Biopolymer‐Coated Paper Composites for Sustainable Packaging

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conventional plastic packaging, though dominant in food and flexible applications, poses serious environmental concerns due to its persistence and limited recyclability. To address this challenge, this study develops bio‐based coated paper composites as sustainable alternatives. Paper, while biodegradable, lacks adequate barrier properties. To

Optimization of Solid Phase Micro-Extraction (SPME) for Monitoring Occupational Exposure to Ethyl Benzene

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2009
Background and Objectives: Analytical methods for volatile organic compounds (VOCs) in different samples need extraction of compounds, by applying hazardous solvents. Solid phase micro-extraction (SPME) is a solvent-free equilibrium extraction method, in

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

In search of a new attractant for monitoring Stegobium paniceum L. (Coleoptera: Anobiidae)

Julius-Kühn-Archiv, 2018
Stegobium paniceum (L.) is a major pest for several stored products worldwide. Monitoring methods for this species, based on pheromone traps, are affected by the complexity and expensiveness of the chemical synthesis of the pheromone isomer [(2S,3R,1’R ...

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...
