Micro-machining Techniques for the Fabrication of Fibre Fabry-Perot Sensors [PDF]
, 2006 Fabry-Perot optical fibre sensors have been used extensively for measuring a variety of parameters such as strain, temperature, pressure and vibration. Conventional extrinsic fibre Fabry-Perot sensors are associated with problems such as calibration of ...

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Processing of polycarbonate by high-repetition rate ArF excimer laser radiation
, 2022 S.557-561Precise ablation of polymers is a challenging task for excimer lasers emitting in the ultraviolet. Excellent edge definition and surface quality can be achieved, but efficiency and processing speed are limited due to losses induced by the masks.

Technology of compact excimer laser systems
, 2022 S.20-24Excimer lasers are pulsed gas lasers. Depending on the gas mixture laser emission is generated on single lines in the UV and VUV portion of the electromagnetic spectra. These emission lines are at wavelengths between 355 nm and 157 nm.

Geological Journal, EarlyView.Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

Reaction Rate Coefficients and Adduct Formation in the Cl Atom + (E)‐CF3CF2CH=CHCF2CF3 Reaction
International Journal of Chemical Kinetics, EarlyView.ABSTRACT In this work, rate coefficients for the Cl‐atom + (E)‐CF3CF2CH═CHCF2CF3 (HFO‐153‐10mczz, F22E) gas‐phase reaction were measured as a function of temperature and pressure, k(243–323 K, 50–300 Torr), using a pulsed laser photolysis‐resonance fluorescence (PLP‐RF) technique.

Heavy ion beam pumped KrF* excimer laser
, 2007 The high energy loss of heavy ions in matter as well as the small angular scattering makes heavy ion beams an excellent tool to produce almost cylindrical and homogeneously excited volumes in matter.
