The Department of Physics, Applied Physics, and Astronomy at Rensselaer aims to create a community of students, researchers, staff, and faculty dedicated to providing a collaborative, open, and vibrant environment for the education of undergraduate and graduate students in all areas relevant to modern physics and their relevant connection with current and future societal needs. Enhancement and quenching of single-molecule fluorescence. This mode has a much higher Q than any of the 13 others and so is the mode that will lase when this cavity system is used as the resonator for a VCSEL.

We developed a molecular dynamics method to study this "GRID" process, enabling analysis of both nuclear lifetimes and solid state interatomic potentials. An Y-connection of single wall carbon nanotubes is shown on this STM image. Mn-implanted crystalline Ge was firstly investigated with a relatively high substrate temperature (i.e., from room temperature (RT) to 300°C) to avoid amorphization. This trend is accompanied by a growing challenge for doping processes.

Laser action from two-dimensional distributed feedback in photonic crystals. GaN nanocrystals were imbedded in a poly(methyl methacrylate) thin film matrix (GaN/PMMA) and then studied from structural and optical point of views. Giuseppe Paternò has been awarded the poster prize at the 2014 UK Neutron and Muon Users Meeting, held in Warwick on 10-11 April.

Our main research projects are listed below. Xiaodong Li, "Deformation and Toughening Mechanisms of Natural Biological Nanocomposites – Lessons from Nature," Harbin Institute of Technology, May 13, 2009. A large number of techniques such as High Resolution X-ray Diffraction and Neutron Scattering, Transmission and Scanning Electron Microscopy (TEM and SEM), Scanning Probe Microscopy (SPM), Nuclear Methods and a variety of surface techniques have been used for many years to characterize mostly qualitatively the chemistry and structure of thin films [1-2].

Most wasps are most active in the morning and slow down considerably at midday, when the sun's heat is most oppressive. The LPNS is strongly engaged in education at the undergraduate and graduate levels, including in the management and teaching of the Master of Science programs in Nanotechnology. In other words, is there a size limit that defines the boundary of the nanoworld? Stevce (Stefan) Stefanoski (Major Professor: George S.

Explores the production of musical sound and how it is perceived by us, dealing mainly with the physical basis of sound. Novel Fluorescent Imaging for subcellular microscopy. Grading: Choice between letter grade (A,AB,B,…) or Satisfactory/Unsatisfactory (S/U), to be made at the beginning of the semester. It is also shown that organic 1D nanostructures could behave in a unique way that differentiates them from the isolated molecule or the bulk. Introduction to computational physics, with an emphasis on fields of current research interest in which numerical techniques provide unique physical insight.

Wedge-shaped MgO spacer thickness ranges from 1.5Å to 6Å. This contraction was unexpected since 9-TBAE expands instead. The work, which was published in the prestigious journal Nature Communications [1], advances our current possibilities to image individual molecules on a solid surface using atomic force microscopy (AFM) and scanning tunnelling microscopy (STM).

Xiaodong Li, Dongfeng Diao and Bharat Bhushan, "Fracture Mechanisms of Amorphous Carbon Films in Nanoindentation," Acta Materialia, 45 (1997) 4453-4461. They found that bacterial adhesion and survival rates vary depending on the nanostructure’s shape. PcAFM works in contact mode, using a conductive AFM probe such as gold or platinum-coated silicon tip. Nanotechnology is the construction and use of functional structures designed from atomic or molecular scale with at least one characteristic dimension measured in nanometers.
