Millet bread and pulse dough from Early Iron Age South India

Prof. Jennifer Bates and her coworkers, Kelly Wilcox Black and Prof. Kathleen Morrison, published a new archaeobotanical article, "Millet Bread and Pulse Dough from Early Iron Age South India: Charred Food Lumps as Culinary ...

Collective circular dichroism by chiral plasmonic nanoparticles

Molecular chirality refers to the geometrical property of molecules with broken mirror symmetry. Characterizing molecular chirality and understanding their roles in physiochemical situations has been important in broad research ...

A new all-2-D light-emitting field-effect transistor

Transition metal dichalcogenides (TMDs), a two-dimensional (2-D) semiconductor, are promising materials for next-generation optoelectronic devices. They can emit strong light due to the large binding energies of excitons, ...
