Nanosilica coating for bonding improvements to zirconia

International Journal of Nanomedicine, 2013
Resin bonding to zirconia cannot be established from standard methods that are currently utilized in conventional silica-based dental ceramics. The solution-gelatin (sol-gel) process is a well developed silica-coating technique used to modify the surface of nonsilica-based ceramics.

Bionic Lotus‐Leaf‐Inspired Superhydrophobic Nanostructure for High‐Performance Pharmaceutical Organic Adsorption

Heteroatom Chemistry, Volume 2026, Issue 1, 2026.
A bionic superhydrophobic method was conducted by combining hydrophobic modification of three‐dimensional (3D) and two‐dimensional (2D) materials with surface nanostructure regulation. Polydimethylsiloxane (PDMS)‐modified nanosilica (SiO2) was utilized with heteroatom‐functionalized aminosilane (KH550) as a key coupling agent to prepare a uniformly ...

Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.
