TL;DR: In the last two decades, various researchers have worked with a variety of traditional and advanced ceramics such as alumina, zirconia, etc. as mentioned in this paper reported substantial improvements in their properties over conventional products, as well as enhancements in the diffusion and reaction kinetics.
Abstract: Though microwaves have been in use for many applications for over 60 years, their application in ceramic processing involving synthesis, sintering, melting, joining, surface modifications, etc, has developed only in the last twenty years. Microwave materials processing is recognized for many advantages, namely, substantial reduction in cycle time resulting in large energy savings, selective and volumetric heating, providing fine microstructures, improved mechanical properties, and eco-friendliness. In the last two decades, various researchers have worked with a variety of traditional and advanced ceramics such as alumina, zirconia. hydroxyapatites, transparent ceramics, electroceramics, ceramic superconductors, glass-ceramics, non-oxide ceramics including Si3N4, AIN, SiC and WC/Co, etc. In all of these materials, substantial improvements in their properties over conventional products, as well as enhancements in the diffusion and reaction kinetics, were reported. Recently, microwave melting of glasses has ...

TL;DR: The dye-sensitized solar cells (DSSCs) as mentioned in this paper can be considered to be electrochemical devices consisting of a photoanode which has a thick film of a wide band gap oxide semiconductor, typically coated on a transparent conductive oxide (TCO) glass substrate, with TiO2 being sensitized with adsorbed dyes that absorb visible light.
Abstract: The development of dye sensitized solar cells (DSSCs), which have derived inspiration from photosynthesis, has opened up exciting new possibilities and paradigms for producing solar photovoltaics possibly at lower cost. The dye-sensitized solar cells with moderate power conversion (∼10%) efficiencies can be manufactured under regular lab conditions without needing clean rooms or very specialized facilities. The entire processing need not involve even a single vapour deposition step. The DSSCs can be considered to be electrochemical devices consisting of (a) a photoanode which has a thick film of a wide band gap oxide semiconductor (like TiO2), typically coated on a transparent conductive oxide (TCO) glass substrate, with TiO2 being sensitized with adsorbed dyes that absorb visible light, (b) an electrolyte that establishes the internal electrical continuity between anode and counter electrode and mainly plays the role of regenerating the dye such that the photoexcitation, electron injection and current fl...

TL;DR: In this paper, the authors extracted silica aerogel from rice husk ash as sodium silicate by boiling it in sodium hydroxide solution and neutralized with nitric acid to form silica gel.
Abstract: Silica aerogel was prepared from rice husk ash by sol-gel process followed by ambient pressure drying. Silica was extracted from ash as sodium silicate by boiling it in sodium hydroxide solution. Sodium silicate was neutralized with nitric acid to form silica gel. To prepare aerogel, first the pore water of the gel was exchanged by ethanol and then surface modification was done by aging alcogel in tetraethylorthosilicate (TEOS)/ethanol solution. Before drying, TEOS/ethanol solvent was exchanged with n-heptane. Capillary stress and shrinkages were greatly reduced due to the low surface tension of n-heptane. The prepaid aerogel was a light and crack-free solid, with bulk de nsity cf 0.67 g.cm−3, porosity of about 80%, total pore volume of 3.1 cm3.g−1 and specific surface area of about 273 m2.g−1. The nature of surface modification and thermal stability of the aerogel was studied by FTIR and DSC/TG respectively.

TL;DR: In this paper, a series of coupled ZnO-SnO2 photocatalyst was successfully synthesized in the Zn:Sn molar ratio of 20:1, 10: 1, 5:1 and 2:1 via co-precipitation method followed by calcination at different temperatures.
Abstract: A series of coupled ZnO-SnO2 photocatalyst was successfully synthesized in the Zn:Sn molar ratio of 20:1, 10:1, 5:1 and 2:1 via co-precipitation method followed by calcination at different temperatures. The synthesized materials were characterized by X-ray diffraction, diffuse reflectance spectra, scanning electron microscope and transmission electron microscope. Photocatalytic activitiy of synthesized materials was applied for the degradation of cibacron red dye in aqueous solution under UV-A light irradiation. Experimental results revealed that the coupled ZnO-SnO2 photocatalyst with Zn:Sn molar ratio 10:1, calcined at 600oC for 1 h was the most efficient photocatalyst among synthesized samples for the degradation of cibacron red. Superoxide anion radical (•O2–) was found to be the prominent active species responsible for degradation comparative to hole (h+), hydroxyl radical (•OH).

TL;DR: In this article, a review of recent developments in research on the stability, enhancement of thermal conductivities, viscosity and heat transfer characteristics of nanofluids is presented.
Abstract: The ability of conventional fluids to conduct heat is significantly inferior to solids. The motivation to increase fluid thermal characteristics is not a novel idea. Initial experiments involved adding solid particles with more desirable properties to the base fluid under the hypothesis that the overall mixture's thermal behaviour would be more favourable. The recent advance in materials technology has made it possible by producing nanofluids. These are produced by suspending metallic or nonmetallic nanometer-sized solid particles in base fluids. These suspended nanoparticles can change the transport and thermal properties of the base fluid. The aim of this review is to summarize recent developments in research on the stability, enhancement of thermal conductivities, viscosity and heat transfer characteristics of nanofluids. As is evident in this report, extensive research has been carried out in Alumina-water and CuO-water systems besides few reports in Cu-water, and carbon nanotube (CNT) based systems. ...
