-
(Amer Chemical Soc, 2020)Porphyrin cyclophane 1, consisting of two rigidly fixed but still movable cofacial porphyrins and exposing acetatemasked thiols in opposed directions of the macrocycle, is designed, synthesized, and characterized. The ...
-
(Elsevier, 2015)Sol-gel based silica nanoparticles of 100 nm were used to interact with copper ions from the dissolution of CuCl2 allowing the synthesis of paratacamite (Cu-2(OH)(3)Cl) nanocrystals of around 20 nm. The method produced ...
-
(Elsevier, 2020)Metal-oxide based hybrid composite materials have broad applications in optical and electrochemical applications. Hence, in this present work fabrication of multifunctional Gd2O3/CdO composite using the facile sol-gel ...
-
(John Wiley, 2017)Semi-conducting polyethylene (PE) nanocomposites with outstanding magnetic properties at room temperature were synthesized. These exceptional properties, for a diamagnetic and insulating matrix as PE, were obtained by ...
-
(Wiley-Blackwell, 2015)This work reports the synthesis of nanostructured ZrO2 by anodization of zirconium electrodes at potentials well below the range of 10–50 V used as a standard procedure. Zirconium was first anodized in a 1M (NH4)2SO4 ...
-
(MDPI AG, 2019)© 2019 by the author. Licensee MDPI, Basel, Switzerland.Giant vesicles with several-micrometer diameters were prepared by the self-assembly of an amphiphilic block copolymer in the presence of the Belousov–Zhabotinsky (BZ) ...
-
(Nature Publishing Group, 2019)Here we report the biological synthesis of CdS fluorescent nanoparticles (Quantum Dots, QDs) by polyextremophile halophilic bacteria isolated from Atacama Salt Flat (Chile), Uyuni Salt Flat (Bolivia) and the Dead Sea ...
-
(Elsevier, 2021)This work reports the synthesis of poly (monomethyl itaconate) grafted multi-layer graphene oxide (PMMI-g-GO) by atom transfer radical polymerization using activators regenerated by electron transfer (ARGET-ATRP). PMMIg-GO ...
-
(Elsevier Ltd, 2019)A series of amphiphilic polymers bearing aliphatic secondary amines and hydroxyl groups have been synthesized showing different hydrophilic/hydrophobic balance. The synthesis is performed through the Paal-Knorr modification ...
-
(Elsevier, 2014)To study the electronic influence of the organometallic moieties in thiosemicarbazones, two short libraries of cyrhetrenyl thiosemicarbazone and ferrocenyl thiosemicarbazone hybrids were synthesized and tested for their ...
-
(Elsevier, 2015)Poly(propylene-1-octene)/graphite nanosheet (PPC8/GNS) nanocomposites with different comonomer and graphite nanosheet (GNS) contents were synthesized by in situ polymerization using metallocene catalyst. There was a ...
-
(Elsevier, 2015)Cyrhetrenyl crown ether complexes [(eta(5)-C5H4CH=N-M)Re(CO)(3)] (where M = 4-benzo-15-crown-5 (3a), 4-benzo-18-crown-6 (3b), 2-methyl-15-crown-5 (3c), or 2-methyl-18-crown-6 (3d)) were synthesised from cyrhetrenylcarboxaldehyde ...
-
(2010)The synthesis, spectroscopic and structural characterization, linear and nonlinear optical properties, as well as the electrochemical behavior of a series of robust neutral binuclear M[Fc-C(O)CHdC(CH3)N-X-NdCH-(2-O,5-R-C6H3)] (M ...
-
(Elsevier, 2014)The UV irradiation of a hexane solution of the complex (n5-C5Me4(CH2)2NMe2)Re(CO)3 (1) afforded the chelated species (n5:n1-C5Me4(CH2)2NMe2)Re(CO)2 (2). The molecular structure of 2 has been determined by X-ray ...
-
(Geological Society of America, 2018-06)The Central Andes is a key global location to study the enigmatic relation between volcanism and plutonism because it has been the site of large ignimbrite-forming eruptions during the past several million years and currently ...
-
(IEEE-Inst Electrical Electronics Engineers, 2021)The increasing integration of renewable energy sources into current power systems has posed the challenge of adequately representing the statistical properties associated with their variable power generation. In this paper, ...
