Its environment-friendly character is one more reason behind this focus. Nitrogen also has immense effect on activated carbon structures’ pollutants adsorption capability; therefore, it is an area of interest. Reports concerning the reaction pathway of C-N (carbon-nitrogen) bond creation on AC surface are limited. Determining such mechanisms is challenging but critical to understand bond characteristics after carbonization. Moreover, it is vital to ascertain real-time kinetics concerning adsorption phenomena in liquid phase. Such a latest trend indicates that regulated nitrogen uses for carbonaceous substances having a biomass-based origin can provide the desired morphological characteristics produced through interconnections, production of enclosed h...

A stable template-monomer complex generates MIPs with the highest affinity and selectivity for the template. In this investigation, degradation of Poly(ethylene terephthalate) PET afforded the (E)-4-(2-cyano-3-(dimethylamino) acryloyl) benzoic acid (4) (TAM) which used TAM as template which interacts with Methacrylic Acid (MAA) monomer, in the presence of CH3CN as progen. The TAM-MMA complex interactions are dependent on stable hydrogen bonding interaction between the carboxylic acid group of TAM and the hydroxyl group of MMA with minimal interference of porogen CH3CN. The DFT/B3LYP/6-31+G model chemistry was used to optimize their structures and frequency calculations. The binding energies between TAM with different monomers showed the most stable molar ratio of 1:4 which was confirmed through experimental analysis. Methods: The present work describes the synth...

Contemporary nations, in particular, have a strong desire to preserve their identity in terms of their individual heritage as well as their national contribution to overall mankind history and culture. Beside movable pieces of art like paintings, sculptures and other artifacts, architectonic, and urbanistic substance should be intensively preserved. Historic houses, town districts, whole urbanistic arrangements, castles, and other military objects are of interest to conservators and restorers. All such historic architectonic objects are made of apparently durable materials like ceramic bricks, stone of different type (marble, sandstone, granite, limestone, and other), or also wood. Because of aging, these materials are subjected to a natural decay beside wars and natural disasters. Natural deterioration is nowadays intensively accelerated by the so-called civilization factors of increasing ai...
