Adhesive Properties of Fibrinogen Matrices

Fibrinogen (Fg):

- Fg is a high abundance protein in blood.

- Fg plays key role in the process of normal wound

healing as well as pathogenic thrombus formation.

- The adhesion of leukocytes and platelets on

implanted vascular grafts is known to trigger an

undesirable inflammatory and prothrombotic response.

How does circulating fibrinogen alters adhesive

properties of surfaces? Mechanism?

Goal: Control of thrombus formation and

thrombogenicity of implanted materials

Thermionic Energy Conversion – Space Charge Effects

Space Charge limits current and energy conversion efficiencies

Traditional approaches: employ Cs vapor to neutralize vacuum space charge

and lower the emitter and collector work function.

Nanotechnology Approaches:

1) <10 µm emitter - collector spacing

2) Nanoscale vacuum emitters

Current topics: Accelerated 4+1 degrees

• BS Physics-PSM in Nanoscience submitted January 2011, implemented for Fall 2011; 2 students on course in 2011-12

• BSE Materials-PSM in Nanoscience submitted January 2012, agreed for Fall 2012; recruit both Seniors and Juniors now

• BS Chemistry-PSM in Nanoscience discussed since March 2011

PSM-Nanoscience Admission

• Bachelor’s degree in physics, chemistry,

materials, engineering or related field

• Official ASU Graduate Application

• Official transcripts of all undergraduate and

graduate coursework

• Statement of purpose outlining research

interests and reasons for applying

• 2 letters of recommendation

• Graduate College Admission Criteria

4+1 BS + PSM Details

• Both degrees in 5 years

Advantages of 4+1 scheme

• Attracting highly performing undergraduates who intend to work in industry (or other external organizations)

• Improving the quality of the educational experience for B.S. students

• This accelerated program will increase the total number of graduate students while decreasing the time-to-degree

PSM-Nanoscience 3+2 Admission

ASU

• The 2 years at ASU is similar to the last two

years of the 4+1 program

PSM program funding

• Wiche/WRGP: scheme is very important for students from Western States (out of state students at in-state fees)

• Program Fees: for new students from Spring 2012: $500/semester Full-time and $250/semester. $500 per project payable to Project Advisors. Allocation may increase once program fees are returned to the program
