Polydimethylsiloxane (PDMS) has attracted great attention in various fields due to its excellent properties, but inherent hydrophobicity presents challenges many applications that require controlled wettability. The purpose of this review is provide a comprehensive overview some key strategies for modifying the wettability PDMS surfaces by providing main traditional methods modification and results altering contact angle other characteristics associated with property. Four technologies are discussed, namely, oxygen plasma treatment, surfactant addition, UV-ozone incorporation nanomaterials, as these commonly selected greater availability information, their lower complexity compared new techniques, cost them. Oxygen treatment widely used method improving hydrophilicity introducing polar functional groups through oxidation reactions. addition surfactants provides versatile PDMS, where selection concentration play an important role achieving desired surface properties. effective increasing energy inducing oxidation, generating hydrophilic groups. Furthermore, nanomaterials into matrices represents promising route wettability, adjustable properties dispersion interfacial interactions. synergistic effect such nanoparticles nanotubes, helps improve wetting behaviour energy. present discusses recent advances each technique highlights underlying mechanisms, advantages, limitations. Additionally, trends future prospects importance tailoring ranging from microfluidics biomedical devices highlighted. Traditional often chosen modify because they have more information available literature, less complex than also expensive.

Agricultural spraying, despite modern technological advances, still poses the problem of downwind spray drift, which contributes to environmental contamination and ecological imbalance, are critical sustainability concerns. This study investigated effect lateral wind on different unmanned aerial vehicle (UAV) spraying systems under semi-controlled conditions, additionally evaluating impact four tank-mix adjuvants (drift reduction agents (DRAs)) at varying concentrations effectiveness, droplet size, deposition compared water as a control. By examining UAV-specific dynamics, this research provides insights into sustainable drift strategies that minimize impacts. For UAV performance trials, three UAVs with configurations were tested, TTA M6E, XAG XP2020, DJI T30, identify most effective system for minimizing drift. DRA effectiveness commercially available evaluated utilizing T30 UAV, was chosen because it produces highest proportion fine droplets. The products included an ionic/non-ionic surfactant (DRA No. 1), silicone-based wetting Nos. 2 3), spreader-adhesive 4). showed that, among tested systems, M6E XP2020 performed better in low-wind while more suitable stable target area windy conditions but produced higher quantities droplets prone drifting further. Lateral significantly shown by results, increased speed causing additional up m all systems. also DRAs exhibit potential mitigate improve crop coverage, contributing efficient resource use reduced All either reduce distance 3 or decrease 67% water. However, 1 best results out terms control, 4 coverage adequate control capabilities. More field is required validate real-life application scenarios. In summary, following management measures can be used using order importance: selecting nozzles optimal specific requirements task, planning applications correlation speed, DRAs.

Preventing biofouling in microalgal photobioreactors

Bioresource Technology, Год журнала: 2024, Номер 407, С. 131125 - 131125

Photobioreactors (PBRs) are used to grow the light-requiring microalgae in diverse commercial processes. Often, they operated as continuous culture over months period. However, with time, biofouling layer develops on inner surfaces of their walls. The fouling formation deteriorates PBR performance foulants reduce light penetration it. Light is essential for photosynthetic cultures, and a deterioration lighting adversely impacts algae growth biomass productivity. Fouling requires frequent shutdown clean add environmental impact operation by generating many wastewaters contaminated cleaning chemicals. Antibiofouling coatings could be modify existing future PBRs. Therefore, transparent non-toxic fouling-release coatings, produced using hydrogel technology, transform PBRs into efficient enduring systems, requiring only application coating walls, without additional investments new
