With the rapid development of nanotechnology in recent decade, novel DNA and RNA delivery systems for gene therapy have become available that can be used instead viral vectors. These non-viral vectors made a variety materials, including inorganic nanoparticles, carbon nanotubes, liposomes, protein peptide-based as well nanoscale polymeric materials. They advantages over decreased immune response, additionally offer flexibility design, allowing them to functionalized targeted specific sites biological system with low cytotoxicity.gene keeps hopes life treatment wide range diseases such cancer, nano particles are now known promising carriers effective safe genes cells or tissues. This could provide alternative therapies conventional approaches use viruses carriers. The expression genetic material DNA, into tissues has raised considerable therapeutic diagnostic purposes. But getting nucleic acids cell also faces challenges. challenges less non-virus drug method than free therefore considered risky more appropriate. expanding nonverbal carriers, we will look at few these penicillin, PEI, PLGA, silica, block copolymer, Quantum dot, gold particles, common tubes. Problems include polymer solid lipid investigated. Gene-based is intentional modulation treat pathological conditions. accomplished by introducing exogenous mRNA, small interfering (siRNA), microRNA (miRNA) antisense oligonucleotides. Given large size negative charge macromolecules, their typically mediated In this Review, introduce barriers vivo discuss advances sciences, acid chemistry yielded systems, some which currently undergoing testing clinical trials. diversity highlights progress gene-based using approaches.

Phenolic resins have excellent dimensional, thermal, chemical and corrosion resistance. Also, the volatile substances produced during thermal degradation of this resin low toxicity and, in addition, they high charring. been applied many areas such as internal parts war planes, structures used marine platforms, flame retardant plastics carbon/carbon composites due to having mentioned favorable properties. In article, phenolic samples Resole reinforced with carbon fibers graphene nanoparticles were prepared. last decade, development new polymer nanocomposites has grown significantly. contrast conventional common composites, a feature which filler that size less than 100 nm at least one dimension is used. One advantages it gives several properties primary polymer, despite fact creates limitations its processability other reinforcements. The key these features design behavior nanocomposites, includes nanoparticle interface between matrix. Nowadays, engineering applications, necessary combine materials, not possible use type material satisfies all desired For example, aerospace industry, there need for materials strength, lightness, wear resistance good ultraviolet light do lose their strength temperatures. Since difficult find above properties, better look method solution composite materials.

in this paper, two novel Composites zinc phosphate/Polyvinyl alcohol (ZnP-PVA) and Zinc Phosphate/Polyvinyl alcohol/Carboxymethyl cellulose (ZnP-PVA/CMC) had been synthesized by a low-temperature one-step ultrasonic-template assisted route. For characterization of samples, Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Transmission (TEM), Fourier-transform infrared spectroscopy (FTIR), Energy Dispersive X-Ray Analysis (EDAX), MIC/MBC EIS were used. FTIR spectra the composite confirmed functional groups present PVA/CMC/Zn2+ ions infraction also SEM TEM images showed composites have layered structure with rectangular microcrystals (2.8 mm width ZnP-PVA was able 100% to completely remove bacteria tested sample. As results show, Anti-corrosion efficiency inhibitor is 92.8% at 2 h, 70.6% 4 68.0% 24 h aslo ZnP-PVA/CMC 67.7% 45.6% 50.5% 24h, has investigated.

in recent years, most researchers are trying to seek out and develop effective comparatively simple methods for producing nanostructures. In this regard, the of manufacturing self-regulated nanostructures with alternating arrays given special attention. The anodization, which ends up within formation a porous metal oxide layer consisting an everyday array nanoporous, is one such method. numerous applications aluminum, research on anodization has focused more metal. Anodic corundum may be key sample material creating like nanowires, nanotubes. anodic alumina samples, easy ultimately leads high-density parallel nanoporous. During paper, final structure anoxic further because growth mechanism presence electrical field therefore Penetration Electrolyte species into layer, furthermore as explaining expansion steady state hexagonal plasma membrane structure. Affecting geometric parameters pore diameter, interpore distance, wall thickness, also Thickness Barrier Layer discussed.

Motile microorganisms play a central role in ecosystems both natural habitats and laboratory settings. Their contribution to nutrient cycling is crucial their impact on human health can be significant. Furthermore, they are promising various biotechnological applications. Ongoing studies of microbial motility represent dynamic evolving field research with profound implications for our understanding biology, ecology, environmental science. The thermal properties the base material extremely advanced enable wide range industrial, technical process applications due radiation, variable heat transfer activation energy. Researchers still working hard find renewable energy sources that economical environmentally friendly.

In This study, three new surface-modified antibacterial and anticorrosive nanocomposites (zinc Phosphate- Polyvinyl Pyrrolidone, Zinc Pyrrolidone/Hydroxy Apatite Apatite/Alginate) were synthesized in low-temperature by facile efficient method. We crosslink Alg with Zn2+ Ca2+ to make it insoluble enhancing of their physical biological properties Apatite/Alginate). Nanocrystals characterized (XRD), (FT-IR), (EDX), (SEM) (TEM). the TEM image showed that core shell nanocrystal had good dispersion a particle size 8–36, 12–38 10–45 nm, respectively. Antibacterial rate Apatite/Alginate NPs reached near 100%. To analyze EIS results obtained from equivalent circuits, parameters such as Rct, CPEdl, Rf, n, CPEf, Rt extracted. Nyquist diagrams demonstrated sample better protection than Pyrrolidone sample, at all immersion time. The phase angle (-θ 11°/96 h) was greater value compared Alginate 10°/96 4.2°/96 h), indicating transition capacitive inductive behavior longer times.

Sustainability and lack of resources both outline need for energy storage tactics, materials, devices. In fact, is nowadays the most important, at same time challenging feature in under development developing countries. Renewable energies are focused as minimizing consumption, whereas maximizing energies. Geopolitical features together with wars middle-east Europe borderline criticize such important topic more more. Rechargeable batteries have widely been served developed continuously electronic devices a means storing electrical energy. Therefore, increasing capacity life has become target researchers working this field. Enlargement application performance windows possible by era nanotechnology, that new generations rechargeable enjoy from much higher efficiency respect to first-generation ones. article, after examining electrochemical preparations, their types discussed.
