fracture toughness; mode I critical stress intensity factor; fracture mechanics; beech wood
Drvna Industrija, 2013 The aim of this research was to examine the content of catechin in normal and traumatic structures of beechwood by high performance liquid chromatography (HPLC). Two discs were sawn from each of six harvested trees.

On the signature of positive braids and adjacency for torus knots [PDF]
, 2014 The objects of study in this thesis are knots. More precisely, positive braid knots, which include algebraic knots and torus knots. In the first part of this thesis, we compare two classical knot invariants - the genus g and the signature σ - for ...

Advanced Science, EarlyView.A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...

Statistics of knots, geometry of conformations, and evolution of proteins. [PDF]
PLoS Computational Biology, 2006 Like shoelaces, the backbones of proteins may get entangled and form knots. However, only a few knots in native proteins have been identified so far. To more quantitatively assess the rarity of knots in proteins, we make an explicit comparison between ...

Advanced Science, EarlyView.We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...

DNA Nanoarray for Multiplexed RNA Detection With Single‐Molecule Readout
Advanced Science, EarlyView.A carrier‐based DNA nanoarray integrates programmable nucleic acid hybridization with solid‐state nanopore readout for direct RNA detection at single‐molecule resolution. A ternary encoding system enables 27 carriers with 81 addressable sensing sites, allowing the simultaneous identification of targets spanning a wide size range, from short microRNAs ...

Constructing Seamless Interfaces for Ultrastable Flexible Supercapacitors
Advanced Science, EarlyView.Seamless electrode/electrolyte and electrolyte/electrolyte interfaces with boosted interfacial toughness and adhesion are constructed by anchored interfacial polymerization and in situ polymerization, respectively. The achieved supercapacitor exhibits ultrahigh capacitance retention over 100,000 times of charge/discharge or folding deformation ...
