Investigation of Oxide Dispersion Strengthening Effect on the Strength of Diffusion‐Bonded AISI304 Parts

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

Toward Maximum Utilization of Heavy Rare Earths in Sintered Nd–Fe–B Magnets by Grain Boundary Diffusion Source and Application Area Optimization

open access: yesAdvanced Engineering Materials, EarlyView.
In this work, the grain boundary diffusion process is optimized to maximize heavy rare earth utilization by strategic magnetic hardening of areas in the magnet such as corners or edges that are highly susceptible to demagnetization, as demonstrated by finite element magnetostatics simulation on an internal permanent magnet, synchronous traction motor ...

Temporal Variability of the X-ray Emission of the Crab Nebula Torus [PDF]

open access: yes, 1998
We have analyzed five ROSAT HRI images of the Crab Nebula spanning the years 1991 to 1997 and have found significant changes in the emission structure of the X-ray torus surrounding the pulsar. Certain regions increase in brightness by about 20% over the

An Analysis of 510 Strains ofCorynebacterium Diphtheriae [PDF]

open access: yesEpidemiology and Infection, 1933
Since Anderson, Happold, McLeod and Thomson (1931) described their division of the varieties ofCorynebacterium diphtheriaeinto three groups—gravis, intermediate andmitis—and submitted correlations with clinical types of diphtheria, several workers have published results of investigations which, for the most part, are against such a hard and fast ...

On the Investigation of a Sustainable Two Step Laser‐Based Surface Treatment for the Functionalization of Additive Manufactured Ti–6Al–4V Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study developed a two‐step laser‐based process for sustainable surface treatment of Ti–6Al–4 V components, combining laser polishing and direct laser interference patterning with ns and ps pulses. Key findings include significant roughness reduction, hierarchical patterning with ps pulses, and improved homogeneity. A cost function is developed for

Adaptation of the PESTonFARM Model to Support Decision-Making and Planning of Local Implementation of the Sterile Insect Technique in the Control of Ceratitis capitata Flies (Diptera: Tephritidae)

open access: yesApplied Sciences
The Sterile Insect Technique (SIT) is most effective at large regional scales when applied within an area-wide framework. However, there is a need to investigate its feasibility at smaller scales, e.g., for emergency responses to local fruit fly ...

Decoupling Economic Growth from Fossil Fuel Use—Evidence from 141 Countries in the 25-Year Perspective

open access: yesEnergies, 2020
This study offers an in-depth analysis of the decoupling of economic growth from fossil fuel use in 141 countries over the last 25 years. The study is based on the Tapio decoupling approach, and two methods of measuring fossil fuel use, i.e., domestic ...
