Authors: Kumar Vineet , Alam Md. Najib , Park Sang‐Shin 
Published: June 2024

AbstractWearable technology refers to the devices that are integrated with textiles, or implanted in the body or plants for smart monitoring. Hence, this wearable technology has attracted tremendous attention from researchers globally due to its smart functions to be useful for mankind. The key target of this review is to examine the potential of rubber composite materials for such wearable devices. The rubber composites reviewed explore silicone rubber as a rubber matrix (SR). Another objective includes the use of multi‐walled carbon nanotubes (MWCNTs) in pristine and functionalization forms explored as reinforcing fillers. Moreover, prospects of CNT including their structure, properties, and types are explored both in pristine and functionalized state are reviewed. Following this, the mechanical, and electrical, properties of such composites are reviewed. The reported results show that the reinforcing properties are strongly improved by adding functional groups to CNT in rubber composite. These improvements in reinforcing properties are assisted by the functional groups like carboxyl (OH), carbonyl (CO), epoxy, and alkoxy (CO) on the surface of filler are useful. They assist in improving the filler‐rubber compatibility thereby improving filler dispersion and thus finally mechanical and electrical properties. Following this, such improved properties are explored for specific real‐time wearable technologies. This real‐time monitoring includes nursing plant pulse growth monitoring, health monitoring, and humidity sensors. The review further proposes that the functionalized CNTs can be useful for obtaining robust real‐time strain‐sensing monitoring. Moreover, it assists in obtaining sharp response time, strain sensitivity, and good stretchability. Finally, the prospects and challenges are explored discussing the real‐time monitoring of these sensors.Highlights
Configurations for nursing plant growth and other monitoring parameters are reviewed.
The properties of pristine and functionalized carbon nanotubes reinforced silicone rubber for wearable technology were reviewed.
The mechanical, and electrical aspects of functionalized carbon nanotubes were comparatively reviewed.
Applications such as wearable strain sensors, humidity sensors, and wearable plant pulse monitoring sensors were reported.
Parametric study on pyroelectric performances of functionally graded graphene nanoplatelet reinforced polyvinylidene fluoride composites
Authors: Zeng Bowen , Feng Chuang 
Published: June 2024

AbstractPolyvinylidene fluoride (PVDF) with pyroelectric properties has demonstrated great potential in sensors, actuators and structural health monitoring. However, the low content of β phase and the secondary pyroelectricity induced by thermal expansion limit its pyroelectric performances for a broader range of applications. In this work, graphene nanoplatelets (GNP) that have excellent physical properties are added to PVDF to improve the matrix's pyroelectric properties. To fully take advantage of the reinforcements, PVDF composite films with functionally graded (FG) distribution of GNP fillers are prepared. The pyroelectric properties of the FG films that are subjected to different scenarios are experimentally tested and analyzed. Combining experiments and finite element simulation, the secondary pyroelectricity of the multi‐layered FG films is particularly investigated for the first time. Compared to uniform dispersion, FG distribution of the GNP has an obvious effect on the pyroelectric performances of the PVDF composites. The increase in the number of layers and the thickness of the outer layers is beneficial for the improvement of the pyroelectric performances. The FG films with higher GNP concentration in the outer layer exhibit more favorable pyroelectricity. The parametric study is envisaged to provide guidelines for the design and optimization of the FG‐GNP/PVDF composites with improved pyroelectric performances.Highlights
FG‐GNP is favorable for pyroelectricity and stability of PVDF composite films.
GNP/PVDF composite films with more layers demonstrate superior pyroelectricity.
Attributes of layers have significant effects on pyroelectric responses.
Effects of factors associated with secondary pyroelectricity are quantitatively identified.

AbstractObjectiveTo explore the perspectives of pregnant women on broadening the scope of noninvasive prenatal testing (NIPT) from screening for foetal aneuploidies to prediction of adverse pregnancy outcomes.MethodsFour online focus groups (n = 23 participants) and 14 individual semi‐structured interviews were conducted. Participants included pregnant women with and without a history of adverse pregnancy outcomes.ResultsBoth women at low and high risk of adverse pregnancy outcomes had a positive attitude towards using NIPT to predict adverse pregnancy outcomes. Perceived benefits included the possibility to potentially improve maternal and foetal outcomes by taking risk‐reducing measures and/or intensified monitoring during pregnancy and the ability to mentally prepare for the potential adverse outcome. Perceived concerns included anxiety and stress caused by a high‐risk test result, a false sense of control over pregnancy, and potential false reassurance. Additionally, women reasoned that broadening the scope of NIPT could increase the complexity of prenatal screening and raised concerns on the combined screening aims in one test (prediction of adverse pregnancy outcomes to improve foetal and maternal health vs. screening for foetal aneuploidies to increase reproductive autonomy). On a societal level, considerations on the risk of medicalising pregnancy and overall pressure to opt for NIPT were mentioned.ConclusionIn general, pregnant women have a positive attitude towards broadening the scope of NIPT to the prediction of pregnancy outcomes, although some concerns are acknowledged.

Published: June 2024

AbstractForward osmosis (FO) has emerged as a highly promising and energy‐efficient technology for seawater desalination. This study investigates the enhancement of polyethersulfone/polysulfone FO membranes by incorporating graphene oxide (GO) for seawater desalination. The effects of different GO concentrations on membrane properties and FO desalination performance were examined. Among the tested membranes, the one with 0.04 wt% GO exhibited optimal hydrophilicity, as indicated by a lower contact angle (53.93° ± 5.61°), higher porosity (69.86 ± 0.66), and a minimal structure parameter (312.33 μm). The GO.04 membrane demonstrated significantly improved water flux (Jw) of 106 L/m2 h and low reverse salt flux (Js) of 0.69 g/m2 h. Compared to the GO0 membrane without GO, the water flux was 103% higher without compromising salt selectivity (Js/Jw = 0.0065 g/L) when using distilled water as the feed solution (FS) and 1 M NaCl as the draw solution. However, over a threshold of 0.09%, GO concentration on membrane surfaces and pores can impede water flow, reducing porosity and increasing resistance to membrane transport. The GO.04 membranes also exhibited high water flux (113, 94.28, and 84.64 L/m2 h) when brackish water with different NaCl concentrations (5000, 10,000, and 15,000 mg/L) was used as the FS. Moreover, under real seawater conditions from the Suez Canal, the GO.04 FO membrane showed a significantly higher water flux of 94.3 L/m2 h. These findings provide valuable insights into the desalination of actual seawater from the Suez Canal, offering significant potential for the advancement of water treatment and resource management practices.

Published: June 2024

AbstractThis research article focused on the blending of poly(lactic acid)/poly(methyl methacrylate) (PLA/PMMA) polymer materials to overcome PLA's inherent weaknesses, such as low glass transition temperature, brittleness, and lack of melt strength. Consolidated feasible characteristic investigations, such as mechanical, thermal, and aging behavior, were carried out for PLA/PMMA blended polymer materials. Initially, the miscibility of PLA/PMMA blend filaments was prepared at various blend ratios (91/9, 82/18, and 73/27) and samples were printed by fused deposition modeling (FDM). Differential scanning calorimetry (DSC) and Fourier infrared spectroscopy (FTIR) analysis have been utilized to evaluate the glass transition temperature (Tg) and intermolecular interaction, respectively, on blended polymer materials. Experimental tensile, compression, and flexural strength testing were performed on neat polymers and blended polymer composites. Compared to neat PLA materials, blended composites had 13.24% and 19.07% higher flexural and compression strengths. Besides, the interfacial interaction of neat and blended polymers has been done using dynamic mechanical analysis (DMA). Furthermore, Tg, storage modulus, and aging behavior of blended polymer materials have significantly improved over neat PLA materials. Altogether, the development of PMMA/PLA blends as sustainable biomaterials for dental applications aligns with environmental concerns and the need for biocompatible materials in dentistry.Highlights
Blending of PLA and PMMA helps mitigate the inherent constraints of PLA.
Blended composites exhibited greater compressive and flexural strengths.
Better glass transition temperature and intermolecular interaction.
Excellent thermal stability and water aging imply viable dental biomaterials.

AbstractBACKGROUNDUnderstanding how parasitoids respond to temperature is crucial for improving biological control strategies under the context of global warming. This study examined the suitability of Myzus persicae and its parasitoid Aphidius gifuensis to varying temperature conditions, as well as the stage‐specific response of A. gifuensis to high temperatures.RESULTSHigh temperatures had a significant impact on the both M. persicae and A. gifuensis. When exposed to 36°C, M. persicae developed more slowly and produced smaller adults compared to control, regardless of the duration of exposure (2, 4 or 6 h); additionally, the survival rate of M. persicae nymphs sharply decreased under these conditions. Exposure to 36°C for 4 h negatively impacted the development of A. gifuensis. Female parasitoids exposed to 32°C developed into smaller adults, whereas males exposed to all three temperature levels were smaller compared to control group. Female parasitoids exposed to high temperatures, regardless of the specific heat level and duration, exhibited reduced longevity and decreased fecundity. None of the parasitoids exposed to 36°C for 6 h daily developed into adults. Heat treated during early developmental stages (2 and 4 days old) had a greater influence on parasitoid development, whereas heat treatment at 4 and 6 days old had a more significant impact on its fecundity.CONCLUSIONHigh temperatures not only directly affected the performance of A. gifuensis, but also exerted indirect effects by influencing the quality of the host aphids M. persicae. The deleterious effects of high temperature on larvae can persist into the adult stage, affecting the longevity and reproduction of adults. These findings are important for the utilization of A. gifuensis in the control of M. persicae in warming environments. © 2024 Society of Chemical Industry.
Blood‐borne viruses and neurological manifestations: An overview
Authors: Xu Yan , Yu Bo 
Published: June 2024

AbstractInfections caused by blood‐borne viruses, such as human immunodeficiency virus (HIV), human T‐lymphotropic virus (HTLV), hepatitis C virus (HCV), and hepatitis B virus (HBV), are systemic diseases that can lead to a wide range of pathological manifestations. Besides causing severe immune and hepatic disorders, these viral pathogens can also induce neurological dysfunctions via both direct and indirect mechanisms. Neurological dysfunctions are one of the most common manifestations caused by these viruses that can also serve as indicators of their infection, impacting the clinical presentation of the disease. The main neurological manifestations of these blood‐borne viral pathogens consist of several central and peripheral nervous system (CNS and PNS, respectively) dysfunctions. The most common neurological manifestations of HIV, HTLV, HCV, and HBV include HIV‐associated peripheral neuropathy (PN), HTLV‐1‐associated myelopathy/tropical spastic paraparesis (HAM/TSP), and HCV‐/HBV‐associated PN, respectively. Nonetheless, patients infected with these viruses may experience other neurological disorders, either associated with these conditions or manifesting in isolation, which can often go unnoticed or undiagnosed by physicians. The present review aims to provide an overview of the latest evidence on the relationship between blood‐borne viruses and neurological disorders to highlight neurological conditions that may be somewhat overlooked by mainstream literature and physicians.
Ultraviolet‐visible‐near‐infrared light‐responsive soft materials: Fabrication, photomechanical deformation and applications
Authors: Zhang Peng , Wang Guojie , Yu Haifeng 
Published: June 2024

AbstractIn recent years, the advances in light‐responsive soft materials with fascinating properties and functions have attracted tremendous attention, which are also enlightening when attempting to achieve the goals of complex deformations, motions, or attractive applications by precise regulation. Attractively, light is not only a clean and inexhaustible energy but also can be controlled remotely, quickly and accurately in a non‐contact way. Moreover, light‐responsive soft materials are capable of amplifying photo‐triggered molecular changes at the microscopic scale into macroscopic deformations, that is, directly converting the input light energy into the output mechanical work, therefore enabling potential applications in the field of actuators and functional devices. To date, some wonderful reviews have reported the progress in photo‐driven soft materials. However, the research progress in ultraviolet, visible (Vis) and near‐infrared (NIR) light‐driven soft materials containing azobenzene or other non‐azobenzene moieties has not been reported yet. In this review, we summarize recent progress in light‐responsive soft materials in terms of preparation methods, response wavelengths and potential applications. Firstly, the preparation methods of photoresponsive soft materials are introduced. Subsequently, photoinduced macroscopic deformations or motions are summarized, in which Vis and NIR light‐responsive behaviors are especially highlighted. Finally, the potential applications of photoresponsive soft materials are classified. To guide the future work for researchers, the existing problems and future development prospects of light‐responsive soft materials are proposed.
Digital soil mapping of soil burn severity
Authors: Wilson Stewart G. , Prentice Samuel 
Published: June 2024

AbstractFire alters soil hydrologic properties leading to increased risk of catastrophic debris flows and post‐fire flooding. As a result, US federal agencies map soil burn severity (SBS) via direct soil observation and adjustment of rasters of burned area reflectance. We developed a unique application of digital soil mapping (DSM) to map SBS in the Creek Fire which burned 154,000 ha in the Sierra Nevada. We utilized 169 ground‐based observations of SBS in combination with raster proxies of soil forming factors, pre‐fire fuel conditions, and fire effects to vegetation to build a digital soil mapping model of soil burn severity (DSMSBS) using a random forest algorithm and compared the DSMSBS map to the established SBS map. The DSMSBS model had a cross‐validation accuracy of 48%. The established technique had 46% agreement between field observations and pixels. However, since the established technique is manual, it could not be compared to the DSMSBS model via cross‐validation. We produced SBS class uncertainty maps, which showed high prediction probabilities around field observations, and low probabilities away from field observations. SBS prediction probabilities could aid post‐fire assessment teams with sample prioritization. We report 107 km2 more area classified as high and moderate SBS compared to the established technique. We conclude that blending soil forming factors based mapping and vegetation burn severity mapping can improve SBS mapping. This represents a shift in SBS mapping away from validating remotely sensed reflectance imagery and toward a quantitative soil landscape model, which incorporates both fire and soils information to directly predict SBS.
Soil phosphorus continues to re‐equilibrate over 60 years of forest development in the Calhoun Critical Zone Observatory in the southeastern US Piedmont

Published: June 2024

AbstractLand use changes and reforestation impact soil phosphorus (P) distribution over extended periods. This study examines P distribution in forest development from 1957 to 2017 at the Calhoun Critical Zone Observatory in South Carolina. Tracking changes in 0–60 cm mineral soil P fractions through six samplings in eight continuously uncut plots and eight plots cut in 2007 (replanted in 2009), we hypothesized an increase in soil organic P (Po) over time in uncut plots, at the expense of HCl‐extractable P (i.e., Ca‐P). This hypothesis is based on the expectation of a transfer of P from easily accessible forms, possibly from historic fertilization to organic reservoirs within the soil. Meanwhile, we expect to lose Po in cut plots due to disturbance and residue decomposition, and increase bioavailable Mehlich‐III extractable P (Mehlich‐III P), resin inorganic phosphorus (Pi), and HCO3 Pi. Results revealed a continued decrease in Mehlich‐III P in uncut (38.7–15.7 µg g−1) and cut plots (25.2–17.7 µg g−1) within the 0–7.5 cm range. NaOH‐Po in uncut plots remained stable, while in cut plots, it increased by ∼4 µg g−1 in the 0–7.5 cm soil layer. Slowly cycling Po (NaOH‐Po) increased during forest regrowth in the cut plots, aligning with rising soil organic carbon and decreasing soil pH. Soil P changes indicate minor declines in available fractions during the initial three decades, with the HCl extractable (Ca‐P) fraction experiencing the highest depletion. In the later three decades, P associated with NaOH extraction (i.e., iron [Fe] and aluminum [Al] bound P) declined, although estimated mineral soil P removals during this period were less than accumulated P in tree biomass and forest floor. The total soil P decline from 1990 to 2017 was 34 kg ha−1, suggesting a growing role of P recycling from debris decomposition in supplying soil P to plants.

Published: June 2024

Abstract

Importance
Atopic dermatitis (AD) is associated with psychosocial symptoms, resulting in significant mental health burden and reduced quality of life.

Objective
To understand mental health support received by patients from their primary eczema provider.

Design
We administered a cross-sectional survey (N = 954) to US caregivers and adult patients with AD.

Setting
The National Eczema Association (United States) conducted an online survey in October 2022 among self-selected patients and caregivers.

Outcome
Patients and caregivers of AD patients reported on mental health conversations and types of mental health support received by their/their child’s provider.

Results
Many patients did not discuss (41.9%) or were not asked (50.5%) about their mental health by their eczema provider, and 64% reported not receiving a mental health referral. Patients were more likely to receive mental health support if they were male (2.00 [1.08–3.69]), low or middle education level (4.89 [2.10–11.36], 2.71 [1.36–5.40]), or had purchased insurance policies (4.43 [1.79–10.98]). Providers were most likely to refer patients to counseling services (22.5%), followed by alternative mental health therapy (14.9%), cognitive behavioural therapy (13.3%) and peer/social support groups (12.2%).

Conclusion
Despite the strong association between AD and mental health conditions, there is a significant proportion of patients that report not receiving mental health support from their/their child’s primary eczema provider. Screening with validated measures may improve the identification of patients requiring additional support. Future research should evaluate the efficacy of mental health resources and barriers to accessing and referring patients for mental health care.
Amplified psychological reaction to civil unrest among Holocaust survivor descendants

Published: June 2024

AbstractThe evidence regarding the intergenerational effects of the Holocaust points to a heightened sensitivity to traumatic and stressful events, as well as to threats. These effects were found across at least three generations: the survivors themselves, their children, and their grandchildren. More specifically, this sensitivity is manifested in increased psychological reactions to adverse circumstances, especially when such situations trigger associations with the Holocaust. During 2023 Israel has experienced unprecedented civil unrest and protests following the government's plan to promote a judicial overhaul. Many expressed fears for Israeli democracy and the integrity of the social fabric in Israel. The current study examined how Holocaust descendants (i.e., children and grandchildren of Holocaust survivors) experienced this prolonged social unrest. A web‐based random sample of 706 Israeli Jews born after World War II completed questionnaires several months before the unrest began (Wave 1, 2022) and seven months into the unrest (Wave 2, 2023). Supporting most of our hypotheses, Holocaust descendants reported higher civil unrest salience (i.e., more preoccupation with the political and social upheaval) relative to comparison descendants (i.e., children and grandchildren of those not directly exposed to the Holocaust). Relative to comparison descendants, Holocaust descendants were also at a greater risk of reporting exacerbation in anxiety since the judicial overhaul was introduced, but not in depression or somatisation symptoms. Results remained significant after controlling Wave 1 distress level, background characteristics, level of engagement in civil unrest, and participants' viewpoint on the judicial overhaul. The findings further corroborate unique reactions to stress among Holocaust descendants, this time by highlighting increased preoccupation and increased exacerbation in anxiety during a period of prolonged political and social turmoil.
