Accurate classification of 75 counterparts of objects detected in the 54 month Palermo Swift/BAT hard X-ray catalogue

open access: yes, 2013
Through an optical campaign performed at 4 telescopes located in the northern and the southern hemispheres, we have obtained optical spectroscopy for 75 counterparts of unclassified or poorly studied hard X-ray emitting objects detected with Swift/BAT ...

Type Iax SNe as a few-parameter family [PDF]

open access: yes, 2018
We present direct spectroscopic modeling of five Type Iax supernovae (SNe) with the one dimensional Monte Carlo radiative transfer code TARDIS. The abundance tomography technique is used to map the chemical structure and physical properties of the SN ...

Un-Mögliche Solidarität: Zivile Seenotrettung zwischen radikaler Demokratie und kolonialen Kontinuitäten

open access: yesGenealogy+Critique, 2023
Drawing from Jacques Derrida's notion of the impossible, the paper discusses different understandings of solidarity. It questions a notion of solidarity where it is deemed possible only under conditions of similarity.

3D Model Atmospheres for Extremely Low-Mass White Dwarfs [PDF]

open access: yes, 2015
We present an extended grid of mean three-dimensional (3D) spectra for low-mass, pure-hydrogen atmosphere DA white dwarfs (WDs). We use CO5BOLD radiation-hydrodynamics 3D simulations covering Teff = 6000-11,500 K and logg = 5-6.5 (cgs units) to derive ...

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Simple model for water wash performance in amine scrubbing for CO2 capture

open access: yesCarbon Capture Science & Technology
In amine-based capture systems, a water wash is necessary to remove gaseous amine to minimize atmospheric emissions and maximize amine recovery. Water wash simulation requires rigorous thermodynamic and kinetic models like those for absorption and ...

Deciphering Intricacies in Directional CO2 Conversion From Electrolysis to CO2 Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review will delve into the inherent connections and distinctions of CO2‐directed conversion in ECO2RR and CO2 batteries, in terms of product types, catalyst selection, catalytic mechanisms, and electrochemical performances, while proposing a benchmarking framework for the evaluation of CO2 batteries and innovative CO2 battery configurations for ...

Neoliberalism in Ecuador after Correa: A surprise turn or according to economic elites' plan?

open access: yesEuropean Review of Latin American and Caribbean Studies, 2019
This article examines economic elites’ reactions to early efforts by Ecuador’s left government to limit their clout. Elites developed an infrastructure of dissent to promote their interests. Some chambers of commerce and industry adapted their strategies

B-cell antigen receptor expression and phosphatidylinositol 3-kinase signaling regulate genesis and maintenance of mouse chronic lymphocytic leukemia

open access: yesHaematologica, 2022
Chronic lymphocytic leukemia (CLL) is a frequent lymphoproliferative disorder of B cells. Although inhibitors targeting signal proteins involved in B-cell antigen receptor (BCR) signaling constitute an important part of the current therapeutic protocols
