Spin Dynamics of Excitons and Carriers in Mixed‐Cation MAxFA1–xPbI3 Perovskite Crystals: Alloy Fluctuations Probed by Optical Orientation

open access: yesAdvanced Physics Research, EarlyView.
The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.

Gamut mapping in a high-dynamic-range color space

open access: yes, 2022
Paper 90150A, 7 S.In this paper, we present a novel approach of tone mapping as gamut mapping in a high-dynamic-range (HDR) color space. High- and low-dynamic-range (LDR) images as well as device gamut boundaries can simultaneously be represented within ...

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

open access: yesChemistry – A European Journal, EarlyView.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

New‐Generation Integrated Devices: Multiple‐Energy Utilization and Integration Systems Based on Perovskite Photovoltaics

open access: yesEcoEnergy, EarlyView.
This review highlights emerging integrated energy systems based on perovskite photovoltaics, including PSC–thermoelectric, photovoltaic–electrochemical, self‐charging, and building‐integrated architectures. By coupling multiple energy conversion and storage pathways, these multifunctional platforms enable enhanced solar utilization, improved stability,

From the Field to the Laboratory: The Theory‐Practice Research of Peter J. Carnevale

open access: yesNegotiation and Conflict Management Research, EarlyView., 2020
Abstract As colleagues and collaborators, we reflect on the work and legacy of Peter Carnevale, currently professor at the University of Southern California, and recipient of the 2002 Jeffrey Z. Rubin Theory‐to‐Practice Award of the International Association for Conflict Management (IACM). We review Carnevale’s main contributions, including his work on

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Do we understand children's restlessness? Constructing ecologically valid understandings through reflexive cooperation

open access: yesInternational Journal of Qualitative Studies on Health & Well-Being, 2015
Attention-deficit/hyperactivity disorder (ADHD) is the most widely used children's mental health diagnosis today, but the validity of the diagnosis is controversial, for instance, because it might conceal relational and ecological dimensions of ...

From Ad Hoc to Function: Vancouver Foundation's Journey to Learning Through Evaluation

open access: yesNew Directions for Evaluation, EarlyView.
ABSTRACT This case narrative details the Vancouver Foundation's (VF) journey from ad‐hoc reporting to a core internal learning and evaluation function. Catalyzed by the pandemic and motivated by the increasing need, VF established the Engagement Department to house evaluation independently.

CD8+ T‐cells, CD86+ macrophages and TNF‐α signalling pathways are correlated with fetlock osteoarthritis in racehorses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background There is emerging evidence for the role of the immune system in osteoarthritis (OA) pathophysiology; however, little is known about how immune cells and the synovial transcriptome are altered in naturally occurring equine OA. Objectives To evaluate synovial fluid (SF) and synovial membrane (SM) immune cell populations and the SM ...
