This study aims at the transformation of the waste lignocellulosic biomass, Simarouba glauca seed shell obtained from biofuel industries, into a value-added adsorbent for the removal of dyes from aqueous media. The basic dye direct red (DR) 12B was adsorbed using chemically (ZnCl) and thermally activated Simarouba seed shell carbon (ZASRC and SRC, respectively). Dye removal in batch mode was studied by evaluating adsorbent dosage, contact time, pH, adsorption isotherm and kinetics. Enhanced adsorption of DR12B was attained within 80 min at pH 5 with the maximal adsorption capacity (Q) of 17.48 and 64.94 mg g, for SRC and ZASRC, respectively. Further, the dye removal followed Freundlich isotherm model and pseudo second-order kinetics. The mean-free energy of adsorption demonstrated that dye adsorption onto ZASRC occurs through ion-exchange. Thus, ZASRC can be safely and easily applied for the removal of direct red 12B from aqueous solutions.

Tunable optical properties exhibited by semiconductor nanocrystals (NCs) in the near infrared (NIR) spectral region are of particular interest in various applications, such as telecommunications, bioimaging, photodetection, photovoltaics, . While lead and mercury chalcogenide NCs do exhibit exemplary optical properties in the NIR, Cu-In-Se (CISe)-based NCs are a suitable environment-friendly alternative to these toxic materials. Several reports of NIR-emitting (quasi)spherical CISe NCs have been published, but their more complex-shaped counterparts remain rather less explored.

Plant internal phosphorus (P) recycling is a complex process, which is vital for improving plant P use efficiency. However, the mechanisms underlying phosphate (Pi) release from internal organic-P form remains to be deciphered in crops. Here, we functionally characterised a Pi-starvation responsive purple acid phosphatase (PAP), GmPAP23 in soybean (Glycine max).

This study provides a comprehensive investigation of antimicrobial additives (ZnO/AgNPs and SiO/AgNPs) on the properties of biodegradable ternary blends composed of poly(hydroxybutyrate) (PHB), poly(lactic acid) (PLA), and polycaprolactone (PCL) by examining the morphology, thermal stability, crystallinity index, and cell viability of these blends. Overall, transmission electron microscopy (TEM) analysis revealed that AgNPs and SiO exhibited comparable sizes, whereas ZnO was significantly larger, which influences their release profiles and interactions with the blends. The addition of antimicrobials influences the rheology of the blends, acting as compatibilizers by reducing the intermolecular forces between biopolymers.

In this work, we synthesize a quinoline-based heptamethine cyanine, QuCy7, with sulfonate groups to enhance water solubility. This dye demonstrates exceptional near-infrared absorption beyond 750 nm, accompanied by photothermal properties but low photostability. Encapsulating QyCy7 with polyethylene glycol to form nanopolymer, QuCy7@mPEG NPs, addresses the issue of its photoinstability.
