Fluoride‐Free Molten Salt Hydrate‐Assisted Synthesis of MXene in Air Down to 150 °C
Advanced Functional Materials, EarlyView.A novel low‐temperature shielded salt (LSS) approach enables the synthesis of MXenes in air at temperatures as low as 150 °C using MgCl2·6H2O/LiCl. This method demonstrates successful etching of challenging MXenes like Cr2CTx and Nb2CTx through the synergistic effects of Li+ ions and salt hydrate phase changes, while eliminating the need for inert ...

Application of an Extremal Result of Erdős and Gallai to the (n,k,t) Problem
Theory and Applications of Graphs, 2017 An extremal result about vertex covers, attributed by Hajnal to Erdős and Gallai, is applied to prove the following: If n, k, and t are integers satisfying n ≥ k ≥ t ≥ 3 and k ≤ 2t - 2, and G is a graph with the minimum number of edges among graphs on n ...

Reconfiguration of Vertex Covers in a Graph
IEICE Transactions on Information and Systems, 2015 Suppose that we are given two vertex covers \(C_{0}\) and \(C_{t}\) of a graph G, together with an integer threshold \(k\ge \max \{\left| C_0 \right| , \left| C_t \right| \}\). Then, the vertex cover reconfiguration problem is to determine whether there exists a sequence of vertex covers of G which transforms \(C_{0}\) into \(C_{t}\) such that each ...
