NSF Interfacial Processes and Thermodynamics (IPT) Program (PD 13-1414) - FAQs

1) What is the NSF Interfacial Processes and Thermodynamics (IPT) program?

The NSF IPT program (PD 13-1414) funds fundamental engineering research centered on three closely related scientific pillars: interfacial phenomena, mass transport phenomena, and molecular thermodynamics. A key focus is understanding and engineering what happens at interfaces, where molecular behavior can differ dramatically from bulk behavior and where many modern technologies are built.

2) What research topics does IPT prioritize?

IPT prioritizes fundamental work that explains, predicts, and ultimately helps engineers control how interfaces form, evolve, and govern transport. The program emphasizes research that connects molecular-scale interactions and design to measurable macroscopic outcomes (for example, mass transfer rates, interfacial stability, phase behavior, and thermodynamic properties) under realistic conditions.

3) What are the three scientific pillars explicitly mentioned by the program?

The program is organized around: (1) interfacial phenomena, (2) mass transport phenomena, and (3) molecular thermodynamics.

4) Why are interfaces such a central focus for this program?

IPT highlights that molecule behavior at interfaces can be very different from the bulk, and many modern technologies rely on engineered interfaces. Because interfaces can control assembly, stability, transport, and function, understanding interfacial physics and chemistry at the molecular level can be decisive for engineering outcomes.

5) What is a current priority area for IPT?

A stated current priority is molecular engineering at interfaces for nanoprocessing of soft materials. Proposals are expected to connect molecular-scale design and interfacial physics to how soft materials can be assembled, patterned, or functionalized at micro- and nano-length scales.

6) What kinds of molecules are relevant to IPT-supported research?

The program description emphasizes molecules that sit at interfaces and provide specific functional interfacial properties. Examples mentioned include polymers, surfactants, and specialized biomolecules, particularly when relevant to nanofabrication and emerging micro/nano technologies.

7) Does IPT support research on self-assembly and templating at interfaces?

Yes. The program highlights that interfacial materials often form through self-directed processes such as templating and molecular assembly, largely driven by thermodynamic intermolecular forces.

8) Are real-world effects like flow and electric fields within scope?

Yes. IPT recognizes that real interfacial systems can be influenced by fluid flow and electric fields, and it notes that interfacial formation or function may involve weak chemical reactions in some cases.

9) What methods and approaches does IPT encourage?

IPT encourages theory development and advanced molecular simulation, ideally paired with experimental validation when feasible. The program supports work that develops or uses modeling/simulation methods to predict transport and thermodynamic properties of fluids and complex mixtures in interface-dominated environments.

10) What kinds of systems and environments are specifically called out?

Examples explicitly mentioned include membranes, two-phase mixtures, nanoconfined systems, and biologically relevant fluids containing complex molecules. The solicitation also emphasizes that many target systems involve polymers and surfactants, along with biomolecules that bring biofunctionality into interfacial design.

11) What types of outcomes or measurable behaviors should strong proposals connect to?

Strong proposals typically link molecular-scale interactions to measurable macroscopic behavior such as mass transfer rates, interfacial stability, phase behavior, or thermodynamic properties under realistic conditions.

12) What longer-term application areas does IPT mention as potential beneficiaries?

The program frames its fundamental research goals around enabling outcomes that could ultimately support more economical and environmentally benign processing, improved water quality, and novel functional materials, including sensor materials for industrial, environmental, and biomedical use.

13) How important is nanotechnology to this program?

Nanotechnology is described as a critical enabling component across the program's motivating outcomes. This signals that proposals connecting interfacial science to nanoscale structure, fabrication, and function are especially aligned with IPT.

14) Does IPT coordinate with other NSF programs?

Yes. IPT notes active coordination and potential joint support with other NSF programs within and outside the CBET Division, including participation in nano- and cyber-related activities.

15) Is biosensing within scope for IPT?

Yes. A specific cross-cutting interest area mentioned is biosensing. IPT is interested in materials for new biosensing systems and may jointly support projects with the Biosensing program, particularly those involving molecular-level surface functionalization.

16) Are collaboration mechanisms like GOALI encouraged?

Yes. The program encourages common NSF collaboration pathways such as undergraduate research involvement, industry-university partnerships through GOALI, and international collaboration.

17) What is the typical award duration for unsolicited research awards?

Unsolicited research awards are typically one to three years in duration.

18) What is the typical award size?

The average annual award size is about $90,000.

19) What happens if a proposal budget is substantially higher than the typical amount?

The program explicitly warns that proposals requesting substantially more than the approximately $90,000 average annual award size, without prior discussion with the Program Director, may be returned without review. Budget sizing and early communication are emphasized.

20) Does IPT consider small equipment proposals?

Yes. Small equipment proposals up to $70,000 are considered during the annual submission window.

21) What should applicants do if their idea may be outside the program scope?

The solicitation recommends contacting the Program Director before submitting proposals that may be viewed as outside the listed emphasis areas, to reduce the risk that the proposal is returned without review.

22) What does IPT expect regarding novelty or transformative potential?

Like most CBET programs, IPT expects proposals to clearly explain what is novel or potentially transformative compared to prior work and why the work matters for engineering science, along with plausible longer-term societal and/or industrial impacts if successful. The solicitation emphasizes that the novelty/transformative angle should appear at minimum in the Project Summary, not only later in the narrative.

23) What factors influence funding decisions beyond peer review?

The program notes that funding decisions depend not only on reviews but also on portfolio balance across subfields, overlap with other funding sources, total available program funds, and broader NSF priorities and policies.

24) Are CAREER proposals encouraged under IPT?

Yes. CAREER proposals are strongly encouraged. The solicitation references the standard five-year CAREER duration and notes that an engineering CAREER deadline is typically in July.

25) Does IPT consider conference or workshop proposals?

Yes. The program considers conference/workshop proposals.

26) Are NSF special mechanisms like RAPID and EAGER available?

Yes. The program considers NSF special mechanisms like RAPID and EAGER, but these typically require a conversation with the Program Director before submission.

27) Is cost sharing required?

No. The archived listing indicates there is no cost-sharing requirement.

28) What is the CFDA number for this opportunity?

This NSF discretionary grant program is listed under CFDA 47.041 (Engineering Grants).

29) Who is eligible to apply?

The archived listing states eligibility is unrestricted.

30) What were the estimated total funding and number of expected awards in the archived listing?

At the time of the posting, estimated total funding was $7.4 million with an expected 67 awards.

31) Is there an award floor listed?

Yes. The archived listing shows an award floor of $240,000, while also describing typical research awards separately as averaging about $90,000 per year (often implying multi-year totals in that general range).

32) When can proposals be submitted?

The solicitation operated with an annual submission window (historically mid-August through mid-September).

33) What happens if an unsolicited proposal is submitted outside the submission window?

The solicitation states that unsolicited proposals submitted outside the announced window dates would be returned without review.

34) What is one of the biggest practical submission risks mentioned in the solicitation?

Two explicit return-without-review risks are highlighted: (1) submitting outside the annual window for unsolicited proposals, and (2) requesting a budget substantially above the typical annual award size without discussing it first with the Program Director.
