We describe a new photonics procedure developed for non-destructive testing of additive manufactured (AM) parts and present a case study for inspection of AM brackets to detect and reject parts containing printing defects. This is an update of a prev

While material parameters are fairly well known for conventional solids, more variability occurs with materials produced by additive manufacturing. A method is described to determine these parameters from the unique vibrational resonanceresponse spec

The use of additively manufactured metal parts has increased dramatically in the past few years. This has drawn considerable attention to the as-built mechanical properties of these parts and their ultimate durability. Additive manufactured parts hav

The paper describes and demonstrates a non-destructive evaluation method that can perform in space, in situ, and postproduction inspection for metallic and non-metallic products of additive manufacturing. The method, which is based upon measuring the

Every object possesses a unique acoustical spectrum/signature that is determined by its dimensions, materials, defects, and history. The signature can be read and analyzed by exciting the part and scanning the surface using Laser Doppler Velocimetry

A lysine instead of the usual carboxyl group is in place of the internal proton donor to the retinal Schiff base in the light-driven proton pump of Exiguobacterium sibiricum (ESR). The involvement of this lysine in proton transfer is indicated by the

The photocycle of the retinal protein from Exiguobacterium sibiricum, which differs from bacteriorhodopsin in both its primary donor and acceptor, is characterized by visible and infrared spectroscopy. At pH above pKa ~6.5, we find a bacteriorhodopsi

Low-temperature FTIR spectroscopy of bacteriorhodopsin and xanthorhodopsin was used to elucidate the number of K-like bathochromic states, their sequence, and their contributions to the photoequilibrium mixtures created by illumination at 80-180 K. W

Below 195 K, the bacteriorhodopsin photocycle could not be adequately described with exponential kinetics [Dioumaev, A. K., and Lanyi, J. K. (2007) Proc. Natl. Acad. Sci. U.S.A. 104, 9621-9626] but required distributed kinetics, previously found in h
