The germanium-tin (GeSn) alloys comprise a non-equilibrium solid solution of two group IV elements. Their compatibility with integrated circuit processing makes them very useful for monolithic integration on silicon wafers. ...

Cu2ZnSn(S,Se)4 solar cells have achieved the highest efficiency among non-toxic earth-abundant thin film solar materials, however low voltage in solar cell devices caused by band tailing and high levels of poorly understood ...

Metallic nanoparticles (MNPs), which exhibit fascinating optical, electronic and catalytic properties, have been recognized as essential building blocks for the development of advanced nanodevices. Production of MNP ...

Young infants are typically thought to prefer looking at smiling expressions. Although some accounts suggest that the preference is automatic and universal, we hypothesized that it is not rigid and may be influenced by ...

In the latter half of the twentieth century, concurrent with rapid advances in technology and economic globalization, the private sector embraced the concept of strategic planning in order to secure competitive advantage. ...

Anterior cruciate ligament (ACL) injury can substantially alter the life of healthy, active individuals and lead to deleterious long-term consequences. Patients often harbor unrealistic expectations of future knee function ...
