Effect of temperature and radial displacement cycles on soil?concrete interface properties using modified thermal borehole shear test
(
American Society of Civil Engineers (ASCE)
, 2018 , Article)
Thermoactive geostructures (such as energy piles) are used for heating and cooling of buildings, which generate daily temperature changes and cycles in the geostructure and surrounding soil due to the intermittent operation ...
Axial pull-out response of a small-scale concrete pile subjected to cyclic thermal loading in sand
(
American Society of Civil Engineers (ASCE)
, 2018 , Conference Paper)
Energy piles support structural loads and exchange heat with surrounding soils using closed-loop ground source heat pump (GSHP) systems. A GSHP connected to an energy pile operates in cycles where it functions for a period ...
Cyclic loading effects on soil-energy pile interaction
(
CRC Press/Balkema
, 2016 , Conference Paper)
To reduce greenhouse gas emission from space heating and cooling, energy piles have been used in buildings as an alternative renewable energy source for approximate by two decades. However, the effects of cyclic thermal ...

Rheological and controlled release properties of hydrogels based on mushroom hyperbranched polysaccharide and xanthan gum
(
Elsevier B.V.
, 2018 , Article)
A hyperbranched polysaccharide, coded as TM3a, was extracted from the Pleurotus tuber-regium sclerotia. TM3a was hybridized with xanthan gum (XG) by chemical crosslinking using sodium trimetaphosphate (STMP) to obtain new ...
