Shrinkage of High-Performance Concrete

open access: yes, 1999
This paper outlines an experimental and numerical study on the effect of w/c, silica fume and age on shrinkage of High-Performance Concrete (HPC). Cylinders of 8 types of HPC were cast. Carbonation and water-losses were studied parallel.

Use of wood shrinkage characteristics in breeding of fast-grown Acacia auriculiformis A. Cunn. ex Benth in Vietnam

open access: yes, 2009
Genotypic variation in wood total and partial shrinkage, basic density and growth traits was estimated in 51/2 year old Acacia auriculiformis trees in a clonal test.In the tangential, radial and longitudinal directions, the mean values were 2.64%, 1.64 ...

Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced 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 ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

open access: yesAdvanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

open access: yesAdvanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Ionic Liquid (IL) Compatibilization of Macropore‐Infused Nanocomposite Emulsion Thermosets (MINETs) for Structural Ion Transport

open access: yesAdvanced Materials Interfaces, EarlyView.
Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...

Artificial neural networks to estimate the physical-mechanical properties of amazon second cutting cycle wood

open access: yesMaderas: Ciencia y Tecnología, 2018
Timber from the second cutting cycle may make up the majority of future crop volumetric. However, there are few studies of the physical and mechanical properties of this timber, which are important to support the consolidation of new species. This study

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...
