Thermal degradation of conventional and nanoencapsulated azoxystrobin due to processing in water, spiked strawberry and incurred strawberry models
(American Chemical Society, 2022-09-21)
Nanoencapsulated formulations of pesticides have been recently developed, and some products are now marketed for specific applications in agriculture. Pesticide residues present in raw agricultural products can degrade or ...
Field evaluation of the potential effects of polymer and silica-based nanopesticides on strawberries and agricultural soils
(Royal Society of Chemistry, 2022-08-18)
Polymeric and SiO2 nanoparticles can be used as nanocarriers to improve the efficacy of pesticide delivery in agriculture. However, the environmental fate and potential risks of this type of nanopesticides in agroecosystems ...
In situ photocontrol of block copolymer morphology during dip-coating of thin films
(American Chemical Society, 2015-09-28)
We demonstrate a unique combination of simultaneous top-down and bottom-up control of the morphology of block copolymer films by application of in situ optical irradiation during dip-coating. A light-addressable and ...
Release of TiO2 nanoparticles from painted surfaces in cold climates : characterization using a high sensitivity single-particle ICP-MS
(Royal Society of Chemistry, 2020)
Paints and coatings represent one of the major applications of TiO2 nanoparticles (NPs). While it has been previously shown that NPs are released from painted surfaces, there is still a lack of experimental data on their ...
Biological impacts of Ce nanoparticles with different surface coatings as revealed by RNA-Seq in Chlamydomonas reinhardtii
(Elsevier, 2020-05-18)
In order to better understand the risks of engineered nanoparticles (ENPs), it is necessary to determine their fate
and biological effects under realistic exposure scenarios (e.g. low ENP concentrations). RNA-Seq was ...
Quantification and characterization of Ti-, Ce- and Ag5 nanoparticles in global surface waters and precipitation
(American Chemical Society, 2021-06-28)
Nanoparticle (NP) emissions to the environment are increasing as a result of anthropogenic activities, prompting concerns for ecosystems and human health. In order to evaluate the risk of NPs, it is necessary to know their ...
Development of an LC-MS-based method to study the fate of nanoencapsulated pesticides in soils and strawberry plant
(Elsevier, 2021-12-04)
The increased production and use of nanopesticides will increase the likelihood of their exposure to humans and the environment. In order to properly evaluate their risk, it will be necessary to rigorously quantify their ...
Eumelanin : from molecular state to film
(American Chemical Society, 2021-02-02)
Eumelanin, a macromolecular biopigment, is an attractive candidate for sustainable (green) organic electronics. Establishing structure–property relationships in eumelanin films is an essential step to exploit its technological ...
Influence of supramolecular interaction type on photoresponsive azopolymer complexes : a surface relief grating formation study
(American Chemical Society, 2016-06-24)
The influence of the supramolecular interaction type—hydrogen bonding, proton transfer, and pure ionic bonding—on photoresponsive behavior, particularly surface relief grating (SRG) inscription, has been investigated using ...
Orientation and partial disentanglement in individual electrospun fibers : diameter dependence and correlation with mechanical properties
(American Chemical Society, 2015-06-29)
Electrospun fibers are versatile materials that exhibit unusual and tunable properties when studied at the single fiber level, including an exponential increase in modulus with a decreasing diameter toward the nanoscale. ...
