Repair in Socio-technical Systems. The Repair of a Machine Breakdown that Turned into the Repair of a Shop

open access: yesTecnoscienza, 2016
This article aims to deepen our understanding of repair work in sociotechnical systems. It is based on three main bodies of literature, which are specifically attentive to materiality: STS studies on repair, studies of breakdowns and technological change

Biphasic Co‐Delivery of Curcumin and 5‐FU using 3D‐Printed Dissolving Microneedles for Skin Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Using pixel‐aware digital light processing, the authors created high‐resolution, dissolvable microneedles from a PEGDA/VP matrix. These microneedles encapsulate curcumin and 5‐fluorouracil and dissolve in the skin, co‐delivering drugs directly to tumours.

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 ...

Exemplaire Pascal

open access: yesLes Dossiers du GRIHL
The famous pensée on examples (Sellier 454) usually puzzles the reader with the false symmetry of these propositions: “When one wishes to demonstrate a general principle, one must provide the specific rule for a particular case.

Revised Line Profile Function for Hydrogenic Species

open access: yesOpen Astronomy, 2012
Analytical series expansions for the hydrogenic spectral line profile functions are derived starting from the three single expressions, obtained by integrating twice the convolution of the Holtsmark, Lorentz and Doppler line profile functions.

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 ...

Alinhamento e estratégias de relativização

open access: yesDELTA: Documentação de Estudos em Lingüística Teórica e Aplicada
RESUMO O objetivo deste trabalho é examinar a hipótese de que a seleção entre as diferentes estratégias de relativização disponíveis na gramática do português é motivada por um grau maior ou menor de transparência entre forma e conteúdo, o que implica ...

A New Implementation of the STA Method for the Calculation of Opacities of Local Thermodynamic Equilibrium Plasmas

open access: yesAtoms, 2018
We present opacity calculations with the newly developed STAR code, which implements the Super-Transition-Array (STA), with various improvements. The model is used to calculate and analyze local thermodynamic equilibrium opacities of mid and high Z ...

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...
