A method of forming a cutting element may include subjecting a first press containing at least a diamond powder-containing container and a volume of a high melting temperature non-reactive material to a first high pressure high temperature sintering condition to form a sintered polycrystalline diamond wafer including a diamond matrix of diamond grains bonded together and a plurality of interstitial spaces between the bonded together diamond grains; and subjecting a second press containing the sintered polycrystalline diamond wafer and a substrate to a second high temperature high pressure condition, thereby attaching the wafer to the substrate to form a cutting element having a polycrystalline diamond layer on the substrate.. .

Use of nanodiamonds for generating free radicals for therapeutic purposes under radiation

The present invention relates to the use of nanodiamonds as drugs generating free radicals, in particular for treating tumours. The invention is based on generating free radicals on the surface of the nanodiamonds when they are exposed to radiation, for example ionising radiation.

Scattered pilot pattern and channel estimation mimo-ofdm systems

A method and apparatus are provided for reducing the number of pilot symbols within a mimo-ofdm communication system, and for improving channel estimation within such a system. For each transmitting antenna in an ofdm transmitter, pilot symbols are encoded so as to be unique to the transmitting antenna.

Co2 sensor based on a diamond field effect transistor

The present disclosure relates to a carbon dioxide sensor able to function in harsh environment, conditions. The carbon dioxide sensor can include a gate-less field effect transistor including a synthetic, quasi-intrinsic, hydrogen-passivated, single-crystal diamond layer exhibiting a 2-dimension hole gas effect, and a sensing layer comprising both a polymer and a hygroscopic material deposited onto a surface of the gate-less field effect transistor..

Diamond atr artefact correction

A method of using a spectrometer to produce corrected diamond attenuated total reflectance (atr) spectral data includes acquiring, using the spectrometer, an initial set of atr spectral data for a sample pressed into contact with a diamond atr crystals; numerically matching, using the spectrometer, a pressure dependent diamond artefact reference spectrum to a corresponding pressure dependent diamond artefact in the initial set of atr spectral data; and numerically subtracting out the numerically matched pressure dependent diamond artefact reference spectrum from the initial set of atr spectral data to yield a corrected set of atr spectral data for the sample for output by the spectrometer.. .
