Degradation of Dyes by Fungi: A Bibliometric Study and Bibliographic Review

open access: yesEnvironmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT The degradation of dyes from textile effluents is considered a major challenge due to their high potential for environmental contamination and health risks due to their toxicity. In this sense, the use of fungi for the degradation of these compounds is reported in the literature as an ecological alternative with great potential.

Conformal Coordinates for Molecular Geometry: From 3D to 5D

open access: yesJournal of Computational Chemistry, Volume 47, Issue 4, February 5, 2026.
The figure illustrates the conformal representation of ℝ3$$ {\mathbb{R}}^3 $$ in a non‐Euclidean five‐dimensional space ℍ$$ \mathbb{H} $$. Each point x∈ℝ3$$ x\in {\mathbb{R}}^3 $$ is described with two additional vectors, e0$$ {e}_0 $$ and e∞$$ {e}_{\infty } $$, so that Euclidean distances in ℝ3$$ {\mathbb{R}}^3 $$ can be recovered via inner products ...

Photonic QPU With Coherent States for Reversible Quantum Logic

open access: yesAnnalen der Physik, Volume 538, Issue 2, February 2026.
A photonic Quantum Processing Unit X (QPU X) design leveraging coherent‐state qubits and linear optics probabilistically implements fundamental logical gates‐including AND, OR, C‐NOT, C¯$\bar{C}$‐NOT, Toffoli (C2${\rm C}^2$‐NOT), and Fredkin (C‐SWAP)‐with success probabilities up to 1/4 for simpler gates.
