Effect of Bi2O3 Content and Sintering Temperature on the Frequency-Dependent Magnetic Properties of Nanosized Barium Hexaferrite
Abstract: The magnetic properties of commercially available nanosized barium hexaferrite (BaFe12O19) are studied. The particles were characterized using X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and high-frequency magnetic measurements. The frequency-dependent magnetic properties viz. complex permeability and loss tangent were analyzed within the 10 MHz to 1 GHz range. Variations in complex magnetic permeability and loss tangent were discussed under varying sintering parameters such as temperature and sintering aid content. The …

Nano‑Enabled CT for Cancer Imaging: From Molecular Targeting to Image‑Guided Therapy
Abstract: Nano‑enabled computed tomography (CT) exploits high‑atomic‑number (high‑Z) nanomaterials engineered with targeting ligands and therapeutic payloads to enhance contrast, enable molecular imaging, and support image‑guided interventions in oncology. Tumor‑specific nanoprobes such as RGD‑modified gold nanorods, polymer‑coated bismuth nanoparticles, and peptide, antibody, or aptamer‑functionalized platforms can intensify tumor conspicuity, allow early lesion detection and staging, and provide real‑time treatment monitoring. Integration of CT visibility with photothermal, photodynamic, chemo‑, radio‑, and immunotherapeutic functions …

Recent Trends in Ocular Drug Delivery: Challenges and Approaches
Abstract: Drug topically regulation can be accessed most easily in the eye. When given topically as eye drops, medication ocular bioavailability is quite low. Drug entry into specific ocular locations is complicated by the complex anatomy and physiology of the human eye. Research has long been interested in the topical administration of successful treatments. To provide a suitable ocular penetration and extend the duration of drug residence is their challenging task. …

Physiographic, Climatic, and Hydrogeological Determinants of Urban Flooding in Bhopal: A Spatial Assessment
Abstract: Bhopal, capital city of Madhya Pradesh, is uniquely shaped by hilly terrain, lake systems, and complex hydrogeological characteristics, which historically supported efficient natural drainage. However, rapid urbanization, encroachment, and alterations in land use have increasingly disrupted these natural systems, amplifying the city’s susceptibility to urban flooding. The city’s physiography, defined by five major hills, undulating slopes, and a network of natural drainage channels, directs runoff toward low-lying zones that frequently …

Design and Validation of an Artificial Intelligence-Driven Digital Twin for Real-Time Monitoring and Control in Polymer Composite Manufacturing
Abstract: Polymer Matrix Composites (PMCs) have become indispensable in high-performance sectors such as aerospace and automotive engineering, offering exceptional strength-to-weight ratios that outperform traditional metals in many demanding applications. However, the reliability of manufacturing PMCs via Vacuum-Assisted Resin Transfer Molding (VARTM) is frequently undermined by stochastic process variabilities. Unpredictable fluctuations in thermal history, preform permeability, resin rheology, and ambient conditions often lead to some defects; namely voids, dry spots, and incomplete …
