Some novel energetic isomeric materials have been designed substituting three nitro groups on each aromatic ring at different positions of N-benzylidenebenzamine. Structure-1 differs from HNS by having an aza-substitution (centric perturbation) at the olefin carbon. The other structures are constitutional isomers of I. By using DFT [B3LYP/6-31 G(d)] approach various MO and ballistics properties of these structures have been calculated and compared with values of HNS and HNAB which are related to 1.

Numerical and Experimental Investigation into LWIR Transmission Performance of Complementary Silicon Subwavelength Antireflection Grating (SWARG) Structures
Cetin, Ramazan; Akın, Tayfun (Springer Science and Business Media LLC, 2019-03-18)
This paper presents a detailed comparison between the long wave infrared (LWIR) transmission performances of binary, silicon based, structurally complementary pillar and groove type antireflective gratings that can be used for wafer level vacuum packaging (WLVP) of uncooled microbolometer detectors. Both pillar and groove type gratings are designed with various topological configurations changing in various period sizes (Delta) from 1.0 mu m to 2.0 mu m, various heights/depths (h) from 0.8 mu m to 1.8 mu m,...
Optical and mechanical properties of fiber-reinforced ceramic matrix optically transparent composites
Dericioğlu, Arcan Fehmi (2001-12-01)
The idea of increasing the fracture resistance of optically transparent Ceramics by incorporation of continuous fibers with a small expense in their light transmission was applied to a SiC (SCS-6) fiber-reinforced magnesium aluminate spinel matrix composite. It was found that although there is a slight decrease in the light transmittance of the transparent monolithic matrix with increasing fiber volume fraction, a fail-safe mechanism appeared in the composite by the bridging effect of the intact fibers
Synthesis and characterization of conjugated polymers with polyhedral oligomeric silsesquioxane pendant groups
Ertan, Salih; Kaynak, Cevdet; Cihaner, Atilla; Department of Polymer Science and Technology (2017)
In this thesis, a series of monomers covalently bonded to polyhedral oligomeric silsesquioxane (POSS) pendant group was designed and synthesized. POSS group is a hybrid organic-inorganic nanostructure with 1 to 3 nm diameter. POSS which has a cage structure is mainly composed of silicon (Si) (at vertices) and oxygen (O) (in the middle of the edge). POSS nanostructure can be modified through the vertices with organic functional groups. POSS groups provide different properties, such as thermal robustness, mec...
Adsorption of hydrogen and oxygen on single and double layer stepped Si(100) surfaces
Salman, SA; Katırcıoğlu, Şenay; Erkoc, S (2001-06-30)
We have investigated the electronic band structure of hydrogen and oxygen adsorbed single and double layer stepped Si(100) surfaces by Empirical Tight Binding (ETB) method. The total electronic energies of the H,O-S-A, D-A, D-B type stepped Si(100) systems are calculated with limited number of hydrogen and oxygen atoms separately to find out the most probable adsorption sites of the adatoms in the initial stage of hydrogenation and oxidation.
Topological defects in liquid crystals as templates for molecular self-assembly
Wang, Xiaoguang; Miller, Daniel S; Büküşoğlu, Emre; de Pablo, Juan Jose; Abbott, Nicholas L (2016-01-01)
Topological defects in liquid crystals (LCs) have been widely used to organize colloidal dispersions and template polymerization, leading to a range of assemblies, elastomers and gels. However, little is understood about molecular-level assembly processes within defects. Here, we report that nanoscopic environments defined by LC topological defects can selectively trigger processes of molecular self-assembly. By using fluorescence microscopy, cryogenic transmission electron microscopy and super-resolution o...
