Heat capacity anomalies of the molecular crystal 1-fluoro-adamantane at low temperatures
(Nature, 2021-09-20)
Article
Open AccessDisorder–disorder phase transitions are rare in nature. Here, we present a comprehensive low-temperature experimental and theoretical study of the heat capacity and vibrational density of states of 1-fluoro-adamantane ... -
Colossal reversible barocaloric effects in layered hybrid perovskite (C10H21NH3)2MnCl4 under low pressure near room temperature
(2021-11-10)
Article
Open AccessBarocaloric effects in a layered hybrid organic–inorganic compound, (C10H21NH3)2MnCl4, that are reversible and colossal under pressure changes below 0.1 GPa are reported. This barocaloric performance originates in a phase ... -
Sensitivity analysis of maximum circulation of wake vortex encountered by en-route aircraft
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-16)
Article
Open AccessWake vortex encounters (WVE) can pose significant hazard for en-route aircraft. We studied the sensitivity of wake vortex (WV) circulation and decay to aircraft mass, altitude, velocity, density, time of catastrophic wake ... -
Uniaxial negative thermal expansion in polymorphic 2-bromobenzophenone, due to aromatic interactions?
(American Chemical Society, 2021-04-07)
Article
Restricted access - publisher's policyThe structure of the metastable form II of 2-bromobenzophenone, obtained by crystallization from the melt, has been determined by powder X-ray diffraction. Form II has been solved in the centrosymmetric monoclinic space ... -
Structure and dynamics of water plastic crystals from computer simulations
(2021-03-14)
Article
Restricted access - publisher's policyWater has a rich phase diagram with several crystals, as confirmed by experiments. High-pressure and high-temperature water is of interest for Earth’s mantle and exoplanetary investigations. It is in this region of the ... -
Investigation of the mechanical properties and biocompatibility of planar and electrospun alkene-styrene copolymers against P(VDF-TrFE) and porcine skin: Potential use as second skin substrates
(Elsevier, 2021-07-01)
Article
Restricted access - publisher's policyElastomers have been used in a variety of biomedical fields, including tissue engineering, soft robotics, prostheses, and cosmetics. Elastomers used for skin grafting scaffolds tend to be biodegradable, but other applications ... -
Identifying the high entropy characteristic in La-based metallic glasses
(2021-08-05)
Article
Open AccessHigh temperature deformation was probed in a La-based high entropy metallic glass with an evident slow ß relaxation. The correlation between high configurational entropy and high temperature deformation mechanism was ... -
Polymorphism of benzylthiouracil, an active pharmaceutical ingredient against hyperthyroidism
(2021-04-01)
Article
Restricted access - publisher's policyThe crystal structures of dimorphic benzylthiouracil, a drug against hyperthyroidism, have been redetermined and the atom coordinates of the two independent molecules of form I have been obtained for the first time. The ... -
Comparative physical study of three pharmaceutically active benzodiazepine derivatives: crystalline versus amorphous state and crystallization tendency
(American Chemical Society, 2021-01-01)
Article
Restricted access - publisher's policyChemical derivatization and amorphization are two possible strategies to improve the solubility and bioavailability of drugs, which is a key issue for the pharmaceutical industry. In this contribution, we explore whether ... -
Crystalline tetrazepam as a case study on the volume change on melting of molecular organic compounds
(2021-01-25)
Article
Restricted access - publisher's policyThe volume change on melting is a rarely studied quantity and it is not well understood even if it must reflect the changes in interaction between the solid and the liquid state. It is part of the solid-state information ... -
Evaluation of the Effect of Minor Additions in the Crystallization Path of [(Fe0.5Co0.5)0.75B0.2Si0.05]100-xMx Metallic Glasses by Means of Mössbauer Spectroscopy
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-16)
Article
Open AccessUnderstanding the crystallization of metallic glasses is fundamental in the design of new alloys with enhanced properties and better glass-formability. The crystallization of a series of Fe-based metallic glasses of ... -
Stress relaxation in high-entropy Pd20Pt20Cu20Ni20P20 metallic glass: experiments, modeling and theory
(2021-09-01)
Article
Restricted access - publisher's policyThe viscoelastic properties of Pd20Pt20Cu20Ni20P20 high-entropy metallic glass were probed by dynamic mechanical spectroscopy and stress relaxation. The experimental evolution of stress can be characterized by the empirical ...
