The novel synthesis of formic acid has been achieved in a room temperature ionic liquid via the reaction of electro-activated carbon dioxide and protons on pre-anodised platinum. Only mild reaction conditions of room temperature and 1 atm CO(2) were used. This work highlights the effect of pre-anodisation on Pt surfaces.

This paper presents the effects of different annealing treatments and quenching conditions on characteristics titanium dioxide nanotubes (TNTs), which were synthesised successfully via two-step electrochemical anodisation. A novel approach was employed in this study by annealed TNTs using liquid nitrogen (N2). The XRD results showed that quenched N2 exhibited dissimilarities phase transition pl...

Nanocrystalline molybdenum oxide (α-MoO3) thin films with iso-oriented crystalline layers were synthesised by the anodisation of Mo foils. Upon band-gap excitation using light illumination, α-MoO3 generates excited electrons for reductive reactions and stores some of the excited electrons in its layered crystalline structure via alkali cation intercalation. These stored electrons can be subsequ...

A questionnaire was completed by fourteen world leading national metrology institutes to study the influence of several variables in the preparation of Ag/AgCl electrodes on the accuracy of Harned cell measurements of pH. The performance of each institute in the last decade has been assessed based on their results in eight key comparisons, organized by the Bureau International des Poids et Meas...

A process to fabricate porous silicon Bragg reflectors patterned on a micrometer lateral scale over wafer areas of several square centimeters is described. This process is based on a new type of projection system involving a megavolt accelerator and a quadrupole lens system to project a uniform distribution of MeV ions over a wafer surface, which is coated with a multilevel mask. In conjunction...

RH sensors have been made using porous polysilicon and porous SiC, both of which can also be made porous by electrochemical anodisation in HF, similarly to single crystal silicon. We show that polysilicon can be incorporated into a humidity sensor enabling a reduction (compared to single-crystal porous Si) of the effect of temperature on humidity measurements. We show that also porous SiC can a...
