Hypertension treatments with the ability to reduce endothelial dysfunction while lowering blood pressure are desirable.Leonotis leonurus is a South African plant commonly used for different medicinal purposes, including the treatment of hypertension.The antioxidant scavenging effects of the aqueous leaf extract of L.…
We demonstrate the possibility to fabricate wire structures composed by arranged magnetic particles using pulsed laser deposition (PLD) in the presence of a magnetic field. Ablation of Ni and Co targets was performed in air by nanosecond laser pulses delivered by a Nd:YAG laser system oscillating at 355 nm. Due to the…
ISHS VIII International Postharvest Symposium: Enhancing Supply Chain and Consumer Benefits - Ethical and Technological Issues Use of thermosonication for inactivation of E. coli O157:H7 in fruit juices and fruit juice/reconstituted skim milk beverages
This study deals with the development of a novel technique for formation of advanced Ag nanostructures (NSs) to be applied to high-resolution analyses based on surface enhanced Raman scattering (SERS). It has direct bearing on human health and food quality, e.g., monitoring small amount or traces of pollutants or unde…
Hydride materials, used in hydrogen storage technologies, in powder form can be an explosion hazard and testing these materials using standard techniques is difficult. Research reported in this paper is an attempt to develop numerical methods to obtain explosion properties of such materials. In this work a one-dimensi…
A microstructured polymer film on top of tungsten trioxide (WO3) allows for locally confined insertion of protons (green) from a liquid electrolyte and electrons from a transparent conducting oxide. The formation of atomic hydrogen (red) is accompanied by electrochromic coloration. The diffusive transport of hydrogen…
Abstract The aim of the presented work is to develop improved concepts for the prediction of fatigue lifetime under variable amplitude loading including plastic deformation and thermomechanical fatigue of welded joints made of the austenitic stainless steel 1.4550. Local strain amplitudes are located in the regime of…
In article number 1702182, Jooho Moon and co-workers develop efficient perovskite solar cells based on silver nanowire transparent electrodes with a protection layer of amorphous aluminum doped zinc oxide. This composite electrode shows high optical transmittance of 88.6% and low sheet resistance of 11.9 Ω sq−1. When…
Low firing temperature and excellent gyromagnetic properties such as high remanence square ratio and narrow ferromagnetic resonance line width are required for the application in nonreciprocal microwave ferrite devices based on low temperature cofired ceramics (LTCC) technology. In this research, Bi 2 O 3 -Li 2 CO 3 m…
For using graphene in practical applications, translation of unique and individual properties of graphene flakes into the macroscopic, ordered materials is crucial. The physical and chemical properties of macroscale graphene structures are closely related to the size of graphene flakes as building blocks. However, the…
The knowledge about the formation of hot cracking in magnesium alloys, such as in twin-roll cast magnesium sheets and strips, is fundamental for a good quality of the strips during the further processing by rolling or welding and minimize the reject. Hot cracking often occurs in the so-called mushy zone, when solid ph…
Graphene decorated with hierarchical CuS nanoplates (CuS NP-G) was synthesized using a microwave method to be used as a photocatalytic material. The incorporation of graphene into hierarchical CuS nanoplates was confirmed by structural, morphological and optical characterizations. The photocatalytic performance of the…
Municipal solid waste (MSW) is a widely available large volume source of lignocellulosic material containing a waste paper/cardboard mixture which can be converted into fermentable sugars via cellulolytic enzyme hydrolysis in a sugar platform biorefinery. Thermal pretreatments are generally applied to MSW to facilitat…
The gamma ray shielding properties of cement paste containing ilmenite and barite (BaSO4) at different concentration were investigated using beam transmission method for 59.5 keV gamma ray energy of 241Am radioactive isotopes by using NaI(Tl) scintillation detector. The mass attenuation coefficients (μm) of these shie…
In this study, porous carbon made from coffee bean waste (CBW) was carbonized at 500 °C, 600 °C, and 700 °C to find effective temperature. It is verified from the IR spectrum that carbonization process at certain temperature can effectively break cellulose bonding and make aromatics functional group while preserving i…
Abstract We succeed in the crystallization of hydrogenated amorphous silicon (a-Si:H) films by flash lamp annealing (FLA) at a low fluence by intentionally creating starting points for the trigger of explosive crystallization (EC). We confirm that a partly thick a-Si part can induce the crystallization of a-Si films.…
Как известно, для испытаний на кратковременную и длительную прочность жаропрочных титановых и никелевых сплавов, применяемых для лопаток и дисков компрессора, в основном используются стандартные образцы диаметром 5 мм и расчетной длиной 25 мм. В конструкции газотурбинных двигателей применяются лопатки небольших размер…
A novel high-pressure belt-type die with a split-type cylinder is investigated with respect to extending its lifetime and improving its pressure bearing capacity. Specifically, a tungsten carbide cylinder is split into several parts along the radial direction with a prism-type cavity. In this paper, the cylinders with…
ABO3 perovskite ceramics due to their chemical nature and size difference of the cations A (where A is a divalent metal) and B (where B is a tetravalent metal) have non-centro-symmetric polymorphs and display significant piezoelectric properties. One path to improve piezoelectric properties is through alloying these m…
In this study, the certain chloromethylated polysulfone ultrafiltration membrane (CMPSF) was prepared via nonsolvent-induced phase separation (NIPS) method. Then the hydrophilic monomer was grafted on the CMPSF membrane through quaternary amination reaction. The structure of membrane was characterized by Fourier trans…
