Numerical research on vibration-enhanced heat transfer of improved elastic tube bundle heat exchanger

open access: yesCase Studies in Thermal Engineering, 2022
Based on the traditional elastic tube bundle (ETB) heat exchanger, an improved elastic tube bundle (IETB) heat exchanger with ETB structure upgraded and baffles installed was proposed to study its comprehensive heat transfer performance. The influence of

Numerical study of an exhaust heat recovery system using corrugated tubes and twisted tape inserts [PDF]

open access: yes, 2014
Thesis (M.S.) University of Alaska Fairbanks, 2014Diesel engine generators are the major power source for small communities in cold regions. Diesel generators waste about 1/3 of their fuel energy in the form of heat through exhaust gas.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Performance map of a heat pipe charged with ammonia [PDF]

open access: yes, 1970
Test results are presented which describe dryout in type-304 stainless steel heat pipes when ammonia is the working fluid. Graph compares heat transfer capabilities of both ammonia and water.

Flow maldistribution in industrial air heaters and its effect on heat transfer [PDF]

open access: yes, 2014
Flow maldistribution in cross-flow heat exchangers used for industrial air heaters or recuperators is fairly common and can lead to a number of undesirable effects, one of which is deterioration in the thermal performance.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Heat Transfer Performance of Cosine-Shaped Runners

open access: yes, 2021
Abstract To optimize the heat transfer performance of heat exchangers, this study explored the flow properties and heat transfer of cosine-wave-shaped runners with different structural parameters (wave amplitude, focal distance, and circle radius).

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Improving heat transfer performance in serpentine microchannel with carbon nanotube-embedded PVDF coating

open access: yesCase Studies in Thermal Engineering
This paper examines the impact of a polyvinylidene fluoride (PVDF) and carbon nanotube (CNT) hybrid coating on the heat transfer and hydraulic performance of serpentine microchannel heat sinks.
