Synthesis, Characterization, Catalytic Activity, and DFT Calculations of Zn(II) Hydrazone Complexes
(MDPI, 2020)
Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and single ...
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 ...
Numerical simulation of fluid-structure interaction between fishing wobbler and water
(Niš, Serbia : University of Niš, 2020)
This paper deals with modeling, discretization, and numerical analysis of the two-way fluid-structure interaction between a fishing wobbler and a water stream. The structural domain is an assembly of several bodies that ...
Artificial intelligence-based optimization of a bimorph-segmented tapered piezoelectric mems energy harvester for multimode operation
(MDPI, 2021)
This paper presents a study on the design and multiobjective optimization of a bimorph-segmented linearly tapered piezoelectric harvester for low-frequency and multimode vibration energy harvesting. The procedure starts ...
Monolithically Integrated Diffused Silicon Two-Zone Heaters for Silicon-Pyrex Glass Microreactors for Production of Nanoparticles: Heat Exchange Aspects.
(MDPI, 2020)
We present the design, simulation, fabrication and characterization of monolithically
integrated high resistivity p-type boron-di used silicon two-zone heaters in a model high temperature
microreactor intended for ...
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 ...
Hepatoprotective effect of mixture of dipropyl polysulfides in concanavalin a-induced hepatitis
(MDPI, 2021)
The main biologically active components of plants belonging to the genus Allium, responsible for their biological activities, including anti-inflammatory, antioxidant and immunomodulatory, are organosulfur compounds. The ...
Oscillatory Briggs-Rauscher Reaction as “Fingerprint” for Bentonite Identification: The Fine-Tuning of Oscillatory Dynamics with Addition of Clay
(Wiley, 2020)
The oscillatory Briggs‐Rauscher (BR) reaction was applied on solid insoluble materials i. e. bentonite clays. Under the same BR experimental conditions, the addition of identical masses of bentonite of different origin ...
Solvent effects on structural changes in self-healing epoxy composites
(Elsevier, 2020)
Nowadays, there is a very high importance of composite research and variety of their applications in the modern world. In that sense, we researched hollow glass capillaries filled with dissolved Grubbs catalyst (GC) and ...
Floating-Gate MOS Transistor with Dynamic Biasing as a Radiation Sensor
(MDPI, 2020)
This paper describes the possibility of using an Electrically Programmable Analog Device (EPAD) as a gamma radiation sensor. Zero-biased EPAD has the lowest fading and the highest sensitivity in the 300 Gy dose range. ...
