Microbial influence on the formation and subsequent changes of vertebrate tracks: field experiments on present‐day coastal sediments

Sedimentology, EarlyView.
ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

Earthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

Sodium Mesoxalate as Sacrificial Salt for Biomass‐Derived Hard Carbon // Polyanionic Cathode Na‐Ion Full Cells

Batteries &Supercaps, Volume 8, Issue 12, December 2025.
This study investigates whether using sodium mesoxalate as a sacrificial additive in two different cathode materials, Na3V2(PO4)3@C and Na3V2O2(PO4)2F@C, can compensate for the initial capacity loss experienced by biomass‐derived hard carbon anodes in full‐cell batteries.

Deciphering a New Electrolyte Formulation for Intelligent Modulation of Thermal Runaway to Improve the Safety of Lithium‐Ion Batteries

Advanced Functional Materials, Volume 35, Issue 39, September 25, 2025.
Diels‐Alder clicks chemistry addresses thermal runaway in lithium‐ion batteries. A thermoresponsive electrolyte with lithium salt in vinylene carbonate (VC) and 2,5‐dimethylfuran (DMFu) operates at room temperature but undergoes Diels‐Alder reactions at high temperatures, enabling a two‐step safety mechanism: a warning phase at ≈100 °C and complete ...

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

Advanced Functional Materials, Volume 35, Issue 30, July 24, 2025.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

An engineer, for what? On the different invitations a university extends to its students to acquire a professional identity

Journal of Engineering Education, Volume 114, Issue 3, July 2025.
Abstract Background The inquiry into the ultimate purpose of engineering practice and into how engineering students develop a professional identity aligned with it is a matter of great ethical and political importance. Engineering education programs play a key role here by interpellating or inviting students, both in explicit and implicit ways, to ...

Chemostat models with Monod and Haldane consumption functions and random environmental fluctuations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7412-7431, 15 May 2025.
In this paper, we study the asymptotic dynamics of two chemostat models with random environmental fluctuations modeled by means of real noise, where different consumption functions for the consumer species (Monod and Haldane) are taking into account. For each model, our main goal is to investigate the existence of deterministic attracting sets.

Generalized finite difference method applied to solve seismic wave propagation problems. Examples of 3D simulations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7706-7726, 15 May 2025.
The simulation of seismic wave propagation generally requires dealing with complex tridimensional geometries that are irregular in shape and have non‐uniform properties, features that make the application of the generalized finite difference method in this field interesting. This work continues the extensive developments by the research team focused on
