Copper sulfide nanoparticles have been employed as artificial mimics for peroxidase-like activity. In the present study, copper sulfide nanoparticles with four different morphologies have been synthesized by thermal decomposition of cyclo-tri-μ-thioacetamide-tris(chlorocopper(I)) complex ([Cu3TAA3Cl3]) at 200 °C in different solvents such as diphenyl ether, ethylene glycol, 1-octadecene and also without any solvent. Hierarchical copper sulfide nanostructures are formed when the complex is decomposed in the absence of solvent, in diphenyl ether, and 1-octadecene while in the case of ethylene glycol, randomly agglomerated nanoparticles are formed. The precursor complex ([Cu3TAA3Cl3]) as well as copper sulfide nanoparticles were characterized using an array of techniques and after characterization, the peroxidase-like activity of copper sulfide nanoparticles was investigated.Morphologically different copper sulfide nanoparticles possess different exposed facets and due to this, the peroxidase-like activity was different among different morphologies.

In this work, a facile approach combining polymerization-induced phase separation and starch-templating is presented to synthesize hierarchically macro/mesoporous carbons. The obtained porous carbons have bimodal macropores with pore diameters of 10~60 μm and 3~5 μm and 3D interconnected mesopores with pore diameters of 5~40 nm. The large macropores and the small macropores are obtained by the thermal decomposition and the closely stacking of starch particles, respectively. The 3D interconnected mesopores are developed through polymerization-induced phase separation between ethylene glycol and phenolic resin via spinodal decomposition mechanism. These as-prepared hierarchically macro/mesoporous carbons may have great potential for applications as electrodes materials for batteries, fuel cells, and supercapacitors due to their facile synthesis, unique hierarchical porous structure, and large BET surface areas (~ 610 m2/g).

Molecularly Imprinted Polymer (MIP) has been synthesized with carbaryl used as a template and forms complex bonds with Methacrylic Acid (MAA)through hydrogen bonds, followed by a cross-linking process using Ethylene Glycol Dimethacrylate (EGDMA) cross-linkers. The polymerization process begins with the thermal decomposition of Benzoyl Peroxide (BPO) as an initiator. Non-Imprinted Polymer (NIP) as a control polymer has also been synthesized using a similar procedure without using carbaryl templates. In this study, two variations of carbaryl are used, which are not milled carbamates, and carbaryl has been milled using High Energy Milling (HEM). The FTIR study was carried out to investigate the presence of carbaryl in polymers, MIP, and NIP. The spectrum shows that the concentration of carbaryl compound decreases after the extraction process. This result was also confirmed by the increase in the value of the percentage of transmittance in the MIP, especially the nano carbaryl MIP. This result is supported by the X-RD results, which showed a decrease in the size of the crystals in the carbaryl MIP from 10.07 Å while the nano carbaryl MIP was 9.16 Å.
