7 Reasons to Use Electrospraying as a Reproducible Method to Generate Nanoparticles
Particles are used daily in a wide variety of applications including coating surfaces and encapsulation of active ingredients. Coating surfaces can impart additional functionality and modulate the mechanical properties of the surface. Encapsulation of active pharmaceutical ingredients (APIs) is an effective method of delivering drugs to the site of action, especially water-insoluble drugs. Encapsulation of […]
Role of Cyclic Voltammetry in Li-Ion Battery Materials Research
Cyclic voltammetry (CV) is one of the most popular techniques used for electrochemistry experiments and is commonly used to study oxidative and reductive processes. This technique involves measuring the current that is generated during the redox process when the voltage is varied between the electrodes. CV can be used to assess the redox properties, charge-discharge […]

Desktop STEM as a Sample Screening Tool for Cryo-EM
Sample preparation for cryogenic electron microscopy (cryo-EM) can be a demanding and expensive process, requiring several rounds of purification and screening to isolate the macromolecules of interest. Negative stain electron microscopy (EM) is one of the established tools for the initial screening of purified samples, specifically for assessment of particle size, morphology, concentration, and agglomeration. […]
How does Surface Roughness Affect Contact Angle Measurements?
Contact angle measurements with an optical tensiometer can be quick, non-destructive, and straightforward measurements to characterize surface chemistry and understand the interaction of a surface with a liquid of interest. Young’s equation (Figure 1A) defines the measured contact angle as a function of the surface tension of the liquid, the surface energy of the solid, […]
Empowering Nanofibers: Enhancing Usability and Overcoming Production Challenges
Nanofibers, or fibers with diameters on the scale of 10-9 meters, exhibit unique properties, differing significantly from the properties of the bulk materials. These include a large surface area to volume ratio, high porosity, high encapsulation efficiency, superior mechanical properties, and higher chemical stability. As a result of these remarkable properties, some versatile materials have found their way into a multitude of applications with the potential to address critical challenges in numerous fields and lead to a more sustainable and technologically advanced future.

7 Recent Advancements in Nanofiber Applications
Nanofibers are ultrafine fibers with diameters typically ranging from a few nanometers (nm) to a few hundred nanometers. To put this in perspective, a nanometer is one billionth of a meter, and the width of a human hair is about 80,000 nm. Super small!
The Role of SEM in the Medical Device Industry
Implantable medical devices are continually pushing the boundaries of what is possible when modern medicine and engineering join forces. An implantable medical device is an instrument that is surgically inserted into a patient’s body to restore or enhance function to diseased or injured parts of the body. Common examples include pacemakers for correcting heart arrhythmia, […]
