Validation of a X-Ray densitometry method for the determination of Eucalyptus grandis and Eucalyptus urophylla radial density profile [PDF]
, 2012 The X-ray densitometry is considered one of the main non-destructive techniques for the analysis of wood due to the high precision and practicality. The method has been applied in determining the density of the wood, and the density variation is a result

Advanced Functional Materials, EarlyView.Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...

Wood quality change in forest pine and spruce plantations [PDF]
, 2013 The results of research of the quality of wood from pine and spruce forest plantations are submitted. The density of wood from pine and spruce forest plantations in the whole planting is reduced compared with the control stands.

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus
Advanced Functional Materials, EarlyView.The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Effect of Density on the Natural Resistance of Ten Selected Nigerian Wood Species to Subterranean Termites [PDF]
Pro Ligno, 2013 The effect of density on the natural resistanceof ten selected Nigerian wood species to subterraneantermites was investigated. Wood samples obtainedfrom mixed-conversion boards were used such that thesamples contained both sapwood and the heartwood.They ...

Wood and fibre properties of fertilized Norway spruce [PDF]
, 2003 Very intensive forest management is relatively unexplored in Sweden, and while there is interest in pursuing e.g. the use of fertilizers on selected areas, there is concern about the quality of the wood when growth rate increases.

Advanced 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.

Is sensitivity to xylem cavitation a relevant physiological trait for fodder production in dry season? [PDF]
, 2013 In the Sahel parklands, trees can provide fodder during the dry season if they keep functional foliage. In such conditions, the xylem vessels sustain high tension which can induce cavitation, decrease the conduction of sap and lead to branch mortality ...

Advanced Functional Materials, EarlyView.This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.
