Some novel symmetrical bis(pyrrolo[2,3-d]pyrimidinyl)methanes were synthesized via diheteroarylation of sp3 CH bond of acetophenones with molecular iodine and DMSO. Further, an efficient reaction protocol was developed with which both symmetrical and some novel unsymmetrical bis(pyrrolo[2,3-d]pyrimidinyl)methanes were…
Non-linear loads, such as switched mode power supply, adjustable-speed drives, arc furnaces, etc., result in deterioration of power quality in terms of current harmonics and reactive power demand. Shunt active power filters are widely used to compensate the current harmonics, thereby improving power quality. Digital s…
We demonstrate the application of polystyrene-functionalized gold nanorods (AuNRs) as a platform for surface enhanced Raman scattering (SERS) quantification of the exogenous cancer biomarker Acetyl Amantadine (AcAm). We utilize the hydrophobicity of the polystyrene attached to the AuNR surface to capture the hydrophob…
We have developed a highly tunable, narrow band far-infrared (FIR) photodetector which utilizes the characteristic merits of graphene and two-dimensional electron gas (2DEG) in GaAs/AlxGa1−xAs heterostructure in the Quantum Hall states (QHS). The heterostructure surface is covered with chemical vapor-deposited graphen…
Fullerenes and their structure and stability have been a major topic of discussion and research since their discovery nearly 30 years ago. The isolated pentagon rule (IPR) has long served as a guideline for predicting the most stable fullerene cages. More recently, endohedral metallofullerenes have been discovered tha…
This work presents a new model for the form factor of a star polymer consisting of self-avoiding branches. This new model incorporates excluded volume effects and is derived from the two-point correlation function for a star polymer. This model is compared with small-angle neutron scattering measurements from polystyr…
Rattan is one of natural resources of Indonesia which contains 30%-40% cellulose. Its high cellulose contents makes it very potential as a source of microcrystalline cellulose (MCC). In this research, manau rattan was characterized by using the Chesson methods. Microcrystalline cellulose was prepared by using two meth…
Between 0.2 and 2000 MHz, the ultrasonic attenuation spectra of oligomer melts have been measured at 25 °C. The oligomers comprise ethylene glycols with eight different mean degrees [Formula: see text]of polymerization (1 ≤ [Formula: see text] ≤ 13.2), a poly(propylene glycol) ([Formula: see text] = 16.9) and three po…
By varying the radio frequency-bias power in an inductively coupled CF4plasma, we have modified the nanoscale morphology and chemical bond structure of polyethylene terephthalate (PET) surface. Specifically, the ion impingement increased the surface roughness and created CFn (n= 2, 3) functional groups on the PET surf…
Novel percolative PZN − PZT / Ag ferroelectric composites with intragranular structure were prepared with micro‐ PZN − PZT and nano‐ Ag particles. The typical core–shell nanostructures were systematically investigated by TEM , in which, the nanoscale shells act as interlayers between the Ag cores and the ceramic matri…
Cobalt selenide clusters with 2-bromo-5-diethylphosphinothiophene (1) and 2-bromo-5-diphenylphosphinothiophene (2) ligands are described. The phosphine ligands are obtained via lithium halogen exchange of 2,5-dibromothiophene followed by addition of chlorodiethylphosphine and chlorodiphenylphosphine, respectively. The…
Integrated microfluidic power generation and power delivery promises to be a disruptive packaging technology with the potential to combat dark silicon. It essentially consists of integrated microchannel-based electrochemical “flow cells” in a 2D/3D multiprocessor system-on-chip (MPSoC), that generate electricity to po…
Silicon nanoparticles embedded in a mesoporous SiO 2 /SiO x matrix have been prepared by pyrolysis of condensed hydrogen silsesquioxane vesicles.
Fe layers with thicknesses between 5 and 100 nm were sputtered on mesoporous nanostructured anatase TiO2templates. The morphology of these hybrid films was probed with grazing-incidence small-angle X-ray scattering and X-ray reflectivity, complemented with magnetic measurements. Three different stages of growth were f…
The solid–liquid phase equilibrium and solubility of 3,5-dichloroaniline were determined in mixed solvents of (methanol + water) and (ethanol + water) in temperatures ranging from (278.15 to 303.15) K under normal pressure (0.1 MPa). The solubility of 3,5-dichloroaniline in the mixed solvents increased with increasing…
Data on corresponding solid–liquid equilibria of sulfanilic acid in different organic solvents are essential for industrial design and further theoretical studies. In this study, the solubilities of sulfanilic acid were measured in methanol, ethanol, 2-propanol, acetone, acetonitrile, formic acid, and acetic acid with…
Bandgap engineering in a single material along the axial length of nanowires may be realized by arranging periodic twinning, whose twin plane is vertical to the axial length of nanowires. In this paper, we report the effect of twin on photoluminescence of ZnSe nanowires, which refers to the bandgap of it. The exciton-…

Magnetic nanoparticles (MNPs) were synthesized and coated with tetraethyl orthosilicate and aminosilane to create functional amino groups. Moxifloxacin (MXF) was conjugated to the modified MNPs using glutaraldehyde as crosslinker. Finally, MXF conjugated magnetic nanoparticles were radiolabeled and their biological af…
Sodium niobate NaNbO 3 hydrate ( NN ‐hydrate) particles with a plate‐like morphology were prepared at 140°C for 2 h in 12 mol/L of NaOH by the hydrothermal method. Bar‐like Na 8 Nb 6 O 19 ·13H 2 O particles were synthesized at as low as 100°C for 2 h. This work demonstrates that by carefully optimizing the reaction co…
