Detection Of Defects

Abstract This paper presented the recent application of die powerup in Thermal Imaging as applied to the detection of defects causing thermal failure on revenue products or units not being captured using other available techniques. Simulating the condition on an actual computer setup, the infrared (IR) camera should capture images simultaneously as the entire bootup process is being executed by the processor, thus revealing a series of images and thermal information on each and every step of the startup process. This metrology gives the failure analyst a better approach to acquire a set of information that substantiate in the conduct of rootcause analysis of thermal-related failure in revenue units, especially on customer returns. Defective units were intentionally engineered in order to collect the thermal response data and eventually come up with a plot of all known thermal-related defects.

Recent years have witnessed a fast development of solid phase synthetic pathways, a variety of solid-supported reagent and its applications in diverse synthetic strategies and pharmaceutical applicability’s. Polymer-supported triphenylphosphine is getting a lot of applications owing to the speed and simplicity in the process. Furthermore, ease of recyclability and reuse of polymer-supported triphenylphosphine added its advantages. This review covers a wide range of useful organic transformations which are accomplished using cross-linked polystyrene-supported triphenylphosphine with the aim of giving renewed interest in the field of organic and medicinal-combinatorial chemistry.

Phase Holograms

Maskless patterning techniques are increasingly implemented in semiconductor research and manufacturing eliminating the need for costly masks or masters. Recent application of these techniques to DNA and cell patterning demonstrates the adaptability of maskless processes. In this paper we present a new lithographic process for dynamically reconfiguring and arbitrarily positioning computer-generated patterns through the use of phase holograms. Similar to current maskless patterning methods this process can achieve pattern transfer through serially tracing an image onto a substrate. The novelty of our process, however, lies in the ability to rapidly fabricate complex micro/nanoscale structures through single-shot exposure of a substrate.

AbstractAging of the central face is typified by several common characteristics such as generalized volume loss, the appearance of a mental crease and marionette lines, thinning of the lips, and fixed and dynamic rhytids. These result from several processes such as atrophy of adipose and bone, changes in the support of the mandibular septum, and a loss of skin elasticity. There are many methods available for the improvement and rejuvenation of this facial anatomical area. Options include traditional surgical techniques, the application of volume and the use of laser, light, and energy-based devices. The recent application of biological interventions offers the possibility of cellular-based therapies to usher in a new era of true tissue regeneration. Optimal correction of the abnormalities may be accomplished through an understanding and identification of the causes of the observed abnormalities and targeting with the best available intervention. There are a growing number of techniques and technologies to accomplish this.

Langmuir Adsorption

The amount of acid sorbed by wool from solutions of sulphuric acid of four different strengths (namely, 0.0505, 0.0339, 0.0182, and 0.0101 molar) and containing sodium sulphate in amounts varying up to 0.16 molar has been determined. It has been found that the presence of the salt has little effect on the quantity of acid sorbed within those limits. The results are analyzed in the light of the theory of Gilbert and Rideal but this theory fails to give a satisfactory explanation of the results obtained. It is possible, however, to explain the results of the authors' experiments on the basis of the recent application of the Donnan equilibrium by Peters and Speakman. The Langmuir adsorption isotherm equation has been applied to data on the absorption of hydrochloric acid and of sulphuric acid by wool. The data appear to fit the Langmuir equation and give, for the maximum combining capacity, values that agree well with those estimated in other ways.
