Introducing the 2-Tiered Makeup of DualPore™ Particles

Particles that make up DualPore™ (hereafter referred to as DualPore™ particles) have microscale (10-6m) “through holes” in addition to conventionally found nanoscale (10-9m) “pores.”

“Through-holes,” or penetrating holes make way for substances to quickly access densely packed “pores,” allowing for the rapid adsorption, separation, and recovery of target substances inside DualPore™ particles. Together, “through-holes” and “pores” enable high liquid permeability and effective specific surface area, giving DualPore™ rise to various (structural) strengths.

 

Strength 1: High-Speed Processing and Adsorption

DualPore™ particles exhibit high performance even with larger particle sizes; For example, when used as an adsorbent, DualPore™ particles 3 times larger demonstrate performance equivalent with standard silica while still enabling processing speeds 81 times faster due to the lower back pressure.

Also demonstrating high performance under low pressures, DualPore™ particles are compatible with general DualPore™-purpose cartridge columns (tubes containing easy-to-replace packing materials) without the need for expensive high-pressure pumps and equipment. For this reason, it is easy to mass process at the ton (t) level. One can process 500+ tons of solution in just 1 week instead of the standard 1.5+ years using the same equipment with DualPore™.

Because of DualPore™’s excellent adsorption performance, one can treat residual concentrations less than ppm. Trace metals that otherwise cannot be concentrated by conventional methods due to excessive processing time, transportation costs, and/or capital investment become recoverable and recyclable. (We can also offer support in helping sell recovered material).

Strength 2: Energy-Efficient Continuous Flow Method

DualPore™ is ideal for continuous-flow chemical processing and synthesis.

In the manufacturing process and chemical synthesis, the repeated “batch method” in which raw materials are put into a container, allowed to react, stopped, and taken out, requires time, personnel costs, energy, capital investment, and generates large amounts of industrial waste.

The “flow method” is another method of chemical synthesis that has been around as long the batch method. While renowned for its compatibility with mechanically controlled processes, its limited processing capacity of the column has made the flow method unsuitable for the adsorption and recovery of trace concentrations of metals and mass production processes for complex compound synthesis. This is overcome using DualPore™, making for a durable, low pressure flow system where the reaction point is increased, further enhancing the flow method to become a much more environmentally friendly, time/energy/space efficient process than the batch method.

Starting with the synthesis of applications such as columns for metal recycling using adsorbents in the flow process, DualPore™ can immobilize the target catalyst in its pores so the catalyst does not mix with the product when multiple raw materials are input, allowing recovery of the material. This has been commercialized as the “heterogeneous catalyst type column (fixed catalyst).”

Please note that in 2015, Professor Osamu Kobayashi and his colleagues from the University of Tokyo discovered that flow synthesis reactions can be applied to complex chemical synthesis using the “continuous flow method,” and the possibilities for new applications are still expanding.

Strength 3: Numerous Uses of Silica’s Properties

The desiccant “silica gel” (SiO2) is an environmentally friendly material that can absorb various substances including moisture. Known as an element that exists in abundance next to oxygen in the natural world, silica gel has excellent chemical and physical stability, and is considered a safe substance. In order to enhance and utilize the characteristics of this silica gel, a variety of silica surface modification technologies have been developed.

“DualPore™ Silica”, the first practical example of DualPore™, can be developed for a wide range of applications by taking advantage of such properties.

Chromatography columns with DualPore™ Silica (normal phase) or surface modified with OctaDecylSilyl groups (reverse phase) (others are also available) are available for HPLC (stainless steel columns), Flash or OPEN.

In addition, DualPore™ Silica is highly resistant to organic solvents and exhibits high adsorption performance, even for highly viscous solvents at low back pressure, meaning that it can be applied to remove residual catalysts and impurities to improve safety and comply with pharmaceutical regulations at manufacturers or for high purification applications for semiconductor materials, functional polymers, and fine chemicals.

Alternatively, DualPore™ Silica can be used as a liquid chromatography column that can obtain a higher level of separation and purification even under low pressure. This characteristic becomes especially useful for peptide pharmaceuticals with large molecular weights and substances with large structures that have a low diffusion speed, where separation and purification by conventional chromatography technology is difficult.

Strength 4: Application Development with Other Materials

DualPore™ can also be applied to materials other than silica gel. For example, if applied to titania (titanium oxide), it becomes a highly efficient reaction catalyst that demonstrates the photocatalytic action of titanium oxide, in addition to the high strength derived from the material, as well as the corrosion resistance under strong alkali.
