Steroid Hormone Pathway Mapping

Steroid Hormone Suite Analysis

Ongoing
Steroid hormones are signaling molecules that are major regulators of development, reproduction, stress, and growth. Steroids are synthesized from cholesterol through a series of enzymes, resulting in hormones with distinct biological activities. Although hormones are similar in structure, and...

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

Completed
Intended Impact Work in this project will enable industry to develop rational formulation approaches for freeze-drying, thus facilitating the manufacture safer, longer lasting biopharmaceuticals, with less time and resource cost required for stabilization. Biopharmaceuticals are the fastest growing...

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...
EBSD measurement on 63nm SiGe line

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...

Strategies for Testing Embedded Software

Ongoing
The objective of this project is to develop efficient new testing strategies for devices following a model outside the usual non-software-embedded framework using the concept of Expectation Maximization (EM). The EM approach is attractive because it would provide an efficient method for extending...

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...

Structural Performance for Multi-hazards Program

Ongoing
Objective: To develop and deploy advances in measurement science to enhance the robustness of buildings and infrastructure to natural and manmade hazards. What is the technical idea? The fundamental new idea is that structural robustness can be significantly enhanced by developing reliable...

Structure, Defects, and Scattering in Graphene

Completed
The graphene honeycomb lattice is a key element in determining many of graphene's spectacular properties, which are desirable for a host of electronic applications. The graphene 6-fold symmetric lattice gives rise to charge carriers behaving like light-waves having zero mass. The charge carriers in...

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...

Subspace-Informed Deep Learning Solutions for Nanoscale Microscopy

Ongoing
Cutting-edge nanoscale microscopy techniques such as near-field scanning microwave microscopy (NSMM) and atom probe tomography (APT) enable a multi-dimensional virtual representation of an artifact to be constructed from a set of experimental measurements. These imaging techniques, which are...

Super-Continuum Laser Solar Simulator

Completed
The design of the super-continuum solar simulator is shown below. Light is produced from 450 nm to 2400 nm in sub-nanosecond pulses at a repetition rate of 80 MHz. The total irradiance is sufficient to illuminate a 1 cm 2 cell at more than 1-sun. Initial tests have confirmed that solar cells respond...

Super-resolution optical microscopy

Ongoing
Optical microscopy has been fundamental to science for four centuries, enabling resolution of the microscale. In the last two decades, scientists have made the remarkable discovery that super-resolution methods can extend optical microscopy deep into the nanoscale. It is now possible to detect and...
