📰 Chinese Super-Cooling Coating — Full Details
Source: South China Morning Post / Science and Technology Daily
Published: 18 Sep 2026
Developer: China Construction Eco-Development Co. (Suzhou) & Harbin Institute of Technology (HIT)
✅ Key Achievement
- A radiative cooling coating that lowers surface temperature by ~25°C on a clear 30°C day
- No electricity, no water, no refrigerants needed — purely passive cooling
- Mass production started — annual capacity: 600,000 tonnes
- Performance rated among the world's best
🧪 How It Works — The Technology
- Dual mechanism:
- High solar reflectance (97%) — bounces most sunlight away
- High infrared emissivity (97%) — radiates heat through the atmospheric "window" (8–13 μm) directly into deep space
- Composition: Inorganic fillers + polymer resins
- Innovation: Biomimetic design inspired by human skin wrinkles → achieves same performance at just 100 μm thick (down from 500 μm — thinner than A4 paper)
🏭 Real-World Trial — Hainan Petrochemical Plant
- Test period: 6 months (180 days)
- Subject: 3,000 m³ spherical liquefied gas storage tanks
- Results:
- ✅ Surface temp −25°C vs untreated tank
- ✅ Internal temp −7°C
- ✅ Replaced water sprinkler systems that consumed ~35 tonnes water/tank/day
- ✅ Withstood 40,000 scrub tests — no peeling/blistering
- ✅ Estimated lifespan: up to 15 years
- Quote: "Even during extreme heatwaves, the coating maintains safe interior temperatures." — Li Xiang, R&D Centre Head
📋 Development Timeline
Phase Detail
Lab origin Wang Fuqiang (HIT) — foundational academic research
Partnership Teamed with state-owned China Construction Eco-Development Co.
Optimisation Years of testing → manufacturing standards finalised
Field trial Hainan, 6 months real-world validation
Mass production Launched; 600,000 tonnes/year capacity
Future use Buildings, homes, public infrastructure
🌍 Potential Impact
- Building energy savings — less AC use
- Water conservation — replaces evaporative cooling systems
- Urban heat island mitigation
- Safety critical — keeps storage tanks stable in heatwaves
Clementi Fish Seller Fined S$2,000 for Harassing Pork Stall Owner by Telling Customer to Buy From Another Stall

Here's the full detailed account of the case:
Case Overview
Offender: Xu Zhenji (transliteration), 68, fish stall operator
Location: Block 448 Clementi Avenue 3 wet market
Date fined: 18 September 2026
Fine amount: S$2,000 — payable by instalments
Charges: 3 counts under the Protection from Harassment Act (POHA) → pleaded guilty to 1 charge, remaining 2 taken into consideration
Background & Origin of Dispute
- Both stalls had operated side-by-side for 6–7 years with no major issues — fish vs pork, not direct competitors
- Conflict began in 2024 over shared stall space usage
- After falling out, Xu repeatedly made loud remarks within earshot of customers that the pork stall sold frozen meat at fresh prices
Legal Timeline
Date Event
8 Aug 2024 Court grants Expedited Protection Order (EPO) — Xu ordered to stop insulting remarks
24 Feb 2025 Personal Protection Order (PPO) granted; Xu ordered to pay S$2,000 costs to pork stall owner
12 Jan 2025 Xu alleged to have made "frozen pork" remarks — breach of order
18 Nov 2025 Xu told a customer at the pork stall: "The pork next door is better — buy from them instead"
25 Feb 2026 Further "frozen pork" remarks — second alleged breach
18 Sep 2026 Sentencing: S$2,000 fine; payment by instalments allowed
Key Details
- Stall assistant confirmed CCTV installed at pork stall; described prior peaceful coexistence
- Xu's court stance: "I didn't fight with him or damage property — I only said the pork was frozen"
- When contacted post-sentencing: Xu declined comment, said she respects the court's decision
- Stall owner stated remarks harmed business and constituted harassment
