Nano 1.2

refNum Software have released Nano 1.2, a majorupdate to their open source C++ framework for developing modernhigh-performance Carbon applications.
Nano 1.2 adds an advanced Software Update engine, built around RSS,that allows users to view release notes, download updates, andupgrade their software from within a running application.
This release also includes over 50 improvements and bug fixes, suchas HTTP support, XML parsing, PCRE-based regular expressions, threadlocks, and additional control over WebKit views.
Daily source code snapshots are now available through Subversion, andthe svn repository can be browsed online.
Nano provides:
o A HIG-compliant application+document model
o C++ wrappers around every HIToolbox view
o Advanced features such as one-line-undo
o Built-in support for Software Update
o Improved Interface Builder experience
Built around the native Carbon framework, Nano allows developers tocreate full-featured, 64-bit clean, Universal Binaries with minimaleffort using the industry-standard C++ language.
More information on Nano is available from the project home page:
(www.refnum.com/products/nano/)
Nano is distributed under the open source BSD licence, and can beused in both commercial and open source projects.

HP researchers tout nanotech in chips:

Hewlett-Packard researchers say their integration of nanotechnology with traditional circuitry designs in computer chips could help reduce energy use and produce ever-smaller devices.Although the development may seem esoteric, scientists believe it could eventually help a wide range of companies — such as automakers, cellphone manufacturers and toy makers — build vastly smaller products that can be reprogrammed and upgraded at any time.

The Latest Nanotechnology Introducing New Nano-R2™

NEW........Nano-R2™

The Nano-R2™ is the latest new product from Pacific Nanotechnology and has many advanced features including dual LCD monitors, advanced image acquisition software and a new 16/32 bit controller architecture.

The Nano-R2™ is compatible with all of the optional features available for the Nano-R™ including a stage heater, environmental cell, and NanoRule+ software.

The Nano-R2™ is innovative, easy to use and thus very productive

Nano Flats

Nanoflat substrates are specially prepared for the attachment/fixing of many sizes and shapes of nanoparticles, in order to image these particle dispersions with an AFM.

The substrates are pre-mounted on standard AFM sample holders.

There are seven Nanoflat substrates and they may be purchased in two formats:

(i) one of each substrate, or (ii) seven of the same substrate.

Molecular Rulers:

A field emission scanning electron microscopy image showing a ~30 nm gold dot formed in the center of a hollow gold parent structure supported on an oxidized Si substrate.

This nanostructure was fabricated by a 'molecular ruler' resist process developed to extend the range of conventional nanolithography techniques.

Molecular Switches:

Perspective views of several molecules inserted into a dodecanethiolate monolayer.

The lower image reveals that several of the molecules have switched OFF. [Imaging conditions: 470 Å x 470 Å; 1.0 pA; Vtip=-1.5 V; Frame interval: 13 hr 20 min]

Self-Assembled Monolayers - Vapor Phase Annealing:


A scanning tunneling microscope image (200nm x 140 nm) of a self-assembled monolayer of n-decanethiolate on Au{111} that has been vapor-annealed in n-dodecanethiolate.

The protrusions on each of the atomic steps are the 1.1 Å higher n-dodecanethiolate molecules.

Self-Assembled Monolayers:

scanning tunneling microscope image (15 nm x 15 nm) of a self-assembled monolayer of n-decanethiolate on Au{111}.

The individual molecules closely pack into a hexagonal array.

Features of the assembly and surface, respectively, including domain boundaries (light blue stripe) and gold vacancy islands (circular blue depressions) are easily seen.

Self-Assembled Monolayers:

Phase separated domains of amide-containing alkanethiolates (yellow) and n-alkanethiolates (red).

Phase separation occurs spontaneously when these components are codeposited from solution based on differing interaction strengths of the two molecules.

Substrate Mediated Interactions

Surface defect sites such as step edges, kinks, and missing atom defects have long been thought to play an important role in chemisorption.

Recent STM measurements of benzene adsorption have yielded real-space observations of the preference for bonding at these sites.

An ordered 2D benzene solid forms along straight Cu{111} steps, as shown in the 4nm x 4nm image above.

One row of benzene molecules is strongly bound below the step riser (labeled row 1) and another above the step riser
(row 2).

The adsorption sites at the interface between the 2D solid and 2D gas phases are transiently occupied by benzene (row 3).

Molecules can diffuse laterally along the interface or can desorb into the 2D molecular gas on the terrace and readsorb, thereby setting up the dynamic equilibrium between the two phases.

Catalysis:


Three STM images of a Ni3 cluster adsorbed on a MoS2 basal plane at 4 K.

All three images show a 60 Å 60 Å area and are plotted as perspective views with the same aspect ratio and angle of view.

The images were acquired with sample biases of +2 (A), +1.4 (B), and -2 V (C) and tunneling currents of 100, 100, and 200 pA, respectively.

The Ni3 clusters effect on the local density of electronic states - both filled and empty can be seen.

PARTICLE CHARACTERIZATION WITH AFM

Atomic Force Microscopy is a very well established technique to characterize surface topography or morphology of individual particles.

AFM particle characterization software packages provide comprehensive tools for analyzing nanoparticles.

The main objective of this paper is to focus on AFM nanoparticle analysis data interpretation.

NANO PARTICLE SAMPLE PREPARATION:

• Scanning Probe Microscopy has been routinely employed as a surface characterization technique for nearly 20 years.

ATOMIC FORCE MICROSCOPY is the most widely used subset of SPM, which can be used in ambient conditions with minimum sample preparation.
