Reading & Writing Papers
Academic Papers in the LLM Era
@seokhyun choung|January 2026
This is my subjective opinion based on personal experience.
- I am a chemical engineer researching AI and computational chemistry-based catalysis
- I follow more chemical engineering researchers than materials engineering
- Leading groups are my personal impression - please take it as reference only
- Reading, writing, and sharing papers will remain valid for the next 5 years in the LLM era

How to Read Academic Papers
Only those who have read many papers can design good research, conduct it efficiently, and package results well to produce good papers
βUltimately, you read papers to write your own papers better
To convince your advisor (to become an independent researcher)
- Without reading papers and developing insight, you cannot conduct independent research
- To avoid being dependent, you need to know best
To avoid getting scooped
- What you think is "new" may not be new at all
- Read papers to quickly discover this and develop in different directions
To stay current
- Engineering research results have a half-life of about 5 years
- If you don't follow recent papers, you end up researching based on outdated results
Frequently read peer-reviewed papers from high IF, reliable journals
Historically prestigious journals like JACS or Angewandte are more likely to publish good papers

- Find leading groups in your field. You will notice recurring names
- Create a LinkedIn. See who is voicing important opinions
- Mind-map professors to follow (Research Rabbit is useful)
- Plenary/keynote speakers at conferences are leading groups (AIChE, NAM, MRS)
- Do paper studies regularly. Train your eye to recognize top groups

2-3 hrs
01Read critically: Don't accept claims blindly, find logical gaps
02Read actively: Make questions while reading, take notes
03Focus on figures: Figures are the core
04Check methods carefully: Verify reproducibility
05Follow references: Understand important prior work
06Set time limits: Don't spend too much on one paper
If you only see the world through the LLM lens, it can become a cognitive ceiling. Deep reading is still necessary.

2Writing Papers
How to Write Academic Papers
Researchers speak through papers
It is simply the format for voicing research to academia.
Assign value to your ideas
Research results not credited in time lose their value.
Quantitative metrics are needed
Professors secure funding through paper commitments.
Graduation and career
Students prove their achievements through papers.
"Writing papers is tedious" = "Getting recognition for my effort is tedious"
βNovel discovery or methodology
βClear key contribution
βReproducible methodology
βIn-depth discussion
βBeautiful figures
βLogical storyline
- This is the stage where you define the key contribution you want to deliver
- Generally target journals with IF 15 or higher
- Some values transcend IF. e.g., JACS is similar in importance to Nature Catalysis
- Usually the ceiling of research is determined from the start
Each journal has preferred topics (editor dependent)
Adv.Mat, EES family, ACS Energy LettPrefer electrochemical, SO. Rarely accept thermochemical
Nat.Catal, Appl Catal B, JACS, AngeAccept thermochemical catalysts
Best catalyst + Novel methodologyβNature Catal > JACS
AI-based computational methodologyβNature MI > ACS Catal
SO electrode material designβNature Catal > EES
Does not seem novelβConsult with peers and advisor
2-BPractical Writing
The Writing Process
When research matures, your advisor will signal to start preparing the paper
The most important thing is fast draft completion and fast iteration
Figure First!
Figure Prep
- Study how others compose figures
- Create expected scenarios before results
- Prepare about 5 figures
- Unclear figures are likely failures
Synopsis
- Build framework around figure set
- 3 bullet points per figure
- Move unnecessary to supplementary
Iterate A Lot!
"When someone points out something, there is usually a problem there. Even if you think 'this is perfect,' just fix it anyway."
- Haruki Murakami
If figures are well prepared, you can write in two days.
"Phenomena is complex and laws are simple... Know what to leave out." - Feynman
Speed is essential. Write quickly while your understanding is concentrated.
1MethodEasiest
2ResultsFollow figures one by one
3DiscussionHardest. Requires many references
4IntroductionFraming is difficult
5Abstract, ConclusionKeep it short
6TitleShorter is better
LLM one-shot quality is still subpar. It shows. (Around 93 points)
LLM Writing Issues
- Uses em dashes too much
- Vague and lacks substance
- Writes with exaggeration
Iterate until there is no trace of LLM.
Writing System Prompt
You are a scientific writing assistant.
1) No em dashes, ASCII only (H2O, CO2, x^2)
2) SI units with significant figures
3) Formal academic prose, passive voice
4) Include \citep{} and \citet{} format
5) No Unicode characters
Proofreading System Prompt
Check ONLY critical errors:
- Subject-verb disagreement
- Incorrect tense in methods/results
- Missing articles changing meaning
DO NOT FLAG: Style preferences, minor awkward phrasing
Output: [line] "error" > "fix" [reason]
LLM is useful for sentence-level grammar, but you must read multiple times for overall readability
A letter convincing the editor "why this paper should be published here"
Editors receive dozens of papers daily. Capture interest in 30 seconds
Para 1: Purpose
State paper title, authors, target journal
Para 2: Core & Novelty
What was done and why it matters. Include numbers
Para 3: Journal Fit
Why readers would be interested. Mention recent papers
Para 4: Closing
Reviewer suggestions (if required), thanks
Citation Principles
- Always cite the original source - avoid secondary citations
- Cite only the most important papers - reduce unnecessary citations
- Avoid excessive citations just to increase count
1. Trend statements
"Recent advances in MLIPs have enabled large-scale MD [3-5]."
2. Methodology
"DFT calculations were performed using VASP [7]."
3. Prior work comparison
"Similar relations have been reported [10]."
4. Differentiation
"Unlike conventional approaches [15], our method..."
Citations Not Needed
- Generally accepted scientific facts
- Sentences describing your own results
- Logical reasoning from this study
3Writing with LaTeX
LaTeX for Paper Writing
!Recommended only for full papers with 40+ citations, 10+ figures
!Paid: Overleaf, Free: Crixet recommended
!Not recommended when advisor needs close review
!Use Word for collaborative research
Word Pain Points
- Equation editing - click click, equations break
- EndNote update - plugin stops working
- Citation style change - 50% chance of breaking
- Move Figure - manually update all numbers
- Format change - 200 pages of adjustment
LaTeX Code Examples
\int e^{-x^2} dx = \sqrt{\pi}
\cite{Park2024}
\bibliographystyle{nature}
\ref{fig:name}
\ce{CO2 + H2O <=> H2CO3}
LaTeX separates content from formatting. You focus on science, the system handles format.

3LLM Era
LaTeX enables acceleration in writing and citations!
In 2026, LLM is accelerating paper writing (subjectively 2x+ faster)
- The number of papers is growing exponentially
- Peer review processes are being performed by LLMs [arxiv]
- AI-generated fatigue is accumulating, peer review journal importance may decrease
Future outlook: Presenting at major conferences or promoting research via YouTube may become more important. Materials and chemical engineering may follow AI community trends.
Nevertheless, the premise that "reading, writing, and promoting papers advances human knowledge" will remain valid for the next 5 years.
The quality and responsibility of all AI-generated content lies with the user
Not perfect yet
Best AI tools still produce outputs that show. Around 93 points.
Watch for hallucinations
You must verify important parts.
!Losing the power of thinking
!Losing your taste and preferences
!Falling into cognitive decline
LLM essay writers accumulated "cognitive debt" over 4 months

- Never input personal information (In AGI era, LLM could become a blackmail tool)
- Don't see the world only through LLM
- Deep reading is still necessary
