Curing Capacity of Band‐Bonding Resinous Adhesives Under 3D‐Printed Molar Bands
Orthodontics &Craniofacial Research, EarlyView.ABSTRACT Aim To evaluate the curing efficiency of three resin composite adhesives applied beneath 3D‐printed molar bands, by determining their degree of conversion (DC%) at different depths. Materials and Methods Fifteen 3D‐printed metallic band specimens were divided into three groups and bonded with Band Lock Blue (BLB), Optiband Ultra Blue (OBU), or

Study on the Permeability of Modified Bentonite Slurry in Landfill
Advances in Materials Science and Engineering, 2020 The impermeability of cutoff wall is one of the most important factors affecting the life of landfill. Hence, we used sodium carboxymethyl cellulose to modify bentonite and developed a modified bentonite-cement-fly ash antiseepage slurry with a low ...

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review
Safety Science and Technology, Volume 1, Issue 4, December 2026.This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Erosion Process of Polycarboxylate Cements in Organic Acids
Dental Materials Journal, 1983 The amounts of Zn and Mg eluted from the zinc polycarboxylate cement into acetic, lactic and citric acids increased with an increase in the formation constant of the acid-Zn or -Mg complexes. The erosion process consisted of two processes, namely, dissolution of the unreacted cement powder and decomposition of the matrix.
