Abstract: In laboratory conditions, the effect of minor oxides – MgO and SO₃ on formation of Portland cement clinker was observed. The research extended the current knowledge about the effect of these oxides on phase composition and structure of clinker and on alite polymorphism. Mainly means of optical and electron microscopy were used for the research.

Abstract: This article deals with the insight of using the positron (the simplest antimatter) as an entity that non-destructively probes material structure to the extent of atomic size defects, also describes the tools that have been in practice in recent times and in the front line activities. It also guides the reader on the use of (monoenergetic) slow positron beams that are currently available to study surface/ near surface structural details of various advanced materials. In addition, the bound state of electron and positron (positronium) is touched upon along with various conjectures for harnessing such species and utility of such light quasi-stationary states have been included. A brief mention has been made on the application of positrons towards medical diagnostic aspects and its recent importance in an astrophysical context.

Abstract: Currently, deep brain stimulation (DBS) is one of the most effective surgical treatments of treating serious stubborn resistance movement disorders (such as Parkinson's disease, essential tremor and dystonia, etc.). The nerve probe has been greatly favored by the authorities and scientists with the respect to the role it acted as the main brain stimulation tool. This article mainly introduces the materials of brain stimulated micro-electrode, the matched specifications and the evaluation on the compound functions in the developing course. The application prosperity and its development trendy will also be included with the intention to help people gain more systematic acknowledgement on the electrodes for deep brain stimulation.

Abstract: We observed the glucose concentration of solutions using a near-field microwave microprobe (NFMM). Instead of the usual invasive technique, we take the advantage of the noncontact and noninvasive evaluation capabilities of an NFMM. The NFMM with a high Q dielectric resonator allows observation of small variations of the permittivity due to changes in the glucose concentration. By measuring the reflection coefficient we could observe the concentration of glucose with a detectable resolution to 0.5 mg/ml (0.05 %). The glucose biosensor using a NFMM provides an unique approach for glucose monitoring for diabetes.
