Electrical response of polymer functionalized ultrafine inorganic particles under frequency conditions: an <i>in situ</i> approach

A Direct Approach to Organic/Inorganic Semiconductor Hybrid Particles via Functionalized Polyfl uorene Ligands

whereas polymer particles containing single QDs are of particular interest for quantum photonic applications. The latter benefi t from an increase in the long-term stability of the embedded QD. [ 10 ] In particular, our motivation is to synthesize nanoparticles from a combination of CdSe QDs with polyfl uorene (PF) [ 11 ] as the conjugated polymer, with the long term aim of a controlled generat...

An Experimental Investigation on Fracture Analysis of Polymer Matrix Composite under Different Thermal Cycling Conditions

Fracture analysis of glass/epoxy composites under different thermal cycling conditions is considered. Temperature difference, stacking sequence, fiber volume fraction and number of thermal cycles are selected as the experimental design factors. The Taguchi method is implemented to design of the experiment and an apparatus is developed for automatic thermal cycling tests. The tensile tests are d...

Formation of Inorganic Submicron Particles under Simulated Pulverized Coal Combustion Conditions

Ultrafine particles in cities.

Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in in...

Potential health impact of ultrafine particles under clean and polluted urban atmospheric conditions: a model-based study

The main goal of this study was to improve the knowledge of ultrafine particle number distributions in large urban areas and also to call the attention to the importance of these particles on assessing health risks. Measurements of aerosol size distributions were performed during 2 weeks, with distinct pollutant concentrations (polluted and clean periods), on the rooftop of a building located i...
