Time-Resolved Synchrotron-Based Investigation of Reactive Pore Evolution in Sandstone for CO 2 Storage

Abstract Understanding mineral dissolution in heterogeneous porous media is critical for predicting the evolution of subsurface systems during geological CO2 storage. Here, we integrate time-resolved synchrotron techniques, 4D X-ray microtomography (μ-CT), X-ray fluorescence (TR-...

Self-Assembled Monolayers and Solvent Composition Control the Orientation and Work Function of Pyrene-Based [7]Helicenes

Abstract Self-assembled monolayers (SAMs) and solvent composition critically influence the orientation and electronic properties of functional organic molecules, paving the way for energy conversion and optoelectronic devices. PeakForce quantitative nanomechanics atomic force mic...

Improved nanoparticle productivity via flat-top 49-beam nanosecond pulsed laser ablation in liquids

Abstract Pulsed laser ablation in liquids (PLAL) is a versatile and environmentally friendly technique for producing surfactant-free, high-purity nanoparticles (NPs) suitable for applications in catalysis and biomedicine. However, its industrial scalability is limited by low thro...

Metropolis and kinetic Monte Carlo methods for studying protein interactions

Abstract Protein–protein interactions are stochastic and play a central role in determining the structural and dynamic properties of biological systems. Computational approaches that account for the probabilistic nature of these interactions are therefore essential for understand...

QDL Historical Predictions Ledger — Version 1.0

This record freezes Version 1.0 of the QDL Historical Predictions Ledger prior to examination of Nature-sensitive results associated with its principal prospective tests. The ledger distinguishes prospective predictions from retrodictions, conditional model outputs, structural re...

Oxygen-Vacancy-Controlled Band-Gap Engineering in Fe/Co Co-doped La-Modified Bismuth Titanate: Integrated Experimental and First-Principles Analysis

Abstract Layered Aurivillius ferroelectrics offer a route to multifunctional band-gap engineering, yet the role of oxygen vacancies in band-edge reconstruction in Fe/Co-modified compositions remains poorly resolved. Here, oxygen annealing of Bi3.25La0.75Ti2.60(Fe0.50,Co0.50)0.40O...

Sym-EFT: Accelerating Effective Field Theory of Large Scale Structure with Symbolic Regression

Abstract We present an emulator suite for the one- and two-loop cold dark matter power spectrum from the Effective Field Theory of Large Scale Structures (EFTofLSS). Specifically, we emulate separately the various contributions to the one- and two-loop parts of the power spectrum...

Instantaneous radiative forcings due to the first indirect effect linked to low-level liquid clouds in the Amazon

Abstract. Much of the present uncertainty in effective radiative forcing due to aerosol–cloud interactions (ERFaci) arises from aerosol–cloud adjustments. Nevertheless, estimating instantaneous radiative forcing due to aerosol–cloud interactions (IRFaci) remains important because...

Climate and dengue synchronization in southern Brazil: a municipal analysis with cross-state validation

Dengue transmission is rapidly expanding beyond its historical tropical range, raising concerns about how climate change may alter the collective dynamics of epidemics. While most studies focus on transmission risk, much less is known about how climate affects the synchronization...

Coupling electric and magnetic dipoles in Janus nanoplatelets via surface-selective hybridization

Coupling electric and magnetic dipoles within nanoscale building blocks offers a promising strategy for creating hybrid materials with coupled magnetic and electric functionality. Here, we demonstrate a proof-of-concept approach for realizing this concept in Janus nanoparticles t...

Boosting NIR Emissions and Thermal Resistance in Cr3+-Doped MgGa2O4 Semiconductor Microcrystals by Energy Transfer for Smart Detection

High-radiant-intensity broadband near-infrared (NIR) emitters are highly desirable for nondestructive testing, night-vision imaging, and information encryption. However, the exploration of phosphors that possess both high luminous efficiency and outstanding thermal stability cont...

Extending the mineralogy of U 6+ (VII.): Kristekite, [Cu 2 (H 2 O) 4 (UO 2 )(SeO 3 ) 3 ]·4H 2 O, a new mineral from Příbram, Czech Republic.

The new mineral kristekite (IMA2025-101), [Cu 2 (H 2 O) 4 (UO 2 )(SeO 3 ) 3 ]•4H 2 O, was found in the dump material of the former uranium mine at Bytíz, near Příbram, Central Bohemia, Czech Republic, where it occurs as hedgehog-like aggregates, consisting of yellowish-green tabu...
