Archaeometric Analyses of Medieval Pottery from the Lower Danube Region, Romania
This study is about the pottery manufacturing in the Lower Danube region during the Early Medieval period (8th–10th c. AD). Optical microscopy, Particle induced X‐ray emission, and X‐ray diffraction analyses performed on 32 representative ceramic shards excavated at Pantelimonu de Sus, Constanţa County, Romania, provide clues on the raw materials and ...

Catalyst production for methanol synthesis includes an aging step. By ultrafast nucleation, occurring transient changes in the suspension important for later performance can be assessed. Analytical techniques deliver insights which lead to a mechanism in which zincian malachite is the main product, whereas a sodium species play an important role as ...

A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.
