An in-site observation station for soils around the ground heat exchanger (GHE) in the operating process of ground source heat pump (GSHP) is installed to monitor the operation performance of GSHP as well as heat and moi...

This paper focuses on control systems for hybrid heat pumps that utilize the heat from return heat-ing water and outdoor air, designed to operate in district heating systems based on central heating plants. The aim of th...

In chilling and/or freezing of foods by hydrofluidization (HF), the liquid refrigerant is pumped through orifices or nozzles, creating agitating jets. The objectives of this work were to design and build a HF system of p...

Geothermal energy pile is the new pile technology that combines the ground source heat pump technology and building pile foundation. Due to the pile as the heat transfer carrier of ground source heat pumps, the bearing c...

Abstract Background The residential building sector is a major contributor to Germany’s greenhouse gas emissions. Over 60 % of the energy used for space and domestic hot water heating comes from fossil fuels sources a...

The Levantine Basin is an ultra-oligotrophic region and the formation site of Levantine Intermediate Water. A high-resolution 3D coupled hydrodynamic-biogeochemical model (SYMPHONIE-Eco3MS) was used to investigate the se...

"Currently, different technologies are being employed to remove CO2 and H2S from the natural gas. Based on chemical phenomenon, the absorption using alkanolamines is probably the most extended process for the acid gas re...

Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resol...

As an exceptional nonlinear material, graphene offers versatile appealing properties, such as electro-optic tunability and high electromagnetic field confinement in the terahertz regime, spurring advance in ultrashort pu...

Abstract Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in many industrial applications. In this paper we propose that an innovative new cla...
