How Do Temperature and Humidity Affect Biodegradable Materials
Biodegradable materials can behave differently in a warehouse, a delivery vehicle and the environment where they are eventually discarded. A film that remains usable during dry indoor storage may become softer after exposure to humidity, while a molded item may distort if its temperature rises beyond the range it was designed to withstand. These changes…
How Can Nanocoating Thickness and Adhesion Be Balanced
Nanocoatings can make a surface easier to clean, reduce water wetting, slow corrosion, or improve resistance to contact and abrasion. These functions do not all require the same coating structure. A water-repellent treatment may work through a very thin modification of surface chemistry, whereas a corrosion barrier needs coverage that limits the movement of water…
How Does Particle Size Affect Battery Electrode Performance
A battery’s chemistry is only part of the story. The size of the particles in the positive and negative electrodes also shapes how quickly energy moves during charging and discharging, how much of the active material actually takes part, and how the electrode changes over repeated cycles. Small particles are often linked with short travel…
