Large Electrocaloric Responsivity and Energy Storage Response in the Lead-Free Ba(GeTi)O Ceramics.

Ferroelectric property that induces electrocaloric effect was investigated in Ba(GeTi)O ceramics, known as BTGx. X-ray diffraction analysis shows pure perovskite phases in tetragonal symmetry compatible with the 4 (No. 99) space group.

Dental Care in the Arab Countries During the COVID-19 Pandemic: An Infodemiological Study.

Background: Twitter is a powerful platform which could be used to reflect on the demand and supply of dental services during a pandemic. The aim of this study was to examine the nature and dissemination of COVID-19 information related to dentistry on Twitter platform Arabic database during the COVID-19 pandemic.

Methodology: One hundred and fifty independent searches with a combination of keywords for both COVID-19 and dentistry from a preselected Arabic keyword were carried out for the period from the 2nd of March (first confirmed cases of COVID-19) to the 6th of July 2020.

Pandemic preparedness of dentists against coronavirus disease: A Saudi Arabian experience.

Background: Dental offices are among the highest risk for transmission of the COVID-19, having the potential to transmit the virus via routine dental procedures. This cross-sectional study assessed the preparedness and perception of infection control measures against the COVID-19 pandemic by dentists in Saudi Arabia.

Materials And Methods: This online survey addressed the impact and perception of the COVID-19 pandemic on dental practice in Saudi Arabia.

Structural, Dielectric, and Magnetic Properties of Multiferroic ( 1 - x ) LaCaMnO-( x ) BaTiSnO Laminated Composites.

High-performance lead-free multiferroic composites are desired to replace the lead-based ceramics in multifunctional device applications. Laminated compounds were prepared from ferroelectric and ferromagnetic materials. In this work, we present the laminated ceramics compound by considering the ferromagnetic LaCaMnO (LCMO) and the ferroelectric BaTiSnO (BTSO) in two different proportions.
