The kinetic glass transition

open access: yes, 2000
Kinetic lattice-gas models display fragile-glass behaviour, in spite of their trivial Gibbs-Boltzmann measure. This suggests that the nature of glass transition might be, at least in some cases, understood in purely kinetic or dynamical ...

Coamorphous Systems of Valsartan: Thermal Analysis Contribution to Evaluate Intermolecular Interactions Effects on the Structural Relaxation

open access: yesMolecules, 2023
Coamorphous formation in binary systems of valsartan (Val) with 4,4′-bipyridine (Bipy) and trimethoprim (Tri) was investigated for mixtures with a mole fraction of 0.16~0.86 of valsartan and evaluated in terms of the glass transition temperature.

Simulation procedures for glass transition temperatures and thermal expansion coefficients of BaO-B2O3 glasses

open access: yes, 2016
In order to reflect the so-called boron anomaly, three types of B-O structural units, namely, BO3/2, BO4/2- and BO2/2O-, were considered for the BaO-B2O3 glass.

Optical Properties of Nd3+ Doped Phosphate Glasses at 4F3/2 -> 4I11/2 Hypersensitive Transitions [PDF]

open access: yesJournal of Pure and Applied Chemistry Research, 2016
The lasing transition 4F3/2®4I11/2 for Nd3+ doped phosphate glass centered around 1.05 – 1.07mm is referred as hypersensitive transition. The radiative properties such as effective linewidth (Dleff), radiative transition probability (AR), branching ratio

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Kinetically controlled glass transition measurement of organic aerosol thin films using broadband dielectric spectroscopy [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Glass transitions from liquid to semi-solid and solid phase states have important implications for reactivity, growth, and cloud-forming (cloud condensation nuclei and ice nucleation) capabilities of secondary organic aerosols (SOAs).

Effects of Annealing on Enthalpy Recovery and Nanomechanical Behaviors of a La-Based Bulk Metallic Glass

open access: yesMetals, 2021
Structural relaxation and nanomechanical behaviors of La65Al14Ni5Co5Cu9.2Ag1.8 bulk metallic glass (BMG) with a low glass transition temperature during annealing have been investigated by calorimetry and nanoindentation measurement.

The glass transition and the Jarzynski equality [PDF]

open access: yesThe Journal of Chemical Physics, 2008
A simple model featuring a double well potential is used to represent a liquid that is quenched from an ergodic state into a history-dependent glassy state. Issues surrounding the application of the Jarzynski equality to glass formation are investigated.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Inhibition of dipeptidyl peptidase 7 impairs lysophagy in LLOMe‐treated HepG2 cells

open access: yesFEBS Letters, EarlyView.
DPP7 inhibition delays ubiquitin‐dependent lysophagy by attenuating ubiquitin accumulation and the recruitment of SQSTM1 and LC3 to damaged lysosomes, resulting in delayed clearance of damaged lysosomes and impaired restoration of lysosomal homeostasis. Created using FigureLabs (Certificate ID: FL‐PUB‐20260922‐Z99XNX).
