On-surface synthesis platform for highly branched oligomers based on sequential C—C coupling and C—H activation of carbenes [PDF]

Nature Communications
On-surface synthesis is an emerging field for fabricating low-dimensional nanostructures. While carbenes are versatile reactive intermediates in solution-phase organic synthesis, they have rarely been explored in on-surface synthesis.

Accelerated directional growth of seaweed-like iron oxide branches driven by localized electric fields of gold nanoparticles in liquid [PDF]

Nature Communications
Branched nanostructures have attracted significant attention due to their potential applications across diverse fields. Precise control over branched morphology is essential for enhancing their functionality, yet it remains a considerable challenge.

On Minkowskian branching structures [PDF]

Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2009
Contrary to its initial idea, Belnap's (1992) theory of Branching Space-Times (BST) has models in which histories do not resemble relativistic space-times or any other physical space-times. The aim of this paper is to define a certain class of BST models, called "Minkowskian Branching Structures" (MBS), in which histories are isomorphic to Minkowski ...

A Mammary Organoid Model to Study Branching Morphogenesis

Frontiers in Physiology, 2022
Branching morphogenesis is the process that gives rise to branched structures in several organs, such as the lung, the kidney, and the mammary gland. Although morphologically well described, the exact mechanisms driving branch elongation and bifurcation ...

Interactive modelling of branching structures [PDF]

ACM SIGGRAPH 96 Visual Proceedings: The art and interdisciplinary programs of SIGGRAPH '96 on - SIGGRAPH '96, 1996
We present a rule based modelling system that allows the graphical interactive definition of botanical structures such as plants, including partial and global constraints and free form deformations. The main idea is to represent the rule system by a structure tree with components of high functionality.

On the Structure of RNA Branching Polytopes [PDF]

SIAM Journal on Applied Algebra and Geometry, 2018
The prevalent method for RNA secondary structure prediction for a single sequence is free energy minimization based on the nearest neighbor thermodynamic model (NNTM). One of the least well-developed parts of the model is the energy function assigned to the multibranch loops.

A new perspective on pore growth in anodic alumina films

Electrochemistry Communications, 2021
In this study, we use advanced analysis techniques to examine the nanostructures of anodic films formed on aluminum in various electrolytes, including oxalic acid and sulfuric acid, in the original state (without being chemically dissolved) and reveal ...
