Frontier concept of rabi chip for intelligent humanoid

The sequence of the human brain can be configured by the originated strongly coupling fields to a pair of the ionic substances(bio-cells) within the microtubules. From which the dipole oscillation begins and transports by the strong trapped force, which is known as a tweezer. The tweezers are the trapped polaritons, which are the electrical charges with information. They will be collected on the brain surface and transport via the liquid core guide wave, which is the mixture of blood content and water. The oscillation frequency is called the Rabi frequency, is formed by the two-level atom system. Our aim will manipulate the Rabi oscillation by an on-chip device, where the quantum outputs may help to form the realistic human brain function for humanoid robotic applications.

Syringolin A is a non-ribosomal virulence factor secreted by few Pseudomonas strains. Syringolin A is an well known irreversible proteasome inhibitor and antitumor compound. The present study is focused on the extraction of Syringolin A through a non-tedious and economical process. Syringolin A is extracted from culture supernatants by the immiscible organic layer by mixing of dichloromethane or chloroform (trichloromethane). Syringolin A was identified by the characteristic peak at 350 nm by UV spectra. The compound was further characterized by Thin Layer Chromatography (TLC) with the retention value, Rf was found to be in the range of 0.78-0.83 run using a combination of solvent systems water and methanol. The molecular weight of the compound was found to be 492.2614 g mol-1 identified and analyzed by UHPLC–QTOF-MS analysis. Due to its significant pharmacological importance in proliferative diseases, further studies on production and optimization of these compounds are necessary.

Investigation of thermometrical optical characteristics influence on spectral thermometry metrological characteristics

The complex of investigations of optical characteristics of controlled objects and spectral symmetric-wave and two-colour compensating thermometry (SWT and TCCT) influence on their errors of method and instrumental errors is performed. Advantages of these new methods in the field of errors of method, in comparison with known spectral and also classical energy and spectral ratio thermometry are proved. It is established that right use of the SWT and the TCCT, which takes into account thermometrical conditions, allows to completely exclude methodical and instrumental components from the errors of optical temperature measurements. Spectral thermometry is based on remote quantitative determination of the spectral emissivity distributions of controlled objects. Using these distributions and well-known relationships between the spectral coefficients of emission, absorption, reflection and transmission we can determine macro-optical characteristics of these objects and remotely investigate them.

Spectral studies on inclusion complexation between 3-hydroxyflavone and 2-Hydroxypropyl-β-cyclodextrin

3-hydroxy-2-phenylchromen-4-one (HF) is a flavonols that is formed when hypoxanthine is attached to a ribose ring (also known as a ribofuranose) via a β-N9-glycosidic bond. Cyclodextrins are able to form host-guest complexes with hydrophobic molecules given the unique nature imparted by their structure.As a result, these molecules have found a number of applications in a wide range of fields. The inclusion complex of HF with 2HP-β-CD is prepared by various synthetic method such as physical method (PM), kneading method (KM) and co-precipitation method (CP). The solid inclusion complex is characterized by UV, luminescence spectra, Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) and powder X-ray diffraction (XRD). The anticancer activity of the solid complex is performed against breast cancer cell line and it is noticed that there is no much better activity than the HF alone. Both the HF and its solid complex showed the poor anticancer activity against MDA MB 231 cell line.

Preparation and Photocatalytic Properties of Ag2CO3 / Graphene Composite Photocatalyst

Silver-based photocatalytic semiconducting materials have drawn the attention of reseachers for their high visible photocatalytic activity. However, the silver-based photocatalytic semiconducting material exhibits light corrosion during the photocatalytic reaction, and the photocatalytic stability is poor. Therefore, improvingthe photocatalytic stability and inhibition of light corrosion of silver-based photocatalytic semiconductor materials have been the focus of attention. In this paper, according to the principle of photocatalysis and the principle of photo-corrosion, it is proposed to improve the photogenerated electrons and hole separation of photocatalytic semiconductor materials, to rapidly transfer photogenerated electrons, to inhibit photogenerated electrons and Ag + to prevent light corrosion, Stability of the catalyst. Ag2CO3 / GO composite photocatalytic materials were synthesized by precipitation method using polystyrene as photocatalyst. The characterization and photocatalytic performance tests showed that the graphene has a good auxiliary effect, which can promote the separation of photogenerated electrons and holes of Ag2CO3 and transfer the photogenerated electrons into O2 in H2O in time, thus suppressing the light of Ag2CO3 / GO photocatalytic materials Corrosion phenomenon, improve the photocatalytic performance. Ag2CO3 / GO-1.0 has the best catalytic activity for the catalytic activity and stability of Ag2CO3 / GO in the photocatalytic decomposition of methyl orange. Therefore, graphene as a photocatalytic auxiliaries can effectively improve the photocatalytic stability of silver-based photocatalytic materials and have some reference significance for improving the stability of other photocatalytic materials which are prone to light corrosion.

Comparison of Wet Deposition and Plasma Deposition of Aluminosilane Coatings

Silane coatings are suitable for various applications of metal surfaces, such as forming a corrosion protection layer or as a primer for subsequent coating. In this work, bis-1,2- (triethoxy) ethane (BTSE) was used as a precursor on a 99.99% aluminum substrate for deposition of the coating, with three diff erent techniques: dipping (water-based solution ), Vacuum plasma and atmospheric plasma. (IRRAS), X-ray photoelectron spectroscopy (XPS) and fi eld emission gun scanning electron microscopy (FE-SEM) were used to characterize the structure, composition and surface morphology of silane coating. The purpose of this study is to compare the surface and body properties of membranes prepared by three different methods to obtain information on how BTSE molecules are modified by deposition techniques. The results show that in addition to the more traditional wet dip coating, the film can also be vacuum and atmospheric plasma deposition. The vacuum plasma deposition layer can be considered as an organic and inorganic mixture, which can be obtained by dipping as well as the silane layer. However, atmospheric plasma treatment leads to the formation of more inorganic fi lms containing Si-O. Photon spectroscopy and infrared spectroscopy showed the presence of Si-O-Si bonds, while IRRAS measurements showed Si-O-Si, Si-O-C, Si-O and Si-CH3 absorption bands.
