In a paper published in Science and Technology of Advanced Materials, researchers summarize recent advances in the controlled synthesis and application of luminescent metal nanoclusters, including potential uses in sensors, bioimaging, and energy harvesting and conversion.

Luminescent metal nanoclusters are a new class of materials consisting of several, to tens of, metal atoms. These materials not only provide the missing link between atomic and nanoparticle behaviors in metals, but also present abundant information for the development of new material systems to meet urgent needs in optical imaging and related areas.

Gold (Au) and silver (Ag) nanoclusters (NCs) have been extensively studied over the past decade. In sharp contrast, other types of nanoclusters -- composed of platinum (Pt) or non-noble metals -- received much less attention, although they demonstrate comparable or superior luminescent properties.

In this paper, published in Science and Technology of Advanced Materials, Hong-Tao Sun and Yoshio Sakka focus on luminescent NCs composed of Pt, molybdenum (Mo), bismuth (Bi) or more than one metal element, and compare their respective advantages and disadvantages. They also speculate on future research and discuss potential developments for their use in sensors, bioimaging, and energy harvesting and conversion.

Given the low-cost, excellent chemical stability, colloidal stability and photostability of the nanoclusters described in this paper, they may find a broad range of applications in optical imaging and related disciplines.

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
