As research in advanced materials expands, graphene derivatives with engineered surface chemistry are increasingly shaping next-generation technologies (Zhang et al., 2022; Grand View Research, 2024). Among these, tetraethylene pentamine-functionalized reduced graphene oxide (rGO-TEPA) stands out for its ability to To combine high electrical conductivity with abundant amine functional groups that enable strong chemical interactions. Recent studies confirm that functionalized graphene derivativ …

Fashion has always been an expression of identity, but now it has become a medium of interaction. Today, clothing not only reflects personal style - it senses, responds, and communicates. From temperature-regulating coats to light-reactive fabrics, technology is being woven into every fiber of modern design. At the forefront of this transformation stands Nanografi Conductive Inks, engineering conductive formulations that enable textiles to transmit signals, store data, and respond to their surro …

From Hollywood forgeries to high-tech prevention Remember Catch Me If You Can? Frank Abagnale’s legendary escapades showed how a typewriter, a checkbook, and quick charm once fooled entire banking systems. Back then, the world relied on paper, pigment, and trust - and sometimes, the pigment gave way first. Checks and legal documents were easy prey because: Paper stock lacked embedded fibers or security threads. Printing presses used widely available commercial inks. Colors and seals coul …

Introduction The convergence of digital and physical domains has transformed product authentication from a visual verification task into a complex field of material and information security. In an increasingly interconnected industrial ecosystem, the reliability of supply chains depends on the ability to guarantee the origin, integrity, and traceability of physical goods. Conventional protection methods -such as holograms, serial codes, and barcodes- offer limited resilience against replication …

Quantum dots (QDs) are nanoscale semiconductor crystals capable of emitting light at specific wavelengths when exposed to UV light or other energy sources. Their ability to fluoresce in specific, tunable colors determined by the size and composition of each particle makes them ideal for brand protection applications. Unlike conventional dyes, quantum dots are highly photostable, resistant to fading, and able to deliver distinct optical signatures. This allows them to be embedded into inks, label …
