Abstract The universal response of Escherichia coli to stress is enhancing the synthesis of specific histone-like Dps proteins that bind bacterial DNA. As a result, two-dimensional and three-dimensional crystalline arrays can be observed in the cytoplasm of starving bacteria. Conditions for obtaining in vitro co-cryst…
To determine optimal values for behavior of cathodic protection stations in extended and areal objects is an essential problem with the solution allowing to keep up normalizable values of protective and polarized potentials within the limits that can be specified. The article analyses approaches to identification of o…
Yarns with natural-synthetic hybrid fibers are becoming increasingly popular with the increase of environmental awareness. This is mainly because the hybridization of fiber may reduce the use of synthetic fibers in the making of yarns. Note that polyester, an excellent synthetic fiber, is difficult to be recycled and…
Les nanoparticules de bismuth métallique sont peu décrites dans la littérature et pourtant elles ont un fort potentiel médical. Leur utilité est notamment décrite dans des applications thérapeutiques et/ou diagnostiques De plus, le bismuth est un élément abondant, peu cher et biocompatible. Dans ce projet, une synthès…
Purpose: This study was designed to determined the changes of inorganic components in Hanwoo cow bone (shank, sacrum, feet and miscellaneous) according to the different extraction times of bone broth. Method: The extraction time of bone broth was up to 14 hours, and the broth was sampled every 2 hours. The macro (Na,…
The organic-inorganic hybrids of polyurethane (PU) and boron nitride (BN) modified with magnetite (Fe3O4) were prepared to investigate the effect of BN orientation under a magnetic field for enhancing the thermal conductivity of PU. The introduction of magnetite could be proved through scanning electron microscopy (SE…
Shape memory polyurethanes (SMPU) is one of the most notable and common shape memory polymer (SMP), and its composites has gained attention due to the enhancement in both shape memory and mechanical properties. In addition, as the awareness of sustainable development, environmental issues, and fossil fuel depletion, p…

Future trends push TES towards higher temperatures to increase solar-to-electricity conversion efficiency and novel storage materials are often considered the only viable option. To date these candidates suffer from either high costs (carbonate salts containing Li+) or severely attack structural materials (chloride sa…
Οι ημιαγωγικές νανοδομές, όπως τα νανονήματα (NWs) και οι νανολωρίδες (nanofins), έχουν αποκτήσει σημαντικό ενδιαφέρον ως πολλά υποσχόμενα στοιχειώδη δομικά στοιχεία σε νανοηλεκτρονικές και νανοφωτονικές εφαρμογές. Οι μειωμένες τους διαστάσεις και ο υψηλός λόγος αναλογιών (aspect ratio) θα μπορούσαν να ευνοήσουν τη συ…

Irresistible confusions and significant liquid misfortune can prompt stun or even passing after injury, wound dressings are constantly required for better treatment1,2. Albeit a few dressings have been created, some are not powerful in eliminating microorganisms or controlling different circumstances, while some are h…
Thermoelectric materials have the unusual but highly desirable property of converting between heat and electricity. While their poor efficiencies have so far limited them to niche applications such as space exploration, they have great potential for waste heat recovery. Recent years have seen the demonstration of larg…
iber composite materials have great applications for the building and construction industries. The main objective of fiber-reinforced composites is to obtain materials with high strength together with a higher elastic modulus. In this work, composite materials of fibers were built as reinforcing agents in slip as a ce…
Activated carbon was synthesized from bamboo charcoal by KOH activation at various temperatures for electrochemical double layer capacitor applications. The micro-structural and surface properties of all the samples were characterized by X-ray diffraction, scanning electron microscopy and N2 adsorption/desorption isot…
Τα εκτοξευόμενα πυροπροστατευτικά υλικά (Sprayed Fire-Resistive Materials (SFRM)) είναι μια κατηγορία υλικών που χρησιμοποιούνται για την παθητική πυροπροστασία μεταλλικών δομικών μελών. Τα υλικά αυτά μπορεί να εμφανίσουν βλάβη όταν το δομικό μέλος υποβληθεί σε μηχανικές παραμορφώσεις, με αποτέλεσμα να επηρεαστεί η απ…
Avancees recentes en nanotechnologie ont conduit au developpement de nanomateriaux magnetiques tels que des nanoparticules d'oxyde de fer (Fe3O4) utilisees comme nanoaporteurs dans des applications de liberation de medicaments et considerent ces nanoparticules comme des candidats a la liberation de monoxyde d'azote (N…
Pada komponen mesin industri dituntut untuk memiliki kualitas yang baik dimana memiliki berat yang ringan namun memiliki sifat material yang kuat, tahan terhadap korosi dan dapat menahan beban yang besar, sehingga dapat menunjang produksi industri tersebut. Salah satu cara yaitu dengan pengecoran logam, banyak jenis p…
