Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Cooling and Vibration in the CLIC Main Accelerating Structure [PDF]

open access: yes, 2001
The mechanical vibration induced by the flow of cooling water is discussed. The possibility of combining acceptable heat-transfer with laminar flow is investigated and an approximate formula for the effect of turbulent flow is given.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Advances in Micromanipulation Actuated by Vibration-Induced Acoustic Waves and Streaming Flow

open access: yesApplied Sciences, 2020
The use of vibration and acoustic characteristics for micromanipulation has been prevalent in recent years. Due to high biocompatibility, non-contact operation, and relatively low cost, the micromanipulation actuated by the vibration-induced acoustic ...

Analytical and experimental studies of flow-induced vibration of SSME components [PDF]

open access: yes
Components of the Space Shuttle Main Engines (SSMEs) are subjected to a severe environment that includes high-temperature, high-velocity flows. Such flows represent a source of energy that can induce and sustain large-amplitude vibratory stresses and/or ...

Flow Induced Vibrations in Engineering Systems and the Control of Flow Induced Vibrations. Chaotic Vibration in Poppet Valve Circuit.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995
In the previous paper we pointed out that chaotic vibrations can occur in poppet valve circuits due to nonlinearities. The chaotic motions in the poppet valve circuits include (a) period-doubling-type chaos, (b) Lorenz-type chaos and (c) intermittent-type chaos. In this paper, period-doubling-type chaos has been investigated in detail.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.
