The thermal oxidation characteristics of abietic acid were investigated through tracing the oxidation process in custom-designed mini closed pressure vessel test under isothermal and step temperature ...
Enhancing the fire safety of epoxy resin (EP) concomitant with less mechanical performance degradation is still a challenge for traditional flame retardants. Hence, polypyrrole (PPy) was used as a fil...
Fluoropolymers find applications in heat-resistant cables, chemical-resistant linings, electronic components, cladding materials, and weather-resistant films. Therefore, it is imperative to improve th...
This study reveals how natural fiber welding (NFW) can be used to engineer biopolymer materials with improved thermal stability. First, it is shown how NFW without binders improves lignocellulose yarn...
Corn starch was treated with raw moisture (30%), screw speed (160 rpm), extrusion temperature (30, 55, 80, 105, 130, and 155°C), and emulsifier (1.2%) to produce the starch extrudate particles in a tw...
Total phenolics and anthocyanins in ten samples of Romanian red onion cultivars, extraction optimisation and pH/thermal stability were investigated. Extraction with 80% aqueous ethanol leads to an inc...
Purpose: The objective of the study was to produce copper-based dispersion hardened materials of submicron grain size, determination of their basic functional properties and stability in high tempera...
The aim of the current study is to investigate the reaction of hydroxylapatite with both metallic titanium and titanium oxide, and to examine the e ect of atmosphere on these reactions. For this purpo...
A series of monolayer protected gold nanoparticlecolloidal solutions have been prepared with averagesizes in the 2-15nm range. If a drop of such acolloidal suspension is deposited onto a Si3N4substrat...
The thermal stability of individual glucosinolates within five different Brassica vegetables was studied at 100°C for different incubation times up to 120 minutes. Three vegetables that were used in t...
The microstructure evolution and high thermal stability of the mechanically-alloyed supersaturated nanocrystalline Cu-10%Nb alloy during subsequent heat treatment were investigated by X-ray diffractom...
Purpose: The objective of this work was to investigate the changes taking place in the structure and properties of Ag-La (0.5%) and Ag-mishmetal (1 and 4%) alloys caused by severe plastic deformation ...
Alkaline α-amylase from Bacillus sp. strain KSM-K38 (AmyK38) is a calcium-free enzyme that is stable against chelating and oxidative reagents. Recently, the thermostability of this enzyme was improved...
The thermal stability of sucrose phosphorylase (EC 2.4.1.7) from Streptococcus mutans was enhanced using random and site-directed mutageneses. Random mutagenesis studies revealed that eight single ami...
Solutions (17% TS) of whey protein concentrate (65% protein) were dialyzed against simulated milk ultrafiltrate containing 0 to 9 mM total Ca2+. The dialyzed solutions were heated at 66 or 71°C for 12...
