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

open access: yesAdvanced 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

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

open access: yesAdvanced 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.

Therapeutic and psychosocial interventions in the treatment of alcohol-dependent patients : findings from clinical research [PDF]

open access: yes, 2013
Alcoholism is a chronic and severe disease that impairs life-quality and causes problems in health, in psychological, and in social issues over time. In the past very few treatment services were available for alcoholism.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

open access: yesAdvanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Catalytic Synthesis of Higher Alcohols

open access: yes, 2016
This thesis deals with the synthesis of higher alcohols using modified Cu/ZnO catalysts. The rate-limiting step for this type of catalyst is regarded as C1 to C2 chain growth step. Therefore the strategy was to mix ethanol with the synthesis gas, in order to propagate the chain growth from this step. Screening of parameters is both batch and continuous-

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

open access: yesAdvanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Awareness of, and participation with, user-created alcohol promotion, and the association with higher-risk drinking in young adults

open access: yesCyberpsychology: Journal of Psychosocial Research on Cyberpspace, 2017
User-created alcohol promotion refers to the content distributed through new media which intends to promote consumption, but independent of commercial digital marketing.

The Preparation of Unsaturated Higher Alcohol

open access: yesJournal of Japan Oil Chemists' Society, 1964
A number of preparation methods of unsaturated higher alcohol have been reported, but the production of unsaturated higher alcohol on an industrial scale by these methods has not been susceeded in Japan.In this report, the authors report the results of a new method using the combined catalyst Cu-Cr-O and cadmium soap.
