Fermi Level Shifts of Organic Semiconductor Films in Ambient Air.

Here, the Fermi level () shifts of several donor and acceptor materials in different atmospheres are systematically studied by following the work function (WF) changes with Kelvin probe measurements, ultraviolet photoelectron spectroscopy, and near-ambient pressure X-ray photoelectron spectroscopy. Reversible shifts are found with the trend of higher WFs measured in ambient air and lower WFs measured in high vacuum compared to the WFs measured in ultrahigh vacuum. The shifts are energy level and morphology-dependent, and two mechanisms are proposed: (1) competition between p-doping induced by O and HO/O complexes and n-doping induced by HO; (2) polar HO molecules preferentially modifying the ionization energy of one of the frontier molecular orbitals over the other.

Evaluating seagrass lipid biomarkers as indicator for organic carbon provenance and storage capacity in Zostera marina (L.) sediments.

Seagrass meadows are vital blue carbon habitats, with sedimentary organic carbon (OC) originating from both the seagrass itself and external sources. In this study, lipid biomarkers (n-alkanes), a well-known proxy for tracing OC sources, were used to indicate seagrass presence in sediment records and to correlate with sedimentary OC in cold-temperate seagrass (Zostera marina) sediments. We calculated a Zostera-ratio (seagrass/algae and terrestrial plants-ratio) using identified seagrass biomass n-alkanes (C, C, C, C, C) as a fingerprint for seagrass-derived OC.

Primary cutaneous rhabdomyosarcoma with EWSR1/FUS::TFCP2 fusion: four new cases with distinctive morphology, immunophenotypic, and genetic profile.

EWSR1/FUS::TFCP2-rearranged rhabdomyosarcoma (RMS) is a rare tumor with an aggressive clinical course, a predilection for craniofacial bones, spindled and/or epithelioid histomorphology, and positive immunohistochemistry (IHC) for epithelial and myogenic markers, along with variable ALK expression. Herein, we present four additional cases of primary cutaneous TFCP2-rearranged RMS. Notably, one tumor (case 1) displayed a varied pathological spectrum, initially presenting as a low-grade spindle cell neoplasm, but progressed into a high-grade spindle/epithelioid tumor.

Characterizing Methicillin-Resistant spp. and Extended-Spectrum Cephalosporin-Resistant in Cattle.

In the field of cattle medicine in Austria, to date, few studies have investigated the presence of methicillin-resistant and extended-spectrum β-lactamase-producing in Austria. For this reason, milk and nasal samples were examined for the presence of methicillin-resistant as well as fecal samples for extended-spectrum cephalosporin-resistant . The nasal and fecal swabs were collected during the veterinary treatment of calf pneumonia and calf diarrhea.
