Abstract:

Abstract The oxygen transmission rate measurement apparatus for plastic film and sheeting is mainly used to measure the oxygen transmission rate and oxygen transmission coefficient of plastic film and sheeting. Oxygen transmission tests can analyze and solve the problems caused by oxygen, such as oxidation deterioration. At present, there is no relevant calibration specification or method for oxygen transmission rate measurement apparatus for plastic film and sheeting in China. This article presents a novel calibration method to evaluate the measurement accuracy and temperature control perform

Abstract:

Oxygen is an important factor in the wine aging process, and the oxygen transmission rate (OTR) is the parameter of the wood that reflects its oxygen permeation. OTR has not been considered in the cooperage industry yet; however, recent studies proposed a nondestructive method for estimating the OTR of barrel staves, but an efficient method to combine these staves to build barrels with a desired OTR is needed to implement it in the industry. This article proposes artificial intelligence methods for selecting staves for the construction of barrel heads or bodies with a desired target OTR. Genet

The results indicated that the relationship between temperature and the oxygen/water vapour transmission rate of the SPI films followed an exponential grow curve [y=A*exp(x/B) + C].

Abstract:

Highlights Fundamental engineering properties of hermetic bag liners were identified and measured to establish specifications for a new ASABE X657 standard for measurement and rating the performance of gas barrier liners in hermetic storage bags. Results showed strong evidence of differences in properties among six types of commercially available hermetic bag gas barrier liners (P&lt;0.05). Critical gas barrier properties (OTR and WVTR) were measured to assess their ability to maintain initial conditions (“hermeticity”). Critical mechanical properties, such as impact failure weight, penetr

Abstract:

The manuscript presents the barrier properties of Arboblend V2 Nature and Arboblend V2 Nature reinforced by coating granules with silver nanoparticles, regarding the contact angle and oxygen transmission rate. Also, are highlighted compression molding stages used in order to obtain the test samples - thin sheets. Following the obtained results is observed that by using the PVD coating the oxygen transmission ratio is reduced up to 32% compared to the base material. This improvement is due to the small silver nanoparticles that were uniformly deposited on the surface of Arboblend V2 Nature gran

Abstract:

This paper discusses a device for measuring oxygen saturation (SpO2) and heart rate as parameters of the representations of heart conditions. SpO2 device that have been made has a small dimension, wearable and high mobility with battery as the main power source. The device connects to a node MCU as a data processor and an internet network gateway to support internet of things applications. Data sent to the Internet cloud can be accessed online and real time via website for further analysis. The error rate at heart rate measurement is ± 2.8 BPM and for oxygen saturation (SpO2) is ± 1.5%. Testin

Abstract:

Instruments for measuring pulse rate, oxygen saturation, and body temperature for Covid-19 patients have been designed using the MAX30100 sensor and the Internet of Things (IoT)-based MLX90614 sensor. The MAX30100 sensor is used to measure pulse rate and oxygen saturation. A non-contact MLX90614 sensor is used to monitor body temperature, with an ultrasonic sensor used to set the maximum distance between the sensor and the object. The measurement results were transferred to the database via the ESP8266 MCU node's Wi-Fi communication line. The stored data can be accessed via a web browser. Comp

Abstract:

Abstract Lignin, esterified with palmitic and lauric acid chloride, has been studied for the application as coating on fiber-based packaging material. The aim was to improve the barrier properties against water vapor and oxygen of paperboard. The esterification was followed by Fourier transform infrared spectroscopy, 31P nuclear magnetic resonance spectroscopy, and gel permeation chromatography measurements. The lignin esters were applied on paperboard and formed a continuous film. The moisture barrier property of the coated paperboards was characterized by the water vapor transmission rate (W

Abstract:

Corrosion has been responsible for several gas pipeline leakage accidents; thus, clarifying its failure mechanisms is a precondition to prevent such accidents. On the basis of failure analysis of corroded pipe sections, laboratory exposure tests were conducted by simulating three possible corrosion environments inside a gas pipeline. The corrosion rate indicated by depth change was adopted in this study. Scanning electron microscopy and X-ray diffraction were used to analyze corrosion products. Results showed that the specimens completely immersed in condensate water were generally corroded an

Abstract:

Pulmonary dysfunction is a widespread issue, particularly in developing nations. It encompasses restrictive, obstructive, and mixed pulmonary function disorders that lead to a decrease in vital lung capacity, an increase in functional residual capacity, and a decline in blood oxygen concentration and saturation. This study aims to combine oximetry and spirometry into a single device, using the Internet of Things (IoT) technology to display results via a smartphone app. The focus is on analyzing oxygen saturation, with normal levels ranging from 96% to 100% in adults, alongside a heart rate of

Abstract:

Traditionally, to achieve low resistivity and high transmission indium-tin oxide (ITO) films were deposited at elevated substrate temperatures about 400o C. In some cases, films deposited at low substrate temperatures can then annealed at higher temperature to achieve lower resistivity. In this paper thin films of ITO with various oxygen flow rates were prepared by ion-assisted electron beam evaporation at ambient substrate temperature. The electrical and optical properties of ITO thin films have been investigated as a function of oxygen flow rate, rate of deposition and the layer thickness. T

Abstract:

Uniform hexagonal prismatic zinc oxide rods were grown over the entire alumina substrate at 550°C using a two-step oxygen injection process, whether the substrates were coated with a catalyst or not. X-ray diffraction showed that all of the depositions exhibited a preferred orientation in the (002) plane. The influence of oxygen concentration was investigated by changing the oxygen flow rate. Oxygen concentration affected the size of ZnO nanorods, especially the diameter. The ZnO nanorods were further checked using high-resolution transmission electron microscopy, photoluminescence, Raman spec
