A low‐cost protocol for the optical method of vulnerability curves to calculate P50

open access: yesApplications in Plant Sciences, Volume 13, Issue 2, March-April 2025.
Abstract Premise The quantification of plant drought resistance, particularly embolism formation, within and across species, is critical for ecosystem management and agriculture. We developed a cost‐effective protocol to measure the water potential at which 50% of hydraulic conductivity (P50) is lost in stems, using affordable and accessible materials ...

Salivary Extracellular Vesicles Separation: Analysis of Ultracentrifugation‐Based Protocols

open access: yesOral Diseases, Volume 31, Issue 3, Page 879-889, March 2025.
ABSTRACT Introduction The clinical potential of extracellular vesicles (EVs) is widely acknowledged, yet the standardization and reproducibility of its separation remain challenging. This study compares three protocols: ultracentrifugation (UC), UC with purification step (UC + PS), and a combined protocol using polymer‐based precipitation and UC (PBP +

Realization of finite groups as isometry groups and problems of minimality

open access: yesMathematische Nachrichten, Volume 298, Issue 2, Page 419-426, February 2025.
Abstract A finite group G$G$ is said to be realized by a finite subset V$V$ of a Euclidean space Rn$\mathbb {R}^n$ if the isometry group of V$V$ is isomorphic to G$G$. We prove that every finite group can be realized by a finite subset V⊂R|G|$V\subset \mathbb {R}^{|G|}$ consisting of |G|(|S|+1)(≤|G|(log2(|G|)+1))$|G|(|S|+1) (\le |G|(\log _2(|G|)+1 ...

Exploring the Limits and Balancing Efficiency, Transparency, and Esthetics in Ultrathin a‐Si:H Transparent Photovoltaic Devices

open access: yesSolar RRL, Volume 9, Issue 3, February 2025.
Alvarez‐Suarez et al. explore the limit tradeoff in efficiency and transparency esthetics for ultrathin a‐Si:H/oxide TPV devices. In this work, a complete optoelectronic characterization is done, and the optimal absorber thickness maximizing all the TPV parameters is assessed.

Electrical impedance characterization and modelling of Ti‐Β implants

open access: yesJournal of Biomedical Materials Research Part A, Volume 113, Issue 1, January 2025.
Abstract Commercially pure titanium (c.p. Ti) and Ti6Al4V alloys are the most widely used metallic biomaterials in the biomedical sector. However, their high rigidity and the controversial toxicity of their alloying elements often compromise their clinical success. The use of porous β‐Titanium alloys is proposed as a solution to these issues.
