Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

open access: yesAdvanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Non-midical control of parasitic worms in pigs [PDF]

open access: yes, 2003
Generally there is a higher prevalence of intestinal parasites in organic pigs compared to conventional indoor pigs. It may be possible to reduce infection levels by ensuring that new animals are parasite free, using a moderate stocking rate, co-grazing ...

NATURAL RESEEDING IN PERENNIAL RYEGRASS/WHITE CLOVER DAIRY PASTURES

open access: yesProceedings of the New Zealand Grassland Association, 1988
The extent to which propagation of perennial ryegrass from seed can contribute to sward stability and the influence on this of spring pasture management (seedling competition and seed viability and losses was examined in a replicated plot experiment. Under hard grazing in late spring less than 5% of reproductive tillers reached flowering. Where grazing

Bedeutung der Megaherbivoren-Beweidung für die Renaturierung artenreicher Feuchtgrünländer auf ehemaligen Ackerflächen [PDF]

open access: yes, 2013
Species-rich wet grasslands in floodplains are on focus of European nature conservation policy. However, since the seventies of the last century large areas with grasslands in floodplains have been meliorated, ploughed and used for intensive cropping in ...

Phonon Engineering in Ultrathin Sn Films

open access: yesAdvanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

open access: yesAdvanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.
