Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3

open access: yesAdvanced Materials Interfaces, EarlyView.
The subsurface Ba2+disorder, reveals the pairs of O vacancies (VO++$V_O^{ + + }$ s) and small polarons (SPe‐SPe−$SP_e^ - $ s) (Figure a–b), with the charge balance, as the following: Ti3++[VO+++SPe−]pair↔Ti4+${{T}_i}^{3 + } + {{[V_O^{ + + } + SP_e^ - ]}_{pair}} \leftrightarrow T_i^{4 + }$ which is consistent with observed low‐energy electron ...

Quantification of sleep in dairy cows in three different stages of lactation [PDF]

open access: yes, 2011
The aim of this project was to quantify the total sleep time in modern dairy cows during 24-hour periods and to investigate whether the total amount of sleep as well as time spent in different sleep stages varies between the dry period, early- and peak ...

Mirror Coating Research and Developments for Current and Future Gravitational‐Wave Detectors

open access: yesAdvanced Photonics Research, Volume 6, Issue 4, April 2025.
In gravitational‐wave detectors, research on mirror coatings is needed to mitigate thermal noise and enhance the detectors’ sensitivity. In this review, an overview of the latest worldwide research activities on coatings with low mechanical loss and low optical absorption is presented, including new coating designs such as multimaterial coatings and ...

Synthesis of spirolactones from carbonyls via carboborylation of N‐sulfonylhydrazones with alkoxycarbonylalkylboronic acids

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of

Drying off the dairy cow [PDF]

open access: yes, 2006
Most dairy cows generally have a non-lactating, “dry period” prior to parturition. As the milk production of dairy cows has increased dramatically during the last decades, cows managed conventionally with a 12 to 13 month-calving interval are dried off ...

On the Relentless Pursuit of an Oral Insulin Delivery System: How Far is Too Far?

open access: yesAdvanced Therapeutics, EarlyView.
Injectable insulin preparations have far outpaced oral ones by virtue of adequate bioavailability and are driven by innovations, including insulin pumps, real‐time blood glucose monitoring, and artificial intelligence. In contrast, oral insulin delivery systems, including nanomedicines, continue to struggle and lag due to varied reasons.
