The functionalization of mesoporous silica nanospheres and hybrid core-shell magnetic has been carried out through post-synthetic procedures, these materials have tested as adsorbents for the removal sulfamethoxazole (SMX) diclofenac (DF) from water. effects material types functionalities anchored on surface investigated. Additionally, unreacted silanol groups capped with hydrophobic trimethylsilyl to modify hydrophilic-hydrophobic properties materials. characterized by textural,...
Although paraquat has been banned in European countries, this herbicide is still used all over the world, thanks to its low-cost, high-efficiency, and fast action. Because highly toxic humans animals, there interest mitigating consequences of use, namely by implementing removal procedures capable curbing environmental health risks. This research describes new magnetic nanosorbents composed magnetite cores functionalized with bio-hybrid siliceous shells, that can be uptake from water using...
The presence of several organic contaminants in the environment and aquatic compartments has been a matter great concern recent years. To tackle this problem, new sustainable cost-effective technologies are needed. Herein we describe magnetic biosorbents prepared from trimethyl chitosan (TMC), which is quaternary scarcely studied for environmental applications. Core@shell particles comprising core magnetite (Fe3O4) coated with TMC/siloxane hybrid shells (Fe3O4@SiO2/SiTMC) were successfully...
Doxorubicin is one of the most widely used anti-cancer drugs, but side effects and selectivity problems create a demand for alternative drug delivery systems. Herein we describe hybrid magnetic nanomaterial as pH-dependent doxorubicin release carrier. This nanocarrier comprises iron oxide cores with diameter 10 nm, enveloped in material made siliceous shells ĸ-carrageenan. The possess high loading capacity favorable profile, while allows easy manipulation via an external field. pH...
Copper sulphide nanocrystals of different phases and exhibiting distinct optical properties have been prepared<italic>via</italic>thermolysis single-molecule precursors in ionic liquids aiming at photocatalytic applications.
Bionanocomposites based on chitosan have been explored as magneto-plasmonic nanosorbents for the SERS detection of organic molecules in spiked water.
Abstract Spherical and monodispersed sub‐micrometer sized particles of organic–inorganic hybrids were prepared by means a sol–gel non‐emulsion method using the biopolymer κ‐carrageenan alkoxysilane 3‐isocyanatopropyltriethoxysilane (ICPTES). The structural characterization carrageenan–silica hybrid was performed FTIR spectroscopy solid‐state 29 Si 13 C NMR confirmed that covalently linked to siliceous network via urethane bonds. Zeta‐potential measurements indicate functionalized on surface...
Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most common pharmaceuticals used worldwide. They widely detected in natural waters due to their persistence wastewater treatment, and removal is desirable management. As a contribution tackle this challenge, study explores magnetic quaternary chitosan-based nanosorbents for effective magnetically assisted of three NSAIDs (diclofenac, naproxen, ketoprofen) from water. Toward goal, silane groups were grafted onto backbone trimethyl...
Abstract Transition metal (TM)-modification of silica matrices are found in numerous materials for diverse applications. In other related hybrid materials, one tries to explore properties that result from combining the network with organic moieties, such as covalent grafting polysaccharides onto amorphous nanosilicas. However, sol–gel routes modification TM have been less explored siliceous materials. The present study demonstrates effective (TM = Co 2+ , Ni Cu Zn ) a method uses precursor...
