Summary: Low and intermediate frequency ultrasound were studied for their efficiency on cell destruction and metabolites extraction of the microalga T. suecica. Low frequency ultrasound at high power induced a coiling up phenomenon of the cell walls, allowing the extraction of proteins and carbohydrates. Low power ultrasound at short times enabled protein extraction through cell perforation without destruction. However, the use of 100 kHz frequency resulted in lower yields of metabolites and minimal cell destruction.

Summary: In this study, flower-like carrageenan-silver nanoparticles (c-AgNPs) were synthesized through a green hydrothermal reaction. The reduction of silver nitrate to c-AgNPs was confirmed by the change in color of the solution and the presence of a UV-Vis surface plasmon resonance peak. The functional groups in carrageenan were responsible for the reduction and stabilization of the c-AgNPs. The c-AgNPs exhibited a crystalline structure and antibacterial properties, with a flower-like morphology composed of intercrossed and random lamellar petals.

Summary: We report on the fabrication and electrochemical characterization of biodegradable and flexible supercapacitors. These supercapacitors use graphene nanoplates coated coconut fibers as conductive electrodes, an oral electrolyte solution and rice paper as electrolyte and separator. By adding MgTiO3 nanoparticles to the anode, the capacitance and specific energy of the supercapacitors were enhanced. The biodegradable cells exhibited long discharge times and stable output voltage, which have not been observed previously for such supercapacitors.

Summary: This work investigates the structural, morphological, and photocatalytic properties of titanium dioxide (TiO2) and TiO2:NiIn (T-NiIn) coatings fabricated by spin coating. The results show that T-NiIn coatings exhibit higher effectiveness in the degradation of eosin-yellowish (EY) dye under both UV irradiation and solar light, and also show better stability after multiple cycles of reuse. The incorporation of nickel (Ni) and indium (In) in TiO2 coatings offers a feasible strategy to enhance the degradation of EY dye in drinking water.

Summary: This study investigated the antifungal activity of chitosan (Chi) and sodium benzoate (SB) individually or in combination at different concentrations against R. stolonifer. Chi at 2.5% slowed mycelial growth and resulted in fewer spores and less germination. SB at 2.0% showed 98% inhibition of spore formation. However, the combined treatment of Chi-SB inhibited the growth of the fungus in 100% of the evaluated tests. Scanning electron microscopy images showed changes in the development of the mycelium and external morphology of the spores. Therefore, the combined application of Chi-SB is an alternative method to inhibit the growth of R. stolonifer.

Summary: This study presents a flexible and biodegradable supercapacitor made of cellulose and graphene microplates, with enhanced capacitance through the addition of CaLaCo particles. The introduction of CaLaCo increased the specific capacitance by approximately 70% and resulted in a high capacitance retention of 95.8% after 1500 charging/discharging cycles. The redox peaks observed in the cyclic voltammetry curves indicated the storage of charge through redox reactions, with oxygen vacancy defects and Co2+/Co3+ species identified as the main redox centers. The reduction in series resistance and charge transfer resistance promoted ion diffusion/storage and increased the capacitance of the devices. Overall, this study demonstrates the potential of producing sustainable and flexible supercapacitors for use in wearable/portable devices.

Summary: The immobilization of TiO2-SiO2 (TSO) materials on seed mats helps the germination and early growth of tomato plants. Carvacrol loaded on the TSO materials shows a positive effect on germination percentage and shoot length. However, direct deposition of TSO composites on tomato seeds is not suitable for agricultural purposes due to handling difficulties. Plastic seed mats provide a practical system with lower germination but more homogenous growth. The functionalization of triethanolamine and carvacrol in the TSO NPs allows control over germination time and length of root/shoot.

Summary: This study investigated the performance of tin titanate (SnTiO3, SnT) and cellulose-based composites in removing clonazepam (CZP) drug by physical adsorption. The SnTiO3 powders consisted of coalesced grains and nanotubes, while X-ray diffraction analysis showed a mixture of cassiterite and rutile phases. The optimal dosage of SnT for CZP removal was found to be 50 mg/L, achieving 94.3% removal in just 10 minutes. The Cell+SnT composite, with 50 mg of SnT powder, removed a maximum of 80.5% CZP after 180 minutes, increasing to 95.5% with 100 mg of SnT powder. The adsorption capacity of SnT powders was also found to be 6.3 times higher than that of the Cell+SnT composite. The presence of surface defects in the Cell+SnT composites demonstrated their effectiveness as adsorption centers for CZP molecules. This study highlights the potential of eco-friendly and low-cost floatable composites for pharmaceutical contaminant removal, offering advantages over adsorbent powders.
