From the “Green Turn” to the Recognition of an Autonomous Right to a Healthy Environment: Achievements and Challenges in the Practice of UN Treaty Bodies

open access: yesAJIL Unbound, 2023
Since the end of the 2010s, some of the UN human rights treaty bodies have affirmed and enhanced states’ obligations in relation to the environment. This “green turn,” deeply influenced by the jurisprudence of the regional human rights tribunals and the ...

General pseudo self-adjoint boundary conditions for a 1D KFG particle in a box

open access: yesPhysics Open, 2023
We consider a 1D Klein–Fock–Gordon particle in a finite interval, or box. We construct for the first time the most general set of pseudo self-adjoint boundary conditions for the Hamiltonian operator that is present in the first order in time 1D Klein ...

Effective computational schemes for a mathematical model of relativistic electrons arising in the laser thermonuclear fusion

open access: yesResults in Physics, 2020
This research paper investigates the computational wave solutions of the nonlinear Klein–Fock–Gordon (KFG) equation by applying two effective recent computational schemes. The nonlinear KFG model is a quantized version of the relativistic energy–momentum

Record-High Performance Hyperfluorescent OLEDs Achieved via Electronic Structure Control of Chlorine-Diversified MR-TADF Emitters. [PDF]

open access: yesAdv Sci (Weinh)
A late‐stage diversification strategy for the benchmark MR‐TADF emitter ω‐DABNA enables precise electronic structure control via chlorine‐activated functionalization. The resulting derivatives achieve tunable emission from 523 to 533 nm with record‐high EQE1000 up to 34.0% and excellent color purity (CIEy = 0.70–0.73), establishing a versatile platform

Comparison of the Wiener and Kirchhoff Indices of Random Pentachains

open access: yesJournal of Mathematics, 2021
Let G be a connected (molecule) graph. The Wiener index WG and Kirchhoff index KfG of G are defined as the sum of distances and the resistance distances between all unordered pairs of vertices in G, respectively.

The closed-form soliton solutions of the time-fraction Phi-four and (2+1)-dimensional Calogero–Bogoyavlenskii–Schiff model using the recent approach

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The Phi-four (PF) model is a variation of the familiar Klein–Fock–Gordon​ (KFG) model. Quantum effects, ultra-short pulse propagation in optical fibers, character of de-Broglie waves, wave-particle duality, composite particles of spineless relativistic ...
