A tunable microcavity

open access: yesJournal of Applied Physics, 2011
We present a generic microcavity platform for cavity experiments on optically active nanostructures, such as quantum dots, nanocrystals, color centers, and carbon nanotubes. The cavity is of the Fabry-Pérot type with a planar back mirror and a miniature concave top mirror with radius of curvature ∼ 100 μm.

Tunable Nanoplasmonic Photodetectors

open access: yesNano Letters, 2022
Visible and infrared photons can be detected with a broadband response via the internal photoeffect. By using plasmonic nanostructures, i.e. nanoantennas, wavelength selectivity can be introduced to such detectors through geometry-dependent resonances.

Static and Dynamic Analysis of Electrostatically Actuated MEMS Shallow Arches for Various Air-Gap Configurations

open access: yesMicromachines, 2021
In this research, we investigate the structural behavior, including the snap-through and pull-in instabilities, of in-plane microelectromechanical COSINE-shaped and electrically actuated clamped-clamped micro-beams resonators.

On the Efficiency Enhancement of an Actively Tunable MEMS Energy Harvesting Device

open access: yesVibration, 2022
In this paper, we propose an active control method to adjust the resonance frequency of a capacitive energy harvester. To this end, the resonance frequency of the harvester is tuned using an electrostatic force, which is actively controlled by a voltage ...

The dielectric studies on sol–gel routed molybdenum oxide thin film [PDF]

open access: yesJournal of Advanced Dielectrics, 2017
The influence of temperature on the dielectric properties of sol-gel routed spin-coated molybdenum trioxide (MoO3) thin film has been investigated. Prepared films were annealed at temperatures 250∘C, 350∘C and 400∘C.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Interferon beta drives therapy resistance in a patient‐derived model of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...
