One-dimensional microrods (4-5 mm) of PbI2 and CH3NH3PbI3 (MAPbI(3)) with unique structural and morphological properties have been grown at room temperature. X-ray diffraction (XRD) patterns of both types of micro-rods exhibit a hexagonal system (P3m1(164) ...

Colloidal silica nanoparticles (NPs) modified with eight different silane coupling agents were incorporated into an amorphous poly(tetramethylene oxide)-based polyurethane-urea copolymer matrix at a concentration of 10 wt % (4.4 vol %) in order to investig ...

Although supplementary cementitious materials (SCMs) are now commonly accepted and widely used, consensus has not been reached for methods to test their chemical reactivity. A multitude of test methods exist but often fall short on one or more of the key f ...

Perovskite solar cells (PSCs) with mesoporous TiO2 electron transport layers have reached > 22% efficiency at laboratory scale ( < 1 cm(2)), however, these layers are fabricated using spin-coating, which is not conducive to large-scale or high throughput f ...

H-1 nuclear magnetic resonance (NMR) relaxometry, supported by X-Ray diffraction and thermogravimetric analysis, has been used to characterise microstructure of white cement pastes underwater cured at temperatures in the range 10 degrees C to 60 degrees C. ...

Atom transfer radical polymerization (ATRP) of methacrylic acid (MAA) is challenging. Herein is reported a study of conditions for facile surface-initiated ATRP by activator regenerated electron transfer (SI-ARGET-ATRP) growth of poly-methacrylic acid (PMA ...

Thermal energy storage using the effects of the latent heat in the solid-liquid phase transformation has found its way into every day applications. Reusable, organic phase change media stabilize low temperatures of parcels, and salt/water tanks act as buff ...

This thesis investigates the effect of different parameters such as Fe (III), D-gluconate and heterogeneous particles on the nucleation and growth of synthetic C-S-H by using the dropwise precipitation method. Firstly, the effect of Fe (III) on the synthet ...

Polymer brushes are a class of thin coatings, where each of chains is tethered to the underlying substrate via one chain end. Densely grafted polymer brushes feature a stretched chain conformation, which in a unique way enhances their lubrication and non-b ...

Nanocomposites with a high and uniform loading of magnetic nanoparticles are very desirable for various applications. In this study, a simple and scalable route for preparing nanocomposites with a high and uniform loading of magnetic nanoparticles is prese ...

Transparent conductive oxides (TCOs) are semiconductor-like materials that exhibit high electrical conductivity and high optical transparency combined. They are adopted in various applications ranging from gas sensors, to electrochromic windows, to photovo ...

At low pH, underwater adherence between poly(N,N-dimethylacrylamide) hydrogels and poly(acrylic acid) brushes is due to the formation of multiple hydrogen bonds. The effect of the key parameters controlling the formation of these interactions (contact time ...

A novel solid-state electrolyte based on 1,3-dihexylbenzimidazolium ([DHexBIm]) cations combined with Br-, BF4- or SCN- anions is used in CdS/CdSe sensitized quantum dot sensitized solar cells (QDSSCs). A power conversion efficiency of 4.26% was achieved w ...
