Sol–Gel Synthesis of Ca2.5Ag0.3Sm0.2Co4O9 Semiconducting Materials for Thermoelectric Applications in Aerospace Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.

New Developments in the Field of Production and Application of Multi‐Material Wire Arc Additive Manufacturing Components: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
The utilization of direct energy deposition (DED)‐arc additive manufacturing processes in industrial applications is increasing, and these processes have the potential for multi‐material applications. This work provides a overview of the state of research in DED‐arc made functional graded structures, to establish a link to potential industrial ...

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

open access: yesAdvanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Conversation analysis

The Routledge Handbook of Translation and Methodology, 2022
Since the late 1990s, translation and interpreting studies has looked at CA with increasing interest, especially in the area of dialogue interpreting (DI). DI is a form of interaction where speakers with little or no knowledge of each other’s language interact with the help of a bilingual interlocutor who translates for them.

Conversation analysis

The Bloomsbury Handbook of Discourse Analysis, 2021
Abstract Conversation analysis offers an inductive approach to the analysis of classroom interaction. With its roots in ethnomethodology, conversation analysis is underpinned by some key principles that focus on how the learning of mathematics is made visible through teachers’ and students’ interactions.

conversation analysis and interactional linguistics

The Encyclopedia of Applied Linguistics, 2012
Interactional linguistics is grounded on the premise that language should not be analyzed in terms of context-free linguistic structures but as a resource for the accomplishment of actions in social interaction. With this in mind, interactional linguistics takes an interdisciplinary approach to a linguistic analysis that aims at an understanding of how

Conversation analysis

Qualitative Research in Health Care, 2019
Conversation Analysis focuses on spoken language as the most potent tool of social action and on the mechanisms that regulate conversation as they are used to accomplish social goals, providing insights into how interpreters contribute to the construction of participants’ roles and identities by negotiating conversational rights, managing coordination ...

Analysis and conversion of documents

Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002
This paper deals with the use of grammatical formalisms to recognise the physical and the logical structures of a composite document. We propose a new system based on W-grammar for document analysis and conversions. As an application the system identifies printed "summaries" and converts them into machine readable form such as the hypertext markup ...
