Surfaces of Constant Gaussian Curvature
U ovom radu upoznajemo smo se s plohama konstantne Gaussove zakrivljenosti. Pojam zakrivljenosti ima ključnu ulogu pri definiranju različitih vrsta ploha. Jedna od najvažnijih vrsta zakrivljenosti je upravo Gaussova zakrivljenost.

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots
Advanced Functional Materials, EarlyView.2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

Gaussian curvature directs the distribution of spontaneous curvature on bilayer membrane necks
, 2017 Formation of membrane necks is crucial for fission and fusion in lipid bilayers. In this work, we seek to answer the following fundamental question: what is the relationship between protein-induced spontaneous mean curvature and the Gaussian curvature at

Advanced Functional Materials, EarlyView.Autonomous scanning probe microscopy and multi‐objective Bayesian optimization navigate a ternary (Al,Sc,B)N combinatorial library. Registered photoluminescence, electron‐probe compositional mapping, and X‐ray diffraction connect local electromechanical function to defect‐sensitive emission, composition, and crystal structure.

Defect-populated configurations in nematic solid tori and cylinders
Physical Review ResearchWe make toroidal droplets of nematic liquid crystal and explore the defect-populated stable configurations that appear after heating to the isotropic phase and cooling back to the nematic phase. These configurations, as confirmed by simulations, are made

Advanced Functional Materials, EarlyView.This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Buffon's Problem determines Gaussian Curvature in three Geometries [PDF]
A version of the classical Buffon problem in the plane naturally extends to the setting of any Riemannian surface with constant Gaussian curvature. The Buffon probability determines a Buffon deficit.

Advanced Functional Materials, EarlyView.OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...
