Abstract This contribution reports, for the first time, on an entirely green bio-engineering approach for the biosynthesis of single phase crystalline 1-D nano-scaled calcite CaCO3. This was validated using H2O as the universal solvent and natural ex

Invited Article: Ultra-broadband terahertz coherent detection via a silicon nitride-based deep sub-wavelength metallic slit

Autor: A. Tomasino, R. Piccoli, Y. Jestin, S. Delprat, M. Chaker, M. Peccianti, M. Clerici, A. Busacca, L. Razzari, R. Morandotti

Publikováno v: APL Photonics, Vol 3, Iss 11, Pp 110805-110805-8 (2018)

We present a novel class of CMOS-compatible devices aimed to perform the solid-state-biased coherent detection of ultrashort terahertz pulses, i.e., featuring a gap-free bandwidth at least two decades-wide. Such a structure relies on a 1-µm-wide

Thermodynamics of self-oscillations in VO2 for spiking solid-state neurons

Autor: D. Lepage, M. Chaker

Publikováno v: AIP Advances, Vol 7, Iss 5, Pp 055203-055203-6 (2017)

Neuron-like mechanisms under DC bias are observed in two-port VO2 pads. We investigate these self-oscillations responses for different types of VO2 and uncovered an underlying story common to all materials on how self-oscillations arise. From the ele

As mudanças no uso do solo e o risco de desertificação: o exemplo de Marrocos

Autor: C.O.A. Coelho, A. Laouina, A.J.D. Ferreira, M. Chaker, R. Naciri, R. Naafa, A.K. Boulet

Publikováno v: Territorium: Revista Portuguesa de riscos, prevenção e segurança, Iss 7 (2000)

Neste artigo analisam-se os processos hidrológicos e erosivos conducentes à degradação do solo e desertificação nas áreas de Ksar El Kebir (Alcácer Quibir) e Ben Slimane no Norte de Marrocos, áreas sujeitas a mudanças no uso do solo e a pre

TGF-β1 Drives Inflammatory Th Cell But Not Treg Cell Compartment Upon Allergen Exposure

Autor: Stephanie Musiol, Francesca Alessandrini, Constanze A. Jakwerth, Adam M. Chaker, Evelyn Schneider, Ferdinand Guerth, Benjamin Schnautz, Johanna Grosch, Ileana Ghiordanescu, Julia T. Ullmann, Josephine Kau, Mirjam Plaschke, Stefan Haak, Thorsten Buch, Carsten B. Schmidt-Weber, Ulrich M. Zissler

Publikováno v: Frontiers in Immunology, Vol 12 (2022)

TGF-β1 is known to have a pro-inflammatory impact by inducing Th9 and Th17 cells, while it also induces anti-inflammatory Treg cells (Tregs). In the context of allergic airway inflammation (AAI) its dual role can be of critical importance in influen

Genome-Wide Gene Expression Analysis Reveals Unique Genes Signatures of Epithelial Reorganization in Primary Airway Epithelium Induced by Type-I, -II and -III Interferons

Autor: Anna Erb, Ulrich M. Zissler, Madlen Oelsner, Adam M. Chaker, Carsten B. Schmidt-Weber, Constanze A. Jakwerth

Publikováno v: Biosensors, Vol 12, Iss 11, p 929 (2022)

Biosensors such as toll-like receptors (TLR) induce the expression of interferons (IFNs) after viral infection that are critical to the first step in cell-intrinsic host defense mechanisms. Their differential influence on epithelial integrity genes,
