Investigation of Thermo‐Chemical Processes in Commercial MgO‐C Refractory Bricks With and Without MgO‐C Recyclate at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

Entrepreneurship and Inclusive Growth in South Africa, Zimbabwe and Mozambique [PDF]

open access: yes, 2015
While increasing attention is being paid to the drivers and forms of entrepreneurship in informal economies, much less of this policy and research focus is directed at understanding the links between mobility and informality.

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced 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 ...

The Impact of China’s Labor Contract Law on Workers [PDF]

open access: yes, 2010
ILRF\u27s report examines the impact of the Labor Contract Law on workplaces in China’s export manufacturing hubs. ILRF argues for various strategies, from a greater emphasis on collective bargaining to community-based legal education, to ensure full ...

Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

open access: yesAdvanced 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.

Space construction in media reporting: A study of the migrant space in the 'Jungles' of Calais [PDF]

open access: yes, 2015
Media are intrinsically implicated in constructing and framing space as well as in the imagination of communities. This paper examines how media through the spatial construct of the ‘jungle’ premises the discourses of migration between the borders of UK ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

International Migration, Human Capital, and Entrepreneurship: Evidence from Philippine Migrants’ Exchange Rate Shocks [PDF]

open access: yes
Millions of households in developing countries receive financial support from family members working overseas. How do the economic prospects of overseas migrants affect origin-household investments—in particular, in child human capital and household ...
