Efficiency improvement in silicon and perovskite solar cells through nanofluid cooling using citrate and PVP stabilized silver nanoparticles.

This study investigates the enhancement of solar cell efficiency using nanofluid cooling systems, focusing on citrate-stabilized and PVP-stabilized silver nanoparticles. Traditional silicon-based and perovskite solar cells were examined to assess the impact of these nanofluids on efficiency improvement and thermal management. A Central Composite Design (CCD) was employed to vary nanoparticle concentration (0.

A multi-national survey-based evaluation of undergraduate/predoctoral endodontic education.

Aim: To evaluate the current status of endodontic education and assessment at an undergraduate/predoctoral level in dental schools worldwide.

Methodology: The current survey comprised a 50-item online questionnaire related to undergraduate endodontic education. The project leaders emailed the survey's details to faculty members responsible for endodontic teaching at one dental school in every country to seek their willingness to participate in the survey.

A randomized clinical trial comparing the effects of music and informative videos on patient anxiety during root canal treatment and retreatment.

Objectives: This randomized clinical trial compared the effectiveness of music and informative videos as distraction tools to reduce the anxiety of patients during root canal treatment and retreatment.

Method And Materials: A total of 90 patients were enrolled in the study. The patients were randomly allocated to three groups: Group 1 listened to music during the treatment (n = 30), Group 2 watched an informative preoperative video (n = 30), and a control group underwent treatment without a distraction method (n = 30).

Alcohol promotes liver fibrosis in high fat diet induced diabetic rats.

Objectives: Type 2 diabetes (T2DM) and alcoholism are considered to be lifestyle-associated independent risk factors in fatty liver diseases (FLD) mediated cirrhosis and hepatocellular carcinoma (HCC). A combined effect of both these conditions may exacerbate the pathological changes and a pre-clinical exploration of this is expected to provide a mechanical detail of the pathophysiology. The present study aims to understand the effect of alcohol on pre- diabetic and type 2 diabetic female Wistar rats.
