E-Government services have become integral to modern governance, offering citizens convenient access to various public services online. However, the success of these services depends significantly on how users perceive and accept them. This paper explores the elements influencing users' views and acceptance of e-government services. Through an extensive review of literature and case studies, this study identifies key factors such as usability, security, trust, digital literacy, cultural factors, and government responsiveness. Understanding these elements is crucial for policymakers and service providers to design, implement, and enhance e-government services effectively. By addressing these factors, governments can improve user satisfaction, promote digital inclusion, and achieve broader societal benefits.

The imaging of thick frozen biological samples at nanometer resolution remains a significant challenge in the field of electron microscopy. Conventional techniques often suffer from limitations such as radiation damage and poor contrast in these samples. In recent years, there has been a growing interest in the development of novel instruments capable of overcoming these challenges. This article discusses the advancements towards the construction of a novel MeV-STEM (Mega-electron volt Scanning Transmission Electron Microscopy) system for imaging thick frozen biological samples with nanometer resolution. By leveraging the unique properties of high-energy electrons, such as reduced radiation damage and increased penetration depth, this system holds great promise for revolutionizing our understanding of biological structures at the nanoscale.

Additive Manufacturing (AM) techniques, such as Laser Powder Bed Fusion (LPBF), offer unique advantages in producing complex geometries with intricate internal structures. However, LPBF often yields parts with inherent porosity, which can compromise mechanical properties. To enhance the performance of such parts, post-processing techniques like resin infiltration have been explored. This article investigates the effects of epoxy resin infiltration on the structural integrity and mechanical properties of porous metal parts fabricated through LPBF. Through a comprehensive review of existing literature and experimental findings, this article sheds light on the optimization strategies and challenges associated with resin infiltration, ultimately aiming to contribute to the advancement of AM technologies.
