NEMI Tin Whisker Test Method Standards

October 12, 2021
Author(s)
I Boguslavsky, P Bush, E Kam-Lum, M Kwoka, J McCullen, K Spalding, K Vo, Maureen E. Williams
The need to better understand whisker growth has dramatically increased as component suppliers convert from tin-lead (SnPb) finishes to Pb-free finishes of Sn and low -alloy-content Sn-based finishes. Whiskers are spontaneous growth of metal filaments

NEXAFS Characterization of Poly(amino acids)

October 12, 2021
Author(s)
N T. Samuel, Daniel A. Fischer, David G. Castner
The near-edge x-ray absorption fine structure (NEXAFS) spectra of poly(amino acids) at the carbon, nitrogen and oxygen k-edges are investigated in this study. The poly(amino acid) NEXAFS spectra at the k-edges closely resemble the spectra of the

NiO: A Charge Transfer or Mott-Hubbard Insulator

October 12, 2021
Author(s)
T M. Schuler, D L. Ederer, S Itza-Ortiz, G T. Woods, T A. Callcott, Joseph Woicik
Using site-specific soft x-ray emission and absoroption spectroscopy in conjunction with site-specific x-ray photoelectron spectroscopy, we measure the magnitude of the insulating band gap of NiO to be approximately 2.0 eV, comparable to that predicted by

Non-Contact Tuning Fork Position Sensing for Hollow-Pyramid Near-Field Cantilevered Probes

October 12, 2021
Author(s)
A Ambrosio, E Cafali, S Spadaro, S Patane, Maria Allegrini, D Albert, E Oesterschulze
We demonstrate that tuning fork sensing provides a stable non-contact mode operation when applied to near-field optical microscopy employing cantilevered probes. Detrimental damping effects that have so far limited the practical use of these otherwise very

On the Future of Scientific Publication

October 12, 2021
Author(s)
Peter Strickland, Andrew J. Allen
We give a brief review of the rapidly changing landscape for scientific publication, especially in regard to scientific archival journal publication. Some of the many challenges and opportunities are outlined. These include the various forms of open access
