Amphiphilic Zeolitic Imidazolate Framework for Improved CO₂ Separation in PIM-1 Mixed Matrix Membranes. [PDF]

Angew Chem Int Ed Engl
An improvement in compatibility between filler ZIF‐94 and polymer PIM‐1 in mixed matrix membranes (MMMs) was achieved through ligand exchange with undecylimidazole (umIm). The modified ZIF‐94 (ZIF‐94‐umIm) presents amphiphilic character and high CO2 adsorption (2.34 mmol g−1 at 90 kPa and 0 °C).

Identification of histological threshold concepts in health sciences curricula: Students' perception

Anatomical Sciences Education, Volume 16, Issue 1, Page 171-182, January/February 2023., 2023
Abstract Students' metacognitive skills and perceptions are considered important variables for high‐quality learning. In this study, students' perceptions were used to identify histological threshold concepts (integrative, irreversible, transformative, and troublesome) in three health sciences curricula.

Water stress protection by the arbuscular mycorrhizal fungus Rhizoglomus irregulare involves physiological and hormonal responses in an organ‐specific manner

Physiologia Plantarum, Volume 175, Issue 1, January/February 2023., 2023
Abstract Arbuscular mycorrhizal fungi may alleviate water stress in plants. Although several protection mechanisms have already been described, little information is available on how these fungi influence the hormonal response to water stress at an organ‐specific level.

Cognitive Functioning in Adults with Phenylketonuria in a Cohort of Spanish Patients

Behavioural Neurology, Volume 2023, Issue 1, 2023., 2023
The early introduction of a low phenylalanine (Phe) diet has been demonstrated to be the most successful treatment in subjects with phenylketonuria (PKU), especially for preventing severe cognitive and neurological damages. However, it still concerns that even if treated in the first months of life with supplements and following a diet, they can show ...
