Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The pressure vessel steel A533-B used in the nuclear power reactors was heat treated to simulate thermal circumstances similar to those that could develop during a loss of coolant incident. The applied heat treatment resulted in phase transformation of the steel from tempered bainite structure into untempered lath martensite structure. The impact properties of the steel in the as-received condition and after heat treatment were evaluated. The results showed that the as- received steel has experienced serious degradation in the impact properties after exposure to heat treatment. The ductile to brittle transition temperature increased by 100oC and the upper-shelf energy was lowered by 30%. Room temperature impact test results showed 100% ductile fracture behavior of the steel with a total fracture energy of 200 J. After heat treatment, the steel displayed 100 % brittle fracture behavior with a total fracture energy of 12 J. Load-time curves of the instrumented impact tests showed that the decrease in the impact fracture energy was mainly due to the decrease in the fracture propagation energy than in the fracture initiation energy. Fracture surface morphology of specimens tested at room temperature revealed ductile microvoid coalescence fracture features for the as-received steel and brittle cleavage fracture features for the steel after exposure to heat treatment. The resulted embrittlement of the steel was discussed in relation to the phase transformation of the steel microstructure in consequence of the applied heat treatment.
Activated carbon adsorption has been widely used as an alternative environmental treatment to reduce metal ions, but it is less effective against heavy metals and other pollutants, including organic and inorganic compounds. Surface modification is required to increase the adsorption of activated carbon. To build up the information related to adsorption power of activated carbon modification, this study evaluated the theme relevant to adsorption of activated carbon modification using keywords "activated carbon" and "surface modification" as the data input. The database utilized for bibliometric analysis in this study was from Scopus with the help of VOSviewer software for network visualization of authorship, countries, citations, affiliations, and keywords. The analysis was carried out on February 3, 2022. The author limited the data by its year from 2013 to 2020 and the result was 262 documents. The results portrayed that the publication of activated carbon modification has been highly rocketing in the last eight years, specifically from 2019 to 2021. China is the leading country in activated carbon modification research, which results in the highest publications, most cited authors, and affiliations. Additionally, Elsevier is a publisher with the most top publications in producing activated carbon modification research articles. The keyword analysis showed that the studies related to activated carbon modification were mostly concentrated on characteristics of activated carbon, surface characteristics, adsorption, and environmental treatment. This bibliometric analysis study presented the relevant information on the surface modification of activated carbon to boost dangerous pollutant adsorption in the direction of environmental treatment.
