Surface‐Interaction‐Driven Polarity Switching in II–V Cd3P2 Colloidal Quantum Dots for Infrared Photodiodes

Advanced Science, EarlyView.
. ABSTRACT Colloidal quantum dots (CQDs) based on II–V semiconductors offer attractive optical absorption and carrier transport properties for infrared optoelectronics, yet their device‐relevant electronic behavior remains poorly understood. In particular, Cd3P2 CQDs have been constrained by limited control over nanocrystal growth and carrier polarity.

Machine Learning for Designing Perovskites and Perovskite‐Inspired Solar Materials: Emerging Opportunities and Challenges

Advanced Science, EarlyView.
This review offers a comprehensive comparison between perovskites and perovskite‐inspired materials (PIMs), focusing on their crystal structures, electronic properties, and chemical compositions. It evaluates the applicability of machine learning (ML) descriptors and models across both material classes.

Integrating Automated Electrochemistry and High‐Throughput Characterization with Machine Learning to Explore Si─Ge─Sn Thin‐Film Lithium Battery Anodes

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A closed‐loop, data‐driven approach facilitates the exploration of high‐performance Si─Ge─Sn alloys as promising fast‐charging battery anodes. Autonomous electrochemical experimentation using a scanning droplet cell is combined with real‐time optimization to efficiently navigate composition space.

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

AIChE Journal, EarlyView.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG$$ {c}_{\mathrm{AG}} $$. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation.

Grid-symmetric generalized quadrangles

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2005
In a finite generalized quadrangle \(Q\) of order \((s, t)\) with \(s,t>1\) a line \(L\) is called an axis of symmetry if the group \(T(L)\) of all automorphisms that fix every line meeting \(L\) has the maximal possible order \(s\). A quadrangle \(Q\) is called grid-symmetric if \(Q\) has two disjoint axes \(M\) and \(L\) of symmetry such that two ...

Discovery of Novel Materials with Giant Dielectric Constants via First‐Principles Phonon Calculations and Machine Learning

Advanced Intelligent Discovery, EarlyView.
We discovered novel materials with giant dielectric constants by combining first‐principles phonon calculations and machine learning. Screening 525 perovskites identified six candidates. RbNbO3 was synthesized under pressure and showed ε ≈ 800–1000. This validates our framework as a powerful tool for high‐performance dielectric materials discovery.

Intriguing sets of partial quadrangles

, 2008
The point-line geometry known as a \textit{partial quadrangle} (introduced by Cameron in 1975) has the property that for every point/line non-incident pair $(P,\ell)$, there is at most one line through $P$ concurrent with $\ell$.

Generalized quadrangles and regularity

Discrete Mathematics, 2005
The point \(X\) of a generalized quadrangle (GQ) of order \((s,t)\) is regular if \(|(\{X,Y\}^\bot)^\bot|=t+1\) for every point \(Y\) not collinear with \(X\). Let the generalized quadrangle \(\mathcal S\) of order \((s,t)\) contain a regular point \(X\). Then the incidence structure \({\mathcal N}_X\) with pointset \(X^\bot-\{X\}\), with lineset \(\{(\

Translation ovoids of flock generalized quadrangles

European Journal of Combinatorics, 2004
Let \(S(F)\) be the generalised quadrangle (GQ) of order \((q^2,q)\) as defined by the fourgonal family \(F\). A translation ovoid \(O\) of \(S(F)\) is a set of \(q^3+1\) points of \(S(F)\) such that: (1) no two points of \(O\) are collinear on \(S(F)\); (2) \((\infty)\in O\) and there is a subgroup of the elation group \(G\) fixing \((\infty)\) which ...
