Optimally Carbonized Mangrove Wood–Derived Hard Carbon with a Soft Carbon Coating for High‐Performance Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
High‐performance SIB anodes are developed using mangrove wood–derived hard carbon, optimized through controlled carbonization temperatures and pitch‐derived soft carbon coatings. The resulting PC‐10 composite achieves a superior reversible capacity of 297.5 mAh g−1 and an 82% ICE by suppressing irreversible reactions and enhancing interfacial stability

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

open access: yesEnergy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

open access: yesEnergy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

open access: yesEnergy Science &Engineering, EarlyView.
Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

open access: yesFire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

Determination of chain conformation of polysaccharides using a SEC‐MALLS‐Vis

open access: yesFood Biomacromolecules, EarlyView.
Abstract For polysaccharides, biological activity is associated with the chemical structure as well as the chain conformation. The chain conformation is conventionally derived from the scaling relationships between weight‐average molecular weight (Mw) and intrinsic viscosity ([η]) or the radius of gyration (Rg) or the translational diffusion ...
