The catalytic wet oxidation process was used to study the degradation of carbohydrates in wastewater with glucose as a model compound. transition metals Co and Mo were transformed into their insoluble metal oxide forms, Co3O4 MoO3. A novel catalyst prepared by using CuNiIn alloy, which oxidized at 700 °C generate an mixed oxide. Wet reactions performed 150–210 for 60 min 20 bar O2 pressure. per...

A presynthesized, square planar copper imidazole complex, [Cu(imidazole)4](NO3)2, was utilized as a precursor in the synthesis of a new series of zeolitic imidazolate frameworks, termed ZIF-202, -203, and -204. The structures of all three members were solved by single-crystal X-ray diffraction analysis, which revealed ZIF-203 and -204 having successfully integrated square planar units within th...

background: many azoospermic patients with non obstructive azoospermia (noa) are candidate for testicular sperm extraction (tese) and in vitro fertilization. because sperm might be present in some but not all parts of the testes of such men, multiple sampling of testicular tissue are usually necessary to increase the probability of sperm finding. sperm finding can be done by two methods: 1) cla...

Gels are kinds of soft and wet materials, having many unique characteristics such as low friction, material permeability, and biocompatibility. In the last decade, the mechanical weakness of the gels has been overcome by the advent of novel high-strength gels, which promises to expand the industrial and medical applications of the soft and wet materials. Here an optical 3D printer was developed...

Engineering new tissues using cell transplantation may provide a valuable tool for reconstructive surgery applications. Chondrocyte transplantation in particular has been successfully used to engineer new tissue masses due to the low metabolic requirements of these cells. However, the engineered cartilaginous tissue is too rigid for many soft tissue applications. We propose that hybrid tissue e...

This paper aims to describe the nutritional status of Caboclo adolescents living in two areas of the Amazon Basin. Two cross-sectional studies, the first in the dry and the second in the wet season, were carried out in two Amazonian ecosystems: the forest and black water ecosystem, and the floodplain and white water ecosystem. Measurements of weight, stature, arm circumference and triceps, subs...

This work presents the optimization of the operation of a concentrated solar power plant with dry cooling over a year, evaluating the molten salts storage, the power block and the air cooling system as a function of the climate and atmospheric conditions. We locate the plant in the south of Europe, Almería (Spain), due to the high solar irradiation and for comparison purposes with a wet cooling...

Chemical agglomeration can reduce the particulates (including PM2.5) concentration emitted from fly ash particulates and the wet flue gas desulfurization (WFGD) system. However, the calcium-based slurries affect the regulation of agglomeration compared to water, in particular, the wettability of the particulates and the viscosity of the calciumbased slurry. The wettability and the viscosity are...

The Pearl River Delta (PRD) region is one of the most population-dense areas in China. The safety of its drinking source water is essential to human health. Polycyclic aromatic hydrocarbons (PAHs) have attracted attention from the scientific community and the general public due to their toxicity and wide distribution in the global environment. In this work, PAHs pollution levels from the drinki...
