Over a decade, a significant advancement in the development of nanohybrids has been observed to address the challenges related to sustainable energy systems. In this regard, the review critically examines the emerging functions of carbon-based quantum dots (CQDs) and graphene-based quantum dots (GQDs) and their nanohybrids in photoelectrochemical (PEC) applications, focusing on their different physicochemical properties. Nanohybrids constituting CQDs and GQDs can be breakthrough materials, which have evolved as emerging materials recently in PEC research owing to the mirrored properties of conventional quantum dots. Moreover, the surface chemistry and the electronic structure governed by the size of the quantum dots (QDs) facilitate wide tailoring opportunities in the nanohybrids, serving multifunctionality. A perspective on material design and probability is put forward. Understanding their individual contributions prior to exploring their impact on the PEC system is highly essential. The successful creation and functionality of CQDs/GQDs nanohybrids depend on the composite/nanohybrid processing of CQDs/GQDs while maintaining their intrinsic properties in the nanohybrid forms. The application of CQDs/GQDs in PEC applications remains largely experimental and lab-scale at this stage. Establishing a detailed structure-performance-stability relationship is crucial while conducting permutation-combination of different PEC experiments, integrating physicochemical characterization's, and understanding the QDs properties.

The cloud computing environment offers significant flexibility and access to computing re- sources at a reduced cost. This technology is rapidly transforming the landscape of e-services across various fields. In this paper, we examine cloud computing services and applications, high- lighting examples of services offered by leading Cloud Service Providers (CSPs) such as Google, Microsoft, Amazon, HP, and Salesforce. We also showcase innovative cloud applications in areas like e-learning, Enterprise Resource Planning (ERP), and e-governance. This study aims to help individuals and organizations recognize how cloud computing can deliver customized, reliable, and cost-effective solutions across a diverse range of applications
Helium cold atmospheric pressure plasma reduces erastin induced inflammation and ferroptosis in human gingival fibroblasts

Scientific Reports
Oral soft tissue damage can lead to hard tissue damage in the oral cavity, such as periodontal lesions, periapical disorders, cysts, and oral tumors. Cold plasma is known to alleviate inflammation and oxidative stress and promote tissue regeneration, yet the effects of helium plasma on human gingival cells remain poorly understood. In this study, we examined whether helium (He) cold atmospheric pressure plasma (CAP) can induce anti-inflammatory and anti-ferroptotic effects in oral soft tissues by ionizing He gas. Erastin treatment followed by He CAP exposure in human gingival fibroblast-1 (HGF-1) cells reduced the mRNA expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-1β (IL-1β), tumor necrosis factor-α (TNFα), and interleukin-6 (IL-6), which are linked to inflammatory responses. Additionally, He CAP exposure decreased nuclear receptor coactivator 4 (NCOA4) expression and increased glutathione peroxidase 4 (GPX4) expression. Furthermore, mitochondrial membrane potential was restored by increased voltage-dependent anion channel 1 (VDAC1) expression, and reactive oxygen species (ROS) levels in mitochondria and cytoplasm were reduced. These results suggest that He CAP exposure may be associated with modulation of mitochondrial ROS production and reduction of inflammation and ferroptosis, but whether mitochondrial repair contributes to these effects requires further investigation.
