Low-mass Stars: Their Protoplanetary Disk Lifetime Distribution

open access: yesThe Astrophysical Journal
While most protoplanetary disks lose their gas within less than 10 Myr, individual disk lifetimes vary from 5 Myr. The next challenge is to quantitatively link the diversity of disk lifetimes to the diversity in planets.

High‐Performance Recyclable Polyester Elastomers Through Transient Strain‐Stiffening

open access: yesAdvanced Materials, EarlyView.
Transient strain‐crystallization simultaneously strengthens and toughens block polyester elastomers while conserving recyclability. Using controlled polymerization catalysis and commercial monomers, block polyester elastomers outperform current commercial elastomers, entering a new region of tensile mechanical property space.

Chemistry of Complex Organic Molecules in the V883 Ori Disk Revealed by ALMA Band 3 Observations

open access: yesThe Astronomical Journal
Complex organic molecules (COMs) in protoplanetary disks are key to understanding the origin of volatiles in comets in our solar system, yet the chemistry of COMs in protoplanetary disks remains poorly understood.

The Role of Magnetic Fields in Protostellar Outflows and Star Formation

open access: yesFrontiers in Astronomy and Space Sciences, 2019
The role of outflows in the formation of stars and the protostellar disks that generate them is a central question in astrophysics. Outflows are associated with star formation across the entire stellar mass spectrum.

Tuning Transition Metal 3d Spin state on Single‐atom Catalysts for Selective Electrochemical CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
The introduction of P into a single‐atom Fe catalyst is shown to induce a shift in its electronic configuration toward a high spin state. This is proposed to enhance electron back donation via the dxz/dyz‐π* bond, which improves *COOH adsorption and facilitates the electrochemical conversion of CO2 to CO.

Towards the Rosetta Stone of planet formation

open access: yesEPJ Web of Conferences, 2011
Transiting exoplanets (TEPs) observed just ~10 Myrs after formation of their host systems may serve as the Rosetta Stone for planet formation theories. They would give strong constraints on several aspects of planet formation, e.g.

On the Possibility of Tidal Formation of Binary Planets Around Ordinary Stars [PDF]

open access: yesarXiv, 2010
The planet formation process and subsequent planet migration may lead to configurations resulting in strong dynamical interactions among the various planets. Well-studied possible outcomes include collisions between planets, scattering events that eject one or more of the planets, and a collision of one or more of the planets with the parent star.

Responsive Molecules for Organic Neuromorphic Devices: Harnessing Memory Diversification

open access: yesAdvanced Materials, EarlyView.
Responsive molecules are essential for organic in‐sensor computing devices. This Review highlights recent advances in thedesign, synthesis, and incorporation of electrically, optically, and magnetically responsive molecules in multifunctional synaptic perception devices endowedwith both nonvolatile and volatile memory diversification. By exploiting the
