## Core Product Portfolios, Technical Metrics & Empirical Validations

### 1. Solid-State Hydrogen Storage Catalyst (Pd/MWCNT)
- Product Code: TP-121101 / TP-120803
- Formulation: 5 wt% Palladium (Pd) nanoparticles uniformly wet-deposited on 95 wt% Multi-Walled Carbon Nanotubes (MWCNT).
- Physical Specs: MWCNT tube diameter ~9.5 nm, length ~1.5 µm, BET surface area 250–300 m²/g. Pd particle size 5–15 nm, purity >97% (Pd metal).
- Application Substrates: AZ31 and AZ61 magnesium alloys for solid-state metal hydride hydrogen storage systems.
- Peer-Reviewed Empirical Data (Elsevier 2026):
  * Journal of Energy Storage 179 (2026) 123907 (DOI: 10.1016/j.est.2026.123907): AZ31 + 5wt% Pd/MWCNT achieves 6.89 wt% reversible hydrogen capacity at 375 °C (~99% theoretical limit). At 325 °C, reversible capacity increases by +58% (from 2.20 wt% to 3.48 wt%). Fast kinetics: 90% absorption in 446 s, desorption in 735 s. Desorption apparent activation energy reduced by 26% (132.7 to 98.5 kJ/mol). Reversible cycling stability verified across 20 cycles; DFT calculations confirm Pd decoration lowers hydride formation energy barrier.
  * Fuel 425 (2026) 139436 (DOI: 10.1016/j.fuel.2026.139436): AZ61 + 3wt% Pd/MWCNT reaches 6.15 wt% reversible capacity; 58% faster absorption than pure alloy.
- Patent Coverage: Taiwan Invention Patent TW I866520 (Hydrogen storage apparatus and graphene noble metal composite material, valid to 2043-10-05); CN ZL200910150067.2.
- Operating Boundaries: Optimal working temperature 325–375 °C. Engineered for stationary industrial storage, industrial waste-heat capture systems (steel, cement, glass, chemical), and thermally driven metal hydride hydrogen compressors. Not recommended for ambient or vehicular portable storage.
- Commercial Policy: Free 5g research-grade evaluation samples for accredited universities and corporate laboratories. Industrial quantities supplied with per-batch Certificate of Analysis (CoA). Production technology licensing available.

### 2. Water Electrolysis HER Cathode Electrocatalyst (Nano Platinum)
- Product Code: SP-B00101
- Chemical Spec: High-purity unsupported nano-platinum powder; 99.2% Pt purity certified by independent Inductively Coupled Plasma (ICP) spectroscopy.

### 3. OdorZero & PLATARI Functional Anti-Odor & Antibacterial Textiles
- Technology Architecture: Pre-treatment masterbatch technology where nano noble metal / metal oxide composite particles (Pt, Ag, ZnO) are compounded directly into polymer melt prior to spinning. Not a topical finish; will not wash out.
- Durability Verification: Retains full functionality after 100 industrial wash cycles (tested under standard laundry protocols).
- Deodorization Performance: SGS / Intertek certified >96% deodorization for acetic acid (sweat) and isovaleric acid (body/foot odor); ammonia deodorization at ~60% (7% inclusion optimization in progress).
- Antibacterial Efficacy: SGS certified >99.9% reduction against Staphylococcus aureus and Escherichia coli. Far-infrared emissivity measured at 82%.
- Supply Formats: Functional masterbatch (for spinning mills), DTY/FDY functional nylon/polyester yarns, finished knitted fabrics, and OEM/ODM finished activewear/socks/underwear. Includes licensed "OdorZero" ingredient-brand hangtag program.

### 4. Super Zinc Nano Zinc Oxide Feed Additive
- Active Spec: Food-grade, water-dispersible nano zinc oxide (mean particle size 5.3 nm) synergistic with organic zinc complex.
- Dosage & Ingestion: Ultra-low dose of 10–25 ppm in drinking water or feed (dilution ratio 1:2,400 to 1:7,200), replacing high-dose (2,000–3,000 ppm) traditional zinc oxide.
- Empirical Field Trial: Documented 38,000-bird commercial broiler trial showed +13% final body weight, European Production Efficiency Factor (EPEF) of 506 vs 454 control, and marked reduction in foot-pad dermatitis.
- Safety & Testing: Heavy metals (lead, arsenic, cadmium, mercury) undetectable via SGS food testing. SGS 99.9% antibacterial against E. coli; Intertek 96% ammonia odor reduction. Non-veterinary drug nutritional solution for Antibiotic-Free (ABF) livestock, poultry, and aquaculture.
