Triazine‐based molecular glasses frustrate the crystallization of barbiturates
(Royal Society of Chemistry, 2019-02-05)
Hydrogen bonding is a key element of supramolecular chemistry and is often used in crystal engineering to direct crystal packing. In particular, systems where motifs with multiple hydrogen (H) bonds are present, such as ...
Polarized raman analysis of polymer chain orientation in ultrafine individual nanofibers with variable low crystallinity
(American Chemical Society, 2018-10-26)
Recent mechanical studies of ultrafine electrospun polymer nanofibers showed they can simultaneously possess high strength and toughness attributed to high degree of chain alignment coupled with low crystallinity. Quantitative ...
Quantifying polymer chain orientation in strong and tough nanofibers with low crystallinity : towards next generation nanostructured superfibers
(American Chemical Society, 2019-04-19)
Advanced fibers revolutionized structural materials in the second half of the 20th century. However, all high-strength fibers developed to date are brittle. Recently, pioneering simultaneous ultrahigh strength and toughness ...
Eumelanin for nature-inspired UV-absorption enhancement of plastics
(Wiley, 2019-02-06)
In the human body, the black-brown biopigment eumelanin blocks the harmful
ultraviolet (UV) radiation. In the plastics industry, additives are often added to polymers to
increase their UV-absorption properties. We herein ...
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 ...
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 ...
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 ...
