Geometry Controls Confined Water Dynamics in Lipidic Mesophases

Angewandte Chemie, EarlyView.
An archaeal‐inspired lipidic mesophase allows precise control of interfacial curvature and water‐channel connectivity. Combining structural, thermodynamic, and ultrafast spectroscopies, we reveal that curvature governs the structure and reorientation dynamics of confined water, establishing a molecular‐level link between topology and dynamics in soft ...

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

Advanced Science, EarlyView.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Comparison of basal metabolic rate in individuals with a spinal cord injury and Harris-Benedict equation: a systematic review

Acta Universitatis Carolinae: Kinanthropologica, 2019
Tables for calculating the energy expenditure of the physical activities of the general population cannot be used due to the different paralysis of the upper or lower limbs in people with spinal cord injury (SCI). The purpose of this review is to compare

Effect of a combination of enzymes on the fundamental rheological behavior of bread dough enriched with resistant starch [PDF]

, 2016
The effect of three enzymes on the fundamental rheological parameters of bread dough with high content of resistant starch (RS) was studied. The RS was added as an alternative to increase the fiber ingestion while the enzymes, to overcome the gluten ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

Advanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.
