Contrasting phagocyte respiratory burst responses in two European bat species during hibernation

open access: yesFrontiers in Immunology
Bats use various natural or artificial structures as hibernacula, resulting in a diversification of hibernation strategies. For example, caves provide a stable thermal microclimate for the greater mouse-eared bat (Myotis myotis), whereas above-ground ...

Nesting Biology and Seasonality of Long-Horned Bee Eucera nigrilabris Lepeletier (Hymenoptera, Apidae)

open access: yesSociobiology, 2016
We provide information on the nesting behavior, seasonality and nest soli type characteristics of Eucera nigrilabris Lepeletier, 1841 in Egypt. A nest was discovered in a canal bank in Abbis Village, Alexandria, Western Egypt. The species is protandrous,

ON THE CLASSIFICATION OF BEES [PDF]

open access: yesThe Canadian Entomologist, 1899
During the last winter, in connection with the study of the local bees, I had occasion to write out my views in regard to their classification, basing my observation upon the recent Apidae catalogue of Della Torre. As the views then arrived at form a fair statement of my present opinions, I venture to offer them in connection with the recent paper of ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Filariasis of parti-colored bats: phylogenetic analysis, infection prevalence, and possible vector mite identification

open access: yesFrontiers in Veterinary Science
IntroductionThe epidemiology of filarial infections is a neglected area of bat research, with little information on filarial species diversity, life cycles, host ranges, infection prevalence and intensity, parasite pathogenicity, or competent vectors ...

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

open access: yesAdvanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

open access: yesAdvanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

Emergent Spin Supersolids in Frustrated Quantum Materials

open access: yesAdvanced Materials, EarlyView.
This review highlights developments in the study of spin super‐solids in frustrated quantum materials. Advanced experimental characterizations and computational studies enable a comprehensive understanding of the driving mechanisms of spin super‐solidity in various layered transition‐metal compounds, bridging materials, experiments, and theory aspects.

Ferromagnetism of Molecular Beam Epitaxy‐grown Ultra‐thin Cr2Ge2Te6 Films Down to the Monolayer Limit on Si Substrates

open access: yesAdvanced Materials, EarlyView.
Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.
