ABSTRACT Rationale Hemicelluloses are abundant carbohydrate components in plant cell walls. They play a crucial structural role in binding cellulose microfibrils, in addition to other biological functions. Their high structural variability directly influences their biological properties, making it important to establish a structure–function ...

The influence of the microfibril angle on wood stiffness: a continuum micromechanics approach
Wood exhibits an intrinsic structural hierarchy. It is composed of wood cells, which are hollow tubes oriented in the stem direction. The cell wall is built up by stiff cellulose fibrils which are embedded in a soft polymer matrix.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

The plasticisation model of dye diffusion: Part 7
Abstract Re‐evaluation using the Williams‐Landel‐Ferry equation, of exhaustion/fixation/adsorption data previously reported for four classes of anionic dye onto three different types of wool substrate, revealed that thermally activated dyeing/desorption behaviour is governed by the thermally regulated structural relaxation times of the respective water‐

Studies on the Cell Wall Structure and on the Mechanical Properties of Norway Spruce [PDF]
The structure and the mechanical properties of wood of Norway spruce (Picea abies [L.] Karst.) were studied using small samples from Finland and Sweden. X-ray diffraction (XRD) was used to determine the orientation of cellulose microfibrils (microfibril ...

Slow crack growth : models and experiments [PDF]
The properties of slow crack growth in brittle materials are analyzed both theoretically and experimentally. We propose a model based on a thermally activated rupture process.

Modelling stomatal mechanics: a critical review
Summary The biomechanics of stomatal movements have fascinated scientists for almost 150 yr, yet we still lack a conclusive and coherent mechanistic understanding of the process. In this review, we present a framework that allows critical insight into the state of knowledge of stomatal biomechanics, with a focus on modelling approaches.

Background The crystallinity of cellulose is a principal factor limiting the efficient hydrolysis of biomass to fermentable sugars or direct catalytic conversion to biofuel components.

Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.
