GRB Energetics in the Swift Era

open access: yes, 2008
We examine the rest frame energetics of 76 gamma-ray bursts (GRBs) with known redshift that were detected by the Swift spacecraft and monitored by the satellite's X-ray Telescope (XRT). Using the bolometric fluence values estimated in Butler et al. 2007b

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

El discurso satírico como filtro de la política en la literatura: El caso de Swift y Bulgákov.

open access: yesPensamiento al Margen, 2016
La literatura es una de las principales manifestaciones artísticas del hombre. Esta, por lo tanto, está relacionada con la vida de este. La literatura recoge, entonces, al hombre y lo que lo rodea.
