Examining the Impact of Using Hemispherical Dimples-protrusions on Heat Transfer and Pressure Drop in the Finned-tube Heat Exchanger with Different Configurations [PDF]

Journal of Applied Fluid Mechanics
In comparison to a plain fin, the addition of dimples or protrusions to the fins of a finned tube heat exchanger significantly affects the promotion of heat transfer.

Hombre, bienaventuranza y Dios en Suma Teológica l-ll, qq. 1-6.

Tópicos, 2013
This article studies the Aquinas' proposal on Summa Theologica I-II, qq-1-6, where he studies how should the final end of the man be and concludes that it should be transcendental in a certain way, but immanent in another and that God is the immanent end;

The Fish Family Poeciliidae as a Model to Study the Evolution and Diversification of Regenerative Capacity in Vertebrates

Frontiers in Ecology and Evolution, 2021
The capacity of regenerating a new structure after losing an old one is a major challenge in the animal kingdom. Fish have emerged as an interesting model to study regeneration due to their high and diverse regenerative capacity.

Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

Advanced Engineering Materials, EarlyView.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Nature‐Inspired Sustainable Cooling for Photovoltaics with Enhanced Temperature‐Salinity Dynamics

Advanced Functional Materials, EarlyView.
Addressing solar panel overheating, a nature‐inspired cooling system mimicking ocean currents is developed. A moisture‐absorbing solution layer uses sunlight, radiative cooling, and moisture processes to create temperature/salinity gradients, accelerating circulation. The prototype cools panels by up to 18.2 °C under sunlight, sustains cooling, rapidly
