Biomass DNA: An Emerging Building Block for Advanced Materials

Advanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Over 95% Optical Reflectance From Structurally Modulated All‐Biopolymer Multilayers

Advanced Materials, EarlyView.
A new dense–porous design turns ordinary polysaccharides into highly reflective photonic multilayers. Alternating dense pectin and porous cellulose nanofiber layers create strong refractive‐index contrast without inorganic or synthetic polymers, enabling nearly perfect visible reflection, high near‐infrared reflection, broadband metallic‐like colors ...

COMPARISON OF DRYING SHRINKAGE AND DRYING CREEP KINETICS IN CONCRETE

Acta Polytechnica CTU Proceedings, 2018
The aim of this paper is to show and compare the time evolution of drying shrinkage and drying creep in concrete from three different perspectives. The first one analyzes the basic equations defined in the most common design codes and prediction models for the description of the long-term behavior of concrete (ACI 209, EC2, Model Code 2010, B3, B4 ...

Cigarette filter material and polypropylene fibres in concrete to control drying shrinkage [PDF]

, 2012
Due to a reduction in demand for cigarette filter material (North East UK), significant quantities have arisen that have little commercial value. The filter manufacturers have been looking for another outlet for their product and polypropylene fibre ...

Evaluation of the Free Volume Theory to Predict Moisture Transport and Quality Changes During Broccoli Drying [PDF]

, 2010
Moisture diffusion in porous broccoli florets and stalks is modeled using the free volume and Maxwell-Eucken theories. These theories are based on the mobility of water and concern the variation of the effective diffusion coefficient for a wide range of ...

Defined Matrices Reveal Epithelial‐ and Mesenchymal‐Specific Responses to Stiffness and Adhesion in Human iPSC‐Derived Intestinal Organoids

Advanced Materials, EarlyView.
Defined PEG hydrogels enable human iPSC‐derived intestinal organoid culture without Matrigel. PEG‐ and Matrigel‐cultured organoids both support duodenal‐like epithelial identity, but direct comparison reveals subtle epithelial differentiation‐marker shifts and stronger mesenchymal ECM‐remodeling/integrin programs in PEG.

The potential of computer vision, optical backscattering parameters and artificial neural network modelling in monitoring the shrinkage of sweet potato (Ipomoea batatas L.) during drying

, 2017
Background: Drying is a method used to preserve agricultural crops. During the drying of products with high moisture content, structural changes in shape, volume, area, density and porosity occur.

Drying Shrinkage of Cast-In-Situ Concrete in Half-Precast Concrete System Under Restraint Conditions

International Journal of Concrete Structures and Materials
In half-precast concrete (PC) systems, the drying shrinkage of cast-in-place (CIP) concrete is significantly greater than that of PC slabs, which are typically manufactured in factories using well-controlled steam curing. In actual construction, however,
