No. 36 Steam Treatment Method in NH3-TPD

No. 36 Steam Treatment Method in NH3-TPD

A detailed explanation of the specific methods and precautions for steam treatment, which is considered effective for the removal of l-peaks!

Characterization of solid acid catalysts represented by zeolites is frequently conducted using the measurement of acidity through temperature-programmed desorption of ammonia. In this method, it is often observed that the spectrum exhibits two peaks, l (low temperature) and h (high temperature). The l-peak is attributed to ammonia that is further hydrogen-bonded to the NH4+ cation at the acid site and is not considered to indicate acidity. This document provides a detailed description of the specific methods and precautions for steam treatment, which is said to be effective in removing the l-peak. We encourage you to read it.

Handling and characterization of "all-solid-state battery materials"

Handling and characterization of "all-solid-state battery materials"

[Web Seminar] For those who are already involved in solid-state batteries, as well as for those who want to learn about them from now on!

All-solid-state batteries," for which research and development aimed at practical application is accelerating, involve processes such as ball milling, heat treatment, gas analysis, particle size distribution, particle shape, specific surface area, pore distribution, true density, and surface characteristics. They are attracting significant attention as secondary batteries with CO2 reduction, high safety, and large capacity and high output. Since all the battery constituent materials are solid, methods for sample preparation that enhance the compactness of the materials themselves and between the materials, as well as evaluation methods, are becoming increasingly important. This time, we will focus on grinding (ball milling) in material synthesis and measurement techniques for powder properties. [Seminar Content] ■ Retsch (Väder Scientific Co., Ltd.) - Grinding machine (ball mill) ■ Microtrac Bel Corp. - Specific surface area, pore distribution, true density, surface characteristics, particle size distribution, particle shape evaluation *For more details, please refer to the PDF document or feel free to contact us.

[Data] Evaluation of 3D Shape and Particle Size of Resin Pellets

[Data] Evaluation of 3D Shape and Particle Size of Resin Pellets

In the evaluation of individual particle diameters, it has become possible to assess the Z-axis "thickness" in addition to the XY axes, achieving effective classification and high data consistency!

The size evaluation of resin pellets is typically conducted using a caliper for three-dimensional (3D) assessment along the X, Y, and Z axes, or through sieve methods; however, both methods present challenges in terms of measurement effort. As a solution, two-dimensional (2D) evaluations using common image analysis methods and laser diffraction/scattering methods have been proposed, but the data does not align with caliper measurements or sieve methods, making them insufficient as alternatives. Here, we introduce the "Particle Shape Evaluation and Particle Size Distribution Measurement Device PartAn3D," which employs patented 3D imaging technology. This device achieves a high correlation with conventional methods by evaluating not only the XY axis (plane) but also the Z axis (thickness). [Contents] ■ Measurement Principle ■ Evaluation of Thickness Distribution through 3D Measurement (Sample: Resin Pellets) ■ Discussion ■ Evaluation Device *For more details, please refer to the PDF document or feel free to contact us.

[Data] Structural evaluation of carbon black using various measurement methods.

[Data] Structural evaluation of carbon black using various measurement methods.

It is possible to conduct a more detailed evaluation of the size of each constituent particle and the size of the gaps between the particles.

In this document, we will evaluate the physical properties of carbon black. Carbon black, primarily used as a filler in rubber and plastics, as well as in pigments and electrode materials, is known to have a structure consisting of the smallest unit aggregates made up of domains, and agglomerates formed by the aggregation of these aggregates. The physical properties of carbon black are mainly determined by particle size, particle surface characteristics, and structure. 【Features】 ■ Overview ■ Evaluation Equipment and Evaluation Items ■ Measurement Samples ■ Discussion ■ Summary ■ Measurement Results *For more details, please refer to the PDF document or feel free to contact us.

【Technical Information】What is adsorption?

【Technical Information】What is adsorption?

Adsorption technology has been researched for a long time and is also applied in industrial processes such as gas separation!

Today, adsorption technology is also applied in industrial processes such as gas separation. Adsorption has forms as shown in the diagram, and what is unclear is the difference between chemical adsorption and physical adsorption. Generally, when a gas molecule is adsorbed onto a material and has a strong bond (such as hydrogen bonds or acid-base interactions) that cannot be desorbed at the adsorption temperature or room temperature, it is called chemical adsorption. In contrast, physical adsorption is primarily due to van der Waals forces, and desorption is possible by vacuum evacuation. Currently, it is also recommended to stop using the terms physical adsorption and chemical adsorption and instead refer to them as reversible adsorption and irreversible adsorption. *For more details, please refer to the related links or feel free to contact us.*

What are the suitable theories and adsorbates for evaluating the pore structures of porous carbon and silica?

What are the suitable theories and adsorbates for evaluating the pore structures of porous carbon and silica?

[Web Seminar] Introduction to the Theory of Suitable Pore Distribution Evaluation and What Adsorbates Are.

In the Microtrac MRB Webinar Series 1 and 3, we introduced the points to consider in adsorption isotherm measurements, the BET specific surface area evaluation method, and classical pore structure evaluation (such as the t-method, capillary condensation theory, and adsorption potential theory). This time, using porous carbon, silica, and zeolites, which are used in various battery electrodes, gas separation, catalysts, and catalyst support materials, we will present an overview of the new pore distribution evaluation theory (NLDFT/GCMC) and from these evaluation cases, we will introduce what constitutes an appropriate pore distribution evaluation theory and adsorbate. Additionally, we will introduce the breakthrough curve measurement, which has been added as a new feature to the catalyst evaluation device "BELCAT II," along with measurement examples for single-component and two-component cases. *For more details, please refer to the PDF materials or feel free to contact us.

[Data] Evaluation of pore structure of porous materials using NLDFT method and GCMC method.

[Data] Evaluation of pore structure of porous materials using NLDFT method and GCMC method.

Evaluation of pore structure of porous materials with cylindrical pores using NLDFT and GCMC methods - Selection of suitable adsorbates and analysis methods?

So far, various methods for evaluating the pore structure of porous materials have been used based on the differences in pore structures. In the micro-pore region, methods such as the HK method, SF method, and CY method based on adsorption potential theory have been employed, while in the meso-macro pore region, classical pore distribution analysis methods such as the INNES method and BJH method based on capillary condensation theory have been used. On the other hand, in recent years, there has been growing attention on new pore distribution analysis methods such as NLDFT and GCMC, which allow for analysis based on a unified theory from micro-pores to meso-macro pores through computer simulations. This document examines which theory, NLDFT or GCMC, is more suitable for pore distribution analysis. Additionally, while the adsorbate proposed by IUPAC 2015 is Ar adsorption, it also investigates the usefulness of N2 adsorption. Specifically, it analyzes the N2 and Ar actual adsorption isotherms of mesoporous silica MCM41, MFI, and MTW zeolites. *For more details, please refer to the PDF document or feel free to contact us.*
