Direction‐Aware Period Prediction for Seismic Risk Assessment and Application to an Urban Tall Building Portfolio in China

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Reliable estimation of the principal periods is essential for regional seismic risk assessment (RSRA) of urban building portfolios. For tall buildings, however, existing period‐prediction formulas are constrained by the lack of representative data, while building translational azimuths are neglected despite their importance for regional ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

open access: yesGeological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

GO‐Loading‐Dependent Interfacial Architecture and Photocatalytic Behavior of MoSe2/Graphene Oxide Hybrid Materials

open access: yesJournal of the Chinese Chemical Society, EarlyView.
MoSe2/GO heterostructure exhibits enhanced photocatalytic dye degradation and CO2 reduction through efficient charge separation and electron transfer under UV‐visible light irradiation. ABSTRACT MoSe2/graphene oxide (MoSe2/GO) hybrids with controlled GO loadings were prepared through an ex‐situ hydrothermal route using commercial MoSe2 and GO as ...

Quantifying Effects of OM–Cation Interactions on Mid‐Infrared FTIR Absorption Spectra of Polygalacturonic Acid

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
The composition of organic matter (OM) was explained by effects of OM–cation interactions using polygalacturonic acid (PGA) as model substance. These effects were analyzed by COO− absorption bands in mid‐FTIR spectra. The change in intensity and wavenumber ranges of COO− bands in FTIR was quantified.

Use of predictive tools for the analysis of bioactive compounds in Crocus sativus L. flowers

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Crocus sativus L. (saffron) flowers have high bioactive potential because of their content of crocins, safranal and phenolic compounds. The development of predictive models based on near‐infrared (NIR) spectroscopy and partial least squares regression to estimate the antioxidant capacity of saffron flower, evaluated using oxygen ...
