Comparison of measured exhaled nitric oxide at varying flow rates [PDF]

Thorax, 2005
Altered levels of exhaled nitric oxide (FeNO) have been well documented in a number of conditions, although it is in asthma that this phenomenon has been most extensively investigated.1 Raised FeNO levels in patients with asthma have been correlated not only with other markers of airway inflammation (including induced sputum eosinophil count), but also

Material Coupling in Hybrid Neuromorphic Devices: From Fundamentals to System‐Level Applications

Advanced Functional Materials, EarlyView.
Hybrid neuromorphic devices utilize heterointerfaces between emerging semiconductors, where charge transfer and trapping, ion or defect modulation, and photogating are translated into synaptic functions. This paper discusses coupling strategies that tailor interfacial electronic and ionic properties in organic semiconductors, metal oxides, two ...

Experimental study on the radon exhalation characteristics of block walls currently used in China

Nuclear Engineering and Technology
In order to establish a predictive model for indoor radon concentration in Chinese buildings, walls were constructed using Chinese-style bricks to study the relationship between radon exhalation rates and indoor radon concentrations, as well as the ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Modeling of radon exhalation from soil influenced by environmental parameters.

, 2018
Atmospheric radioactive noble gas radon (Rn-222) originates from soil gas exhaled in the atmospheric surface layer. Radon exhalation rates from soil as well as corresponding meteorological and soil parameters were recorded for two subsequent years. Based

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Estimation of global radon exhalation rate distribution [PDF]

A radon exhalation rate distribution model was developed, which considers dependency on soil water saturation, soil temperature and soil texture. The global averages of the radon exhalation rates were calculated to be 17.5 and 18.0 mBq·m^{-2}·s^{-1} by ...

Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

Advanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Study on influence of soil and atmospheric parameters on radon/thoron exhalation rate in the Bangalore University campus, Bengaluru

Radiation Protection and Environment, 2018
In the present study, Radon (222Rn) and Thoron (220Rn) concentration have been measured in the Bangalore University Campus using RAD7 during the postmonsoon season. The results reveal that 222Rn concentration ranged from 360 ± 146 to 643 ± 196 Bq/m3 with
