The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper
(USA :Taylor & Francis INC, 2020)
This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use ...
Improvement of d–d interactions in density functional tight binding for transition metal ions with a ligand field model: assessment of a DFTB3+ U model on nickel coordination compounds
(Royal Society of Chemistry (RSC), 2020)
To improve the description of interactions among the localized d, f electrons in transition metals, we have introduced a ligand-field motivated contribution into the Density Functional Tight Binding (DFTB) model. Referred ...
Fatigue fracture analysis of helicopter landing gear cross tube
(Elsevier, 2021)
This paper presents the failure analysis results of the helicopter skid landing gear. The helicopter skid landing gear fractured while the helicopter was on the ground at the airport. The aft cross tube of the landing gear ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier, 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticles (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Influence of C–H/X (X = S, Cl, N, Pt/Pd) Interactions on the Molecular and Crystal Structures of Pt(II) and Pd(II) Complexes with Thiomorpholine-4-carbonitrile: Crystallographic, Thermal, and DFT Study
(American Chemical Society (ACS), 2020)
Pt(II) and Pd(II) complexes (1 and 2, respectively) with thiomorpholine-4-carbonitrile (TM-CN), an N-substituted thiomorpholine derivative, were synthesized from tetrachlorido precursors in water. Structural analysis has ...
Insight into the Origin of Pyrocatechol Inhibition on Oscillating Bray-Liebhafsky Reaction: Combined Experimental and Theoretical Study
(Chemical Society of Japan, 2020)
The pyrocatechol inhibitory effect on the oscillatory Bray-Liebhafsky (BL) reaction is reported. Obtained results are compared with those available in the literature (R. Cervellati et al, Helvetica Chimica Acta 2001) for ...
Visible light promoted photoredox C(sp3)-H bond functionalization of tetrahydroisoquinolines in flow
(Royal Society of Chemistry, 2021)
A merger of organocatalysis and visible light photoredox catalysis performed in flow allowed access to a wide range of functionalizedN-aryl-substituted tetrahydroisoquinolines (THIQs) in a formal C-H oxidation/Mannich ...
Natural Pigment from Madder Plant as an Eco-Friendly Cathode Material for Aqueous Li and Na-Ion Batteries
(IOP Publishing, 2021)
Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides an
examination of a potential replacement for commercial cathode material using a naturally occurring ...
Functional ibuprofen-loaded cationic nanoemulsion: Development and optimization for dry eye disease treatment
(Elsevier, 2020)
Abstract: Inflammation plays a key role in dry eye disease (DED)affecting millions of people worldwide. Non-steroidal anti-inflammatorydrugs (NSAIDs) can be used topically to act on the inflammatory componentof DED, but ...
Influence of selective acid-etching on functionality of halloysite-chitosan nanocontainers for sustained drug release
(Elsevier, 2021)
The functionality of halloysite (Hal) nanotubes as drug carriers can be improved by lumen enlargement and polymer modification. This study investigates the influence of selective acid etching on Hal functionalization with ...
