graphene, chemical vapor deposition, nickel catalyst, Raman spectroscopy, microscopy

The experimental objective is to determine favorable conditions for growing monolayer graphene via chemical vapor deposition (CVD) on nickel (Ni) substrates for future automotive, aircraft, and body armor applications. Graphene films were grown on 25 μm polycrystalline Ni foil in a 10 cm CVD furnace at temperatures from 900 to … [Read more]

Epidermal growth factor receptor, submicron pillars, contractile units, mechano-sensor, EGFR phosphorylation

Although the epidermal growth factor receptor (EGFR) is known to interact with integrins in the processes of cellular spreading and motility, little is known about the actual role of EGFR. Previous studies from our laboratory have shown that in the early interactions of cells with rigid Arg-Gly-Asp (RGD) ligands, EGFR … [Read more]

IIR filter, microelectrode array, extracellular recording, high density, real-time

As microelectrode arrays (MEAs) with rapidly increasing channel densities are developed to investigate increasingly large ensembles of neurons, the challenges of processing the data in real time has scaled accordingly. For our target 256x256 channel recording system, the data rate of approximately 3 GB/s renders processing schemes considered efficient in … [Read more]

Histone deacetylase (HDACs), autophagy, hypertrophy, pathological cardiac hypertrophy, heart disease

The general medical category of “heart disease” includes many health conditions including hypertension (high blood pressure), myocardial infarction, and heart failure. Collectively, these conditions and many others that fall under heart disease are the leading cause of death in the United States of America. Cardiology research now focuses on mechanisms … [Read more]

diffraction, scattering object, Fourier transform, Python

Although nanotechnology is emerging as a solution to myriad global issues, relatively little is known about the atomic structure of materials at the nanoscale, or nanostructures, at present. The Billinge Group works to utilize comprehensive scattering techniques and advanced computing to “solve the nanostructure problem.” To determine nanostructures experimentally, typically, … [Read more]

General Topic: In order to provide a comprehensive understanding of police-public interactions, the Los Angeles Police Department (LAPD) intends to utilize Body-worn Video (BWV) collected from cameras fastened to their officers. BWV provides a novel means to collect fine-grained information about police-public interactions. Specific Question or Relationship: The purpose of … [Read more]

astrophysics, gamma-ray, instrumentation, telescope

Over the past ten years, the field of very high energy (VHE) astrophysics has developed dramatically, with the number of known sources jumping from 30 in 2005 to over 160 today, as reported by TeVCat. The Cherenkov Telescope Array (CTA) is the next major international project in the field, scheduled … [Read more]

Internet of Things, spectrum scarcity, spectral resources, wireless systems, spectrum occupancy

The phenomenal growth of the use of mobile wireless devices has resulted in a pressing spectrum scarcity. The hunger for more wireless bandwidth is only expected to further increase given new technologies like the “Internet of Things” where machine-to-machine or device-to device communications will put additional demands on the limited … [Read more]

Laser scribing, solar cells, finite element analysis, SnO2:F

Laser scribing is a common method used for manufacturing large-scale solar cells to increase cell efficiency by subdividing large cells into small mini-modules connected in series, decreasing the current produced and therefore reducing the ohmic losses. Introducing large temperature gradients causes thermal expansion and subsequently thermally induced stresses, and these … [Read more]
