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.

Reduced plasma desmosterol‐to‐cholesterol ratio and longitudinal cognitive decline in Alzheimer's disease

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2015
Background We here examined whether plasma desmosterol‐to‐cholesterol ratio (DES/CHO) is decreased in patients with Alzheimer's disease (AD) and investigated the association between plasma DES/CHO and longitudinal cognitive decline.

Trifluoromethoxylated Electron Acceptor Enabling Ternary Organic Solar Cells with over 20% Power Conversion Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...

Estilo desornamentado, arquitetura-chã: alguns aspectos do renascimento na Península Ibérica

open access: yesPós. Revista do Programa de Pós-Graduação em Arquitetura e Urbanismo da FAUUSP, 2011
No século 16, na Península Ibérica, a assimilação do romano impulsiona uma corrente arquitetônica na qual um progressivo classicismo e o despojamento decorativo anunciam a chegada do chamado Renascimento. Ainda que possuam suas peculiaridades, tanto o estilo-chão português quanto o desornamentado espanhol se apóiam em doutrinas arquitetônicas de origem

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

open access: yesAdvanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.
