Stochastic Network Growth Simulation for Photopolymerization

Ongoing
We have developed a computational method to simulate the complex interactions of the stochastic processes during polymerization. Specifically, the firing rates of these stochastic events are determined based on monomer information ( e.g. functionalities, rate constants, diffusivities, interaction

Storage Stability of Freeze-Dried Proteins

Strain Measurement for Semiconductor Devices

Ongoing
Mechanical strain is hugely important to semiconductor devices and packages while also being difficult to measure accurately. Strain is engineered into CMOS channels to improve carrier mobility for higher performance at lower power but is also intrinsically present from manufacturing processes where

Strain Measurement for Semiconductor Devices and Packages

Ongoing
Strain is a critical parameter that influences both electrical and mechanical failures of devices, however, measuring strain in complex 3D geometries and vanishingly small feature sizes remains a challenge for manufacturers. Data provided by strain measurements can be used to validate computational

Strategy for extensible, evolving terminology for MGI efforts

Ongoing
Many Indo-European languages utilize a limited set of highly reused, non-synonymous, short semantically relevant words called roots that can be combined to facilitate the building of new compounded terms such as peanut butter and watch dog. This approach, which is more prominent in certain languages

Stroboscopic TEM for Ultrafast Materials Science

Completed
Our people: June Lau co-invented the stroboscopic microscope and had been with this project since inception. She is a physicist, and the PI of this project. She received 2 non-provisional patents for the design of the microscope, and one provisional patent on a specimen holder for microwave delivery

Structural Metrology of Advanced Manufacturing Processes

Ongoing
Understanding material structures in advanced manufacturing is crucial because it enables precise control over material properties, leading to improved performance, efficiency, and cost-effectiveness in production processes. However, this understanding poses many challenges, such as the

Structure-Property Links in Deformation of Materials

Ongoing
The fundamental physics of the deformation process in metals is controlled by crystal plasticity, a type of non-recoverable strain whose evolution depends on the deformation history of the material (as in all plastic processes), and the relative orientation of the applied load and the crystalline

Structure-Property Relationships for High-Strength Materials

Ongoing
The body-armor community generally bases armor design on empirical models that do not directly relate molecular properties to performance. Aramid, aramid copolymers, and polyethylene fibers are highly oriented, anisotropic fibers that require specialized characterization techniques. In addition

Study of Microheterogeneity in Solid Reference Materials

Ongoing
Presently there are a variety of analytical techniques that are served by few or no reference materials due to the small sample sizes they require. NIST currently certifies solid reference materials at or above the 100 mg mass level in most cases with no mention of the effect of using smaller sample

Sub-nanoscale electron microscopy of complex nanostructures

Ongoing
The properties of advance materials are becoming ever more reliant on the ability to manipulate their chemistry and structure at very fine length scales. For example, the relevant feature sizes in state-of-the-art transistors continue to decrease, even as the complexity of the architectures employed
