Introducing Acid–Base Titration on Paper-Based Analytical Devices in a High-School Chemistry Laboratory for the Determination of Acetylsalicylic Acid

Abstract In this study, paper-based analytical devices (PADs) were used to introduce a simple, rapid, portable, and low-cost acid–base titration method in high school chemistry laboratories. Students performed conventional and paper-based titrations to determine the amount of ace...

Impact of anthropogenic activities on the microplastic pollution status of an urbanized wetland

Due to their environmental ubiquity, persistence, and potential effects on living organisms, microplastic pollution has become a global concern. Urban wetlands, catchment basins within cities, are one of the final sinks of these pollutants. We studied the occurrence, abundance, d...

Direct-Write Laser-InducedGraphene Microstrip PatchAntennas on Medium-Density Fiberboard

Abstract Laser-induced graphene (LIG) has been used in flexible and wearable antennas fabricated on polymeric substrates and paper; however, these materials are not ideal for seamless integration into rigid indoor structures. Antennas integrated into such structures would represe...
