Edge-disjoint double rays in infinite graphs: a Halin type result [PDF]
, 2014 We show that any graph that contains k edge-disjoint double rays for any k>0 contains also infinitely many edge-disjoint double rays.

On tree-decompositions of one-ended graphs [PDF]
, 2018 A graph is one-ended if it contains a ray (a one way infinite path) and whenever we remove a finite number of vertices from the graph then what remains has only one component which contains rays. A vertex $v$ {\em dominates} a ray in the end if there are

Nature Nanotechnology, 2010 Graphene has significant potential for application in electronics, but cannot be used for effective field-effect transistors operating at room temperature because it is a semimetal with a zero bandgap. Processing graphene sheets into nanoribbons with widths of less than 10 nm can open up a bandgap that is large enough for room-temperature transistor ...

Logarithmically-small Minors and Topological Minors [PDF]
, 2014 Mader proved that for every integer $t$ there is a smallest real number $c(t)$ such that any graph with average degree at least $c(t)$ must contain a $K_t$-minor.
