Physical characterization of morphologically diverse colour maize (Zea mays) seeds

The Indian Journal of Agricultural Sciences, 2023
The manual seeding, harvesting and processing operations are the most labour intensive and the current practices have many drawbacks. The physical properties of seeds play an important role for designing or fabricating tools or devices which are meant ...

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

Advanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

The Bounded Diameter Conjecture and Sharp Geometric Estimates for Mean Curvature Flow

We show that the intrinsic diameter of mean curvature flow in $\mathbb{R}^3$ is uniformly bounded as one approaches the first singular time $T$. This confirms the bounded diameter conjecture of Haslhofer. In addition, we establish several sharp quantitative estimates: the second fundamental form $A$ has uniformly bounded $L^1$-norm on each time slice, $

Geometric properties of Kohanz apple fruits [PDF]

, 2012
Kohanz is a domestic apple variety which is grown in Iran.  It is sensitive to packing conditions.  Bad packages normally cause decline in its quality.  Therefore, apple's geometric properties are of important consideration in the design of the fruit's ...

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

A new method for the calculation of the mean diameter of soil aggregates [PDF]

, 1997
Ao calcular o diâmetro médio ponderado (DMP) ou o diâmetro médio geométrico (DMG) de uma amostra de solo, ponderam-se o diâmetro médio aritmético (no caso do DMP) ou o logarítmico (no caso do DMG) de cada classe pela massa de agregados nela retida.

Effect of Posture Change on the Geometric Features of the Healthy Carotid Bifurcation [PDF]

, 2011
Segmented cross-sectional MRI images were used to construct 3-D virtual models of the carotid bifurcation in ten healthy volunteers. Geometric features, such as bifurcation angle, internal carotid artery (ICA) angle, planarity angle, asymmetry angle ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
