Lymphoid‐Tissue‐on‐Chip Recapitulates Human Antibody Responses In Vitro
The presented lymphoid‐tissue‐on‐chip system allows culture of primary human tonsil cells at organotypic high density under perfusion for up to 4 weeks, emulates immune response to soluble vaccines and vaccination via peripheral antigen‐presenting cells and represents a useful tool to assess cellular interactions during homeostasis, immune responses ...

Processing and fluid flow characteristics of hot isostatically pressed porous alumina for aerostatic bearing applications [PDF]
Despite their well known superior load and stiffness characteristics, the wide-spread use of porous aerostatic bearings in preference to other bearing types has been hampered by difficulties in controlling the permeability of the porous material during

Modeling and analysis of the static characteristics and dynamic responses of herringbone-grooved thrust bearings [PDF]
This paper describes a theoretical investigation of static and dynamic characteristics of herringbone-grooved air thrust bearings. Firstly, Finite Difference Method (FDM) and Finite Volume Method (FVM) are used in combination to solve the non-linear ...

A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Liquified Natural Gas Pump With Hydrostatic Journal Bearings
Lecturepg. 39In view of the inflammability of LNG (liquefied natural gas), submerged type pumps are normally used to protect against leaks. The overhaul interval of an LNG pump, therefore, is subject to the life of its ball bearings, because LNG is an ...

A Soft Robotic Jellyfish with Decoupled Actuators for Agile 3D Locomotion
This study presents a soft robotic jellyfish featuring a functionally decoupled actuation architecture. By separating propulsion, steering, and vertical regulation into independent modules, the robot overcomes conventional coupled‐motion limitations. Utilizing a passive‐valve‐based differential drag strategy and lateral water jets, it achieves agile 3D
