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.

Exchange Rates and Product Variety [PDF]

open access: yes
We study the role of exchange rate variability in the firm's choice of whether to o¤er one or two varieties. We show that variability induces the firm to vertically segment markets (offer two varieties).

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.

Labour Incentive Schemes in a Cournot Duopoly with Simple Institutional Constraints [PDF]

open access: yes
This paper studies equilibrium incentive contracts in a Cournot duopoly, in which institutional arrangements constrain firms to pay (risk-neutral) workers a given salary. In this context, performance-related-pay (PRP) and relative performance evaluation (

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

open access: yesAdvanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

CHARACTERISTICS OF THE DECLINING U.S. AGRICULTURAL TRADE SURPLUS [PDF]

open access: yes
The U.S. agricultural trade surplus has fallen from $26.9 billion in 1996 to $7.3 billion in 2004, and it is shrinking even further in 2005. The objective of this paper is to examine the characteristics of the decreasing agricultural trade surplus and ...
