Molecular Dynamics of Self-Assembled Monolayer Formation in Soft Nanolithgoraphy

Heo D., Yang M., Jang J., Pusan National University, KR

Molecular dynamics simulation is performed to study the growth mechanism of self-assembled monolayer in the AFM tip-assisted soft nanolithography such as in dip-pen nanolithography [1]. We investigate how the droplet created around the tip spreads [...]

Raman study and DFT calculations of amino acids

Sonois V., Estève A., Zwick A., Faller P., Bacsa W., CEMES CNRS Univ Toulouse, FR

Previously we reported intense and narrow vibrational Raman bands of the amino acid histidine grown from droplets of aqueous histidine on silica (Sonois et al., 2007, Chem. Phys. Lett., 439, 360-363). In the present communication [...]

Conformational Changes of Acetylcholine During Spontaneous Diffusion Through a Nano/Microporous Gel: Towards a Novel Approach to Biomolecular Hardware

Vaganova E., Yitzchaik S., Ovadia H., Lyshevski S.E., Khodorkovsky V., Pierola I.F., The Hebrew University, IL

This paper reports the results which intent to enhance the understanding of mechanisms and transitions taking place in biological systems. In order to mimic these low energy processes in natural systems, as well as to [...]

Nanoporous Alumina Membranes Based Microdevices for Ultrasensitive Protein Detection

Bothara M.G., Reddy R.K., Barrett T., Carruthers J., Prasad S., Portland State University, US

This research focuses on using the electrical and chemical properties of nanoporous alumina membranes to improve the sensitivity and performance of Si-based microdevices for protein sensing. The integration of nanoporous membranes with the microdevice results [...]

Lithium selective adsorption on low-dimensional TiO2 nanoribbons

Zhang Q-H, Li S-P, Sun S-Y, Yin X-S, Yu J-G, East China University of Science and Technology, CN

Low-dimensional TiO2-related nanomaterial with high morphology specificity, including nano-tube, -wire, -sheet, -fiber and -ribbon, had attracted particular interest in advanced applications as catalyst, solar-energy conversion semiconductor, gas sensor and electrochemical material, as it was discovered [...]

Interaction of Polyamido-amine (PAMAM) nanoparticles with the glassy carbon supported bilayer lipid membrane

Jadhav S.R., Mark Worden R., Michigan State University, US

Polyamido-amine (PAMAM) dendrimers are hyperbranched polymers with uniform particle size making them ideal monodisperse nanoparticles. PAMAM dendrimers are being pursued as non-viral vectors for gene delivery due to their low immunogenicity and their ability to [...]

Permeability and protein separations: functional studies of porous nanocrystalline silicon membranes

Snyder J., Kavalenka M., Fang D., Striemer C., Fauchet P., McGrath J., University of Rochester, US

We have developed an ultrathin (15nm) freestanding nanoporous silicon based membrane [1]. This new material, termed porous nanocrystalline silicon (pnc-Si), is fabricated using standard photolithography techniques. Pore sizes can be tuned in a thermodynamically driven [...]

Design and Parameters of Cellulose Filter Media with Polymer Nanofiber Layer

Maly M., Petrik S., ELMARCO s.r.o., CZ

Nanofiber polymer layer deposited on regular cellulose filter media usually shifts resulting air filtration parameters of this material several classes higher. Very fine nanofiber web of basis weight of 0.01 gm-2 to 0.1 gm-2 improves [...]

Towards Automation in the Characterization of Nanostructured Materials and Devices

Weishaupt K., Schmidt U., Dieing T., Hollricher O., WITec GmbH, DE

The characterization of nanostructured materials implies knowledge about their chemical and structural properties, leading to a growing demand for characterization methods for heterogeneous materials on the nanometer scale. However, certain properties are difficult to study [...]
