Mass and moment of inertia govern the transition in the dynamics and wakes of freely rising and falling cylinders [PDF]

, 2017
In this Letter, we study the motion and wake-patterns of freely rising and falling cylinders in quiescent fluid. We show that the amplitude of oscillation and the overall system-dynamics are intricately linked to two parameters: the particle's mass ...

Positively Charged Polymer‐Brush MOFs for Large‐Area, Pressure‐Resistant Gas Separation Membranes

Advanced Materials, EarlyView.
A universal POPA strategy enables positively charged polymer‐brush MOFs with self‐adaptive interfacial interlocking to resist aggregation under fast processing. This design ensures seamless dispersion within large‐area selective layers, achieving 1 m‐wide roll‐to‐roll fabrication of pressure‐resistant MMCMs with tunable CO2 separation performance ...

Significance of solar radiation and viscous dissipation on oscillatory and steady convective heat transfer around buoyancy-driven sphere using FDM scheme

Case Studies in Thermal Engineering
The innovation of this paper is to explore the transient behavior of heat transport and transient behavior of shear stress rate of unsteady fluid flow around the sphere surface in the presence of solar radiation, thermal buoyancy and viscous dissipation.

Oscillatory flow reactor design for biological process

Journal of Mechanical Engineering and Sciences, 2017
Oscillatory flow reactor (OFR) is a novel type of tubular reactor consisting of equally spaced orifice baffles (sometimes called doughnut baffles) fitted inside the column of the reactor. OFR can be used for biological and chemical processes such as crystallisation of paracetamol, biofuel production, and production of sterols in ester saponification ...

Amido‐Amine Co(II) Precursor‐Based Atomic/Molecular Layer Deposition Processes for Cobalt‐Organic Thin Films and Their Thermal Conversion to CoO Thin Films

Advanced Materials Technologies, EarlyView.
Three new atomic/molecular layer deposition processes are developed for Co‐organic thin films using a promising all‐nitrogen‐coordinated cobalt precursor. The study examines film growth, reaction mechanisms, chemical stability, and decomposition pathways of the resulting films through extensive characterization techniques and DFT calculations ...

Direct Growth of Transparent Boron Nitride Neutron Shielding Layer for Space Window

Advanced Science, EarlyView.
Direct growth of sp2‐sp3 hybridized BN (HBN) on quartz, enabled by an h‐BN buffer, produces transparent and stable films up to 80 µm thick with high transmittance and strong neutron shielding, making HBN a promising candidate for space windows in long‐term lunar missions.
