Martin et al. [102] reported a study in which LIBS was applied for the first time to wood-based materials where preservatives containing metals had to be determined. They applied PLS-1 block and PLS-2 block (because of the interdependence of the analytes) to multiplicative scattered-corrected data (a data pretreatment option of most use when diffuse radiation is employed to obtain spectra). They authors studied the loadings of a PCA decomposition to identify the main chemical features that grouped samples. Unfortunately, they did not extend the study to the PLS factors. However, they analysed the regression coefficients to determine the most important variables for some predictive models. 

A further development of static methods of hardness testing was a method devised by Brinell (1900), which consisted of driving a steel ball into the mineral to be tested for hardness under a pressure of 29.4 kN for about 30 seconds. Brinell hardness is defined as the ratio of load to surface of round indentation. The method has found wide use in engineering—for metals it is excellent, but in mineralogy it has proved unsatisfactory because of the high brittleness of most minerals and their non-deformability under the action of the steel ball. The ever wider application of Brinell s method and of a similar method developed by Janko in hardness determination of wood (Krzysik, 1974) should be noted. They are most useful in testing hard wood-base materials, such as compressed wood.

A general state-of-the-art plus bibliography was published by Harkin and Rowe in 1969 (11). Included was a section labeled "Wood-base Materials," which covered insulation board, hardboard, fiberboard, and particleboard containing bark. 

The present paper reports novel methods to prepare thermally meltable cellulose and wood-based materials and their properties. Two methods are emphasized (a) a grafting and (b) acylation combined with grafting. 

A summary of the results on volumetric capacity of storage of hydrogen for the investigated materials is given on Fig. 8. It is observed that the H2 uptakes are very low at room temperature and pressure 6 MPa for all carbon samples, but the wood-based material of large surface area has the best sorption characteristics - storage capacity equal of 80 ml(STP)/g.
