VO2(B), as one of metastable phases of vanadium dioxide, have stimulated great interest due to their layered structure, novel chemical and physical properties, and a wide variety of potential applications, including catalysis, cathode materials for reversible lithium batteries, temperature-sensing devices, optical switching devices, optical data-storage media, etc [3, 4].
Some traditional methods such as thermal reduction of V2O5 by H2 or SO2 gas, heating VO2 powders at high temperature in an argon atmosphere have been reported, which lead to bulk VO2.

For metals, engineering data such as yield strength, tensile strength, modulus of elasticity and ductility are generally obtained.
The reduction in area describes the amount of thinning that the specimen undergoes during the test.

The cross-section for the data illustration is placed through the highest point of the sample after the first pulse.
On the one hand the optimal counterpunch can be characterized by a sufficient reduction of rejects.

All data were presented as mean ± standard deviation of n independent observations.
Respiration causes a weight reduction because a carbon compound in gas (mainly ethylene) is lost from the fruit in each cycle [11].

Proper selection can lead to substantial savings in machining time, improvement of workpiece surface quality and improvement in tool life, thereby leading to overall cost reduction and higher productivity [6].
M.Weck and Y.Altintas [9] integrated chatter limit data and tool paths generation together.

The addition of small amounts of zirconium leads to a drastic reduction of the growth velocity, compared to the pure metal, at undercoolings less than a critical undercooling ∆Tc.
But a comparison of both data sets yield the important result that the critical undercooling ∆Tcrit for the onset of primarily formed metastable bcc phase is decreased from about 90 K on Earth to 53 K in reduced gravity.

The Scherrer equation was used to calculate the crystallite size of the GDC nano particles from the XRD data.
This de-densification phenomenon results from the reduction of Ce 4+ ions to Ce 3+ ions at temperatures over 1200 oC.[9] On the other hand, water dispersed GDC nano particles started to shrink at 1000 oC and reached near full density at 1400 oC while showing no de-densification throughout the experimental temperature range.

The effectiveness of the buttering on the extent of reduction in the residual stress in dissimilar weldments between 2.25Cr-1Mo ferritic steel and 316L austenitic stainless steel has been thoroughly studied [1], however, its implications on the microstructure and mechanical properties of the weldments were not considered.
The profiles were plotted using EDS spot analysis data which were individually obtained at 0.5 mm intervals along a horizontal line extending from the ferritic base metal side up to the weld centreline at the middle of the weld joint.

The experimental data were analyzed and load–deflection curves were generated.
The reduction in stiffness with temperature was more important for the FRP composite decks than for the reinforced-concrete deck and the FRP-concrete deck.

The decenter adjustments of each edge segment are shown to provide an important additional correction mechanism for further reduction of tolerance stringency.
Fabrication errors on the shape parameters of the segments can be input, and the measured data can be given via interferogram files.
