The attempt to elucidate the biological function of enzymes involved in the biosynthesis of tetrahydromethanopterin for the use in one‐carbon metabolism by archaea and select bacteria has resulted in the crystal structure of the hypothetical protein A2617 from Methylibium petroleiphilum . The structure was initially s…
At present, there is limited knowledge about the gastrointestinal fate and potential cytotoxicity of ingested inorganic nanoparticles. In this study, we determined the influence of particle size and concentration of gold nanoparticles (AuNPs) on their intestinal absorption, accumulation and cytotoxicity. AuNPs with di…
With its unique properties, single layer graphene (SLG) has been considered as an outstanding candidate for many possible future applications in nano-electronics as well as in ultrafiltration. This has triggered considerable interest in the investigation of its electronic structure, and possibilities to modify this st…
Guanine is the most susceptible DNA base that can be oxidized because it holds the lowest oxidation potential value in comparison to the rest of the DNA bases. Due to the formation of radicals in the guanine base, the stability of the damaged DNA is often compensated with the formation of DNA‐protein crosslinks. DNA‐p…
Ras GTPase is involved in a number of signaling pathways that are responsible for the control of many cellular processes, including cell proliferation. Ras functions like a molecular switch, where its inactive form binds to GDP and its active form binds to GTP. We had shown through crystallography work that in its act…
Gram‐negative bacteria tightly regulate intracellular iron, an essential nutrient. To ensure this strict control, some outer membrane TonB‐dependent transporters (TBDTs) responsible for iron import stimulate their own transcription in response to extracellular binding of ferric siderophore. This process is mediated by…
Ras GTPase is involved in cell‐signaling pathways that control cell proliferation, differentiation, and apoptosis. There are three main isoforms of Ras, H‐, K‐, and N‐Ras, which share about 95% sequence identity in their soluble domain. They have very similar three‐dimensional folds, however they have been suggested t…
This paper assesses the feasibility of producing fuel energy from sewage sludge via four processes: microwave-induced pyrolysis/gasification and conventional pyrolysis/gasification. Both pyrolysis and gasification produced gas, char, and tar. The gas produced for the gasification contained mainly hydrogen and carbon m…
This work demonstrates a simple approach of developing electrochemical heavy metal ions sensor by employing calix[4]arene on indium tin oxide (ITO) electrode. The method involves the formation of self-assembled monolayers (SAMs) of 3-aminotrimethoxysilane (APTMS) on ITO, acting as a template for calix[4]arene attachme…
In the present paper, we have reported the room temperature growth of (Sb0.2Bi0.8)2S3 thin films by dip method and annealed at various temperatures. The films were deposited from a reaction bath containing antimony chloride, glycine and sodium thiosulphate. We have analyzed the electrical, thermoelectrical and photoel…
Cleaning up the environment and, more importantly, preventing pollution volutions for worrying problems, approaching responsible research studying risk and precaution. Scientific organizations as IUPAC and the Organization for are important issues in today's world. There is the necessity for science to provide Economi…
En los últimos años, se ha implementado de manera muy activa la búsqueda de diferentes estrategias para el aprovechamiento de recursos lignocelulósicos logrando potenciar materias primas y generando productos renovables. Uno de estos productos son las nanofibras de celulosa (NFC), las cuales resultan en agregados de c…
Front Cover: A redox-driven switch between wrinkled and dewrinkled states on polyaniline film is presented. This switch is derived from the reversible transition between the redox states of polyaniline (e.g., emeraldine salt/leucoemeraldine base or emeraldine salt/pernigraniline base) that are involved in different re…
Back Cover: A novel aromatic diamine having both reactive amine groups and a directly thermo-polymerizable benzocyclobutene moiety is used to modify the properties of the conventional polyimides, making a great improvement of the properties of the polyimides. Further details can be found in the article by Yijie Luo, J…

The KTM control system consists of three control subsystems. The first VCHS is designed for heating and keeping the temperature properly inside the chamber and its branch pipes at a level of 200 ± 10ºC during the pumping-out and purifying.
Searching for structurally very similar molecules is a relatively new direction in structure-property-activity studies, which is gaining momentum in view of considerable interest in screening huge combinatorial libraries for a few structures of great similarity to selected standards. Such explorations will undoubtedly…
Objective: To evaluate and correlate between shear bond strength and nanoleakage at resin dentin interface of three adhesive systems after 24hours and 6 month of water storage.Materials & Methods: Twenty four freshly extracted sound human molars were selected for shear bond test. The occlusal surface of each tooth was…
This paper investigated the applicable possibility of PTT and wool staple fibers to the air vortex system as high quality yarns for a high emotional and comfort garment. It was found that the tactile hand of vortex yarn knitted fabrics was harsher than ring and compact yarns knitted fabrics. It was observed that forma…
