Gibbs Free Energy

One of the challenges of using the second law of thermodynamics to determine if a process is spontaneous is that it requires measurements of the entropy change for the system and the entropy change for the surroundings. An alternative approach involving a new thermodynamic property defined in terms of system properties only was introduced in the late nineteenth century by American mathematician Josiah Willard Gibbs. This new property is called the Gibbs free energy (G) (or simply the free...

This workflow enables lamella production targeting fluorescently labeled biological structures that are small (<1 μm in axial extent) and rare (1 copy per cell) using a cryogenic tri-coincident imaging platform. This platform integrates fluorescence microscopy, focused ion beam milling, and scanning electron microscopy at a single focal position and enables simultaneous fluorescence microscopy while milling.

This video demonstrates the process of generating neuron balls using a hanging drop culture technique. Within the hanging drops, cells move towards the bottom, self-assembled into three-dimensional structures forming neuron balls, which can be used for neurobiological studies.
FAQs
Each collision can impose localized mechanical energy on powder particles. Impact promotes plastic deformation, while friction and repeated contact can encourage cold welding. Continued processing then drives welded regions to fracture and become finer. The balance between welding and fracture determines whether particles mainly consolidate, refine, or mix, which directly affects powder uniformity and subsequent material development.
These parameters control the intensity and cumulative effect of ball-powder interactions. Milling speed affects collision activity, duration determines how long deformation, welding, fracture, and refinement continue, and the ball-to-powder ratio changes the relative amount of milling media available for impacts. Adjusting them helps researchers tailor grain size, phase formation, and material properties.
The milling atmosphere is one of the controllable conditions that influences phase formation and the resulting material properties. Maintaining a selected atmosphere allows researchers to study or promote desired solid-state changes while processing the powder. This control is especially relevant when engineering advanced materials whose final behavior depends on composition, structure, and phase development.
Particle refinement is only one possible outcome of the process. Mechanical alloying uses the same repeated deformation, cold welding, and fracturing events to mix or combine solid constituents and support phase formation without melting the feedstock. Consequently, the method can serve both as a size-reduction approach and as a route for developing compositionally modified engineering powders.
A typical workflow places the selected powder and milling balls in a rotating or oscillating mill, then applies controlled processing conditions. Researchers set the milling speed, duration, ball-to-powder ratio, and atmosphere according to the intended result. After processing, they evaluate whether the powder shows the targeted refinement, mixing, phase formation, or property changes.
High Energy Ball Milling supports the development of nanostructured metals, ceramics, composites, and other advanced powders. Engineering researchers can use it for mechanical alloying, solid-state phase development, and particle refinement when melting the feedstock is undesirable. The resulting powders provide a basis for tailoring grain size and material properties during materials research and manufacturing development.
