We evaluated the toxicity of graphite nanoplatelets (GNPs) in model organism Caenorhabditis elegans. The GNPs resulted nontoxic by measuring longevity as well reproductive capability end points. An imaging technique based on Fourier transform infrared spectroscopy (FT-IR) mapping was also developed to analyze spatial distribution inside nematodes. Conflicting reports vitro antimicrobial properties graphene-based nanomaterials prompted us challenge host–pathogen system C. elegans–Pseudomonas...
ZnO micro and nanorods, produced through simple inexpensive techniques, resulted to be strong antimicrobials against Gram-positive bacteria, <italic>in vitro</italic> as well vivo</italic>, by altering cell outer structures like membrane exopolysaccharides.
In the present study commercial Polylactic Acid-based disposable cups and plates were selected for lab scale anaerobic degradability tests. The experiments carried out under thermophilic conditions at different inoculum to substrate ratios test material sizes, specific biogas production associated kinetics evaluated. Maximum was comparable almost all experimental runs (1620 1830 NmL/gTOCPLA) a biodegradation degree in range 86-100% attained. Moreover, physical, chemical microscopical...
Mechanical recycling is a viable option for reducing plastic waste, especially post-consumer waste and scraps from production processes. Biodegradable polymers have gained attention as alternatives to conventional ones, their potential reprocessing using standard techniques before composting needs be explored. This study focused on commercial biodegradable polymer blend which underwent ten extrusion cycles assess the effects of mechanical properties, rheological behavior, thermal stability....
Cellulose acetate waste from eyewear industry is produced in considerable amounts, and its biodegradability not straightforward due to the presence of plasticizers slow kinetics deacetylation reactions. In this work, chemical recycling cellulose coming proposed through hydrothermal treatment with aim acetic acid diethyl phthalate recovery. was first characterized determine acetylation degree which measured be 2.45 amount 30% by weight. Hydrothermal tests were performed batch 10 mL reactors...
Red mud, a main waste of aluminum industry containing high amount Fe2O3 (20–30 %), was used for the first time post-reduction as iron source in hydrothermal liquefaction (HTL) pinewood; aiming to maximize bio-crude yield and quality, exploiting Fe oxidation with water produce in-situ H2. The red mud capacity H2 investigated reducing it hydrochar produced through HTL at 900 °C 3h. catalytic activity biomass decomposition reactions, attributed presence Al2O3, TiO2, SiO2 etc., also assessed...
The viability of anaerobic degradation treatment as an end-of-life option for commercial disposable bioplastic tableware, typically certified compostable, was assessed. Two types polylactic acid-based items were selected and tested under mesophilic conditions (38 °C) 155 days, until reaching a plateau. Advanced chemical characterization the products performed with combination analytical techniques, i.e., microscopy, spectroscopy, thermogravimetry. methods calculating biodegradation degree...
The colonization of microorganisms and their subsequent interaction with stone substrates under different environmental conditions encourage deterioration materials by multiple mechanisms resulting in changes the original color, appearance durability. One emerging alternatives to remedy biodeterioration is nanotechnology, thanks nanoparticle properties such as small size, no-toxicity, high photo-reactivity, low impact on environment. This study highlighted effects ZnO-based nanomaterials two...
Biochar has been used in various applications, e.g., as a soil conditioner and remediation of contaminated water, wastewater, gaseous emissions. In the latter application, biochar was shown to be suitable alternative activated carbon, providing high treatment efficiency. Since is by-product waste pyrolysis, its use allows for compliance with circular economics. Thus, this research aims obtain detailed characterization three carbonaceous materials: an carbon (CARBOSORB NC 1240®) two biochars...
Abstract This study focuses on the synthesis of iron-doped TiO 2 nanoparticles “via solid-state” method, as an alternative to more common doping strategies, with different iron content (0.5, 1.0, 1.5, and 2.0 wt%) using commercial titania Degussa P25 synthesized (sTiO ) via microemulsion method. The samples were characterized by SEM, BET, UV–Vis-DRS, XRD. photocatalytic activity was evaluated in terms methylene blue (MB) degradation aqueous solution under visible radiation (LED lamp 13 W)...
