What are the Pitfalls of Neglecting Technical Cleanliness Standards? 

Precision manufacturing is a process that emphasizes exact specifications and extremely tight tolerances within fabricated components. Within this domain, the term technical cleanliness (TC) refers to the rigorous control of particulate matter clinging to the surface of parts and products. Though microscopic, these unwanted particles lead to detrimental effects on performance and quality and stand as a formidable challenge in ensuring every component – every finished product – meets the exact standards of cleanliness. 

Electrospinning Applications in Medical Devices

Electrospinning is an emerging technology in the medical device industry, offering precise control over material properties and structure at the nanoscale.

By leveraging electrospinning, medical device manufacturers can tailor materials to meet specific biological and mechanical requirements, resulting in enhanced performance and better patient outcomes. This versatile technique continues to drive innovation, promising new advancements in medical device design and functionality.

In-House or Core Facility SEM: Which Path is Right for You? 

Scanning electron microscopy (SEM) is an essential tool that allows scientists to directly visualize the surface structure and composition of a variety of materials on the nanometer to micrometer scale. The decision between utilizing a core facility for SEM services or investing in an in-house instrument is a critical one that researchers often grapple with. […]

How Much Does a Potentiostat Cost and What Factors Affect the Price?

Potentiostats are all-important tools in electrochemistry that offer precise control of the electrode’s potential and measurement of the current. These instruments play a critical part in electrochemical applications like corrosion testing, wearable electronics, battery research, analysis, and testing for many industries. Potentiostats range from simple handheld single-channel devices to high channel count battery cyclers, and […]

Understanding the Difference between Magnification and Resolution in Scanning Electron Microscopy

Microscopes have revolutionized our ability to observe and analyze the microscopic world with unprecedented detail. By enlarging our view of objects, or magnifying them, microscopes allow us to visualize a greater amount of detail and distinguish (or “resolve”) features separated by very small distances.   The scanning electron microscope (SEM) has quickly become one of the […]

Why is Electrochemical Impedance Spectroscopy (EIS) important in Battery Testing?

Impedance is the frequency-dependent resistance of a circuit or electrochemical system to current flow. Applying a small AC sine wave perturbation to the electrochemical system and measuring the resulting response makes it possible to analyze how the system’s electrical properties vary with different frequencies or timescales. The resulting impedance spectrum provides information about the various electrochemical processes, such as charge transfer reactions, mass transport phenomena, and diffusion processes.

6 Applications of SEM & EDS in Pharmaceutical Sciences

In the evolving landscape of pharmaceutical research and development, the goal to understand the micro and nanoscale properties of therapeutics is vital. Central to this pursuit is the deployment of advanced imaging technologies such as scanning electron microscopy (SEM) – a cornerstone technique implemented across many science and engineering disciplines for morphological and topographical analysis […]

Fabricating “Active” Electrospun Films for Enhanced Food Preservation

Recent advancements in food science research represent a dynamic frontier with profound implications for our global food systems. Breakthroughs in food preservation and packaging technology will contribute to extending shelf life, reducing waste, and increasing safety. Researchers in Dr. Lamin Kassama’s Food Engineering lab at Alabama A&M University are exploring the potential of using electrospun polymers to develop “active” polymeric films for food packaging.

What Probe Liquid Should You Use for Contact Angle Measurements?

Contact angle is defined as the angle formed by a liquid at the three-phase boundary where the liquid, solid, and gas intersect. It gives a fast, quantitative measure of a surface’s wetting properties. These properties can give insight into a solid surface’s interaction with liquids, such as its adhesion with a coating or its biocompatibility with bodily fluids. Contact angle measurements are used in a wide variety of applications, including evaluating surface cleanliness, characterizing functional coatings, and assessing surface treatments.

Thermionic vs. Field Emission Sources: 4 Key Differences

The electron source is one of the most critical components of a scanning electron microscope (SEM) because it determines the quality, brightness, and size of the electron beam used for imaging. The characteristics of the electron beam will influence the overall imaging capabilities of the SEM. Two common types of electron sources used in SEMs […]
