Solar‐Driven Atmospheric Water Production Through Hierarchically Ordered Porous Carbon for Self‐Sustaining Green Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
Green hydrogen production through a coupled self‐sustaining solar‐enabled system that couples atmospheric water harvesting with PEM water electrolysis (AWH‐PEMWE), offering a novel pathway for clean water generation and green hydrogen production. The system operates without the need for carrier gases or external energy input accessories, enabling a ...

Does tidal volume challenge improve the feasibility of pulse pressure variation in patients mechanically ventilated at low tidal volumes? A systematic review and meta-analysis

open access: yesCritical Care, 2023
Background Pulse pressure variation (PPV) has been widely used in hemodynamic assessment. Nevertheless, PPV is limited in low tidal volume ventilation. We conducted this systematic review and meta-analysis to evaluate whether the tidal volume challenge ...

Results from the Search for Tidal Disruption Flares in the GALEX Deep Imaging Survey [PDF]

open access: yes, 2007
A supermassive black hole in the nucleus of a galaxy will be revealed when a star passes close enough to be torn apart by tidal forces and a UV/X-ray flare is emitted by the stream of stellar debris that plunges into the black hole.

Some mechanisms of "spontaneous" polarization of superfluid He-4

open access: yes, 2010
Previously, a quantum "tidal" mechanism of polarization of the atoms of He-II was proposed, according to which, as a result of interatomic interaction, each atom of He-II acquires small fluctuating dipole and multipole moments, oriented chaotically on ...

Unveiling Ultrafast Spin‐Valley Dynamics and Phonon‐Mediated Charge Transfer in MoSe2/WSe2 Heterostructures

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...

Current ventilation practice during general anaesthesia: a retrospective audit in Melbourne, Australia

open access: yesBMC Anesthesiology, 2014
Background Recent evidence suggests that the use of low tidal volume ventilation with the application of positive end-expiratory pressure (PEEP) may benefit patients at risk of respiratory complications during general anaesthesia.

Effects of Back Touching on Tidal Volume [PDF]

open access: yesPsych, 2019
The purpose of this basic experiment was to examine the effects of soft touching on an experiment participant’s back on tidal volume (TV), as an increase in TV was considered an indication of enhanced relaxation. Healthy experiment participants were divided into an intervention group, where soft touching was administered for two minutes on their back ...

Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, EarlyView.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

Changes in Diaphragmatic Function Induced by an Increased Inspiratory Load Experienced by Military Divers: An Ultrasound Study

open access: yesFrontiers in Physiology, 2021
Background: Inspiratory loading is experienced by military divers when they use rebreather device. Our objective was to assess the changes in diaphragm function induced by an increase in inspiratory load at values similar to those experienced by divers ...

Engineering Neutrophil Vesicles for Synergistic Protection against Ischemia/Reperfusion Injury after Lung Transplant

open access: yesAdvanced Science, EarlyView.
Engineered neutrophil‐derived vesicles (SOD2‐Fer‐1@CVs) co‐delivering antioxidant and ferroptosis‐inhibitory agents enable inflammation‐targeted, ROS‐responsive therapy for ischemia–reperfusion injury in lung transplantation. Synergizing with ex vivo lung perfusion, this strategy alleviates oxidative stress and inflammation, restores vascular integrity,
