The immunochemical analysis of Daudi Ia molecules by a variety alloantisera led to the recognition at least three molecular species carrying different antigenic determinants: DRw6, DC-1, and DC-2. Genetic as well structural evidence indicates that DRw6 DC-1 are controlled separate, HLA-linked loci, rather than alleles same locus. alloantigenic determinants appear be expressed on small subunit. DC-2 discussed had not been defined serological population level, but were demonstrated present level.

11,000-Dalton common portion fragments derived from HL-A antigen molecules were isolated and found to have a significantly high homology β 2 -microglobulin in amino-acid composition. Common are also very similar with respect molecular size, charge, distribution tissues. Moreover, both the spent culture media of human cell lines plasma urine. Thus it appears that may well be same substance as fragment molecules.

A novel supramolecular nanoarchitecture, comprising C(60)/Co porphyrin nanosheets, was prepared by a simple liquid-liquid interfacial precipitation method and fully characterized means of optical microscopy, AFM, STEM, TEM, XRD. It is established that the highly crystalline nanosheets have (1:1) stoichiometry, when incorporated in bottom-gate, bottom-contact field-effect transistors (FETs), they show ambipolar charge transport characteristics.

The regioregular highly head-to-tail-coupled poly(3-alkylthiophene) (HT-P3AT) films were prepared by a friction-transfer technique. Polarized UV−vis absorption spectroscopy and grazing incidence X-ray diffraction (GIXD) used to study the polymer molecular arrangement in friction-transferred HT-P3AT films, scanning electron microscopy (SEM) was observe film surface morphology. polarized spectra show large dichroism regarding drawing direction of friction-transfer. order parameter is evaluated...

We analyzed the crystallization process of CH3NH3PbI3 perovskite by observing real-time X-ray diffraction immediately after combining a PbI2 thin film with CH3NH3I solution. A detailed analysis transformation kinetics demonstrated fractal diffusion solution into film. Moreover, crystal was found to be initially oriented based on orientation but gradually transition random orientation. The fluctuating characteristics perovskites, such as penetration and orientational transformation, should...

A liquid-crystalline polymer, poly(9,9-dioctylfluorene) (PFO), was found to form highly oriented films by a friction-transfer technique. The polarized UV−vis absorption and photoluminescence spectra of the formed showed strong dichroism with dichroic ratio approximately 10 in drawing direction friction transfer. Subsequent thermal treatments friction-transferred PFO were specifically effective for improvement physical properties, structure, morphology films. By rapid slow cooling from melted...

Three distinct molecular subsets with different structures and alloantigenic determinants were identified in human Ia antigens from cells of an HLA-Dw7 homozygous cell line. The carried DR7 specificity, BR4X7 supertypic specificity MB2 respectively, immunospecifically separated by the use operationally monospecific alloantisera. These specificities showed HLA-linked segregation families they distributed population according to but partially overlapping patterns. On peptide mapping analysis,...

Polarized polymer light-emitting diodes (PLEDs) have been constructed utilizing friction-transferred poly(9,9-dioctylfluorene) (PFO) thin films. The friction transfer technique allows oriented PFO to be deposited directly onto an indium tin oxide anode without alignment layer such as polyimide. absorption and photoluminescence spectra revealed that the backbones are highly aligned in direction. We fabricated PLEDs consisting of emissive layer, vacuum-deposited bathocuproine electron...

Uniaxially oriented films of β-phase poly(9,9-dioctylfluorene) (PFO) were realized by a friction-transfer technique followed thermal annealing and vapor treatments. Absorption photoluminescence (PL) spectra show the characteristics β-phase: an additional absorption peak at 433nm redshifted PL peaks compared with those usual nematic (N) phase. We fabricated polarized polymer light-emitting diodes utilizing PFO. Highly emission integrated polarization ratio 51 was observed from devices. The...

SUMMARY The soluble HL-A-active substances found in plasma have been investigated using a radioimmunoassay to determine their HL-A alloantigenic activities, such as HL-A1 and HL-A2, the common activities that are characteristic of number antigens. Plasma, which accounts for about 10% particular activity can be measured whole blood, contains series molecular fragments related antigens different sizes appear degradation products cell membranes. Gel filtration yields three fractions carrying or...

Epitaxial growth of thiophene/phenylene co-oligomers(e.g., see Figure) on uniaxially oriented poly(p-phenylene) (PPP) is reported. The emission properties these co-oligomer thin films are investigated and compared to those grown quartz. Color-tunable highly polarized along the direction orientation PPP observed in former case, while isotropic occurs quartz substrate.

We demonstrated the polymer field-effect transistors (FETs) utilizing regioregular poly(3-alkylthiophene)s (P3AT) films prepared by a drawing method. The P3AT film exhibited large optical dichroic ratio, which originated in backbones aligned to direction. In-plane anisotropy and enhancement of FET characteristics have been observed that are caused molecular alignment. In case poly(3-dodecylthiophene), hole mobility along direction was enhanced factor 25 compared with spin-coated film.

Abstract Summary: The formation of a molecular‐complex crystalline phase syndiotactic polystyrene (sPS) that contains stable nitroxide radical compound, 2,2,6,6‐tetramethylpiperidinyl‐ N ‐oxyl (TEMPO), is confirmed by IR and electron spin resonance (ESR) spectroscopy, X‐ray diffractometry, thermogravimetric analysis.
