AbstractThe search for hydrogen storage materials allowing the storage of hydrogen in its molecular or atomic form at room temperature to meet the multistage targets such as the US Department of Energy (DOE) ultimate gravimetric and volumetric capacities of 6.5 wt% and 50 kg m‐3 is of global importance. Here, it is reported that an amorphized defective fullerene (C60‐x) offers a promising solution to this challenge. C60‐x immobilized with single‐atom platinum has ≈14‐fold higher surface area accessible for CH bonds compared to a crystalline C60, and its micro/meso pores give a ≈20‐fold larger volume for fast hydrogen transport. Indeed, hydrogen storage via spillover on C60‐x through pressure swing at room temperature is experimentally demonstrated to enable high reversible gravimetric (6.8 wt%) and volumetric (64.9 kg m‐3) capacities, hitherto the highest reversible capacities close to DOE targets at room temperature. Also, the density functional theory calculations show that a key to efficient hydrogen storage is the preservation of a curved sp2‐type local carbon geometry for spillover, which holds H radicals loosely for fast hydrogen migration. Moreover, H‐atom diffusion on the intact region of C60‐x is faster than that on the defect region. Furthermore, excellent capacity retention is achieved over repeated hydrogen adsorption/desorption cycles.

AbstractCu2ZnSn(S,Se)4 (CZTSSe) is a promising light absorbing semiconductor for solar energy conversion in photovoltaic cells and photo‐electrochemical (PEC) water‐splitting devices, owing to its earth‐abundant constituents, adjustable band‐gap, and superior absorption coefficient. However, the severe charge carrier recombination and the sluggish charge separation efficiency are the main issues obstructing the enhancement of device performance. In this work, a planar‐type Mo/CZTSSe/CdS/TiO2/Pt photocathode is fabricated. High‐quality CZTSSe film with compact and uniform crystal grains can be obtained via a two‐step process involving solution processed spin coating and thermally processed selenization. When an appropriate film thickness is used, both bulk defects and surface/interface defects are passivated, significantly suppressing the defects‐assisted recombination. Moreover, the benign energy band alignment of CZTSSe/CdS heterojunction is favorable to enhance photo‐generated charge separation and transfer efficiency. A remarkable photocurrent density of 40.40 mA cm−2 (at 0 VRHE) can be achieved, approaching to its theoretical value of 42.85 mA cm−2, and representing the highest value reported to date for kesterites‐based photocathodes. A champion CZTSSe photocathode with half‐cell solar‐to‐hydrogen conversion efficiency of 6.47% suggests a bright future for efficient solar hydrogen production applications.

Published: March 2023

AbstractAchieving high forage production—quantity and quality—could be challenging, specifically in water‐limited areas. Intensifying cropping systems with cover crops can provide agronomic and ecosystem service benefits. However, the impacts of cover crops on forage production have not been well studied. This study evaluated the effects of cover crops (grasses + brassicas + legumes [GBL], grasses + brassicas [GB], grasses + legumes [GL], and no cover crop [NCC] control) on sorghum silage [Sorghum bicolor (L.) Moench] yield and nutritive value over 3 years in a semiarid irrigated condition. Cover crops produced 2.1–6.0 Mg ha−1 of annual average harvestable biomass with similar forage nutritive value among treatments. In 2018–2019, sorghum silage yield was 38%–43% greater with all cover crops than with NCC. However, in 2019–2020, only GB had a 23% greater sorghum silage yield than NCC. The neutral detergent fiber content in sorghum silage was 4.8%–5.1% greater with all cover crops, and crude protein was 3%–8% lower with GL and GBL compared to NCC. Therefore, total digestible nutrients, relative forage quality, and milk production potential of sorghum silage were 5%–8%, 11%–19%, and 8%–16% greater, respectively, with NCC than with cover crops. This study demonstrates that replacing fallow with winter cover crops in irrigated silage production systems could provide good quality forage from cover crops without a decrease in subsequent sorghum silage yield. Sorghum silage quality slightly decreased with cover cropping. Nevertheless, cover crop integrated systems could be an alternative for farmers facing declining water availability for irrigated crop production.

Published: March 2023

AbstractObjectiveDespite studies on offspring obesity and delayed parenthood, little attention has been paid to the central obesity of offspring. The purpose of this study was to test the hypothesis that maternal age at childbirth (MAC) was associated with central obesity in offspring among the adult population, and fasting insulin may play a role in this association as a mediating factor.MethodsA total of 423 adults (mean age 37.9 years, 37.1% female) were included. Information about maternal variables and other confounders was collected by face‐to‐face interview. Waist circumference and insulin were determined through physical measurements and biochemical examinations. Logistic regression model and restricted cubic spline model were used to analyze the relationship between MAC and central obesity of offspring. The mediating effect of fasting insulin levels on association between MAC and offspring waist circumference was also analyzed.ResultsThere was a nonlinear relationship between MAC and central obesity in offspring. Compared with subjects with MAC 27–32 years, those with MAC 21–26 years (OR = 1.814, 95% CI: 1.129–2.915) and MAC ≥33 years (OR = 3.337, 95% CI: 1.638–6.798) had higher odds to develop central obesity. Offspring fasting insulin was also higher in MAC 21–26 years and MAC ≥33 years compared with those with MAC 27–32 years. Taking the group MAC 27–32 years as reference, the mediating effect of fasting insulin levels on the waist circumference was 20.6% and 12.4% for MAC 21–26 years and ≥ 33 years, respectively.ConclusionMAC 27–32 years has the lowest odds of central obesity in offspring. Fasting insulin levels may have a partial mediating effect on the association between MAC and central obesity.

AbstractObjectivesThis study aimed to determine the association of household fuel use with hypertension, systolic blood pressure (SBP), and diastolic blood pressure (DBP) among adult women.MethodsA cross‐sectional survey through face‐to‐face interviews and blood pressure (BP) measurement were conducted among 2182 randomly selected women (1236 solid fuel users and 946 clean fuel users) in rural areas of Bangladesh.ResultsOverall, 21% of women were hypertensive. Mean SBP and DBP for the study population were 121.27 mmHg (SD ± 15.43) and 76.18 mmHg (SD ± 12.00), respectively. Hypertension was found significantly (p = .006) higher among solid fuel users (23%) compared to clean fuel users (18%). Women using solid fuels have a 35% higher chance (AOR: 1.35, CI: 1.10–1.80) of having hypertension and have more than twice the risk of developing elevated SBP (AOR: 2.01, CI: 1.55–2.95) relative to women using clean fuels for their daily cooking. The probability of hypertension (AOR: 1.39, CI: 1.17–1.60) and elevated SBP (AOR: 1.35, CI: 1.10–1.61) increased significantly for every hour of fuel use.ConclusionsUsing clean fuel, reducing the duration of daily cooking time, and improved cooking facilities may help minimizing hypertension and ultimately cardiovascular disease risk among women.

AbstractCutis verticis gyrata (CVG) is classified as primary or secondary according to the absence or presence of underlying soft tissue abnormalities. We report an infant with Turner syndrome (TS) who in addition presented with CVG on the scalp. The skin biopsy revealed a hamartoma‐like lesion. We reviewed the clinical and histopathological findings of the 13 reported cases of congenital CVG in patients with TS, including ours. In 11 of them, CVG was localized on the skin of the scalp, mainly on the parietal region, and in two, on the forehead. Clinically, CVG had a flesh‐colored aspect, with absent or sparse hair, and was not progressive. CVG was classified as primary in four patients who had skin biopsy and it was attributed to the intrauterine lymphedema of TS. However, histopathology in two of these patients identified dermal hamartoma as a secondary cause of CVG, and in three others, including ours, there were hamartomatous changes. Although further studies are required, previous findings support the proposal that some CVG may instead be dermal hamartomas. This report alerts clinicians to recognize CVG as a low‐frequency manifestation of TS, but also to consider the possible co‐occurrence of TS in all female infants with CVG.

Published: March 2023

AbstractIntroductionAccording to previous estimates, 40% of dementia cases globally may be attributed to 12 potentially modifiable risk factors.MethodsWe calculated national population attributable fractions (PAFs) for each risk factor and modeled the effects of proportional reductions in risk factor prevalence on dementia prevalence by calculating potential impact fractions (PIFs) for each factor.ResultsThe overall adjusted PAF for all risk factors was 35.2%. Physical inactivity, hearing loss, hypertension, and obesity accounted for 64% of the total prevention potential. The overall adjusted PIF was 4.1% at 10% risk factor prevalence reduction and 8.1% at 20% risk factor reduction.DiscussionEstimates of the potential for the prevention of dementia should be based on country‐specific data on risk factor prevalence, as estimates based on global risk factor prevalence have limited relevance from a national perspective. Physical inactivity, hearing loss, hypertension, and obesity could be primary targets for prevention of dementia in Denmark.Highlights
Overall adjusted PAF for potentially modifiable dementia risk factors was 35%.
Physical inactivity, hearing loss, hypertension, and obesity had the largest prevention potential.
Estimates of prevention potential should be based on national risk factor prevalence.

AbstractElectrochemical two‐electron oxygen reduction reaction (2 e− ORR) to produce hydrogen peroxide (H2O2) is a promising alternative to the energetically intensive anthraquinone process. However, there remain challenges in designing 2 e− ORR catalysts that meet the application criteria. Here, we successfully adopt a microwave‐assisted mechanochemical‐thermal approach to synthesize hexagonal phase SnO2 (h‐SnO2) nanoribbons with largely exposed edge structures. In 0.1 M Na2SO4 electrolyte, the h‐SnO2 catalysts achieve the excellent H2O2 selectivity of 99.99 %. Moreover, when employed as the catalyst in flow cell devices, they exhibit a high yield of 3885.26 mmol g−1 h−1. The enhanced catalytic performance is attributed to the special crystal structure and morphology, resulting in abundantly exposed edge active sites to convert O2 to H2O2, which is confirmed by density functional theory calculations.

Published: March 2023

AbstractOily wastewater has caused serious damage to the human health and ecological environment. It is urgent to develop novel materials for high performance oil/water separation. Porous melamine sponges (MS) are considered as an ideal matrix material for oil/water separation. Herein, molybdenum sulfide (MoS2) modified with tannic acid (TA) and octadecylamine (ODA) was attached to MS framework via a facile dip‐coating method. This novel and eco‐friendly MS@(MoS2@ODA) sponge displays superior superhydrophobicity (WCA = 156.2°) and oil/water separation ability (absorption capacity = 113–145 g g−1). MoS2@ODA not only enhances surface roughness of MS framework, but also raises its specific surface area, causing an increase in the oil adsorption capacity of MS. Moreover, the composite sponge exhibited excellent chemical and mechanical stability. It is envisioned that this work can demonstrate a facile synthesis strategy for producing environmental friendliness MS with stable superhydrophobicity for high‐efficient oil/water separation.
Effect of dynamic vulcanization on the performance of high content rubber modified asphalt

Published: March 2023

AbstractHigh content rubber modified asphalt (HCRA) is usually prepared with devulcanized rubber (DR) in asphalt with good workability. However, the high‐temperature properties of HCRA deteriorate simultaneously. In this study, dynamic vulcanization approach was adopted to improve the high‐temperature properties of HCRA without mitigating the workability and low‐temperature performance of modified binder blends. The dynamic vulcanization process and mechanism were investigated based on the gel content, related chemical reactions, morphology, rheological behavior, and tensile properties of HCRA. The occurrence of dynamic vulcanization was confirmed by the increase in gel content. Fourier transform infrared spectroscopy reflected that CC bonds in trans‐olefins participated in dynamic vulcanization, followed by the reaction of those in conjugated olefins. Optical microscopy tests showed that dynamic vulcanization also improved the compatibility between the DR and asphalt. It was found that dynamic vulcanization of HCRA is the gradual stabilization process to form local cross‐linked networks in asphalt. With the addition of sulfur, degradation, aging, and dynamic vulcanization took place simultaneously in HCRA. Dynamic vulcanization increased the high‐temperature properties, fracture toughness, as well as storage stability of HCRA. Furthermore, dynamic vulcanization restricted rubber degradation and improved the aging behavior of HCRA.

Published: March 2023

AbstractThe domestic dog (Canis lupus familiaris) species comprises hundreds of breeds, each differing in physical characteristics, behavior, strength, and running capability. Very little is known about the skeletal muscle composition and metabolism between the different breeds, which may explain disease susceptibility. Muscle samples from the triceps brachii (TB) and vastus lateralis (VL) were collected post mortem from 35 adult dogs, encompassing 16 breeds of varying ages and sex. Samples were analyzed for fiber type composition, fiber size, oxidative, and glycolytic metabolic capacity (citrate synthase [CS], 3‐hydroxyacetyl‐coA dehydrogenase [3HAD], creatine kinase [CK], and lactate dehydrogenase [LDH] enzyme activities). There was no significant difference between the TB and VL in any of the measurements. However, there were large intra species variation, with some variables confirming the physical attributes of a specific breed. Collectively, type IIA was the predominant fiber type followed by type I and type IIX. The cross‐sectional areas (CSA) of the fibers were all smaller when compared to humans and similar to other wild animals. There was no difference in the CSA between the fiber types and muscle groups. Metabolically, the muscle of the dog displayed high oxidative capacity with high activities for CS and 3HAD. Lower CK and higher LDH activities than humans indicate a lower and higher flux through the high energy phosphate and glycolytic pathways, respectively. The high variability found across the different breeds may be attributed to genetics, function or lifestyle which have largely been driven through human intervention. This data may provide a foundation for future research into the role of these parameters in disease susceptibility, such as insulin resistance and diabetes, across breeds.
Relating the visceral factor of pain to domain‐specific risk attitudes

Published: March 2023

AbstractVisceral factors are negative emotions and drive and feeling states that grab people's attention and motivate them to engage in certain behaviors. They can contribute to discrepancies between an individual's long‐term self‐interest and their actual behavior. One such discrepancy concerns risk‐taking in health contexts as well as in a variety of other domains such as financial or career‐related decisions. This study examines the relationship between somatic symptoms of pain and domain‐specific risk attitudes in participants of a large population‐based cohort study. Somatic symptoms refer to back pain; pain in arms, legs, or joints; and headache. We show that the association between pain and risk attitudes is especially robust for the financial and leisure/sports domain across different model specifications. Pain is negatively associated with willingness to take risks in both domains. When controlling for fatigue (another visceral factor), the relationship between pain and risk attitudes persists only in the financial context. However, associations between fatigue and risk attitudes emerge in the general, health, leisure/sports, and career domains. We discuss potential implications of our findings especially in light of financial decision‐making.
A review of the coracoclavicular joint: Description, etiology, and clinical significance
Authors: Williamson Matthew A. 
Published: March 2023

AbstractThe coracoclavicular joint (CCJ) is a synovial joint that forms between the conoid tubercle of the clavicle and the coracoid process of the scapula in approximately 2.5% of the population. The number of bilateral to unilateral cases is almost equal. The number of right‐sided and left‐sided cases is also almost equal. It is found in both males and females but most often in male adults. Very few cases have been identified in juveniles. Found in populations all over the world, the highest frequencies of CCJ are in Asia. The etiology is unknown but it is most likely caused by metaplastic change of the trapezoid and surrounding tissue due to compression and friction of the coracoacromial ligament between the clavicle and coracoid process. Typically asymptomatic, but if so, the most common complaint is anterior should pain exacerbated by extreme abduction. Successful treatment includes steroid injection and surgical excision.

AbstractThe relationship between chronic myelogenous leukemia (CML) and tuberous sclerosis (TS) is unusual and uncommon. Here, we report a 24‐year‐old woman diagnosed with TS and later identified with CML, as the second case reported with such coexistence, treated with Nilotinib. This article proposes a hypothesis to explain the association. Therefore, we propose Nilotinib for the treatment of patients with such coexisting diseases. Further studies are warranted to reveal the dynamics between these conditions.
