Influence of Cryogenic Treatments on the Wear Behavior of AISI 420 Martensitic Stainless Steel
(Springer, 2017-11)
The objective of the present work is to characterize the wear behavior of a cryogenically treated low-carbon AISI 420 martensitic stainless steel, by means of ball-on-disk tribological tests. Wear tests were performed under ...
Light induced reactions in cryogenic matrices
(Royal Society of Chemistry, 2010)
This chapter centers on the topic of light induced reactions in cryogenic matrices, ranging from conformational isomerizations to complex bond-breaking/bond-forming processes. Recent progress in the photoinduced chemistry ...
Rolling Contact Fatigue Resistance of Cryogenically Treated AISI 440C Steel
(Springer, 2020-04-20)
AISI 440C is a high carbon martensitic stainless steel, primarily used in bearing applications. For this study, one group of AISI 440C steel disks was quenched in oil and tempered. Another group was soaked in liquid nitrogen ...
Dynamic Modelling and Optimisation of Large-Scale Cryogenic Separation Processes
(Italian Association of Chemical Engineering, 2005-06)
In this work, the open loop dynamic optimisation of a large-scale natural gas processing plant is performed. A rigorous differential-algebraic equation (DAE) model has been formulated to represent main plant units, such ...

QUBIC V: Cryogenic system design and performance
(IOP Publishing, 2021-10)
Current experiments aimed at measuring the polarization of the Cosmic Microwave Background (CMB) use cryogenic detector arrays with cold optical systems to boost their mapping speed. For this reason, large volume cryogenic ...
Cryogenic landforms in the Sierras de Alvear, Fuegian Andes, subantarctic Argentina
(John Wiley & Sons Ltd, 2006-11)
A preliminary survey of periglacial landforms found in the Monte Alvear region of the Fuegian Andes, subantarctic Argentina has revealed the presence of nivation hollows, subnival 'boulder' (clast) pavements, protalus ...
Molecular structure, infrared spectra, and photochemistry of isoniazid under cryogenic conditions
(American Chemical Society, 2009-07)
In this study, the structure, spectroscopy, and photochemistry of isoniazid (C6H7N3O, INH) were studied by low-temperature infrared spectroscopy and quantum chemistry calculations. According to DFT(B3LYP)/6-311++G(d,p) ...
Light induced reactions in cryogenic matrices (highlights 2011–2012)
(Royal Society of Chemistry, 2013)
In this chapter, relevant studies published in 2011 and 2012 and focusing on the subject of light induced reactions in cryogenic matrices are reviewed. These studies range from conformational isomerizations to complex ...
