“Char Yield Change with Time for Hydrothermal Carbonization of Glucose.”

In hydrothermal carbonization the yields of the solid and liquid products change with the conditions including temperature, time and heating rate. However, the relationship between condition and its effect differs from one researcher to another and has not been clarified. Therefore, we investigated the reaction characteristics of hydrothermal carbonization. We used glucose as the feedstock to investigate the behavior of char formation. We considered a reaction model from previous studies and calculated the carbon yield of some substances using high performance liquid chromatography. The results of hydrothermal carbonization of glucose solution in a batch reactor are reported.

“Fundamental study on supercritical water gasification of cellulose.”

The carbon gasification efficiency increases as the heating rate increases. In addition, solid biomass is gasified after its surface is dissolved. Therefore, it is necessary to allow time for dissolution. The common denominator between these two is the heating rate. If the heating rate is increased, sufficient dissolution time cannot be provided. Therefore, in this study, the effect of the heating rate on the carbon gasification rate was investigated by changing the length of the preheater at a reaction temperature of 600 degree C and a residence time of 40 seconds using cellulose.

“Potentially useful materials in seaweed: sugar-binding protein “lectin” and UV absorbing compounds “mycosporine-like amino acids”.”

Seaweed has been a familiar food and material in Japan, a country surrounded by the sea on all sides. Seaweed contains various unique components, among which our research group has focused on the sugar-binding protein “lectin” and the ultraviolet absorbing substance “mycosporine-like amino acids (MAAs)” as potentially useful materials from both basic and applied perspectives. In this seminar, I will introduce our recent findings on the effects of seaweed lectins on novel coronaviruses and new functionalities of MAAs.

Lecture: Ryoya OTA B4 student, School of Engineering, Hiroshima University
“Behavior of sulfate ion treated with formic acid under hydrothermal condition”
Behavior of sulfur during supercritical water gasification of biomass is crucial in terms of catalyst deactivation. It is expected that sulfate ion, once reduced, can be properly removed from the system. Thus, reduction of sulfate ion in the hydrothermal reactor is of interest. In this study, reaction of sulfate with formic acid was studied. Sulfuric acid was delivered to a hydrothermal reactor with formic acid, and liquid effluent was analyzed. The behavior of sulfur is discussed.

Lecture: Natsuki WATANABE B4 student, School of Engineering, Hiroshima University
“Reaction rate of uric acid under hydrothermal conditions”
Chicken manure is a typical waste biomass. It is used as energy by methane fermentation. However, there is a problem that nitrogen is converted to ammonia during the fermentation and this ammonia inhibits the fermentation itself. Since chicken manure contains large part of nitrogen as uric acid, its behavior during hydrothermal pretreatment should be important. In this study, uric acid was treated under hydrothermal condition in a batch reactor, and its decomposition rate was determined. Concentration of remaining uric acid was determined using absorbance after reaction with phosphotungstic acid.

Lecture: Takehiro KITAMURA M2 student, Graduate School of Advanced Science and Engineering, Hiroshima University
“Production of carboxylic acids by hydrothermal treatment of biomass”
Oil can be used as a biodiesel. Oil can be produced from acetic acid. Therefore, study about the production of carboxylic acid such as acetic acid, which can be produced from glucose, is important. In this study, hydrothermal treatment of glucose was performed to estimate the optimal hydrothermal reaction conditions for the acetic acid production. For this purpose, carbon yields and intermediates of acetic acid production were determined. The effect of the residence time and the oxygen equivalent ratio on the carboxylic acid yield has been investigated. Moreover, the effect of the heating rate on its production has been investigated.

Lecture: Yoshiko OKAMURA Professor, Graduate School of Integrated Sciences for Life, Hiroshima University
“An attempt to produce butanoic-acid in Escherichia coli”
Nitratireductor sp. OM-1 assimilates volatile fatty acids as carbon sources and accumulates high levels of butenoic acid, a raw material for chemical products, under nitrogen-depleted conditions, and converts it to butenoic acid polymer harboring ester bonds. OM-1 also accumulates polyhydroxybutyrate (PHB) and total lipid up to 90% of cell weight. On the other hand, despite its ability to produce and accumulate high levels of lipids, the production yield of OM-1 is not so high due to low-density culture. Therefore, we attempted to synthesize butenoic acid by heterologous expression of the butenoic acid synthesis pathway in E. coli, which can be cultured at high density.

【Lecture title】 “Turnkey Laser Ablation Method to Produce Graphene and Related Materials: Application to realize Smart Miniaturized Devices“

With the advent of cyber-physical system-based automation and intelligence, the development of smart wearable devices has dramatically enhanced. Evidently, this has led to the thrust to realize standalone and sufficiently-self-powered miniaturized devices for a variety of sensing and monitoring applications. To this end, a range of aspects needs to be carefully and synergistically optimized. These include choice of material, micro-reservoir to suitable place the analytes, integrable electrodes, detection mechanism, microprocessor/microcontroller architecture, signal-processing, software etc. In this context, MMNE Lab is working towards developing novel flexible devices having micro-reservoir, both in flow-through and stationary phase, integrated with graphanized zones created by simple benchtop laser. Various substrates, like different kinds of cloths, papers and polymers, have been harnessed to developed laser-ablated graphene regions alongwith micro-reservoir to aptly place various analytes to be sensed/monitored. Likewise, similar substrates have been utilized for energy harvesting by fuel-cell or solar routes, and supercapacitor-based energy storage. Overall, realization of a prototype is envisioned by integrating various sub-systems, including sensory, energy harvesting, energy storage and IoT sub-systems, on a single mini-platform. During the presentation, our work towards developing such prototypes will be showcased, and current and future commercialization potential will be projected.
