Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Theorising the gift through visual culture [PDF]

open access: yes, 2005
This thesis discusses the gift in terms of presence and interpretation using varied examples of image that form a visual culture. It contextualises the term giftness by analysing its use and our socio-cultural understanding of its function as it relates ...

Semantic Modeling in Materials Science and Engineering With Platform MaterialDigital Core Ontology 3.0

open access: yesAdvanced Engineering Materials, EarlyView.
The community‐driven Platform MaterialDigital Core Ontology (PMDco) 3.0 is introduced as a Basic Formal Ontology‐aligned semantic backbone for the processing–structure–properties paradigm in Materials Science and Engineering. Modular engineering, automated releases, and validation workflows are highlighted and key semantic patterns for materials ...

Beyond the Freakonomics of Religious Liberty

open access: yesChanging Societies & Personalities, 2017
The paper critiques the prevailing liberal market economy models of religious liberty and religious encounter. In place of market models, this paper argues that values inscribed in gift exchange, hospitality, guest/host relations, in many cases, and to ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Repackaging fan culture: The regifting economy of ancillary content models [symposium]

open access: yesTransformative Works and Cultures, 2009
As "Web 2.0 companies speak about creating communities around their products and services, rather than recognizing that they are more often courting existing communities with their own histories, agendas, hierarchies, traditions, and practices" (Jenkins ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Marginalia: algumas notas adicionais sobre o dom

open access: yesMana, 1996
Prosseguindo a análise do dom, este artigo busca ultrapassar as visões fenomenológica, estruturalista e economicista do fenômeno. Para tanto, desloca o eixo de interrogação na direção do tempo e da incerteza ligados ao intervalo entre o dom e o contradom,
