(1 − x)Sr0.7Bi0.2TiO3-xBi(Mg0.5Ce0.5)O3 (x = 0.02, 0.04, 0.06, and 0.1) ceramics were prepared through the solid-state reaction method. Structural, microstructural, dielectric, and energy storage characteristics were thoroughly examined. A dense microstructure with a single perovskite phase was obtained for x ≤ 0.06. A high energy storage density of ~ 1.86 J/cm3, recoverable energy density of ~ 1.67 J/cm3, and a high efficiency of ~ 90% at a breakdown electric field strength of 240 kV/cm were achieved for x = 0.06. Further, this composition also shows a ΔC/C25°C in the range of − 55 to 135 °C. The above characteristics indicate that this material is a suitable candidate for power-pulsed capacitor applications.

The objective of this study is to explore the contents, features, and maintenance issues of Bangladeshi public university library websites. To ensure representativeness, we selected twelve (12) public university libraries that have dedicated websites. For authenticity and reliability of data, a checklist of sixty-one (61) items divided into ten (10) categories was used, along with interview procedures. The findings of this research have been presented in both tabular and figurative forms. According to the research, the website trend, which began a few years ago, will become a driving force for library services, although there is still potential for development such as liquid layout, mobile-friendliness, Web-OPAC, online tutorials, etc. and may indicate some maintenance issues for the library's website. This research is useful for information scientists and academic librarians involved in the establishment and management of library websites, particularly in underdeveloped nations like Bangladesh, where resources are restricted and studies are sparse.

The purpose of the study is to explore the present status, contents, and features that are used for user communication of private university library websites (PULW) in Dhaka city, Bangladesh. To ensure representativeness, purposively select twenty-two (22) private university libraries that have dedicated websites. A checklist contained sixty one (61) items divided into ten (10) categories, and interview methods were followed for authenticity and reliability of data. The result of this study has been presented in tabular and figurative forms. The study found that the trend of websites began a few years ago, will become a driving force for library services, though it has plenty of room for improvement, such as liquid layout, mobile-friendliness, Web-OPAC, online tutorials, etc., and shows some issues for library website maintenance. This study is valuable for information scientists and academic librarians who are connected with library website development and maintenance, especially in developing countries like Bangladesh, whose resources are limited and studies are also scarce.
