Area-Selective Depolymerization of Hydroxycinnamates Visualized by Raman Imaging in Miscanthus sinensis cv. Cell Wall

Journal of Agricultural and Food Chemistry, 2023
Lignin-carbohydrate complexes (LCCs) are regarded as a barrier for lignocellulosic biomass refinery. Here, confocal Raman microspectroscopy has been used to visualize the dissolution of hydroxycinnamates (HCMs) incorporated into LCCs by ether and ester bonds for energy crops Miscanthus sinensis cv. during successive NaOH (2.5% w/w) treatment.

Salvage brachytherapy of posterior pharyngeal wall squamous cell carcinoma in a previously irradiated area

International Journal of Radiation Oncology*Biology*Physics, 1997
Brachytherapy performed in patients with posterior pharyngeal wall carcinoma in a previously irradiated area is evaluated in terms of local control, survival, and complications.Between January 1982 and July 1993, 14 patients were treated with interstitial low dose rate brachytherapy alone for posterior pharyngeal wall squamous cell carcinoma in a ...

Area Expansivity Moduli of Regenerating Plant Protoplast Cell Walls Exposed to Shear Flows

Japanese Journal of Applied Physics, 2005
To control the elasticity of the plant cell wall, protoplasts isolated from cultured Catharanthus roseus cells were regenerated in shear flows of 115 s-1 (high shear) and 19.2 s-1 (low shear, as a control). The surface area expansivity modulus and the surface breaking strength of these regenerating protoplasts were measured by a micropipette ...

Cell wall porosity and available surface area of wheat straw and wheat grain fractions

Journal of the Science of Food and Agriculture, 1997
Interactions between polymers define many of the physical properties of plant cell walls. The most important of these are available surface area and the related measures of pore size and distribution. Gas adsorption and mercury porosimetry methods for the measurement of these parameters in wheat straw, whole wheat grain and grain fractions were ...

The role of cell walls and pectins in cation exchange and surface area of plant roots

Journal of Plant Physiology, 2017
We aimed to assess role of cell walls in formation of cation exchange capacity, surface charge, surface acidity, specific surface, water adsorption energy and surface charge density of plant roots, and to find the input of the cell wall pectins to the above properties.

INCREASE IN CELL WALL SURFACE AREA DURING ENLARGEMENT OF CAMBIAL DERIVATIVES IN ABIES CONCOLOR

American Journal of Botany, 1963
Wilson, Brayton F. (U. California, Berkeley). Increase in cell wall surface area during enlargement of cambial derivatives in Abies eoncolor. Amer. Jour. Bot. 50(1): 95–102. Illus. 1963.— Dimensions of fusiform cells (tracheids and sieve cells) and ray cells were measured from samples of the 1960 xylem and phloem increment of 5 trees felled at monthly ...

Electron-translucent angular areas in developing tapetum cell walls and pollen grains ofTilia platyphyllos

Protoplasma, 1999
InTilia platyphyllos, the anther tapetal cell walls undergo significant modifications from the tetrad stage onwards. During the tetrad stage the inner tangential and radial parts of the tapetal walls begin to dissolve, while the distal parts swell.

Effect of degradation on the porosity and surface area of forage cell walls of differing lignin content

Journal of the Science of Food and Agriculture, 1999
Cell walls, prepared from the stems of wheat, maize, lucerne and rape and from timothy grass, were degraded using a commercial cellulase enzyme preparation. Timothy and lucerne were extensively degraded (60–70% loss of dry matter) while dry matter losses from the more lignified maize, rape and wheat samples were substantially less (30–40%).

Volume, surface area and cellular composition of chewed particles of plant parts of eight forage species and estimated degradation of cell wall

The Journal of Agricultural Science, 1998
In order to understand more about the nature of forage particles before they enter the rumen and about the degradation of cell walls in the rumen, particles of different plant parts produced by sheep when eating each of eight plant species were described in terms of volume and exposed surface area and in terms of numbers of cells and volume and ...

High Surface Area Multi-Wall Carbon Nanotube Electrodes for H₂-Br₂ fuel Cells

ECS Meeting Abstracts, 2015
The regenerative H2-Br2 fuel cell has been a subject of great interest and is considered as one of the great candidates for large scale electrical energy storage [1, 2]. Since the bromine reactions in this fuel cell system do not need any precious metal catalysts, plain porous carbon paper can be used as an electrode material.
