Title: DEVELOPING A NEW INTERATOMIC POTENTIAL AND ATOMISTIC STUDY OF NiTiHf
Authors: Saeed Ataollahi
Published: 2023
Abstract: With the growing demand for high-temperature shape memory alloys (HTSMAs), NiTi-based HTSMAs have gained more attention for implementation in applications at elevated temperatures. Among NiTi-based alloys, NiTiHf has shown to have great potential, by having high transformation temperatures, lower preparation cost and good thermal stability. However, until today, most studies conducted on NiTiHf have focused on a limited range of compositions due to the difficulties and high cost of the experimental studies. Therefore, there exists a lack of comprehensive research on the thermo-mechanical behavior of these HTSMAs. Computational simulations are a very cost-effective and feasible approach for addressing this shortcoming. Among computational methods, molecular dynamics (MD) simulation as an atomistic method offers comprehensive means to explore microstructural phenomena that govern the behavior of material. An essential requirement for performing MD simulations is interatomic potential which serves as the constitutive equations of MD and determine the forces and interactions between atoms. Since no applicable interatomic potential has been developed for NiTiHf, there has not been any progress in MD studies on NiTiHf alloys. Therefore, in this study, a Second Nearest-Neighbor Modified Embedded Atom Method (2NN MEAM) interatomic potential has been developed to accurately represent the NiTiHf ternary system. Initially, the parameters of constituent unary and binary potentials were calibrated by fitting their reproduced results of physical properties to DFT results. Then, the final ternary MEAM potential was checked for reliability and transferability by performing MD simulations. The results showed that the developed potential can accurately capture temperature-induced and stress-induced martensitic phase transformation in NiTiHf. In addition, the lattice parameters and formation energy of different compositions of NiTiHf were obtained and compared with experimental and DFT (Density Functional Theory) results showing a good agreement. Furthermore, using the developed MEAM potential, MD simulations were conducted to analyze the influence of precipitates on the superelasticity and shape memory effect of NiTiHf alloy. The results showed that in the presence of H-phase precipitates, the transformation temperatures increase. In addition, the thermal cycling of NiTiHf under constant stress was simulated and it was found that reducing the temperature rate results in a narrower thermal hysteresis.

Abstract: 关于“疯狂天才”的讨论由来已久，但以实证手段探讨创造力与精神障碍之间的关系始于2O世纪80年代末。通过对创造力与双相谱系障碍、精神分裂谱系障碍以及其他几种类型精神障碍之间相关研究的梳理，可以认为虽没有足够证据表明精神疾患可直接带来个体较高的创造性，但两者之间(尤其是在文学和艺术领域中)的确存在一定程度的共生现象。适度的双相障碍症状和轻微的精神分裂症谱系人格特质与创造力有一定关联，而精神分裂症和严重的双相障碍则会损害个体的创造力。对于创造力和精神障碍存在的这一共生现象，文章从认知加工、遗传与脑机制、人格特质及发展背景几个角度回顾了相应的理论解释和研究证据。

Authors: Todor Kolarov
Keywords: Money laundering, International commercial arbitration, 2012 Recommendations of the Financial Action Task Force
Published: 2022
Abstract: Purpose – The purpose of this paper is to evaluate the existing legal basis, and its practical application, of an arbitrator’s competence to raise on her own initiative money laundering issues.
Design/methodology/approach – The research focusses on presenting the essence of the problem through evaluation of the legal basis for the arbitrators to raise money laundering concerns on their own initiative and the examples of so being done in international commercial arbitration.
Findings – This paper concludes that arbitrators do not presently have a solid legal basis that authorises them to actsua sponte against money laundering. 
Originality/value – The originality and value of this paper lies in its emphasis on theoretical and practical issues related to money laundering in international commercial arbitration. It argues in favour of an explicit recommendation to be incorporated in the 2012 Recommendations of the Financial Action Task Force (FATF) that international commercial arbitrators address money laundering on their own initiative.

Title: DEVELOPMENT OF TWO-GROUP INTERFACIAL AREA TRANSPORT EQUATION FOR CONFINED FLOW - I: MODELING OF BUBBLE INTERACTtONS
Authors: Xiaodong Sun, Seungjin Kim, Mamoru Ishii, Stephen G. Beus
Keywords: Interfacial area, Two-group transport equation, Bubble interaction mechanisms, Bubbly flow, Churn-turbulent flow, Two-fluid model
Abstract: To provide a dynamic and mechanistic constitutive model for the interfacial area concentration in the two-fluid model, a two-group interfacial area transport equation is developed for confined two-phase flows in this series of papers. This paper presents the modeling of bubble interaction mechanisms in the two-group interfacial area transport equation for confined gas-liquid two-phase flow. The transport equation is applicable to bubbly, cap-turbulent, and churn-turbulent flow regimes.
In the two-group interfacial area transport equation, bubbles are categorized into two groups: spherical/distorted bubbles as Group 1 and cap/slug/churn-turbulent bubbles as Group 2. Thus, two sets of equations are used to describe the generation and destruction rates of bubble number density, void fraction, and interfacial area concentration for the two groups of bubbles due to bubble expansion and compression, coalescence and disintegration, and phase change. Five major bubble interaction mechanisms are identified for the gas-liquid two-phase flow of interest, such as, bubble coalescence as a result of random collision driven by turbulent eddies, the entrainment of the bubbles following in the wake of preceding bubbles, bubble break-up due to turbulent impact and surface instability for large bubbles, and small bubble shearing-off at the rim of large bubbles. These interaction mechanisms are analytically modeled as the source/sink terms for the transport equations based on certain assumptions for the confined flow. The models include both intra-group (within a certain group) and inter-group (between two groups) bubble interactions.
A complete set of models close the two-group interfacial area transport equation, which has embedded the mechanisms of the flow regime transition. The comparisons of the prediction by the one-dimensional two-group interfacial area transport equation with experimental data are presented in the second paper of this series.
Title: Crossing the linguistic causeway: A binational approach for translating soundscape attributes to Bahasa Melayu

Abstract: Translation of perceptual descriptors such as the perceived affective quality attributes in the soundscape standard (ISO/TS 12913–2:2018) is an inherently intricate task, especially if the target language is used in multiple countries. Despite geographical proximity and a shared language of Bahasa Melayu (Standard Malay), differences in culture and language education policies between Singapore and Malaysia could invoke peculiarities in the affective appraisal of sounds. To generate provisional translations of the eight perceived affective attributes — eventful, vibrant, pleasant, calm, uneventful, monotonous, annoying, and chaotic — into Bahasa Melayu that is applicable in both Singapore and Malaysia, a binational expertled approach supplemented by a quantitative evaluation framework was adopted. A set of preliminary translation candidates were developed via a four-stage process, firstly by a qualified translator, which was then vetted by linguistics experts, followed by examination via an experiential evaluation, and finally reviewed by the core research team. A total of 66 participants were then recruited cross-nationally to quantitatively evaluate the preliminary translation candidates. Of the eight attributes, cross-national differences were observed only in the translation of annoying. For instance, menjengkelkan was found to be significantly less understood in Singapore than in Malaysia, as well as less understandable than membingitkan within Singapore. Results of the quantitative evaluation also revealed the imperfect nature of foreign language translations for perceptual descriptors, which suggests a possibility for exploring corrective measures.

Keywords: urban fringe farmland, farmland liquidation, the (former) Farmland Bank
Published: 2015
Abstract: The objective of this analysis is to examine a measure for effective utilization of urban fringe farmland through an agricultural land institutional change. The change extended a measure decided by zoning. We focused on Machida-city in Tokyo, which created a plan called the (former) Farmland Bank for farmland liquidation based on that institutional change. The programme works as an intermediation mechanism between farmland owners and farmers who want to rent farmland either as existing farmers and new entrants. In addition to this programme, Abandoned Farmland Programmes promoted agricultural land lease and resolved the problem of abandoned farmland.

Abstract: The on-site generation of hydrogen peroxide (H2O2) attracts much attention for advanced oxidation processes (AOPs) in water treatment. In this work, we reported a novel on-site H2O2 generation reactor combined with ultraviolet (UV) for taste and odor (T&O) compounds removal in drinking water purification systems. The reactor is equipped with a gas diffusion electrode (GDE) accompanied by a proton-conducting solid electrolyte. In this reactor, GDE is used to improve the oxygen transfer efficiency. The porous solid electrolyte is selected for the proton and electron conduction instead of an electrolyte solution, which is crucial for producing pure H2O2 solution. The production rate and concentration of H2O2 can be controlled through adjusting the applied current efficiency and the flow rate of deionized water in a solid chamber. Meanwhile, this system exhibits long-term stability during a continuous operation for 96 h. For the application of the system, the single-cell was assembled into cell stacks, which improved the H2O2 concentration from 780.9 to 2301.3mg⋅L−1, along with the energy consumption reduced from 23.81 to 6.67kWh⋅kg−1 under the applied current density of 30 mA⋅cm−2. To evaluate the water purification performance of this system, the oxidation degradation of 2,4,6-trichloroanisoles (TCA) was conducted using the on-site H2O2 generation process under both static and dynamic flow conditions combined with UV light. The degradation rate of TCA was >95% with its initial concentration of 1μg⋅L−1 under the hydraulic retention time from 10 to 40 min−1 and H2O2 dosage from 10 to 100mg⋅L−1. Meanwhile, almost no residual H2O2 was detected after the degradation process. This study proposed a promising device for drinking water purification

Abstract: Single-atom catalysts (SACs) show great promises for electrochemical CO2 reduction reaction (CRR), but the low density of active sites and the poor electrical conduction and mass transport of the single-atom electrode greatly limit their apparent performances. In this study, we have studied the catalytic performance of a single-atom structured and functional single-atom electrode with high density of exposed active sites and promoted electrical conductivity and mass transport. Herein, we prepared a nickel single-atom electrode consisting of isolated, high-density and low-valent nickel(t) sites anchored on the self-standing N-doped carbon nanotube array with a thickness of 0.32nm. The electrochemical performance of the combination of single-atom nickel(t) sites and self-standing array structure gives rise to an excellent electrocatalytic CO2 reduction performance. The introduction of copper tunes the d-band electron configuration and enhances the adsorption of hydrogen, which impedes the hydrogen evolution reaction. The single nickel atom electrode has been successfully synthesized at 32.87mM·cm−1 and turnover frequency of 1.962h−1 at a mild overpotential of 620mV for CO formation with 97%. Faradic efficiency.
