Abstract Chemical gardens, which are self‐organizing, abiotic, inorganic precipitates in far‐from‐equilibrium systems, of interest for prebiotic chemistry/origin life research and, under certain reaction can be considered hydrothermal vent analogs. While the presence different additives to chemical including phosphate and amino acids, have been explored, reactivity organic molecules garden syst...

The properties of mineralogical and covalent inorganic polymers are brieffy described in the introductory part. Glass is an important polymer made up of rings and chains of silicate units which contain negatively charged oxygen atoms neutralized by positive metal ions. Glass and few other mineralogical types of inorganic polymers, like aluminum oxyde, could be fabricated into fibers and used as...

Introduction . Fibroblast growth factor type 23 (FGF-23) inhibits phosphate reabsorption and vitamin D hormone synthesis in the kidneys. There is a known relationship between FGF-23 levels serum phosphate, as well direct correlation hyperphosphatemia risk of cardiovascular events. Aim To evaluate associations bone mineral metabolism patients on renal replacement therapy (RRT) with hemo- periton...

Many manufactured articles are made of composite materials often bonded by a phenolic resin. Through D-optimal design, we optimized method to characterize resins after the extraction process GC-MS analysis. The study was conducted on three different and four with same inorganic composition analyzed binders. Moreover, cardanol that differ in their production systems were see if there differences...

In order to improve the performance of soft plantation wood, an environmentally friendly wood modifier was developed. First, using urea and melamine as crosslinking agents, glucose-urea-melamine resin (MUG) prepared with glucose under catalysis inorganic acid metal ions. Then MUG, sodium silicate, distilled water were mixed stirred at 40 °C prepare MUG resin/sodium silicate compound (G20S10, G1...

Beta-binders is a comparatively new modeling formalism introduced for systems biology. To execute Beta-binders models, suitable simulators are required which translate the operational semantics of Beta-binders into a sound and efficient execution. Efficiency can be reached by parallel and distributed simulation and by a proper representation of models to ensure a fast manipulation. Both possibi...

The preparation and characterization of composite materials based on geopolymers obtained from fly ash and epoxy resins are reported for the first time. These materials have been prepared through a synthetic method based on the concurrent reticulation of the organic and inorganic components that allows the formation of hydrogen bonding between the phases, ensuring a very high compatibility betw...

Nature has created amazing materials during the process of evolution, inspiring scientists to studiously mimic them. Nacre is of particular interest, and it has been studied for more than half-century for its strong, stiff, and tough attributes resulting from the recognized "brick-and-mortar" (B&M) layered structure comprised of inorganic aragonite platelets and biomacromolecules. The past two ...

In this research, the main investigation on macro level and durability characteristics of medium high strength geopolymer concrete composites, where cement is completely replaced with cementitious material integration granulated ground blast furnace slag (GFS) metakaolin (MKL) along sodium hydroxide (8 M, 10 16 M 20 M) silicate solution were rummage-sale as energizing binders. Many researchers ...

Abstract: Efforts have been carried out in order to use microsilica to develop a forsterite bond rather than other types of binders in the basic refractory castables. According to the higher drying rate and sinterability of colloidal silica, it has been proposed in the recent years. In the present work, effects of replacement of microsilica by colloidal silica evolution of forsterite bond have ...
