Research ArticleOpen accessIn the abstractThe Investigation of 1H NMR Spectra of 2,3-Dihydro-4-Pyridinones Derived from BisdemethoxycurcuminWisam A. Radhi, Bahjat A. SaeedProblem statement: The studied dihydropyridones were synthesized via microwave assisted reaction of bisdemethoxycurcumin and amines or amine acetates which is new approach in the synthesis of this important class of compounds and the deep study of their NMR spectra seems reasonable. Approach: 1H NMR spectra of dihydropyridones derived from curcumin were discussed and their structures were elucidated accordingly. Results: The … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,186 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBioactivity of Sumac (Rhus Coriaria) Extract as a Green Alternative for Plant Pathogen InhibitionMohammed H. Al-Mamoori, Meisam Zargar, Elena N. Pakina, Fatih DadaşoğluEnvironmental stress caused by pathogenic fungi leads to considerable losses in global crop productivity. Plant-derived extracts are eco-friendly and sustainable alternatives that can inhibit biotic stresses. Sumac (Rhus coriaria) is widely used in industrial and medicinal applications due to its extract rich in secondary metabolites, similar to those found in chemical pesticides and pharmaceuticals. This study aimed to characterize the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 25 Nov 2025 · 2,209 accessesView PDF Cite

Review ArticleOpen accessAll words, across the recordNanoboticsRelly Victoria Virgil PetrescuNanobotics (or Nanorobotics) is a field of emerging technology that deals with the creation of robots whose components are typically the size of a molecule or nanometer (10-9 meters). More specifically, nanorobotics refers to nanotechnology, an engineering discipline that designs and builds nanorobots that have movement, processing and transmission characteristics, program execution, etc. Nanomachines are largely in the research and … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 19 Jul 2020 · 7,783 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordFormation Mechanism and Characterization of PANI Nanoparticles by Hybrid Chemical and Gamma Irradiation TechniqueShawkat Salameh GasaymehHere we present additional data regarding specific doping process in nanoparticle samples of PANI. In such technique, the ionizing γ-irradiation and (dodecylbenzenesulfonic acid), DBSA were being used as dopants and as accelerators to the oxidizing agent to polymerize aniline monomer into conductive PANI Emeraldine Salt (ES), in which PANI was produced from its monomer by this noble methodology by a … …American Journal of Applied Sciences, Vol. 15, Issue 12 · 13 Feb 2019 · 8,381 accessesView PDF Cite
