In food industries, the detection of different tastes in low level is required to enhance the quality of products. Recently, 2-D materials and metal–organic framework (MOF) have attracted extensive attention owing to their unique properties, and they can be used in various appl...
The setting of metakaolin-based geopolymer depends on the raw materials and mix proportions. Setting, when material is cured at room temperature, takes about 1 day and is longer than setting time of Portland cement. For the fast setting of geopolymers, some studies increased the...
In this study, bottom ash sand was classified into sizes of 0.15 mm or less, 0.15∼0.6 mm, 0.6∼1.2 mm, 1.2∼2.5 mm, and 2.5∼5 mm by sand size. The results were evaluated with regard to fine dust removal. The bottom ash sand showed hysteresis in the adsorption and desorption...
In this research, we reported the effect of boron addition on the phase-transition temperature of CoPt-B nanoparticles using a sol–gel autocombustion method. Sago starch was used as a chelating agent. From the results, the suitable values of the sago starch concentration, boron...
Strontium ion-substituted calcium phosphate-based ceramic scaffolds enhance osteogenesis. The objective of the present study was to optimize the strontium hydroxyapatite (Sr-HA) and beta tricalcium phosphate (β-TCP) ratio in the fabricated scaffolds to enhance their mechanical s...
The research on harvesting the wasted mechanical energy and using it as a useful energy source has been in the spotlight. Conventional ceramic-based devices have disadvantages such as mechanical brittleness and high-temperature processing. To overcome these weaknesses, the piezo...
A direct utilization of hydrocarbon fuels in solid-oxide fuel cell (SOFC) has been considered a worthwhile and realizable goal. Admittedly, while great strides have been made toward this development goal, there still remain Ni-based anode materials issues to be resolved. In this...
The amount of interstitial oxygen (δ) in Sr-doped lanthanum nickel oxide ( La2–xSrxNiO4+δ) as a function of Sr content has been investigated by the thermogravimetry analysis (TGA) and X-ray photoelectron spectroscopy (XPS). La2–xSrxNiO4+δ (0 ≤ x ≤ 0.5) ceramics were pr...
Soft-hard magnetic composites have attracted much attention as magnetic materials for permanent magnets due to high coercivity and saturation magnetization in various fields such as motor, storage device and magnetic actuators. Hard magnetic materials with low saturation magneti...
The syntheses, crystal structures, thermal decomposition, and optical absorbance spectra of the tantalum-based complex perovskite oxynitrides Ca1/2Sr1/2TaO2N, Sr1/ 2Ba1/2TaO2N, and Ca1/3Sr1/3Ba1/3TaO2N were investigated. Synchrotron X-ray Rietveld refinement showed that Ca1/2Sr1...
Lead-free NKLNTS ceramics with promising piezoelectric properties were fabricated using the solid phase method, which is a general ceramic manufacturing method. MnO2 was added to NKLNTS ceramics as a sintering aid to improve piezoelectric and dielectric properties. The added MnO...
The effect of impurities in coal gangue on the sintering and properties (porosity and compressive strength) of porous cordierite ceramics has been investigated by adjusting the amount of impurities by controlling the acid–gangue ratio during acid leaching. The sintering behavio...
