# Lesson literature research

Search date: 2026-10-14. Mode: Deep Search.

## Contract

Update existing paper information and add studies supporting this lesson.
Keep every discovered paper as an individual Markdown record.
Keep the archive alongside root-level WORK_LOG.md.
The owner's revised rule uses root-level Theses.md as the register.
Keep each paper's complete entry in that register and its individual file.
Use primary metadata and readable primary papers for scientific claims.
Distinguish metadata, abstract evidence, full-text evidence, and unresolved leads.
Preserve frozen sources, accepted model statuses, and existing derivations.

## Need map

| Need | Lesson units | Decision affected | Required evidence | Status |
| --- | --- | --- | --- | --- |
| N1: Existing citation identity and scope | All units | Which papers already support the lesson | DOI/arXiv identity, canonical authors/year, local citation locations | Archived; malformed fragments explicitly unresolved |
| N2: Optical activation and finite PFC inventory | Chapter 2 | Whether laser/PFC activation assumptions transfer | Named formulations, pulse conditions, observations, phase-change limitations | Covered by reviewed optical abstracts and finite-droplet model evidence |
| N3: Directed jets, arrays, and impact | Chapters 1 and 3 | Which geometry and observables support transfer loads | Cavity/jet trajectories, boundaries, interaction experiments, impact observables | Covered for launch and observables; array primary methods remain unread |
| N4: Fracture, transfer, and gel confinement | Chapter 4 and Appendix A | Whether deformation, rupture, and transfer mechanisms are established | Interface competition, laser-transfer experiments, gel constitutive and failure measurements | Covered by fracture methods, transfer abstracts, and repeated-gel full text |

## Required record fields

Title; complete available authors; year; DOI or arXiv identifier/URL;
search date; two summary sentences; provenance; lesson mapping; evidence limits.
The summary's first sentence covers background and theory.
Its second sentence covers experiments or explicitly states unavailable evidence.

## Research limits

Published geometries require comparison with the project geometry.
Metadata verification does not establish experimental methods.
Unavailable methods remain explicitly unverified.

## Search and reading provenance

- Databases: Crossref, DataCite, Europe PMC, PubMed, and arXiv.
- Discovery: web search plus narrowly targeted Crossref queries.
- Primary reads: publisher abstracts, author manuscript abstracts, and selected full texts.
- Full-text reads include Feng (2007), Schoppink (author preprint), Bremer-Sai (2026), Verit (2022), and Sawada (2016).
- Some publisher and PMC pages returned access errors.
- Public metadata interfaces supplied indexed abstracts where available.
- Search snippets remain discovery leads.
- No PDF files were downloaded as deliverables.
- `search-ledger.json` preserves Crossref queries and every returned record.
- Web ledgers preserve every returned result URL and secondary DOI lead.
- `identifier-aliases.json` preserves merged versions and duplicate-source identities.
- The initial identifier inventory preserves local citation locations.

## Corrections found

- Boutopoulos's silver-ink paper has issue year 2014 and online year 2013.
- Three NIST material citations share one database DOI.
- “Optical characterization” in the shell study describes imaging of acoustic activation.
- Several author preprints duplicate published DOI records.
- Two local DOI strings are incomplete fragments.
- Sawada's DOI was resolved through its publisher PDF after metadata failure.
- Repeated cavitation can probe previously modified material.

## Synthesis

Brown's imaging separates jet mechanisms.
Abeid's multimodal measurements separate bubble motion from payload transport.
Together, they support distinct project measurements for launch and transport.
This project measurement design is an inference.

Feng measures competing fracture interfaces.
Li demonstrates sealed hydrogel-stamp release.
Together, they support matching the actual release interface before calibration.
The proposed matching step is an inference.

Bremer-Sai measures event-dependent material modification.
Gaudron models intact spherical viscoelastic media.
Together, they identify the need to track material state across reuse.
The required project damage law remains unestablished.

## Stop

The archive and five-unit evidence map satisfy the literature-management deliverable.
All discovered records are retained, including peripheral leads and incomplete fragments.
Further broad searches would add volume without resolving the project geometry.
Unreviewed experiments remain explicit gaps in metadata records.
Project-specific activation, outlet formation, impact, and repeatability remain unvalidated.
