Alloy Solutions for Ammonia Cracking: A Review
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

ABSTRACT In the present study, creep tests of a TiAl alloy were conducted using miniature specimens (d = 2 mm) under various conditions to investigate their creep properties at 760°C. The test results indicate that creep rupture time obtained using miniature specimens at identical applied stress levels increase with the order of test condition Ar gas ...

Abstract Monitoring of fluid parameters during well development, groundwater production, or geothermal operation is essential for the understanding of subsurface and well processes. We developed FluMoMax, a portable fluid monitoring unit, that can measure several physicochemical parameters in real‐time, to monitor fluid characteristics and to enable ...

Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.

Control of welding residual stress for dissimilar laser welded materials [PDF]
The most common problem of welding dissimilar metals (DMWs) with respect to residual stresses is the differences in the coefficient of thermal expansion and heat conductivity of the two welded metals.

A flow through cell arrangement was used to examine the oxide formation at copper–copper sulfide interface in an anoxic, sulfide environment. Oxide formation on surface occurs because of exposure to aerated water during sample preparation. On‐line sulfide detection based on the linear polarization resistance of copper is also presented.

Zinc Element Traces to Inhibit Scale Formation on Cooling Tower and Air Cooler Systems
Calcium carbonate is predominantly present in aqueous systems, which is commonly used in industrial processes. It has inverse solubility characteristics resulting in the deposition of scale on heat transfer surface.

Fibrin association at hybrid biointerfaces made of clot-binding peptides and polythiophene [PDF]
The properties as biointerfaces of electroactive conducting polymer-peptide biocomposites formed by poly(3,4-ethylenedioxythiophene) (PEDOT) and CREKA or CR(NMe)EKA peptide sequences (where Glu has been replaced by N-methyl-Glu in the latter) have been ...
