A promising material for bone repair: PMMA bone cement modified by dopamine-coated strontium-doped calcium polyphosphate particles [PDF]
Royal Society Open Science, 2019 Polymethyl methacrylate (PMMA) bone cement has been widely used in clinics as bone repair materials for its excellent mechanical properties and good injection properties. However, it also has defects such as poor biological performance, high temperature,

The physics of cement cohesion [PDF]
Sci. Adv. 7, eabg5882 (2021), 2021 Cement is one of the most produced materials in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, to which it provides a cohesive strength that rapidly increases during setting. Understanding how such cohesion emerges has been a major obstacle to advances in cement science and technology.

Well Cement Degradation and Wellbore Integrity in Geological CO2 Storages: A Literature Review [PDF]
Petroleum & Petrochemical Engineering 5 (2021), 2023 Carbon capture and storage (CCS) has emerged as the most effective method to curb the CO2 concentration in the atmosphere. It can store up to 5 billion tons of CO2 per year. To guarantee a safe and economical geological storage, the well cement degradation and wellbore integrity need to be studied thoroughly.

Modelling and simulation of acrylic bone cement injection and curing within the framework of vertebroplasty [PDF]
, 2013 The minimal invasive procedure of vertebroplasty is a surgical technique to treat compression fractures of vertebral bodies. During the treatment, liquid bone cement gets injected into the affected vertebral body and therein cures to a solid. In order to investigate the treatment and the impact of injected bone cement, an integrated modelling and ...

Osteoblasts infill irregular pores under curvature and porosity controls: A hypothesis-testing analysis of cell behaviours [PDF]
Biomech Model Mechanobiol (2018) 17:1357-1371, 2017 The geometric control of bone tissue growth plays a significant role in bone remodelling, age-related bone loss, and tissue engineering. However, how exactly geometry influences the behaviour of bone-forming cells remains elusive. Geometry modulates cell populations collectively through the evolving space available to the cells, but it may also ...
