herpes simplex virus (HSV) on the onset of AD. Herein, the author is investigating the potential role of VZV and HSV along with highlighting the suggested route of pathogenesis entry resulting in AD manifestations. Additionally, this review aims to summarize the role of EVs in mediating the central nervous system viral infections leading to AD.
Additive and synergistic relations of early mother–child and caregiver–child interactions and socioeconomic outcomes in adulthood

Published: January 2023

AbstractPrior theoretical and empirical studies have linked the first 3 years of children's life with later life outcomes. One primary explanation is the critical role these experiences play in children's early brain development (including their early language and cognitive abilities) and subsequent schooling achievement. The current study is a registered report with two complementary research objectives: (1) examine to what extent stimulating and responsive interactions with mothers and nonparental caregivers during the first 3 years of life show additive or synergistic associations with key socioeconomic outcomes in adulthood (i.e., educational attainment, salary, and employment status), and (2) examine to what extent academic skills (i.e., mathematics, vocabulary, and literacy) during childhood and adolescence mediate these associations. The sample included 1364 individuals from a birth cohort study who were followed until age 26. Mother–child interactions had positive associations with educational attainment and negative associations with full‐time employment, though no synergistic associations were found for the socioeconomic outcomes. In addition, the indirect effects of mother–child interactions on educational attainment through mathematics were strongest for children with less stimulating and responsive caregiver–child interactions. Potential implications of these findings for developmental theory are discussed.
Economic policy uncertainty nexus with the value relevance of advertising: Evidence from an emerging market
Authors: Jabbouri Imad , Farooq Omar , Jabbouri Rachid 
Published: January 2023

AbstractThis paper aims to document the effect of economic policy uncertainty on the value of advertising expenditures within the context of an emerging market. The paper shows that the value of advertising expenditures is an increasing function of economic policy uncertainty. The impact of advertising on firm performance is more pronounced during the periods characterized by higher economic policy uncertainty. We argue that, during uncertain times, the financial information loses its relevance. Therefore, during these periods, non‐financial traits, such as brand image, customer equity, relationship capital, and familiarity that characterizes firms with high advertising become more important. The findings hold in various sub‐samples and across various proxies of advertising activity. The findings also hold under alternate estimation procedures (pooled OLS regression, panel data with fixed effects and instrument variable regression). More importantly, this paper also shows that, relative to other agency reducing mechanisms (such as analyst coverage, asset utilization ratio, expense ratio and dividend payments), advertising is more valuable during periods with high economic policy uncertainty.

Published: January 2023

AbstractEcological validity refers to how closely an experiment aligns with real‐world phenomena. In applied behavioral research, ecological validity may guide decisions about experimental settings, stimuli, people, and other design features. However, inconsistent use of the term ecological validity in the published literature has led to a somewhat disjointed technology. The purposes of this paper were to review current uses of the term “ecological validity” in the Journal of Applied Behavior Analysis, propose ways to make a study more ecologically valid, and develop a checklist to assist in identifying the type and degree of ecological validity in any given study.
