Coating Of Zinc Substrates With Fluorosilane Molecules Using A Water-Treatment Technique As A Pre-Coating Procedure For The Creation Of Superhydrophobic Surfaces, Renz Ronald R. Prieto, Marvin U. Herrera

Journal of Metals, Materials and Minerals

Superhydrophobic surfaces were successfully created when zinc substrates were coated with molecules with low surface energy through grafting of fluorosilane molecules. The zinc substrate underwent water-treatment technique as a pre-coating procedure to enhance the reaction sites for the grafting of fluorosilane molecules. The water contact angle of the samples went as high as 161.1° ± 0.8°. At lower fluorosilane-ethanol soaking times, water contact angles have lower values while at higher soaking time, it has higher water contact angle values. At 240 min fluorosilane-ethanol soaking time, optimum value of water contact angle was achieved. Fluorosilane molecules are widely distributed through the …

Effect Of Compaction Pressure On The Structure And Mechanical Properties Of Functionally Graded Aluminium-Glass Microsphere (Fgagm) Foams Produced By Powder Metallurgy Process, Vicheka Moeun, Seksak Asavavisithchai

Journal of Metals, Materials and Minerals

Functionally graded aluminium-glass microsphere (FGAGM) foams were successfully fabricated via powder metallurgy. The influence of compaction pressure on the structural and mechanical properties of the foams was systematically investigated. The study observed that increasing compaction pressure enhanced the green (pre-sintering) density of FGAGM foam, while post-sintering densities exhibited a decreasing trend with higher compaction pressures. The mechanical examination indicated that mechanical properties improved significantly with higher compaction pressures. While higher compaction pressures generally improve mechanical properties, the study identified that excessive pressures could lead to the fracture of GM particles, introducing defects that compromise the foam's structural integrity. Therefore, determining …

Effect Of Lanthanum Doping On Phase Transition, Piezoelectric And Energy Storage Properties Of Lead-Free 0.93(Bi0.5na0.5)Tio3‒0.07batio3 Ceramics, Pathit Premwichit, Songphop Jaila, Sasiporn Prasertpalichat

Journal of Metals, Materials and Minerals

In this study, lead-free (Bi0.465Na0.465Ba0.07)(1–x)LaxTiO3 (x=0.0‒0.04) ceramics were synthesized using a conventional solid-state reaction method. All samples showed a single-phase perovskite structure with pseudocubic symmetry. The dense microstructure revealed a decrease in average grain size as x increased. La3+ addition stabilized polar nanoregions (PNRs), shifting the ferroelectric to relaxor phase transition temperature (TF₋R=104℃ for x=0.0) to below room temperatures as La3+ content increased. This resulted in a transition from a rectangular to a relaxor-like thin P–E loop (x≥0.01), indicating a shift from ferro-electric (FE) to relaxor ferroelectric (RFE), which …

Structural, morphological, and optical characterizations, including X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, and ultraviolet–visible diffuse reflectance spectroscopy, provided supporting evidence for the successful formation of Bi2O3/AgI heterojunctions with likely close interfacial contact. The optimized Bi2O3/AgI composite with a 50:50 mass ratio …

Aluminium Oxide Particles-Containing Organogels For Cleaning Of Optical Glass Surfaces, Galina Vladimirovna Lyamina, Oksana Valerievna Dubinina, Alfa Edison I Lela

Journal of Metals, Materials and Minerals

Hypothesis:  Some types of cleaning methods are not very effective and can actually increase damage to the optical parts being cleaned. As an alternative to these methods, we propose the use of gel-like substances to remove contaminants from optical surfaces. We have developed a method for cleaning optical glass surfaces that uses organogels, which are based on copolymers of methyl methacrylate and methacrylic acid. These organogels are loaded with polyethylene glycol, and aluminum oxide particles (Al2O3), which help to effectively remove contaminants without causing damage to the surface.   Experiments:  Al2O3 nanoparticles prepared by a Nano Spray Dryer were added to …

2020-Current year OA Pubs

BACKGROUND: Previous studies have shown that colorectal cancer incidence is increasing among younger adults (aged < 50 years) in multiple high-income western countries in contrast with stabilising or decreasing trends in incidence in older adults (aged ≥50 years). This study aimed to investigate contemporary colorectal cancer incidence trends in younger adults versus older adults.

METHODS: Colorectal cancer incidence data, including year of diagnosis, sex, and 5-year age group for 50 countries and territories, were extracted from the WHO-International Agency for Research on Cancer Cancer Incidence in Five Continents Plus database. The Human Development Index 2022 was retrieved from the United Nations Development Programme and grouped into very high (>0·80), high (0·70-0·79), medium (0·55-0·69), and low (< 0·55) categories. Age-standardised incidence rates (ASR) per 100 000 person-years of early-onset (diagnosed between ages 25 to 49 years) and late-onset (diagnosed between ages 50 to 74 years) colorectal cancer (ICD 10th revision, C18-20), diagnosed between 1943-2003 and 2015-17, were calculated using the direct method and Segi-Doll world standard population). The primary study objective was to examine contemporary colorectal cancer incidence trends in younger adults versus older adults using data until 2017 from 50 countries and territories. Temporal trends were visualised and quantified with joinpoint regression, stratified by age at diagnosis (25-49 years or 50-74 years). Average annual percentage changes (AAPC) were estimated.

FINDINGS: In the most recent 5 years (2013-17 for all countries analysed, except for Japan [2011-15], Spain [2012-16], and Costa Rica [2012-16]), …

Extreme Value Theory Analysis Of High Emitter Trends Across Four Us Cities From 1995 To 2021, M. Matti Maricq, Gary A. Bishop

Fuel Efficiency Automobile Test Publications

Extreme value theory provides a direct means to characterize the distribution of high emitters within a vehicle fleet and calculate statistical confidence intervals for comparisons. Defining a “high emitter” as the maximum emitter in a random sample of N vehicles implies in the limit of large N that high emitters follow an extreme value distribution, comprised of three distinct domains. The analysis of over twenty years of roadside remote sensing emissions measurements in Chicago, Denver, Los Angeles and Tulsa reveals clear differences between gasoline vehicle high emitter distributions across pollutants (hydrocarbons (HC), carbon monoxide (CO) and nitric oxide (NO)), but …
