| Characterization of the Daguerreotype Using the Surface Metrology Instrumental Technique of Confocal Scanning Disk Microscopy |
|
by Patrick Ravines
Surfaces, the two-dimensional outer boundary between the three dimensional object and its environment, have many attributes and are perceived as the complex interplay of three factors: surrounding illumination, surface optical properties such as reflection, and surface geometry or topography. Interest in the characteristics and nature of the surface geometry of photographs is growing in scientific and museum circles. Surface metrology, the measurement of areal features of roughness and waviness from surface textures, is well suited for the study of cultural heritage, historic, and artistic works as a means to characterize their surfaces. Advances in electronics, optics, and faster computing in the past 10 years have revolutionized the field of optical and surface metrology…

X-ray Photoelectron Spectroscopy (XPS) for
Energy-Related Device Characterization |
|
by Richard White and John Wolstenholme
Recent developments in spectrometer design have made the unique capabilities of X-ray photoelectron spectroscopy (XPS) accessible to scientists and engineers working on the latest devices for energy generation and storage in the renewable sector. Because device design and fabrication are reliant on materials engineering on the nanometer scale, it is important that techniques that are able to achieve chemical characterization on this scale are available. The characterization of two such devices will be discussed here: a copper indium gallium (di)selenide (Cu[In,Ga]Se2, CIGS) solar cell and proton-exchange membrane fuel cells, also known as polymer electrolyte membrane fuel cells (PEMFC)…

Quantification of miRNA Expression in Individual Cells
Using a Modified FISH Approach |
|
by Jing Lu and Andrew Tsourkas
Mature microRNAs (miRNAs) are small, noncoding RNA molecules that are typically 18—25 nucleotides in length and are naturally expressed in most living organisms, including mammals. MiRNAs function as post-transcriptional regulators of gene expression by hybridizing to partially complementary messenger RNA (mRNA) and then either triggering RNA cleavage or repressing translation. To date, there have been more than 700 miRNAs identified in
humans, and they have been predicted to influence the regulation of over one-third of all human genes, including transcription factors, oncogenes, and tumor suppressor genes…

| Water Purification System |
 |
The PURELAB® flex handheld water purification system from ELGA Labwater, a Veolia Water Solutions & Technologies company, integrates in-hand monitoring and accurate pure water dispensing in one easy-to-use unit. The flexible handheld dispenser has an easy-to-read digital display that shows both volume and water purity (either resistivity or conductivity and total organic carbon) giving users complete confidence in the water quality and allowing them to visibly monitor the water purity as they are dispensing. The dispense handset has precise fingertip control (like a pipettor) and is intuitive to use; therefore minimal training is required. For maximum versatility, the hand dispenser is height adjustable and the dispense point can be easily positioned to accommodate virtually any size of container.

| In situ Whole-Well Brightfield and Fluorescence Cell Analysis in Microplates |
|
by Fredrik Kamme, Kristi Hohenstein Elliot, Cory Peterson,
Gustaf Angelborg, and Mee Wa Wong
In the era of high-throughput cell biology, experimentation occurs predominantly by executing cell-based assays within microplates. Assays range from routine, such as optimizing transfection conditions and culture conditions, to visualization and analysis of large multicellular structures that better mimic in vivo conditions. The growing number of innovative cellular assays challenges conventional microplate-based cellular analysis systems. There is an increasing requirement to leverage brightfield and multicolor fluorescence capabilities to perform high-throughput morphologic and functional analysis of both living and fixed cells, without the time, cost, and complexity associated with high-content systems. Key constraints include 1) limited utility of transmitted light imaging modes in microplates at the walls of the wells; 2) inability to scan large areas of microplate wells in <30–40 min; and 3) requirement for a dedicated, experienced operator for effective use of complex cellular analysis systems for routine assays…
