Cellulose structure and lignin distribution in normal and compression wood of the Maidenhair tree(Ginkgo biloba L.)

Journal of Integrative Plant Biology 2015年第4期57卷 388-395页

We studied in detail the mean micro fibril angle and the width of cellulose crystals from the pith to the bark of a 15-year-old Maidenhair tree（Ginkgo biloba L.）. The orientation of cellulose micro fibrils with respect to the cell axis and the width and length of cellulose crystallites were determined using Xray diffraction. Raman microscopy was used to compare the lignin distribution in the cell wall of normal/opposite and compression wood, which was found near the pith. Ginkgo biloba showed a relatively large mean micro fibril angle,varying between 19° and 39° in the S2 layer, and the average width of cellulose crystallites was 3.1–3.2 nm. Mild compression wood without any intercellular spaces or helical cavities was observed near the pith. Slit-like bordered pit openings and a heavily lignified S2 L layer con firmed the presence of compression wood. Ginkgo biloba showed typical features present in the juvenile wood of conifers. The micro fibril angle remained large over the 14 annual rings. The entire stem disc,with a diameter of 18 cm, was considered to consist of juvenile wood. The properties of juvenile and compression wood as well as the cellulose orientation and crystalline width indicate that the wood formation of G. biloba is similar to that of modern conifers.

我们对从一个私人收藏家处借到的三枚所谓的"椰子珍珠"进行了研究分析。白色圆形的"椰子珍珠"表面具有奇特的平行沟槽结构,一侧有一个或三个小凸起。拉曼光谱学测试、密度测试和盐酸试验显示出样品本身是由多晶文石组成,显示平行的层状结构,与壳类材料一致。表面凹槽锉削痕迹清晰可见,表明这些"珍珠"是手工打磨成型的。根据制作这些样品的贝壳的厚度,以及在砗磲中观察到的类似结构,推测该样品是用巨大的蚌壳制作的,没有迹象表明这些"珍珠"是从椰子相关的原料中获得的。

Typology of Local Construction Materials from the Adamawa and North-West Regions of Cameroon

Geomaterials 2016年第2期6卷 50-59页

作者： Zo’o Zame Philémon Nzeukou Nzeugang Aubin Uphie Chinje Melo Mache Jacques Richard Ndifor Divine Azigui nni Jean Department of Earth Sciences University of Yaoundé Yaoundé Cameroon Local Materials Promotion Authority (MIPROMALO) Yaoundé Cameroon National Civil Engineering Laboratory (LABOGENIE) Yaoundé Cameroon

This article summarizes the different local construction materials observed in two regions of Cameroon (Adamawa and North-West). These raw materials were mapped and evaluated using various methods of investigation (spatial distribution, estimation of reserves, development of a database compatible with geo-referenced maps). The results obtained show three types of local construction materials (vegetal, pedological and geological) with quantitative estimation or distribution. Vegetal local materials include herbaceous savanna with strong dominance of straw in Adamawa region than the North West region. Pedological local construction materials include lateritic soils (ferruginous or clayey), harplan, sandy clay and sandy clay soil while geological local construction materials include volcanic, plutonic and metamorphic rocks. Many sites of these geological materials are suitable for the rock quarry plant. Adamawa region also contains sedimentary rocks constituted by metamorphic conglomerate and sandstones. Two main types of residential homes are constructed with these local construction materials in these regions of Cameroon. These include huts and houses.

Spectroscopic and calorimetric studies of congo red dye-amyloid peptide complexes

引用

Journal of Biophysical Chemistry 2010年第3期1卷 153-163页

作者： Kazushige Yokoyama Andrew D. Fisher Amanda R. amori Daniel R. Welchons Ruel E. McKnight 不详

Thermodynamic properties of complexes of Con ?go Red (CR) dye with amyloid ? (A?) peptides were studied by both absorption spectroscopy and isothermal titration calorimetry (ITC). Based on the absorption spectrum for the formation of CRAβ complexes in phosphate buffered saline solution (pH 7.4), van’t Hoff plots over a temperature range of 10oC to 70oC were created for CRAβ140, Aβ1228, and Aβ142. The plot for CR Aβ1228 complex showed a relatively linear feature within the given temperature range with ?H = –10.1 ?0.6 kJ/mol and ?S = + 0.128 ? 0.002 kJ/(mol K). However, the plot for CRAβ140 and CRAβ142 complexes exhibited two distinct linear regions with opposite slopes centered at a specific temperature, Ts, which was 54.7 ? 0.2℃ and 34.8 ? 0.2℃, respectively. The ITC experiments conducted at 25℃in water exhibited quite a different situation from the above mentioned spectroscopic approach. The ITC studies yielded a ?H of –85.3 ? 0.2 kJ/mol for the CRAβ1228 complex with negative entropy change –0.152 kJ/mol K). For CRAβ140, the ITC studies indicated the presence of two binding sites with ?H1 = –81.8 ? 0.3 kJ/mol and ?H2 = –119.5 ? 0.2 kJ/mol with K1 = 5.5 ? 0.7 ? 106 M1 and K2 = 6.9 ? 2.4 ? 108 M1, respectively. These binding constants are consistent with the model suggested by several studies. Both binding sites showed negative entropy changes suggesting that the formation of the complex is enthalpically driven. The disagreement in thermochemical values between two different methods confirmed that the enthalpy and entropy are heavily dependent on temperature and buffer/salt environment, and may involve inherently different reaction paths.
