Plastics of the Future? Interdisciplinary Review on Biobased and Biodegradable Polymers: Progress in Chemistry, Societal Views, and Environmental Implications

Angewandte Chemie International Edition, Accepted Article.
Global demand to reduce polymer waste and microplastics pollution has increased in recent years, prompting further research, development, and wider use of biodegradable and biobased polymers (BBPs). BBPs have emerged as promising alternatives to conventional plastics, with the potential to mitigate the environmental burdens of persistent plastic waste.

An immersed boundary vector potential‐vorticity meshless solver of the incompressible Navier–Stokes equation

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 143-175, January 2023., 2023
We present a new strong‐form meshless solver combined with the boundary condition‐enforced immersed boundary method for the numerical solution of the nonstationary, incompressible, viscous Navier–Stokes equations in their stream function‐vorticity (in 2D) and vector potential‐vorticity (in 3D) formulation.

Long‐Lasting Hydrophilicity Induced by Ultraviolet Light on Surface Modified Hydrophobic Polylactic Acid

Journal of Applied Polymer Science, EarlyView.
In light of increasing applications of compostable materials, surface treatment on PLA to increase roughness and hydrophobicity has been investigated. However, modifying wettability might hinder degradation. UVC exposure has significant effects on the wettability of textured PLA substrates, allowing a complete wettability switch due to chain scission ...

On periodic water waves with Coriolis effects and isobaric streamlines

, 2012
In this paper we prove that solutions of the f-plane approximation for equatorial geophysical deep water waves, which have the property that the pressure is constant along the streamlines and do not possess stagnation points,are Gerstner-type waves ...

Two-phase choked flow of subcooled nitrogen through a slit [PDF]

Two-phase choked flow rate and pressure distribution data are reported for subcooled nitrogen flowing through a slit. The slip was a narrow rectangular passage of equal length and width. The inlet stagnation pressure ranged from slightly above saturation

A Novel 3D‐Printed Microfluidic Bioreactor With Electrospun Scaffold Integration as a Platform for Cardiovascular Tissue Engineering

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Cardiovascular diseases are one of the leading causes of global mortality. Treatment methods such as bypass graft operations, while often successful, can fail in cases of systemic disease or compliance mismatch. Tissue engineered vascular grafts may offer a potential solution, by means of an implantable cell‐seeded scaffold that can integrate ...

Analysis of distillation characteristics via CFD (computational fluid dynamics) of Korean traditional ‘Sojutgori’ and study on structure for distillation efficiency enhancement

Food Science &Nutrition, Volume 11, Issue 1, Page 590-598, January 2023., 2023
This study suggests a new design for tracking and modernizing the flow of fluid that changes inside according to the shape and material of "Sojutgori", a traditional Korean distiller. Abstract The design of the Korean traditional distiller ‘sojutgori’ was extracted as a digital sketch, and the internal fluid flow in the distillation process was tracked

Computation of nozzle flow fields using the PARC2D Navier-Stokes code [PDF]

Supersonic nozzles which operate at low Reynolds numbers and have large expansion ratios have very thick boundary layers at their exit. This leads to a very strong viscous/inviscid interaction upon the flow within the nozzle and the traditional nozzle ...

Reusing Waste Coffee Grounds as Electrode Materials: Recent Advances and Future Opportunities

Global Challenges, Volume 7, Issue 1, January 2023., 2023
Coffee industry produces more than 8 million tons of waste coffee grounds (WCG) annually. In recent decades, upcycling of WCG‐derived carbon into value‐added electrode materials has attracted growing interests owing to their low cost and high electrochemical properties.

Some flow phenomena in a constant area duct with a Borda type inlet including the critical region [PDF]

Mass limiting flow characteristics for a 55 L/D tube with a Borda type inlet were assessed over large ranges of temperature and pressure, using fluid nitrogen. Under certain conditions, separation and pressure drop at the inlet was sufficiently strong to
