Meteorites and cosmic dust: Interstellar heritage and nebular processes in the early solar system

open access: yesEPJ Web of Conferences, 2012
Small solar system bodies like asteroids and comets have escaped planetary accretion. They are the oldest and best preserved witnesses of the formation of the solar system.

Chemical signatures of planets: beyond solar-twins [PDF]

open access: yes, 2013
Elemental abundance studies of solar twin stars suggest that the solar chemical composition contains signatures of the formation of terrestrial planets in the solar system, namely small but significant depletions of the refractory elements.

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

open access: yesAdvanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

Market Formation in Turkish Solar Electricity Generation: Technology Innovation System Approach

open access: yesİzmir İktisat Dergisi, 2023
The Technological Innovation System (TIS) is a theoretical approach to the analysis of a new technology's diffusion dynamics. The development and establishment of market-related structures are essential for maturing a TIS and its long-term success ...

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Silica-rich volcanism in the early solar system dated at 4.565 Ga

open access: yesNature Communications, 2018
Achondritic meteorites can record volcanism and crust formation on planetesimals in the early Solar System. Here, the authors date the Northwest Africa 11119 meteorite with an Al-Mg age of 4564.8 ± 0.3 Ma indicating that this is the earliest evidence of ...

Observations of the D/H ratio in Methane in the atmosphere of Saturn's moon, Titan - where did the Saturnian system form? [PDF]

open access: yes, 2013
The details of the Solar system's formation are still heavily debated. Questions remain about the formation locations of the giant planets, and the degree to which volatile material was mixed throughout the proto-planetary system.

Core-Accretion Model Predicts Few Jovian-Mass Planets Orbiting Red Dwarfs

open access: yes, 2004
The favored theoretical explanation for giant planet formation -- in both our solar system and others -- is the core accretion model (although it still has some serious difficulties). In this scenario, planetesimals accumulate to build up planetary cores,
