Surface Chemistry. In the present case, we are looking at the surface chemistry of wood. There is a chemical surface and a physical surface.... Some properties of wood are controlled by surface chemistry and some by bulk chemistry. To a wood chemist, it is easy to describe the surface of a piece of 404 stainless steel. To a chemist working with stainless steel, it is easy to describe the surface of wood, but to a wood chemist, it is very hard to define the surface of wood.  2, record 1, English, - wood%20chemist

Oxophilicity is the tendency of certain chemical compounds to form oxides by hydrolysis or abstraction of oxygen, often from organic compounds. The term is usually used to describe metal centers, commonly the early transition metals such as titanium, niobium, and tungsten. Oxophilic metals are classified as "hard" within the HSAB [hard and soft acids and bases] concept. Many main group compounds are also oxophilic, such as derivatives of aluminium, silicon, and phosphorus(V). The handling of oxophilic compounds often requires air-free techniques.  2, record 4, English, - oxophile

An instrument combining a pulsed laser transmitter and optical receiver (usually a telescope) with an electronic signal processing unit used for the detection and ranging of various distant targets in the atmosphere, analogous to the principles of operation of microwave radar.  6, record 6, English, - lidar

Record number: 6, Textual support number: 1 CONT

The lidar technique operates on the same principle as radar; in fact, it is sometimes called laser radar. The principal difference between lidar and radar is the wavelength of the radiation used. Radar uses wavelengths in the radio band whereas lidar uses light, that is usually generated by lasers in modern lidar systems.  7, record 6, English, - lidar

Record number: 6, Textual support number: 2 CONT

There are three basic generic types of lidar : range finders, DIAL, and Doppler lidars. Rande finder lidars are the simplest lidars. They are used to measure the distance from the lidar instrument to a solid or hard target Differential Absorption Lidar(DIAL) is used to measure chemical concentrations(such as ozone, water vapor, pollutants) in the atmosphere. Doppler lidar is used to measure the velocity of a target High-resolution DEMs with vertical accuracy as good as 10 cm can be created with Lidar. Lidar is also better able to map bare earth elevations in forested or vegetated areas than other methods because only a single laser pulse needs to be able to reach between trees and the ground.  8, record 6, English, - lidar
