Influence of Aluminum Silicate and Cerium (IV) Oxide Nanofluid on Pool Boiling Characteristics

open access: yesInternational Journal of Photoenergy, 2022
A study into pool boiling heat transfer with nanofluids particularly aluminum silicate and cerium (IV) oxide was used to prepare nanofluids. A review of existing nanofluid implementations done previously in multiple literature and research journals was ...

Understanding pool-riffle dynamics through continuous morphological simulations

open access: yes, 2011
Pool-riffle dynamics is governed by complex time and spatial interactions between water and sediment flows. In the last few decades, significant advances have been made in characterizing and modeling the hydrodynamics of pool-riffle sequences, and this ...

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 ...

Nitric oxide and glutathione impact the expression of iron uptake- and iron transport-related genes as well as the content of metals in A. thaliana plants grown under iron deficiency [PDF]

open access: yes, 2012
Mounting evidence indicate that nitric oxide (NO) acts as a signaling molecule mediating iron deficiency responses through the up-regulation of the expression of iron uptake-related genes.

Design and Investigation of a Novel Local Shielding Gas Concept for Laser Metal Deposition with Coaxial Wire Feeding

open access: yesApplied Sciences, 2023
Laser metal deposition with coaxial wire feeding is a directed energy deposition process in which a metal wire is fed to a laser-induced melt pool. Oxidation occurring during the process is a major challenge as it significantly influences the mechanical ...

Signaling from blood vessels to CNS axons through nitric oxide [PDF]

open access: yes, 2006
Brain function is usually perceived as being performed by neurons with the support of glial cells, the network of blood vessels situated nearby serving simply to provide nutrient and to dispose of metabolic waste.
