Wafer‐Scale Synthesis of Molecularly Engineered 2D Covalent Organic Framework Films for Highly‐Sensitive and Rapid‐Response Humidity Sensing

open access: yesAdvanced Materials, EarlyView.
We report molecularly engineered 2D COF films for high‐performance humidity sensors. The developed COFTPT‐THTA ultrathin film features triazine‐functionalized π‐conjugated backbones and high‐density surface hydroxyl groups. This unique architecture facilitates an electron‐proton coupled transport mechanism.

High-Precision Measurement of Rydberg State Hyperfine Splitting in a Room-Temperature Vapour Cell [PDF]

open access: yes, 2013
We present direct measurements of the hyperfine splitting of Rydberg states in rubidium 87 using Electromagnetically Induced Transparency (EIT) spectroscopy in a room-temperature vapour cell.

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

open access: yesAdvanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Large density amplification measured on jets ejected from a magnetized plasma gun [PDF]

open access: yes, 2007
Observation of a large density amplification in the collimating plasma jet ejected from a coplanar coaxial plasma gun is reported. The jet velocity is ~30 km s^-1 and the electron density increases from ~10^20 to 10^(22–23) m^-3.

Photochromic Cholesteric Liquid Crystals via Arylazopyrazole Functionalization of Hydroxypropyl Cellulose

open access: yesAdvanced Materials, EarlyView.
We produce a new derivative of hydroxypropyl cellulose functionalized with arylazopyrazole side chains and demonstrate its photoswitchable behaviors in dilute and concentrated aqueous solutions, ultimately designing a series of photochromic cholesteric materials that can be photopatterned as write‐erase displays.

Semiclassical Stark Broadening Parameters of Ar VII Spectral Lines

open access: yesAtoms, 2017
Using the semi-classical perturbation approach in the impact approximation, full width at half maximum and shift have been determined for eight spectral lines of Ar VII, for broadening by electron-, proton-, and He III-impacts.

An Atomic‐Level Bimetallic MOF Platform Overcoming the Stability‐Performance Tradeoff for Laser Propulsion

open access: yesAdvanced Materials, EarlyView.
This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...

On the stark broadening of Os II spectral lines [PDF]

open access: yesBulletin of Natural Sciences Research, 2020
Stark broadening parameters, full widths at half maximum (FWHM) and shifts for 13 Os II lines have been calculated. The plasma parameters are: electron density of 1017 cm-3 and temperatures from 5 000 K to 80 000 K.
