Flexural performance and failure mechanisms of 3D-printed corrugated-core sandwich panels reinforced with glass fibers

Purpose This study investigates the flexural performance and failure mechanisms of additively manufactured sandwich panels featuring 3D-printed corrugated cores and face sheets reinforced with E-glass fibers. The research aims to quantify the effects of core geometry, thermoplast...

Scenario-based optimisation of steel production technologies: A comparative assessment for Mobarakeh Steel Group's capacity enhancement

This study proposes a systematic framework for selecting optimal ironmaking technologies to enhance the sustainable production capacity of Mobarakeh Steel Company (MSC) in Isfahan, Iran. Five commercial technologies – Midrex, Corex, Finex, SL/RN, and ITmk3 – were evaluated across...

Hybrid modeling and energy optimization of NGL demethanizers using deep reinforcement learning

Abstract Cryogenic NGL demethanizers suffer from energy inefficiencies due to non-convex thermodynamic constraints. This study aims to implement a Deep Reinforcement Learning (DRL) framework to optimize energy consumption while respecting complex operational boundaries. A Soft Ac...

A numerical investigation of three-dimensional fluid flow in the bipolar plate of a PEMFC with novel configurations of serpentine flow channels

This study investigates modified serpentine flow channels for PEMFCs to reduce pressure loss and secondary-flow effects at bends. Conventional, symmetric, and hybrid configurations with different bend geometries were analyzed using three-dimensional CFD simulations based on press...

Rational design of nickel cobalt phosphate-sensitized tungsten-doped titania nanotubes (NiCoP@WTNT) for efficient light-assisted energy storage in flexible photo-supercapacitors

Developing efficient and low-cost systems for simultaneous solar energy harvesting and storage remains a critical challenge in next-generation energy technologies. Herein, we report a flexible photo-supercapacitor based on nickel–cobalt phosphate (NiCoP)-sensitized tungsten-doped...

Biorefining of whole cotton plant residues for bioethanol production with greenhouse gas emission reduction and social carbon benefits

This study evaluated the potential of cotton-processing residues, including leaves, bolls, linters, and stalks, as feedstocks for bioethanol production using ethanol-based organosolv pretreatment. Biomass samples were pretreated with 65 % (v/v) ethanol at 120, 150, and 180 °C for...

Chemical sand control in hydrocarbon reservoirs: a comprehensive review of techniques, mechanisms, and field applications

Sand production is one of the most important problems in the unconsolidated or weakly consolidated sandstone formations that causes about 70% of hydrocarbon reservoirs in the world. Sand production results in some related problems, such as permeability impairment, wellbore instab...

APEO-free black ceramic inkjet ink formulations based on Ni-substituted CoFeCrO4 spinel pigments

Abstract This study reports the development of high-performance black digital ceramic inks based on a Ni 0.5 Co 0.5 FeCrO 4 spinel pigment. A series of Ni x Co 1- x FeCrO 4 ( x = 0–1) pigments was synthesized via solid-state reaction. Calcination temperature (900–1100 °C) and pos...

Simulation-guided predictive machine learning framework for optimizing directed energy deposition of Fe-Mn alloys

This study proposes a hybrid Finite Element Modeling (FEM) and Machine Learning (ML) framework for predicting melt pool geometry in the Directed Energy Deposition (DED) of Fe-Mn alloys. A thermal FEM model based on the Goldak double-ellipsoidal heat source was developed and valid...

Sensitivity analysis of flood frequency to the length of the data recording period

Abstract Floods are the significant natural events that can have profound impacts. This study examines how the length of data records affects the sensitivity of continuous probabilistic models applied in the flood frequency analysis and record periods were analyzed. The FREQ soft...

A Ni(II) PNP pincer complex immobilized on SBA-15 as catalyst for the 4-nitrophenol hydrogenation

Abstract The Ni(II) complex [NiCl(bda)]+ containing the aliphatic PNP pincer ligand bis((2-diphenylphosphino)ethyl)amine (bda) was covalently immobilized on the mesoporous silica SBA-15. SBA-15 was functionalized with (3-chloropropyl)triethoxysilane as an anchoring agent, which w...
