An innovative chemical vapor sublimation and deposition (CVSD) process was shown to produce nanoscale anisotropic hybrid materials. Taking advantage of controlled thermodynamic properties and the mass transfer of molecules, this process allowed for water vapor sublimation from an iced template/substrate and stagewise vapor deposition of poly-p-xylylene onto the sublimating ice substrate. In this study, the use of sensitive soybean agglutinin (SBA) protein tubes was demonstrated as an example to prepare the anisotropic hybrid material based on the CVSD process. The rationale of a timing parameter, Δt, was controlled to program the sublimation of the SBA-ice templates and the deposition of poly-p-xylylene during the CVSD process. As a result of this control, a stripping stage occurred, during which SBA tubes were exposed on the particle surface, and a subsequent encapsulation stage enabled the transformation of the ice templates into a nanometer-sized anisotropic hybrid material of poly-p-xylylene as the matrix with encapsulated SBA tubes. The timing parameter Δt and the controlled stripping and encapsulating stages during CVSD represent a straightforward and intriguing mechanism stemming from physical chemistry fundamentals for the fabrication of hybrid materials from sensitive molecules and with predetermined sizes and asymmetrical shapes. A simulation analysis showed consistency with the experimental results and controllability of the timing mechanism with predictable particle sizes.

AbstractWe investigated the fabrication of a 3D colloid crystal assembled in a layer-by-layer fashion on a template substrate. This method of assembling an ordered structure offers flexibility in the choice of crystal orientation, because of the template, and the capability to insert a “defect” layer to introduce defect modes in the stop bands of the crystal. The assembly of layers of 4.4 νm polystyrene microspheres on the patterned (100) substrates was studied using a combination of evaporation and chemical binding. It was observed that the ordering process depends on the physical parameters of the template such as well size and depth. A good adhesion of the beads to the template required chemical functionalization of the substrate.

In construction process, the formwork must be in contact with concrete to help the concrete solidify and fix the shape. Coating the formwork with a polymer can prolong its service life by reducing the amount of concrete sticking to the mold. Herein, an aluminum template substrate was coated with polyvinylidene difluoride (PVDF) or polyurethane (PU). Aluminum template material analysis was conducted, polymer film thickness was measured, and weather, moisture, pollution, salt spray, abrasion, impact, and acid and alkali resistance tests were conducted, as were tensile, bending, adhesion, hardness, and salt water resistance tests. Cement adhesion resistance was repeatedly tested. The experimental results indicated that the PVDF-coated template was superior. The novel PVDF Aluminum template exhibited high corrosion resistance and can be used in building materials, for example, in ceilings, partition walls, curtain walls, roof panels, and roof trusses. For reference, it can also be applied to ship structures and seaside and wind power generation projects.

ABSTRACT The L74V and M184V mutations in the reverse transcriptase (RT) gene of human immunodeficiency virus type 1 (HIV-1) are frequently associated with resistance to the nucleoside reverse transcriptase inhibitors abacavir, didanosine, and lamivudine. Yet viruses containing any of these mutations often display hypersusceptibility to zidovudine (ZDV). Two distinct mechanisms have been described to explain HIV-1 drug resistance. One of these involves diminished rates of incorporation of the nucleotide analogue by mutated RT, while the other mechanism involves increased rates of phosphorolytic excision of the drug-terminated primer. To understand the biochemical mechanisms responsible for the hypersensitization of L74V-containing viruses to ZDV, we studied the efficiency of excision of ZDV-monophosphate (ZDV-MP)-terminated primers by recombinant wild-type and mutated HIV-1 RTs in cell-free assays. We observed that the L74V mutation in RT caused reductions in ATP-dependent removal of ZDV-MP from newly synthesized viral DNA. In addition, we determined that the L74V and M184V mutations did not affect the ratio between the populations of RT-DNA/DNA complexes found at pre- and posttranslocational stages; however, they might have affected proper alignment between incorporated chain terminator and pyrophosphate donor, substrate orientation, affinity for ATP, and/or primer-template substrate. Finally, we confirmed previous findings that L74V-containing viruses display diminished replication capacity and that this is associated with reduced levels of synthesis of early reverse-transcribed viral DNA molecules.
