Abstract Protonated salts and charge-transfer complexes of the 1,3- and 1,6-diazaphenalene (DAP) systems 5–7 have been investigated for new conducting molecule-based materials. Cyclic voltammetry measurements revealed that DAP derivatives are stronger electron donors than hydroquinone, and some of them possess compara…

New chiral Schiff bases with a 1,3,4‐thiadiazole unit in the rigid core were synthesized (SB1–SB4). These compounds contain a chiral chain derived from (S)‐isoleucine and (R)‐2‐octanol. Their liquid crystalline properties were studied by polarizing optical microscopy, differential scanning calorimetry and X‐ray diffra…

Wax (predominantly tricosane paraffin wax, with a melting temperature of 48°C) filled with hexagonal boron nitride (BN) particles (5-11μm) was found to be an effective phase-change thermal interface material. The thermal contact conductance, as measured with the interface material between copper surfaces, decreased wi…

Abstract As a new type of π-conjugated macrocycles, 1,8-anthrylene–butadiynylene cyclic tetramers were synthesized by metal-catalyzed oxidative coupling reactions. The fluorescence spectrum of the nonsubstituted derivative indicated partial formation of an excimer in the excited state. The macrocyclic structure underg…

Degradation of oil painted copper surfaces involves chemical, physical and mechanical processes that are influenced by the prevailing environment. The oil paint/copper interface formed between the lower layers of paint and its copper support determines the stability of the system. Components within the painted copper…

We investigate how miscellaneous parameters influence the velocity of the disclination line in a bistable chiral splay nematic liquid crystal (BCSN LC) device, using a model derived from the relationship of the free energy loss rate with dissipation energy. The disclination velocity is consistently coupled with the fr…

Abstract Application of the ESI‐ mass spectrometry technique for the structural studies of biopoliesters is reported. The structural studies were performed on two selected commercially available biopolyesters i.e. poly(3‐hydroxybutyrate‐ co ‐3‐hydroxyvalerate) (PHBV) and poly(3‐hydroxybutyrate‐ co ‐3‐hydroxyhexanoate)…

We measured the orientational order parameter of $F$-actin traversing the isotropic-nematic phase transition using a combination of techniques, including fluorescence imaging, local birefringence measurements, and small-angle x-ray scattering. The order parameter approaches a saturated value of 0.75 for actin concentr…

Biodegradable copolyesters were prepared by copolymerization of ϵ‐caprolactone (ϵCL) with a cyclic polyester consisting of isosorbide and suberic acid (CPIS). Four initiators were compared: Sn(II)2‐ethylhexanoate (SnOct2) in combination with benzyl alcohol, 2,2‐dimethyl‐2‐stanna‐1,3‐dioxepane (DSDOP) lanthanium and yt…

During operation, an outdoor high voltage insulator may come under various stresses. One of them is environmental pollution, where pollutants stick to the insulator surface. The polluted condition may produce leakage currents or even electrical discharges. Their waveforms are normally non-pure sinusoidal. To understan…

We examine the evolution of the refractive index modulation when recording gratings in an acrylamide based photopolymer. A nonlocal diffusion model is used to predict theoretically the grating evolution. The model has been developed to account for both nonlocal spatial and temporal effects in the medium, which can be…

Extremely high strength in microcomposite Cu-Nb wires is associated with ultra-fine-scale microstructure. The extended interfaces between ribbon-like niobium filaments and copper matrix contain the areas of semi-coherent interfaces that are apparently the main reason of significant level of residual stresses observed…
