β‐Sheets Orientation in Physisorbed Protein Layers

Advanced Materials Interfaces, Volume 12, Issue 6, March 16, 2025.
The β‐sheets in physisorbed layers of anti‐immunoglobulin G and bovine serum albumin on gold exhibit a non‐isotropic orientation, with a partial ordering that favors a tilt toward the gold surface. This preferential alignment is evaluated through a comparative analysis of polarization‐modulation infrared reflection‐absorption (PM‐IRRAS) spectra and ...

Fabrication and characterization of 2D photonic crystals for new optoelectronic devices [PDF]

, 2006
Photonic crystals were discovered in the 80s as a possible solution to the control of the spontaneous emission and localization of light. Nevertheless only in recent years, with the spreading of nanotechnologies, the first applications with high ...

Reference values for cerebral and peripheral tissue oximetry in children: A clinical TD‐NIRS study

Acta Paediatrica, Volume 114, Issue 3, Page 515-525, March 2025.
Abstract Aim Current non‐invasive near‐infrared spectroscopy (NIRS) tissue oximetry suffers from suboptimal reproducibility over probe repositioning, hindering clinical threshold establishment. Time Domain‐NIRS (TD‐NIRS) offers higher precision but lacks sufficient paediatric data, preventing effective clinical application.
