Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Spore Germination of the Obligate Biotroph Spongospora subterranea: Transcriptome Analysis Reveals Germination Associated Genes

Frontiers in Microbiology, 2021
For soilborne pathogens, germination of the resting or dormant propagule that enables persistence within the soil environment is a key point in pathogenesis.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

First selections of the Hungarian apple breeding program for multiple resistance

International Journal of Horticultural Science, 2004
The aim of the first Hungarian apple breeding program for multiple resistance started in the beginning of the nineties is to widen Hungarian apple assortment by good quality, resistant apple cultivars with excellent productivity and ecological capability

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Powdery Scab of Potato Etiology, its Management through Chemical and Biological Methods [PDF]

Phytopathogenomics and Disease Control
Potato (Solanum tuberosum) production is significantly constrained by powdery scab, caused by Spongospora subterranea f. sp. subterranea (Sss), a soil-borne pathogen that also transmits Potato mop-top virus (PMTV).

Severe incidence of potato powdery scab in Saga Prefecture.

Kyushu Plant Protection Research, 1984
佐賀県上場地域の1983年春作栽培のジャガイモに,Spongospora subterranea (WALL.) LAGERHEIMによるジャガイモ粉状そうか病が発生した。多発ほ場はクロルピクリン消毒を行ったほ場に限られ,なかでも消毒後ビニール被覆を行った部分での発生が激しかった。しかし,同一ほ場内の無消毒部分では極めて発生が少なかった。一方,春作の塊茎肥大前期は乾燥状態が続いたが中期は極めて降雨が多く本病の発生条件によく一致していた。以上のことから、本病の特異的な多発生はクロルピクリン消毒ほ場に罹病種いもが持ち込まれ本病原菌が急激に蔓延し,さらに気象要因も加わったことによるものと考えられる。

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
