Frequently Asked Questions (FAQs) - Nano Bio Phenomena and Processes in the Environment (NPPE) (NSF PD 15-1179)

What is the NPPE program?

The Nano Bio Phenomena and Processes in the Environment (NPPE) program (NSF PD 15-1179) is a National Science Foundation (NSF) funding opportunity that supports fundamental, quantitative science and engineering research on how nanostructured materials and nanosystems behave in biological and environmental settings.

What kinds of materials does NPPE focus on?

NPPE focuses on nanoscale materials and nanosystems, including 1D, 2D, and 3D nanostructures as well as heterogeneous nano-bio hybrid assemblies. A central premise is that materials can behave differently at the nanoscale than they do in bulk form, especially once they interact with complex biological or environmental media.

What environments and biological settings are relevant to NPPE?

The program emphasizes interactions between nanomaterials and real biological/environmental matrices such as living organisms, tissues, biofilms, soils, sediments, and other ecological media where mixtures of organic matter, minerals, microbes, and biomolecules can influence nanoparticle behavior.

What is the overall research goal of NPPE?

NPPE aims to advance rigorous, quantitative understanding of nano-bio-environment interactions, including how nanomaterials behave, transform, move, and impact biological systems. This includes both experimental and theory/simulation approaches and can also connect to practical environmental outcomes such as remediation strategies.

What are the main technical focus areas for NPPE proposals?

Proposals are expected to align with one or more of these key areas:

• Interfaces: Characterizing and explaining phenomena at boundary regions where nanoparticles or nanostructured surfaces contact complex biological or ecological media, including heterogeneous real-world composites.
• Predictive tools: Developing predictive tools grounded in fundamental behavior to support cost-effective and environmentally responsible processing and engineering solutions across the nanomaterial life cycle.
• Transport, interaction, and impacts: Studying how nanostructured materials move through water/soil/air, how they chemically transform, how they interact with cells/proteins/microbial communities, and what functional or toxicological effects may result.
• Complex simulations and theory: Advancing simulations and theory for molecular and interfacial systems, especially when paired with experimental validation, and developing new modeling approaches for transport and transformation in different media.

Does NPPE require experiments, or can it support modeling and simulation only?

NPPE welcomes both experimental and theory/simulation approaches. It specifically highlights complex simulations and theory development, particularly when simulations are paired with experimental validation, and it also supports creating new modeling approaches that predict transport and transformation.

Why does NPPE emphasize real-world, heterogeneous systems?

The program notes that natural and engineered environments often involve complex mixtures (organic matter, minerals, microbes, biomolecules). These components can strongly alter nanoparticle reactivity, aggregation, and fate, so studies of heterogeneous systems are emphasized rather than only idealized laboratory systems.

What kinds of outcomes does NSF expect from NPPE-funded work?

Expected outcomes include improved measurement approaches, better predictive simulation and modeling capabilities, stronger understanding of how environmental nanomaterials move and change across different settings and life-cycle stages, and foundational principles that support robust risk assessment and risk management for nanomaterials and nanosystems.

Is there an emphasis on safe design and management of nanomaterials?

Yes. A unifying theme is designing or managing nanostructured materials so their chemical, electronic, photonic, biological, and mechanical properties can be used effectively while also being handled safely.

Can proposals connect fundamental understanding to environmental applications like remediation?

Yes. The program description explicitly notes that NPPE welcomes work that connects fundamental understanding of nano-bio-environment interactions to practical environmental outcomes such as remediation strategies.

Does a proposal have to fit exactly into the listed focus areas?

No. The solicitation allows room for innovative ideas outside the listed categories. However, investigators are encouraged to contact the Program Director before submitting an off-scope or unusually framed proposal to reduce the risk of the proposal being returned without review.

What is the typical award size and project duration for NPPE?

NPPE typically supports unsolicited awards with durations of about one to three years and a typical budget on the order of about $100,000 per year.

What happens if a proposal requests substantially more than the typical NPPE budget?

Proposals requesting substantially more than about $100,000 per year are expected to involve prior consultation with the Program Director. Without prior consultation, such proposals may be returned without review.

What funding instrument and program classification does NPPE use?

The opportunity is offered as a grant (a discretionary funding instrument) under NSF Engineering Grants (CFDA 47.041).

Is cost sharing required?

No. The opportunity states that cost sharing is not required.

Who is eligible to apply?

Eligibility is listed as unrestricted, meaning a wide range of applicant organization types can apply, subject to any clarifications NSF includes in the full program guidance.

What does NSF expect in terms of novelty or transformative impact?

NSF emphasizes that proposals should clearly explain what is genuinely new or potentially transformative compared with prior work, why the work matters for engineering science, and what societal and/or industrial impacts could follow if the research succeeds.

Where should the novelty or transformative angle be presented in the proposal?

NSF expects the novelty or transformative angle to appear at minimum in the Project Summary, not only deeper in the narrative.

Are early-career faculty encouraged to apply, and is CAREER relevant?

Early-career faculty are encouraged to consider submitting a CAREER proposal when appropriate. The program notes that CAREER awards are typically five-year awards and references an annual Engineering CAREER deadline in July.

Are there other NSF mechanisms that may be relevant besides standard unsolicited proposals?

Yes. The program notes that EAGER and RAPID may be relevant in certain situations (both require prior discussion with the Program Director). It also mentions conference/workshop proposals and supplements, and similarly encourages investigators to discuss these options in advance.

How should sustainability-themed submissions be routed or labeled?

If a project significantly involves sustainable chemistry, NSF suggests submitting to the same program number (1179) but labeling the proposal title with a "SusChEM" prefix. The same concept applies for sustainable engineering.

What compliance requirements apply to NPPE submissions?

Compliance with the NSF Proposal and Award Policies and Procedures Guide (PAPPG) is mandatory. Noncompliant proposals can be returned without review.

Can proposals be returned without review, and why might that happen?

Yes. The description notes multiple reasons proposals may be returned without review, including (a) requesting a substantially higher budget without prior consultation, (b) submitting an off-scope or unusually framed proposal without discussing it with the Program Director, (c) PAPPG noncompliance, or (d) unsolicited proposals submitted outside the specified submission window.

What were the posted dates and status of the opportunity described here?

The archived opportunity details indicate it was posted July 24, 2015, had an original and current closing date of October 20, 2015, and an archive date of November 19, 2016. This suggests the record describes a past submission window, even though it reflects the research themes and proposal expectations for NPPE.

What was the estimated total funding amount listed in the archived opportunity?

The archived details list an estimated total funding amount of about $4.593 million.
