Material Transport Characteristics in Planetary Roller Melt Granulation

open access: yesPharmaceutics, 2023
Melt granulation for improving material handling by modifying particle size distribution offers significant advantages compared to the standard methods of dry and wet granulation in dust reduction, obviating a subsequent drying step. Furthermore, current

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Onset velocity of circulating fluidization and particle residence time distribution: A CFD-DEM study

open access: yes, 2015
Until now, the onset velocity of circulating fluidization in liquid-solid fluidized beds has been defined by the turning point of the time required to empty a bed of particles as a function of the superficial liquid velocity, and is reported to be only

An attainable region perspective on the role of residence time distribution in ball milling

open access: yesSouth African Journal of Chemical Engineering, 2020
The effect of material flow through a ball mill on the efficient production of particles was explored using the attainable region framework. The target efficiency was the production of floatable particles of size between 300 μm and 75 μm upon expending ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Residence time distribution

open access: yes, 2020
U ovom radu istraživala se raspodjela vremena zadržavanja (RVZ) u tri različite cijevi, ravnoj cijevi, cijevi sa staklenim kuglicama te spiralnoj cijevi koje opisuju hidrodinamiku strujanja u različitim tipovima cijevnih reaktora.

An improved model of continuous leaching systems using segregation approach [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2020
In this study, a simplified dissolution model has been developed to evaluate the performance of continuous leaching reactors. The model considers continuous reduction of the surface area of particles using the distribution of their size and residence ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

The Influence of Residence Time Distribution on Continuous-Flow Polymerization

open access: yes, 2019
Continuous-flow chemistry is emerging as an enabling technology for the synthesis of precise polymers. Recent advances in this rapidly growing field have hastened a need for a fundamental understanding of how fluid dynamics in tubular reactors influence ...
