Synergistic Design of Composite Ionogels With Enhanced Thermoelectric Properties, Mechanical Stretchability, and Sustainable Recyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
While flexible TE devices hold promise for converting low‐grade waste heat (e.g., from human skin or electronics) into usable electricity, existing materials suffer from three major limitations: 1) poor mechanical stretchability (failing to match human skin's elongation, ~20–30%), limiting wearability; 2) tradeoffs between thermoelectric efficiency (e ...

Finite‐Time Disturbance Observer‐Based Nonlinear Robust Adaptive Control of Hydraulic Manipulator With Parameter Identification

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Hydraulic manipulators exhibit strong coupling, pronounced nonlinearities, and significant modeling uncertainties, which hinder high‐precision motion control. This paper proposes a finite‐time disturbance observer–based nonlinear robust adaptive control (RAC‐FTDO) framework enhanced by a physically consistent dynamic parameter identification ...

The Development of the Articles in Castilian: A Functional Approach

open access: yesLanguages, 2019
The development of the definite and indefinite articles in Castilian may be regarded as an instance of capitalization or adfunctionalization, following partial exaptation of the Latin demonstrative ille, which involves progressive widening without ...

‘Neopredeljonnyj’ [Indefinite] vs. ‘Neulovimyj’ [Elusive] in Aspect of Categorical Perception

open access: yesНаучный диалог, 2023
The article discusses the phenomenon of categorical perception, the success of which the author suggests can be expressed by the formula “this is exactly X from the category ‘X’.” The lexemes ‘neopredeljonnyj’ [indefinite] vs.

On the syntactic derivation of negative sentence adverbials [PDF]

open access: yes, 1993
We consider recent Government-Binding work on sentential negation, e.g. by Pollock, and evaluate a fundamental assumption made about the syntax of negative clauses.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
