Synthesis of Low-Thermal-Expansion Cordierite Ceramics Using Kaolin-Group Minerals
Authors:   Korean Industrial Technology Convergence Society, Kim Soonho
Published: July 2023

Cordierite (2MgO·2Al2O3·5SiO2) in the MgO·Al2O3·SiO2 system exhibits a low thermal expansion coefficient, high thermal shock resistance, low dielectric constant, and excellent electrical insulation properties. However, the material has a narrow sintering-temperature range. If the sintering temperature is too low, the crystal structure of cordierite does not form sufficiently; conversely, if it is slightly higher than ideal, the material decomposes into postelite, spinel, and mullite, leading to a significant increase in its thermal expansion coefficient. To overcome this problem, we adjusted the composition of cordierite by mixing it with predetermined amounts of kaolin minerals. After sintering at 1340℃, the resulting ceramic showed satisfactory physical properties, such as bulk density, absorption rate, and porosity. The optimal mixing conditions included a MgO/Al2O3 molar ratio of 1.006 and SiO2/Al2O3 molar ratio of 2.4277. Given its low thermal expansion coefficient(2.20 × 10−6/℃ at 800℃ and 2.57 × 10−6/℃ at 1000℃) and favorable physical and shrinkage properties, the cordierite prepared in this work may have potential applications in the development of kiln furniture materials for sintering next-generation secondary battery cathode materials.
Optimizing of Discharge Performance through Perforation in Lithium-ion Batteries
Authors:   Korean Industrial Technology Convergence Society, Park Chul-Soon
Published: July 2023

The discharge of lithium-ion batteries using perforation has gained attention as an environmentally -friendly alternative to the commonly employed salt water method. In this study, we optimize the discharge method using perforation by identifying the optimal perforation pattern and number. It involves forming perforations that penetrate the lithium-ion battery, resulting in complete discharge without generating wastewater containing hazardous substances. The study is conducted based on four different perforation patterns, and the optimal pattern and number are determined using temperature and residual voltage measurements. The results show that the voltage drop rate remains constant regardless of the type of perforation pattern, and the 1-row pattern exhibits superior results in terms of the heating temperature. This research contributes to the development of an eco-friendly and effective discharge method for lithium-ion batteries using perforation. Furthermore, the voltage drop experiment reveals that there is no significant improvement in the discharge time beyond the eight perforations. Consequently, the optimal number of perforations is determined to be eight.
A Study on the Perforation Line Model of PET Shrink Labels
Authors:   Korean Industrial Technology Convergence Society, Choi Young-Joe , Park Kyeong-Jin
Published: July 2023

The researchers found through comparative analysis of domestic PET shrink label perforation lines that the existing perforation lines differed in structure, hole shape, width, height, size, and spacing depending on the manufacturer and brand. As a result, it was inferred that the perforation lines of PET shrink labels may be related to the inconvenience that consumers feel when removing labels. Therefore, this study proposes a perforation line structure model that can solve the inconvenience of label removal that consumers experience during the separate collection of clear PET bottles. To this end, the researchers designed a diagonal perforation line model and conducted first and second cutting experiments. The results of the first experiment showed significant results with an average satisfaction rate of 87%. In the second experiment, it was confirmed through experimentation that the degree of cutting of PET shrink labels differs depending on the perforation line structure. As a result, it is noteworthy and significant that it was confirmed that diagonal perforation lines have utility as cutting lines due to their low heat resistance.

A field experiment was conducted in red lateritic soil during Kharif seasons of 1993 and 1994 to study the cumulative agronomic effectiveness of various organic sources with Mussoorie rock phosphate on phosphorus economy in green gram under rainfed condition. Use of Mussoorie rock phosphate (MRP) alone could not increase the grain yield significnatly. But its efficiency was increased by mixing with organic sources viz., farm yard manure (FYM), enriched bio-digested slurry (BDS) and phosphobacteria inoculation. Application of MRP with seed inoculation of phosphobacteria and enriched BDS alone gave the highest benefit whereas, single super phosphate (SSP) alone was uneconomical under rainfed conditions.

The efficiency of three herbicides viz., fluchloralin (0.90 kg ha''), thiobencarb (1.25 kg ha) and metolachlor (1.00 kg ha¹) on weed characteristics such as weed flora, relative density and relative dry weight of weeds, weed control efficiency, weed index and gran yield of three green gram cultivars viz., Co 4. NARP I and Co GG 89047 were evaluated in the field conditions. Among them, metolachlor followed by fluchloralin and thiobencarb reduced the relative density and relative dry weight of weeds over unweeded control. The sedge (Cyperus rotundus) was dominant followed by broad leaved weeds viz. Tranthenia portulacastrum and Amaranthus viridis). The broad leaved weeds contributed more dry weight because of their expanded leaf area and faster growth rate. The pre-emergence application of metolachlor followed by pre-sowing incorporation recorded maximum weed control efficiency and was on par with hand weeding. Higher weed index was observed in unweeded control irrespective of cultivars and the least was in metolachlor and this lead to higher grain yield in metolachlor treatment. Among the cultivars used, Co GG 89047 was found to be best and recorded higher grain yield.

Forty-two crosses of cowpea derived from 14 lines and 3 testers were utilised for heterosis and combing ability studies for green fodder as well as grain yield and yield components. Scope for exploitation of heterosis in cowpen was indicated with the materials studied. The highest heterotic expression for green fodder yield was recorded by the hybrid UPC 9201 x CO 5 (121.01 per cent) over the standard parent CO 5. The hybrid CS 55 x CO 4 recorded the maximum heterotic effect (215.34 per cent) over the standard parent for seed yield. The GCA:SCA variance ratio for all the traits showed predominance of SCA variance over GCA variance indicating predominance of non-additive gene action. Among the parents, the lines UPC 9103 and UPC 9201 and the tester CO S were found to be the best combiners. Selection of hybrids based on per se performance, seu effects and heterotic effects will be effective.

In order to transfer the desirable features of wild Arachis into cultivated groundnut, autopolyploids were induced in three diploid species viz.. A.cardenasii A.stenosperma and A.chucoense. The quadrivalent frequency in the autotetraploids was generally low ranging from 2.2 (A.cardenasii) to 4.7 per cent (A.chacoense). Despite moderate pollen fertility, the plants were used seed sterile. Hybridisation of the autotetraploids with different forms of A.hypogaea cultivars indicated that the crossability varied not only with the autotetraploids species but also with the different forms of cultivars used. The studies have resulted in the identification of plants having rust resistance transferred from wild species.
