A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Experimental and smoothed particle hydrodynamics‐finite element method simulation investigation of synergistic erosion mechanism of gangue‐based abrasive water jets

Deep Underground Science and Engineering, EarlyView.
This study proposes an eco‐friendly coal permeability enhancement technique by utilizing mine waste gangue as an abrasive in high‐pressure water jets. Integrating erosion experiments with smoothed particle hydrodynamics‐finite element method coupled simulations, the research study elucidates the flow field dynamics and a nonlinear solid–liquid ...

Effect of Wool Porosity on Mechanism of Solvent Scouring

Journal of the Textile Machinery Society of Japan, 1959
The degree of porosity (degree of opening) of a wool assembly has a great deal to do with the mechanism of practical processing. The author has made experimental measurements concerning the solvent scouring process as his second attempt to analyze the bearing which the degree of porosity of a wool assembly has on practical processing.

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Feasibility of solid waste-based geopolymers for anti-scouring protection of offshore scour pits: Macro-performance, micro-characterization, and sustainability

Case Studies in Construction Materials
This study proposes a method for anti-scour protection of offshore monopile foundations by using solid waste-based geopolymer materials. Fly ash (FA) and soda residue (SR) were mixed with sodium silicate (SS) solution to prepare fly ash-soda residue ...

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.

Investigation of the local scour depth of a pile foundation on the migrating sand waves seabed in the western South China Sea

Frontiers in Earth Science
In the western South China Sea, the diversity and complex genesis of sand waves lead to difficulties in measuring the actual scour depth of offshore wind turbine foundations. The present study employs methods such as in-situ multibeam echo sounding along

Piezosurgical partial ostectomy of the incisive bone for an ossifying fibroma removal in a 4‐year‐old Warmblood gelding

Equine Veterinary Journal, EarlyView.
Abstract Background Ossifying fibromas are uncommon in horses and complete surgical excision with premaxillectomy, maxillectomy or mandibulectomy is recommended. Piezosurgery has been previously used in equines only in one study. Objective To report a case of ossifying fibroma treated with piezosurgery and to describe its follow‐up.
