Application of fast scanning calorimetry to the fusion thermochemistry of low-molecular-weight organic compounds: Fast-crystallizing m-terphenyl heat capacities in a deeply supercooled liquid state

Yagofarov M.; Lapuk S.; Mukhametzyanov T.; Ziganshin M.; Schick C.; Solomonov B. (2018)

© 2018 Elsevier B.V. Fusion enthalpy temperature dependence is related to the difference in heat capacity of the liquid and solid. Below the melting temperature, it is hard to measure the liquid heat capacity using ...
Kinetic stability of amorphous solid dispersions with high content of the drug: A fast scanning calorimetry investigation

Lapuk S.; Zubaidullina L.; Ziganshin M.; Mukhametzyanov T.; Schick C.; Gerasimov A. (2019)

© 2019 Elsevier B.V. Formation of amorphous solid dispersions is an effective way to enhance the bioavailability of drugs. One of the main disadvantages of such systems is their low storage stability. Estimation and ...
Prototyping of Ultrasonic Die for Extrusion of Ceramic Brick

Kabirov R.; Garipov L.; Faseeva G.; Nafikov R.; Lapuk S.; Zakharov Y. (2017)

© 2017, Springer Science+Business Media, LLC. A scaled-down prototype of a die for extruding ceramic brick with ultrasonic oscillations from a magneto-striction transducer delivered onto the die wall was tested. Extruder ...
The fusion thermochemistry of self-associated aromatic compounds at 298.15 K studied by solution calorimetry

Yagofarov M.; Lapuk S.; Mukhametzyanov T.; Ziganshin M.; Valiakhmetov T.; Solomonov B. (2019)

© 2019 Elsevier Ltd The solution calorimetry approach for determination of the fusion enthalpy at 298.15 K of aromatic compounds not capable of self-association was extended to those forming intermolecular hydrogen bonds. ...
Thermochemical properties of 1,2,3,4-tetraphenylnaphthalene and 1,3,5-triphenylbenzene in crystalline and liquid states studied by solution and fast scanning calorimetry

Yagofarov M.; Lapuk S.; Mukhametzyanov T.; Ziganshin M.; Schick C.; Solomonov B. (2019)

© 2019 Elsevier B.V. Significant deviations were found between the solution enthalpy in benzene at 298.15 K and the fusion enthalpy at the melting temperature of 1,2,3,4-tetraphenylnaphthalene (3.9 ± 0.5 kJ mol −1 and ...
Ultrasound-assisted extrusion of construction ceramic samples

Faseeva G.; Nafikov R.; Lapuk S.; Zakharov Y.; Novik A.; Vjuginova A.; Kabirov R.; Garipov L. (2017)

© 2017 Elsevier Ltd and Techna Group S.r.l.The conditions for a decrease in friction during ceramic brick production between a mixture and an extruder die under the influence of 20–30 kHz ultrasound applied to the die are ...
