An exciting development over the past few decades has been the use of high-throughput computational screening as a means of identifying promising candidate materials for a variety of structural or functional properties. Experimentally, it is often found that the highest-performing materials contain substantial atomic…
The corrosion inhibition of aluminum in 2 M H2SO4 solution by carboxymethyl cellulose (CMC) alone and in combination with iodide ions has been investigated using electrochemical measurements and surface analysis techniques. The results showed that CMC moderately inhibited aluminum corrosion in the H2SO4 solution, and…
Here, we address the issue of finding correct CF 2 /CF 3 area ratios from X-ray photoelectron spectroscopy (XPS) C 1s narrow scans of materials containing −CH 2 CH 2 (CF 2 ) n CF 3 ( n = 0, 1, 2, ...) moieties. For this work, we modified silicon wafers with four different fluorosilanes. The smallest had a trifluoropro…
Abstract Complex metal hydrides provide high‐density hydrogen storage, which is essential for vehicular applications. However, the practical application of these materials is limited by thermodynamic and kinetic barriers present during the dehydrogenation and rehydrogenation processes as new phases form inside parent…
Although much progress has been made in engineering vascular grafts for large- and small-diameter arterial repair or bypass, the extension of these results to the microsurgical size scale has been challenging. Here, we evaluated the use of dense collagen tubes (outer diameter 1 mm, inner diameter 0.5 mm) for vascular…
We revisit the problem of excluded volume deposition of rigid rods of length k unit cells over square lattices. Two new features are introduced: (a) two new short-distance complementary order parameters, called Π and Σ, are defined, calculated, and discussed to deal with the phases present as coverage increases; (b) t…
Patients with cancer suffer from severe side effects and reduced life quality, as chemotherapeutic drugs are cytotoxic toward normal cells as well as toward cancer cells. In recent years, nanoparticles have been explored as targeted drug delivery systems; however, problems such as toxicity and instability prevent thei…
Modern medicine has undoubtedly achieved enormous progress in applying various polymer-based materials for specific applications. Despite this, there is still a need to create systems, especially on the nano-scale, that are simultaneously nontoxic, biocompatible and able to be functionalized with active biomolecules.…
Abstract This study successfully incorporated a short‐segment fluorine‐containing chain extender (2,2,3,3‐tetrafluoro‐1,4‐butanediol [TF]) into castor oil‐based polyurethane (COPU) to synthesize TF/COPUs. The interactions between TF and COPU components were identified by Fourier transform infrared and X‐ray photoelect…
Abstract Agro‐industrial wastes are used as carbon precursors in the production of activated carbon because they are rich in lignocellulosic materials. This study aimed to investigate the relationship between the main characteristics of precursor materials and activated carbons by multivariate analysis. After characte…
Abstract Silicone polymer‐based nanocomposites containing β‐Bi2O3 nanoparticles with varying concentrations of silica nanoparticles are successfully prepared and characterized for thermal stability, surface topography, and X‐ray attenuation property. Of all the samples studied here, silicone polymer of higher density…
Abstract Taxanes are natural anticancer constituents, and the sample preparation from matrix normally depends on organochlorine solvents. In this study, green and natural menthol‐based aqueous deep eutectic solvent was synthesized and used for sample preparation for taxanes. Five key parameters were optimized and the…
Abstract Spent honeycomb biomass as sustainable source is used to generate value added product, such as activated carbon. The generated activated carbon is characterized by X‐ray diffraction, Fourier transformed infra‐red spectroscopy, Raman spectroscopy, Scanning electron microscope, High‐resolution transmission elec…
Abstract The development of photoelectric devices for high integration and miniaturization in the semiconductor industry can be pushed forward by the thriving research of two-dimensional layered metal dichalcogenides (2D-LMDs). SnS 2 nanosheets have an evident photoresponse to both ultraviolet and partial visible ligh…
The morphology and reactivity of mass-selected titania clusters, Ti3O6 and Ti3O5, deposited onto Au(111) were studied by scanning tunneling microscopy and temperature programmed desorption. Despite differing by only one oxygen atom, the stoichiometric Ti3O6 and the sub-stoichiometric (“reduced”) Ti3O5 clusters exhibit…
Curved crystal surfaces enable the systematic and accurate comparison of physical and chemical processes for a full set of vicinal crystal planes, which are probed in the very same environment. Here, we examine the early stages of the CO chemisorption on vicinal Rh(111) surfaces using a curved Rh crystal that exposes…
Coating colloidal particles with DNA is a promising strategy to make functional nanoscale materials because the particles can be programmed to spontaneously self-assemble into complex, ordered structures. In this Article, we explore the phase behavior and types of structures that can be formed when interactions betwee…
Evidence of strong coupling between plasmons and molecular excitons for plasmonic nanoparticle (NP) dimers exhibiting ultra-sensitive surface enhanced resonant Raman scattering is the observation of anti-crossing in the coupled resonance. However, experimentally tuning the plasmon resonance of such dimers for the obse…
Polymer flooding emulsions and microemulsions caused by tertiary oil recovery technologies are harmful to the environment due to their excellent stability. Two cationic hyperbranched polyamidoamines (H-PAMAM), named as H-PAMAM-HA and H-PAMAM-ETA, were obtained by changing the terminal denotation agents to H-PAMAM, whi…
Interatomic forcefields for silicate glasses often rely on partial (rather than formal) charges to describe the Coulombic interactions between ions. Such forcefields can be classified as "soft" or "hard" based on the value of the partial charge attributed to Si atoms, wherein softer forcefields rely on smaller partial…
