Interstellar grains within interstellar grains
The Astrophysical Journal, 1991 Five interstellar graphite spherules extracted from the Murchison carbonaceous meteorite are studied. The isotopic and elemental compositions of individual particles are investigated with the help of an ion microprobe, and this analysis is augmented with structural studies of ultrathin sections of the grain interiors by transmission electron microscopy.

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Behavioral Response of Rhyzopertha dominica, Lesser Grain Borer, to Wheat Volatiles [PDF]
, 2018 The lesser grain borer is a grain pest that eats and damages grain products such as rice, corn, wheat, and millet (Edde, 2012). The lesser grain borer has a tendency to to reproduce rapidly and explode into big infestations under optimal conditions ...

Inflation in loop quantum cosmology: Dynamics and spectrum of gravitational waves
, 2010 Loop quantum cosmology provides an efficient framework to study the evolution of the Universe beyond the classical Big Bang paradigm. Because of holonomy corrections, the singularity is replaced by a "bounce".

Special Grain Boundaries in Ultrafine-Grained Tungsten
Nanoscale Research Letters, 2016 Field ion microscopy and computer simulation were used for the study of an atomic structure high-angle grain boundary in hard-drawn ultrafine-grained tungsten wire. These boundaries with special misorientations are beyond the scope of the coincident site lattice model.
