Sintering Aid Strategy for Promoting Oxygen Reduction Reaction on High-Performance Double-Layer LaNiFeO Composite Electrode for Devices Based on Solid-State Membranes.

Strontium and cobalt-free LaNiFeO is considered one of the most promising electrodes for solid-state electrochemical devices. LaNiFeO has high electrical conductivity, a suitable thermal expansion coefficient, satisfactory tolerance to chromium poisoning, and chemical compatibility with zirconia-based electrolytes. The disadvantage of LaNiFeO is its low oxygen-ion conductivity.

Water stable colloidal lignin-PVP particles prepared by electrospray.

In this study, electrospray deposition has been used as a method to prepare lignin submicron spherical particles. Regularities of electrospraying of lignin solutions in DMSO were revealed. The influence of voltage, distance between electrodes, feed rate, temperature and concentration of lignin solution on the morphology, size and polydispersity of the obtained particles was determined.

Analysis of Maternal Prenatal Weight and Offspring Cognition and Behavior: Results From the Promotion of Breastfeeding Intervention Trial (PROBIT) Cohort.

Importance: Prenatal experiences can influence fetal brain development.

Objective: To examine associations of maternal prenatal body mass index (BMI) with cognition and behavior of offspring born full-term.

Design, Setting, And Participants: This cohort study examined follow-up data from a breastfeeding promotion intervention at 31 hospitals and affiliated polyclinics in the Republic of Belarus.

Delivery by caesarean section and offspring adiposity and cardio-metabolic health at ages 6.5, 11.5 and 16 years: results from the PROBIT cohort in Belarus.

Background: Caesarean delivery has been associated with later adiposity, perhaps via early programming or perhaps because of residual confounding by maternal or birth characteristics.

Objectives: Examine associations of caesarean delivery with adiposity and cardio-metabolic biomarkers.

Methods: Observational analysis of 15 069 children in the PROBIT cohort in Belarus.

In vitro adsorption-desorption of aflatoxin B1 on Pepper's lignins isolated from grassy plants.

The aflatoxin B1 (AFB1) adsorption properties of several lignins isolated by the Pepper's method from grassy plants: Helianthus tuberosus (LS-1), Atriplex patula (LS-2), Rhododendron tomentosum (LS-3), Althaea officinalis (LS-4), Lavatera (LS-5), and from wood of spruce Pícea (LS-6) were studied. The adsorption was conducted in vitro in the modeled conditions of the gastrointestinal tract. The correlations between the values of adsorption-desorption and the parameters of surface-porous structure and chemical structure of the lignins were established.
