#A new hydrogen-rich liquid, stable at #RoomTemperature, enables safer, more efficient #HydrogenStorage and transport, potentially advancing clean energy and industrial applications. @epfl_en @advmater doi.org/g9s874 techxplore.com/news/2025-07-…
BREAKTHROUGH: A safer way to trap greenhouse gases and store clean energy at room temperature.
“Scientists at BITS Pilani, have just developed a fluoride-free method to synthesize the metal organic framework MIL-101(Cr), eliminating the need for toxic hydrofluoric acid used in conventional processes.”
“By using acetic acid and nitric acid as modulators and a greener solvent, the team produced larger, more ordered MOF crystals with more open metal sites that enhance gas adsorption.”
“In experiments conducted at room temperature (~25 °C) and pressures up to 50 bar, the nitric acid modulated MIL-101(Cr) showed significantly improved CO₂ and water vapor capture, along with enhanced hydrogen adsorption.
“The improved performance comes from higher chromium content and optimized pore size, allowing gases to bind more efficiently under real-world conditions.”
Bro if this scales, we’re looking at affordable carbon scrubbers, practical hydrogen storage, and atmospheric water harvesting systems built from materials that are finally safe enough to make at scale.

Hydrogen has the highest energy density of any fuel by weight.
142 MJ/kg, nearly 3× gasoline (46 MJ/kg).
So why isn't it everywhere?
Because storing it is an engineering nightmare.
Liquid hydrogen must be kept at −253°C, just 20 degrees above absolute zero.
At that temperature, most metals become brittle and crack.
That's why cryogenic tanks are so heavy and expensive.
Alternative: store it as compressed gas at 700 bar. A 70 MPa pressure vessel strong enough to be safe weighs 20× more than the hydrogen inside it.
The new UC Berkeley alloy that doesn't crack at −253°C could directly address the liquid storage problem.

🧪 Room-temperature hydrogen storage.
A material that store remarkably high amounts of hydrogen is Lithium Boronhydride (LiBH₄).
For the material to be re-used after the synergistic dissociation of H₂ from B/LiH, a copious amounts of energy and elevate temp are required, making the desorption process costly and unpractical.
Here’s introduced a new reactant method to facilitate the dehydrogenation using synthesized Ni-decorated nano-clusters, which lowers the regeneration of LiBH₄ at temperatures down to 30 °C, removing altogether the thermodynamic hurdles associated with heating systems, gaseous compression and cooling cycles.

Hexanitrogen, energy density breakthrough.
A metastable Nitrogen allotrope consisting of six 𝑁 atoms dubbed hexanitrogen (𝑁₆) was recently lab-synthesized by reacting silver azide (𝐴𝑔𝑁₃) with chlorine 𝙲𝑙₂ or bromine 𝙱r₂ gas under reduced pressure at room temperature, followed by cryogenic trapping in argon matrices at 10 °K and in a liquid film at 77 °K.
The unique properties of this neutral nitrogenous specie formed by two open chains 𝐶₂ₕ -𝑁₆ are outstanding. The stability was computed at the dissociation barrier of 14.8 kcal mol⁻¹ x pair with an estimated half life above 132 years. The extreme high energy density and the only benign 𝑁 release upon decomposition, makes 𝑁₆ one of the best candidate for applications in clean energy storage discovered so far.

Part 1/3 – Inside a Humanoid 🤖🧲
Everyone talks about AI models in humanoid robots – almost nobody talks about the materials that make the hardware possible. Under the shell, today’s bipedal robots are basically walking rare‑earth magnet farms.
🧲A single Tesla‑class humanoid packs ~40 high‑torque NdFeB motors into its shoulders, elbows, hips, knees, ankles, torso and hands. Neodymium + Praseodymium (NdPr) deliver the torque density that lets a 70 kg robot move like a human instead of a forklift. Dysprosium and Terbium (Dy/Tb) are added to keep those magnets stable at the high temperatures you see in 24/7 industrial duty – without them, joints start to demagnetise and the robot literally loses strength.
🚦The head is just as rare‑earth heavy: Erbium and Ytterbium (Er/Yb) inside LiDAR and depth‑sensing lasers for 3D mapping; Yttrium, Europium and Terbium (Y/Eu/Tb) inside the phosphors that light up the robot’s displays and status LEDs. Even with clever tricks like inductive encoders (no magnets) in the motion stack, over 95% of humanoid motors still rely on rare‑earth permanent magnets today.
This isn’t just a robotics story – it’s a materials and supply‑chain story. The more joints we add and the more human‑like we make these machines, the more NdPr, Dy, Tb and SmCo we bolt into each unit. If forecasts of millions (or eventually billions) of humanoids are even half right, we’re looking at a rare‑earth demand shock that rivals – and then overtakes – EVs and wind. ♻️⚙️
Next in the series (Part 2): how humanoids could become the single most magnet‑intensive machines on earth – and what that means for NdFeB demand out to 2040.

🚨 CHINA RARE EARTH GROUP’S RADIAL & HALBACH (FLUX-CONCENTRATING) SINTERED NdFeB MAGNETIC RINGS NAMED "TOP 10 ROBOTICS INNOVATION" AT WRC BEIJING 🇨🇳🤖🧲
While headlines focus on AI software, the physical bottleneck of Humanoid Robots is torque density, thermal management, and miniaturization inside every joint actuator and dexterous hand.
At the 2026 World Robot Conference (WRC) in Beijing, state-owned giant China Rare Earth Group (China Rare Earth Group Innovation Technology Co., Ltd.) had its Radially Oriented & Flux-Concentrating (Poly-Magnetic / Halbach) Sintered NdFeB Magnetic Rings officially selected as one of the "Top Ten Innovation Achievements of Central Enterprise Robots" (中央企业机器人十大创新成果)!
🔬 WHY SINTERED NdFeB MAGNETIC RINGS ARE THE "MUSCLE" OF HUMANOID ROBOTS
Traditional segmented arc magnets require individual gluing onto motor rotors—introducing assembly tolerances, cogging torque, vibration, and eddy-current heat. Seamless one-piece sintered NdFeB rings solve this, and China Rare Earth Group showcased two distinct magnetic orientation architectures:
1️⃣ Radially Oriented Sintered NdFeB Ring (辐射取向磁环 , "Radiation Ring"):
• Target Application: Frameless Torque Motors inside humanoid rotary joint actuators (hips, knees, shoulders, elbows) and collaborative robots.
• Key Engineering Edge: Supports skewed/inclined magnetization with ultra-high assembly precision, drastically suppressing motor temperature rise, acoustic noise, and vibration while boosting motion control accuracy.
2️⃣ Flux-Concentrating / Multi-Pole Oriented Sintered NdFeB Ring (聚磁取向磁环 , "Poly-Magnetic Ring"):
• For Frameless Joint Torque Motors: Delivers ultra-high surface magnetic flux density and an optimized sinusoidal waveform, boosting motor output torque while reducing cogging torque (torque ripple).
• For Hollow-Cup (Coreless) Dexterous Hand Micro-Motors: Enables extreme miniaturization with high surface gauss and multi-pole magnetization, massively increasing power density and accelerating dynamic response speed for robotic fingers.
4 CORE METALLURGICAL & MANUFACTURING BREAKTHROUGHS:
Engineered specifically for cramped installation envelopes, high-frequency reciprocating motion, and continuous heavy-duty operation:
🔹 Magnetic Flux Consistency: Uniform field distribution across every pole.
🔹 Micron-Level Dimensional Accuracy: Preventing cracking during thin-wall anisotropic sintering.
🔹 Anti-Demagnetization Performance: High coercivity ($H_{cj}$) to resist thermal demagnetization under peak joint loads.
🔹 Structural & Mechanical Reliability: Built to survive millions of high-frequency start-stop cycles.

• Image 2: Miniaturized flux-concentrating magnetic rotor assemblies for coreless/hollow-cup dexterous hand motors.
• Images 3 & 4: The SASAC Central SOE Top 10 Robotics Innovations display in Hall C3 at WRC Beijing, where China Rare Earth Group’s sintered NdFeB rings sit directly alongside CSSC’s planetary roller screws and CASC’s embodied-AI linear joint actuators!

💡 THE STRATEGIC TAKEAWAY:
A single humanoid robot requires 28 to 40+ frameless torque actuators and 10 to 20+ hollow-cup hand motors, consuming 2 kg to 4 kg of high-grade sintered NdFeB magnets per robot. China Rare Earth Group isn't just mining and separating rare earth oxides; it is moving all the way downstream into finished, ultra-precision radially oriented and Halbach sintered magnet rings to dominate the global humanoid robotics supply chain.

JAPAN/KAWASAKI
HYDROGEN REVOLUTION begins now...
Japan could create a revolution with the first liquid hydrogen ship!
Japan is building the foundation for the future of clean energy.
Kawasaki Heavy Industries started construction on Japan’s largest hydrogen liquefaction plant in the Kawasaki coastal area.
This facility brings new records and massive capacity to the energy market
- Massive daily capacity: The plant can liquefy 50 tons of hydrogen per day.
- Breaking Japan's record: This new capacity is nearly 4 times larger than the previous record in the country, which was 15 tons per day.
- Advanced technology: The core system cools hydrogen to an extreme temperature of -253°C. This process shrinks the gas volume to 1/800th of its original size.
The goal of this project is to build the world’s first commercial international supply chain. Specially designed ships like the Suiso Frontier will transport clean energy across oceans from Australia and the Middle East straight into Japan.
The entire project is scheduled for completion at the end of 2028. Commercial demonstrations will officially begin in 2030 to prove the future of global hydrogen shipping.

New ‘hunter-killer’ chemistry captures and destroys forever chemicals
Researchers at Arizona State University and international collaborators have developed a catalytic membrane that destroys PFAS rather than merely capturing them. Palladium nanoparticles coating membrane fibers convert hydrogen gas into a reactive form that strips fluorine from the molecules. The work appears in the Proceedings of the National Academy of Sciences.
In a 58-day continuous test, the system removed more than 90% of six regulated PFAS compounds and stripped about 83% of the fluorine overall, confirming the chemicals were being broken apart. Hydrogen is fed from inside the membrane directly to the catalyst, bringing pollutant and reactive hydrogen together at the palladium surface. Rittmann describes it as a universal mechanism that worked across all six compounds tested.
The approach could complement existing treatment trains: conventional filtration would first concentrate PFAS into a smaller waste stream, which the membrane would then destroy instead of storing or disposing of it. Cost remains the main hurdle, since palladium runs around $50,000 per kilogram, making reduction of catalyst loading a top research priority. Hybrid designs pairing palladium with pollutant-degrading bacteria are also under development.

🛢️💰 Big Oil is about to double its profits.
The 5 Western majors will earn about $ 50bn in the 3rd quarter, against about $ 24bn a year ago.
ExxonMobil: about $ 17bn, +101%
Shell: about $ 10bn, +84%
Chevron: about $ 9.5bn, +158%
TotalEnergies: about $ 8.6bn, +111%
bp: about $ 5.8bn, +155%
The bigger driver this quarter is refining.
Shell has guided for a record refining margin of $42 a barrel.
Across the majors, refining margins are running 3-4 times last year’s levels.
That’s what happens when Russian refineries keep getting hit and Gulf exports are stuck behind Hormuz.
The world is short of diesel and whoever owns refineries gets paid.
The profits look locked in.
The test is what they do with the cash.
BP is paying down debt and HSBC doesn’t expect its buyback to return before 2028.
Shell buys back $ 3bn a quarter and HSBC sees $ 3.5bn in Q4.
Exxon and Chevron have also been cutting debt.
Investors want one thing above all: no spending spree on the back of a war windfall.
Results land on 29 October for Shell and TotalEnergies and on 30 October for BP, Chevron and ExxonMobil.
Buybacks, debt or new projects: what would you want them to do with the cash?

⛽️🚢5 fuels can move a ship.
Almost every owner still burns the same 2.
FYI: Marine fuel in Singapore went from $428 a tonne in January to $919 last week.
🔹Heavy fuel oil
The heavy leftover from refining, heated before it burns.
Still the workhorse.
🔹Marine diesel oil
Lighter and cleaner, and usually more expensive.
🔹LNG
It cuts CO2, but methane slip eats into the benefit.
🔹Biofuels
Some blends drop straight into today’s engines.
🔹Methanol
Fossil, bio-based or synthetic.
It needs engines built for it.
The surprise is that biofuel is sometimes cheaper than gasoil right now and buyers still pick gasoil.
Singapore’s marine biofuel sales fell 47% in 9 months.
Owners won’t commit until the IMO decides on its net-zero rules, due by early November.
So they order ships that can burn two fuels and wait.
Meanwhile, 1.8 million tonnes a month of heavy fuel oil has left the market.
That fuel bill is landing on someone.
My latest article names 8 listed companies on both sides of it.
