SERS-enabled rapid detection of difenoconazole residues in tomatoes for food safety applications

Abstract Tomatoes are consumed worldwide at high volume, and difenoconazole (DFZ) is extensively applied to protect tomato crops from fungal diseases, making DFZ residue a growing food-safety concern. Surface-enhanced Raman scattering (SERS) provides a rapid and ultrasensitive approach for pesticide monitoring, but most DFZ-related studies rely solely on noble-metal electromagnetic enhancement. Integrating metals with semiconductors...

Biomass-derived iron-coordinated graphene oxide catalyst for efficient synthesis of 5-aryl-1,2,4-triazolidine-3-thiones

Abstract In recent years, the synthesis of new heterocyclic compounds and their derivatives has significantly increased. The 1,2,4-triazolidine-3-thione scaffold has attracted considerable interest because of its potential applications in pharmaceuticals, agrochemicals, and other biologically relevant areas. This study reports a procedure for synthesizing 1,2,4-triazolidine-3-thione derivatives from aldehydes or ketones and thiosemicarbazide at room temperature, using...

Charged Higgs pair production associated with neutral gauge bosons at future multi-TeV muon colliders

Abstract The first results for charged Higgs pair production associated with a neutral gauge boson at future multi-TeV muon colliders are presented within the framework of the Two-Higgs-Doublet Model (THDM). In this phenomenological study, we update the viable parameter space of the Type-X and Type-II THDM. All two-body decay channels of the charged Higgs boson...

A unipotent-nilpotent factorization of matrices over division rings and applications

Abstract We show that every non-invertible square matrix over a division ring D can be expressed as the product of a unipotent matrix and a nilpotent matrix. As an application, we further show that every non-invertible matrix over D can be expressed as the product of at most two matrices that lie in the image of some polynomial in...

Silica-coated nanosized zero-valent iron/persulfate system for sequential reduction–oxidation remediation of subsurface contamination: A feasibility study

Abstract Sequential reduction and oxidation processes are promising for mineralizing recalcitrant contaminants with high oxidation states. The reduction step transforms such contaminants into oxidizable intermediates that are subsequently mineralized in the oxidation step. In this study, we assessed a sequential reduction–oxidation system using silica-coated nanosized zero-valent iron particles (nZVI@SiO2) and persulfate to establish in situ...

Elemental profiling and health risk assessment of Ulva reticulata in a coastal zone of Ninh Thuan Province, Vietnam using ICP-MS technique

Abstract Ulva reticulata is a marine macroalga recognized for its substantial nutritional value and bioaccumulation potential, making it as both a functional food and a sensitive bioindicator for marine monitoring. However, its capacity to sequester trace elements raises critical concerns regarding dietary safety. This study aims to characterize the multi-elemental profile of fourteen Ulva reticulata samples collected from...

A More Ethical Workplace? How and Why Perceived Socially Responsible Human Resource Management Makes a Difference

Abstract Socially responsible human resource management (SRHRM) is a critical component of an organization’s corporate social responsibility (CSR) strategy. It focuses on promoting sustainability goals and creating a positive social environment for employees to observe, learn, and internalize the organization’s ethical values. Drawing on social learning theory, we conducted two separate field studies to investigate...

Pilot Study on the Use of Rheology and Low Field Nmr to Characterize the Liver of Obese Patients Undergoing Metabolic and Bariatric Surgery

Abstract Background and aims. Liver mechanical properties’ (stiffness/viscoelasticity) evaluation is relevant for diagnosing/monitoring liver fibrosis. Due to limitations of the commonly used elastography, we propose the use of rheology and Low Field-Nuclear Magnetic Resonance (LF-NMR). Methods. In 30 liver samples from patients undergoing bariatric surgery and 18 control samples, we evaluated the shear modulus G/critical stress τc (elastic...

Use of low versus high oxygen tension during pre-maturation only in capacitation in vitro maturation (CAPA-IVM): impact on oocyte maturation and metabolism

Abstract Purpose To determine the impact of low versus atmospheric oxygen tension during only the pre-maturation phase of biphasic capacitation in vitro maturation. Methods The study involved sibling oocytes (532 cumulus-oocyte complexes [COCs] from 20 participants [mean age 29.5 ± 2.5 years]) with polycystic ovary syndrome undergoing CAPA-IVM without gonadotrophins. After oocyte pick-up (OPU), COCs were randomized...

Valorization of kombucha fermentation medium for electricity generation in recirculating microbial fuel cells with Shewanella putrefaciens

Abstract Kombucha is a traditional fermented tea rich in organic acids and shows potential as a carbon source for Shewanella species to generate electricity in microbial fuel cells (MFCs). This research investigated the applicability of kombucha post-fermentation medium as a substrate to support the growth of Shewanella putrefaciens and electricity generation in recirculating MFCs. A preliminary growth study showed...
