Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Using corrugated tubes in external molten salt receivers [PDF]

AIP Conference Proceedings, 2019
CFD models have been used to show the potential of using corrugated tubes instead of smooth tubes at a solar thermal receiver using molten salt as heat transfer fluid. The results were compared on the basis of a 700 MWth receiver. Absorber tubes with an inner diameter between 32.8mm and 70 mm using a helical ribbed structure have been analyzed.

The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.

Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

European Journal of Inorganic Chemistry, EarlyView.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...

Unexpected crossover dynamics of single polymer in a corrugated tube [PDF]

The Journal of Chemical Physics, 2012
We present molecular dynamics study of a generic (coarse-grained) model for single-polymer diffusion confined in a corrugated cylinder. For a narrow tube, i.e., diameter of the cylinder δ < 2.3, the axial diffusion coefficient D|| scales as D|| ∝ N−3/2, with chain length N, up to N ≈ 100 and then crosses over to Rouse scaling for the larger N ...

A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.

CFD Analysis of Heat Transfer Enhancement for Twisted Tape Inserted in Spirally Corrugated Tubes and Proposal of a New Vane-Inserted Geometry

Fluids
This research investigates the enhancement of heat transfer in a heat exchanger that is made of a corrugated tube which has a twisted plate inserted in it; the corrugation and twisted plate are expected to increase the amount of heat transfer since the ...

Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

Energy Science &Engineering, EarlyView.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.
