Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures
Advanced Science, Volume 13, Issue 55, 5 October 2026.Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

Annalen der Physik, Volume 538, Issue 10, October 2026.Nonlocal quantum field theory predicts a finite phase‐space resolution, so even highly squeezed quantum states cannot be localized beyond a fundamental nonlocal limit, providing a potential experimental signature of nonlocality. ABSTRACT In a previous paper we derived an uncertainty relation for nonlocal fields by showing that the physical localization

International Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1143-1164, October 2026.This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...

Geoscience Data Journal, Volume 13, Issue 4, October 2026.To clarify the role of alpine ecosystems in water and carbon cycling, we measured eddy‐covariance fluxes in a Siberian dwarf pine ecosystem in the Japanese Alps. The quality of the flux data was assessed using micrometeorological criteria, and data gaps were filled using a random forest regression approach.

NMR in Biomedicine, Volume 39, Issue 10, October 2026.Machine learning models, particularly RFR (random forest regression), provide accurate and computationally efficient tumor pHe estimation from acidoCEST MRI without requiring auxiliary parametric maps. RFR achieved comparable performance to traditional Bloch fitting (RMSE: 0.020 vs.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer
Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and
