To reduce energy consumption, inorganic cementing materials were prepared by solid waste to replace parts of the cement. In this experiment, composite cementing material was prepared by mixing ultrafine fly ash, lime and gypsum; then, this material was hydrated at a calcium-to-silicon (C/S) ratio of 0.6-2.2. The effects of various C/S ratios on the properties of the prepared composite cementing material were investigated. The results showed that when the C/S ratio was 1.6, the compressive and flexural strengths of the composite cementing material reached their maximum. With the increase of C/S ratio, the production of C–S–H gel and ettringite increased; the two products got interwoven, filling the pores of hydration products and increasing the strength of the cementing material. When the C/S ratio was 2.0, the carbonization rate of the cementing materials increased. Calcite coated the surface of the fly ash, preventing the pozzolanic reaction of the fly ash and reducing the overall strength of the material.

In this work, a low thermal expansion glass-ceramic material based on ternary LAS (Li2O-Al2O3-SiO2) system has been prepared by adopting meltquenching route using industrial waste (blast furnace slag) and low-cost aluminosilicate minerals (China clay and pyrophyllite) at relatively low melting temperature (∼1450°C). A part of the precursor powder for pristine glass has also been prepared by sol-gel processing utilizing Li2CO3 and Al(NO3)3.9H2O to obtain better homogeneity in the glass composition vis-à-vis glass-ceramics at lower melting temperature. Thermal properties of the material have been characterized to optimize the nucleation and crystallization temperatures for converting glass to glass-ceramics. Phase structure and surface morphology of the glass-ceramics have been analyzed by X-ray diffraction (XRD) and field emission scanning electron microscopy. XRD study reveals the presence of lithium aluminosilicate as a major phase at the crystallization temperature of 730°C. The developed glass-ceramics show a low thermal expansion coefficient (CTE) value of (19±0.5)×10–7/°C in the temperature range of 30°-500°C. The present work can unfold an avenue towards conversion of waste into wealth in the form of low CTE glass-ceramics for possible application as cook-top plate of LPG gas oven.

In this review, we present the impact of CeO2 nanoparticles on corrosion protective properties; synthesis of CeO2 nanoparticles by a green and chemical process; protective CeO2 coating deposited on the substrate by different methods; CeO2-based orga nic coa tings; CeO2-based in organi c coa tings and tribological behavior of CeO2. Also, it enlightens the influence of grain size, cracking, pore size, microstructure, and micro-hardness on CeO2-based corrosion coatings. Investigations into the effects of corrosion found that CeO2-based coatings had high potential and a drop in current densities, which are responsible for the inhibitory performance. Additionally, the inclusion of CeO2 nanoparticles results in finer-grained deposits with improved corrosion resistance. M ost CeO2 coatings display good corrosion resistance compared to other potential organic and inorganic composite coatings addressed in this section.

Hydrothermal method was used to synthesize magnetite and magnetite-titania nanoparticles, using ferrosulfate heptahydrate and tetraubutyl orthotitanate as magnetite and titania precursors, respectively. X-ray diffractometry and scanning electron microscopy results revealed successful synthesis of spherical (Fe3O4S), cubic (Fe3O4C) and rod-like (Fe3O4R) NPs. Fe3O4C NPs had the highest (66.36 emu.g−1) and Fe3O4R had the lowest (35.11 emu.g−1) saturated magnetism. By depositing titania on the magnetite NPs, saturated magnetism was drastically reduced in the samples. The kinetics of photocatalytic methylene blue (MB) decoloration of the samples followed the first-order model. MB removal efficiency of Fe3O4-TiO2 NPs with spherical, cubic and rod-like magnetite was more than 90, 73 and 64%, respectively, after 120 min irradiation, which shows an excellent improvement compared to similar works. It was interesting that the specific surface area of Fe3O4-TiO2 NPs had a higher influence on photocatalytic activity compared to morphology. The results revealed that Fe3O4C-TiO2 NPs had the highest magnetic saturation, while Fe3O4S-TiO2 NPs had the highest photocatalytic activity. It was found that Fe3O4S-TiO2 NPs had the optimal magnetic and photocatalytic properties, and may potentially be used for wastewater purification.

Firstly, silica aerogel films with various silica sol driptimes were prepared and characterized. According to spectroscopic ellipsometry, therefractive index of an aerogel film with a silica sol drip time of 9 min decreased by5.9% compared with a film with sol drip time of 18 min in the intermediate region ofthe sample. The increase in sol drip time led to an increase in particle size andthickness, and a decrease in pore size. Secondly, four different types of SAW filterswere designed, i.e. covered with either air, poly(dimethylsiloxane) (PDMS), PDMSfilled with silica aerogel powder, or a silica aerogel film. Addition of silica aerogelpowder to PDMS increased the bandwidth of the resulting SAW filter to 2.362 MHz,increased its central frequency to 0.001 GHz and decreased its insertion loss to 1.545dB. Although they had low porosity, the SAW filters covered with silica aerogel filmshad a bandwidth of 60.586 MHz, a central frequency of 2.447 GHz, a Q value of 40.073, and the largest insertion loss of –15.397 dB. SAW filters with silica aerogel films withvarious sol drip times were also tested. The results indicated that more porous thesilica aerogel films, stronger is the signal strength and smaller is the insertion lossof the SAW filter.

The present study is aimed at producing floor tile which incorporated Ahlat stone as an alternative raw material for the ceramic industry. The effects of the increasing amount of Ahlat stone (1, 3 and 5 wt%) in the recipes on slurry rheology, physical properties of ceramic tiles, and sintering were studied. Chemical components of raw materials and Ahlat stone were determined using X-ray fluorescence spectroscopy and accordingly the recipes were created. The surface morphology of tiles was scanned using scanning electron microscope. When 3% Ahlat stone was added to the recipe, the flexural strength was calculated as 540 kgf.cm−2. This value is 22% higher than the value which is specified in the TSE standards. Therefore, tiles with a longer lifetime and more durability were developed. In addition, the increased amount of Ahlat stone in the recipe reduced the sintering temperature, thus energy saving was achieved during firing.

To get an insight to the erosion behavior of the deposited coatings, high temperature solid particle erosion trials on them are carried out as per ASTM G76 considering the test parameter combinations obtained from Taguchi’s L16 orthogonal array. On analyzing the experimental outcomes, impact velocity, NiCr content in the feedstock, erodent temperature and impingement angle are found to be sequentially significant in terms of affecting the wear loss of the coatings. Based on the findings from the analysis, further experimentations are conducted at different levels of the significant control factors to ascertain their effects on the wear rate more precisely.

Here, we perform a computational analysis of COVID-19 spread in three cities of similar size in New York State (Colonie, New Rochelle, and Utica) aiming to isolate urban determinants of infections and deaths. We develop detailed digital representations of the cities and simulate COVID-19 spread using a complex agent-based model, taking into account differences in spatial layout, mobility, demographics, and occupational structure of the population.

Specifically, with highly efficacious testing and detection, the number and capacity of hospitals, as well as the extent of vaccination of hospital employees are key determinants of COVID-19 spread.
