Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

open access: yesAdvanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Effect Of Biomass Generated Producer Gas, Methane And Physical Parameters On Producer Gas Fermentations By Clostridium Strain P11

open access: yes, 2009
The effect of producer gas generated by gasification of Kanlow switchgrass was determined to investigate the robustness of Clostridium strain P11 for the integration of gasification-fermentation process in a lab scale.

A geophysical study of a pockmark in the Nyegga region, Norwegian Sea [PDF]

open access: yes, 2008
Over the last decade pockmarks have proven to be important seabed features that provideinformation about fluid flow on continental margins. Their formation and dynamics are stillpoorly constrained due to the lack of proper three dimensional imaging of ...

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

open access: yesAdvanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

On line calorimetry for analysis of producer gas [PDF]

open access: yes, 1999
The purpose of this study is to design and construct an on-line calorimeter for analysis of producer gas with a quick response time. This project explores the use of platinum wire as a catalyst and to measure the temperature difference of a platinum ...

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

open access: yesAdvanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

Producer Gas for Power Generation

open access: yes, 2008
Producer gas is formed by the partial oxidation of a carbonaceous material, such as biomass or coal, in a furnace, generator, or 'producer' unit. This fact sheet outlines the method of doing this, and also other factors to consider like availability of ...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

open access: yesAdvanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Micro gas turbine operation with biomass producer gas

open access: yes, 2007
-We report the performance of a micro gas turbine on biomass producer gas and mixtures of biomass producer gas with natural gas. The micro gas turbine delivers full power on gas mixtures with a heating value of at least 15 MJ/Nm3.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

open access: yesAdvanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.
