Modeling deep-bed grain drying using Comsol Multiphysics [PDF]

open access: yes, 2013
CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate.

Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

open access: yesAdvanced Functional Materials, EarlyView.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Laser‐Welded Cellulose‐Carbon Nanotube Nanocomposites as a 3D Scaffold of Si Anodes for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Si anode comprising entangled networks of cellulose and SWCNT (C‐CNT) nanocomposites as an anode electrode for a high‐performance LIB is realized by fully utilizing the generated microstructure of a novel conductive 3D scaffold via a low‐temperature and eco‐friendly process. Additionally, localized heating via photo‐thermal conversion can be utilized

Modeling the Drying Kinetics of Green Bell Pepper in a Heat Pump Assisted Fluidized Bed Dryer [PDF]

open access: yes, 2016
In this research, green bell pepper was dried in a pilot plant fluidized bed dryer equipped with a heat pump humidifier using three temperatures of 40, 50 and 60C and two airflow velocities of 2 and 3m/s in constant air moisture.

Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

open access: yesAdvanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Influence of different pretreatments on the colour of dried pears [PDF]

open access: yesJournal on Processing and Energy in Agriculture, 2013
As a physical property, colour is an important indicator of the product quality. The purpose of this paper is to examine the effects of different pretreatments on the pear colour alteration during and after combined drying.

Multi-scale model for heat and mass transfer during rice drying [PDF]

open access: yes, 2013
Grain drying is a simultaneous heat and moisture transfer problem. The modeling of such a problem is of significance in understanding and controlling the drying process.

Reduced complexity models for water management and anode purge scheduling in DEA operation of PEMFCs [PDF]

open access: yes, 2010
In this work, the dynamic behavior of Fuel Cell operation under Dead-Ended Anode conditions is shown. A DEA can be fed with dry hydrogen, since water crossing through the membrane is sufficient to humidify the fuel.
