TL;DR: Nanotubes are non‐destructively oxidized along their sidewalls and covalently functionalized with metal nanoparticles via carboxylate chemistry, and individual nanotube reaction products are characterized by atomic force microscopy.
Abstract: Nanotubes are non‐destructively oxidized along their sidewalls and covalently functionalized with metal nanoparticles via carboxylate chemistry. Proteins adsorb individually, strongly and non‐covalently along nanotube lengths. Individual nanotube reaction products are characterized by atomic force microscopy.

TL;DR: In this paper, two classes of two-electron three-centre bonds are discussed and the manner in which the se two types of bonds differ in their interaction with each other is shown.
Abstract: A brief personal account of the relation of the author with Professor Gordon Stone is described. Then the two parts of the scientific presentation of the symposium talk is given. The first part shows that there are two classes of two-electron three-centre bonds. And the manner in which the se two types of bonds differ in their interaction with each other is shown. For example in the Class II 2e-3c bond the central bridging atom formally contributes two electrons to each of the other two atoms, in terms of electron counting considerations. The second part describes how carbon nanotubes, decorated with sugar molecules on the outside and filled with radioactive iodine, sealed in the interior of the SWNTs can be delivered selectively to the lungs of a mouse. The radio nuclei are selectively located in exceptionally high concentrations and this has implications for applications in radio surgery.

TL;DR: Professor Alan Davison used the earliest commercial nuclear magnetic resonance instruments to characterize the then poorly understood transition metal hydrides and also to identify the earliest fluxional organometallic molecules.
Abstract: In 1958 Professor Alan Davison started his research career at an exciting time for the field of organometallic chemistry. New developments in spectroscopy, instrumentation and techniques to manipulate materials in controlled environments to avoid reaction with water or oxygen were becoming widely available. Controlling exposure of an element with highly reactive oxygen facilitated the isolation, characterization and discovery of an abundance of unknown compounds. Alan was an insightful and talented synthetic chemist and made many new and interesting organometallic compounds. He used the earliest commercial nuclear magnetic resonance instruments to characterize the then poorly understood transition metal hydrides and also to identify the earliest fluxional organometallic molecules. In 1970 he entered a collaboration with Professor Alun G. Jones, a nuclear chemist at Harvard Medical School, to characterize and develop the chemistry of technetium. They made a major discovery of technetium molecules which had the ability to selectively locate in human heart muscle, thereby vastly expanding the practice of nuclear medicine to a global community. Professor Alan Davison was also widely known for his outstanding qualities as a teacher and mentor.

TL;DR: In this article, the authors reported the synthesis of abundant single-shell tubes with diameters of about one nanometre, whereas the multi-shell nanotubes are formed on the carbon cathode.
Abstract: CARBON nanotubes1 are expected to have a wide variety of interesting properties. Capillarity in open tubes has already been demonstrated2–5, while predictions regarding their electronic structure6–8 and mechanical strength9 remain to be tested. To examine the properties of these structures, one needs tubes with well defined morphologies, length, thickness and a number of concentric shells; but the normal carbon-arc synthesis10,11 yields a range of tube types. In particular, most calculations have been concerned with single-shell tubes, whereas the carbon-arc synthesis produces almost entirely multi-shell tubes. Here we report the synthesis of abundant single-shell tubes with diameters of about one nanometre. Whereas the multi-shell nanotubes are formed on the carbon cathode, these single-shell tubes grow in the gas phase. Electron diffraction from a single tube allows us to confirm the helical arrangement of carbon hexagons deduced previously for multi-shell tubes1.

TL;DR: Although not yet providing compelling mechanical strength or electrical or thermal conductivities for many applications, CNT yarns and sheets already have promising performance for applications including supercapacitors, actuators, and lightweight electromagnetic shields.
Abstract: Worldwide commercial interest in carbon nanotubes (CNTs) is reflected in a production capacity that presently exceeds several thousand tons per year. Currently, bulk CNT powders are incorporated in diverse commercial products ranging from rechargeable batteries, automotive parts, and sporting goods to boat hulls and water filters. Advances in CNT synthesis, purification, and chemical modification are enabling integration of CNTs in thin-film electronics and large-area coatings. Although not yet providing compelling mechanical strength or electrical or thermal conductivities for many applications, CNT yarns and sheets already have promising performance for applications including supercapacitors, actuators, and lightweight electromagnetic shields.

TL;DR: The features of nanoparticle therapeutics that distinguish them from previous anticancer therapies are highlighted, and how these features provide the potential for therapeutic effects that are not achievable with other modalities are described.
Abstract: Nanoparticles — particles in the size range 1–100 nm — are emerging as a class of therapeutics for cancer. Early clinical results suggest that nanoparticle therapeutics can show enhanced efficacy, while simultaneously reducing side effects, owing to properties such as more targeted localization in tumours and active cellular uptake. Here, we highlight the features of nanoparticle therapeutics that distinguish them from previous anticancer therapies, and describe how these features provide the potential for therapeutic effects that are not achievable with other modalities. While large numbers of preclinical studies have been published, the emphasis here is placed on preclinical and clinical studies that are likely to affect clinical investigations and their implications for advancing the treatment of patients with cancer.
