Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Investigation of Low-temperature Solders for Cryogenic Wind Tunnel Models [PDF]
, 1985 The advent of high Reynolds number cryogenic wind tunnels has forced alteration of manufacturing and assembly techniques and eliminated usage of many materials associated with conventional wind tunnel models.

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Observations on some transonic wind tunnel test results of a standard model with a T-tail [PDF]
Scientific Technical Review, 2016 As a part of a periodic health monitoring of the wind tunnel structure, instrumentation and flow quality, a series of tests of an AGARD-C calibration model was performed in the 1.5 m T-38 trisonic wind tunnel of the Military Technical Institute (VTI) in ...

Advanced Functional Materials, EarlyView.Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Journal of the Visualization Society of Japan, 1995 Wind tunnel testing in general is described for those who are not familiar with this field of engineering. Wind tunnels are grouped according to the testing speeds, test section geometry and configurations, and tunnel circuit shapes. Similality laws of and problems in wind tunnel testings are presented.
