Science | Reversible Phase Transition of a Single Nanocluster Witnessed by In Situ TEM from ZEPTOOLS
Precise control over solid-liquid phase transitions at the nanoscale is a central pursuit in materials science. Traditional crystal nucleation theory primarily describes this process as a competition between the reduction in volumetric Gibbs free energy and the penalty of interfacial energy. However, in many natural phenomena and nanomaterial syntheses, phase transitions often occur within geometrically confined spaces, where the interaction between the critical nucleus and the surrounding interfaces fundamentally alters the energy landscape of the transition, significantly affecting phase stability, polymorph selection, and texture formation.

Nature Communications | ZEPTOOLS ZEM Series Desktop Scanning Electron Microscope Aids Development of Highly Stable Fiber-Integrated Graphene Ultrafast Electron Source
In the field of vacuum electronics, stable and durable ultrafast electron sources are critical for achieving high-precision time-resolved imaging and spectroscopic analysis. Traditional electron sources typically rely on metals such as gold and tungsten, or low-dimensional materials such as carbon nanotubes, as photocathodes, generating electron pulses through mechanisms such as multiphoton emission, the photoelectric effect, or optical field emission. However, these methods have significant limitations. On the one hand, multiphoton emission and optical field emission require ultra-high-power lasers or deep ultraviolet pulse excitation, leading not only to cathode material damage and mechanical vibration but also demanding extreme vacuum conditions. On the other hand, existing electron sources generally suffer from time-dependent beam current instability, requiring recalibration every 4–6 hours, which severely constrains equipment operational efficiency and data reliability.

Nature Communications | ZEPTOOLS in situ TEM enables study on controlled motion of polar vortex boundaries in oxide heterostructures
The emergence of ferroelectric topological structures such as ferroelectric polarization vortices and polarization skyrmions in ferroelectric–dielectric superlattices (e.g., (PbTiO₃)ₙ/(SrTiO₃)ₙ, PTO/STO) is an important milestone in contemporary condensed matter physics and materials science. Polarization vortices are characterized by continuous polarization rotation around a vortex core, and their nanoscale size and ultrahigh theoretical storage density make them ideal candidates for next-generation high-density, low-energy-consumption nanoelectronic devices, with the potential to process sub-THz high-frequency signals in an energy-efficient manner. If these topological structures can be controllably manipulated, it is expected to fundamentally transform information storage and computing technologies and provide strong support for the rapid development of fields such as the Internet of Things, artificial intelligence, and large language models.
