Complexation‐Mediated Diffusion‐Limited Crystal Growth: A General Framework for Anisotropic Crystal Growth in Cu‐Based Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
A Complexation‐Mediated Diffusion‐Limited Growth (CMDLG) framework is established to rationalize the anisotropic growth of lead‐free perovskites. Integrating coordination chemistry with mass transport kinetics, this study theoretically derives and experimentally validates that stable iodocuprate complexes induce a diffusion‐limited regime.

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

open access: yesAdvanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

open access: yesAdvanced Functional Materials, EarlyView.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

Collective Dynamics at RHIC

Acta Physica Hungarica A) Heavy Ion Physics, 2003
We discuss the strong collective flow effects, 〈v2〉 and 〈βt〉, observed at RHIC (√sNN=130 GeV). We argue that part of the collectivity could have already developed at partonic stage. To ‘see’ the partonic effects directly, measurements of multi-strange baryons like Ξ, Ω and charmed particles like J/ψ transverse momentum distributions are important. They

Dynamic Collectives and Their Collective Dynamics

2005
Dynamic collectives are discrete dual-aspect phenomena: they may present themselves from different viewspoints as either objects or events, and they arise from the collective action of groups of individual elements. In this paper we outline a formal theory of dynamic collectives and discuss their relevance to a range of GIScience concerns, including ...

Collective dynamics of 'small-world' networks

Nature, 1998
Networks of coupled dynamical systems have been used to model biological oscillators, Josephson junction arrays, excitable media, neural networks, spatial games, genetic control networks and many other self-organizing systems. Ordinarily, the connection topology is assumed to be either completely regular or completely random.

Dynamic test collections

Proceedings of the 29th annual international ACM SIGIR conference on Research and development in information retrieval, 2006
Existing methods for measuring the quality of search algorithms use a static collection of documents. A set of queries and a mapping from the queries to the relevant documents allow the experimenter to see how well different search engines or engine configurations retrieve the correct answers. This methodology assumes that the document set and thus the

Collective Dynamical Properties of Liquid Water

Physical Review Letters, 1988
A theoretical and computer simulation analysis suggests that two collective modes can propagate in liquid water for wave vectors $kg0.64$ ${\mathrm{\AA{}}}^{\ensuremath{-}1}$. The low-frequency mode (ordinary sound) turns out to be associated with the oxygen density fluctuations, whereas the hydrogen density fluctuations are found to be governed by ...
