Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Enhancement of Adhesion between Resin Coating Materials and Resin Cements

Dental Materials Journal, 2007
Resin coating technique is a unique method that improves the dentin bond strength of resin cements in indirect restorations. However, the weak link of a specimen bonded using the resin coating technique was reported to be the bonded interface between the resin coating material and resin cement.

Impact of resin cement viscosity on bond strength to different zirconia ceramics after aging condition

Brazilian Dental Science
Objective: The current study examined how varying resin cement viscosities (high and low) impact the microshear bond strength (μSBS) of two distinct zirconia ceramics – 3Y-TZP and 4Y-PSZ– following an aging process. Material and Methods: Square zirconia

Feasibility of ossicular chain reconstruction with resin cement

Brazilian Journal of Otorhinolaryngology, 2017
Disjunction of ossicular chain is a common finding in middle ear chronic disease. In addition to ossicular interposition, various materials have been used for reconstruction, such as ceramic prostheses, polyethylene, and titanium.Because of the high cost of the available options, the authors propose to reconstruct the ossicular chain with resin cement,

Influence of activation modes on diametral tensile strength of dual-curing resin cements Influência dos métodos de ativação na resistência à tração diametral de cimentos resinosos duais

Brazilian Oral Research, 2005
In metallic restorations, the polymerization of dual-curing resin cements depends exclusively on chemical activation. The effect of the lack of photoactivation on the strength of these cements has been rarely studied.

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

Structural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...
