Effects of nanosilica on compressive strength and durability properties of concrete with different water to binder ratios [PDF]
, 2016 The effects of the addition of different nanosilica dosages (0.5%, 1%, and 1.5% with respect to cement) on compressive strength and durability properties of concrete with water/binder ratios 0.65, 0.55, and 0.5 were investigated.

Experimental Study on Nano Silica Concrete
International Journal for Research in Applied Science and Engineering Technology, 2023 Abstract: Concrete is the most common material for construction. The total production depends upon the cement content only. Due to the usage, large amount of cement produces increasing the CO2emissions, to reduce the cement percentage in concrete mixes the nanosilica (nSiO2) is used as the replacement of the cement. The application of nanotechnology to

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Advanced Functional Materials, EarlyView.Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by
