17. Shintaro Matsuo, Satomi Tagawa, Yudai Matsusaki, Yuri Uchi, Tetsuo Kondo, Callose-synthesizing enzymes as membrane proteins of betula protoplasts secrete bundles of β-1,3-glucan hollow fibrils under ca2+-rich and acidic culture conditions, Holzforschung, 10.1515/hf-2019-0142, 74, 8, 725-732, 2020.01, Previously, it was reported that plant protoplasts isolated from Betula platyphylla (white birch) callus secreted bundles of hollow callose fibrils in acidic culture medium containing a high concentration of calcium ions (Ca2+). Here, the callose synthase was characterized from in situ and in vitro perspectives. Localization of callose synthases at the secreting site of callose fiber was indicated from in situ immunostaining observation of protoplasts. For in vitro analyses, membrane proteins were extracted from membrane fraction of protoplasts with a 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS) treatment. The CHAPS extract aggregated in the presence of a high concentration of Ca2+, suggesting that Ca2+ may promote the arrangement of callose synthases in the plasma membrane. The callose synthase activity was dependent on pH and Ca2+, similar to the callose synthase of Arabidopsis thaliana. However, the synthesized fibril products were longer than those produced by callose synthases of herbaceous plants. This is the first insight into the specific properties of callose synthases of woody plants that secrete of callose hollow fibers..

Shingo Yokota, Keita Kamada, Aki Sugiyama, Tetsuo Kondo, Pickering emulsion stabilization by using amphiphilic cellulose nanofibrils prepared by aqueous counter collision, Carbohydrate Polymers, 10.1016/j.carbpol.2019.115293, 226, 2019.12, Cellulose nanofibrils prepared by aqueous counter collision (ACC-nanocelluloses) have specific properties. In this study, the use of ACC-nanocelluloses as emulsifiers and stabilizers was investigated. Oil-in-water Pickering emulsions with long-term stabilities were easily prepared by ultrasonically mixing aqueous ACC-nanocellulose dispersions with non-polar solvents. Stable Pickering emulsions were obtained because the emulsification abilities of the ACC-nanocelluloses were significantly higher than those of cellulose nanofibrils prepared by high-pressure homogenization or other chemical preparation methods. This might be due to exposure of inherently hydrophobic surface planes of cellulose nanofibrils by ACC. The emulsification and stability of the Pickering emulsions were sensitive to the solvent properties such as permittivity, density and viscosity..

In this study, an ionic surfactant (sodium dodecyl sulfate, SDS) was used as emulsifier of oil-in-water and water-in-oil emulsions that were further costabilized by addition of CNF. The adsorption properties of SDS in both, CNF dispersions and emulsions, as well as the influence of composition (CNF and SDS concentration) and formulation (ionic strength, oil, and CNF types) on the phase behavior were elucidated and described in the framework of Windsor systems. At low salinity, the phase transition of emulsions containing CNF and SDS at low concentrations was controlled by molecular transfer in the oil-in-water system. Irregular droplets and "bi-continuous" morphologies were observed at medium and high salinity for systems containing high CNF and SDS concentrations. Water-in-oil emulsions were only possible at high salinity and SDS concentrations in the presence of small amounts of CNF. The results revealed some subtle differences in CNF interfacial activity, depending on the method used for their isolation via fiber deconstruction, either from microfluidization or aqueous counter collision. Overall, we propose that the control of emulsion morphology and stability by addition of CNF opens the possibility of developing environmentally friendly complex systems that display high stability and respond to ionic strength following the expectations of classical emulsion systems..

The addition of maleic anhydride and dicumyl peroxide improved the tensile properties and impact strength. With increasing ethylene-propylene rubber (EPR) and maleic anhydride (MAH)-modified ethylene-propylene rubber (MEPR), impact strength were increased, whereas tensile strength and Young's modulus were decreased. At the same EPR or MEPR content, the higher filler loadings resulted in higher Young's modulus and lower impact strength. Tensile properties and impact strength were greatly improved by adding EPR combined with maleic anhydride-grafted polypropylene (MAPP) and dihydroquinoline..

Wahyu Hidayat, Yue Qi, Jae Hyuk Jang, Fauzi Febrianto, Seung Hwan Lee, Hee Mun Chae, Tetsuo Kondo, Nam Hun Kim, Carbonization characteristics of juvenile woods from some tropical trees planted in Indonesia, Journal of the Faculty of Agriculture, Kyushu University, 62, 1, 145-152, 2017.02, The objective of this study was to evaluate the characteristics of charcoals from juvenile woods of albizia (Paraserianthes falcataria), gmelina (Gmelina arborea), rnindi (Melia azedarach), and mangium (Acacia mangium). Carbonization was performed at 400, 600, and 800°C for 10 min with a heating rate of 6°C/min. The physical, bioenergetic, and chemical properties were evaluated. Maximum char yield was obtained at 400°C and the increase of carbonization temperature resulted in a decrease of char yield. At the same carbonization temperature, char yield was higher in wood with greater initial density, i.e. ordered from the highest to the lowest: mangium, mindi, gmelina, and albizia. The heating values in all woods increased after carbonization, with maximum values at 600°C. Maximum energy densification ratio and energy yield were obtained at carbonization temperature of 600°C and 400°C, respectively. Char yield of 23.62-39.03%, heating value of 25.16-33.85 kJ/g, energy densification ratio of 1.45-1.72, energy yield of 39.09-60.10%, ash content of 0.80-3.94%, volatile matter of 14.61-38.69%, and fixed carbon of 58.58- 83.27% were obtained in all charcoals from juvenile woods and were comparable with those of mature woods, showing suitability for the production of charcoal fuel..

Maleic anhydride (MAH), dicumyl peroxide (DCP), and zinc oxide (ZnO) were added to the composites to enhance their tensile properties and dimensional stability. The dependence of MAH, DCP and ZnO concentration at various pressing time on tensile strength, elongation at break, Young's modulus, water absorption (WA) and thickness swelling (TS) of WF-CIR composites were examined. The tensile strength, elongation at break, and Young's modulus of the WF-CIR were greatly influenced by MAH content and pressing time. The higher the MAH cocentration and the longer time were applied, the greater improvement of tensile strength, Young's modulus, water absorption and thickness swelling parameters were obtained. However, the elongation at break was found to decrease with addition of MAH. DCP and ZnO concentration were also influenced the tensile strength, elongation at break and Young's modulus for WF-CIR composites..

The hydrophobic cores of the micelles were used to load a hydrophobic dye (4,7-bis[4-(1,2,2-triphenylvinyl)phenyl]benzo-2,1,3-thiadiazole, BTPETD) and exhibited a stable photoluminescence. The fluorescence emission can quantitatively and sensitively respond to 2,4-dinitrophenol (DNP) and picric acid (PA) due to the electron transfer between BTPETD and the explosives, and the limit of detection was 200 and 50 nM for DNP and PA, respectively. The novel hydrophobically modified cationic cellulose micelles have the potential to prepare feasible, sensitive and stable sensor systems for detecting explosives in aqueous solutions..

(UV-cut) films on the skin when the Antarctic ozone hole appeared. A collagen sheet was covered
with a polypropylene film containing zinc oxide and exposed outdoors in the Antarctic. Exposed sheets
were dissolved to determine total amino acid amounts. The results show that nearly 2.8 times as much
total amino acids were produced in collagen sheets exposed in spring, when the ozone hole appeared, as
those produced in collagen sheets exposed in autumn. However, total amino acids in a collagen sheet
covered by a film with a zinc oxide content of 0.40 v% decreased to nearly one-fourth the amount in
a collagen sheet covered with a zinc-free film, even during spring exposure. Furthermore, analysis shows
that total protein and terminal amino group concentration decreased substantially in extracts from
collagen sheets with increasing levels of zinc oxide in the film. In other words, the addition of zinc oxide
is confirmed to suppress collagen deterioration by UV light very effectively, even if exposure lasts 50 d in
spring, when the ozone hole appears. As described above, the collagen sheet method used for evaluation
could be used to quantify the protection effects of UV-cut film against high-energy UV light that reaches
the ground when the ozone hole appears..

(UV) light of short wavelength during a season of the Antarctic ozone hole. The collagen sheets were
exposed outdoors for 25 and 50 d, in the spring when the ozone hole was formed and in the ozone-holefree
autumn. Extracts from the exposed collagen sheets were analyzed for total protein and terminal
amino acid concentrations as an index of collagen fragmentation. The results show that the amount of
extractable collagen and terminal amino acid concentration in the spring exposure were approximately
double and five times higher, respectively, when compared with those in the autumn exposure. During the
ozone hole occurrence, the terminal amino acid concentration of the extracted collagen was about five
times higher when exposure lasted 50 d from mid-September to the end of October compared to when
exposure lasted 25 d from mid-September to early October. This result could be attributed to a limited
amount of short-wavelength UV radiation reaching the ground surface as a result of the low height of the
sun in September, when the ozone hole occurred. In fact, UV radiation measurements taken at Syowa
Station indicate that short-wavelength UV radiation in the range 290–295 nm was not detected until
approximately 1–2 months after the beginning of the ozone hole occurrence..

Paper containing waste green tea leaves did not have increased deodorizing ability compared with controls either against acidic odors such as hydrogen sulfide and acetic acid gases or against neutral odors such as formaldehyde and acetaldehyde gases. In contrast, the paper had excellent deodorizing ability against basic odors such as ammonia and trimethylamine gases. It was observed during additional tests conducted on paper samples containing 60 wt% waste leaves of oolong tea, black tea, pu-erh tea, or hojicha, that all the samples reduced the ammonia concentration to below 1 ppm, which is the threshold concentration for olfactory recognition, within 30 min. Further, paper containing waste green tea leaves was found to decrease the odor residual rate to 5.1% in 30 min even for a waste tea leaf content of 10 wt%. The excellent deodorizing ability of the paper could be attributed to the chemical reactions between odorous substances and the catechins found in tea leaves. After the deodorization of ammonia, paper containing waste green tea leaves was found to have increased antibacterial activity against Staphylococcus aureus. .

The nanocellulose thus prepared exhibited unique morphological properties. In particular, the width of the nanocellulose, which could be controlled as desired on nanoscales, was smaller than that of just secreted cellulose nanofiber, resulting in larger specific surface areas. Moreover, ACC treatment transformed cellulose Iα crystalline phase into cellulose Iβ phase with the crystallinity kept >70%. In this way, ACC method depending on the treatment condition could provide the desired fiber width at the nanoscale and the different ratios of the two crystalline allomorphs between cellulose Iα versus Iβ, which thus opens further pathways into versatile applications as biodegradable single nanofibers..

The NOC was prepared by stretching water-swollen gel-like films at the draw ratio of 2.0 to provide highly oriented β-1,4-glucan molecular chains of cellulose, which was proved by the high resolution TEM observation. In this paper, a detailed study of the unique ordered state of the NOC was attempted to characterize orientation of the main chains as well as the OH groups of molecules using polarized FTIR accompanied with a vapor-phase deuteration method. The dichroic analysis suggested that the main chains were fairly oriented in the stretching direction whereas the OH groups remained unoriented. The disordered state of the OH groups regardless of the oriented state for the main chain may hinder the oriented crystallization during the preparation of NOC films..

compounded papers containing wasted green tea leaves
needs to be examined before considering these papers for
long-term use. Hence, compounded papers containing
60 wt% wasted green tea leaves were irradiated for 1–200 h
using a xenon lamp to examine the effect of irradiation on
antibacterial properties of the paper. Irradiation for 20 h
(cumulative ultraviolet dose at 365 nm, 6.67 × 106 J/m2) or
longer was found to greatly increase the antibacterial activity
of the paper to a level at which no bacterial cell was
confi rmed to be viable. The paper was also covered with
various glass fi lters and irradiated for 1 h. Irradiation exclusively
with visible rays did not signifi cantly affect the antibacterial
activity of the paper, whereas irradiation exclusively
with ultraviolet rays, even for a short time, greatly increased
the antibacterial activity.
