High Boron Content Enhances Bioactive Glass Biodegradation.

Derived Hench bioactive glass (BaG) containing boron (B) is explored in this work as it plays an important role in bone development and regeneration. B was also found to enhance BaG dissociation. However, it is only possible to incorporate a limited amount of B.

A Biodegradable Bioactive Glass-Based Hydration Sensor for Biomedical Applications.

Monitoring changes in edema-associated intracranial pressure that complicates trauma or surgery would lead to improved outcomes. Implantable pressure sensors have been explored, but these sensors require post-surgical removal, leading to the risk of injury to brain tissue. The use of biodegradable implantable sensors would help to eliminate this risk.

Original implementation of low-temperature SPS for bioactive glass used as a bone biomaterial.

Alkali borated bioactive glasses powders with compositions based on the SiO-NaO-CaO-PO-x BO system (0 < x < 20 wt%); have been consolidated at low temperature using Spark Plasma Sintering (SPS). Through SPS technique under 50 MPa, it was possible to achieve fully dense and completely amorphous borated glasses at temperatures as low as 420 °C. By increasing the sintering temperature up to 430 °C, the dense samples crystallized which is mostly achieved at higher temperatures.

Study of complex impedance spectroscopic properties of La Dy SrMnO perovskite oxides.

The dysprosium perovskite La Dy SrMnO ( = 0.00 [LSMO] and 0.03 [LDSMO]) compounds were prepared by the sol-gel reaction and characterized by the X-ray diffraction technique.

Analysis based on scaling relations of critical behaviour at PM-FM phase transition and universal curve of magnetocaloric effect in selected Ag-doped manganites.

The critical behaviour of PrSr Ag MnO (0 ≤ ≤ 0.2) samples around the paramagnetic-ferromagnetic phase transition is studied based on isothermal magnetization measurements. The assessments based on Banerjee's criteria reveal the samples undergoing a second-order magnetic phase transition.
