Liquid-Solid Phase Transition Alloy as Reversible and Rapid Molding Bone Cement [PDF]
Bone cement has been demonstrated as an essential restorative material in the orthopedic surgery. However current materials often imply unavoidable drawbacks, such as tissue-cement reaction induced thermal injuries and troublesome revision procedure.

Cytocompatible, radiopaque, and antibacterial bismuth‐doped gel‐derived 58S bioactive glasses
Abstract Larry L. Hench's research group first introduced gel‐derived bioactive glasses (BGs) in 1991. These BGs offer a broader range of bioactivity than traditional melt‐derived BGs. Highly porous gel‐derived glasses are suitable for various applications, such as bone and soft tissue engineering.

ABSTRACT Objectives There are two technologies for restoring individual structurally defective teeth. A direct restoration is applied chairside in one appointment, while an indirect restoration needs to be lab‐produced before application. This umbrella review of previous English systematic reviews was conducted to determine if there was any difference ...

Optimal cement paste yield stress for the production of stable cement foams [PDF]
Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is expected to promote stability by damping intrinsic bubble kinetics. Here we show however that for given W/C ratio, fresh foam stability can be achieved instead by decreasing

An objective assessment of the ossicular chain with laser vibrometry would likely improve the result of ossiculoplasty. MIVIB provides an objective assessment of the ossicular chain to identify specific fixations and therefore assist the surgeon in improving surgical outcomes. ABSTRACT Background Conductive hearing loss requires the surgeon to evaluate

Molecular dynamics modeling of the effects of cementation on the acoustical properties of granular sedimentary rocks [PDF]
The incidence of cementation processes on the acoustical properties of sands is studied via molecular dynamics simulation techniques. In our simulations, we consider samples with different degrees of compaction and cementing materials with distinct elastic properties.
