Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

open access: yesHeat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Parametrical optimization of laser surface alloyed NiTi shape memory alloy with Co and Nb by the Taguchi method [PDF]

open access: yes, 2009
Different high-purity metal powders were successfully alloyed on to a nickel titanium (NiTi) shape memory alloy (SMA) with a 3 kW carbon dioxide (CO2) laser system. In order to produce an alloyed layer with complete penetration and acceptable composition

Biofilm removal capacity and titanium surface integrity in non‐abrasive versus abrasive peri‐implantitis cleaning interventions

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Current peri‐implantitis treatment methods are modeled after dental cleaning modalities like abrasive surface cleaning. However, mechanical abrasive cleaning not only inadequately removes implant biofilms but also compromises implant surface integrity with adverse biological effects.
