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 ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Animal, 2008 In a feeding trial with sheep, four animals each were fed one of the three roughages (perennial ryegrass (PR), meadow fescue (MF) and red clover (RC)) or one of the four different mixtures (g/day 250 : 250 : 250, 375 : 75 : 300, 525 : 187.5 : 37.5 and 75

Nihon Chikusan Gakkaiho, 1996 単方向移動型牛舎における濃厚飼料と粗飼料の給与場所の配置を決定する際の知見を得る目的で,濃厚飼料•粗飼料の分離給与条件下での,両飼料の給与順序が粗飼料採食行動に及ぼす影響を検討した.16頭の搾乳牛をフリーストール牛舎にて群飼し,28日間連続で濃厚飼料および粗飼料の採食時刻および採食量を記録した.濃厚飼料は,1台の個体認識給与機より与え,粗飼料は8台設置した個体認識•採食量自動記録式飼槽より給与した.粗飼料の採食期を,その前後の濃厚飼料採食との関連から,粗飼料の直前•直後に濃厚飼料を無採食(無濃厚粗飼料),濃厚飼料の直後に粗飼料を採食(濃厚後粗飼料),濃厚飼料の直前に粗飼料を採食(濃厚前粗飼料),粗飼料採食期中に濃厚飼料を採食(粗飼料中濃厚)する場合に分類した.各型の採食期の出現頻度 ...

Dairy Cows Vary In Roughage Preferences
, 1953 Limited observations indicate that dairy cows do not all make the same selections when roughages are fed free-choice, and very their consumption when different roughage combinations are available.

Advanced Engineering Materials, EarlyView.This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

An All-Roughage Ration for Bulls
Journal of Dairy Science, 1950 Summary A study has been made of the effects of an all-roughage ration including a high level of silage upon dairy bulls in a controlled experiment for a 12-mo. period. Measurement of the ascorbic acid, total nitrogen and non-protein nitrogen content of semen indicated that there was no observable difference in the levels of these constituents in ...

Assessing Altered Coating Adhesion on Plasma‐Deoxidized Surfaces Under Oxygen‐Free Conditions
Advanced Engineering Materials, EarlyView.This study demonstrates the effectiveness of atmospheric pressure plasma pretreatment in modifying silicon and stainless steel surfaces to improve adhesion. Argon‐hydrogen plasma increases surface roughness and improves adhesion strength, whereas pure argon results in smoother surfaces and structural changes.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.
