Abstract Activity at the NASA Langley Research Center (LaRC) has focused on developing low density polyimide foam and structures which are made using monomeric solutions or salt formed from reaction of a dianhydride diamine dissolved in mixture foaming agents alkyl alcohol room temperature. Monomer blends may be used to make variety foams with varying properties. The first process developed consisted thermal cycling polymer precursor residuum allowing inflation particles interact create...
Summary Understanding how intra-tumoral immune populations coordinate to generate anti-tumor responses following therapy can guide precise treatment prioritization. We performed systematic dissection of an established adoptive cellular therapy, donor lymphocyte infusion (DLI), by analyzing 348,905 single-cell transcriptomes from 74 longitudinal bone-marrow samples 25 patients with relapsed myeloid leukemia; a subset was evaluated protein-based spatial analysis. In acute myelogenous leukemia...
In this work, we have used transmission electron microscopy (TEM) to study Co6S8(PPh3)x-pillared MoS2 and directly observed that the Co clusters can either intercalate into bulk or bind defect sites at edges of MoS2. A distribution discrete 0.87 nm scattering centers has been assigned remnants Co6S8(PPh3)6 clusters. On basis X-ray diffraction (XRD) studies, a lattice expansion 1.48 was expected if triphenylphosphine ligands remained intact. The centers, however, consistent with for Co6S8...
Modulating the host response, including accumulation of oxidized lipid species, is important for improving tissue engineered vascular graft (TEVG) viability. Accumulation lipids promotes smooth muscle cell (SMC) hyper-proliferation and inhibits endothelial migration, which can lead to several current challenges small-diameter TEVGs. Generating biomaterials that reduce oxidation survival this assessment provide a reliable correlation clinical situations. In study, we determined collagen...
Abstract The intracellular membrane domain (IMD) is a metabolically active and laterally discrete initially discovered in Mycobacterium smegmatis . IMD correlates both temporally spatially with the polar cell envelope elongation M. Whether or not similar exists pathogenic species remains unknown. Here we show that conserved structure found tuberculosis We used two independent approaches, density gradient fractionation of domains visualization IMD-associated proteins through fluorescence...
Noncontact atomic force microscopy, commonly referred to as "tapping mode" AFM, has been used scan primarily the morphological features of growing hectorite clay crystallites synthesized in presence organoammonium cations. The use such cations allows larger crystals form this system, making study by AFM feasible. This is first time that temporal "snapshots" a clay's nucleation and crystallization processes have presented. observed view does not support perhaps predicted scene small slowly...
Hydrogen purification membranes have been prepared via a simultaneous electroless plating of Pd and Ag on 0.5 ?m media grade Porous Stainless Steel (PSS). Effects the bath temperature, composition, annealing time temperature were studied while developing coating. Very low but measurable N2 fluxes seen, ranging from 0.010 to 0.020 cm?/cm?-min at temperatures varying 300?C 400?C. As no helium flux was observed, it appears that nitrogen diffused, albeit much more slowly, through same...
ABSTRACTA nominal 1500 STP-L PAssively Cooled, Electrically heated hydride (PACE) Bed has been developed and tested. The bed contained 12.6 kg of a La-Ni-Al alloy used aluminum foam to improve heat transfer within the bed. Steady-state temperature measurements made at constant power showed nonuniform profile. Protium absorption rates were measured pressures 253 kPa, 413 680 kPa with forced convection cooling air flow ranging from 50 150 SLPM air. Absorption tests also performed simulating...
The intracellular membrane domain (IMD) is a subcompartment found in Mycobacterium smegmatis cells. Proteomic analysis of purified IMD identified more than 300 proteins, including enzymes involved cell envelope biosynthesis.
Abstract Sulfide cluster‐derived ensembles are promising models of the active sites in commercial hydrotreatment catalysts. A series sulfide clusters were adsorbed intact onto high‐surface‐area γ‐alumina, magnesium oxide and activated carbon supports, then pretreated to produce highly dispersed catalytic with sizes similar those their precursor clusters. The activities bimetallic catalysts significantly higher than monometallic We took this as evidence that direct interactions between...
Abstract The extrusion of LDPE was simulated under well‐defined conditions by using a Brabender Plasti‐Corder. grades tested according to gel formation were synthesized in modified autoclave reactor. With the basic synthesis same two different reactor pressures used and at both pressures, melt index levels maintained. with lower pressure two‐phase conditions. Plasti‐Corder influence temperature, mixing efficiency, time, as well BHT content investigated. By studying torque, content, change...
Tracheal tube fire is a well recognized complication of airway laser procedures. The use helium in the anesthetic gas mixture delays ignition time polyvinyl chloride tracheal tubes when carbon dioxide used. effects mixtures on potassium titanyl phosphate (KTP) laser-induced have not been studied.One hundred forty unmarked segments were exposed to KTP or beams. Each segment was suspended burn chamber with varying oxygen either nitrogen helium. 21%, 30%, and 40% O2 N2 30% Fourteen tested for...
