AbstractMonitoring the curing process of polymer composite parts stands imperative for improving the quality and efficiency of manufacturing processes. This paper proposes a field sensing framework that fuses parameterized physics‐informed neural networks (PPINN) and sparse fiber Bragg grating sensors to provide real‐time estimates of temperatures and degree of cure field in composite parts. Moreover, a novel separation network is developed for constructing the PPINN predictor, which integrates the coupled partial differential equation of the thermochemical curing process, achieving data‐free training and real‐time performance. In the simulation experiment, temperature accuracy reached 99.7%, while in laboratory experiments, the accuracy reached 96.1%. Both simulation and experiment demonstrated the successful field sensing of the temperature and degree of cure field in a negligible time with noise resistance ability.Highlights
Proposed framework integrates PPINN and sparse FBG sensors for field sensing.
PPINN solves thermo‐chemical equations without simulation data required.
Simulation accuracy reaches 99.7%, and experimental accuracy reaches 96.1%.
The framework shows strong resistance to noise interference in experiments.

ABSTRACTThis study aimed to explore the mental health status of individuals seeking rhinoplasty before and 3 months after surgery. This study was conducted in 2022 at Velayat Hospital, involving patients aged 18–60 who were seeking rhinoplasty, selected using convenience sampling method. Exclusion criteria included prior nasal surgery and severe psychiatric disorders without clearance from a psychiatrist. The Symptom Check List‐90‐Revised questionnaire was employed to assess psychological disorders across 9 dimensions. Sixty patients were examined, consisting of 14 men and 46 women, with an average age of 31 years. A substantial 83.3% of participants sought rhinoplasty solely for cosmetic reasons, whereas 16.7% cited both cosmetic and breathing issues as motivations. Initially, 59 patients had scores indicating “good” mental health, with one showing “moderate” mental health. Three months after the surgery, all patients scored within “good” mental health. The findings revealed significant improvements in various dimensions of mental health, including depression, anxiety, and obsessive compulsive symptoms, with the exception of paranoid ideation. All three primary indicators of mental health demonstrated significant decrease post‐surgery. The study highlights the positive impact of rhinoplasty on the mental health of patients, particularly among women, individuals over 20, and non‐smokers. Notable improvements were observed across various mental health dimensions, with significant enhancements reported three months post‐surgery. However, the findings underscore the need for careful consideration of psychological conditions when selecting candidates for surgery. Limitations, including a small male sample and lack of a control group, suggest further research is necessary.
Wet chemical synthesis of nanohydroxyapatite within poly(sodium sulfonated butylene fumarate‐co‐acrylic acid) as bone scaffold: effects of sulfonate and carboxylic acid groups

Published: December 2024

AbstractThis study investigates the synthesis, nucleation and modification of biodegradable poly(sodium sulfonated butylene fumarate‐co‐acrylic acid)/hydroxyapatite nanocomposite scaffolds for bone tissue engineering, with a focus on the effects of incorporating hydrophilic sulfonate and carboxylic acid groups. Poly(butylene fumarate) was sulfonated at varying degrees and used to form nanocomposites through in situ nucleation of nanohydroxyapatite (nHA) in a simulated body fluid solution. Critical parameters such as water absorption, swelling behavior, mechanical properties, nanoparticle dispersion and biocompatibility were evaluated. Water uptake ratios ranged from 2.72 to 6.88 g g−1, while compressive modulus values increased up to 25.9 times compared with the corresponding homopolymers, demonstrating improved mechanical stability. Despite the formation of over 80% nanoparticles, well‐distributed nHA, with sizes averaging 39 ± 13 nm, was achieved through the incorporation of sulfonated groups, preventing nanoparticle agglomeration within the scaffold matrix. Additionally, the scaffolds supported human dermal fibroblast adhesion and proliferation, with cell viability remaining high throughout the culture period. These results suggest that the developed nanocomposite scaffolds offer enhanced biocompatibility, mechanical strength and osteogenic potential, making them promising candidates for bone tissue regeneration applications. © 2024 Society of Chemical Industry.
E‐cigarette, or Vaping, Product Use Associated Lung Injury: Epidemiology, Challenges, and Implications With COVID‐19
Authors: Soerianto Winny , Jaspers Ilona 
Published: December 2024

ABSTRACTBackgroundE‐cigarette, or vaping products produce an aerosol by heating nicotine, or cannabis including tetrahydrocannabinol (THC) and cannabidiol (CBD), mixed with other chemicals that help make the aerosol. They are increasingly popular among teenagers and young adults, with a 2023 survey reporting that 2.13 million middle and high school students in the United States used e‐cigarettes within the last 30 days. The use of e‐cigarette, or vaping products could lead to an acute pulmonary inflammatory syndrome called e‐cigarette, or vaping, product use‐associated lung injury (EVALI). We review the challenges in diagnosing and treating EVALI, especially during the COVID‐19 pandemic.MethodsWe conducted a literature search on June 10, 2024 using the PubMed database. We searched for articles, case reports and CDC reports investigating the pathogenesis, treatment, and challenges of diagnosing EVALI during the COVID‐19 pandemic.ResultsThe exact causes of EVALI are not completely understood, although it has been linked to the use of THC and vitamin E acetate. There are no specific biomarkers to diagnose EVALI and it is typically diagnosed through a process of eliminating other possible conditions. Eight studies detailed cases where pediatric patients were initially diagnosed with COVID‐19 or community‐acquired pneumonia, despite multiple negative COVID‐19 tests, and were later found to have EVALI.ConclusionsAfter alerting the public about the removal of vitamin E acetate from vape liquids in 2020, there has been a decline in cases of EVALI, although they are still detected. Therefore, it is necessary to continue looking for diagnostic markers of EVALI and further investigate the toxicity of vapes and e‐cigarettes to prevent the recurrence of another EVALI epidemic, especially among teenagers and young adults.

ABSTRACTHydrogen‐deuterium exchange mass spectrometry (HDX‐MS) approach has become a valuable analytical complement to traditional methods. HDX‐MS allows the identification of dynamic surfaces in proteins. We have shown that the introduction of various mutations into the amino acid sequence of whale apomyoglobin (apoMb) leads to a change in the number of exchangeable hydrogen atoms, which is associated with a change in its compactness in the native‐like condition. Thus, amino acid substitutions V10A, A15S, P120G, and M131A result in an increase in the number of exchangeable hydrogen atoms at the native‐like condition, while the mutant form A144S leads to a decrease in the number of exchangeable hydrogen atoms. This may be due to a decrease and increase in the compactness of apoMb structure compared to the wild‐type apoMb, respectively. The L9F and L9E mutations did not affect the compactness of the molecule compared to the wild type. We have demonstrated that V10A and M131A substitutions lead to the maximum and large increase correspondently in the average number of exchangeable hydrogen atoms for deuterium, since these substitutions lead to the loss of contacts between important parts of myoglobin structure: helices A, G, and H, which are structured at the early stage of folding.

AbstractBACKGROUNDWhile the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ecological principles differ in agroecosystems is less explored. In this study, we investigated the ovipositional preference and offspring performance of fall armyworm (FAW) across vegetative and reproductive stages of soybean.RESULTSWe examined trichomes, volatile organic compounds (VOCs) and assessed electroantennogram (EAG) measurements to understand how olfactory responses are affected by volatiles at different phenological stages during photoperiodism (photophase and scotophase). We found that gravid FAW preferred the vegetative compared to reproductive stage of soybean. Although VOC and EAG responses was not statistically different (P > 0.05) between photophase and scotophase, but vegetative stage exhibited significantly (P ≤ 0.05) higher emissions and responses than the reproductive stage during both photophase and scotophase. Additionally, reproductive stage had lower trichomes compared to the vegetative stage. Interestingly, no significant difference was observed in offspring performance between the vegetative and reproductive stages of soybean. This suggests that oviposition preference does not necessarily correlate with offspring performance, which was confirmed through offspring mass and mass gain studies. Olfactory and sensory cues from soybean at reproductive stage reduced oviposition by mother FAW.CONCLUSIONCollectively, we show that while mother knows best may not fit FAW‐Soybean interaction, muffled volatile emission in reproductive stages can have positive consequences for host success. The results from this study will enhance our understanding of FAW behavior across different phenological stages of host plants, that can be used to develop alternative and sustainable management strategies. © 2024 The Author(s).

Dealing with steep slopes when modeling stable boundary‐layer flow in Alpine terrain
Authors: Bouëdec E. Le , Chemel C. , Staquet C. 
Published: December 2024

AbstractSteep slopes in mountainous terrain are challenging for commonly used numerical weather prediction models using terrain‐following coordinates since they can generate numerical errors when evaluating horizontal gradients, and numerical instabilities. The model orography is therefore generally smoothed locally so as to remove slopes exceeding a defined threshold, typically in the range 30°–40°. However, this process can lead to undesired changes to orographic features at the scale of the mountain range. So as to preserve properties of the orography, e.g., mean terrain height across the domain, a global smoothing algorithm is developed. The algorithm is then applied to a domain centred on the Alpine Grenoble valley. Exploration of the parameters of the algorithm allows to minimize the changes in the orography in the domain, especially that of the two main valleys (of width 2 and 5 km and depth about 2000 m). Results of numerical model simulations are next analyzed to evaluate the effects of the slope threshold on local‐ and valley‐scale atmospheric dynamics for a cold‐air pool episode. Model results from simulations with slope thresholds of 28° and 42° are compared, the lower threshold allowing for a reduction (albeit small in practice) of the near‐surface vertical grid spacing. Remarkably, not only are the near‐surface boundary‐layer temperature and wind fields similar for both simulations (and in very good agreement with observations), but this similarity holds in the whole inversion layer throughout the episode. The reasons for this similarity are that, for this cold‐air pool episode, the valley atmospheric dynamics is confined within the inversion layer and the orography is essentially unchanged by the smoothing algorithm in that layer for the slope threshold of 28° and 42°.

AbstractOrganic cropping systems may potentially improve soil and environmental health relative to simplified conventional systems due to the use of extended crop rotations, perennial crops, and animal manure. However, few studies have evaluated the impacts of organic row crop systems on a suite of soil health indicators relative to conventional systems across time. Thus, our objective was to assess how cropping system (conventional corn [Zea mays L.]–soybean [Glycine max L.] vs. organic corn–soybean–oat [Avena sativa L.]/alfalfa [Medicago sativa L.]–alfalfa vs. organic perennial pasture) and duration of management affect surface soil health indicators (soil biological, chemical, and physical properties) after 1–9 years of management in a Central Iowa Mollisol. Overall, the organic rotation improved six of 14 soil health indicators compared with the conventional system and the organic pasture improved eight indicators. The improved indicators included soil biological indicators, labile C and N pools, and wet‐aggregate stability, but not organic C or total N concentrations. Organic systems had fewer effects on most soil chemical properties. The conventional system reduced soil C by 0.35 g kg−1 year−1 (r = −0.84, n = 9, p = 0.005), unlike the organic systems in which soil C levels were generally maintained. The changes in soil health indicators were attributed to use of perennials, reductions in tillage frequency (during perennial phases), manure, and differing plant residue amounts among the three systems. In conclusion, organic cropping systems can enhance soil biological and related indicators in the medium term, but have fewer effects on soil fertility indicators under the conditions of this study.

AbstractThe integration of organic electronic materials with biological systems to monitor, interface with, and regulate physiological processes is a key area in the field of bioelectronics. Central to this advancement is the development of cell‐chip coupling, where materials engineering plays a critical role in enhancing biointerfacing capabilities. Conductive polymers have proven particularly useful in cell interfacing applications due to their favorable biophysical and chemical properties. However, n‐type conductive polymers remain underexplored, primarily due to their limited long‐term stability. In this study, it is demonstrated that the conductive polymer poly(benzimidazobenzophenanthroline) (BBL), commonly used in organic electronic devices, can effectively support neuronal cell viability and spreading, both as a bare cell culture material and when coated with exracellular matrix proteins. This work provides a preliminary validation of BBL's potential for future integration into bioelectronic devices and in biointerfacing.

AbstractAmong 2‐dimensional (2D) non‐layered transition‐metal chalcogenides (TMCs), cobalt sulfides are highly interesting because of their diverse structural phases and unique properties. The unique magnetic properties of TMCs have generated significant interest in their potential applications in future spintronic devices. In addition, their high conductivity, large specific surface area, and abundant active sites have attracted attention in the field of catalysis. However, the synthesis of phase‐controllable 2D non‐layered cobalt sulfide nanocrystals remains challenging. In the present study, a method is reported in which ambient‐pressure chemical vapor deposition (APCVD) is used to synthesize 2D non‐layered cobalt sulfide nanocrystals on insulating substrates. By controlling the growth temperature, the transition of nanocrystal phases from pyrite‐structured CoS2 to cubic Co3S4 and hexagonal CoS is achieved. Magnetotransport studies revealed metallic and ferromagnetic behaviors at temperatures below the Curie temperature for CoS2. In addition, electrical measurements of Co3S4‐ and CoS‐based devices showed conventional metallic behaviors, including temperature‐ and magnetic field‐dependent ordinary Hall effects. These findings demonstrate the potential of APCVD for synthesizing high‐quality 2D non‐layered cobalt sulfide nanocrystals with controllable phases, paving the way for their application in spintronics and catalysis.

AbstractTumor hypoxia and heat resistance as well as the light penetration deficiency severely compromise the phototherapeutic efficacy, developing phototherapeutic agents to overcome these issues has been sought‐after goal. Herein, a diradical‐featured organic small‐molecule semiconductor, namely TTD‐CN, has been designed to show low exciton binding energy of 42 meV by unique dimeric π‐π aggregation, promoting near‐infrared (NIR) absorption beyond 808 nm and effective photo‐induced charge separation. More interestingly, its redox potentials are tactfully manipulated for water splitting to produce O2 and reduction of O2 to generate O2•−. Besides, both ultrafast internal conversion and high‐frequency stretching vibrational relaxation of C≡N bonds favor photothermy. Accordingly, TTD‐CN nanoparticles have been prepared to exhibit spatiotemporally‐synchronous O2 and O2•− generation and 63.2% photothermal conversion under 808 nm laser irradiation for high‐efficient photodynamic and photothermal synergistic therapy. These findings successfully realize NIR light‐triggered spatiotemporally‐synchronous O2 self‐supply, type‐I photosensitization and superior photothermy in an organic small‐molecule phototherapeutic agent, significantly boosting the development of phototherapy.

Published: December 2024

AbstractCurrently, circularly polarized luminescence (CPL) has drawn wide interest in 3D display, information storage, and optical sensing. However, traditional synthetic paths are often accompanied by low chiral optical intensity and complex processes. Cellulose nanocrystals (CNCs), with the properties of liquid crystals, can spontaneously arrange into the left‐handed layered nanofilm, which enables them candidates in the construction of CPL materials. Following this approach, this work reviews the synthesis of cellulose‐based chiral luminescent materials. The co‐assembly technique, in situ intercalation strategy, and defect destruction design are efficient in encapsulating the luminophores into the CNC organization. Next, various strategies on the CPL regulation, including the matching of the photonic bandgap, optical pathway design, and tailored helical structure, are summarized. These offer new sights in the CPL control, mainly focusing on the amplification and inversion of optical signals. Multimodal and convertible chiroptical signals enable the photonic films with practical values in anti‐counterfeit, sensing, and handedness induction. Overall, this timely overview summarizes the synthesis, regulation, and application of cellulose‐based CPL materials, and aims to inspire the development of the chiral optical materials.

AbstractAnticipating intramolecular excited‐state proton‐coupled electron transfer (PCET) process within dinuclear Ir2‐photocatalytic system via the covalent linkage is seminal, yet challenging. Indeed, the development of various dinuclear complexes is also promising for studying integral photophysics and facilitating applications in catalysis or biology. Herein, this study reports dinuclear [Ir2(bis{imidazo‐phenanthrolin‐2‐yl}‐hydroquinone)(ppy)4]2+ (12+) complex by leveraging both ligand‐centered redox property and intramolecular H‐bonding for exploring dual excited‐state proton‐transfer assisted PCET process. The vital role of covalently placed hydroquinone in bridged ligand is investigated as electron–proton transfer (ET‐PT) mediator in intramolecular PCET and validated from triplet spin density plot. Moreover, bimolecular photoinduced ET reaction is studied in acetonitrile/water medium, forging the lowest energy triplet charge separated (3CSPhen‐Im) state of 12+ with methyl viologen via favorably concerted‐PCET pathway. The result indicates strong donor–acceptors coupling, which limits charge recombination and enhances catalytic efficiency. To showcase the potential application, this bioinspired PCET‐based photocatalytic platform is studied for phototherapeutics, indicating significant mitochondrial localization and leading to programmed cell death (apoptosis) through futile redox cycling. Indeed, the consequences of effective internalization (via energy‐dependent endocytosis), better safety profile, and higher photoinduced antiproliferative activity of 12+ compared to Cisplatin, as explored in 3D tumor spheroids, this study anticipates it to be a potential lead compound.
