In the present study, the ballistic impact resistance of kevlar reinforced polymer composites and shape memoryalloy sheet reinforced kevlar epoxy polymer composites have been compared numerically and experimentally. The testspecimens have been fabricated by the hand layup method, and the ballistic impact test has been conducted accordingto NIJ Level IIIA. In the current research, a new method has been proposed to measure the ballistic impact resistanceof the material by using Image J software. From the test results, it has been observed that reinforcement of shape memoryalloy in kevlar epoxy polymer composites has increased the ballistic impact resistance by 89-145% for the damaged areacompared with plain kevlar reinforced epoxy polymer composite. Also, the damaged area observed in the numerical andthe experimental results is almost the same.

The technological developments of metal–organic framework (MOF) for selec-tive adsorption and sensing have been achieved in recent years. Herein, wereport two stilbene-based MOFs, denoted as Zn3(SDC)3(bpy) (1) and Zn(SDC)(bpy)2DMF (2). MOFs1and2were synthesized in pure form by controllingthe organic linker ratio and were used for the adsorptive removal of dye mole-cules. Despite their low adsorption capacities, the MOFs were more selectivetoward cationic dye (methylene blue) than anionic dye (methyl orange). Theunique fluorescent property of the MOFs was harnessed for the sensing ofharmful organic molecules. Interestingly, the fluorescence of10was quenchedby aromatic analytes containing amine and nitro functional groups. However,20only showed modest fluorescence quenching by nitrobenzene. The quench-ing efficiency of nitrobenzene had a low detection limit for10and20(14.28 and25.42μM, respectively). These MOFs can be used as adsorbents and highly sen-sitive chemical sensors.
