A new methodology for sub‐femtomolar detection of organic molecules through the combination of surface‐enhanced Raman spectroscopy and a superhydrophobic fluidic concentrator

open access: yesAnalytical Science Advances, Volume 6, Issue 1, June 2025.
Abstract A specific device that combines (1) surface‐enhanced Raman spectroscopy (SERS) and (2) superhydrophobic surfaces is developed to detect traces of analytes diluted at sub‐femtomolar concentration in water solutions. The first step of the analysis consists in the evaporation of a drop of the solution on the device, designed to concentrate all ...

Living Nondirected Kidney Donation: A Psychoanalytic Case‐Based Investigation of Altruism and Its Implications for Psychosocial Evaluation Guidelines

open access: yesInternational Journal of Applied Psychoanalytic Studies, Volume 22, Issue 2, June 2025.
ABSTRACT Why donate a kidney to a stranger? The history of living nondirected kidney donation, so‐called altruistic or Good Samaritan donation, is notable for its associated skepticism if not outright rejection. Since its possibility, transplantation institutes have been concerned over the motives of individuals who present to their clinics with the ...

The Role of Two Tyrosinase‐Like Glycoenzymes in Defining the Final Hue of Parrot Plumage

open access: yesPigment Cell &Melanoma Research, Volume 38, Issue 3, May 2025.
ABSTRACT Recent advances in avian melanogenesis have pinpointed multiple genetic loci associated with color polymorphisms, predominantly in the plumage of chickens, quails, and pigeons. However, the genetic basis of melaninization in parrot plumage remains elusive.

Elucidating New Particle Formation in Complex Terrain During the Winter 2022 Cold Fog Amongst Complex Terrain (CFACT) Campaign

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.
Abstract New particle formation (NPF) is a complex atmospheric phenomenon defined by the gas‐to‐particle conversion that leads to the sudden burst and growth in aerosol particles. Although chemical mechanisms for aerosol nucleation and growth are well established, the role of physical processes, such as turbulent mixing, within the atmospheric boundary
