Here, we report a luminescent cathode buffer layer (CBL) for power conversion efficiency (PCE) enhancement of organic solar cells (OSCs). ZnO doped with Aluminum (Al) and Europium (Eu) was cast as CBL by a solution-processed method. CBL serves a dual purpose by acting both as a spectral conversion and an electron transporting layer. The luminescent...
© 2019 Society of Plastics Engineers This study presents a multiscale analysis for describing the fluid diffusion in polymeric sandwich composites, comprising of glass-epoxy fiber reinforced polymer (FRP) skins and polyurethane foam core. The multiscale framework includes the unit-cell micromechanics model for determining the overall diffusion beha...

In this study, the effect of two water reducer polymers on the thermal stability, rheology, and compressive strength of Gasin Ordinary Cement (GC) was investigated. The behavior of cement in the liquid phase (slurry) and hardened phase modified with two types of polymer varied from 0 to 0.06% (%wt) were investigated. XRD and TGA tests were conducte...
Buildings contribute to 30% of global CO2 emissions and consume 40% of the global energy supply (Yang et al., 2014). Heating and cooling requirements of the buildings form the major part of the energy consumption in buildings (Culha et al., 2015). Thus to solve this problem, one of the solutions currently being
looked at is to recover heat from the ...
Copyright © 2019 American Chemical Society. The thermodynamics of block copolymer/salt mixtures were quantified through the application of Leibler's random phase approximation to disordered small-Angle X-ray scattering profiles. The experimental system is comprised of polystyrene-block-poly(ethylene oxide) (SEO) mixed with lithium bis(trifluorometh...

Hexamethoxymethylmelamine (HMMM) is a crosslinker of melamine resins and widely used in the production of coatings and plastics, e.g. for cans, coils and automobiles. Despite its widespread application little is known about the occurrence of HMMM in municipal wastewater, the extent of its removal in wastewater treatment and the fate of transformati...
Viscosity-modifying agent (VMA) are used in several applications of concrete, such as underwater con-crete, Self-Compacting Concrete (SCC) or Self-Levelling Underlayments (SLU) in order to improve thewashout resistance and the stability. The study focuses on the modifications of cement pastes propertiesimplied when a VMA (hydroxypropyl guars or HPG...
© 2019 Elsevier B.V. Cancer is the major cause of mortality and morbidity throughout the world where >10 million patients with new cases diagnosed every year. The objective of this study was to prepare and evaluate erlotinib loaded chitosan nanoparticles for their anticancer potential. Also, to study the effect of various formulation variables on p...
Supraparticles (SPs) assembled from smaller colloidal nanoparticles can serve as depots of therapeutic compounds and are of interest for long-term, sustained drug release in biomedical applications. However, a key challenge to achieving temporal control of drug release from SPs is the occurrence of an initial rapid release of the loaded drug (i.e.,...
