Abstract Temporary consolidation is a quite common practice during archeological excavations nowadays. Melts of cyclododecane or menthol are among the most used consolidants. When using melting protocol to consolidate fragile heritages in archaeological excavation sites, one frequently encountered challenges poor penetration melt into heritages, especially cases low environmental temperatures, ...

Interfaces between mica and graphene, as well the transition metal dichalcogenides (TMDCs) MoS2 WS2, were wetted with water ethanol, investigated employing scanning force microscopy molecular dynamics (MD) simulations. Below 25% RH, wets graphene-mica interface labyrinthine structures, exhibiting branch widths of about 50 nm for single layers increasing to almost an order magnitude more four gr...

The synthesis of porous titania microparticles with high specific surface area and sufficient photocatalytic activity is an important but challenging task. To this aim, micron-sized particles exhibiting comparable to that nanoparticles were prepared in study via hydrothermal treatment hydrous particles. First, amorphous hydrolysis titanium alkoxide followed by partial dissolution the particle s...

Osteoporosis is a major public health problem. Exogenous estrogen or Hormone Replacement Therapy (HRT) the potential therapy for osteoporosis. Still, patient rarely chooses this treatment because of risk breast and endometrial cancer. Phytoestrogens estrogen-like compounds, particularly isoflavones, are potentially safe alternative to HRT. Jicama (Pachyrhizus erosus) plant that contains many ph...

Cereal Chem. 83(2):121–126 In dry-grind processing to produce ethanol from corn, unfermented solids are removed from ethanol by distillation and dried to produce distillers dried grains with solubles (DDGS), an animal food. Fouling of thin stillage evaporators has been identified as an important energy consumption issue in dry-grind facilities. Using an annular fouling apparatus, four batches o...

Abstract This study provides an efficient alternative by extracting bioactive compounds from Haematococcus pluvialis via matrix solid-phase dispersion (MSPD) its wet form, reducing one of the process steps with greatest economic impact, drying microalga. To obtain a suitable extract for nutraceutical purposes, solvents generally recognised as safe (GRAS) designation (ethanol, ethyl lactate, and...

Abstract Coffee by-products are a renewable, plentiful, cost-effective, and mostly untapped resource that could be used as biofuel feedstock. However, the energy efficiency yields determined by production technologies. Pretreatment procedure, hydrolysis methods, fermentation oil to biodiesel conversion techniques, binders employed, applying pressure temperature main factors improve from coffee ...
