The regenerated cellulose (RC)biocomposite films were prepared using casting method where oil palm empty fruit bunch (OPEFB) and microcrystalline cellulose (MCC) were dissolved in N-dimethylacetamide/lithium chloride (DMAc/LiCl)solution. The increasing of OPEFB contents up to 2 wt% increased the tensile strength and m…
Four organic-charge transfer (CT) complexes ( <bold>Ct1–Ct4</bold> ) have been reported. <bold>Ct1</bold> discerns <italic>p</italic> -xylene in the presence of a xylene mixture.
Two new sandwich-type lanthanide complexes with the general formula [(Pc)2Ln3(L)(OAc)(OCH3)2] (Ln(3+) = Dy(3+) () and Er(3+) ()) were successfully synthesized and structurally characterized based on closed-macrocyclic Schiff base and phthalocyanine molecules. The magnetic properties and structure-property relationship…
A fish-basket-shaped [Co24] cluster, [Co24(μ3-O)4(ampc)4(μ3-OH)4(μ2-OH)4(NO3)5(HCO2)22(H2O)10]·[(HCO2)·2(CH3OH)·x(H2O)], was woven by bridging oxygen atoms from O(2-), OH(-), NO3(-) and HCO2(-) groups, and stabilized terminally by a semi-rigid organic ligand 4',4'-[(dimethylamino)dimethylene]-bis[(1,1'-biphenyl)-2-car…
extracts could serve as source of antidiabetic agents which may act through the inhibition of carbohydrate hydrolyzing enzymes, α-amylase and α-glucosidase.
The complex effect of platy and tubular nanofillers on the performance of a biodegradable multiphase polymer system is presented.
An attempt has been made to improve the corrosion behavior of WE43 magnesium alloy by laser surface melting (LSM) using a 10 kW continuous-wave CO <sub>2</sub> laser.
Ionomers, or single-ion conductors, serve as a model system to study ion transport in polymeric systems. Conductivity is a system property that depends on the net charge transport in the system. The mechanism through which ions are transported can dramatically change the contribution of an ion's self-motion (i.e. diff…
Graphene sheets can be considered as a promising a support material for the catalytic nanoparticles. Here, we present a new approach for the preparation of graphene with noble metals nanoparticle on its surface using supercritical propanol - 2 as a reducing agent for nanocomposites graphene oxide- Pd or Pt nanoparticl…
TEM image of the fracture structure of CNTs/CS/EP.
A UV transparent and stable fluoro-siloxane hybrid material was prepared for a deep UV-LED encapsulant. The hybrimer was fabricated by hydrosilylation reaction of vinyl-fluoro oligosiloxane resin.
Using first-principle calculations, we studied the interaction between Li and graphene by considering the two kinds of models, which are related to the configurations of Li adsorption and the concentration of Li on graphene.
A one atom-thick sheet of carbon exhibits outstanding elastic moduli and tensile strength in its pristine form but structural defects which are inevitable in graphene due to its production techniques can alter its structural properties.
Nanoplasmonics is a growing field of optical condensed matter science dedicated to optical phenomena at the nanoscale level in metal systems. Extensive research on noble metallic nanoparticles (NPs) has emerged within the last two decades due to their ability to keep the optical energy concentrated in the vicinity of…
Quantum transport studies are performed on doped (boron, nitrogen, oxygen, silicon, phosphorus, and sulfur) and functionalized (borane, amine, hydroxyl, thiol, silane, silene, phosphine, and phosphorane) armchair graphene nanoribbons by means of density functional theory.
Solution plasma process (SPP) was adopted to prepare alginate/silver nanoparticle (AL/AgNP) biocomposites. The biocomposites were synthesized in solutions of varying concentrations of AgNO 3 (1−5 mM) and alginate (0.1−0.3%, w/w) by discharging plasma for 7 min at 800 V with 30 kHz frequency using a pulsed unipolar pow…
Hybrid nanohelices were obtained from silicification of self-assemblies of gemini surfactants with tartrate counterions. The chiral arrangement of these non-chiral gemini surfactants was preserved in the silica matrix even after the counterion exchange for a non-chiral bromide, and was capable of inducing the chiral o…
The CoO <sub>x</sub> /SiO <sub>2</sub> spherical particles with hollow or mesoporous structure were successfully prepared by spray pyrolysis by using the NaCl and NaNO <sub>3</sub> as <italic>in situ</italic> formed templates for the first time.
We present a first principles study of low-spin (LS)/high-spin (HS) screening for 3d metal centers in the metal organic framework (MOF) DUT-8(Ni). Various density functional theory (DFT) codes have been used to evaluate numerical and DFT related errors. We compare highly accurate all-electron implementations with the…
Two thermally stable single-ion magnets containing a dysprosium ion with the ligand fod (1,1,1,2,2,3,3-heptafluoro-7,7-dimethyl-4,6-octadione) and bpy (2,2′-bipyridine) or phen (1,10-phenathroline) were synthesized, named 1Dy (Dyfod3bpy) and 2Dy (Dyfod3phen). They both have 6 oxygen atoms and 2 nitrogen atoms around t…
