Unraveling Microporosity in Hard Carbons: Insights Into Sustainable Sodium‐Ion Battery Materials

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
Hidden microporosity in hard‐carbon anodes for sodium‐ion batteries is revealed by small‐angle X‐ray scattering combined with Ruland–Smarsly analysis, including closed pores inaccessible to gas adsorption. Comparing petroleum‐derived and biowaste‐derived carbons links nanoscale disorder, surface area, and pore architecture to sodium storage ...

Impact of Particle Morphology on Processing and Performance of Sodium Ion Anodes

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
Particle morphology of hard carbons (HC) in sodium‐ion batteries (SIB) is shown to govern electrode packing and transport behavior related to sodium metal plating. Spherical particles enable denser electrodes and higher volumetric capacity but increase tortuosity, polarization, and plating risk at higher rates. Nonspherical particles preserve electrode

Kaon GTMDs in the Dyson–Schwinger equations using contact interaction

European Physical Journal C: Particles and Fields
An array of the kaon twist-two, three, four generalised transverse momentum dependent parton distributions (GTMDs) has been investigated within the framework of covariant and confining Dyson–Schwinger equations using contact interaction.

The Wigner distribution function of partially coherent light

, 1981
The concept of the Wigner distribution function is applied to stochastic signals, in particular to partially coherent light. Relations between the Wigner distribution function, the power spectrum and related subjects are formulated. Some inequalities for

A Review of Fault‐Tolerant Control Applications in Process Equipment: Boilers, Heat Exchangers, Pumps, Turbines, and Engines for Greater Reliability

Engineering Reports, Volume 8, Issue 9, September 2026.
The article explores ways such as ultrasonic guided wave testing, infrared thermography, acoustic emission, vibration analysis, and oil analysis to prevent faults from affecting the plant and help with fault isolation. It focuses on how FTC is combined with modern tools like Artificial Intelligence (AI), the Internet of Things (IoT), sliding mode ...

Causality of ultrafast photoionization from argon using an ab initio relativistic approach

New Journal of Physics
We study real-time photoionization flux at the $3s$ Amusia–Cooper minimum (ACM) in argon using ab initio simulations with the relativistic time-dependent configuration-interaction singles (RTDCIS) method in length (LG) and velocity (VG) gauges.

Quantum Field Theory in the Weyl–Wigner Representation

Universe
The Wigner representation for quantum mechanics of particles is generalized to Bose fields. The standard Hilbert space quantization becomes, via the Weyl transform, a quantization method that consists of adding a Gaussian zeropoint field distribution to ...

The Wigner distribution of Gaussian weakly harmonizable sprocesses

, 2006
The paper treats the Wigner distribution of scalar-valued stochastic processes defined on R-d. We show that if the process is Gaussian and weakly harmonizable then a stochastic Wigner distribution is well defined. The special cas, of stationary processes
