Applications for Electrical Stages Range to be Presented at the 2017 European Materials Research Society Meeting in Warsaw
Linkam will be show-casing materials characterisation products at the annual Fall meeting of the European Materials Research Society. This year, it will be held at the Warsaw University of Technology. The exhibition will run from 18th - 20th September.
Linkam have been creating sample characterisation solutions for the microelectronics and semiconductor field for many years. They design stages with accurate temperature control ranging from -196°C to 1500°C. The environment within the chamber can also be controlled, with the options of gas purging, controlled vacuum or humidity. To accommodate for electrical measurements, stages can also be fitted with a variety of electrical output connectors and gold tipped tungsten needle probes.
The accurate temperature control and ability to combine with other analytical techniques such as Raman microscopy makes Linkam stages ideal for the study of perovskites and 2D materials. A group in the Technical University of Denmark used a custom-built probe stage to test the suitability of 2D materials as protective coatings for metals. The Linkam stage was used to simulate both a short and long-term heated oxidative environment in which the samples were placed. The quartz window of the stage allowed the users to follow the oxidation process through Raman microscopy.
The Linkam probe stage, the HFS600E-PB4, was used by a team from the Nanyang Technological University and Trinity College Dublin to study angular momentum states of perovskite materials. The set-up was ideal for performing low temperature Raman spectroscopy whilst probing the decay of angular momentum states. Another group in the Sichuan Normal University, China, synthesised a new lead-free perovskite while using the high temperature electrical stage, the TS1500E, to test the permittivity of the ceramic.
These stages have also been used in many cutting-edge fields of science including liquid crystals, thin film research and photovoltaics.

43759pr@reply-direct.com Hyperspectral Imaging of Gold Nanoparticles in Live Blood Cells
The circulatory system is a vehicle for delivery of functionalised nanoparticles to targeted cells and tissues. The CytoViva Enhanced Darkfield Hyperspectral Microscope from Schaefer Technologie GmbH is a highly effective tool for optically imaging and spectrally characterising nanoparticles while in the bloodstream or in other complex environments. No fluorescent labelling or other sample preparation of the nanoparticles or the biological matrix is required when using this technique.
The microscope creates high signal-to-noise optical and hyperspectral images, which enable fast and direct observation of unlabelled gold nanoparticles in live blood cells (see in the figure). The hyperspectral images contain one full spectrum of the reflected light in each pixel of the image. This makes it easy to identify
the spectral response of the nanoparticles, confirming their presence, and the way they interact with individual cells of the blood sample. It can also provide keen insight regarding the chemical stability of nanoparticles and their drug load or other surface functionalisation. Therefore, the CytoViva technology can help you to understand the nanoparticle efficacy when used as drug delivery vectors.
Please contact Schaefer Technologie GmbH to learn more about this imaging technology or to arrange for test imaging of your samples.

Olympus has launched two new microscopes optimised for long periods of routine observation. In the design of the CX43 and CX33 microscopes, frequently-used controls have been lowered, allowing a more natural position for the user’s arms during operation.
In both the CX43 and the CX33, the stage is 70 mm lower than the previous model, resulting in a large working space under the eyepiece that makes it easier to check or swap samples with just one hand. The stage and co-axial focus knobs have also been lowered, so users can reach these controls while their forearms remain on the desk. The low-positioned revolving nosepiece with finger rest accommodates up to five objectives and enables users to quickly change magnification with minimal arm movement.
A centring-free LED light source with a long 60,000-hour lifetime has been added, ensuring a stable imaging performance over long periods of time. The new LED light source provides uniform illumination and constant colour temperature at any brightness level. This means that users get natural colour representation from a wide range of stains and can carry out analyses faster and with more confidence.
In addition, the universal condenser on the CX43 microscope supports objectives ranging from 2X to 100X magnification and covers a variety of observation methods—including phase contrast and fluorescence—giving users the flexibility to switch to the appropriate method for their applications on a single microscope frame. The CX33 microscope has a built-in camera port and the CX43 microscope has an optional trinocular observation head for digital imaging.
