However, to achieve better performance some of them are still mounted as discrete components on the top of the module. An example of this type of component is a capacitor. In principle, no technological or design obstacles exist that would prevent the integration of capacitors into the module. The only problem is a lack of suitable LTCC material that exhibits the proper dielectric characteristics and is compatible with current LTCC materials and technology. Because the NP0-type capacitors represent the largest group of capacitors used with LTCC modules for RF applications we started the development of an NP0-type ceramic layer suitable for direct implementation with existing LTCC production lines. In this talk an example of such development will be presented where the very fundamental research has successfully been upgraded with an applied research and the new functional LTCC layers have been developed. They are characterized by K80, temperature stability, low dielectric loss and cosinterability with commercial low K tapes and silver electrode. The review of all the material properties relevant for the existing LTCC technology shows the possibility of a direct integration of the developed NP0-capacitor layer into the current LTCC modules.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87565706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SPV array performance depends on different parameters such as incident insolation, temperature, array layout, shading etc. Shading due to cloud cover results in Non-Uniform Illumination (NUI STATES- BRIGHT, GREY and DARK). Mismatch in currents and voltages of the modules due to change in one or more parameters leads to loss in output power. Hence real time monitoring of current (I, di/dt) for each solar module and bypass diode in the SPV array is necessary. In addition temperature sensors are required to monitor open-circuit voltage (Voc) fluctuations. Previously, we have demonstrated optimization of an SPV array in BRIGHT and DARK state [1]. However in field testing we have observed an intermediate GREY state as well. The power output can be depressed in a string having multiple state modules in series. In this paper we have proposed a reconfiguration strategy whereby modules are categorized into BRIGHT, GREY, and DARK illumination states. Based on this strategy it has been demonstrated that a reconfigured SPV array will yield maximum power at the highest operating voltage.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85429433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optical detection techniques are perhaps the most common due to their prevalent use in biology and life sciences. Fluorescence-based detection in Bio-MEMS has been applied to detection of cells within micro-chips, using antibody-based assays. Majority of the detection schemes in microarray and numerous lab-on-a-chip devices and applications utilize optical detection schemes. For size shrinkage, and to reduce the hardware we proposed the new read-out method which utilize the electrical detection method. The paper present design and analysis of microcantilever based biosensor based with electrical read-out method. This method is ideal for the manufacture of low cost disease diagnostic Kits. The sensor structure is designed and simulated using Coventorware software. The corresponding deflection with respect to voltage and stress is analyzed.

The XRD studies revealed that there is a phase transition from β- to α-phase on doping with rare earth ions. The FTIR results showed that there is a dramatic stress on the Si-O bonds due to the effect produced by means of A-site vacancies resulted, on substitution of Eu3+ and Sm3+ in Ca2+ site. The particle size was estimated by TEM (Transmission Electron Microscopy), it was compared with the size determined by Scherrer's formula. The SEM (Scanning Electron Microscopy) of β-CaSiO<inf>3</inf> shows that it is a porous material containing agglomerated nanoparticles.

Water and wastewater treatment is a matter of global concern. With more stringent control measures being imposed to protect the source of fresh water it is imperative for the industries to bring down the concentration of hazardous pollutants in their effluents to the permissible level by adequate treatment. Water reuse and recycle has therefore acquired a great importance as the availability of fresh water will control our economic growth more than anything else, since it is basic need of life and has no substitute. The present day wastewater treatment plant for industries as well as domestic water purifiers are mostly using primary and secondary treatment processes. However, in order to comply with the stringent environmental norms more efficient treatment will be required and addition of tertiary treatment step like heterogeneous photocatalysis which ensure the complete mineralization of pollutants has thus become necessary.TiO2 is the most used photocatalyst because of its high efficiency, nontoxicity, chemical and biological stability, and low cost. Herein we report the photocatalytic applications of prepared rutile Titanium Dioxide Nanoparticles, prepared by reverse microemulsion process using a non-ionic surfactant Triton X-100 as a template at room temperature. The as synthesized TiO2 samples were characterized by XRD, FTIR, BET, SEM and TEM. X-ray diffraction study shows pure rutile TiO2 Nanopatricles. TEM image shows spherical TiO2 Nanoparicles having average size 57 nm. As prepared rutile TiO2 sample were used for the photocatalytic degradations of Methylene Blue Dye, Rhodamine B Dye and p-Nitrophenol. % COD reduction shows 83% degradation for Methylene Blue, 84% for Rhodamine B and 76% for p-Nitrophenol within 150 min only. The photocatalytic reaction shows first order kinetics.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81574524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
