This study deals with SiO2–P2O5 powders obtained by sol–gel process, starting from tetraethoxysilane (TEOS) as precursor for SiO2 and either triethylphosphate (TEP) or phosphoric acid (H3PO4) as precursors for P2O5. In the case of samples prepared with H3PO4, TG–DTA data showed an accentuated weight loss associated to an endothermic effect up to about 140 °C, specific for the evaporation of water and ethylic alcohol from structural pores, and also due to alkyl-amines evaporation. Sol–gel samples prepared ...

This study reports on a comparison of how two different groups of people with an amputation view their bodies and perceive how others view them. One group has a history of sport participation, while the other has not. The analysis is based on 14 semistructured interviews with people with amputations: 7 were engaged in sport and 7 were not. The following themes emerged: Body, Prosthesis, Independence, Human Person, and Social Barriers. One could conclude that participation in sport influences how ...

The effect of initial compaction on the sintering of borosilicate glass matrix composites reinforced with 25 vol.% alumina (Al2O3) particles has been studied using powder compacts that were uniaxially pressed at 74, 200 and 370 MPa. The sintering behaviour of the samples heated in the temperature range 850–1150 °C was investigated by density measurement, axial and radial shrinkage measurement and microstructural observation. The density of the sintered composites increased continuously with temperature ...

In the present study, lithogenic/biogenic and anthropogenic elements were determined in five sediment cores collected at the SW Iberian Continental Shelf in order to investigate the spatial and temporal heavy metal distribution and to associate them with specific continental influences/events. Elemental concentrations suggest a heavy metal (Cu, Zn and Pb) enrichment at the upper sections of all the cores. This enrichment is larger for cores localised closer to the coastline and probably exposed to ...

Herpes simplex virus-1 (HSV-1) is a large dsDNA virus that encodes its own DNA replication machinery and other enzymes involved in DNA transactions. We recently reported that the HSV-1 DNA polymerase catalytic subunit (UL30) exhibits apurinic/apyrimidinic and 5′-deoxyribose phosphate lyase activities. Moreover, UL30, in conjunction with the viral uracil DNA glycosylase (UL2), cellular apurinic/apyrimidinic endonuclease, and DNA ligase IIIα-XRCC1, performs uracil-initiated base excision repair. Base ...

The physical, chemical and mineralogical characterisation of the ash resulting from a pulp mill boiler was performed in order to investigate the valorisation of this waste material through the production of added-value glassy materials. The ash had a particle size distribution in the range 0.06–53 μm, and a high amount of SiO2 (∼82 wt%), which was present as quartz. To favour the vitrification of the ash and to obtain a melt with an adequate viscosity to cast into a mould, different amounts of Na2O ...

The aim was to investigate the effect of simulated low-temperature degradation (s-LTD) and hydrothermal fatigue on the degradation of three ZrO2-based dental materials. Lava, IPS, and NanoZr discs were randomly assigned to (1) Control-Storage in distilled water at 37°C; (2) Aging at 134°C for 5 h (s-LTD); (3) Thermocycling in saliva for 30,000 cycles (TF). XRD revealed that ZrO2 m phase was identified in all groups but TF increased the m phase only for Lava. Under the FESEM, Lava showed no alterations ...

Borosilicate glass–alumina composites with (1 − x) Glass + x Al2O3 (x = 0, 5, 10, 25 vol.%) were prepared and the effect of Al2O3 addition on the structural, electrical and thermal characteristics was investigated. XRD patterns revealed the presence of cristobalite (SiO2) in sintered borosilicate glass and that the addition of Al2O3 hinders cristobalite formation. This behavior is due to the diffusion of some Al3+ ions from alumina to glass, which leads to changes in glass structure and composition as identified ...

Barium zinc borosilicate glasses with a molar composition x BaO ‐(60− x ) ZnO ‐30 B 2 O 3 ‐10 SiO 2 , where x ranged from 0 to 60 mol%, were prepared using melt‐quenching method. The effect of BaO substitution for ZnO on the sintering, crystallization, and dielectric characteristics has been investigated. The behavior of the studied barium zinc borosilicate glasses was mainly determined by the relative amount of the structural modifier oxides ( BaO and ZnO ) and the ionic size, and field strength of the modifying ...

A uniform shiny black-coloured glass was obtained using bottom ash produced by a Portuguese municipal solid waste incinerator (MSWI). The bottom ash was the single batch material used in the formation of the glass, which was obtained by vitrification of the solid waste at 1400 °C for 2 h. Under these conditions, a homogeneous melt with an appropriate viscosity to be shaped was obtained, indicating the suitability of this waste material to be employed in the development of vitreous products. The characterization ...

The glass transition and crystallization kinetics of a glass with a molar composition 60BaO-30B2O3-10SiO2 were investigated by differential scanning calorimetry (DSC) under non-isothermal conditions. DSC curves exhibited an endothermic peak associated with the glass transition and two partially overlapped exothermic peaks associated with the crystallization of the glass. The dependence of the glass transition temperature (Tg) and of the maximum crystallization temperature (Tp) on the heating rate was ...

Two glass compositions were prepared from the system SiO2-Li2O-K2O-ZrO2-P2O5 with different SiO2/Li2O ratio (2.39 and 3.39) and the crystallization behavior was investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The crystallization kinetic parameters (activation energy of crystallization and Avrami exponent) were evaluated by different methods from the data obtained by DTA performed at different heating rates. For both glasses, two exothermic ...
