Investigation of the Nanoporous Structure of Thermally Modified Carbon Materials by Small-Angle X-ray Scattering

open access: yesФізика і хімія твердого тіла
The nanoporous structure of thermally modified carbon materials was studied using the small-angle X-ray scattering (SAXS) method. An analysis of scattering curves in Guinier and Porod coordinates was carried out for the initial and thermally activated ...

Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.

Prospects for new physics from gauge left-right-colour-family grand unification hypothesis

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Given the tremendous phenomenological success of the Standard Model (SM) framework, it becomes increasingly important to understand to what extent its specific structure dynamically emerges from unification principles.

Design of oscillatory neural networks by machine learning

open access: yesFrontiers in Neuroscience
We demonstrate the utility of machine learning algorithms for the design of oscillatory neural networks (ONNs). After constructing a circuit model of the oscillators in a machine-learning-enabled simulator and performing Backpropagation through time ...

Split NMSSM from dimensional reduction of a 10D, N $$ \mathcal{N} $$ = 1 E 8 over SU(3)/U(1) × U(1) × Z 3

open access: yesJournal of High Energy Physics
We examine an extension of the Standard Model which results from a 10D, N $$ \mathcal{N} $$ = 1, E 8 gauge theory. The theory is dimensionally reduced over a M 4 × B 0 / Z 3 space, where B 0 is the nearly-Kähler manifold SU(3)/U(1) × U(1) and Z 3 is a ...
