Crystal/glass phase change in KSb5S8 studied through thermal analysis techniques

Chrissafis, K.; Kyratsi, Theodora; Paraskevopoulos, K. M.; Kanatzidis, M. G. (2004)

The reversible crystal-glass and glass-crystal transitions discovered in KSb5S8 were studied in detail with nonisothermal scanning calorimetry techniques. When cooled, molten KSb5S8 becomes a metastable glass, which can ...

A structural, kinetic model of soft tissue thermomechanics

Barocas, V. Η; Stylianopoulos, T.; Aksan, A. (2008)

A structure-based kinetic model was developed to predict the thermomechanical response of collagenous soft tissues. The collagen fibril was represented as an ensemble of molecular arrays with cross-links connecting the ...

A study of volatile organic compounds evolved in urban waste disposal bins

Statheropoulos, Miltiades K.; Agapiou, Agapios; Pallis, George C. (2005)

Volatile organic compounds (VOCs) evolved in urban waste disposal bins in different situations were studied. Waste of various loads (full, empty, partially filled bins), remained uncollected in the containers for variable ...
