Luminescent properties of Li(Ga1-xCrx)5O8 (LGCO) phosphors

In this work, we investigate the synthesis of LiGa₅O₈ ceramic powders through a polyvinyl alcohol-based sol-gel technique and their optical properties when doped with high Cr³⁺ concentrations (5, 25 and 50 mol% with respect to the Ga³⁺ sites). The results indicate that the main crystalline phase, LiGa₅O₈, is obtained after calcining the samples at 1000 °C/2 h in a static air atmosphere. Via X-ray photoelectron spectroscopy, Cr is confirmed to exist in its trivalent oxidation state and the evaluation of the optical properties is performed via photoluminescence excited from visible to vacuum ultraviolet energy range and with X-ray excited optical luminescence, indicating the typical Cr³⁺ emission at the near-infrared energy range. The crystal field and Racah parameters are calculated and the influence of Cr³⁺ concentration in the host material indicates luminescence suppression/quenching and a redshift for a higher amount of these ions.     

Microstructural study of asphaltene precipitated with methylene chloride and n-hexane

This work presents a study of the microstructure, molecular structure and elemental composition of asphaltene precipitated from vacuum residue using a solvent mixture. The infrared spectroscopy (FTIR) results show vibration bands of functional groups such as aromatic C-H (4 adj H and 1 adj H) and sulfoxide (C₂SO). Low vacuum scanning electron microscopy (LV-SEM) reveals a highly porous and a smooth surface asphaltene. C, S and V are the main elements identified by energy dispersive X-ray spectroscopy (EDS) analysis, though some variations in concentration were observed between the porous and the smooth surface asphaltene. Transmission electron microscopy (TEM) analysis shows that asphaltenes are constituted by nanometric particles (micelles) of ∼50 nm in diameter. These particles conform agglomerates (flocs) from ∼350 to ∼550 nm in size, some of them in layer arrangement with a tendency to graphitize. These results reveal important information about flocculation processes of the asphaltene.     

Simultaneous Drying and Modification of Properties of Starch Using Vacuum Microwave Treatment

The prospect of modifying starch properties while drying was investigated. Potato starch (18% moisture, dry basis) was vacuum microwave treated for different durations (60 to 600 s) with power ratings of 600, 1,000, and 1,500 W at a reduced pressure of 5,000 Pa (absolute). The drying rate was observed to be partially constant but was accompanied by a curious rise in sample temperature. Under a polarized light microscope, reduction in granule size was noticed, which was confirmed from the bulk density measurements, and this shrinkage may be explained by the loss of constituent water. Water absorption capacity of the treated starch samples was further studied at 55°C. The results showed a sudden increase in the capacity, indicating a reduction in gelatinization temperature of starch. This may be attributed to the change in nature of starch from crystalline to amorphous as shown by X-ray diffractograms and to the cracks developed on the granule surface during treatment seen in the scanning electron microscope images. This modified starch can serve well in the paper and food industry.     

Lamellar structure and effect of Ti2AlC on properties of prepared in-situ TiAl matrix composites

TiAl matrix composites, reinforced with varying Ti₂AlC content levels, were synthesized by vacuum arc melting by use of Ti, Al and graphite powders as raw materials. The effects of varied Ti₂AlC content from 0 to 100 mol% on the phases, microstructures, fracture behaviors and mechanical properties of resulting products were analyzed. Phase transformation was characterized by X-ray diffraction (XRD) and microstructures were measured by scanning electron microscopy (SEM), equipped with energy-dispersive spectroscopy (EDS). Results show that the products are composed primarily of TiAl, Ti₃Al, Ti₂AlC and small amounts of TiC. The unreacted TiC phase is due mainly to evaporation of Al. The Vickers hardness value of TiAl matrix composite was increased by adding Ti₂AlC, while the TiAl/Ti₂AlC composite fracture behaviors were improved in terms of crack deflection, trans-lamellar cracking and extraction of carbide reinforcements.     

Synthesis of Bi2Te3 nanopowders by vacuum arc plasma evaporation

Starting from elemental bismuth and tellurium, bismuth telluride (Bi₂Te₃) nanopowders were successfully prepared by vacuum arc plasma evaporation (VAPE) technique for the first time. The phase composition in the obtained nanopowders is closely related with the Bi:Te atomic ratio in starting precursor. The microstructure and morphology of the samples were characterized via X-ray diffraction (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SAED). Compositional analysis was also carried out by energy dispersive analysis of X-rays (EDAX). The as-synthesized Bi₂Te₃ nanopowders have a rhombohedral crystal structure with lattice parameters a = 4.381 Å and c = 30.310 Å. The average particle size is about 35 nm obtained from TEM and confirmed from XRD results.     

Preparation of porous-structured LiFePO4/C composite by vacuum sintering for lithium-ion battery

The LiFePO₄/C (LFP/C) composite as a cathode material for lithium-ion battery was synthesized by solid-state reaction under vacuum sintering condition (20–5 Pa). The effects of vacuum sintering temperature and time on the phase composition, morphological structure, and electrochemical performance of LFP/C composite were investigated by X-ray diffraction, scanning electron microscopy, galvanostatic charge–discharge cycling test, and electrochemical impedance spectroscopy. The synthetic LFP/C composite possessed uniform particle-size distribution with porous architecture upon sintering at 650 °C for 12 h and thus exhibited the highest discharge capacity and best cycle performance. The complete decomposition of citric acid at a suitable temperature under vacuum condition resulted in the formation of porous structure. Compared with atmospheric argon sintering, vacuum sintering method led to the formation of porous architecture, the porous sample showed excellent cycle performance with less than 2% capacity loss after 80 cycles at 0.2 C, and reached the discharge specific capacity of 87.6 mAh g⁻¹ at 10 C rate, these are better than that of atmospheric argon sintering. The LFP/C composite prepared under vacuum sintering also reduced the optimum sintering temperature by nearly 100 °C compared with that prepared under atmospheric argon sintering.
