AbstractIntroductionPrior estimates of dementia prevalence in India were based on samples from selected communities, inadequately representing the national and state populations.MethodsFrom the Longitudinal Aging Study in India (LASI) we recruited a sample of adults ages 60+ and administered a rich battery of neuropsychological tests and an informant interview in 2018 through 2020. We obtained a clinical consensus rating of dementia status for a subsample (N = 2528), fitted a logistic model for dementia status on this subsample, and then imputed dementia status for all other LASI respondents aged 60+ (N = 28,949).ResultsThe estimated dementia prevalence for adults ages 60+ in India is 7.4%, with significant age and education gradients, sex and urban/rural differences, and cross‐state variation.DiscussionAn estimated 8.8 million Indians older than 60 years have dementia. The burden of dementia cases is unevenly distributed across states and subpopulations and may therefore require different levels of local planning and support.Highlights
The estimated dementia prevalence for adults ages 60+ in India is 7.4%.
About 8.8 million Indians older than 60 years live with dementia.
Dementia is more prevalent among females than males and in rural than urban areas.
Significant cross‐state variation exists in dementia prevalence.

Published: January 2023

AbstractCrystallography modulation of zinc (Zn) metal anode is promising to promote Zn reversibility in aqueous electrolytes, but efficiently constructing Zn with specific crystallographic texture remains challenging. Herein, we report a current‐controlled electrodeposition strategy to texture the Zn electrodeposits in conventional aqueous electrolytes. Using the electrolytic cell with low‐cost Zn(CH3COO)2electrolyte and Cu substrate as a model system, the texture of as‐deposited Zn gradually transforms from (101) to (002) crystal plane as increasing the current density from 20 to 80 mA cm−2. Moreover, the high current accelerates the Zn nucleation rate with abundant nuclei, enabling uniform deposition. The (002) texture permits stronger resistance to dendrite growth and interfacial side reactions than the (101) texture. The resultant (002)‐textured Zn electrode achieves deep cycling stability and supports the stable operation of full batteries with conventional V/Mn‐based oxide cathodes.

Published: January 2023

AbstractA biodegradable silica was fabricated to achieve effective tumor microenvironment responsive drug delivery with low drug leakage (4%, 80 h) and good biosafety. A disulfide bond embedded copolymer composited by methylacrylic acid (MAA) and vinyl trimethoxysilane was utilized for the in situ synthesis of the PMAA hybrid biodegradable silica shell. The biodegradable silica was introduced as a gatekeeper to alter the drug release behavior of the doxorubicin‐loaded in the mesoporous silica microspheres. The fabrication process and glutathione‐responsive degradation of the drug delivery system were carefully studied. In vitro drug release experiments revealed that 65% of the loaded drug could be released after 80 h in simulated tumor environment. The biocompatibility of the carrier and the anti‐cancer efficiency against the HepG2 cancer cell line were studied with the cell counting kit‐8 assay. The method to prepare the biodegradable silica reported in this work might provide new thought to the fabrication of high‐performance drug delivery systems.

Published: January 2023

AbstractThe difluoromethylthio group (SCF2H), which is generally considered a highly lipophilic weak hydrogen bonding donor, has attracted special interest from the pharmaceutical and agrochemical industry. Remarkably, there have been relatively few literature investigations of SCF2H hydrogen bonding interactions. Here, we report the determination of the hydrogen bond acidity parameter A of the SCF2H in the most popularly used electrophilic difluoromethylthiolating reagent. We present kinetic and computational evidence of the RSCF2−H⋅⋅⋅O2 bifurcated hydrogen bond for stabilizing the SCF2H‐transferring transition state, which could cause a reversal of apparent electrophilic reactivity of difluoromethylthiolating and trifluoromethylthiolating reagents. Solvent effects on the RSCF2−H⋅⋅⋅O2 bifurcated hydrogen bonds will also be discussed.

Published: January 2023

AbstractSulfide‐based all‐solid‐state lithium‐ion batteries (LIBs) are promising replacements for conventional liquid electrolyte LIBs. However, their degradation mechanisms and analysis methods are poorly understood. Herein, the degradation mechanism of an argyrodite‐type sulfide‐based all‐solid‐state prototype LIB cell is reported. Furthermore, an analysis method for all‐solid‐state batteries using charge/discharge cycle tests at 100°C followed by the disassembly analysis of cells before and after accelerated degradation tests is reported. Based on the findings of this study, the degradation of the prototype cell is classified as follows: (i) solid electrolyte (SE) oxidation in the positive electrode, which recovers battery capacity and increases resistance; (ii) SE reduction in the negative electrode, which decreases capacity; (iii) lithium deposition on/in the negative electrode, which decreases capacity; and (iv) capacity loss of the positive electrode, which decreases capacity. These degradation reactions appear to occur simultaneously. These findings are expected to aid the development of sulfide‐based solid‐electrolyte LIBs with improved safety and energy densities.

Authors: Neeraj Manjappatta Pazhiyottumana , Maniyeri Ranjith 
Published: January 2023

AbstractThe current work deals with the simulation of lateral migration of differently shaped particles in a straight channel through which fluid flows with a Poiseuille pattern of flow. The immersed boundary method based on feedback force is adopted for the current work. The equilibrium positions and migration times for circular, elliptical, rectangular, square, and biconcave particles are studied and presented. The cases of neutral and massive (high ratio of particle density to fluid density) particles are presented, and in both scenarios the biconcave particle attains its equilibrium position closest to the bottom wall and the elliptical particle acquires its equilibrium position closest to the channel center. Also, the migration time is highest for the biconcave particle, whereas it is lowest for the rectangular particle.
Azo Appended Modified Lawsone Derived Ru‐Systems with Multi‐Redox Entities. Competitive Electronic Form and the Question of Azo Reduction

AbstractThe article dealt with the ruthenium complexes of redox active azo appended modified lawsone L1− (HL1: (E)‐2‐hydroxy‐3‐(p‐tolyldiazenyl)naphthalene‐1,4‐dione))/L2− (HL2:5‐hydroxy‐6‐p‐tolylazobenzo[a]phenazine) derived [RuIII(acac)2(L1−)]/[RuIII(acac)2(L2−)] 1/5, [RuII(bpy)2(L1−)]ClO4/[RuII(bpy)2(L2−)]ClO4 [2]ClO4/[6]ClO4, ctc‐[RuII(pap)2(L1−)]ClO4/ctc‐[RuII(pap)2(L2−)]ClO4 [3]ClO4/[7]ClO4 and [RuII(CO)(H)(PPh3)2 (L1−)]/[RuII(CO)(Cl)(PPh3)2(L2−)] 4/8 (acac=acetylacetonate, bpy=2,2′‐bipyridine, pap=2‐phenylazopyridine). The ligands L1− and L2− differed with respect to the para‐quinone versus phenazine moieties linked to the azo function. Structural analysis of the complexes established unreduced state of the azo (N=N) group of coordinated L1−/L2− or pap as well as unprecedented para‐quinone form of L1−. The involvement of selective redox center(s) towards the accessible redox steps of the complexes encompassing multiple redox active entities i. e. Ru, phenolate (L1−/L2−), para‐quinone (L1−), phenazine (L2−), azo (L1−/L2−, pap), diimine (bpy) was analyzed by combined experimental and DFT calculations. It revealed that under the prevailing competitive scenario oxidation was mostly dominated by the phenolate group of L1−/L2− (phenolate→phenoxide), while successive reductions were taken place either at the para‐quinone/phenazine units of L1−/L2− or azo/diimine functions of pap/bpy. Though the azo function of pap in 3+/7+ underwent facile reduction, the same azo function associated with L1−/L2− conspicuously remained unreduced in all occasions. The frontier molecular orbital analysis revealed that the propensity of pap for the azo reduction with special reference to that in L1−/L2− could be correlated with its relatively lower energy π* orbital (LUMO). Complexes displayed intense LMCT (1/5) and bpy (2+/6+), pap (3+/7+), L (4/8) targeted MLCT transitions in the visible region.
Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation

Published: January 2023

SummaryThermally activated atomic vibrations significantly decrease the x‐ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals by x‐ray diffraction. In this study, atomic vibrations in the form of mean square displacements (MSDs) in 5, 10, 15, 20, and 30 nm diameter spherical gold nanocrystals were computed by molecular dynamics (MD) simulations at room temperature and below. A strong size and temperature dependency of MSD was observed from spherical gold nanocrystals. Moreover, these displacements increased radially from the center of the nanocrystals and reached a maximum at the surface layers due to the presence of undercoordinated surface atoms and their relatively unrestricted motions. High temperature simulations were performed to investigate the evolution of structural stability of nanoparticles with increasing temperature. Surface melting was observed before complete melting of nanocrystals. Results of this work will be useful to understand the effect of nanocrystal size on the amplitude of thermally activated atomic vibrations and their quantification in measured intensities by x‐ray diffraction experiments.
Turning Polyethylene Waste to Hydrocarbons Using a Sustainable Acidic Carbocatalyst
Authors: Al‐Naji Majd , Antonietti Markus 
Published: January 2023

AbstractCareless release of plastic waste is a pressing problem for marine and other eco‐environments, and materials recycling of this stream is an open problem. For this purpose, a new metal‐free acidic carbocatalyst with 8 wt % sulfur is constructed from a side product of the paper industry namely Na‐lignosulfonate. The catalyst shows an extraordinary performance for the fragmentation of polymer waste which smoothly occurs above the ceiling temperature of the polymers. The reaction is run without hydrogen and at ambient pressure with commercially available high‐density polyethylene (HDPE) as well as a real polymer waste mixture of high and low‐density polyethylene (HDPE, LDPE). In all cases, a homologous series of n‐alkanes and n‐alkenes are obtained. The unique sulfur‐rich carbonaceous structure (transfer hydrogenation functionality) and the metal‐free character of the acidic carbocatalyst makes it inert against many typical catalyst poisons, among them water, salt, polar functionalities, and sulfur species. The described performance in plastic recycling, as well as the low cost and large‐scale availability of lignosulfonate from the pulp industry, makes this metal‐free acidic carbocatalyst promising for real‐life environmental applications.
Chronic nicotine exposure alters sperm small RNA content in C57BL/6J mouse model
Authors: Zeid Dana , Gould Thomas J. 
Published: January 2023

AbstractMultigenerational inheritance is a nongenomic form of heritability characterized by altered phenotypes in the first generation born from the exposed parent. Multigenerational factors may account for inconsistencies and gaps in heritable nicotine addiction vulnerability. Our lab previously found that F1 offspring of male C57BL/6J mice chronically exposed to nicotine exhibited altered hippocampus functioning and related learning, nicotine‐seeking, nicotine metabolism, and basal stress hormones. In an effort to identify germline mechanisms underlying these multigenerational phenotypes, the current study sequenced small RNA extracted from sperm of males chronically administered nicotine using our previously established exposure model. We identified 16 miRNAs whose expression in sperm was dysregulated by nicotine exposure. A literature review of previous research on these transcripts suggested an enrichment for regulation of psychological stress and learning. mRNAs predicted to be regulated by differentially expressed sperm small RNAs were further analyzed using exploratory enrichment analysis, which suggested potential modulation of pathways related to learning, estrogen signaling, and hepatic disease, among other findings. Overall, our findings point to links between nicotine‐exposed F0 sperm miRNA and altered F1 phenotypes in this multigenerational inheritance model, particularly F1 memory, stress, and nicotine metabolism. These findings provide a valuable foundation for future functional validation of these hypotheses and characterization of mechanisms underlying male‐line multigenerational inheritance.
Tuning static drop friction

AbstractThe friction force opposing the onset of motion of a drop on a solid surface is typically considered to be a material property for a fixed drop volume on a given surface. However, here we show that even for a fixed drop volume, the static friction force can be tuned by over 30% by preshaping the drop. The static friction usually exceeds the kinetic friction that the drop experiences when moving in a steady state. Both forces converge when the drop is prestretched in the direction of motion or when the drop shows low contact angle hysteresis. In contrast to static friction, kinetic friction is independent of preshaping the drop, that is, the drop history. Kinetic friction forces reflect the material properties.
Marbled cats in Southeast Asia: Are diurnal and semi‐arboreal felids at greater risk from human disturbances?

Published: January 2023

AbstractSoutheast Asia supports the greatest diversity of felids globally, but this diversity is threatened by the severe forest loss and degradation occurring in the region. The response of felids to disturbances appears to differ depending on their ecology. For example, the largely terrestrial and nocturnal leopard cat (Prionailurus bengalensis) thrives near forest edges and in oil palm plantations where it hunts rodents (Muridae) at night, thereby avoiding human activity peaks. Conversely, we hypothesized that the sympatric and similar‐sized marbled cat (Pardofelis marmorata) would respond negatively to edges and relatively open oil palm plantations as they are more arboreal than leopard cats, rely on tree connectivity for hunting, and are diurnal so have less potential to temporally avoid humans. We used camera trapping from Southeast Asia to test habitat associations at multiple spatial scales using zero‐inflated Poisson generalized linear mixed models and hierarchical occupancy modeling. We found that marbled cats were positively associated with large intact forests and, in contrast to leopard cats, negatively associated with oil palm plantations. Furthermore, we found preliminary evidence suggesting marbled cats may adapt their diel activity to become more crepuscular in degraded forests, likely shifting their activity to avoid humans. These findings suggest that the marbled cat's International Union for Conservation of Nature (IUCN) Red List conservation status should potentially be upgraded from Near Threatened to Vulnerable, matching other forest‐dependent felids in the region. We posit our findings may be generalizable such that semi‐arboreal and diurnal felids could face greater threats from habitat degradation than their terrestrial and nocturnal relatives.
Plant community assembly of alpine meadow at different altitudes in Northeast Qinghai‐Tibet Plateau

AbstractThe mechanism of community assembly is the core of ecological research. Using phylogenetic‐based and functional trait‐based methods jointly to explore the processes is a useful way to explain the change in assembly mechanisms. The present study combined these methods to explore the mechanism of plant community assembly in alpine meadows at different altitudes on the northeast Qinghai‐Tibet Plateau. We established a permanent study plot of 1.85 × 105 m2 and investigated 162 quadrats of 50 × 50 cm. We calculated the species richness, phylogenetic diversity (PD), standardized effect sizes PD (SES·PD), mean pairwise distance (SES·MPD), mean nearest taxon distance (SES·MNTD), and analyzed plant functional traits and phylogenetic signals. We found that the species richness and PD of plant community showed a “hump‐shaped” pattern, SES·PD showed a decreasing trend, and the phylogenetic structure changed from overdispersion (SES·MPD > 0, SES·MNTD > 0) to clustering (SES·MPD < 0, SES·MNTD < 0) with increasing altitude. The functional structure changed from overdispersion (nearest function index [NFI] < 0) to clustering (NFI > 0) with increasing altitude. Specific leaf area, leaf carbon content, and leaf phosphorus content had weak phylogenetic signals (K < 1, p < 0.05), and the other functional traits (plant height, leaf nitrogen content, leaf dry matter content, and relative chlorophyll content) did not show phylogenetic signals (K < 1, p > 0.05). The above results showed that competitive exclusion was the main driving force of community assembly at low altitudes (3000 and 3250 m), and habitat filtration was the main driving force of community assembly at high altitudes (4000 and 4500 m). For medium altitudes (3500 and 3750 m), the habitat was more complex because it was in the transition area between high and low altitudes, so the process of community construction may be random, habitat filtering, or competitive exclusion. On the whole, the niche process (deterministic process) was more important in driving for plant community assembly in the alpine meadow of the Qinghai‐Tibetan Plateau.

AbstractAlthough remote sensing of lake surface water temperature has been ongoing for decades and has led to important discoveries regarding the warming of lake surface temperature in some regions, the ability to access and use remote sensing data is still primarily limited to remote sensing experts. Effective use of remote sensing data involves technical skills in coding (often in multiple programming languages), application of appropriate atmospheric corrections, and integrating spatially heterogeneous remote sensing data with in situ data obtained at specific geographic locations. To improve access to remote sensing data and broaden the understanding of changes in lake surface water temperature over the past four decades, we created lakeCoSTR (lake Collection 2 Surface Temperature Retrieval), a user‐friendly, cloud‐based script that gives ecologists lacking specialized training in remote sensing the ability to access the Landsat Collection 2 temperature estimates for lakes with a surface area of at least 0.4 ha. Additionally, if in situ data are provided, a paired dataset can be created within the tool. To demonstrate lakeCoSTR, we retrieved surface water temperature data for a lake with a long monitoring history, Lake Sunapee, NH, USA, and compared long‐term surface temperature trends between data obtained via lakeCoSTR and in situ measurements. When compared with Landsat Collection 1 temperature estimates derived from a single‐channel algorithm, the Landsat Collection 2 data from lakeCoSTR required no calibration to in situ data. This suggests that lakeCoSTR can be used to document temporal trends in lakes and to reprocess analyses that relied on Collection 1 data. From 1983 until 2020, remotely sensed surface water temperature estimates at Lake Sunapee increased by 0.07–0.09°C year−1 during July and August, a trend that agreed with long‐term in situ record. As climate change continues to impact freshwater systems, a better understanding of long‐term temperature data will be vital. Remotely sensed data, like those acquired using lakeCoSTR, may provide a window into temperature trends for lakes.
