The high consumption of saturated and trans fats, used in the formulation of lipid-based foods, is associated with incidence of health problems. Organogels or oleogels are a novel class of structured lipids formed from liquid oil as continuous phase entrapped within network of structuring molecu...

Mediterranean calcarenite stones are exposed to several weathering processes related to the climate and environment, producing alteration features conducing to loss of cohesion in their structures. Samples of these building materials were collected from the Spanish Fort of Bizerte (Tunisia) to c...

This work demonstrates for the first time the preparation of interlayer-free silica membranes by the Rapid Thermal Processing (RTP) method at 630 °C using ethyl silicate (ES40) as a silica precursor. RTP resulted in water being retained inside the xerogel pores at higher temperatures, thus favo...

In this study, several aspects of the surface treatment of concrete with ethyl silicate were investigated. After the treatment, two different types of concrete (w/c 0.45 and 0.65) showed a dramatic decrease in capillary suction, chloride diffusion coefficient and carbonation depth. A penetration...

The response to thermal variations is the primary cause of marble deterioration in ancient and modern buildings. In this study, the thermal behavior of Carrara marble after consolidation by an innovative hydroxyapatite-based treatment was investigated in comparison with ammonium oxalate and ethy...

This work reported basically aims at understanding the extent of SiO2-coated carbon nanofibers using two different sol–gel precursors for the silicate glass. The silicate precursors employed were tetraethoxysilane (TEOS) and pre-hydrolysed ethyl silicate. The first route consisted in an acid hy...

Despite the widespread use of ethyl silicate for stone consolidation, the investigation of its reactivity with the different supports is still in progress. In this paper, the pozzolanic behaviour of ethyl silicate is investigated, by means of experimental mixtures of commercial ethyl silicate an...

Two lime mortars were treated under laboratory conditions to assess the potential effectiveness of three consolidation treatments performed with: an ethyl silicate, a nanolime and a solution of barium hydroxide. The consolidation products were applied by direct contact capillarity. The duration ...

In this studied, extracts of black garlic on the improvement of gastrointestinal function, antioxidant activity, total polyphenols, total flavonoids and total polysaccharides were evaluated. Results showed that the black garlic n-butanol fraction extract (BA) had significantly increased effect w...

Black pepper (Piper nigrum), known as “king of spices” is the most widely used spice in the world. Though a number of marketed food grade products are available for black pepper, however, the labels does not mention the quality of active drug Piperine (PPN) and level of toxic elements. The stu...

In this study, we investigate the synthetic tunability of a solvent-free synthesis of crystalline ZSM-5 zeolite. Conventional zeolite syntheses use hydrothermal reactions to facilitate reagent dissolution and atomic level mixing that lead to zeolite crystallization at moderate temperatures near ...

The performance of proton exchange membrane fuel cells (PEMFC) is strongly determined by the structure and composition of the electrode layer. The interactions between the ionomer, carbon black particles, and solvent affect the suspension properties and thus the layer morphology. We analyze the ...

This study investigates the structure-performance relationships in different zeolite-solvent systems that are suitable for microwave-assisted dehydration of food waste-derived fructose to 5-hydroxymethylfurfural (HMF). Different types of zeolites (MFI, BEA, and Y) were examined as acid catalysts...

Formation of conversion coatings involves chemical reactions at the solid/liquid interface. A liquid membrane on Mg and its alloys was adopted to fabricate conversion films based on the hot corrosion reactions at the choline chloride-urea deep eutectic solvent (DES) membrane/substrate interface....

Morphologically controlled hierarchical CuO microstructures were fabricated via facile ultrasound-assisted method and well characterized using several techniques in detail. Morphologies such as chrysanthemum flower, pillow, cotton, rose flowers were obtained upon using different organic solvents...

Solvent-free methods for the synthesis of ZSM-5 have been previously reported in the literature. These methods typically involve grinding the starting materials together prior to the hydrothermal reaction step. However, very little is known about the reaction intermediates formed during the mech...

Lignin is generated as a waste biomass from pulp and paper industry. The majority of kraft lignin is currently combusted as a low-grade energy source. Lignin valorization has been considered a feasible option to sustainable production of chemicals and liquid fuels in the long run. This study rep...

SummaryIn previous papers, cerium and lanthanum based methods for light -microscopical detection of acid and alkaline phosphatase activity were proposed. In this paper, the usefulness of other lanthanide cations such as gadolinium and praseodymium/neodymium cations as capture agents in phosphata...

SummaryThree species of Didymium, D. nigripes, D. difforme and D. squamulosum, have been grown in culture and have produced sporangia on a solid synthetic medium.Some observations on the effect produced by external conditions, more especially by moisture conditions, on the development of sporang...

The extraction of neodymium from didymium nitrate solution (a mixture of 83% Nd, 15% Pr and 2% other rare earths) by quaternary amine (Aliquat 336) was studied in a 45-stage tube-type mixer-settler. Six different banks in the system were used for solvent pretreatment, neodymium-stripping, feed-l...
