Under certain conditions, femtosecond lasers can be used to introduce self-organized nanogratings in the bulk of fused silica. Here, we report that the nanogratings orientation influences the induced stress distribution around laser affected zones. ...
Biomineralization processes leading to complex solid structures of inorganic material in biological systems are constantly gaining attention in biotechnology and biomedical research. An outstanding example for biomineral morphogenesis is the formation of h ...
Despite the widespread use of amorphous aluminosilicates (ASA) in various industrial catalysts, the nature of the interface between silica and alumina and the atomic structure of the catalytically active sites are still subject to debate. Here, by the use ...
Over the last decade, femtosecond lasers have been used extensively for the fabrication of optical elements via direct writing and in combination with chemical etching. These processes have been an enabling technology for manufacturing a variety of devices ...
Grafting reactive molecular complexes on dehydroxylated amorphous silica is a strategy to develop ``single-site'' heterogeneous catalysts. In general, only the reactivity of isolated silanols is invoked for silica dehydroxylated at 700 degrees C ([SiO2-700 ...
Electrostatic spray ionization (ESTASI) mass spectrometry imaging (MSI), recently developed to profile spatial distribution of chemical and biochemical molecules on an insulating surface under ambient conditions, has been applied to identify and quantify c ...
Silica-like nanoparticles are produced from four different organosilicon monomers HMDSO, TMDSO, TEOS and TMOS in a continuous non-equilibrium plasma reactor. The nanoparticle synthesis is studied as a function of the process pressure, plasma power, gas vel ...
One of the most serious causes of degradation of concrete is the alkalisilica reaction. Amorphous silicates present in certain aggregates react with the alkaline pore solution of the concrete to form a gel, which absorbs water and swells, leading to the ex ...
Supplementary cementitious materials (SCMs) are widely used to partially replace portland clinker in blended cements. Reducing clinker contents further without compromising the development of early strength necessitates a better assessment and enhancement ...
The shear thickening behavior of concentrated suspensions can be exploited to dissipate energy during impact or shear loading. To preserve the consistency of the thickening behavior in practical applications, particle concentration, and dispersion should b ...
