Using a Supramolecular Approach to Engineer Modular Hydrogel Platforms for Culturing Protoplasts – from General Tissue Engineering to Cellular Agriculture

Advanced Biology, EarlyView.
Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular

No Evidence for Lunar Transit in New Analysis of Hubble Space Telescope Observations of the Kepler-1625 System [PDF]

Astrophysical Journal, 2019
Observations of the Kepler-1625 system with Kepler and the Hubble Space Telescope have suggested the presence of a candidate exomoon, Kepler-1625b I, a Neptune-radius satellite orbiting a long-period Jovian planet.

Prehistory of Transit Searches

, 2018
Nowadays the more powerful method to detect extrasolar planets is the transit method. We review the planet transits which were anticipated, searched, and the first ones which were observed all through history. Indeed transits of planets in front of their

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

GJ 1252 b: A 1.2 R\u3csub\u3e⊕\u3c/sub\u3e Planet Transiting An M3 Dwarf At 20.4 pc [PDF]

, 2020
We report the discovery of GJ 1252 b, a planet with a radius of 1.193 ± 0.074 R⊕ and an orbital period of 0.52 days around an M3-type star (0.381 ± 0.019 M⊕, 0.391 ± 0.020 R⊕) located 20.385 ± 0.019 pc away.

Influence of an Al‐Doped ZnO Interface Layer on the Thermochromic Properties of VO2 Thin Films Deposited by RF Magnetron Sputtering

Advanced Engineering Materials, EarlyView.
Herein the metal‐to‐insulator transition is investigated when depositing vanadium dioxide (VO2) on glass or aluminum‐doped zinc oxide (AZO). O2 flow tuning during the deposition and additional post annealing are effective to control the metal‐to‐insulator transition. However, the VO2/AZO/glass stack reveals an increase in the transition temperature and

Methods for exomoon characterisation: combining transit photometry and the Rossiter-McLaughlin effect

, 2010
It has been suggested that moons around transiting exoplanets may cause observable signal in transit photometry or in the Rossiter-McLaughlin (RM) effect.
