AbstractThe objective of present research is to evaluate the changes in the chemical, microbial, and biogenic amines in Persian fish sauce (Mahyaveh) during 40 days of fermentation. In the current survey, the parameters of salt percentage, pH, total nitrogen concentration, amino nitrogen concentration, Brix, color features, cadaverine, and histamine concentration were measured in the fish sauce. The amino nitrogen content, total protein, Brix, and salt were increased along with the progression of fermentation process. The microbial population of Mahyaveh sauce demonstrated that lactic acid bacteria (LAB), total bacterial count, and Enterobacteriaceae decreased during fermentation. The population of lactic acid bacteria and the total count of bacteria were around one logarithmic cycle lower in the presence of 10% salt than under low salt conditions. Histamine and cadaverine concentrations increased to 43.49 and 42.76 mg/kg during the fermentation period, respectively. As a result, the population density of histamine‐producing bacteria rose from 3.00 log CFU/mL at the beginning to 4.58 log CFU/mL at the end of process. The population density of cadaverine‐producing bacteria was 3.43 and 5.24 log CFU/mL on the 20th and 40th days of fermentation, respectively. Sensory evaluation results indicated that our sample of fish sauce had an overall acceptability score of 5.1 (good). On the other hand, Principal Component Analysis (PCA) demonstrated a positive correlation between the most of chemical parameters and the fermentation period. The concentration of cadaverine and histamine has a positive association with the pH and type of bacteria producing the biogenic amines.

AbstractAsparagus, a vital economic contributor, is a well‐liked vegetable grown around the globe, and some secondary metabolites in its spear are beneficial to human health. Asparagus spears possess a significant quantity of nutrients and phytochemicals; however, the difference in these chemical compositions among various varieties has not been sufficiently studied. This work aimed to detect the chemical compositions of 30 varieties of asparagus and to assess them by principal component analysis (PCA). The results showed that the contents of these chemical compositions varied in varieties. Selenium (Se, 1.12–2.9 μg/100 g dry‐weight [DW]) was abundant in asparagus, with an average dry matter content of 8.25%. Free amino acids (5.60–9.98 g/100 g DW) and polyphenols (6.34–8.67 mg/g DW) were both present in high amounts, along with flavonoids (4.218–8.22 mg/g DW) and protodioscin (0.44–1.96 mg/g DW). Correlation analysis, PCA, and hierarchical cluster analysis were used to conduct a comprehensive evaluation of asparagus. Atlas, Appolo, Jinggang 111, Jingke 2, and WS‐1 were the top five varieties with comprehensive scores. This study provided valuable data for the breeding, quality improvement, processing, and utilization of asparagus varieties in the future.

AbstractThermal enhancement remains a critical requirement in different engineering applications. Many factors can affect the efficiency of the techniques used for this aim. The purpose of this study is to investigate the impact of particle‐fluid suspensions with heat transfer through porous annular‐sector duct on enhancement techniques and address the potential application of deep learning to suspension problems. The analysis is focused on the fully developed region of the forced convection flow. Thermal and rheological properties of particle‐fluid suspensions were studied using physics‐informed neural networks exploiting transfer learning capabilities for making parameter analysis. Another finite element solution was introduced as a measure of accuracy and to support our findings. Results were prepared in a comparative manner for both solvers including contour plots, tabular, and two dimensional figures. The average Nusselt number and friction factors were calculated for different cases to investigate the value of the thermal performance factor. Our results indicate the downside of suspensions on thermal enhancement and their negative impact on other techniques.

AbstractThe release of extracellular vesicles (EVs) in cell cultures as well as their molecular cargo can be influenced by cell culture conditions such as the presence of foetal bovine serum (FBS). Although several studies have evaluated the effect of removing FBS‐derived EVs by ultracentrifugation (UC), less is known about the influence of FBS heat inactivation (HI) on the cell‐derived EVs. To assess this, three protocols based on different combinations of EV depletion by UC and HI were evaluated, including FBS ultracentrifuged but not heat inactivated (no‐HI FBS), FBS heat inactivated before EV depletion (HI‐before EV‐depl FBS), and FBS heat inactivated after EV depletion (HI‐after EV‐depl FBS). We isolated large (L‐EVs) and small EVs (S‐EVs) from FBS treated in the three different ways, and we found that the S‐EV pellet from HI‐after EV‐depl FBS was larger than the S‐EV pellet from no‐HI FBS and HI‐before EV‐depl FBS. Transmission electron microscopy, protein quantification, and particle number evaluation showed that HI‐after EV‐depl significantly increased the protein amount of S‐EVs but had no significant effect on L‐EVs. Consequently, the protein quantity of S‐EVs isolated from three cell lines cultured in media supplemented with HI‐after EV‐depl FBS was significantly increased. Quantitative mass spectrometry analysis of FBS‐derived S‐EVs showed that the EV protein content was different when FBS was HI after EV depletion compared to EVs isolated from no‐HI FBS and HI‐before EV‐depl FBS. Moreover, we show that several quantified proteins could be ascribed to human origin, thus demonstrating that FBS bovine proteins can mistakenly be attributed to human cell‐derived EVs. We conclude that HI of FBS performed after EV depletion results in changes in the proteome, with molecules that co‐isolate with EVs and can contaminate EVs when used in subsequent cell cultures. Our recommendation is, therefore, to always perform HI of FBS prior to EV depletion.
Effects of year‐long exposure to elevated pCO2 on the metabolism of back reef and fore reef communities

Published: January 2024

AbstractThe implications of ocean acidification are acute for calcifying organisms, notably tropical reef corals, for which accretion generally is depressed and dissolution enhanced at reduced seawater pH. We describe year‐long experiments in which back reef and fore reef (17‐m depth) communities from Moorea, French Polynesia, were incubated outdoors under pCO2 regimes reflecting endpoints of representative concentration pathways (RCPs) expected by the end the century. Incubations were completed in three to four flumes (5.0 × 0.3 m, 500 L) in which seawater was refreshed and circulated at 0.1 m s−1, and the response of the communities was evaluated monthly by measurements of net community calcification (NCC) and net community productivity (NCP). For both communities, NCC (but not NCP) was affected by treatments and time, with NCC declining with increasing pCO2, and for the fore reef, becoming negative (i.e., dissolution was occurring) at the highest pCO2 (1067–1433 μatm, RCP8.5). There was scant evidence of community adjustment to reduce the negative effects of ocean acidification, and inhibition of NCC intensified in the back reef as the abundance of massive Porites spp. declined. These results highlight the risks of dissolution under ocean acidification for coral reefs and suggest these effects will be most acute in fore reef habitats. Without signs of amelioration of the negative effects of ocean acidification during year‐long experiments, it is reasonable to expect that the future of coral reefs in acidic seas can be predicted from their current known susceptibility to ocean acidification.
Current insights into the factors affecting the erosion behaviour of iron alloy based coating material
Authors: Kumar S. R. , Sharma R. K. 
Published: January 2024

AbstractThe present paper reviewed the role of factors influencing the wear properties of iron alloy‐based coating material. In brief, these factors are categorized into four major types such as substrate properties, high‐velocity oxy‐fuel spraying parameters, heat treatment processes and wear testing parameters. Substrate properties include roughness, thermal resistance, and adhesive strength between substrate and coating materials. High velocity oxy fuel parameters include spray distance, oxygen flow rate, fuel flow rate, angle of spray, spray density, coating speed, thickness, number of coating layers etc. Erosion wear testing parameters include impact speed, impingement angle, erodent discharge, slurry concentration etc. Furthermore, erosion wear testing parameters are sub‐categorized into three types which are particulate‐based parameters such as size, shape and hardness of particle, impact‐based parameters such as angle of impact, impact velocity, and composition‐based parameters such as microstructure, physical and mechanical properties of materials. The annealing process speeds up the development of crystal phases. Therefore, to get the best coating materials, a detailed investigation and optimization of all the factors must be performed.
Simulation of wire metal transfer in the cold metal transfer (CMT) variant of gas metal arc welding using the smoothed particle hydrodynamics (SPH) approach

Published: January 2024

AbstractCold metal transfer (CMT) is a variant of gas metal arc welding (GMAW) in which the molten metal of the wire is transferred to the weld pool mainly in the short‐circuit phase. A special feature here is that the wire is retracted during this strongly controlled welding process. This allows precise and spatter‐free formation of the weld seams with lower energy input. To simulate this process, a model based on the particle‐based smoothed particle hydrodynamics (SPH) method is developed. This method provides a native solution for the mass and heat transfer. A simplified surrogate model was implemented as an arc heat source for welding simulation. This welding simulation model based on smoothed particle hydrodynamics method was augmented with surface effects, the Joule heating of the wire, and the effect of the electromagnetic forces. The model of metal transfer in the cold metal transfer process shows good qualitative agreement with real experiments.

Published: January 2024

AbstractPolyacetylenes with good performance in O2/N2 separation were reported. A series of cis‐helical poly(trialkylsilylethynylphenylacetylene)s (PSEPAs) with average molecular weight in the range of 105–106 g mol−1 are synthesized under the catalysis of [Rh(nbd)Cl]2. The free‐standing membranes are prepared from the solution of PSEPAs in chloroform. A rigid PSEPA membrane exhibits the tensile strength of 22.2 MPa, while a flexible PSEPA membrane shows an elongation at break of 44.2% at room temperature. Moreover, the rigid PSEPA membrane shows ultra‐high oxygen permeability of 3.09 × 105 Barrer. The results show that PSEPAs are potential polymers for the applications in O2/N2 separation field.

AbstractThe persistent organic pollutant chlordecone massively contaminates water resources of the French West Indies. Hemicryptophanes are cages capable of complexing chlordecone in organic solvents. Here we demonstrate that a hemicryptophane cage is not only able to recognize this pollutant in chloroform but is also efficient for the removal of chlordecone from water. This evidences that, beyond our previously reported proof of concept, this receptor could be apply as a direct and efficient depolluting agent, making it a promising system for applied supramolecular chemistry. A simple pH switch (basic washing) enables the release of chlordecone from the host, under its deprotonated form, allowing the empty supramolecular cage to be recycled and reused. This method for recycling the receptor, is to the best of our knowledge unprecedented.

Published: January 2024

AbstractG‐quadruplexes are secondary structures of nucleic acids increasingly employed for biological and also technological applications. Being of particular interest, a structural motif called quadruplex‐duplex (QD) hybrid comprises both a G‐quadruplex and duplex domain. Here, we attempted to engineer a bimolecular quadruplex‐duplex hybrid through dual recognition of a receptor by a target strand with the simultaneous formation of both G‐quadruplex and duplex structures. Three different constructs were designed for the G‐quadruplex receptor, featuring either one, two, or three vacant sites. Addition of the target strand filled the vacancies when simultaneously hybridizing with flanking sequences to form a duplex as shown by NMR studies. Formed QD hybrid constructs either constitute an 11 : 1, 10 : 2, or 9 : 3 split G‐quadruplex system. The 10 : 2 QD construct folds into a non‐canonical V‐loop topology. Remarkably, the latter also accommodates 5’‐overhang residues of the target strand although suggested to impose a steric penalty. Formation of the duplex domain is demonstrated to be critical for the successful formation of the intact G‐quadruplex domain. With the formation of a unique QD junction for detection, the constructs may constitute valuable tools for single strand capturing strategies.

AbstractHerein, the structure of integrated M3D inverters are successfully demonstrated where a chemical vapor deposition (CVD) synthesized monolayer WSe2 p‐type nanosheet FET is vertically integrated on top of CVD synthesized monolayer MoS2 n‐type film FET arrays (2.5 × 2.5 cm) by semiconductor industry techniques, such as transfer, e‐beam evaporation (EBV), and plasma etching processes. A low temperature (below 250 °C) is employed to protect the WSe2 and MoS2 channel materials from thermal decomposition during the whole fabrication process. The MoS2 NMOS and WSe2 PMOS device fabricated show an on/off current ratio exceeding 106 and the integrated M3D inverters indicate an average voltage gain of ≈9 at VDD = 2 V. In addition, the integrated M3D inverter demonstrates an ultra‐low power consumption of 0.112 nW at a VDD of 1 V. Statistical analysis of the fabricated inverters devices shows their high reliability, rendering them suitable for large‐area applications. The successful demonstration of M3D inverters based on large‐scale 2D monolayer TMDs indicate their high potential for advancing the application of 2D TMDs in future integrated circuits.
High‐Temperature Melt Stamping of Polymers Using Polymer/Nanoporous Gold Composite Stamps

Published: January 2024

AbstractParallel lithographic deposition of polymers onto counterpart substrates is a widely applied surface manufacturing operation. However, polymers may only be soluble in organic solvents or are insoluble at all. Solvent evaporation during stamping may trigger hardly controllable capillarity‐driven flow processes or phase separation, and polymer solutions may spread on the counterpart substrates. Solvent‐free stamping of melts prevents these drawbacks. Here, a stamp design for the deposition of melts is devised, which intrinsically circumvents ink depletion. The stamps’ topographically patterned contact surfaces with protruding contact elements contacting the counterpart substrates consist of a nanoporous gold layer with a thickness of a few micrometers. The nanoporous gold layer is attached to a molten polymer layer, which is support for the nanoporous gold layer and ink reservoir at the same time. The nanoporous gold layer in turn stabilizes the topography of the stamps’ contact surfaces. As examples, arrays of submicron microdots of polystyrene and poly(vinylidenefluoride‐trifluoroethylene) (PVDF‐TrFE) are manufactured. The P(VDF‐TrFE) microdots are partially crystalline, ferroelectric, and can be locally poled. It is envisioned that the methodology reported here can be automatized and may be extended to functional low‐molecular‐mass compounds, such as active pharmaceutical ingredients.

AbstractMost coal in India originates from the Korb basin (Chhattisgarh), where coal mines, thermal power, and aluminum plants operate. Groundwater in this region faces severe pollution due to land reclamation, leaching of coal‐related contaminants, waste disposal, and industrial effluent seepage. This work presents results from monitoring groundwater pollution in the Korba basin from 2012 to 2017. Fluoride, aluminum, manganese, and iron levels exceeded acceptable quality limits across all 28 studied locations, with excessive nitrate, magnesium, calcium, and lead levels in specific sites. Tracking seasonal and temporal fluctuations in the most polluted site, namely Kudurmal, revealed peak solute concentrations during the monsoon period and a sustained 18% increase during the study period. Factorial analysis suggests groundwater contamination arises from both human activities and natural sources. These findings underscore the urgent necessity of devising remediation strategies for the drinking water supply.
Building digital solutions to support brain health prescribing in primary care: Where to begin?

Published: January 2024

AbstractNational and international policy goals on healthy ageing and dementia risk reduction are yet to be fully realised in community healthcare settings. Disease modification strategies through lifestyle and social interventions are viable, evidence‐based solutions to reduce age‐related disease burden. However, prescribing lifestyle interventions targeting dementia risk in primary care remains deficient. Using digital technologies to support older individuals and healthcare professionals through formal health checks and lifestyle management is likely to enable shared understanding and consequences of personalized care and treatment options. These tailored solutions may bridge the translation gap and support healthy ageing.
New and Not‐Well‐Known Research about Reading Disabilities: Teachers Want to Know

Published: January 2024

AbstractLaws, practices, and research about reading difficulties have been gradually and rapidly changing since the passage of the Individuals with Disabilities Education Act in 1974. It is difficult for schools to keep up, especially when it takes approximately 16 years for research to reach widespread public knowledge. In this article, I frame the latest research about reading difficulties within the daily discussions occurring in schools. I address misconceptions and best practices about dyslexia, learning disabilities, screening, instruction, and a common, but unknown cause of reading difficulties—developmental language disorder. Research cited in this article come from studies funded by the National Institutes of Child Health and Development and the Institute of Education Sciences.
Combination effect of ADP‐intercalated kaolinite and ammonium polyphosphate on simultaneously enhancing the flame retardancy and smoke suppression of epoxy resins

Published: January 2024

AbstractIn this article, ammonium dihydrogen phosphate (ADP) was successfully intercalated into kaolinite (Kaol) to prepare a novel synergist named ADP‐intercalated kaolinite (K‐ADP). The chemical structure of K‐ADP was thoroughly characterized using various analytical methods, and then K‐ADP was combined with ammonium polyphosphate (APP) to enhance the fire safety of epoxy resins (EPs). The flammability results indicate that the combination of K‐ADP and APP exerts super positive effects on reducing the heat release and smoke emission of EPs than the mixture of Kaol and APP. Especially, the EP/8 wt% APP/2 wt% K‐ADP has a super LOI value of 33.2% and reaches a UL94 V‐0 rating accompanying with a 29.1% reduction in total heat release (THR) and a 72.7% reduction in total smoke production (TSP) compared to pure EP. The morphology and component analyses show that the combination of K‐ADP and APP facilitates the formation of more phosphorus‐rich crosslinking and aromatic structures in the condensed phase to enhance the compactness and intumescence of char layer, which effectively segregates heat, combustible compounds and smoke particles. Thermogravimetric analysis shows that the combination of K‐ADP and APP exerts super char‐forming ability in EPs, and the residual weight of EP/8 wt% APP/2 wt% K‐ADP at 800°C increases from 7.8% of pure EP to 19.7%. Mechanical test shows that the addition of K‐ADP displays the less adverse effect on the mechanical properties of EP composites compared to Kaol due to the better compatibility of K‐ADP and epoxy matrix with DSC analysis support.Highlights
A novel ammonium dihydrogen phosphate‐intercalated kaolinite (K‐ADP) was synthesized.
APP/K‐ADP system exerts super positive effect on reducing fire hazards of EPs.
APP/K‐ADP system takes effect in both gas phase and condensed phase.
