Performance of natural, exhaust, demand controlled exhaust and heat recovery residential ventilation systems as prescribed by the standards in 5 European countries [PDF]

open access: yes, 2013
Over the last decades, residential ventilation standards have been integrated in most of the buildings codes of European countries. Contrarily to the consolidation effort in the development of the nonresidential ventilation standard EN 13779, most of the

Decoupling Transport of Salt Ions and Water in Hierarchically Structured Hydrogel for High Salinity Desalination

open access: yesAdvanced Materials, EarlyView.
A hierarchically structured hydrogel evaporator enables controlled decoupling of salt‐ion and water transport pathways for efficient solar desalination in hypersaline environments. Engineered radial and vertical channels direct salt away from the evaporative interface, enhancing water evaporation and ambient energy harvesting via a cold‐surface effect.

Particularities of determining primary energy needs for building materials/Pirminės energijos poreikių statybinėms medžiagoms nustatymo ypatumai

open access: yesJournal of Civil Engineering and Management, 1997
Civil buildings in Lithuania consume one half of final energy or about 70% of heat generated in thermoelectric and heat power stations. However, energy is necessary not only for exploitation but also for the creation of buildings: manufacture of building

Light‐Activated Micromotors in Air Propelled by Thermal Convection

open access: yesAdvanced Materials, EarlyView.
Near‐infrared‐driven micromotors in air can overcome gravity and generate convective motion by a light‐induced thermal mechanism driven by a temperature gradient in the air caused by the interaction of the gold nanoparticles present on the surface of ZnO and NIR irradiation.

Passive house ventilation strategies: demand control? [PDF]

open access: yes, 2009
Since insulation levels in a passive house context are very high, energy losses trough ventilation are of relatively high importance in the total energy balance of a passive house concept.

Regularity of Respiratory Waveform Depends on Ventilation Parameters [PDF]

open access: yes, 2020
Entropy is a nonlinear method for quantifying the regularity and order of a system. Entropy was originally born from thermodynamics and is now used in various fields, such as statistical mechanics and information ethics.

Triggering of the Ventilator in Patient-Ventilator Interactions [PDF]

open access: yesRespiratory Care, 2011
With current ventilator triggering design, in initiating ventilator breaths patient effort is only a small fraction of the total effort expended to overcome the inspiratory load. Similarly, advances in ventilator pressure or flow delivery and inspiratory flow termination improve patient effort or inspiratory muscle work during mechanical ventilation ...

Development of 3D Reversible Smart Energy‐Saving Devices for Adaptive Energy Management

open access: yesAdvanced Materials, Volume 37, Issue 43, October 29, 2025.
Smart energy‐saving devices with 3D structures operate passively and exhibit reversible solar heating and radiative cooling functions. These devices demonstrate superior performance in building thermal management through dual‐mode operation and provide an optimized 3D energy management platform applicable across various angular environments.
