Evidence for Environmental Changes in the Submillimeter Dust Opacity [PDF]

open access: yes, 2012
The submillimeter opacity of dust in the diffuse interstellar medium (ISM) in the Galactic plane has been quantified using a pixel-by-pixel correlation of images of continuum emission with a proxy for column density.

A Physiological Microfluidic Blood–Brain‐Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A human microfluidic blood‐brain barrier (mBBB) model enables spatially resolved comparison of nanoparticle trafficking. Extracellular vesicles (EVs), liposomes, and nanoplastics exhibit distinct transport and disruption behaviors, revealing that membrane composition and uptake pathways govern BBB interaction.

Corneal Penetrating Injury Following Combat-Related Trauma – A Clinical Case Report

open access: yesOkulistyka
Introduction Ocular trauma is a leading cause of unilateral blindness worldwide, with about 1.6 million people losing their vision annually. Despite the small surface area of the eye, the risk of injury during armed conflicts is disproportionately high ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Representation and exposition: being and walking along the designs of Boulevard 24 de Mayo in Quito, Ecuador (1991-2012)

open access: yesARQUISUR Revista
The present study reflects on the last two urban-architectural proposals in Boulevard 24 de Mayo in Quito, Ecuador, which were developed in 1991 and 2012, respectively. We aim at identifying the conditions of being and walking along that urban space with

Mixed quotation: The grammar of apparently transparent opacity

open access: yesSemantics and Pragmatics, 2014
The phenomenon of mixed quotation exhibits clear signs of both the apparent transparency of compositional language use and the opacity of pure quotation.

Detailed Opacity Calculations for Stellar Models

open access: yes, 2018
Radiative opacity is an important quantity in the modeling of stellar structure and evolution. In the present work we recall the role of opacity in the interpretation of pulsations of different kinds of stars.

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

A Colloidal Quantum Dot Thermistor and Bolometer

open access: yesAdvanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...
