Pesticide Residue Monitoring on South African Fresh Produce Exported over a 6-Year Period.

open access: yesJournal of Food Protection, 2016
Six years of pesticide residue data from fresh produce destined for the export market were analyzed for the period 2009 to 2014. A total of 37,838 fruit (99.27%) and vegetable (0.73%) data sets analyzed for the presence of 73 pesticides were compared ...

Precision‐Engineered Plasmonic Nanostar Arrays for High‐Performance SERS Sensing

open access: yesAdvanced Optical Materials, EarlyView.
Highly ordered and dose‐controlled arrays of gold nanodiscs are created using the dots‐on‐the‐fly EBL technique and subsequently converted into nanostar arrays. This technique unlocks the reproducible and robust fabrication of highly efficient SERS substrates. Abstract Surface‐enhanced Raman scattering (SERS) spectroscopy has emerged as a powerful tool

The Role of Porosity in SERS

open access: yesAdvanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Solvent‐Free Mechanocatalytic Reduction of Nitro Compounds with Hydrogen Gas and its Application in the Synthesis of Drugs and their Intermediates

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A solvent‐free mechanochemical reduction of nitro compounds using hydrogen gas is presented. In addition to enabling the synthesis of a variety of functionalized aniline derivatives, the method has been scaled up to gram quantities, evaluated for trace metal impurities, and applied to the synthesis of pharmaceutical compounds and their precursors.

Assessment of Pesticide Residue Levels in Vegetables sold in some Markets in Lagos State, Nigeria

open access: yes, 2017
This study investigated pesticide residue levels in the two vegetables commonly eaten in Lagos state Nigeria. The vegetables ( Telfairia occidentalis and Celosia argentea ) were purchased from six markets (Oyingbo, Mile 12, Mushin, Ajah, Agege and Festac)

Microwave‐Assisted One‐Pot Synthesis of Alkyl Levulinates From Post‐Harvest Vegetable Waste

open access: yesAdvanced Sustainable Systems, EarlyView.
Vegetable waste is valorized through Soxhlet extraction using H₂O₂ and heteropolyacid (HPA), followed by material characterization (XRD, FTIR, TGA, DSC). A microwave‐assisted reaction at 170 °C for 30 min with HPA and alcohol yields bio‐based esters.

Chitosan-oligosaccharide alleviates chlorpyrifos-induced biochemical and developmental toxicity and reduces its accumulation in wheat (Triticum aestivum L.)

open access: yesEcotoxicology and Environmental Safety
Chlorpyrifos (CHP) contamination affects agricultural land and poses significant risks to plants and humans. Chitosan-oligosaccharide (COS) enhances plant resilience under stress and boosts the activity of enzymes metabolizing exogenous substances.

Insect‐Microbe‐Based Laccase: Untapped Natural Resource for Industrial and Biotechnological Applications

open access: yesAdvanced Sustainable Systems, EarlyView.
The insect‐microbe interplay fulfills a key ecological role involving the degradation of ligninocellulose biomass. This is coordinated by the secretion of different kinds of proteins, of which ligninolytic enzymes, such as laccases (Lacs), are of prime importance.
