Advanced Energy Materials, EarlyView.An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Dependence of shape on particle size for a crushed rock railway ballast [PDF]
, 2013 Laboratory testing of railway ballast poses practical difficulties because the particle size is often too large for most standard apparatus. There are therefore advantages in developing a scaled material whose behavior is representative of the full size ...

A reconnaissance magnetostratigraphy of Georgian Plio-Quaternary volcanic provinces (southern Caucasus) [PDF]
Geofísica Internacional, 2001 A palaeomagnetic and rock magnetic study was carried out on samples of the Djavakheti, Khrami and Kazbeki regions in Georgia. Samples were taken from 44 localities from 247 subaerial lava flows and from 3 lacustrine sedimentary layers, interbedded ...

Experimental studies of scale effects on shear strength, and deformation of rock joints [PDF]
, 1980 The effect of scale on shear strength is studied by performing direct shear tests on different sized samples of large joints. A rubber moulding system is used to obtain impressions of the roughness from a variety of natural joint surfaces.

Correlation Analysis of Uniaxial Compressive Strength and Elastic Modulus of Sedimentary Rocks
工程科学与技术, 2011 :An uncertain positive correlation has been found between uniaxial compressive strength and elastic modulus of rocks. In order to make this kind of uncertainty unambiguous and let rocks’elastic modulus, which is more difficultly achieved,could be ...

Pacing Early Mars Sedimentary Rock Formation
Geophysical Research LettersMars' sedimentary rock record documents past surface and/or near‐surface liquid water. However, paleoclimate models struggle to explain conditions warm enough for past liquid water.

Advances in Materials Science and Engineering, 2017 Under high stress, rock in the creep state is vulnerable to external impact load, causing the irreversible perturbation deformation of rock or even sudden failure. To explore the dynamic characteristics of sedimentary rock in the creep state, a siltstone
