Structure and properties of the cellulose microfibril
Journal of Wood Science, 2009 The current structural models of the cellulose microfibril as well as its mechanical and thermal properties are reviewed. The cellulose microfibril can be considered as a single thin and long crystalline entity with highly anisotropic physical properties.

Lithium atom storage in nanoporous cellulose via surface induced $\rm Li_2$ breakage [PDF]
Europhysics Letters, 104, 63003 (2013), 2014 We demonstrate a physical mechanism that enhances a splitting of diatomic $\rm Li_2$ at cellulose surfaces. The origin of this splitting is a possible surface induced diatomic excited state resonance repulsion. The atomic Li is then free to form either physical or chemical bonds with the cellulose surface and even diffuse into the cellulose layer ...

Cell Reports, 2023 Summary: Extracellular matrices contain fibril-like polymers often organized in parallel arrays. Although their role in morphogenesis has been long recognized, it remains unclear how the subcellular control of fibril synthesis translates into organ shape.

Advanced Sustainable Systems, EarlyView.This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals

Slow crack growth : models and experiments [PDF]
, 2007 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. Considering a 2D spring network submitted to an external load and to thermal noise, we show that a preexisting crack in the network may slowly grow because of stress fluctuations.

Failure of Mineralized Collagen Microfibrils Using Finite Element Simulation Coupled to Mechanical Quasi-brittle Damage [PDF]
Procedia engineering 10 (2011) 3193-3198, 2011 Bone is a multiscale heterogeneous materiel of which principal function is to support the body structure and to resist mechanical loading and fractures. Bone strength does not depend only on the quantity and quality of bone which is characterized by the geometry and the shape of bones but also on the mechanical proprieties of its compounds, which have ...

A medium supplemented with vegetable extract used for cellulose production of Rhodococcus SP. MI 2
Bioscience Journal, 2018 In this study, the most suitable vegetable extract was screened to use as non-conventional nutrient sources for cellulose production of Rhodococcus sp. MI 2. SH medium or a synthetic medium was used as a conventional or control medium.

Advanced Science, EarlyView.The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.
