Understanding the Toxicity Effects of Nanostructures: I. Effect of Physico-chemical Properties on Environmentally Relevant Organismal Toxicity. II. Design of Novel Nanostructures to Reduce Environmental Toxicity while Retaining Functional Properties
… to increased entrance into the environment where toxicity can occur to plants and other organisms. The focus of this research is to understand the origin of nanomaterial organismal toxicity and methods for its reduction through engineering. Nano silver, nano carbon, and nano copper were chosen as …

Investigating structure and chemistry in functional ferroelectric ceramics via transmission electron microscopy
… of lead-based materials in devices, owing to its environmental toxicity. The second system is the improper ferroelectric, CsNbW2O9, which has been studied for its potential application in the field of domain wall nanoelectronics. This field has developed as a result of the discovery of conducting …

AMPHOTERIC POLYAMIDOAMINES AS FUNCTIONAL SPECIALTY POLYMERS
… The first one was to evaluate the potential environmental impact of amphoteric water-soluble PAAs, which may accidentally be released into ecosystems during or after their useful life. The ecotoxicity of PAAs was evaluated on the early stages of plant development using Lepidium sativum …

Novel Approaches for Anthelmintic and Nematicide Discovery
… the phase-out of effective nematicides due to environmental toxicity and human safety concerns necessitates the discovery of new chemical controls for parasitic nematodes with novel targets and modes-of-action. The free-living nematode Caenorhabditis elegans has been an important model for …

Solvent-based self-healing polymeric materials
… system, including catalyst availability, cost, environmental toxicity, stability, and materials processing, motivated the search for a simpler approach to self-healing. Many chemical reactions require the use of a solvent. When an organic solvent is introduced into polymer systems, the mobility …

Self-healing of high temperature cured epoxy and composites
… catalyst stability and availability, cost, environmental toxicity, and difficulties in materials processing, have limited applications in low-temperature cured polymer matrices. Initially, self-healing epoxy adhesives were developed using a proven healing system - encapsulated …

The organization and evolution of heterochromatin in the Anopheles gambiae complex
… still have risks that include insect resistance, environmental toxicity, human health, as well as animal health. In order to develop new strategies that either produce novel targeted insecticides or transgenic mosquitoes that can replace current mosquito populations, it is important to acquire as …

Characterisation and environmental effects of unresolved complex mixtures of hydrocarbons
… prior to oxidation. As an investigation of the environmental toxicity of UCMs, the effect of a saturated aliphatic UCM, and its chemical oxidation products, on the feeding rate of mussels (Mytilus edulis), was investigated. The UCM had little effect, whilst oxidation resulted in an increase in …
