AbstractThis study presents a novel approach for dual detection, leveraging a combination of a Raman reporter‐bearing nanomaterial and molecular imprinting polymers (MIP). A core‐shell Au‐Ag nanoparticles (Au‐Ag NPs) encapsulated in mesoporous silica nanocapsules (Au‐Ag NCs) and a new MIP‐based material targeting L1CAM are used. The MIP prepared via surface imprinting on a carbon screen‐printed electrode (C‐SPE) used thionine (TH) as a monomer. The plasmonic Au‐AgNCs are further functionalized with the Raman reporter 4‐mercaptobenzoic acid (MBA) and anti‐L1CAM for selective detection by surface‐enhanced Raman scattering (SERS) spectroscopy. The biosensor's analytical performance is evaluated using both SERS and electrochemical impedance spectroscopy (EIS). EIS analysis reveals a linear response within the concentration range of 0.1 to 100 ng mL−1 in buffer and serum samples. SERS demonstrates a sensitivity ten times higher than EIS. Selectivity study demonstrates the biosensor's excellent specificity toward L1CAM, with minimal interference from other compounds such as creatinine, glucose, and carbohydrate antigen 19‐9 (CA 19‐9). The Raman signal from the reporter molecule correlates with increasing L1CAM concentrations, reinforcing the analytical findings obtained through electrochemical analysis. Thus, the combination of dual detection and recognition capabilities presents promising potential for detecting diverse biomarkers, especially in critical scenarios where reducing false‐positive or false‐negative errors is crucial.

Published: October 2024

AbstractAgrometeorological data are essential for understanding production using digital agriculture techniques. However, integrating agrometerological observations from multiple sources remains a challenge. Often, digital agriculture scientists download and clean the same datasets many times. We present a prototype system that simplifies the process of collecting, cleaning, integrating, and aggregating data from meteorological data sources by providing a simplified user interface, database, and application programming interface. The prototype provides a standard interface for querying multiple geospatial formats (raster and vector) and integrates observation networks including the National Oceanic and Atmospheric Administration Global Historical Climatology Network (NOAA GHCN), NOAA NClim‐Grid (NOAA's Gridded Climate Normals), and Ameriflux BASE. The system automatically checks and updates data, saving storage space and processing time, and allows users to summarize data spatially and temporally. Provided as open source code and browser‐based user interface, the application and integration system can be run across Windows, Linux, and Mac environments to support broader use of multi‐source agrometeorology data.

Biogas purification using cellulose nanocrystals/polyvinyl alcohol coated facilitated transport hollow fiber membranes with L‐arginine as CO2 carrier
Authors: Nithin Mithra S. , Ahankari Sandeep S. 
Published: October 2024

AbstractThe composition of biogas consists mainly of CH4 (~60%) and CO2 (40%). To be considered a clean fuel, CH4 concentration in biogas must be increased to over 95%. In this study, membranes which were stacked in a chamber were utilized to purify biogas by passing biogas over them. These membranes were composed of polyethersulfone hollow fiber substrate coated with a “selective layer” made of cellulose nanocrystals (CNC‐0–2 wt) in polyvinyl alcohol (PVA) and l‐arginine as a CO2 carrier. Of the different CNC concentrations in PVA‐LA, CNC1/PVA‐LA (1.0 wt% CNC in PVA‐LA) displayed the lowest water contact angle of 17° (corresponding to higher moisture absorbing ability). With further increase in CNC concentration, even though CNC1.5/PVA‐LA showed the higher crystallinity (66%), and water contact angle increased (20°); reducing the chances of facilitated transport of CO2 through it. Biogas separation experiments were conducted at 90% RH and different feed pressures (0.8–1 bar) for various CNC concentrations. Increasing the CNC concentration led to a thicker selective layer, enhancing the CO2 permeability and selectivity up to CNC1/PVA‐LA. However, with the further addition of CNC, both permeability and selectivity decreased. At 90% RH and 1 bar feed pressure, the CNC1/PVA‐LA setup demonstrated a CO2 permeability of 20,522 Barrer and a selectivity of 33, making it suitable for low‐pressure biogas storage systems with lower energy requirements.

Efficient synthesis of 2,5‐furandicarboxylic acid from corncob biomass using Ru/C and sulfonated carbon catalysts in a one‐pot system
Authors: Xu Chao , Cai Jiawei , Shi Weijian , Cui Lijuan , Wu Shuping 
Published: October 2024

AbstractThis study proposes a novel one‐pot method to produce 2,5‐furandicarboxylic acid (FDCA), which effectively simplifies the preparation process of FDCA by directly utilizing the biomass raw material corncob and its derived carbon‐based catalysts. In this work, we first prepared two different carbon‐based catalysts from corncobs: a ruthenium‐supported catalyst (Ru/C) and a sulfonated carbon catalyst. After detailed characterization and performance testing, these two catalysts were used to catalyze the pretreated corncob mixture to produce FDCA. Under optimized conditions, even using 0.12 g of Ru/C catalyst at a microwave power of 200 W, the yield of FDCA can reach 27 mol%. In comparison, the FDCA yield of the sulfonated carbon catalyst under the same conditions was 19 mol%. This work not only demonstrates the possibility of efficient production of FDCA by utilizing biomass resources and a simplified chemical conversion process, but also highlights the importance of selecting appropriate catalysts and controlling reaction conditions in improving yields. Through this method, we can promote the development of biomass conversion technology in a more efficient and environmentally friendly direction, providing technical support for the commercial production of bio‐based chemicals.
Optical Activities of Organic Crystals: Crystal Orbital Formulation of Anisotropic Gyration
Authors: Hatanaka Masashi 
Published: October 2024

ABSTRACTTo describe the optical activities of crystals, gyration tensors are necessary for all wavelengths of incident light. To date, few studies on direct calculations of gyration tensors from Bloch states have been conducted. Herein, a practical procedure to obtain gyration tensors of organic crystals is presented using the crystal orbital method. The extended Hückel method was adopted to evaluate the gyration tensors, epitomizing the one‐electron formulation. To confirm the validity of the formulation, the optical rotatory power of alanine and γ‐glycine was examined. The reproduced profiles of the optical rotatory power were consistent with the results of recent experiments. This is a general formulation of the one‐electron theory of optical activities for three‐dimensional crystals. In principle, the optical rotatory strength tensor is not invariant with translation. For systems with small unit cells, however, the formalism is quasi‐invariant with respect to translation. The quasi origin‐independent formalism is sufficiently substantial to be applicable to modern crystal optics.

ABSTRACTThe current study exploited cheese whey supernatant (CWS) as a renewable resource for polyhydroxyalkanoates (PHAs) formation. Structure identification and investigating the influence of lipid membranes' chemistry on PHA structuration were detailed. Approximately 66 bacterial isolates from dairy products companies in Egypt were screened for PHA production, and the bacterial isolate AZU‐A5, identified as Bacillus licheniformis strain AZU‐A5, showed the highest production PHA 0.93 g L−1) using whey lactose. The highest PHA rate in the individual design was 1.59 g L−1 with a recovery yield of 33.08% (w w−1), while the production rate in the statistical design reached 1.75 g L−1 PHA and 51.60% PHA content. Structurally, the PHA was identified as polyhydroxy‐3R‐butyrate (R‐PH3B). The fibrous texture by SEM highlighted the self‐assembly of PHB. The CD analysis of the PHA films suggested favorable hydrophobic interactions between lipids and PHB. Higher lipid contents not only caused a decrement in the CD signal of PHB but also bathochromic effects occurred. The chain length of lipids exerted high impacts on interactions (CD) and structuration of PHB (Δλ). The unsaturation showed little influence on CD and negligible effect on Δλ, while the head group exerted no effect on CD with a considerable impact on Δλ.
Firm ownership and ESG performance in European agri‐food companies: The mediating effect of risk‐taking and time horizon
Authors: Gega Megi , Höhler Julia , Bijman Jos , Oude Lansink Alfons 
Published: October 2024

AbstractThe environmental, social, and corporate governance (ESG) performance of European agri‐food companies is crucial amidst sustainability challenges. Employing property rights and agency theory, we investigate the influence of firm ownership structure on ESG performance, and the mediating role of risk‐taking and time horizon. A recursive system of equations is employed to test the model using data from 936 European firms. The findings indicate that investor‐owned firms (IOFs) outperform family firms and cooperatives in terms of ESG performance. Family firms demonstrate a longer time horizon, while IOFs exhibit greater risk‐taking. Risk‐taking and time horizon are positively and negatively associated with ESG performance, respectively. However, we find no evidence of a mediation effect. This paper contributes to the agency and property rights literature by exploring the implications of ownership structure for other firm characteristics and ESG performance, and outlines implications for policymakers and managers in the development of focused interventions towards sustainability.
Apathy and effort‐based decision‐making in Alzheimer's disease and subjective cognitive impairment

Published: October 2024

AbstractINTRODUCTIONApathy is a significant feature in Alzheimer's disease (AD) and subjective cognitive impairment (SCI), though its mechanisms are not well established.METHODSAn effort‐based decision‐making (EBDM) framework was applied to investigate apathy in 30 AD patients, 41 SCI participants, and 55 healthy controls (HC). Data were analyzed using a drift‐diffusion model (DDM) to uncover latent psychological processes.RESULTSSCI participants reported higher apathy than AD patients and HC. However, informant reports of apathy in AD patients were higher than self‐reports and indicated significant apathy compared to HC. Both the AD and SCI groups showed reduced sensitivity to effort changes, linked to executive dysfunction in AD and apathy in SCI. Increased resting functional cortical connectivity with the nucleus accumbens (NA) was associated with higher apathy in SCI.DISCUSSIONThese results highlight a similar disruption of EBDM in AD and SCI, differentially related to executive functioning in AD and apathy in SCI.Highlights
This is the first study investigating apathy using an effort‐based decision‐making (EBDM) framework in Alzheimer's disease (AD) and subjective cognitive impairment (SCI).
Self‐reports underestimate apathy in AD patients when compared to informant reports and healthy controls (HC). SCI participants, in whom self and informant reports were more concordant, also showed higher degrees of apathy.
Both AD and SCI groups showed reduced sensitivity to effort.
Reduced sensitivity to effort correlates with executive dysfunction in AD and apathy, but not depression, in SCI.
Increased nucleus accumbens (ventral striatum) connectivity with the frontoparietal network was associated with higher apathy scores in SCI.
The results thus suggest that while AD and SCI can have similar deficits in EBDM, these deficits correlate with distinct clinical manifestations: executive dysfunction in AD and apathy in SCI.

Published: October 2024

ABSTRACTRaman spectroscopy, a robust and non‐invasive analytical method, has demonstrated significant potential for monitoring biopharmaceutical production processes. Its ability to provide detailed information about molecular vibrations makes it ideal for the detection and quantification of therapeutic proteins and critical control parameters in complex biopharmaceutical mixtures. However, its application in Saccharomyces cerevisiae fermentations has been hindered by the inherent strong fluorescence background from the cells. This fluorescence interferes with Raman signals, compromising spectral data accuracy. In this study, we present an approach that mitigates this issue by deploying Raman spectroscopy on cell‐free media samples, combined with advanced chemometric modeling. This method enables accurate prediction of protein concentration and key process parameters, fundamental for the control and optimization of biopharmaceutical fermentation processes. Utilizing variable importance in projection (VIP) further enhances model robustness, leading to lower relative root mean squared error of prediction (RMSEP) values across the six targets studied. Our findings highlight the potential of Raman spectroscopy for real‐time, on‐line monitoring and control of complex microbial fermentations, thereby significantly enhancing the efficiency and quality of S. cerevisiae‐based biopharmaceutical production.

AbstractThis study investigates the combustion behavior, emissions, and aerosol production of four plant species: Laurus nobilis, Cistus monspeliensis, Photinia fraseri, and Cupressus sempervirens. The Heat Release Rate (HRR) and Smoke Production Rate (SPR) were measured, revealing that Cupressus sempervirens had the highest HRR and longest flame duration due to its higher bulk density. Emission Factors (EFs) for key compounds such as CO₂, CO, NO, and aerosols showed significant variation by species. Aerosol analysis indicated that the combustion of all plants primarily emitted fine particles, with the majority being ultrafine particles (PM0.1), particularly in the 25–130‐nm range. Particle size distributions were bimodal in number but monomodal in volume. These findings highlight the impact of plant characteristics on fire behavior and emissions, with significant implications for understanding fire dynamics in wildland–urban interfaces.
Formulation and Recycling of a Novel Electrolyte Based on Bio‐Derived γ‐Valerolactone and Lithium Bis(trifluoromethanesulfonyl)imide for Lithium‐Ion Batteries

Published: October 2024

AbstractThis work introduces a novel electrolyte comprising lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt dissolved in bio‐based γ‐valerolactone (GVL) for lithium‐ion batteries (LIBs). Moreover, a simple and sustainable aqueous‐based recycling approach for recovering the imide‐based lithium salt is proposed. Beyond the sustainable origin of the GVL solvent, this electrolyte exhibits reduced flammability risk, characterized by a flash point of 136 °C, along with favorable transport properties (conductivity of 6.2 mS cm−1 at 20 °C) and good electrochemical stability (5.0 V vs Li+/Li). Its good compatibility with graphite and lithium iron phosphate electrodes ensures remarkable cycling stability in LIB full‐cells after 200 galvanostatic cycles at 1 C. Furthermore, the proposed liquid–liquid phase electrolyte recycling method allows for a nearly complete recovery of the LiTFSI salt (97–99%) and the GVL solvent (78%). The feasibility of the recycling process is validated by the reutilization of the recovered LiTFSI salt in electric double‐layer capacitors, achieving performances similar to that of the pristine salt with exceptional long‐term stability.
Janus‐Architectured Lithium Replenishment Separators Boosting Longevity of Anode‐Free Lithium Metal Batteries

Published: October 2024

AbstractAddressing the issue of inactive dead lithium deposition on the anode side remains a significant challenge for anode‐free lithium metal batteries. While lithium compensation techniques can mitigate lithium depletion, directly introducing lithium compounds into the cathode material may degrade the electrode structure. Here the design and fabrication of a novel lithium replenishment separator (LRS) using a lithium compensation agent of Li2C4O4 is reported. The electrospun LRS demonstrates excellent ionic conductivity of 1.82 mS cm−1 and a high Li+ transference number of 0.51. Such a functionalized LRS not only provides additional active lithium for anode‐free lithium metal batteries but also promotes uniform deposition of lithium metal. Compared with conventional polyolefin‐based separators, the LRS effectively boosts LiFePO4||Cu anode‐free batteries with enhanced cyclability. These results suggest this LRS strategy can find promising applications in next‐generation anode‐free batteries with high energy densities.

Published: October 2024

AbstractThis research delves into the intricate relationship between cryptocurrencies and systemic risk within the framework of global financial markets. Utilizing a comprehensive dataset that amalgamates relevant indices from the cryptocurrency market along with global equity indexes from Europe, the United States, and China, the study employs a VAR for VaR model. This approach allows for the computation of spillover effects at different risk quantiles, offering insights into both downside and upside risk scenarios. The analysis underscores the notable spillover between cryptocurrency and traditional financial markets, revealing a complex interplay of risk factors that are not confined to geographical or asset-class boundaries. Our findings suggest that these interconnections could have far-reaching implications for global financial stability, regulatory policies, and risk management practices. By shedding light on these underexplored dimensions of financial markets, this study contributes to a deeper understanding of the systemic risks introduced by the growing prominence of cryptocurrencies.
Quiver tails and brane webs
Authors: Franco Sebastián , Rodríguez-Gómez Diego 
Published: October 2024

Abstract
A new type of quiver theories, denoted twin quivers, was recently introduced for studying 5d SCFTs engineered by webs of 5-branes ending on 7-branes. Twin quivers provide an alternative perspective on various aspects of such webs, including Hanany-Witten moves and the s-rule. More ambitiously, they can be regarded as a first step towards the construction of combinatorial objects, generalizing brane tilings, encoding the corresponding BPS quivers. This paper continues the investigation of twin quivers, focusing on their non-uniqueness, which stems from the multiplicity of toric phases for a given toric Calabi-Yau 3-fold. We find that the different twin quivers are necessary for describing what we call quiver tails, which in turn correspond to certain sub-configurations in the webs. More generally, the multiplicity of twin quivers captures the roots of the Higgs branch in the extended Coulomb branch of 5d theories.
