Enhancing Wear Resistance of UHMWPE Composites with Micro MoS and Nano Graphite: A Taguchi-DOE Approach.

This study presents an in-depth investigation into the wear characteristics of ultrahigh-molecular-weight polyethylene (UHMWPE) composites reinforced with microsized MoS and nanosized graphite particles. The objective is to enhance the wear resistance of the UHMWPE by examining the effects of various parameters and optimizing the wear performance. To achieve this goal, wet wear tests were conducted under controlled conditions, and the results were compared between composites with micro MoS and nano graphite reinforcements.

Microwave-assisted synthesis of GdOF: Eu/Tb ultrafine phosphor powders suitable for advanced forensic and security ink applications.

The rare-earth-doped inorganic ultrafine oxyfluoride host matrices in forensic science, especially in latent fingerprint detection and anti-counterfeiting applications, were still unexplored and may replace the existing technology owing to its high sensitivity. Herein, GdOF: Eu/Tb ultrafine red and green phosphors were synthesized via a rapid, green microwave-assisted hydrothermal method at 150 °C. The phosphors synthesized by this novel method possess good luminescent intensity for the hypersensitive D→F transition of Eu and D→F transition of Tb ions as compared to the phosphors prepared via other conventional methods such as co-precipitation synthesis, sol-gel synthesis, and microwave-assisted co-precipitation synthesis.

Optical limiting applications of resonating plasmonic Au nanoparticles in a dielectric glass medium.

Plasmonic nanostructures exhibiting high optical nonlinearities are widely used in the rapidly growing modern nanotechnology of nonlinear optics including biomedical applications due to their tunable plasmonic behavior. In this work, we investigate the nonlinear optical properties of uniformly distributed Au nanoparticles (NPs) embedded in pre-synthesized sodium-zinc borate glass by the well-known ion-exchange technique for optical limiting (OL) applications. Various techniques such as optical absorption spectroscopy, x-ray photoelectron spectroscopy, Transmission Electron Microscope (TEM), Photoluminescence, Time of Flight secondary mass spectroscopy and the Z scan technique were used for the characterization of these NPs.

Influence of gold nanoparticles on the nonlinear optical and photoluminescence properties of EuO doped alkali borate glasses.

Alkali borate glasses activated with trivalent europium ions and rooted with gold (Au) nanoparticles (NPs) were synthesised through a melt quenching process involving a selective thermochemical reduction and their applicability as photonic materials was assessed in detail. Non-linear optical (NLO) measurements were performed using a Z-scan approach in the wavelength range of 700-1000 nm. The open aperture Z-scan signatures for the Eu-containing glasses embedded with and without the Au NPs established a reverse saturable absorption (RSA) at all of the studied wavelengths ascribed to the two-photon absorption (2PA).

Association of Dermatoglyphic Peculiarities with Dental Caries in Preschool Children of Lucknow, India.

Background: Dermatoglyphics refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. The basis of considering dermatoglyphic patterns as genetic marker for dental caries is that the epithelium of finger buds as well as enamel has ectodermal origin, and both develop at the same time of intrauterine life.

Aim: To assess the relationship between fingerprint patterns and dental caries among preschool children of Lucknow city.

Prevalence and Association of Developmental Defects of Enamel with, Dental- Caries and Nutritional Status in Pre-School Children, Lucknow.

Background: Developmental Defects of Enamel in the primary dentition may be associated and predictors of dental caries and nutritional status. The aim of the present study was to assess the Prevalence of Developmental Defects of Enamel and its Association with, Dental-Caries and Nutritional Status in Pre-School Children of Lucknow, India.

Materials And Methods: Multistage Sampling was done.

Effectiveness of outreach program: a three year follow-up study among 12 years school students in lucknow.

Aim: To assess the effectiveness of outreach program in the 12 years school going children during a three year follow up period of Lucknow city.

Materials And Methods: A random sample of 298 school going children of age 12 years was drawn from adopted schools of Lucknow. Three years later the same population was re-examined with a population of 242 children of 15 y age group.

Treatment of recurrent attacks of supraventricular tachycardia during pregnancy causing complications in both mother and fetus.

Cardiac arrhythmias including supraventricular tachycardia are commonly encountered during pregnancy. The case of a young Indian woman with recurrent attacks of supraventricular tachycardia during pregnancy which was managed with adenosine and verapamil is reported. The possible mechanisms of maternal and fetal complications are discussed.
