In this work, transparent wood with soft-/hard-switchable and shape recovery capabilities was prepared by introducing an epoxy-based polymer with a glass transition temperature of about 0 °C into the delignified wood template. The epoxy resin was well filled in the pore structure of ...
A wide range of woody feedstock was used to produce the pellets, including both soft and hard woods. No information about the densification process was disclosed. After their production and local storage in the USA, the pellets were transported in bulk to a local port and loaded into an ...
Wood finishers refer to wood as open grained and close grained, which are terms reflecting the relative size of the pores, which determines whether the surface needs a filler. Earlywood and latewood within a growth increment usually consist of different kinds and sizes of wood cells. The ...
Wood anatomical structure significantly affects the mechanical properties of wood and wood composites. Parameters such as fiber length, wood density, orientation of microfibrils, and chemical composition of wood affect the properties of wood significantly. While a qualitative effect of anatomical features...
Polyurethanes are extremely versatile materials that can have various formulations to yield different plastic properties. Their mechanical properties can vary from soft and pliable to hard and rigid. Polyurethane materials can be engineered to have different mechanical and chemical properties by formulating...
A beautifully designed interior, offering 2,696 square feet of heated living space showcases decorative ceiling and wall details with wood accents. The first floor includes a sleek executive office with an ensuite bath and built-in bookcase featuring hidden storage, a dining room that will host ...
Matter makes them up, all things, you and me Some materials are hard, some are soft Some are smooth, and some are rough 物体就是事物,一个钟表,一个电视 一切都是物质组成的,包括你和我 有些材料硬,有些材料软 有些是光滑的,有些是粗...
Transparent wood is a new type of biocomposite with the potential to combine high optical transmittance with high mechanical properties for use in structural applications [1], [2]. It is based on a chemically treated wood template with low lignin content and preserved cellular structure, as in ...
This allowed to identify that bacterial decay was only present in the non-durable sapwood, even in very degraded piles. Moreover, the soft shell resulted to be rather uniform along the piles’ length. The analysis of decay, supported by micro-drilling and CT scans, allowed to develop ...
FDM 3D printing materials are available in a variety of color options. Various experimental plastic filament blends also exist to create parts with wood- or metal-like surfaces. Popular FDM 3D Printing Materials The most common FDM 3D printing materials are ABS, PLA, and their various blends. ...
