Nonlinear optical properties of Au-nanoparticles conjugated with lipoic acid in water [PDF]

Journal of the European Optical Society-Rapid Publications, 2014
Gold nanoparticles were chemically conjugated with lipoic acid to control their optical properties. Z-scan and other optical techniques were used to characterize the non-linear behavior of the resulting nanostructured materials. The results show that the

Identification of Molecular Pathways Underlying Mn(II) Oxidation in Pseudomonas resinovorans

Environmental Microbiology, Volume 28, Issue 10, October 2026.
Transposon mutagenesis in biofilter‐associated Pseudomonas resinovorans MOB‐513 identifies a c‐di‐GMP‐dependent regulatory network involving type IV pili, two‐component systems, and diguanylate cyclases that controls Mn(II) oxidation and biofilm formation, providing new insight into microbial manganese cycling and biofilter performance.

Physiological and Sleep Profiles in Insomnia, OSA and COMISA: A Comparative Study in Portugal and Spain

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT Insomnia and obstructive sleep apnea (OSA) are common sleep disorders that often co‐occur as comorbid insomnia and sleep apnea (COMISA), worsening health outcomes. This study characterized and compared the physiological and sleep profiles of insomnia, OSA and COMISA in population‐based datasets from Portugal (n = 147) and Spain (n = 264 ...

Sundman‐Like Transformations and the NRT Nonlinear Schrödinger Equation

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14791-14810, 15 September 2026.
ABSTRACT We present a new generalization of the well‐known power‐type Sundman transformation, involving not only powers of the function but also of its derivative, along with its inverse. Our aim is to explore the use of such transformations in the derivation of solutions of ordinary differential equations and in the study of their properties.

Photon Recycling–Driven Photodetection Enhancement in Ni(AcO)2–MAPbBr3 Nanocomposite Waveguides

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Photon recycling is demonstrated as an effective mechanism to enhance perovskite photodetector performance. A Ni(AcO)2/MAPbBr3 nanocomposite waveguide enables long‐range propagation and reabsorption of photoluminescence photons, increasing photocurrent by ∼60%. Under pulsed excitation, reabsorption of amplified spontaneous emission further enhances the
