Abstract. At laboratory timescales, rock salt samples with different composition and microstructure show variance in steady-state creep rates, but it is not known if how this manifested at low strain rates corresponding deviatoric stresses. Here, we aim to quantify from the analysis of multilayer folds that developed over geological timescale Ocnele Mari mine Romania. The formation composed 90 ...

[1] We have developed a new experimental method to investigate the anelasticity of a polycrystalline solid at high homologous temperature (T/Tm = 0.6–0.7). By using a rock analogue (borneol polycrystals) and a partially molten rock analogue (borneol + melt) having low melting and eutectic temperatures (Tm = 204.5°C, Te = 43°C), respectively, testing high homologous temperature can occur near ro...

The transformation on heating LiCoMnO4, with a spinel structure, to LiCoMnO3, with a cation-disordered rock salt structure, accompanied by loss of 25% of the oxygen, has been followed using a combination of diffraction, microscopy and spectroscopy techniques. The transformation does not proceed by a topotactic mechanism, even though the spinel and rock salt phases have a similar, cubic close-pa...

Fluctuations in renewable energy production, especially from solar and wind plants, can be solved by large-scale storage. One of the possibilities is storing form hydrogen or methane–hydrogen blends. A viable alternative for salt caverns Lined Rock Cavern (LRC) underground most significant challenges LRC storage sealing liners, which need to have satisfactory mechanical properties. An experimen...

O3 layered sodium transition metal oxides (i.e., NaMO2, M = Ti, V, Cr, Mn, Fe, Co, Ni) are a promising class of cathode materials for Na-ion battery applications. These materials, however, all suffer from severe capacity decay when the extraction of Na exceeds certain capacity limits. Understanding the causes of this capacity decay is critical to unlocking the potential of these materials for b...

We reveal the existence of two different crystalline phases, i.e., the metastable rock salt and the equilibrium zinc blende phase within the CdS-shell of PbS/CdS core/shell nanocrystals formed by cationic exchange. The chemical composition profile of the core/shell nanocrystals with different dimensions is determined by means of anomalous small-angle X-ray scattering with subnanometer resolutio...

Endothelial dysfunction has an important role in the development and progression of salt-sensitive hypertension. Asymmetric dimethylarginine (ADMA), which is an endogenous inhibitor of nitric oxide synthase (NOS), has been demonstrated to be involved in the pathophysiological processes of endothelial dysfunction and salt-sensitive hypertension. However, it is currently unclear how high salt int...

Two hundred and thirty three Penan households from the Silat area, Ulu Baram and the Tutoh of the Fourth Division, Sarawak, were studied with regards to the prevalence of endemic goitre and the consumption of iodised salt. Of the 343 Penan women aged 15 years and above who were examined, 60.6% had goitres. The serious nature of this, in the case of the Penans, is indicated by the fact that 39.3...

Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...
