Hydrogel‐Based Functional Materials: Classifications, Properties, and Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Conductive hydrogels have emerged as promising materials for smart wearable devices due to their outstanding flexibility, multifunctionality, and biocompatibility. This review systematically summarizes recent progress in their design strategies, focusing on monomer systems and conductive components, and highlights key multifunctional properties such as

Diving capabilities of diving petrels

open access: yesPolar Biology, 2014
5 pages, 3 figures, 1 table, supplementary material https://doi.org/10.1007/s00300-014-1483-0 In striking contrast to the general increase in diving ability with body mass in seabirds, amongst the Procellariiformes, the deepest dives appear to be by the smallest species.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

THE PROCEDURE BY EVALUATION OF DIVERS FOR THE DEEP DIVING [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists), 2014
When a diver is selected to perform a deep diving course, he has to pass a medical test and isn’t affected by the HPNS (High Pressure Nervous Syndrome). When a diver is selected to perform a deep diving course, he has to pass an evaluation stage in order

BLENDING RESPIRATORY GAS MIXTURES [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists)
The binary or ternary gas mixtures used in diving can be blended either by a successive and controlled injection of the component gases into containers of constant volume, following the pressure in the containers, or by a continuous flow mixing, with ...

Vascularization of the trachea in the bottlenose dolphin: Comparison with bovine and evidence for evolutionary adaptations to diving [PDF]

open access: yes, 2018
The rigid structure of the mammalian trachea is functional to maintain constant patency and airflow during breathing, but no gas exchange takes place through its walls.
