Research progress on multi-scale damage of rock

Meitan kexue jishu
Rock damage and rupture is a multi-scale chain damage rupture process from microscopic to mesoscopic to macroscopic. It is essential to clarify the damage characteristics of rock at different scales and establish the quantitative relationships of multi ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Characterization of FIB Damage in Silicon

Microscopy and Microanalysis, 1999
Abstract Focused ion beam (FIB) instruments are useful for high spatial resolution milling, deposition, and imaging capabilities. As a result, FIB specimen preparation techniques have been widely accepted within the semiconductor community as a means to rapidly prepare high quality, site-specific specimens for transmission electron ...

Characterization of Damage and Regeneration in Cultured Avian Utricles [PDF]

Journal of the Association for Research in Otolaryngology, 2000
Hair cell regeneration occurs spontaneously throughout life and following hair cell injury in the vestibular epithelia of mature birds and other nonmammalian vertebrates. We examined hair cell regeneration in post-hatch chick utricles that were cultured in media with or without the ototoxin, streptomycin, for various periods.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Acoustic emission characterization of microcracking in laboratory-scale hydraulic fracturing tests

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Understanding microcracking near coalesced fracture generation is critically important for hydrocarbon and geothermal reservoir characterization as well as damage evaluation in civil engineering structures.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Interpreting fatigue tests in hot mix asphalt (HMA) using concepts from viscoelasticity and damage mechanics

Transportes, 2015
The upcoming Brazilian asphalt pavement design method is likely to recommend, in a more basic level, the controlled force indirect tensile fatigue test as a tool for asphalt mixture fatigue characterization.

Characterization of Properties and Damage in Piezoelectrics [PDF]

, 2010
The aim of this chapter is to review the state of the art of the possibilities and existing knowledge on characterization of mechanical and coupling properties and damage detection in piezoelectric ceramics. To address the theoretical problem with a proper rational basis, a review of numerical and experimental techniques to solve the so-called inverse ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
