Simple dynamics underlying the survival behaviors of ciliates

open access: yesBiophysics and Physicobiology, 2022
Ciliates are swimming microorganisms in aquatic environments. Habitats where ciliates accumulate include nutrient-rich solid–liquid interfaces such as pond bottom walls and waterweed surfaces. The ciliates stay near the walls to survive.

Expression of sugarcane COBRA-Like genes, ScBC1 and ScBC1L2, increases plant biomass

open access: yesBMC Plant Biology
Background Cellulose is a major determinant of plant biomass yield and quality, with significant industrial relevance. COBRA proteins are established regulators of cellulose deposition and cell wall organization; however, their roles in sugarcane ...

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Growth of intraperitoneally transplanted ascites hepatoma, AH39 cells, in the area of gelatin sponge inoculation into the abdominal wall of Donryu rats.

open access: yesGan, 1979
A piece of gelatin sponge was inoculated submesothelialy in the abdominal wall of female Donryu rats, and 1, 2, 4, 7, 14, or 21 days later, 1 x 10(5) cells of ascites hepatoma AH39 were intraperitoneally transplanted. Tumor cells were detected in the area of gelatin sponge inoculation in each group 2 to 5 days after the transplantation.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Energy Absorption Characteristics of Honeycomb Structure of Nanofluidic Packer Rubber Under Coplanar Compression

open access: yesShiyou jixie, 2022
The nanofluidic packer rubber is a nanofluidic system coated by honeycomb structure.Its ultrahigh efficiency of energy absorption helps to absorb the pressure fluctuation during the explosion of perforation charges and reduce the risk of rubber seal ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Comparative studies on stem anatomical structure of rice plants with various ploidy level

open access: yes浙江大学学报. 农业与生命科学版, 2009
To investigate the effects of ploidy changes on the stem structure, by using flow cytometry (FCM), we distinguished six different ploidy materials (haploid, diploid, and triploid of line FC311 and haploid, diploid, and tetraploid of line FC322), in rice (
