Abstract:
[Truncated abstract] The salient feature of next generation infrared (IR) on-chip integrated sensors is likely to be sensitivity in a narrow wavelength band that is tuneable over a selected range of the IR spectrum. It is proposed that this can be achieved by the integration of present-day HgCdTe IR detectors with thin-film based microelectro- mechanical systems (MEMS) optical mirror technology. Narrow-band sensitivity is obtained by optical resonance phenomena within a Fabry-Perot (FP) cavity, that is created by two Bragg reflectors and is monolithically integrated with an HgCdTe IR detector.

Abstract:
High performance polymer fibres are extensively used to make personal protective textiles and as reinforcing phase in polymer reinforced composite materials. This because of their excellent mechanical properties such as high tenacity and toughness, low elongation to break, and their ability to dissipate shock waves over a large area in a short amount of time. Over the past decades, braiding has become a very popular manufacturing technique and widely exploited in the composite industry for the production of advanced engineering parts. Braided reinforced structures offer certain advantages over

Ultra-sensitive photodetectors on-board space missions need very low temperatures to keep a good resolution. Cryo-coolers, such as pulse-tubes, help maintaining these conditions within a cryostat.

The first objective is to establish a test bench almost from scratch. The test bench includes a dummy representing the detector's support.

Abstract:
<p>Semiconductor wafer bonding has been a subject of interestfor many years and a wide variety of wafer bonding techniqueshave been reported in literature. In adhesive wafer bondingorganic and inorganic adhesives are used as intermediatebonding material. The main advantages of adhesive wafer bondingare the relatively low bonding temperatures, the lack of needfor an electric voltage or current, the compatibility withstandard CMOS wafers and the ability to join practically anykind of wafer materials. Adhesive wafer bonding requires nospecial wafer surface treatmentssuch as planarisation.Structur

Abstract:
Heterogeneous line broadening and spectral diffusion of the fluorescence emission spectra of perylene diimide molecules have been investigated by means of time dependent single molecule spectroscopy. The influence of temperature and environment has been studied and reveals strong correlation to spectral diffusion processes. We followed the freezing of the molecular mobility of quasi free molecules on the surface upon temperature lowering and by embedding into a poly(methyl methacrylate) (PMMA) polymer. Thereby changes of optical transition energies as a result of both intramolecular changes of

Abstract:
The usage of carbon fiber reinforced fiber polymer (CFRP) in the aerospace industry provides massive help. Because, they have extraordinary properties like high strength, more stiffness, and even lighter weight. Due to this reason the researchers want to find a deeper analysis of this material and provides crucial information to the aerospace and automobile industries. Among this, one field that we can look keenly in low-velocity impact behavior on CFRP. The main reason for this is because of the widespread nature of these materials. These are extremely sensitive to impact loads. Consequently
