Published: September 2023

Background

The prevalence of sleep deprivation among college students is increasing and has a few associated factors.

Methods

The present study analyzed 2,142 college students from 28 provinces in China. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep duration. Binary logistic regression was conducted to explore the sleep deprivation related factors. Age and gender were controlled as covariates.

Results

Among the 2,142 college students (27.7% male, 72.3% female), 1,620 (75.6%) reported the average sleep duration was below 7 h per day for one month, 49.3% (1,055/2,142) slept 6∼7 h (contains 6 h), 21.0% (449/2,142) slept 5∼6 h (contains 5 h), and 5.4% (116/2,142) slept <5 h. Age increased the risk of sleep deprivation, the adjusted odds ratio = 1.05 (95% CI [1.01∼1.10]). The adjusted odds ratio (A-OR) for sleep deprivation was higher for students of more than 60 min nap duration per day (A-OR = 2.35, 95% CI [1.45∼3.80]), and age growth (A-OR = 1.05, 95% CI [1.01∼1.10]). In contrast, A-ORs were lower among sleeping inconsistency between work and rest days (A-OR = 0.61, 95% CI [0.49∼0.75]), accustomed to staying up late (A-OR = 0.45, 95% CI [0.36∼0.57]), staying up late to work or study (A-OR = 0.62, 95% CI [0.49∼0.78]), stress (A-OR = 0.75, 95% CI [0.58∼0.98]), and repeated thoughts in bed had (A-OR = 0.79, 95% CI [0.62∼0.99]).

Conclusions

Sleep deprivation is extremely common among healthy college students in China. It is necessary to perform methods maintaining enough sleep due to the current high incidence of sleep deprivation. Controlling the nap duration and getting enough sleep on rest days to replace missing hours of sleep on workdays might improve college students’ sleep.

The myrtle (Myrtus communis) plant naturally grows in the temperate Mediterranean and subtropical regions and is used for various purposes; thus, it is among the promising species of horticultural crops. This study aimed to evaluate and compare the performance of different propagation systems, including rooting, solid media propagation, rooting, and with the Plantform bioreactor system, in achieving healthy and rapid growth of four myrtle genotypes with diverse genetic origins and well-regional adaptation. The selection of myrtle genotypes with distinct genetic backgrounds and proven adaptability to specific regions allowed for a comprehensive assessment of the propagation systems under investigation. Present findings proved that the Plantform system, the new-generation tissue culture system, was quite successful in micropropagation and rooting myrtle genotypes. We succeeded in vitro micropropagation and rooting of diverse wild myrtle genotypes, enabling year-round propagation without reliance on specific seasons or environmental conditions. The process involved initiating cultures from explants and multiplying them through shoot proliferation in a controlled environment. This contributes to sustainable plant propagation, preserving and utilizing genetic resources for conservation and agriculture.

Published: September 2023

Background

Since few studies have incorporated factors like stressors, coping styles, and academic burnout into the same model to analyze their impacts on depressive symptoms, this research attempts to establish an optimal structural model to explore the direct and indirect effects of these factors on depressive symptoms.

Methods

A total of 266 postgraduates completed questionnaires regarding coping styles, academic burnout, stressors, and depressive symptoms. The path analysis was applied for investigating the roles of coping styles and academic burnout in mediating the relationship between stressors and depressive symptoms.

Results

The total and direct effects of stressors on depressive symptoms were 0.53 and 0.31, respectively. The proportion of the direct effect of stressors on depressive symptoms to its total effect amounted to 58.50%. The indirect effects of academic burnout, positive coping style, and negative coping style on the association between stressors and depressive symptoms were 0.11, 0.04, and 0.03, taking up 20.75%, 7.55%, and 5.66% of the total effect, respectively. The serial indirect effect of positive coping style and academic burnout was 0.02, accounting for 3.77% of the total effect, while that of negative coping style and academic burnout was 0.02, taking up 3.77% of the total effect.

Conclusions

Coping styles and academic burnout chain jointly mediate the relationship between stressors and depressive symptoms among postgraduates. Thus, encouraging postgraduates to tackle stress positively may reduce the likelihood of the development of academic burnout and further reduce depressive symptoms.
Assessment of forces during side-posture adjustment with the use of a table-embedded force plate: Reference values for education
Authors: Russell Brent S. , Owens Edward F. , Hosek Ronald S. , Dever Lydia L. , Weiner Michael T.
Published: September 2023

Objective

Force-sensing treatment tables are becoming more commonly used by chiropractic educational institutions. However, when a table-embedded force platform is the sole measurement method, there is little information available about what force-time values instructors and students should expect for side-posture spinal manipulative thrusts. The purpose of this report is to provide force-time values recorded with such a system during side-posture manipulation with human recipients.

Methods

Student volunteers were examined by and received lumbar or pelvic side-posture manipulation from experienced chiropractors who were diplomates of the Gonstead Clinical Studies Society. Forces were recorded using proprietary software of a Bertec force platform; force and time data were analyzed with a custom-programmed software tool in Excel.

Results

Seven doctors of chiropractic performed 24 thrusts on 23 student recipients. Preload forces, averaging 69.7 N, and thrust loading duration, averaging 167 milliseconds, were similar to previous studies of side-posture manipulation. Peak loads were higher than previous studies, averaging 1010.9 N. Other variables included prethrust liftoff force, times from thrust onset to peak force and peak load to resolution of thrust, and average rates of force loading and unloading.

Conclusion

The values we found will be used for reference at our institution and may be useful to instructors at other chiropractic educational institutions, in the teaching of lumbar side-posture manipulation. A caveat is that the values of this study reflect multiple sources of applied force, not solely the force applied directly to the spine.

Authors: Nordbo Kajsa , Dewhurst Philip
Published: September 2023

Objective

To investigate if chiropractic placement students in the United Kingdom are aware of current pain evidence and how they relate this to the management of chronic pain patients. Moreover, to gain an understanding of how this can lead to improved pain education planning and engagement in the future.

Methods

The revised Neurophysiology of Pain Questionnaire and the researchers' own questionnaire were administered online to chiropractic placement students. The aggregated total number of correct responses and the individual mean scores were calculated. Statistical analysis included tests of normality and difference using the Kolmogorov-Smirnov, Mann-Whitney U, Kruskal-Wallis, and Χ2 tests.

Results

There was an overall response rate of 21.6% (n = 50). The mean score achieved on the revised neurophysiology of pain questionnaire was 37.8%. A significant difference between individual mean scores on the revised Neurophysiology of Pain Questionnaire was observed between male and female participants. No differences in mean score were observed between age, number of chronic pain patients seen, and previous qualifications. For the study-specific questionnaire, statistically significant differences were found in mean score for previous qualifications, number of patients seen, and sex.

Conclusion

Chiropractic placement students in the United Kingdom appear to have a lower level of pain knowledge than other health care professionals and education institutions may wish to consider how to best address this within their curricula.

Published: September 2023

With the fast-growing urbanization and increased industrialization around cities in Nigeria, the quality of the air we breathe has become a paramount concern. There is a need for an accurate, real-time air quality monitoring system to monitor and evaluate the air quality we inhale. This article presents the development of a Smart Air Quality Monitoring System (SAQMS) utilizing wireless sensor technology. The SAQMS was designed to provide a comprehensive and intelligent solution for monitoring air quality index, including but not limited to particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon monoxide (CO), temperature and humidity. Leveraging wireless sensor nodes and advanced IOT, the system offers real-time data collection and analysis, enabling immediate response to environmental changes. Key features of the SAQMS include a network of wireless sensors (MQ 135 and DHT11) strategically deployed across targeted areas, data transmission through secure communication protocols, cloud-based data storage and processing, and a user-friendly interface for data visualization and interpretation. As we confront the challenges of air pollution and its impact on human well-being, the development of the SAQMS presents a significant step towards informed decision-making and a more sustainable future as the experiment shows our developed system can detect air quality in parts per million (ppm), with other environmental factors such as temperature and relative humidity.

Published: September 2023

The method based on the description of the probabilities of states using a non-stationary Poisson flow allows using elementary reasoning to find not only a stationary, but also a non-stationary distribution of the number of requirements in the system.

To find a stationary distribution of the number of requirements in queuing systems (QS), the method of introducing additional variables leading to a piecewise linear Markov process is used.

The fact of invariance is shown: the stationary probabilities of pi states in queuing systems (QS) M/G/n/0 depend only on the average service time of the requirement and do not depend on the type of distribution G(x).

Published: September 2023

Barley (Hordeum vulgare L.) is one of the earliest cultivated cereals and a foundational crop of ancient agriculture. After rice, maize, and wheat, barley is the fourth most widely cultivated cereal crop in the world. It is cultivated in numerous developed and developing nations, where it frequently faces severe drought stress. Every year, droughts afflict the entire planet, frequently with catastrophic effects on crop production. Many crop modification projects have primarily targeted on the enhancement of drought resistance. However, progress toward this objective has been modest due to complexity of the trait, variability and unpredictability of the drought conditions in the field, and diversified drought tolerance mechanisms employed by plants. Barley is regarded as the most drought-resistant grain crop. It serves as an uncomplicated genetic model for studying drought tolerance mechanisms along with the associated agronomic and physiological traits. Several morphological, physiological, biochemical, molecular and quality traits were identified from various barley varieties and used to improve performance under drought stress. The present report is a comprehensive review that intends to give morphological, physiological, biochemical and genomic insights into the modulation of drought stress responses in barley and provide a thorough picture of drought tolerance mechanism.

Published: September 2023

The existence of genetic variability within a population is a fundamental requirement for promoting the effectiveness of any breeding operation. The study was carried out at Dr. RPCAU's research farm located in Pusa Samastipur, Bihar, during the kharif season of 2019-20. The objective was to assess the genetic variability among 23 cowpea genotypes (22 genotypes from various locations in the country and 1 check genotype). The study employed a randomised block design, consisting of three replications and a total of fifteen characters were recorded during the study. The analysis of variance (ANOVA) revealed statistically significant mean sum of squares (MSS) values attributed to genotype for all recorded variables, suggesting the existence of a substantial amount of diversity across the cowpea genotypes utilised in the study. In general, the recorded values for the Phenotypic Coefficient of Variation were found to be higher than those for the Genotypic Coefficient of Variation. The study observed high heritability estimates and high genetic advance for various traits, including plant height, number of leaves per plant, stem thickness, leaf-to-stem ratio, dry matter percentage, leaf fresh weight per plant, dry weight of stem per plant, seed yield per plant, and dry matter yield per plant. These findings suggest that the influence of the environment on these phenotypes is minimal. One of the key conclusions drawn from the study is that the direct selection of these traits can be employed to enhance fodder characteristics in cowpea.

Published: September 2023

Present study was undertaken to estimate the magnitude of genotype × environment interaction (GEI) and to identify stability of improved and high-yielding varieties of Indian mustard (Brassica juncea L. Czerns & coss.). The 57 Indian mustard genotypes were evaluated in RBD along with three replications during Rabi crop seasons in three environments. Analysis of variance on 14 traits was carried out individually as well as pooled over environments. Yield stability was analysed employing Eberhart and Russell’s model [1] which revealed highly significant differences among genotypes and environments. Mean squares due to environment + genotype x environment interactions (E + G x E) indicated that genotypes interacted considerably with environmental conditions. Further, partitioning of E+G x E effects indicated that E (linear), G x E (linear) components were highly significant for grain yield. Genotypes RH-749, DRMR 1165-40 X RH-406, DRMR IJ-31 X RH-749 had high mean than general mean coupled with regression coefficient close to unity bi = 1 and S2di = 0 and are identified as most stable and desirable Indian mustard genotypes.

Published: September 2023

Rice husk, an abundant agricultural byproduct, has garnered attention as a potential source of natural silica, a material with a myriad of applications. Natural silica is particularly attractive due to its low cost of production and safe handling. In this study, sodium silicate derived from rice husk ash was employed to create mesoporous nanosilica (MNS) via the sol-gel process. The extraction process commenced with the utilization of rice husk as a precursor for silica, capitalizing on its silica-rich composition. Fourier-transform infrared (FTIR) analysis was performed to ascertain the presence of Si-O-Si bonds within the synthesized MNS. This critical step confirmed the successful formation of silica-based materials. Subsequently, X-ray diffraction (XRD) analysis was employed, revealing a significant peak at 22 degrees, a clear indicator of the presence of crystalline silica. Examining the morphology of the MNS, field-emission scanning electron microscopy (FESEM) results showcased a smooth surface and spherical morphology. Additionally, high-resolution transmission electron microscopy (HR-TEM) was employed, revealing the presence of nanoparticles smaller than 100 nanometers, which is indicative of the mesoporous nature of the synthesized nanosilica. Characterization techniques, including FTIR, XRD, FESEM, and HR-TEM, provided compelling evidence of successful nanosilica extraction. The findings underscore the potential of utilizing agricultural waste products for the sustainable production of valuable materials like nanosilica, which holds promise in various industrial applications. This research not only contributes to the valorization of agricultural residues but also aligns with the pursuit of eco-friendly and cost-effective materials for a wide range of applications.

Assessing genetic diversity is the key factor for enhanced crop breeding programme which aids in improving desirable characteristics in the cultivars. In the present study, 200 rice landraces were initially screened using PEG at -7 bar concentration for drought tolerance. From the 200 landraces, 12 lines with 50 % germination were chosen to assess molecular and genetic divergence. A total of 50 SSR markers were utilized across the identified 12 drought tolerant genotypes along with two susceptible and two tolerant checks to assess divergence among the genotypes. Among the 50 SSR markers, 49 exhibited polymorphisms with a PIC value ranged from 0.82 (RM447) to 0.30 (RM418) with an average of 0.63. The number of alleles varied from two (RM408, RM418, RM512) to eight (RM404) with an average of 4.4 allele per marker and a total of 216 alleles were observed. Based on unweighted pair group of arithmetic mean (UPGMA) method a dendrogram was constructed and the genotypes were grouped in four main clusters. Among the four, cluster I holding more number of genotypes than cluster IV with high dissimilarity coefficient of 0.88. Further D2 analysis for five drought traits at seedling stage revealed the similarity and diversity among the landraces by separating them in different clusters based on genetic distance. The highest inter cluster distance of 175.96 were noticed between cluster 2 and 3 with high divergence which aids in better selection of landraces. Both molecular and genetic diversity shows distinct divergence among the genotypes which exhibits broader genetic base with wider adaptability.

Millets are renowned for their climatic resilience and possess high nutritive value with wide genetic variations. In countries like India and Africa, millets are part of many people's regular diets with rich sources of protein, dietary fiber, polyphenols, minerals, vitamins, and other nutrients. The proteomic signatures of several millet species, including Fonio, Finger, Proso, Sorghum, and Foxtail millet, were examined in this study. We have performed orthologous analysis to discover both common and distinctive protein clusters among these species by using the OrthoFinder algorithm in conjunction with visualization tools. A total of 16,247 clusters were shared by all species, offering light on similar evolutionary or adaptation mechanisms. The strong representation of Gene Ontology (GO) categories related to osmotic stress, water deprivation, and temperature stresses in the research further highlighted the millets' powerful adaptative responses to various environmental difficulties. Intricate signaling mechanisms for wound, defense, and growth are also revealed by their efficient photosynthetic capacities. However, each species' distinctive clusters, particularly those in Finger millet, highlighted how it differed from other millets. The evolutionary links were further clarified by a phylogenetic tree built using the Maximum likelihood approach and the JTT+CAT evolutionary model, with Foxtail and Proso millets showing a closer kinship. The research sheds light on the complex genetic network of millets, evolutionary histories, and potential adaptive processes. The identification of 2,277 clusters, which are mainly shared by foxtail, proso, fonio, and sorghum millets and support the distinct evolutionary history of finger millet, was especially important. These millets' strong adaptive mechanisms, which are on display in clusters related to different response mechanisms, demonstrate their evolutionary skill and point to prospective directions for crop improvement and resilience techniques.

Published: September 2023

Twenty-one genotypes of chickpea were used in the experiment, which was carried out by using a Randomized Block Design with three replications at the Department of Genetics and Plant breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Naini Allahabad, U. P during the rabi season of 2021-22. The present investigation was carried out to morphologically characterization and classify chickpea genotypes on the basis of DUS descriptors suggested by PPV& FRA. The observations were recorded on five randomly selected plants from each replication for 12 different quantitative traits. Analysis of variance showed significant differences for all the 12 characters viz., Days to 50 % Flowering, Days to Maturity, pod initiation, Plant Height, Number of Primary Branches, Number of Secondary Branches, number of pods per plant, Number of effective pods per plant, Number of seeds per plant, Biological Yield, Harvest Index, economic Yield Per Plant, Seed Index. The results of the analysis of variance showed that the majority of the qualities were significantly variable. Among twenty-one genotypes, CG-297 recorded high seed yield per plant followed by CG-255, CG-288, CG-210 and CG-214. All these genotypes recorded high seed yield as compare to check PUSA-362. High Genotypic Coefficient of Variation and Phenotypic Coefficient of Variation was observed for seed yield, seed index, harvest index, number of pods per plant, number of effective pods per plant. High heritability coupled with high genetic advance as percent of mean was observed for seed yield, seed index, harvest index, biological yield, number of pods per plant and number of effective pods per plant. The correlation studies revealed that seed yield per plant was positively and significantly correlated with pod initiation, plant height, number of pods per plant, number of effective pods per plant, biological yield, harvest index. The path analysis indicated that harvest index was observed as maximum positive direct effect on seed yield per plant and thus, may be considered as useful traits for yield improvement of chickpea.

Lactobacillus contribute to the organoleptic quality of foods during the fermentation process in which they are involved. They also have the ability to inhibit the growth of undesirable germs by producing metabolites such as bacteriocins. The aim of this study was to isolate and identify the different Lactobacillus species from various fermentation processes and from the Doderlein flora. Lactobacillus were isolated from raw cow milk, curdled milk, cassava ferment (Magnan) and Doderlein flora on MRS agar. Strains were identified by mass spectrometry (MALDI-TOF). 213 Lactobacillus strains were isolated and identified from the different matrices. The main species isolated from raw cow's milk and curdled milk were Lactobacillus plantarum (31.58%), Lactobacillus casei (26.31%), Lactococcus lactis (21.05%), Lactobacillus delbrueckii spp bulgaricus (31%), Lactobacillus helveticus (30%) and Lactobacillus fermentum (25%) respectively. In the cassava ferment, Lactobacillus plantarum (37.5%), Lactobacillus rhamnosus (25%) and Lactobacillus reuteri (25%) were the most isolated species. The main species of Doderlein flora were Lactobacillus acidophilus (50%) and Lactobacillus plantarum (25%). This study showed a diversity of Lactobacillus present and involved in the different fermentation processes of foods and Doderlein flora (Commensal flora of the vagina). The qualitative and quantitative proportions of the different Lactobacillus species depend on the matrix. These Lactobacillus can potentially produce substances (bacteriocins) that inhibit the growth of pathogenic bacteria and multi-resistant bacteria.
Full Recovery without Complications by Early Intervention for Malignant Hyperthermia that Occurred during General Anaesthesia: A Case Series of Two Infants with Facial Anomaly
Authors: Lee Jae Eun , Choi Hyoun Ho , Won Young Ju , Lim Byung Gun
Published: September 2023

Introduction: Malignant hyperthermia (MH) is a rare and life-threatening condition characterized by muscle rigidity, hypermetabolism, and other symptoms triggered by certain anaesthetic agents. It is linked to abnormal calcium release in skeletal muscles, often associated with genetic susceptibility or musculoskeletal disorders like scoliosis. Early recognition of MH symptoms, including muscle rigidity, tachycardia, and acidosis, is crucial for prompt intervention. Here, we report two infants with successful recovery following early MH intervention during general anaesthesia.

Case Report 1: A 26-month-old male with cleft hard palate, prematurity history, and chromosomal anomaly underwent palatoplasty. Anesthesia was induced with thiopental, fentanyl, and rocuronium, followed by sevoflurane/remifentanil maintenance. During surgery, the heart rate increased suddenly with hypercapnia. Hyperthermia of 39.5°C, suggestive of MH, arose. Sevoflurane was discontinued, cooling measures were initiated, and dantrolene was administered 2 hours later. Temperature normalized, ventilation improved, and extubation succeeded. Creatine phosphokinase (CPK) level was briefly elevated to 1062 IU/L but returned to normal. Despite being suspected of having MH, the patient was discharged without any complications after one day of intensive care unit (ICU) care.

Case Report 2: A 5-month-old female with cleft lip underwent cleft lip repair surgery. She had underlying congenital heart diseases. During anaesthesia, sudden hypercapnia and hyperthermia indicated potential MH. Sevoflurane was discontinued, and ketamine, and fentanyl were used to maintain anaesthesia. Dantrolene was administered after 80 min, cooling the patient and stabilizing the hypercapnia. The surgery ended 110 min after the sudden hyperthermia. In the ICU, metabolic acidosis was managed with sodium bicarbonate. Postoperative muscle enzyme, such as CPK, levels slightly rose, then normalized. Stable recovery led to discharge after 8 days without complications.

Conclusion: In both cases, MH occurred in infants with facial anomalies and early interventions, such as dantrolene administration, for suspected MH was done. Early suspicion, supported by diagnostic tools like the MH Clinical Grading Scale, is vital.

Importance

Collaborative dementia care programs are effective in addressing the needs of patients with dementia and their caregivers. However, attempts to consider effects on health care spending have been limited, leaving a critical gap in the conversation around value-based dementia care.

Objective

To determine the effect of participation in collaborative dementia care on total Medicare reimbursement costs compared with usual care.

Design, Setting, and Participants

This was a prespecified secondary analysis of the Care Ecosystem trial, a 12-month, single-blind, parallel-group randomized clinical trial conducted from March 2015 to March 2018 at 2 academic medical centers in California and Nebraska. Participants were patients with dementia who were living in the community, aged 45 years or older, and had a primary caregiver and Medicare fee-for-service coverage for the duration of the trial.

Intervention

Telehealth dementia care program that entailed assignment to an unlicensed dementia care guide who provided caregiver support, standardized education, and connection to licensed dementia care specialists.

Main Outcomes and Measures

Primary outcome was the sum of all Medicare claim payments during study enrollment, excluding Part D (drugs).

Results

Of the 780 patients in the Care Ecosystem trial, 460 (59.0%) were eligible for and included in this analysis. Patients had a median (IQR) age of 78 (72-84) years, and 256 (55.7%) identified as female. Participation in collaborative dementia care reduced the total cost of care by $3290 from 1 to 6 months postenrollment (95% CI, −$6149 to −$431; P = .02) and by $3027 from 7 to 12 months postenrollment (95% CI, −$5899 to −$154; P = .04), corresponding overall to a mean monthly cost reduction of $526 across 12 months. An evaluation of baseline predictors of greater cost reduction identified trends for recent emergency department visit (−$5944; 95% CI, −$10 336 to −$1553; interaction P = .07) and caregiver depression (−$6556; 95% CI, −$11 059 to −$2052; interaction P = .05).

Conclusions and Relevance

In this secondary analysis of a randomized clinical trial among Medicare beneficiaries with dementia, the Care Ecosystem model was associated with lower total cost of care compared with usual care. Collaborative dementia care programs are a cost-effective, high-value model for dementia care.

Bimetallic composites exhibit great potential as anode materials in advanced energy storage systems owing to their inherent tunability, cost‐effectiveness, and simultaneous achievement of high specific capacity and low reaction potential. However, simple biphase mixing often fails to achieve satisfactory performance. Herein, an innovative stress self‐adaptive bimetallic stellar nanosphere (50–200 nm) wherein bismuth (Bi) is fabricated, as a core, is seamlessly encapsulated by a tin (Sn) sneath (Sn‐Bi@C). This well‐integrated stellar configuration with bimetallic nature embodies the synergy between Bi and Sn, offering fortified conductivity and heightened sodium ion diffusion kinetics. Moreover, through meticulous utilization of finite element analysis simulations, a homogeneous stress distribution within the Sn‐enveloped Bi, efficiently mitigating the structural strain raised from the insertion of Na+ ions, is uncovered. The corresponding electrode demonstrates remarkable cyclic stability, as it exhibits no capacity decay after 100 cycles at 0.1 A g−1. Furthermore, it achieves an impressive 86.9% capacity retention even after an extensive 2000 cycles. When employed in a Na3V2(PO4)3 ‖ Sn‐Bi@C full cell configuration, it demonstrates exceptional capacity retention of 97.06% after 300 cycles at 1 A g−1, along with a high energy density of 251.2 W h kg−1.

Microporous annealed particle (MAP) scaffolds are injectable granular materials comprised of micron sized hydrogel particles (microgels). The diameter of these microgels directly determines the size of the interconnected void space between particles where infiltrating or encapsulated cells reside. This tunable porosity allows the authors to use MAP scaffolds to study the impact of spatial confinement (SC) on both cellular behaviors and the host response to biomaterials. Despite previous studies showing that pore size and SC influence cellular phenotypes, including mitigating macrophage inflammatory response, there is still a gap in knowledge regarding how SC within a biomaterial modulates immune cell recruitment in vivo in wounds and implants. Thus, the immune cell profile within confined and unconfined biomaterials is studied using small (40 µm), medium (70 µm), and large (130 µm) diameter spherical microgels, respectively. This work uncovered that MAP scaffolds impart regenerative wound healing with an IgG1‐biased Th2 response. MAP scaffolds made with large microgels promote a balanced pro‐regenerative macrophage response, resulting in enhanced wound healing with mature collagen regeneration and reduced inflammation levels.

Titanium selenide (TiSe2), a model transition metal chalcogenide material, typically relies on topotactic ion intercalation/deintercalation to achieve stable ion storage with minimal disruption of the transport pathways but has restricted capacity (<130 mAh g−1). Developing novel energy storage mechanisms beyond conventional intercalation to break capacity limits in TiSe2 cathodes is essential yet challenging. Herein, the ion storage properties of TiSe2 are revisited and an unusual thermodynamically stable twin topotactic/nontopotactic Cu2+ accommodation mechanism for aqueous batteries is unraveled. In situ synchrotron X‐ray diffraction and ex situ microscopy jointly demonstrated that topotactic intercalation sustained the ion transport framework, nontopotactic conversion involved localized multielectron reactions, and these two parallel reactions are miraculously intertwined in nanoscale space. Comprehensive experimental and theoretical results suggested that the twin‐reaction mechanism significantly improved the electron transfer ability, and the reserved intercalated TiSe2 structure anchored the reduced titanium monomers with high affinity and promoted efficient charge transfer to synergistically enhance the capacity and reversibility. Consequently, TiSe2 nanoflake cathodes delivered a never‐before‐achieved capacity of 275.9 mAh g−1 at 0.1 A g−1, 93.5% capacity retention over 1000 cycles, and endow hybrid batteries (TiSe2‐Cu||Zn) with a stable energy supply of 181.34 Wh kg−1 at 2339.81 W kg−1, offering a promising model for aqueous ion storage.
Crystal Engineering of Silica Anode Achieving Intrinsic Zero‐Strain
Authors: Wang Fei , Mao Jian , Zhao Yan
Published: September 2023

Si‐based anodes have large intrinsic volume expansion, which hinders their practicality and commercialization. To address this challenge, the design principle of intrinsic zero‐strain anodes (① large intracrystalline cavities and ② strong bonds) is proposed, and silica with large intracrystalline cavities (SLIC) established by strong Si─O bonds ([SiO4] coordinate structures) is obtained and acts as an anode, achieving the intrinsic zero‐strain feature first in silicon‐based anodes. The phase structure of SLIC is maintained and the [SiO4] coordinate structure merely shows slight disorder during cycling. The feature stems from lithiation taking place by the solid‐solution insertion reaction rather than the conventional conversion/alloying addition reactions, because the solid‐solution insertion reaction for the SLIC has the lowest change in the Gibbs free energy. The SLIC anode demonstrates excellent cycling stability and high initial Coulombic efficiency (≈85%). Moreover, owing to the low working voltage (≈0.28 V) and relatively high specific capacity, the SLIC anode presents the highest gravimetric energy density among reported zero‐/quasi‐zero‐strain anodes and high volumetric energy density (around twice as much as graphite). The universality of the designing principle is also validated. This work provides design guidelines for zero‐strain anodes in next‐generation batteries.
