“…A polarizer based on lateral leakage loss phenomenon can be very compact, insensitive to dimensional variation, broad band and insensitive to temperature variation as compared to polarizers based on other techniques such as ARROW's [36], [37], metal-cladding waveguides [38]- [40], lithium niobate waveguides [41], or liquid crystals [42]. Since this type of polarizer is a straight waveguide, it is very simple to make and readily integrated with other components in advanced silicon photonic circuits.…”

This paper presents an overview of lateral leakage in silicon photonics due to polarization coupling between the guided mode of a ridge waveguide and unguided slab mode in the etched cladding. We explain the physical origins and provide insight into how this effect can be suppressed or harnessed. We show how lateral leakage can manifest as new resonant behaviour and explore this effect in the context of bound states in the continuum. We review a number of applications for devices based on lateral leakage and present outlook for a new generation of polarization manipulators, antennas and filters. Index Terms-Silicon photonics, optical waveguide, optical resonator, bound states in the continuum.

“…3) Preparation of (E)-tert-butyl 6- (((1-(2-(bromomethyl)phenyl)-2methoxy-2-oxoethylidene)amino) oxy)hexanoate (19). A mixture of oxime 18 (synthesized following the procedure described by Li et al) 47,48 (90 mg, 0.466 mmol), tert-butyl 6bromohexanoate (16, 117 mg, 0.466 mmol), and anhydrous Cs 2 CO 3 (228 mg, 0.699 mmol) in dry DMF (1.7 mL) was stirred under nitrogen for 4 h, poured into water, and worked up as usual using EtOAc to extract. Chromatography of the crude product, using hexane-EtOAc (9:1) as eluent, afforded the corresponding intermediate O-alkylated oxime (141 mg, 83%) as a colorless oil.…”

Kresoxim-methyl was one of the two first strobilurins to be discovered, and nowadays it is widely used as an antifungal agent in crop protection. Because of its low molecular weight and negligible structural complexity, the generation of antibodies to kresoxim-methyl noticeably requires the preparation of functionalized haptens. In this study, the introduction of a hydrocarbon spacer arm at the aromatic moieties of the target molecule was carried out by a convergent strategy based on the Sonogashira cross-coupling reaction, and functionalized linkers of the same length were also tethered to the aliphatic toxophore group by the O-alkylation reaction. Evaluation of the immune response, in terms of antibody affinity, showed a differential behavior among five synthesized haptens whose sole dissimilarity was the derivatization site. The characteristic (methoxyimino)acetate moiety of strobilurins was revealed as the optimum linker position for high-affinity polyclonal and monoclonal antibody production. However, good monoclonal antibodies were isolated from mice immunized with a hapten carrying the linker at an opposite site, which otherwise generated a poor polyclonal response in rabbits. Site-heterology was confirmed as a feasible approach for the improvement of the apparent affinity, particularly with polyclonal antibodies. Several of the monoclonal antibodies generated in the context of this project could be proper binders for kresoxim-methyl immunosensing over different analytical platforms.

“…In fact, 1,3,4‐oxadiazoles are privileged scaffolds in medicinal chemistry. 1,3,4‐oxadiazole structure has been investigated to see that they have antibacterial, [1,2] anticonvulsant, [3,4] anti‐allergic, [5] antifungal, [6,7] antiviral [8] and antidepressant properties [9] . Furthermore, 1,3,4‐oxadiazole motifs are widely used in anticancer drug research [10–15] .…”

An efficient approach to access 2,5‐disubstituted 1,3,4‐oxadiazoles by oxidation of 2‐arenoxybenzaldehyde N‐acyl hydrazones with molecular iodine

An oxidative cyclization of 2‐arenoxybenzaldehyde N‐acyl hydrazones 3 a–o was employed to synthesize new 2,5‐disubstituted 1,3,4‐oxadiazole compounds 4 a–d, 4 f–i, 4 k–n. This method involves oxidative cyclization of 2‐arenoxybenzaldehyde N‐acyl hydrazones 3 a–o with molecular iodine mediated catalysis in which potassium carbonate served as a base. Characterization of all the synthesized novel compounds involved, proton and carbon NMR, mass spectrometry, and CHN elemental analysis. The synthesis of novel 2,5‐disubstituted 1,3,4‐oxadiazoles may display potential to provide pharmacologically important heterocyclic compounds.
