Chiral surfaces: accomplishments and challenges.

Chiral surfaces serve as media for enantioselective chemical processes. Their chirality is dictated by atomic- and molecular-level structure, and their enantioselectivity is determined by their enantiospecific interactions with chiral adsorbates. This Perspective describes three types of chiral metal surfaces: those modified by adsorption of chiral molecules, those templated by chiral lattices ...

The Indian Microfinance Experience – Accomplishments and Challenges

Microfinance is gathering momentum to become a major force in India. The self-help group (SHG) model with bank lending to groups of (often) poor women without collateral has become an accepted part of rural finance.

Outcome, measured not only by survival rates but also by the effects of disease and therapy on quality of life, has improved over the past two decades for some tumor types, most notably medulloblastomas. For others, however, there has been little progress, and quality of...
