The effect of diisocyanate chain extender (CE) on the mechanical, rheological, and relaxation properties, as well as on molecular weight and crystallizability, of starting poly(ethylene terephthalate) (PET) and its composites containing carbon nanomaterials (CNM) such as carbon nanotubes (CNTs) and commercial carbon (…
Schiff base modified chitosan (SC: salicylidenechitosan) has been synthesized by the condensation reaction of chitosan and salicylaldehyde. From this ligand, three Cu(II) mixed ligand complexes [Cu (SC) (SA)] (1), [Cu (SC) (ST)] (2) and [Cu (SC) (VA)] (3) (SA: salicyledeneaniline; ST: salicylidenethiourea; VA: o-vanil…
A novel concept where the inorganic ultrathin nanoclay (organo-treated montmorillonite) film is incorporated into the organic light-emitting diodes (OLEDs) as a buffer layer is exploited to enhance the performance and the stability of the devices. To precisely control the thickness of organoclay films within ∼1 nm sca…
Interaction of potassium antimony(iii) tartrate hydrate K(2)(SbC(4)H(2)O(6))(2)·3H(2)O with the trilacunary Keggin derivatives [A-α-XW(9)O(34)](10-) (X = Si(IV), Ge(IV)) and [A-α-PW(9)O(34)](9-) in aqueous acidic medium (pH 4.8) resulted in three novel polyanions, [Sb(3)(A-α-XW(9)O(34))(2)](11-) (X = Si(IV) (1), Ge(IV…
Based on orthogonal design, black ceramic coating was obtained on AZ91D magnesium alloy with addition of carbon black pigment in electrolyte by micro-arc oxidation (MAO). The blackness, thickness, phase, morphology and composition of the coating were analyzed by visual detection, eddy current thickness meter, XRD, dig…
Continuous nanofibers of barium titanate (BaTiO3) with average diameter of 150–300 nm have been produced by means of mutual sol-gel and electrospinning routines with subsequent calcination step. The structural characterization of the obtained nanofibers has been performed by XRD and Raman spectroscopy. Their individua…
Nanometer-thick hexagonal boron nitride thin films were grown by thermal chemical vapor deposition on polycrystalline Ni, Co, and Cu substrates. A thicker and more regularly stacked film was grown on a Ni substrate, whereas a smaller film thickness and more turbostratic stacking or smaller domain size were observed on…
A 2nd generation polyamideamine (PAMAM) dendrimer bearing right-handed helices to its eight terminals was shown to accommodate eight left-handed helices via stereocomplex formation to generate molecular assemblies of disk structure with 13-14 nm diameter and 6 nm thickness.
When irradiated with nanosecond laser pulses, gold nanoparticles allow for manipulation or destruction of cells and proteins with high spatial and temporal precision. Gold nanorods are especially attractive, because they have an up-to-20-fold stronger absorption than a sphere of equal volume, which is shifted to the o…
The magnetotransmission, magnetoreflection, and magnetoresistance of the La 0.7 Ca 0.3 MnO 3 and La 0.9 Ag 0.1 MnO 3 epitaxial films have been investigated. It has been found that the films exhibit a significant magnetorefractive effect in the case of reflection and transmission of light in the fundamental absorption…
Bamboo mat boards (BMB) is a plywood-like wooden board produced from woven mats of bamboo that are soaked inadhesive resin and then pressed firmly together in a hot press.BMB is becoming popular as an eco-friendly material in housing applications such as panelling, ceilings, prefabricated shelters, roofs, doors and do…
ZnO thin films were deposited on microscope glass substrates by ultrasonic spray pyrolysis technique. The effects of annealing under various temperatures on the optical and structural properties of ZnO thin films were analyzed. The as-deposited and annealed ZnO thin films were investigated by UV/VIS spectrophotometer…
Quantum chemical calculations, based on DFT methods at B3LYP/6-31G** level of theory, were performed, by means of the GAUSSIAN 03 set of programs, on four recognized pyridazine compounds as corrosion inhibitors in acidic media. The objective of this work is to attempt to find relationships between their molecular and…
Multifunctional hybrid nanoparticles combine some of the unique physical and chemical characteristics of two or more classes of materials, such as polymers, liposomes, metals, quantum dots and mesoporous silica among others, to create a versatile and robust new class of nanoparticles. Here we discuss the most recent s…
Abstract: Plasma polymerized pyromucic aldehyde (PPPA) thin films have been deposited on to glass substrates by glow discharge technique. Scanning electron microscopy (SEM) graphs reveal that the surface morphology of PPPA thin films is uniform and flawless. FTIR analysis reveals that the chemical composition of PPPA…
