A Review of Herbal Photoprotective Agents: From Traditional Knowledge to Modern Sunscreen Formulations
Abstract: Continuous exposure of skin to UV rays leads to tanning, premature aging, sunburn, pigmentation, and skin cancer. Sunscreens are widely used to protect the skin from these harmful stimuli. However, sunscreen components may interfere with other health concerns like irritation, itching, allergic reactions, and distinct environmental damage. This major concern initiated the introduction of herbal photoprotective agents, which are eco-friendly, safer for use, and rich in antioxidants (preventing free radicals). …

Gold Nanoparticle Size, Biodistribution, and Toxicity: Insights from DualEnergy CT
Abstract: Dual-energy and spectral computed tomography (CT) have emerged as powerful platforms for noninvasive, quantitative mapping of nanoparticle biodistribution in vivo. By exploiting the energy-dependent attenuation profiles of high-atomic-number (high-Z) materials, these systems enable material decomposition and element-specific imaging, thereby distinguishing nanoparticle signals from those of soft tissues and conventional iodinated contrast agents. Photon-counting spectral CT further enhances this capability by binning individual photons into multiple energy channels, improving spatial resolution, …

Digital Twin Assisted Intelligent Prediction of Polymer Composite Degradation Under Environmental Exposure
Abstract: Polymer matrix composites (PMCs) deployed in aerospace, marine, automotive, and renewable-energy structures are continuously subjected to coupled environmental stressors — ultraviolet (UV) radiation, moisture ingress, thermal cycling, and mechanical loading — that progressively degrade their mechanical performance. Conventional accelerated ageing tests and empirical lifetime models are time-consuming, destructive, and poorly suited to in-service, asset-specific degradation forecasting. This paper proposes a Digital Twin (DT) assisted intelligent prediction framework that fuses a …
