Well-defined acid-degradable amphiphilic block copolymers (ABPs) and their nanoassemblies labeled with acid-labile groups have been developed for smart drug delivery, exhibiting controlled/enhanced release of therapeutics in tumoral tissues and endo/lysosomes. In general, controlled polymerization techniques, particularly atom transfer radical polymerizat ...

Due to the oligotrophic marine environment, the lack of phosphorus is one of the key factors limiting the oil biodegradation ability of microorganisms after the oil spill occurs. Overcoming phosphorus deficiency has become an urgent problem. In this study, a phosphate-solubilizing bacteria, named Bacillus subtilis PSB-1, with the crude oil degradation eff ...

Water droplet erosion (WDE) is a critical degradation phenomenon that significantly affects component lifespan and performance in power generation, aerospace, and wind energy industries. The incubation period-the initial phase before visible material loss occurs-is particularly crucial for maintenance planning and material selection yet remains challengin ...

This study investigated the oil pollution remediation ability of konjac glucomannan (KGM) aerogel immobilized Chlorella vulgaris LH-1 (C. vulgaris). The KGM aerogel exhibited a high porosity of 86.83 %, and with the change of crude oil concentration (1-10 g/L), the crude oil adsorption efficiency of KGM aerogel was up to 18.75 %. The KGM aerogel carrier e ...

Per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are persistent environmental pollutants posing significant risks to ecosystems, drinking water safety, and human health. Conventional PFAS removal methods effectively mitigate contamination but face challenges such as high operational ...

The tolerance and degradation characteristics of a marine oil-degrading strain Acinetobacter sp. Y9 were investigated in the presence of diesel oil and simulated radioactive nuclides (Mn2+, Co2+, Ni2+, Sr2+, Cs+) at varying concentrations, as well as exposure to ?-ray radiation (Co-60). The maximum tolerable concentrations for Co2+and Ni2+ were found to b ...

Many processes can contribute to the attenuation of the frequently detected and toxic herbicides atrazine and metolachlor in surface water, including photodegradation. Multi-element compound-specific isotope analysis has the potential to decipher between these different degradation pathways as Cl is a promising tool for both pathway identification and a s ...

External stimuli can trigger changes in temperature, concentration, and momentum between micromotors and the medium, causing their propulsion and enabling them to perform different tasks with improved kinetic efficiencies. Light-activated micromotors are attractive systems that achieve improved motion and have the potential for high spatiotemporal control ...
