Development of plastic areas in angle points zone under concentrated force [PDF]

, 2014
Отримано аналітичний розв’язок антиплоскої пружно-пластичної задачі про розвиток пластичних шарів для ідеально пружно-пластичної смуги з кутовими точками на її межі. Знайдено довжину пластичних шарів залежно від величини зосередженої сили, прикладеної на

Helicobacter Pylori's Plasticity Zones Are Novel Transposable Elements

PLoS ONE, 2009
يمكن للجينات الموجودة في سلالات معينة فقط من الأنواع البكتيرية أن تؤثر بقوة على الأنماط الظاهرية الخلوية والإمكانات التطورية. تم العثور على جزء واحد بدا غنيًا بشكل خاص بالجينات الخاصة بالسلالة من خلال مقارنة أول جينومين متسلسلين من هيليكوباكتر بيلوري (السلالات 26695 و J99) وسمي "منطقة اللدونة".

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Experimental Study on the Butterfly Shape of the Plastic Zone around a Hole near Rock Failure

Fractal and Fractional
The precursor of rock failure around a hole has always been one of the research hotspots in the field of rock mechanics, and the distribution of the plastic zone is often adopted to reflect the location and form of rock failure.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

Plastic Zone Development During Embankment Construction

Soils and Foundations, 1977
ABSTRACT Rapid stage construction of homogeneous and isotropic embankments is examined. The finite element model constructed assumes an undrained, linearly elastic-perfectly plastic behaviour of the soil. The von-Mises criterion is used to identify when the shear strength is exceeded. The plastic range analysis is based on Yamada et al.

A Termite‐Inspired Alternative to Cement

Advanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Golden‐Ratio–Guided Aperiodic Architected Metamaterials with Simultaneously Enhanced Strength and Toughness

Advanced Functional Materials, EarlyView.
Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...
