A novel single-step low-temperature pyrolysis method is developed to efficiently remove encapsulated Ni nanoparticles (NPs, 10–50 nm) from both regular-grade (< 5 wt.% metal impurities) and industrial-grade (< 10 wt.% metal impurities) carbon nanotubes (CNTs). This approach eliminates the need for conventional multi-step purification processes, which often involve high-temperature corrosive gas oxidation and acid washing. The new strategy transforms and redistributes encapsulated Ni-NPs into homogeneously sized nanoclusters (NCs, ≈1 nm) that are evenly dispersed on the surface of CNTs. Surface and bulk sensitive spectroscopic analyses reveal the predominant formation of Ni3N-NCs, along with some metallic Ni-NCs. The treated materials demonstrate exceptional electroactivity toward CO2 reduction to CO, with the best-performing CNT-PTFE-Mel-650 sample achieving an ultra-low onset overpotential of −19 mV and 98% CO selectivity in a current density range of 100–700 mA cm−2. This NC catalyst demonstrates 25% lower voltage at 700 mA cm−2 compared to the single atom catalyst (SAC) control. Experimentally verified ab initio molecular dynamics (AIMD) models are simulated, and subsequent density functional theory (DFT) calculations further support the thermodynamic stability of Ni3N-NCs and their favorability for CO2 reduction. This work establishes a new method for creating ligand-free electroactive NCs for efficient electrochemical reactions.

Derrida In Mesopotamia: On The Import Of The Cuneiform Inscriptions In Of Grammatology, Will Greenshields Jul 2025

Derrida In Mesopotamia: On The Import Of The Cuneiform Inscriptions In Of Grammatology, Will Greenshields

CLCWeb: Comparative Literature and Culture

Cuneiform writing has a small but privileged position in Derrida’s Of Grammatology – providing the text with its first two epigraphs. By elucidating the source and import of these inscriptions and evaluating Derrida’s understanding of the cuneiform writing system in reference to more recent grammatological studies, this paper explains the significance of these references to the ancient Near East for Derrida’s arguments regarding the origins of Western metaphysics and logocentrism. In the first part, I analyze Derrida’s brief paragraph on cuneiform writing in Of Grammatology as evincing a “fundamental synaesthesia” of phonetic and non-phonetic elements that problematizes the phonocentric definition …

Morphotectonic And Active Tectonic Properties Of The Yenicekent Travertines With Chibanian–Meghalayan Ages In The Denizli Graben (Türkiye), Ömer Eki̇zoğlu, B. Levent Mesci̇

Turkish Journal of Earth Sciences

Travertine deposits that crop out in the Yenicekent travertine field within the Denizli graben in western Türkiye are described and illustrated. Three morphologies of travertine are identified in this field, comprising fissure-ridge type, range-front, and eroded-sheet type, with each type resulting from deposition by geothermal waters driven by ongoing tectonism. The fissures in the Yenicekent travertine field extend parallel to active normal faults bounding the Denizli basin from the NE-directed Tripolis and Pamukkale faults, and were formed by waters released under tensile stress in the footwall blocks of normal faults. This study aimed to link the chronological development of travertine …

The Effect Of Cognitive Biases And Organizational Constructs On Enterprise Resource Planning Implementation Success In Small And Medium-Sized Enterprises: A Pls-Sem Approach, Michael Davidson

Dissertations

Enterprise Resource Planning (ERP) systems are crucial to enhancing organizational performance, efficiency, and strategic competitiveness in small to medium-sized enterprises (SMEs). ERP adoption in SMEs has been known to fail, with more than 75% of the implementations considered failures. These barriers are compounded by cognitive biases, such as temporal discounting (TD) and optimism bias (OB), which skew the strategic decision-making process. The framework suggested in this paper explains the relationships between top management support (TMS), information quality (IQ), system quality (SQ), user satisfaction (US), optimism bias (OB), and temporal discounting (TD) and their impact on ERP implementation success (EIS) and …

A Model Study On Enhancing The Horizontal Gradient Of Potential Fields With The Vertical Derivative, Luan Thanh Pham, Saulo P. Oliveira, Erdi̇nç Öksüm, Jeferson De Souza Jul 2025

A Model Study On Enhancing The Horizontal Gradient Of Potential Fields With The Vertical Derivative, Luan Thanh Pham, Saulo P. Oliveira, Erdi̇nç Öksüm, Jeferson De Souza

Turkish Journal of Earth Sciences

The total horizontal gradient (THG) and its derivatives are commonly used in interpreting potential fields. Because THG is a nonharmonic function, its vertical derivative (VD) can be consistently computed using, e.g., a finite-difference approximation. The calculation of VD in the wavenumber domain is physically meaningful for harmonic functions, but it provides a pseudovertical derivative (PVD) when applied to nonharmonic fields that can be used in some edge detectors, such as THG. Through experiments with synthetic and field datasets, we evaluated the performance of the PVD of THG in the tilt angle of THG (TAHG) and fast sigmoid-based edge detector (FSED). …


On Reference Accuracy: Clarification Of The Original Data, İrem Eli̇tez, Cenk Yaltirak Jul 2025

On Reference Accuracy: Clarification Of The Original Data, İrem Eli̇tez, Cenk Yaltirak

Turkish Journal of Earth Sciences

Although it is claimed that the same data was correctly attributed to Alçiçek (2007) in Elitez and Yaltırak (2023), no age data from Alçiçek (2007) were actually used in that study. In fact, the stratigraphic interpretation proposed by Alçiçek (2007) exhibits notable discrepancies with the conclusions presented by Elitez and Yaltırak (2023). Alçiçek (2007) defines the geological units overlying the basement as the Eşen Formation (comprising the Çetilidüz, Çaykenarı, and Kocaçay members) and Quaternary units. Based on the fossil Palaeotragus rouenii, the author suggests that the Neogene succession begins with Late Miocene alluvial-fan conglomerates, sandstones, and mudstones, whereas lacustrine sedimentation …

Citing The Citer: A Way To Claim Original Data, Mehmet Ci̇hat Alçi̇çek

Turkish Journal of Earth Sciences

In Elitez and Yaltırak (2024, p. 3), the “Upper Miocene” age data for the Eşen Basin fill is cited from Elitez and Yaltırak (2023). However, in that work, the same data was correctly attributed to Alçiçek (2007), which is the original source. Citing a secondary source instead of the original one is avoided in scientific writing. This letter aims to correct this citation practice.

Recognizing The Charter Value Of Employee Freedom Of Association At Common Law, Kevin Banks Jul 2025

Recognizing The Charter Value Of Employee Freedom Of Association At Common Law, Kevin Banks

Osgoode Hall Law Journal

This article systematically explores, for the first time in the published literature, how the development of the common law of employment could advance in light of the Charter values doctrine, focusing on freedom of association. It contends that courts must scrutinize the common law’s impairments of that freedom, and unless they are necessary to similarly important common law values, eliminate them where it is possible to do so within courts’ powers to incrementally change it. A number of such paths are open. If asked to do so, courts probably can and should provide Canadians with a common law of employment …
