N-compounds speciation analysis in environmental samples using ultrasound-assisted solid-liquid extraction and non-chromatographic techniques Abstract: A fast, efficient, and non-chromatographic method was presented in this study for nitrite, nitrate, and p-nitrophenol (N-compounds) extraction and speciation analysis […]
Towards a white-emitting phosphor Ca10V6O25 based material Abstract: To achieve a stable material capable of white-light emission, we fabricated Ca10V6O25 by both co-precipitation (CP) and microwave-assisted hydrothermal (MAH) methods at different temperatures. The effects of […]
Experimental and ab Initio Studies of Deep-Bulk Traps in Doped Rare-Earth Oxide Thick Films Abstract: Lanthanum-doped CeO2 is a promising semiconductor for gas sensing. A combined study applying impedance spectroscopy and first-principles calculations was performed […]
Morphological aspects and optical properties of Ag4P2O7 Abstract: The structural, morphological and optical properties of silver pyrophosphate (Ag4P2O7) powders were investigated in detail. This material was synthesized by chemical precipitation (CP), conventional hydrothermal and microwave-assisted hydrothermal. […]
Identification of Common Resonant Lines in the EPR Spectra of Melanins Abstract: Melanins are natural pigments with promising bioelectronic applications. Among their unique properties, the existence of a persistent paramagnetic signal can be considered one of […]
Low temperature micro Raman and laser induced upconversion and downconversion spectra of europium doped silver tungstate Ag2-3xEuxWO4 nanorods Abstract: All the red emitting europium-doped silver tungstate alpha-Ag2-3xEuxWO4 (x = 0.01-0.08 mol) phosphor reported herein crystalise as […]
Fingerprints of short-range and long-range structure in BaZr1-xHfxO3 solid solutions: an experimental and theoretical study Abstract: A microwave-assisted hydrothermal method was applied to synthesize BaZr1-xHfxO3, (BZHO) solid solutions at a low temperature, 140 degrees C, and […]
A large red-shift in the photoluminescence emission of Mg1-xSrxTiO3 Abstract: In this letter, we report a detailed study of the influence of the synthesis and the optical properties of Sr-doped MgTO3 powders synthesized via a polymeric […]
Facile Microwave-Assisted Synthesis of Lanthanide Doped CaTiO3 Nanocrystals Abstract: This article discusses a simple approach for the microwave-assisted synthesis of good quality nanosized calcium titanate crystals doped with trivalent Tm and Yb lanthanide ions. The prepared […]
