Integration of space heating and hot water supply in low temperature district heating [PDF]
Energy and Buildings, 2016 Abstract District heating may supply many consumers efficiently, but the heat loss from the pipes to the ground is a challenge. The heat loss may be lowered by decreasing the network temperatures for which reason low temperature networks are proposed for future district heating. The heating demand of the consumers involves both domestic hot water and

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

UPDATED HEAT BALANCE OF SUPPLIED HEAT ENERGY BY THE DISTRICT HEATING SYSTEM
Energy Technologies & Resource SavingDistrict heating systems are significant energy consumers in Ukraine and globally. The current regulatory documents in Ukraine that define the methodology for calculating the heat balance of a district heating system and the value of standard heat losses do not take into account some hidden heat losses that affect the prospects for economic growth of ...

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling
Advanced Engineering Materials, EarlyView.Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Locating the Temperature Switch for a Drag Reducing Solution [PDF]
, 2018 Low-cost and environmentally friendly district heating has become a popular trend in northern Europe. These systems use excess heat from plants or factories to heat water, which is then used to supply heat to homes and buildings in the surrounding area ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
