High-purity Hydrogen Generator Manufactured

Jo May 15, 2020

The research group led by Jang Tae Il at Nano Physics Engineering Institute succeeded in manufacturing a high-purity hydrogen generator, from which high-purity hydrogen can be obtained by electrolysis with a solid macromolecular polyelectrolyte film.

They have developed nano catalyst material with high electrolysis efficiency and stability, and electrolysis technology of electrolyzing solid macromolecular polyelectrolyte film, which ensured high efficiency of energy conversion and high purity of hydrogen – 99.99%.

At present they are making efforts to further raise the energy conversion efficiency, and to establish a distributed hydrogen energy system.

High efficiency waterproof agent developed

Jo Apr 23, 2020

The research team led by Choe Song Il, director of Mirae Industrial Technology Institute, Ri Nam Chol, laboratory head of the Institute, developed high efficiency carboxylic acid system permeation crystal type concrete waterproof agent from their own technology and this is proving highly effective in green building materials industry.

This grey powdered waterproof agent is mixed with a certain amount of water and applied to concrete plastered wall and it yields waterproofing effects in two days. What’s of particular characteristics is its peculiar watertight quality that coexists with the lifespan of concrete. This agent permeates into concrete as deep as 100mm and develops needle crystals so that it forms a stable waterproof zone.

Various portable analyzers developed

Jo Apr 22, 2020

Research team led by Kim Kum Chol, the laboratory head from the Faculty of Electronics, developed various high-efficiency portable analyzers with self-technology and is gaining public favors from various fields of national economy.

Colon bacilli analyzer developed by the research team analyzes colon bacilli in water, whose measurement range is 0~1 000/mL, minimum disjointing capability is 1/mL. Toxic gas analyzer analyzes CO, CO2, SO2, NO2, O3, H2S etc. in the air and its measurement range is 0~1 000ppm, minimum disjointing capability is 0.1ppm, analyzing time is less than 10s. The measurement range of procedure saltiness gauge used in the analysis of saltiness for underground ultra-salty water, soya and bean paste production process of basic foodstuff factories, saltiness of seawater, boiler feed water etc. is 0~30%, minimum disjointing capability is 0.1ppm. Of turbidity analyzer, measurement range is 0~10NTU and minimum disjointing capability is 0.1NTU. They are now developing their research work for further enhancing the accuracy of their analyzers.

The respected Comrade Kim Jong Un sent a birthday spread to Kim Jong Il Prize winner, Prof. and Dr. Ri Si Hup, a researcher of Faculty of Materials Science and Technology marking his 80th birthday.

Since he graduated from the university, Dr. Ri Si Hup worked as a researcher, vice-dean of science affairs, manager of scientific research and vice-president of science affairs for 51 years under the warm care of the Party. In those days he trained over ten science talents including doctors and wrote several books worth a treasure of the country such as “Encyclopedia of Metallic Materials” as well as 16 kinds of textbooks, reference books and essays of more than 40 000 pages, thus making a great contribution to the strengthening of the academic foundations for the major field.

Upholding the Party’s policy of giving priority to the science and technology, he waged a vigorous struggle to challenge others in terms of talent and search so as to complete research tasks arising in various sectors of the national economy and in the development of science and technology on the highest level. His achievements brought great pleasures to the great leaders and the respected Comrade Kim Jong Un several times.

Highly praising his achievement in the scientific research, the great leaders and the respected Comrade Kim Jong Un gave him thanks several times, awarded official commendations including the watch with the august name of the President, conferred the doctor’s degree and professor’s title, held him up to be the winner of Kim Jong Il Prize, the supreme honor of a citizen, and gave him honor to take part in a number of conferences including the National Conference of Intellectuals and had a photo session with him.

The respected Comrade Kim Jong Un learnt in person his birthday even in the busy days of revolutionary leadership and showed great benevolence of sending the birthday spread.

Receiving the spread full of love of the respected Comrade Kim Jong Un, he and his family, moved and excited, made up their minds to devote all their wisdom and passion to the breakthrough head-on to open up a new road for the building of a powerful socialist country.

Position Sensitive detector Developed

Jo Apr 2, 2020

The research group including Pak Pyong Su, a head of lab the of Semiconductor Institute, developed entirely in our own way the position sensitive detector available for all kinds of precision devices such as an electronic scale, a range finding system, a bevel gauge, a vibrometer, and other displacement sensing elements and are now expanding its achievements.

The element has a non-linearity error of 0.1% and position sensitivity of 0.2 to 0.3㎛.
