Random Graphs' Robustness in Random Environment

Austrian Journal of Statistics, 2017
We consider configuration graphs the vertex degrees of which are independent and   follow the power-law distribution. Random graphs dynamics takes place in a random   environment with the parameter of vertex degree distribution following   uniform ...

Sparse Vertex Cutsets and the Maximum Degree

The Electronic Journal of Combinatorics
We show that every graph $G$ of maximum degree $\Delta$ and sufficiently large order has a vertex cutset $S$ of order at most $\Delta$ that induces a subgraph $G[S]$ of maximum degree at most $\Delta-3$. For $\Delta\in \{ 4,5\}$, we refine this result by considering also the average degree of $G[S]$.

Synergistic Fluorine and Cyanide Co‐Modification to Reinforce Photoinduced Excitons Formation and Transfer for Efficient CO2 Photoreduction

Advanced Functional Materials, EarlyView.
An advanced F‐doped and ─CN group co‐modified FCCN is developed. Due to the synergistic effects of co‐modification in promoting photogenerated exciton generation, enhancing charge kinetics, expanding active interfacial areas, and optimizing CO2 interfacial reactions, the FCCN photocatalyst demonstrates excellent catalytic performance and high ...

Maya Blue‐Inspired Hybrid Coating for Robust and Superhydrophilic Solar Evaporators Using Commercial Black Acrylic Paint

Advanced Functional Materials, EarlyView.
This study demonstrates a Maya blue‐inspired hybrid solar evaporator using commercial black acrylic paint, achieving 98% solar‐thermal conversion efficiency and 2.39 kg m−2 h−1 water evaporation rate through a durable, hydrophilic organic–inorganic structure that enables scalable, cost‐effective desalination and wastewater purification.

Rigidity of epithelial tissues as a double optimization problem

Physical Review Research
How do cells tune emergent properties at the scale of tissues? One class of such emergent behaviors are rigidity transitions, in which a tissue changes from a solidlike to a fluidlike state or vice versa. Here we introduce a way for a tissue described by

Powering the Future: A Cobalt‐Based Catalyst for Longer‐Lasting Zinc–Air Batteries

Advanced Functional Materials, EarlyView.
A novel N‐doped graphitic shell‐encapsulated Co catalyst reveals superior bifunctional ORR/OER activity in alkaline media, empowering outstanding liquid and quasi‐solid‐state ZAB activity. The system delivers long‐term durability, a peak power density of 127 mW cm−2 and successfully powers an LED and a mini fan.

Differences in boundary behavior in the 3D vertex and Voronoi models.

PLoS Computational Biology
An important open question in the modeling of biological tissues is how to identify the right scale for coarse-graining, or equivalently, the right number of degrees of freedom.
