Evaluation of MCM-41 Structure Using No. 11 t-plot Method (Application Edition 2)

Evaluation of MCM-41 Structure Using No. 11 t-plot Method (Application Edition 2)

[Data] Evaluation of MCM-41 Structure of Mesoporous Silica by t-plot Method (Application Edition 2)

This document introduces the structural evaluation of mesoporous silica MCM-41 using the t-plot method (Application Part 2) with graphs and tables. The N2 adsorption-desorption isotherm of mesoporous silica MCM-41 at 77.4K is classified as Type IVb, indicating the presence of mesopores. When examining the t-plot using silica as the reference t curve based on this isotherm, an upward shift due to capillary condensation is observed, confirming the presence of mesopores. *For more details, please refer to the PDF document or feel free to contact us.*

Evaluation of Pore Structure by No. 21 NLDFT Method and GCMC Method

Evaluation of Pore Structure by No. 21 NLDFT Method and GCMC Method

What are the optimal analysis methods and adsorbates for understanding the pore structure of porous materials? Various materials will be introduced as examples.

The NLDFT method assumes pore shape (pore diameter) and determines parameters at the adsorption temperature and pressure, using an approximate formula based on density functional theory for the adsorption density within the pores. The GCMC method calculates the adsorption density through computer simulations that model the adsorption phenomenon after determining the parameters. This document examines which theory, NLDFT or GCMC, is more suitable for pore distribution analysis, and how useful N2 adsorption is. We encourage you to read it. 【Contents (partial)】 ■ Figure 1 Local isotherms for 4nm and 10nm using NLDFT and GCMC (adsorption branch Ar@87.3 K) ■ Figure 2 Adsorption isotherms for MCM41 (N2@77.4 K, Ar@87.3 K) ■ Figure 3 Pore distribution (pore volume) for MCM41 (N2@77.4 K, Ar@87.3 K) ■ Figure 4 Adsorption isotherms for MFI1000H (N2@77.4 K, Ar@87.3 K) ■ Figure 5 Pore distribution (pore volume) for MFI1000H (N2@77.4 K, Ar@87.3 K) *For more details, please refer to the PDF document or feel free to contact us.

No. 22 Evaluation of Pore Structure of Activated Carbon Fiber by GCMC Method

No. 22 Evaluation of Pore Structure of Activated Carbon Fiber by GCMC Method

Modeling the pore structure from the pore distribution evaluation of activated carbon fibers using the GCMC method.

In this document, we evaluate the pore structure of activated carbon fibers (ACF) with slit-type pores using the GCMC method, and based on these results, we are examining pore shape models. Using the BELSORP MAX, we measured the N2 adsorption isotherm at 77.4 K for ACF (KURACTIVE FT-07) at ultra-low relative pressure (p/p0=1E-8) (pre-treatment: 300°C, 12 h). The measured adsorption isotherm is illustrated alongside the ideal adsorption isotherm calculated using the slit and carbon N2@77.4K GCMC kernel. We encourage you to read it. [Contents] ■ Figure 1: Adsorption isotherm of activated carbon fibers (ACF) (N2@77.4K) (pre-treatment: 573 K, 12 h, vac) ■ Figure 2: Comparison of the measured adsorption isotherm of ACF (N2@77.4K) and the ideal adsorption isotherm by GCMC method ■ Figure 3: Pore distribution (pore volume) and cumulative distribution (ΣVp) of ACF by GCMC method ■ Table 1: Comparison of ultra-super-micropore capacity of ACF by GCMC method ■ Figure 4: Slit pore model of ACF *For more details, please refer to the PDF document or feel free to contact us.

[Data] Shirutoku Report No. 19 # Evaluation of Electronic Device Structures

[Data] Shirutoku Report No. 19 # Evaluation of Electronic Device Structures

Contents to be confirmed in structural evaluation! Explanation of drop tests and waterproof tests.

★★Shirutoku Report: Useful Information You Should Know★★ This report introduces typical evaluations (drop tests, waterproof tests) conducted in the development and design of mobile communication devices. The drop test is the first test performed to confirm the strength of the casing. The waterproof test is based on protection ratings defined by IEC (International Electrotechnical Commission) and JIS (Japanese Industrial Standards), and it is necessary to select a testing method that suits the product's purpose. In terms of structural evaluation, there are other tests such as pressure tests and key press tests, and WTI is capable of handling various tests. If you have any inquiries about what can be done, please feel free to reach out to us.

Evaluation of Activated Carbon Fiber Structure Using No. 10 T-Plot Method (Application Edition 1)

Evaluation of Activated Carbon Fiber Structure Using No. 10 T-Plot Method (Application Edition 1)

[Information] Confirmation of adsorption on the external surface! Introduction to structural evaluation of activated carbon fibers using the t-plot method (Application Edition 1)

This document introduces the structural evaluation of activated carbon fibers using the t-plot method (Application Edition 1) with graphs and tables. The N2@77.4K adsorption-desorption isotherm of activated carbon fibers (kuractive: manufactured by Kuraray) is classified as Type Ia, indicating the presence of micropores. When evaluating this isotherm using the GCB as a reference t-curve in a t-plot, the slope of the t-plot changes sharply due to the filling of micropores, confirming adsorption on the external surface. *For more details, please refer to the PDF document or feel free to contact us.

Structural evaluation of activated carbon AX-21 by the αs method No. 14

Structural evaluation of activated carbon AX-21 by the αs method No. 14

[Information] It is possible to evaluate the surface area and pore volume of various materials and their pores!

This document introduces the structural evaluation of activated carbon AX-21 using the αs method, utilizing graphs and tables. The αs-plot method (SPE method: Subtracting Pore Effect) allows for the evaluation of surface area and pore volume of various materials. The analysis results obtained from the αs-plot (surface area and pore volume of each pore) are equivalent to those from the t-plot; however, since αs (-) is dimensionless, it does not have constraints such as lower limits compared to the t-plot, which considers the thickness of the adsorption layer (t) in nm, allowing for a more detailed understanding of information at lower relative pressures (micropore information). *For more details, please refer to the PDF document or feel free to contact us.

Structural evaluation of PCP/MOF and zeolites using gas adsorption methods.

Structural evaluation of PCP/MOF and zeolites using gas adsorption methods.

[Web Seminar] Lecture by Professor Masakazu Higuchi from Kyoto University iCeMS! Structural Evaluation of PCP/MOF and Zeolites by Gas Adsorption Method

With the advancement of various material developments, porous functional materials are increasingly attracting attention in the energy and environmental fields. In this webinar, we introduced the fundamentals of material evaluation using gas adsorption methods, which are essential for the characterization of porous coordination polymers (PCP/MOF) and zeolites, both of which are gaining attention as new porous materials. We also presented case studies on structural evaluation using new pore distribution analysis theories such as GCMC and DFT. Additionally, we invited Professor Masakazu Higuchi from Kyoto University's iCeMS, who is at the forefront of PCP/MOF research, to discuss the research trends and commercialization prospects of these materials. *For more details, please refer to the PDF document or feel free to contact us.*
