VASA Vanadium-Alloy Membrane for Ultra-High-Purity Hydrogen Purification
Non-palladium hydrogen-selective membrane module using a proprietary vanadium superalloy (VASA) to achieve >99.9999% H2 purity at lower material cost than conventional Pd-alloy membranes. The VASA module is designed for compact, low-maintenance purification systems targeting semiconductor fabs, hydrogen infrastructure, and medical applications.
Ultra-high-purity hydrogen (>99.9999%) is required for advanced semiconductor manufacturing (2 nm node, power devices), fuel-cell vehicles (H2 stations), and medical uses, but conventional Pd-alloy membrane purifiers are expensive due to palladium cost (~5,000/kg) and supply constraints. Vanadium is ~1/100th the cost with comparable theoretical H2 selectivity. However, vanadium membranes have historically suffered from hydrogen embrittlement and oxidation. UHP's VASA alloy formulation and module design claim to solve these durability issues.
PerovsJet inkjet coating system for perovskite solar cell R&D
A compact R&D inkjet coating platform purpose-built for perovskite layer deposition, using a glass/Teflon single-nozzle head that resists aggressive solvents (DMF, NMP) and requires under 0.5 mL of ink per evaluation cycle.
Perovskite R&D labs struggle to evaluate ink formulations at small scale because production slot-die coaters require large ink volumes and commercial inkjet printers lack solvent resistance for perovskite precursors. PerovsJet bridges the gap with 0.5 mL minimum ink volume and full chemical resistance.
Lithium-Selective Adsorbent for Direct Lithium Extraction (DLE)
A proprietary lithium-selective adsorbent material and associated concentration process that recovers high-purity lithium from salt-lake brine, geothermal water, seawater, and spent LIB black mass, requiring only pure water for elution.
Conventional lithium recovery from brine requires large solar evaporation ponds (months to years, weather-dependent, high water loss) or solvent extraction with chemical-intensive processes. This adsorbent enables selective lithium capture in a compact DLE process with no added chemicals for elution.
Turnkey liquid cooling infrastructure for AI data centers
End-to-end liquid cooling infrastructure for AI data centers including 1MW-class cooling systems, containerized mechanical rooms, chillers/dry coolers, secondary-side piping, and 1MW-class load bank pre-validation testing. Modular design for rapid deployment.

Enables compact, complex-shaped permanent magnets with tailored multi-pole magnetization patterns (radial, pole-anisotropic, convergent) for high-precision sensors and miniaturized motors, while offering rare-earth-free material options.
Electride-catalyst low-temperature low-pressure ammonia synthesis
Ammonia synthesis using electride-based catalysts that operate at lower temperature and pressure than conventional Haber-Bosch iron catalysts, enabling smaller modular plants.
Conventional Haber-Bosch economics favor very large centralized plants; lower T/P synthesis reduces vessel and compressor requirements so ammonia can be made onsite at hundreds to tens of thousands of tonnes per year where H2 and N2 (or power for their production) are available.
Onsite modular ammonia production system (electride catalyst package)
Skid/plant package that produces ammonia at the demand site using electride catalyst modules in the ~500–50,000 t/y class, reducing long-haul NH3 logistics.
Industrial and fertilizer users face shrinking domestic ammonia capacity and volatile import prices; onsite modules produce only the needed volume where hydrogen/nitrogen utilities exist, cutting dedicated transport and storage infrastructure.
Industrial ammonia dissociation unit for H2+N2 atmosphere gas
Electric catalytic ammonia cracker that produces mixed hydrogen-nitrogen atmosphere gas (nominal 3H2+N2) for heat treatment, sintering, and related industrial uses.
Users need a stable reducing/protective atmosphere without bulk hydrogen logistics; cracking liquid or vapor NH3 onsite yields a controllable H2-rich mixed gas with low residual ammonia and low dew point after drying.
TITERIX ammonia gas decomposition catalyst and ReNOX abatement unit
Proprietary catalytic system that oxidatively destroys high-concentration ammonia in exhaust gas with low NOx/N2O byproduct framing, packaged as compact ReNOX units.
Semiconductor, chemical, and industrial processes emit NH3-bearing exhaust or stripped ammonia gas that must be abated without generating large secondary NOx/N2O loads; compact catalytic destruction units address leak and stripping streams up to percent-level concentrations.
End-to-end CFRP/GFRP composite development from custom resin formulation to integrated assembly
60-year track record of full-spectrum CFRP product creation: in-house thermoset resin formulation, structural design and FEM analysis, mold fabrication, autoclave and filament-winding molding, 5-axis machining, coating, and system-level integration. Supports volume from single prototypes to 10,000+ units/month.
Overseas buyers of precision CFRP components — especially for semiconductor equipment, wind energy, and medical devices — typically must coordinate separately with a resin formulator, a design house, a molder, and a machinist. This fragmented supply chain multiplies qualification cost, lead time, and IP exposure risk.
Custom thermoset resin formulation for specialty composite applications
In-house development of custom epoxy, phenolic, and other thermoset resin systems tailored to specific application requirements — flame retardancy, heat resistance, chemical resistance, fast cure, or special surface appearance — integrated with CFRP/GFRP molding at production scale.
Standard prepreg systems from major suppliers (Toray, Hexcel) are optimized for aerospace structural properties but do not address application-specific constraints like flame/smoke/toxicity for public transit, chemical resistance for semiconductor wet processes, or fast-cure cycles for high-volume consumer-electronics production. Customers requiring specialty resin properties must either develop them in-house or work with multiple suppliers.
Silica White — Volcanic Glass Micro-Powder Concrete Admixture
A natural pozzolan micro-powder (volcanic glass ground to 3–4× cement fineness) that replaces a portion of Portland cement in concrete, reducing clinker factor while improving durability (waterproofing, chloride resistance, freeze-thaw resistance, ASR suppression). JIS A 6209 certified and JIS A 5308 listed. NETIS registered.
Reducing the clinker factor in concrete without sacrificing strength or durability is the primary lever for cutting construction embodied carbon, but supplementary cementitious materials (fly ash, slag, silica fume) face supply constraints and regional availability limits. Silica White offers a natural-pozzolan alternative sourced from domestic volcanic deposits.
CO₂-Nomicom — Carbonated Recycled Crushed Stone Aggregate
Recycled crushed stone aggregate from concrete demolition waste that fixes CO₂ through accelerated carbonation during processing. Used as road base, backfill, and subbase material. NETIS registered. Produced at multiple plants in Kanto region with combined capacity >2,000 t/day.
Construction demolition waste (concrete-ga ra) constitutes a major waste stream, and conventional recycling produces aggregate that still has a net carbon footprint from crushing and transport. CO₂-Nomicom converts the calcium-rich cement paste fraction into a CO₂ sink via accelerated carbonation, producing a carbon-negative recycled aggregate that can replace virgin crushed stone in civil engineering applications.
Amine-containing gel CO2 solid absorbent for low-cost capture from humid gas streams
A solid absorbent technology using amine-containing gel particles that captures CO2 efficiently from humid exhaust gas or ambient air without pre-drying, with weaker CO2 bonding enabling low-energy desorption.
Conventional amine solution scrubbing requires high energy for regeneration, equipment corrosion management, and pre-drying of gas streams. This solid absorbent operates efficiently under high relative humidity without pre-drying, and its weaker CO2 bond enables desorption at lower temperature, reducing total capture energy and cost.

Ultra-thin composite copper foil for lithium-ion battery anode current collectors
PET film (6µm) base with copper plating (~1µm per side) achieving 4µm total thickness, half the weight, and one-quarter the copper consumption of conventional rolled copper foil, enabling lighter, more resource-efficient battery cells.
Conventional rolled copper foil for Li-ion battery anodes is limited to ~8µm minimum thickness before handling becomes impractical (tearing, wrinkling). Thinner foil could reduce battery weight and material cost, but thin copper alone is too fragile. Teikoku Ion's composite approach uses a polymer film substrate for mechanical strength while plating ultra-thin copper layers for conductivity, breaking the thickness barrier.
PowerBinder natural-polymer water-based electrode binder for sustainable battery manufacturing
Alginate/gelatin/chitosan-based water-processable binders replacing NMP-solvent PVDF systems for lithium-ion battery cathodes, enabling safer, lower-cost, environmentally friendly electrode manufacturing.
Conventional Li-ion battery cathode manufacturing uses PVDF binder dissolved in NMP (N-methyl-2-pyrrolidone), a toxic, flammable organic solvent requiring expensive solvent recovery systems and posing worker safety and environmental risks. PowerBinder enables water-based cathode slurry processing, eliminating NMP entirely.
High-precision laser patterning system for roll-to-roll perovskite solar module manufacturing
Laser patterning system achieving 20µm minimum processing width with patented stretch-compensation and contour-following correction, designed for perovskite solar cell dead-zone minimization and roll-to-roll compatibility.
Perovskite solar module manufacturing requires P1/P2/P3 patterning of transparent electrode, charge transport, and perovskite layers with micron precision across large areas. Substrate thermal expansion and layer shrinkage during processing cause misalignment, reducing active area.
