A product () for use on a surface or as part of a surface, the product comprising: a first layer () which carries an indication; and a second layer () which overlies at least a portion of the first layer (), the second layer () comprising a porous polymer; wherein the second layer () is opaque when dry such that the indication is masked and transparent when wet such that the indication is revealed.

Wet surface indication

A gas conversion apparatus () for converting a process gas to one or more other gases comprises: means () for introducing process gas into a liquid medium in a column (); and an ultrasonic energy generator () arranged to generate ultrasonic energy, the apparatus () being configured to launch ultrasonic energy generated by the generator () into the liquid medium such that process gas is exposed to ultrasonic energy, the apparatus () being arranged to allow collection of process gas that has been exposed to ultrasonic energy. The apparatus () also preferably comprises a microbubble generator () to generate microbubbles of the process gas for exposure to the ultrasonic energy. The ultrasonic energy generator () may be configured to generate ultrasonic energy as a consequence of a flow of a drive gas therethrough.

Apparatus and method for treating gas in a liquid medium with ultrasonic energy for chemical reaction

The invention provides a particle comprising a metal oxide which is doped with at least one rare earth element, wherein the metal oxide is selected from titanium dioxide, zinc oxide, cerium oxide and mixtures of two or more thereof. The invention also provides a pharmaceutical composition comprising the particles, and to uses of the particles and composition in the treatment and diagnosis of cancer.

A UV screening composition comprises particles which are capable of absorbing UV light so that electrons and positively charged holes are formed within the particles. The particles are adapted to minimize migration to the surface of the particles of the electrons and/or the positively charged holes when the particles are exposed to UV light in an aqueous environment.

Ultraviolet light screening compositions

A UV screening composition comprising particles which are capable of absorbing UV light so that electrons and positively charged holes are formed within the particles, characterised in that the particles are adapted to minimise migration to the surface of the particles of the electrons and/or the positively charged holes when said particles are exposed to UV light in an aqueous environment.

Rare-earth-activated phosphors

Microelectrode biosensor and method therefor

Phosphor compositions are prepared by treating metal oxides or mixed-metal oxides with refractory metals to form cathodoluminescent phosphors stimulatable by electrons of very low energy. The phosphors comprise 90% to 100% of a mixed metal oxide M ,T O (where M is a metal selected from Zn, Sn, In, Cu, and combinations thereof; T is a refractory metal selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and combinations thereof; and O is Oxygen, x, y, and z being chosen such that z is at most stoichiometric for M T O ) and 0% to 10% of a dopant comprising a substance selected from a rare earth element of the lanthanide series, Mn, Cr, and combinations thereof, or stoichiometrically excess Zn, Cu, Sn, or In. A blue-light-emitting phosphor based on ZnO treated with Ta O or Ta to form Ta Zn O is characterized by CIE 1931 chromaticity values x and y, where x is between about 0.14 and 0.20 and y is between about 0.05 and 0.15. In preferred embodiments, a process is specially adapted for forming the phosphor in an electrically-conductive thin-film or surface-layer form in situ during fabrication of displays. A preferred in situ process has an integrated etch stop, which precisely defines the depth of an opening in a field-emission display structure utilizing the low-energy-electron excited phosphor. A field-emission display comprises cells, each having a field-emission cathode and an anode comprising at least one cathodoluminescent phosphor. Arrangements of various color phosphors may be made by selective deposition of suitable dopants. The display cell structures may also have gate elements for controlling electron current flowing to the anode and its phosphor when suitable voltages are applied.

Self activated rare earth oxide nanoparticles

A device for the in vivo measurement of the concentration of an analyte in an aqueous solution comprises a transmitter for illuminating a body part with light at a plurality of predetermined wavelengths. A detector receives light from such body part and generates input signals representative of the intensity of received light at each of the predetermined wavelengths, and a computer coupled to the detector generates an output signal representative of the analyte concentration in the body part by analysis of the input signals received from the detector. The detector is adapted to generate input signals representative of the intensity of light received at three discrete wavelengths, and a formula is provided for calculating the output signal on the basis thereof.

Optical glucose detector

The light emitter is fabricated from a silicon substrate (,) that has a layer of porous silicon (,) on its upper surface. A hole transporter (,) is applied to the upper surface of the porous silicon (,) and penetrates the channels (,&prime;) formed within the porous silicon. An upper semitransparent p-type material such as NiO is used as the upper contact (,) to the hole transporter and a further contact is formed on the base of the silicon wafer (,). The penetration of the hole transporter into the interstices between the silicon particles significantly improves the efficiency of the light emitter by up to two orders of magnitude. The light emitter is particularly suited to use in VLSI and display applications.
