X-Ray Irradiation of the Giant Planet Orbiting the T Tauri Star TAP 26

The Astrophysical Journal
We present new Chandra X-ray observations of TAP 26, a ≈17 Myr old magnetically active weak-lined T Tauri star that has been reported to host a massive planet in a ≈10.8 day orbit.

A Mechanistic Study of Bio‐Based Nanotemplated Carbon Nanofibers Derived From Water Processable Lignin Blends for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
As‐spun carbon materials produced from Lignosulfonate, gelatin, and alginate, selected for water solubility, and ability to produce templated sustainable carbon nanostructures. Gelatin and alginate are sacrificial during thermal processing, allowing the production of engineered high surface area nanostructures, which are further characterized for ...

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Interaction between Winds from Weak-lined T Tauri Stars with Exoplanetary Magnetospheres

The Astrophysical Journal
T Tauri stars, in more advanced stages of evolution, during the final accretion phase of stellar formation, exhibit intense stellar winds and surface magnetic fields with intensities around a kilogauss.

Bonding of Acrylic Pressure‐Sensitive Adhesives and Silicone Elastomers via Surfactant‐Assisted Plasma Activation for Soft Robotics

Advanced Materials Interfaces, EarlyView.
A simple strategy is presented for bonding acrylic PSAs and silicone elastomers by curing surfactant‐doped Ecoflex on oxygen‐plasma‐treated VHB. The interface reaches a maximum strength of 1.6 N/mm (over 20 times that of the control) while retaining material compliance.

Electronic Structure Modulation Induced by Asymmetric Cu─Ni Centers in a π‐Conjugated Triazine MOF

Advanced Materials Interfaces, EarlyView.
A π‐conjugated H3TATB‐based asymmetric bimetallic CuNi‐MOF was developed as an efficient electrocatalyst for alkaline hydrogen evolution. Benefiting from synergistic Cu–Ni interactions, enhanced charge transfer, and stabilized active sites, CuNi‐MOF delivers superior HER performance with low overpotential, improved kinetics, and 24 h durability.

Detecting New Planets in Transiting Systems

, 2006
I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally spaced intervals in time.
