Advanced Flexible Wearable Electronics from Hybrid Nanocomposites Based on Cellulose Nanofibers, PEDOT:PSS and Reduced Graphene Oxide
The need for responsible electronics is leading to great interest in the development of new bio-based devices that are environmentally friendly. This work presents a simple and efficient process for the creation of conductive ...
Coupling hydrological and sanitation datasets to simulate wastewater-derived contamination in European rivers: Model development and calibration
Wastewater treatment plant (WWTP) discharges of microcontaminants negatively impact freshwater streams, underscoring the need for accurately mapping wastewater-derived contamination in water bodies across Europe (EU). In ...
Editorial: The Use and Management of Agricultural Irrigation Systems and Technologies
Agricultural irrigation systems help provide food to meet the growing demands of the global population. As a result of climate change, irrigated agroecosystems face threats such as excessive runoff, soil erosion, salinization, ...
Effects of porous media type and nozzle design on the backwashing regime of pressurised porous media filters
Pressurised sand filters used in drip irrigation need periodic backwashing to flush the contaminant particles out of the porous media. This process consumes high amounts of energy and water. The selection of more efficient ...
In-situ synthesis and binding of silver nanoparticles to dialdehyde and carboxylated cellulose nanofibrils, and active packaging therewith
The present work reveals the potential application of dialdehyde and carboxylated nanocellulose for the in-situ reduction of Ag+ and immobilization as silver nanoparticles (AgNPs) on cellulose surfaces. Tollens’ reagent ...
Configuring Socio-Environmental Risks in Chile: Institutional Narratives and Complexities in a Risk Society
Living in a society characterized by risk has distinct implications for developing countries, where addressing the socio-environmental issues within established governance structures is challenging. This study aims to ...
Emulsions, dipsticks and membranes based on oxalic acid-treated nanocellulose for the detection of aqueous and gaseous HgCl2
Although cellulosic materials have been used as stabilizing agents for oil-in-water emulsions since the 1980s, their properties and the underlying mechanism are not universal regardless of the dispersed phase or of the ...
Fit-for-Use Nanofibrillated Cellulose from Recovered Paper
The cost-effective implementation of nanofibrillated cellulose (CNF) at industrial scale requires optimizing the quality of the nanofibers according to their final application. Therefore, a portfolio of CNFs with different ...
An update on control of brown spot of pear
Brown spot of pear is a fungal disease producing high economical losses in several pear-growing areas in Europe. Fungicide applications during the growing period either at fixed schedule or delivered according to the BSPcast ...
Rejection of organic micropollutants from greywater with forward osmosis: A matter of time
Forward osmosis (FO) has popularized lately due to its lower fouling propensity, higher pollutant rejection, and potentially lower energy consumption than other membrane technologies. Greywater (GW) is a good candidate for ...
Advanced control system for reverse osmosis optimization in water reuse systems
A main reverse osmosis (RO) limitation is the operational costs (including energy filtration costs), which are significantly affected by energy costs and the expense of membrane maintenance. Both costs are affected by ...
Water-assisted melt processing of cellulose biocomposites with poly(ε-caprolactone) or poly(ethylene-acrylic acid) for the production of carton screw caps
Composites in 25 kg batches were compounded of cellulose nanocrystals (CNC) and thermomechanical pulp (TMP) and shaped into caps at industrial facilities on a pilot-plant scale. Some of the material was also injection ...
Multicolor PEGDA/LCNF Hydrogel in the Presence of Red Cabbage Anthocyanin Extract
Colorimetric indicator gels were developed by incorporating anthocyanin (AC) obtained from red cabbage into poly (ethylene glycol) diacrylate (PEGDA)-based hydrogel containing lignocellulose nanofiber (LCNF). The PEGDA-based ...
Improvement of the Thermal Stability of Polymer Bioblends by Means of Reactive Extrusion
Poly(lactic acid) (PLA) and biosourced polyamide (PA) bioblends, with a variable PA weight content of 10–50%, were manufactured by melt blending in order to improve the behavior of PLA against thermal degradation. The ...
Application of long-chain ammonium polyphosphate to control inorganic fouling in agricultural saline water distribution systems
The inevitable inorganic fouling in saline water drip irrigation systems (SWDIS) with phosphorus fertilizer has become key obstacle for utilizing saline water and phosphate fertilizer. This study developed a greener ...
Processing Polymer Blends of Mater-Bi® and Poly-L-(Lactic Acid) for Blown Film Application with Enhanced Mechanical Strength
Mater-Bi® is one of the most commercialized starch-based blends used in biodegradable flexible packaging. However, the high ductility and low stiffness of Mater-Bi® might limit its application and developing a solution to ...
Physical, chemical and biological emitter clogging behaviors in drip irrigation systems using high-sediment loaded water
High-sediment water in drip irrigation (HSWDI) technology offers the opportunity to alleviate water shortages in agricultural irrigation. Emitter clogging, caused by active suspended particles, salt ions, and microorganisms ...
Biocontrol of Stemphylium vesicarium and Pleospora allii on Pear by Bacillus subtilis and Trichoderma spp.: Preventative and Curative Effects on Inoculum Production
Trials under controlled and field conditions were conducted to establish the effect of strategies of application of biological control agents (BCAs) in the reduction of Stemphylium vesicarium and Pleospora allii inoculum ...
Feasibility of Barley Straw Fibers as Reinforcement in Fully Biobased Polyethylene Composites: Macro and Micro Mechanics of the Flexural Strength
Awareness on deforestation, forest degradation, and its impact on biodiversity and global warming, is giving rise to the use of alternative fiber sources in replacement of wood feedstock for some applications such as ...
Electrochemical and Microbial Dissection of Electrified Biotrickling Filters
Electrified biotrickling filters represent sustainable microbial electrochemical technology for treating organic carbon-deficient ammonium-contaminated waters. However, information on the microbiome of the conductive granule ...
