The interaction of nickel nanoparticles with Escherichia coli (E. coli) bacteria has been studied. The nickel nanoparticles have been fabricated by continuous wave laser ablation of nickel target and their properties are studied using different characterization techniques. The antibacterial activity of nickel nanopart…
Abstract An improved power conversion efficiency (PCE) of bulk heterojunction organic photovoltaic cell (OPV) was achieved by inserting an n‐type [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) layer between the active layer and a metal electrode. The controlled substrate temperature was found to be a useful paramet…
In the scale-up of Cu(In1-xGax)Se2(CIGS) solar cell processing for large-area photovoltaics technology, the challenge is to achieve optimum values of layer thicknesses, as well as CIGS Cu stoichiometry and alloy composition x within narrow ranges and simultaneously over large areas. As a result, contactless metrologie…
Thermal fluctuations of nanomagnets driven by spin-polarized currents are treated via the Landau-Lifshitz-Gilbert equation generalized to include both the random thermal noise field and the Slonczewski spin-transfer torque term. By averaging this stochastic (Langevin) equation over its realizations, the explicit infin…
Flavin adenine dinucleotide (FAD) is a cofactor for many enzymes, but also an informative redox active surface probe for electrode materials such as carbon nanotubes (CNTs) and nitrogen-doped CNTs (N-CNTs). FAD spontaneously adsorbs onto the surface of CNTs and N-CNTs, displaying Langmuir adsorption characteristics. T…
The process of modeling photovoltaic devices is a tedious task in that it depends heavily on several intrinsic and extrinsic properties of the material. In this paper, numerical solutions are obtained using the Personal Computer 1 Dimension (PC1D) software package in order to improve solar cells performance. The analy…
We study superconductivity in a Weyl semimetal with broken time-reversal symmetry and stabilized by a point-group symmetry. The resulting superconducting phase is characterized by topologically protected bulk nodes and surface states with Fermi arcs. The topological invariant governing the system is calculated using c…
In low-temperature solution processed amorphous zinc oxide (a-ZnO) thin films, we show the thin film transistor (TFT) characteristics for the trap-filled limit (TFL), when the quasi Fermi energy exceeds the conduction band edge and all tail-states are filled. In order to apply gate fields that are high enough to reach…
The energy gap for electronic excitations is one of the most important characteristics of the superconducting state, as it directly reflects the pairing of electrons. In the copper-oxide high-temperature superconductors (HTSCs), a strongly anisotropic energy gap, which vanishes along high-symmetry directions, is a cle…
Safety and efficacy are of critical importance to any nanomaterial-based diagnostic and therapy. The innocuity and functionality of a nanomaterial in vivo is largely dependent on the physicochemical properties of the material, particularly its surface coating. Here, we evaluated the influence of polycationic coating o…
Folate-modified lipid nanocapsule encapsulated quercetin (QT-FALNC) was prepared with phase inversion method. The formulation was optimized by simplex lattice design with encapsulation efficiency and drug loading as index. The encapsulation efficiency and drug loading of the optimal formulation were 96.01% and 2.98%,…
The number of applications of fluorescence spectroscopy in different areas of chemistry has increased dramatically, in part because a variety of instruments are used to measure fluorescence, including high-throughput microplate readers. Therefore, it is important to introduce students to different instruments. With ma…
The processing of carbon nanotube based nanocomposites is one of the fastest growing areas in materials research due to the potential of significantly changing material properties even at low carbon nanotube concentrations. The aim of our work is to study the curing and thermomechanical behavior of carbon nanotube/epo…
The paramagnetic behavior of 18-electron cyclopentadienylnickel(II) complexes of the [CpNi(μ-Br)] 2 type with two unpaired electrons per metal ion has been investigated by 1 H and 13 C NMR spectroscopy of [Cp‴Ni(μ-Br)] 2 ( 1; Cp‴ = 1,3,4- t Bu 3 C 5 H 2 ), [ 3 CpNi(μ-Br)] 2 ( 2; 3 Cp = 1,3,4- i Pr 3 C 5 H 2 ), and [ 4…
A modified two-step selenization has been demonstrated to overcome inhomogeneous gallium distribution, an issue to lower energy bandgap in the space-charge region as well as cell efficiency. It was found that incorporating selenium into conventional precursors could accelerate the formation of CuInGaSe2 phase in the s…
This paper reports the spatially resolved surface modification of polystyrene (PS) using an atmospheric‐pressure microplasma jet. Treatment of PS surfaces using a microplasma jet with a 100 µm diameter is investigated using contact angle, XPS, AFM and lens epithelial cell (LEC) growth. Microplasma jet treatment create…
Tridentate cyclohexyl-based alkanethiolate SAMs generated from a series of adsorbates of the form R3C6H6(CH2SH)3, where R = -(CH2)nH and n = 3, 8, and 13 (3CnCyTSH), were examined. Characterization of the SAMs by X-ray photoelectron spectroscopy (XPS) revealed that all sulfur atoms of the tridentate adsorbates were bo…
Abstract The photoassisted water oxidation by a range of electrodeposited Al‐modified zinc oxide nanorod arrays (NRAs) has been explored in a standardised photoelectrochemical cell. The nanorods were prepared by electrodeposition onto fluorine‐doped tin oxide glass substrates from warm aqueous solutions of zinc nitrat…
Blended poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(1,4-benzo-{2,1',3}-thiadiazole)] (PFBT)/poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) conjugated polymer nanoparticles were prepared and characterized by conventional and single-particle fluorescence spectroscopy. The particles exhibit red emission…
Hyaluronic acid (HA) is a naturally occurring biodegradable polymer with a variety of applications in medicine. The use of HA as a filler or scaffold for regenerating tissues often requires improving the elastic properties of HA. This is conventionally accomplished via chemical crosslinking, which might require the ge…
