Background and Aim: Minimizing the polymerization shrinkage of composite resins is a critical goals in composite restorations. Many factors affect polymerization shrinkage. This study aimed to evaluate the effect of composite resin shade on polymerization shrinkage. Materials and Methods: In this in vitro study, 14 composite discs measuring 1.5×8 mm were fabricated. The samples were prepared u...
The current spraying of agrochemicals is unselective and ineffective, consuming a high amount fungicides, which endangers the environment human health. Cellulose-based nanocarriers (NCs) are promising tool in sustainable agriculture suitable vehicles for stimuli-responsive release to target cellulase-segregating fungi, cause severe plant diseases such as Apple Canker. Herein, cellulose was modi...
Background: Malaria is one of the most important parasitic diseases in the world caused by Plasmodium species. The malaria parasite digests hemoglobin in vacuole to amino acids and heme. Plasmodium has got several detoxification mechanisms to protect itself from toxic heme. The most important mechanism is heme polymerization. Identifying compounds that inhibit heme polymerization is an approach...
polybutadiene nanoparticles were synthesized via batch emulsion polymerization of butadiene in the presence of potassium persulfate, disproportionate rosinate potassium cation and t-dodecyl mercaptane as initiator, emulsifier and chain transfer agent, respectively. polymerization reaction was performed at different temperatures (60, 70 and 80 °c). conversion was measured at the various time int...
For the first time we present the synthesis of CeO(2)/Si(O)C core-shell particles prepared by the miniemulsion technique. The Si(O)C core was obtained by means of a polycarbosilane precursor (SMP10), which was subsequently functionalized with ceria and pyrolyzed to the ceramic. The size of these particles could easily be adjusted by varying the surfactants and the surfactant concentration, or b...
