The article focuses on Mostafa A. El-Sayed, a chemist and the director of Laser Dynamics Laboratory at Georgia Institute of Technology, who is the recipient of the 2016 Priestley Medal from the American Chemical Society. Topics discussed include the involvement of El-Sayed in studying nanoscale materials, the number of scholarly papers he published the years he spent in academia, and teaching chemistry.

The article offers information on the study that can lead to predictive model and commercializing of gold-driven catalytic processes. It says that gold is chemically inert until it was observed that the presence of nanogold particles have catalytic properties. It mentions the different observations to gold catalyst, in which some shows dependence to the type of support and some independent of any support. It also says that scientist will more likely to uncover what is in the gold properties.

The author explains how his adventure in nanochemistry started in 1969 as a new assistant professor at the University of Toronto. He feels that the nanochemistry needed to achieve pollution control will require new adventurous cross-disciplinary torchbearers to seek out and discover innovative materials solutions. Learning how to exploit the "nano advantage" to enable advances with a high likelihood of widespread use by society is a monumental idea.

A letter to the editor is presented in response to an article on nanosilver toxicity in the August 8, 2011 issue.

The article reports on the technical program highlights of the 237th National Meeting of the American Chemical Society. It mentions the different topics to be discussed at the event which includes "Global Energy Challenges in the 21st Century," "Green Nanoscience," and "Nanostructured Block Copolymer Materials." A keynote address on Nanoscience will also be presented.

The article focuses on the potential of the mechanically interlocked molecules known as molecular shuttles to become components for data storage or nanoscale devices due to their ability to switch between two states.

The article focuses on a study which investigates the interface phenomena of nanoscale intergranular films (IGFs), conducted by Mor Baram, Technion-Israel Institute of Technology researchers along with American Ceramic Society (ACerS) members. Martin Harmer, ACerS member, states that IGFs are stabilized by the interface between grains. He states that the interfaces can explain abnormal grain growth or embrittlement brought by diffusion of impurities into the grain boundaries.

The article offers information on the research team at Pennsylvania State University that works on the development of nanoscale drug delivery carriers for pancreatic cancer treatment. It notes that the survival rate for pancreatic cancer is extremely low while prolonged exposure and repititious regiments may lead to patient debilitation. The researchers have set out to encapsulate the antineoplastic drug and compare its effects in a pancreatic cancer cell line.

The article reports on a direct catalytic route for making nanoscale rings developed by professors Robert H. Grubbs and Jean M. J. Fréchet, postdoctoral Andrew J. Boydston and colleagues of the University of California in Berkeley. The developed catalytic method can be applied in drug delivery or can be used as an organic photovoltaic device. University of Texas professor Grant Willson said the method controls the sequence connectivity of atoms in the formation of molecules.

The article focuses on the oscillation reactions occurring at the nanometer scale. It notes that such oscillations are guided by irregular surface structural features rather than by diffusion, such as in the Belousov-Zhabotinsky oscillating reaction, according to a research by scientists at the Free University of Brussels in Belgium. Information about the findings from the study are presented.

The article focuses on the development of a nanoscale soldering technique made by welding nanowires together. The technique is much like macroscale soldering in which a filler metal is melted to mix metal pieces together. It can fuse objects as small as 10 nanometer and could be used in fabricating nanosensors and nanoelectronics.

The article reports on the new method of obtaining nanoscale images brought by the through-focus-scanning optical microscopy (TSOM) developed by Ravikiran Attota and his associates in the U.S. Relative to this, the researchers mentioned are believed to have used the technique in identifying the potential differences of the nanoscale objects. Furthermore, applications in manufacturing, semiconductor process control, and biotechnology are noted to be potentially obtained in the method.

The article presents findings on a research led by Manfred Buck of the University of St. Andrews in Scotland concerning surface patterning with nanoscale precision. Researchers found that by corralling self-assembled monolayers (SAMs) within the pores of a supramolecular network, a method for creating patterns over large surface areas with nanoscale preciseness is developed. It states that the method could be used to create biosensors or molecular electronics.

The article focuses on a nanoscale chemotherapeutic compound that can kill prostate cancer cells. The compound, as cited, is based on 14-residue helical peptide containing four crown ethers which has the potential to disrupt cell membranes. Information on how to make the compound selective for prostate cancer cells and how it works is provided.

The article reports on the proposal of chemical engineers at Toledo University in Ohio to use iron oxide in the production of hydrogen and in the purification of toxic drinking water. It cites the solar process developed by associate professor Abdul-Majeed Azad to produce hydrogen from iron oxide. The researchers will also examine costs for nano-scaling iron oxide.

The article reports on the development of a fast, reliable environmentally flexible, commercially viable way of creating nanoscale structures by researchers at the Georgia Institute of Technology. The thermochemical nanolithography technique is said to employ the heated tip of an atomic-force microscope to induce a chemical reaction on the surface of a thin polymer film. It adds that the reaction changes the film from a hydrophobic to a hydrophilic substance. It cites that the method can write at speeds of millimeters per second. It can also function outside a vacuum.

The article focuses on the two-dimensional imaging of objects illustrated by the researchers at the Almaden Research Center of International Business Machines Corp. in California. Using magnetic resonance force microscopy, the illustrated objects demonstrate a key advancement of three-dimensional imaging path in the atomic scale. Manager Dan Rugar said that the ultimate goal of the researchers is to conduct a three dimensional imaging of complex structure with atomic resolution.

The article reports on DuPont and Environmental Defense's launch of a tool for evaluating the risks of nanoscale materials. The tool, called the Nano Risk Framework, is intended for use by companies, regulatory agencies, universities and other interested groups around the world. The article also reports on DuPont's plan to launch a titanium dioxide-based light stabilizer for plastics that was tested with the framework.

The article reports on the partnership between Nano-Terra and Merck, through its North American affiliate EMD Chemicals, for the application of nanoscale molecular fabrication methods to the production of specialty chemicals. Physical properties in materials that Merck manufactures and sells will be created in the laboratories of Nano-Terra. The first products from the collaboration are expected to be available in early 2008.
