Spectral‐Splitting Photovoltaic‐Thermal Solar Collectors Using Selective Hybrid Liquid‐Solid Optical Filters

Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.
A solar spectral‐splitting photovoltaic–thermal collector integrating a hybrid liquid‐solid optical filter is experimentally demonstrated. Selective optical filtering enables thermal–electrical decoupling, achieving elevated fluid temperatures while maintaining reduced PV operating temperatures.

High Value Utilization of Waste Biomass Carbon for Rapid CO2 Electroreduction and Stable Sodium‐Ion Storage

Carbon Neutralization, Volume 5, Issue 2, March 2026.
A strategy for the combined use of energy materials is proposed, in which bamboo‐derived carbon is simultaneously applied to DC‐SOFC and SIB. The regulating mechanisms of carbon microstructure and its strengthening effect on electrochemical performance were elucidated by comparing the fast Joule heating and traditional tube furnace heating processes ...

A density result on a BV-type space on Carnot groups

Bruno Pini Mathematical Analysis Seminar
In the setting of Carnot groups (connected, simply connected and stratified Lie groups), we prove a density result for a BV-type space previously introduced in [3].

Uniqueness and comparison principles for semilinear equations and inequalities in Carnot groups

Advances in Nonlinear Analysis, 2018
Variants of the Kato inequality are proved for distributional solutions of semilinear equations and inequalities on Carnot groups. Various applications to uniqueness, comparison of solutions and Liouville theorems are presented.

W2,p a priori estimates for nonvariational operators: the sharp maximal function technique

Bruno Pini Mathematical Analysis Seminar, 2018
We consider a nonvariational degenerate elliptic operator, structured on a system of left invariant, 1-homogeneous, Hörmander vector fields on a Carnot group, where the coefficient matrix is symmetric, uniformly positive on a bounded domain and the ...

The mirage of DNA methylation in transcriptional regulation of plants

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract “Cytosine methylation plays an important role in the regulation of gene expression in plants.” Some iteration of this statement can be found in most papers centered on plant epigenetics and has become a widely accepted textbook claim. However, our generalized understanding of how DNA methylation exerts control over transcription is now ...

Uniform Gaussian Bounds for Subelliptic Heat Kernels and an Application to the Total Variation Flow of Graphs over Carnot Groups

Analysis and Geometry in Metric Spaces, 2013
In this paper we study heat kernels associated with a Carnot group G, endowed with a family of collapsing left-invariant Riemannian metrics σε which converge in the Gromov- Hausdorff sense to a sub-Riemannian structure on G as ε→ 0.

Interbasin Analysis of the Poleward Expansion of Tropical Cyclone Potential Intensity

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Favorable thermodynamic environments for tropical cyclone (TCs), as measured by potential intensity (PI), expand to higher latitudes in a warming climate, in both observations and future simulations. However, this expansion rate has yet to be compared systematically between hemispheres and across basins.

Large sets at infinity and Maximum Principle on unbounded domains for a class of sub-elliptic operators

Bruno Pini Mathematical Analysis Seminar, 2019
Maximum Principles on unbounded domains play a crucial role in several problems related to linear second-order PDEs of elliptic and parabolic type. In the present notes, based on a joint work with prof. E.

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.
