Environmentally Stable and Highly Crystalline MXenes for Multispectral Electromagnetic Shielding up to Millimeter Waves

open access: yesAdvanced Functional Materials, EarlyView.
This study presents excellent EMI shielding effectiveness of highly crystalline HC‐Ti3C2Tx MXene, characterized by high electrical conductivity, outstanding environmental stability, and facile processability, across a multispectral frequency range from 100 kHz to 110 GHz. It is revealed that increasing the thickness and electrical conductivity of MXene

On planet formation in HL Tau [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2015
Abstract We explain the axisymmetric gaps seen in recent long-baseline observations of the HL Tau protoplanetary disc with the Atacama Large Millimetre/Submillimetre Array (ALMA) as being due to the different response of gas and dust to embedded planets in protoplanetary discs. We perform global, three-dimensional dusty smoothed particle

Mediation of Oxidation and Spin States of Fe/P‐CoO2 Core–Shell Structures Catalysts for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐cationic and P‐anionic coordination, as fabricated in Co0.75Fe0.25P/MWCNTs, effectively optimizes the adsorption of OER intermediates (OH*, O*), promoting direct O*─O* coupling and avoiding the formation of unstable OOH* intermediate. This process is accompanied by an asynchronous transfer of electrons and protons, resulting in the formation of a ...

Formation of terrestrial planets in eccentric and inclined giant planet systems [PDF]

open access: yesA&A 613, A59 (2018), 2018
Evidence of mutually inclined planetary orbits has been reported for giant planets these last years. Here we aim to study the impact of eccentric and inclined massive giant planets on the terrestrial planet formation process, and investigate whether it can possibly lead to the existence of inclined terrestrial planets. We have performed 126 simulations

Inside-out Planet Formation. IV. Pebble Evolution and Planet Formation Timescales [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract Systems with tightly packed inner planets (STIPs) are very common. Chatterjee & Tan proposed Inside-out Planet Formation (IOPF), an in situ formation theory, to explain these planets. IOPF involves sequential planet formation from pebble-rich rings that are fed from the outer disk and trapped at the pressure maximum ...

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

open access: yesAdvanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

Understanding the Early Stage of Planet Formation: Design and Demonstration of the Space Experimental Apparatus

open access: yesAerospace, 2023
Planet formation begins with the collision and growth of dust in protoplanetary disks. Concerning the basic cognition of the early stage of planet formation, a long-standing weakness of the research is a comprehensive physical model describing the ...

Collisions of Planetesimals and Formation of Planets [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractWe present preliminary results of models of terrestrial planet formation using on the one hand classical numerical integration of hundreds of small bodies on CPUs and on the other hand—for comparison—the results of our GPU code with thousands of small bodies which then merge to larger ones.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Distinctive Doping Behavior of Conjugated Polymers With Pendant‐Side Conjugation for Enhanced Thermoelectric Properties

open access: yesAdvanced Functional Materials, EarlyView.
Novel conjugated polymers with side‐chain π‐conjugation are developed to enhance organic thermoelectric properties. Remarkably, the pendant doping in the conjugated polymers preserved strong intermolecular ordering in the film states even at high FeCl3 dopant concentrations (16 – 32 mM), achieving a promising power factor > 10 µW m−1 K−2 across a wide ...
