Detection of explosive markers using zeolite modified gas sensors [PDF]

open access: yes, 2012
Detection of hidden explosive devices is a key priority for security and defence personnel around the globe. Electronic noses, based on metal oxide semiconductors (MOS), are a promising technology for creating inexpensive, portable and sensitive devices ...

Osteometry of Duck Species in Northwestern Europe—A Reassessment of Woelfle's (1967) Dataset

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study revisits and expands upon Elisabeth Woelfle's (1967) foundational analysis of bone morphology and osteometry, which has long been a key reference for zooarcheological identification of duck species in northwestern Europe. By examining Woelfle's unpublished measuring protocols and incorporating 523 newly measured specimens, we ...

Radicals in carbonaceous residue deposited on mordenite from methanol [PDF]

open access: yes, 2016
It is shown that control of the degree of coking can lead to the observation of hyperfine structures in the carbonaceous residues deposited from methanol over mordenite (H-MOR) at temperatures relevant to the conversion of methanol to hydrocarbons.

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

open access: yesRare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

1D and 3D Carbon Nanomaterials Derived from Zeolite‐Based Catalysts: Synthesis and Applications

open access: yesSmall Structures, EarlyView.
Zeolites act as catalysts or catalytic templates to synthesize 1D and 3D carbon nanomaterials with uniform structures, enabled by their high surface area and uniform porous frameworks. The resulting carbon nanomaterials possess excellent surface area and electronic conductivity, supporting their use in energy storage, catalysis, electronics, gas ...

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

open access: yesBoreas, EarlyView.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

Clinical Diagnostics After Failed Hearing Screening in People With Intellectual Disabilities Do Not Often Take Place

open access: yesJournal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Individuals with intellectual disabilities are at higher risk of undiagnosed or inadequately treated hearing loss. This situation requires easily accessible hearing screening, diagnostics and intervention programmes in the living environment, i.e., in nurseries, schools, workplaces and homes.
