Drug-biopolymer dispersions: morphology-and temperature-dependent (anti)plasticizer effect of the drug and component-specific Johari–Goldstein relaxations
(2022-03-01)
Article
Open AccessAmorphous molecule-macromolecule mixtures are ubiquitous in polymer technology and are one of the most studied routes for the development of amorphous drug formulations. For these applications it is crucial to understand ... -
Analysis of the anelastic deformation of high-entropy Pd20Pt20Cu20Ni20P20 metallic glass under stress relaxation and recovery
(2022-04-30)
Article
Open AccessThe anelastic deformation behavior of Pd20Pt20Cu20Ni20 P20 high-entropy metallic glass was probed by monitoring the stress relaxation and recovery processes. The stress relaxation under consecutive strain steps can be ... -
Unraveling the microstructural heterogeneity and plasticity of Zr50Cu40Al10bulk metallic glass by nanoindentation
(2022-07-01)
Article
Open AccessUnraveling the microstructural heterogeneity is an important issue to understand the physical and mechanical properties of metallic glasses. Structural relaxation below the glass transition tem- perature Tg and cold ... -
A hierarchically correlated flow defect model for metallic glass: Universal understanding of stress relaxation and creep
(2022-07-01)
Article
Open AccessDue to the structurally disordered arrangement of atoms and deviation from thermodynamic equilibrium, the physical and mechanical properties of metallic glasses can vary with time, temperature and magnitude of strain or ... -
Carbonation of fresco mural paintings with a dolomitic mortar
(2022-07)
Article
Open AccessA fresco painting has a calcium carbonate binder produced as result of the carbonation process of a lime paste. The reaction environmental conditions are similar to those of bio-mineral formation where an amorphous cal-cium ... -
Comprehensive insights into the thermal and mechanical effects of metallic glasses via creep
(2022-02-10)
Article
Open AccessEvolution of deformation and relaxation behaviors of a prototypic metallic glass was explored by extensive creep tests under both physical aging and cyclic loading. Deep insights into the microstructure-induced dynamic ... -
Manganese crystalline phases developed in high lead glazes during firing
(Elsevier, 2022-08-13)
Article
Open AccessA High Temperature Synchrotron Radiation X-Ray Powder Diffraction experiment was performed to determine the manganese compounds formed during the heating and cooling of 70 wt% PbO – 30 wt% SiO2 mixture or the equivalent ... -
An experimental and numerical investigation on fatigue of composite and metal aircraft structures
(2022-04)
Article
Open AccessThe static strength and fatigue crack resistance of the aircraft skin structures depend on the materials used and joint type. Most of the commercial aircraft’s skin panel structures are made from aluminium alloy and carbon ... -

The solid state of anti-inflammatory morniflumate diniflumate: A cocrystalline salt
(2021-12-15)
Article
Open AccessMorniflumate diniflumate, a molecular compound involving niflumic acid and its ß-morpholino ethyl ester (morniflumate) in the mole ratio 2:1, is found to crystallize in a triclinic P - 1 space group with a unit-cell volume ... -
Jun ware glaze colours: An X-ray absorption spectroscopy study
(Elsevier, 2022-06)
Article
Open AccessJun ware is stoneware created in the late Northern Song dynasty (12th century) with a blue glaze combining transparent-blue and whitish-opaque submillimetric areas. The glaze has a glass nanostructure with lime-rich droplets ... -
Enhanced photoproduction of hydrogen on Pd/TiO2 prepared by mechanochemistry
(Elsevier, 2022-07-15)
Article
Open AccessSupported metal clusters are considered as promising cocatalysts in heterogeneous photocatalysis due to their singular geometric structures and unique reactivity. Nevertheless, to explore efficient synthetic routes that ...
