Influence of Salts on the Adsorption of Lysozyme on a Mixed-Mode Resin

open access: yesAdsorption Science & Technology, 2021
Mixed-mode chromatography (MMC), which combines features of ion exchange chromatography (IEC) and hydrophobic interaction chromatography (HIC), is an interesting method for protein separation and purification.

Coherence and measurement in quantum thermodynamics [PDF]

open access: yesScientific Reports 6, 22174 (2016), 2015
Thermodynamics is a highly successful macroscopic theory widely used across the natural sciences and for the construction of everyday devices, from car engines and fridges to power plants and solar cells. With thermodynamics predating quantum theory, research now aims to uncover the thermodynamic laws that govern finite size systems which may in ...

Hawking radiation as tunneling and the unified first law of thermodynamics at the apparent horizon in the FRW universe

open access: yes, 2009
Relations between the tunneling rate and the unified first law of thermodynamics at the apparent horizon of the FRW universe are investigated. The tunneling rate arises as a consequence of the unified first law of thermodynamics in such a dynamical ...

On phantom thermodynamics [PDF]

open access: yesPhysics Letters B, 2008
The thermodynamic properties of dark energy fluids described by an equation of state parameter $ =p/ $ are rediscussed in the context of FRW type geometries. Contrarily to previous claims, it is argued here that the phantom regime $ 0$ and $S>0$ in the course of the Universe expansion.

A Novel Approach on Rapid Alloy Development of Tool Steels for Laser Powder Bed Fusion by In Situ Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.

Leidenfrost droplet trampolining

open access: yesNature Communications, 2021
The classic Leidenfrost phenomenon is familiar, yet its physics is rather complex. Graeber et al. observe the unexpected development of repeated hopping of a droplet trampolining on its own vapor cushion on a hot plate and show under which conditions ...

Bond Graphs Unify Stoichiometric Analysis and Thermodynamics [PDF]

open access: yesarXiv, 2020
Whole-cell modelling is constrained by the laws of nature in general and the laws of thermodynamics in particular. This paper shows how one prolific source of information, stoichiometric models of biomolecular systems, can be integrated with thermodynamic principles using the bond graph approach to network thermodynamics.

Thermodynamic properties of modified gravity theories

open access: yes, 2016
We review thermodynamic properties of modified gravity theories such as $F(R)$ gravity and $f(T)$ gravity, where $R$ is the scalar curvature and $T$ is the torsion scalar in teleparallelism. In particular, we explore the equivalence between the equations
