Examining drivers of NFT purchase intention: The impact of perceived scarcity and risk.
Acta Psychol (Amst)
August 2024
The emergence of non-fungible tokens (NFTs) has elicited both excitement and apprehension among consumers, who find themselves influenced by the perceived scarcity and the perceived risks surrounding these novel digital assets. This study investigates the factors influencing consumer adoption of NFTs by integrating the concepts of perceived scarcity and perceived risks within the theoretical framework of the Theory of Planned Behavior (TPB). Employing structural equation modeling, the research evaluates the impact of perceived scarcity, perceived ease of use, attitudes, subjective norms, perceived behavioral control, and perceived risk on NFT purchase intentions.

The hardness data were sampled from the flat and edge surfaces of the samples. In addition, the effect of hardness characters after the ultraviolet (UV) curing process was analyzed.

- - Additive manufacturing (AM) offers lightweight, customized materials and is eco-friendly, used in fields like medicine and aerospace; fused deposition modeling (FDM) is a popular, cost-effective method with lower material waste.
- - This study focuses on 3D printing with FDM, examining how changes in printing temperature and filling percentage affect the properties of polylactic acid (PLA) material through tensile and hardness tests.
- - Results indicate that higher filling percentages and temperatures improve the material's tensile properties and hardness, while UV curing significantly increases rigidity but decreases strength and toughness, aiding research for sustainable manufacturing.
Article Synopsis
- The study focused on improving the efficiency of Fused Deposition Modeling (FDM) using polylactic acid (PLA) by experimenting with various printing and raster angles to evaluate their impact on tensile properties.
- The investigation also examined how ultraviolet (UV) curing affected the PLA, revealing that UV curing increased brittleness and decreased elongation.
- Findings indicated that both printing parameters and UV curing significantly influenced the tensile strength and modulus of PLA specimens, which is valuable for researchers aiming to enhance the sustainability of PLA and FDM technology.
Article Synopsis
- * The study examines how these materials perform under different loads (tension, compression, bending, thermal) across various printing temperatures and speeds.
- * Findings reveal that PLA shows better mechanical properties than PETG under tension and compression, but PETG outperforms PLA in thermal deformation. This research provides valuable insights for improving sustainability in 3D printing processes.
Industries' air pollution causes serious challenges to modern society, among them exhaust gases from internal combustion engines, which are currently one of the main sources. This study proposes a non-thermal plasma (NTP) system for placement in the exhaust system of internal combustion engines to reduce the toxic contaminants (HC, CO, and NO) of exhaust gases. This NTP system generates a high-voltage discharge that not only responds to the ion chemical reaction to eliminate NO and CO, but that also generates a combustion reaction at the local high temperature of plasma to reduce HC.
