    Effect of Cobalt Composition on Electrochemical Behavior of Platinum-Based Catalyst towards Hydrogen Evolution Reaction

    by Duc Thanh Nguyen, Hang Thi Thuy Nguyen, Hung Cam Ly and An Thi Xuan Duong*
    AFM 2022, Vol 2, Issue 2, 1-6, https://doi.org/10.35745/afm2022v02.02.0001 - Published on June 30, 2022

    Abstract

    The hydrogen production from water electrolysis is of interest as a renewable energy generation technology. However, the high price of noble platinum (Pt) catalysts for the hydrogen evolution reaction (HER) is a big challenge to use it. Herein, we fabricate cost-effective CoPt bimetallic alloys and explore the effect of Co composition on the electrochemical behavior of such alloys, which has been rarely reported. A series of Co1-xPtx (x = 0.25; 0.5; 0.75) alloys are prepared via a room-temperatu...

    Analogy among Center of Gravity, Center of Mass, and Centroid of Rigid body: Analysis of Formula for Their Respective Calculation as per Configuration of Body and Utilization in Composite Application

    by Saransh Tiwari, Sudhaker Dixit*, Ved Kumar and Ayushi Rastogi
    AFM 2022, Vol 2, Issue 2, 7-13, https://doi.org/10.35745/afm2022v02.02.0002 - Published on June 30, 2022

    Abstract

    The essential distinctions and similarities between the center of gravity, the center of mass, and the centroid of a rigid body in space are illustrated in this article. The use of an acceptable equation for a given configuration of the body situated at any location in a 3-D space is established and used in a composite application in the boiler lever safety valve....

    Photovoltaic Performance of CH3NH3PbI2Cl Perovskite Solar Cell

    by Yi-Tzu Tseng,, Yu-Ting Tseng and Chia-Ching Wu*
    AFM 2022, Vol 2, Issue 2, 14-20, https://doi.org/10.35745/afm2022v02.02.0003 - Published on June 30, 2022

    Abstract

    Perovskite solar cells have attracted extensive research attention recently as they are promising high-performance solar cells with long-time stability at a low cost. In this study, we demonstrated a one-step solution approach to prepare the CH3NH3PbICl2 perovskite layer by adding lead chloride (PbCl2) to the standard methylamine iodide (MAI) precursor solution and annealing process of the perovskite layer at different temperature. Finally, the Ag/Spiro-OMeTAD/CH3NH3PbI2Cl /mp-TiO2/c-TiO2/FTO/Gl...

    Modeling of Optical Characteristics of Silver Nanoparticles—Water Suspension Subject to Electromagnetic Irradiation

    by Hamid Reza Dehghanpour*
    AFM 2022, Vol 2, Issue 2, 21-25, https://doi.org/10.35745/afm2022v02.02.0004 - Published on June 30, 2022

    Abstract

    Electromagnetic radiation on the suspension of silver-water nanoparticles was simulated using Maxwell equations and the phenomenological equation of extinction crosssection and application of appropriate boundary conditions for nanoparticles with spherical geometry. The outputs of this simulation (extinction coefficient in different conditions) were compared with previous experimental results. The similarity between the simulation outputs and the experimental results indicates the high degree of...

    Pressure and Thickness Dependence of Physical Properties of ZnO:Ga Thin Films by Radio Frequency Magnetron Sputtering

    by Fang-Hsing Wang* and Hua-Tz Tzeng
    AFM 2022, Vol 2, Issue 2, 26-34, https://doi.org/10.35745/afm2022v02.02.0005 - Published on June 30, 2022

    Abstract

    Indium-free transparent conducting oxide films have attracted extensive attention in the field of optoelectronics. Ga-doped ZnO (GZO) thin films are deposited by radio frequency magnetron sputtering on glass substrates at a temperature of 200 °C with ZnO:Ga2O3 (3 wt%). The structural, electrical, and optical properties of the GZO thin films were investigated in terms of deposition pressure and film thickness variations. X-ray diffraction analysis showed that all the prepared GZO films exhibited ...

    Electromechanical Property Calculation of Carbon Nanotubes Using Linear Augmented Cylindrical Wave Method

    by Pavel D’yachkov*
    AFM 2022, Vol 2, Issue 2, 35-47, https://doi.org/10.35745/afm2022v02.02.0006 - Published on June 30, 2022

    Abstract

    Deformations of single-walled carbon nanotubes (SWNTs) change their band structure in the nanoelectromechanical systems. In this study, we investigated the response of the electronic structure of chiral and nonchiral SWNTs (8,7), (9,6), (10,5), (7,7), (11,0), (12,0), and (13,0) to twisting and axial tension modes by using the symmetrized linear augmented cylindrical wave technique. We showed that perturbations of the band structures depend on a “family” index p = (n1 − n2)mod 3 (where p = −1, 0 ...
