Simultaneous Multi‐Resonant Thermally Activated Delayed Fluorescence and Room Temperature Phosphorescence from Biluminescent Nitrogen‐Containing Indolocarbazoles

open access: yesAdvanced Science, EarlyView.
An extremely rare type of organic biluminescent emission is reported that consists of delayed emission resulting from both the fluorescence (multi‐resonance thermally activated delayed fluorescence) and phosphorescence spectra at room temperature, and the lifetimes of the two processes exhibit opposing dependence with temperature.

On a conjecture of Kontsevich and Soibelman

open access: yes, 2012
We consider a conjecture of Kontsevich and Soibelman which is regarded as a foundation of their theory of motivic Donaldson-Thomas invariants for non-commutative 3d Calabi-Yau varieties.

Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor

open access: yesAdvanced Electronic Materials, EarlyView.
This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 5, May 2025.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Ultrafast Excitonic Transitions in Enantiopure and Racemic Squaraine Thin Films

open access: yesAggregate, Volume 6, Issue 3, March 2025.
Ultrafast optical excitation of both J‐ and H‐like bands in enantiopure ProSQ‐C16 thin films leads to highly similar spectral and dynamic responses, suggesting that a single aggregate type is responsible for the excitonic properties such as the giant circular dichroism reported previously.

An integrated scheduling and control scheme with two economic layers for demand side management of chemical processes

open access: yesAIChE Journal, Volume 71, Issue 6, June 2025.
Abstract Integrated dynamic scheduling (IDS) and economic nonlinear model predictive control (eNMPC) enable economic operation of chemical plants subject to volatile energy prices. Herein, we combine the two concepts into an integrated two‐layer scheme. Therein, IDS performs “long‐horizon” scheduling on a day‐ahead (DA) market and eNMPC “short‐horizon”

The complexity of some families of cycle-related graphs

open access: yesJournal of Taibah University for Science, 2017
In this paper, we derive new formulas for the number of spanning trees of a specific family of graphs – gear graphs, flower graphs, sun graphs and sphere graphs – using techniques from linear algebra, Chebyshev polynomials and matrix theory.
