Generation of energetic He atom beams by a pulsed positive corona discharge [PDF]

open access: yes, 1997
Time-of-flight measurements were made of neutral helium atom beams extracted from a repetitive, pulsed, positive-point corona discharge. Two strong neutral peaks, one fast and one slow, were observed, accompanied by a prompt photon peak and a fast ion ...

Tri‐Layered Bioactive Cutaneous Scaffold with Integrated Bioactive Metal Organic Frameworks to Promote Full‐Thickness Infected Diabetic Wound Healing: Multifaceted Therapeutic Strategies

open access: yesAdvanced Healthcare Materials, EarlyView.
The limitations of existing clinical treatments highlight the need for a more comprehensive strategy for addressing infected diabetic wounds. A tri‐layered scaffold is developed to deliver therapeutics loaded in CuBDC and ZIF‐8 MOFs that are tailored to the requirements of deep‐infected diabetic wounds.

Hot Gas Flows on Parsec Scale in the Low-Luminosity Active Galactic Nucleus NGC 3115 [PDF]

open access: yes, 2019
NGC 3115 is known as the low-luminosity active galactic nucleus which hosts the nearest ($z\sim0.002$) billion solar mass supermassive black hole ($\sim1.5\times10^9~M_\odot$). Its Bondi radius $r_\mathrm{B}$ ($\sim3\farcs6$) can be readily resolved with Chandra, which offers us an excellent opportunity to investigate the accretion flow onto a ...

Long-lead forecasts of wintertime air stagnation index in southern China using oceanic memory effects [PDF]

open access: yesarXiv, 2023
Stagnant weather condition is one of the major contributors to air pollution as it is favorable for the formation and accumulation of pollutants. To measure the atmosphere's ability to dilute air pollutants, Air Stagnation Index (ASI) has been introduced as an important meteorological index.

The thermochemical non-equilibrium scale effects of the high enthalpy nozzle

open access: yesAdvances in Aerodynamics, 2020
The high enthalpy nozzle converts the high enthalpy stagnation gas into the hypervelocity free flow. The flow region of the high enthalpy nozzle consists of three parts: an equilibrium region upstream of the throat, a non-equilibrium region near the ...
