The heat affected zone (HAZ) of conventional welding techniques is too wide to weld the high silicon aluminum alloy, as wide HAZ will improve risk of cracking. Laser welding with narrow HAZ, high ...

Abstract: We present long-wavelength InGaAlAs-InP vertical-cavity surface-emitting lasers (VCSELs) with a buried tunnel junction (BTJ) and a well-defined polarization ...

Silver nanoparticles grown in nanochannels of anodic aluminum oxide on a grating form a surface-enhanced Raman scattering (SERS) substrate with the double resonance from both localized and delocalized ...

The emission spectra for control VCSELs with grating DCs of 0% and 100% are shown together with that for an HCG-VCSEL in Fig. 4. A DC of 0% corresponds to having no HCG layer, and a DC of 100% ...

Abstract: A new long-period fiber grating structure based on a tapered fiber side contacted with a metal grating is proposed and demonstrated in this paper. The temperature/index tuning sensitivity ...

Dylan Thiele, a 20-year-old organist and member of the Red River Theater Organ Society, plays the Wurlitzer that once sat in MSUM's Weld Hall for decades. Thiele now owns it and has it in his ...

U.S. Treasury Secretary Scott Bessent responded "who cares?" to news that the U.S. had lost its last top-notch credit rating. Bond markets might beg to differ. In today's deep dive, I discuss why ...

In this study, we show how to use Metal Inert Gas butt-welding to its full potential by optimising the geometry of the weld beads. The poor quality of welding, which is affected by several factors ...

U.S. Rep. Gabe Evans has introduced a bipartisan bill during National Police Week aimed at renaming the post office in the city of Evans to honor a fallen Weld County deputy. The legislation proposes ...

The man was pronounced dead on the scene at 2:25 p.m. The identity of the man will not be released until his next of kin is informed by the Weld County Coroner’s Office, after which the details will ...
