In Vitro and Ex Vivo Models for Assessing Drug Permeation across the Cornea

Inès de Hoon, Rabah Boukherroub, Stefaan de Smedt, Sabine Szunerits, Félix Sauvage

Drug permeation across the cornea remains a major challenge due to its unique and complex anatomy and physiology. Static barriers such as the different layers of the cornea, as well as dynamic aspects such as the constant renewal of the tear film and the presence of the mucin layer together with…

Dual Photonic Structures Enable High‐Performance Semitransparent Organic Photovoltaics with Enhanced Light Utilization

Baozhong Deng, Youyang Shen, Kaiwen Zheng, Chi Wang, Gaëtan Lévêque, Tao Xu

Semitransparent organic photovoltaics (ST-OPVs) offer promising prospects for self-powered greenhouses and building-integrated photovoltaic systems. However, a remaining critical challenge is to balance the two competing indexes of power conversion efficiency (PCE) and average visible transmittance…

Effects of functionalized magnetic graphene oxide on the visible-light-induced photocatalytic activity of perovskite-type MTiO3 (M= Zn and Mn) for the degradation of Rhodamine B

Anasheh Mardiroosi, Ali Reza Mahjoub, Amir Hossein Cheshme Khavar, Rabah Boukherroub, Mika Sillanpää, Parminder Kaur

This work reports the synthesis of a variety of perovskite-type titanates (MTiO3, M= Zn, and Mn) and their loading on functionalized magnetic graphene oxide (EDFG) to produce MTiO3@EDFG nanocomposites. These materials were fully characterized by FT-IR and Raman spectroscopy, XRD, SEM, TEM, N2…

On the Practical Limitations for the Generation of Gunn Oscillations in Highly Doped GaN Diodes

S. García-Sánchez, M. Abou Daher, M. Lesecq, L. Huo, R. Lingaparthi, D. Nethaji, K. Radhakrishnan, I. Íñiguez-De-La-Torre, B. Vasallo, S. Pérez, T. González, J. Mateos

Planar Gunn diodes based on doped GaN active layers with different geometries have been fabricated and characterized. Gunn oscillations have not been observed due to the catastrophic breakdown of the diodes for applied voltages around 20–25 V, much below the bias theoretically needed for the onset…

JAXA’s Hayabusa2 mission brought back 5.4 g of material from the surface of the carbonaceous asteroid Ryugu. Some grains show evidence of a modified surface attributed to space-weathering effects [1], which result from solar-wind irradiation and/or micrometeoroid bombardment. In collaboration with…
