Seminar report review

Recovery of Rare Earth Elements Using Membrane Technology. Seminar_Report_Topic_Wise.docx (v1) vs Seminar_Report_Topic_Wise_v2.docx (v2), read line by line.

Submit v1. It reads like a scientific report. v2 reads like study notes.

Both files have identical formatting (Times New Roman 12, 1.5 line spacing, same margins, page-number footer), so this comes down entirely to structure, tone and content. v1 is a synthesis written in a formal register; v2 is closer to paper-by-paper notes with a conversational voice. v2 does carry more numbers, so the best final version is v1 with v2's extra data added in v1's tone.

ScorecardThe things an examiner checks first.

Check	v1	v2
Title page	Yes (name and roll number still placeholders)	Missing, opens straight on the contents
Abstract + keywords	Yes, three paragraphs and keywords	Missing
List of abbreviations	Yes, 34 terms	Missing, though it uses LSIP, HPTS, JM, CPI, LMH and many more
Voice	Formal, third person throughout	"We need…", "we should switch…", contractions
Spelling	Consistent UK (polarisation, characterisation)	Mixed: "polarization" and "polarisation" both appear
Topic-wise synthesis	Papers merged under each topic	Many sections open "This paper (…)" or "This team…", i.e. paper-wise
Analysis across papers	§4.3 draws trends: REE/REE factors only 3–12, single vs mixed salt drop, CP effect, stability	None. Numbers are listed, never interpreted together
Comparison chapter	Table 5.2 (8 criteria × 5 technologies) + §5.4 "Where membranes fit best"	Bullet points only
Conclusion	One synthesis of the whole report	Four paragraphs, each about a different paper; diafiltration and COFs not mentioned
Quantitative depth	Good	Higher (see "Take these from v2")

Why v2 sounds like notesLines from v2 an examiner would notice, with a formal version you could use instead.

v2 · §1.1, first line"We need more critical minerals, but extracting them sustainably is becoming difficult."

FormalDemand for critical minerals is rising, while their sustainable extraction is becoming increasingly difficult.

v2 · §3.4.3"This team tried something different. They left the filtering layer alone… More isn't always better."

FormalInstead of modifying the selective layer, the authors incorporated O-MoS₂ into the support. Beyond the optimum loading, performance declined.

v2 · §3.4.5"It is named after the two-faced Roman god Janus." / "acts like a lid that locks the MXene in place"

FormalA Janus membrane has oppositely charged faces. The cross-linked PA layer restricts interlayer swelling of the MXene.

v2 · §3.5.1, §3.4.2"a forest of tiny vertical COF nanorods", "it is hard for it to squeeze in"

Formalvertically aligned COF nanorods (~1 µm); the large hydrated La³⁺ ion faces a high entry barrier

v2 · §3.6.1, §3.2Note-style labels: "Big idea:", "Central question:", "Key lesson:"

FormalWrite these as normal sentences or subheadings.

v2 · §6.3"Scale-up: Need large area, low cost, reproducibility, long-term stability."

FormalScale-up requires large-area, low-cost and reproducible membranes with long-term stability.

v2 · Chapter 7, opening"To fix the problems holding back REE recovery from e-waste…" then "We need proper…", "we should switch…"

ProblemThe whole future-prospects chapter is scoped to one paper (e-waste), not the report's topic.

The tone also jumps between very casual and very heavy ("heavily solvated hydration mantle… sterically barred… unimpeded"). That mix reads as pasted from different sources, which examiners pick up on quickly.

Errors in v2Errors to fix wherever this text ends up.

§3.1 says "lithium product" in the brine pathway: Brine → evaporation → precipitation → impurity removal → lithium product. That's left over from the source paper. v1 already corrected it to "product".

§4.5 Gd³⁺ numbers contradict each other. The 7-day test says Gd³⁺ went "from 89% to 85%", but the same section gives the initial Gd³⁺ rejection as 94.25%. Check the Bao et al. paper and use one consistent starting value.

Take these from v2v2's real strength is depth. Rewrite these into v1 in v1's formal tone. Ticks save on this device.

LSIP-NF brine stages: Mg²⁺/Li⁺ 4.37 → 0.20 → 0.01 (98.9%, 97.1%, 71.4% Li⁺ recovery), and the 180 h stability run (7.0–8.8 LMH/bar, MgCl₂ rejection >94%)v2 §4.4 → into v1 §3.4.4
Battery wastewater result: 59.5% Li⁺ recovery, 88.0% direct Li₂CO₃ purity (>99.9% after recrystallisation), Rₐ = 11.1 nm anti-foulingv2 §8.5 → into v1 §8.5
Janus membrane details: pH 3 (~88% La³⁺), single-salt order Na⁺ < Mg²⁺ < Al³⁺, benchmark vs NF90/NF270/NF5, leachate figures Na⁺ ~37%, Ca²⁺ ~57%, Mg²⁺ ~59% (v2 doesn't say whether these are rejection or passage, so check the paper before using them)v2 §4.5, §8.2 → into v1 §3.4.5

Table 4.3: relative proton transport (LAP5n6-DPP 7.1%, LAP5n10-DPP 14.1%, gramicidin A 67.3%)v2 §4.8 → into v1 §3.6.2
Second ENP equation for the active layer with virtual concentrations, Jᵢ = −Pᵢ(dc̄ᵢ/dx + c̄ᵢ(zᵢF/RT)(dφ̄/dx))v2 §3.4.2 → into v1 §3.4.2
COF selectivities: Cs⁺/Sr²⁺ 14.0 → 13.3 and Sr²⁺/La³⁺ 5.4 → 2.1 (single → mixed); HBAB/TAPA diffusion coefficientsv2 §4.7, §3.5.1 → into v1 §3.5.1
Limitations of bioinspired membranes and of the channel study: channel density (proteins ~3 × 10¹²/cm² vs artificial up to ~40 × 10¹²/cm²), lipid-only testing, over-bindingv2 §6.2–6.3 → into v1 §6.1–6.2
NF90 vs LSIP-NF: NF90 left only 2.7 mg/L Li⁺ in permeate (0.6% recovery)v2 §5.4 → into v1 §5.4

Fix before submittingThese apply to v1 (and v2 has the same gaps).

Add in-text citations. The reference list is numbered [1]–[14] but the text never uses [n]. This is the biggest gap for a scientific report: every result and claim should carry its [n].
Complete the references. [2], [4], [5], [13], [14] have no authors, journal or year. [6], [10], [12] lack volume and page/article numbers. Use one style for all (e.g. Author, Year, Title, Journal, Vol, Pages).
Fill the title page: [Student Name], [Roll Number], [Department Name], [Institute Name], [Month, Year].
Check the contents page numbers. They are typed by hand, not generated by Word, so open it in Word and confirm each one matches (or replace with References → Table of Contents).
§1.3 Scope mentions "forward osmosis tests", but forward osmosis never appears in the body. Remove it or add the content.
Label Table 5.2 as a synthesis. Its ratings (Excellent / Good / Limited) are compiled, not quoted from a paper. Add "Compiled from [refs]" underneath so the source question doesn't come up in the viva.
Copper example in §1.1 (US Cu ore 1.8% → 0.40%) is about copper, not REEs. Fine to keep as an illustration of declining ore grades, but say so explicitly ("for example, in the case of copper…").

Bottom line

v1 has the parts a scientific report needs: title page, abstract, abbreviations, formal voice, cross-paper analysis, a comparison table and a real conclusion. v2 has more data but reads like notes, so a reader would assume it's paper summaries put together. Take v1, add v2's extra numbers in v1's voice, add in-text citations and complete the references, and it's ready to submit.
