Determination of relationship between thermal and mechanical properties of wood material [PDF]

open access: yes, 2019
Non-destructive test techniques are becoming increasingly important for assessment and maintenance. These techniques are very useful for assessment of materials such as wood, whose performance can vary considerably depending on the conditions of use.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Using Biodegraded Wood to Produce Boards Without Binders

open access: yesЛесной журнал
Currently, climate change leads to an increase in forest stand mortality. Dead trees are exposed to wood-destroying fungi. The lack of industrial methods for utilizing such raw materials is due to the low physical and mechanical properties of biodegraded

Dynamic viscoelastic properties of wood and acetylated wood in nonequilibrium states swollen by water or organic liquids

open access: yesJournal of Wood Science, 2020
To discuss the factors that greatly affect the stabilization and destabilization of the conformation of lignin caused by changes in temperature and/or swelling, the temperature dependence of the loss tangent (tanδ) of the sample given the different ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
