Self‐Aligning Metallic Vertical Interconnect Access Formation through Microlensing Gas Phase Electrodeposition controlling Airgap and Morphology (Adv. Electron. Mater. 1/2023)

open access: yesAdvanced Electronic Materials, Volume 9, Issue 1, January 2023., 2023
Vertical Interconnects In article number 2200838, Heiko O. Jacobs and co‐workers demonstrate how gas ions and metal particles leave a spark discharge generator in a plasma jet to deposit on a chip in a self‐aligning manner. The charge gas ions float the insulating resist on top of an oxide/metallization stack to guide the metal nanoparticles with a ...

Microlensing search for extra solar planets [PDF]

open access: yes, 2015
Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

The road toward imaging a black hole: A personal perspective

open access: yesNatural Sciences, Volume 2, Issue 4, October 2022., 2022
The article describes the authors personal journey towards developig the Event Horizon Telescope and the first image of a black hole. Left: predcition made by the author and collaborators proposing the black hole imaging in 2000. Right: the two images observed and published by the Event Horizon Telescope in 2019 and 2022.

Mushroom microlenses: optimized microlenses by reflow of multiple layers of photoresist [PDF]

open access: yesIEEE Photonics Technology Letters, 1997
A novel type of photoresist microlenses is conceived. The characteristic of these lenses is their mushroom shape: the lens dome is located at a certain controllable distance from the substrate, and the curvature of the lens is larger than that of traditional truncated-sphere lenses.

Microlensing for extrasolar planets : improving the photometry [PDF]

open access: yes, 2013
Gravitational Microlensing, as a technique for detecting Extrasolar Planets, is recognised for its potential in discovering small-mass planets similar to Earth, at a distance of a few Astronomical Units from their host stars.

Microlensing and Its Degeneracy Breakers: Parallax, Finite Source, High-Resolution Imaging, and Astrometry

open access: yesUniverse, 2017
First proposed by Paczynski in 1986, microlensing has been instrumental in the search for compact dark matter as well as discovery and characterization of exoplanets.

Identifying interesting planetary systems for future X‐ray observations

open access: yesAstronomische Nachrichten, Volume 343, Issue 4, May 2022., 2022
Abstract X‐ray observations of star–planet systems are important to grow our understanding of exoplanets; these observations allow for studies of photoevaporation of the exoplanetary atmosphere, and in some cases even estimations of the size of the outer planetary atmosphere.

Effervescence‐Inspired Self‐Healing Plastrons for Long‐Term Immersion Stability

open access: yesAdvanced Functional Materials, Volume 32, Issue 4, January 19, 2022., 2022
Underwater performance of superhydrophobic/superamphiphobic surfaces relies on the robustness and durability of the gas‐layer (plastron). A simple and scalable technique of effervescence‐inspired on‐demand plastron repair is presented. Surfaces do not suffer from any performance‐losses even after 2 months of continuous immersion.

Scintillations And Microlensing [PDF]

open access: yesSymposium - International Astronomical Union, 1996
It is shown how the theory of scintillation may be applied to treat gravitational lensing. The theory is applied to microlensing by a system of N point masses. It is shown that scintillation theory reproduces a known result for the angular broadening due to multiple microlensing.

Comparison of Rutherford's atomic model with the Standard Model of particle physics and other models

open access: yesJournal of the Royal Society of New Zealand, Volume 51, Issue 3-4, Page 538-556, September ‐ December 2021., 2021
ABSTRACT Ernest Rutherford is known almost universally as the discoverer of the structure of the atom. He is less well known for his discovery of the proton. Even less well known is a set of hypotheses on the structure of matter that was proposed by Newton 300 years ago.
