Engineering Free Volume within Frontal Ring‐Opening Metathesis Polymerization via Pendant Plasticization

open access: yesAdvanced Materials, EarlyView.
Norbornene‐based copolymers with tunable n‐alkyl pendant length provide control over matrix free volume, enabling elastomeric materials via frontal ring‐opening metathesis polymerization (FROMP). ABSTRACT Frontal ring‐opening metathesis polymerization (FROMP) enables rapid, energy‐efficient access to high‐performance thermosets and thermoplastics, but ...

Room‐Temperature, Photo‐Densified High Refractive Index Titanium Oxide Thin Films for Solution‐Processed Flexible Bragg Mirrors and Microcavity OLEDs

open access: yesAdvanced Optical Materials, EarlyView.
This paper presents the room‐temperature fabrication of solution‐processed, high refractive index TiOX thin films via photo‐densification. Using these films, flexible Bragg mirrors are demonstrated on PET substrates, achieving a high reflectivity of 96% at 450 nm.

On the Cauchy Completeness of the Constructive Cauchy Reals [PDF]

open access: yes, 2015
It is consistent with constructive set theory (without Countable Choice, clearly) that the Cauchy reals (equivalence classes of Cauchy sequences of rationals) are not Cauchy complete.

Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy

open access: yesAdvanced Photonics Research, EarlyView.
Optical frequency combs represent a breakthrough in metrology, and comb mode selection and power scaling are important issues for highly sensitive spectroscopy. This article reviews the development of a spectrally peaked optical frequency comb using the novel phenomenon of spectral peaking for highly sensitive spectroscopy.

Co-constructive Logics for Proofs and Refutations

open access: yesStudia Humana, 2015
This paper considers logics which are formally dual to intuitionistic logic in order to investigate a co-constructive logic for proofs and refutations. This is philosophically motivated by a set of problems regarding the nature of constructive truth, and

Emotions in specialised genres: Power, manipulation and persuasion from the Affect Spectrum Theory

open access: yesEstudios de Lingüística, 2022
This paper seeks to examine professional genres from a novel perspective linking social constructivism and basic emotion theory, making the assumption that emotions are intrinsically social, and that social phenomena (such as professional ...

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

open access: yesAdvanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...

Quantum indeterminate set theory: a novel framework for complex-valued uncertainty and phase-based decision modeling

open access: yesAIMS Mathematics
We introduce the quantum indeterminate set (QIS), a novel mathematical framework that integrates complex-valued membership functions and phase-based interference into classical and generalized set theory.

Motion Control of a Quadrotor Aircraft via Singular Perturbations

open access: yesInternational Journal of Advanced Robotic Systems, 2013
In this paper, a new motion controller for a quadrotor aircraft is introduced. A reformulation of the control inputs of the dynamic model is discussed and then the control algorithm is given in a constructive form.
