Additive manufacturing (AM) is a broad definition of various techniques to produce layer-by-
layer objects made of different materials. In this paper, a comprehensive review of laser …

Pore connectivity is a measure of the fraction of pore space (vesicles, voids or cracks) in a
material that is interconnected on the system length scale. Pore connectivity is …

Magma may fragment as it ascends through the volcanic plumbing system to the Earth
surface, forming volcanic ash and pyroclasts (Scheu and Dingwell 2022, this issue). If the …

Silicic volcanic activity has long been framed as either violently explosive or gently effusive.
However, recent observations demonstrate that explosive and effusive behavior can occur …

Sintered materials are used as permeable filters and flow controllers, for which a validated
and general model of porosity and permeability is required. Here, we prepare samples built …

Silicic volcanic eruptions range in style from gently effusive to highly explosive, and may
switch style unpredictably during a single eruption. Direct observations of subaerial rhyolitic …

Coalescence of argon droplets with a radius of 25, 50, and 100 nm is studied with
computational methods. Molecular dynamics (MD) simulations are carried out to generate …

The fundamentals of our understanding of the mechanical compaction of porous rocks stem
from experimental studies. Yet, many of these studies use natural materials for which …

The modes of formation of clastic rocks result in a wide variety of microstructures, from poorly‐
sorted heterogeneous rocks to well‐sorted and nominally homogeneous rocks. The …

The laser irradiation step and the thermo-viscous flow during selective laser sintering
process applied to polymeric materials are analyzed both theoretically and by transient …
