In this paper, we present a novel hybrid material consisting of multiwalled carbon nanotubes (MWCNTs) and molybdenum disulfide (MoS[Formula: see text] with enhanced photoresponsivity in the near-infrared (NIR) region. MoS 2 nanosheets are obtained through chemical exfoliation in NMP solvent, and MWCNTs are grown on these nanosheets using the chemical vapor deposition (CVD) technique. The combination of the NIR transparency of MWCNTs and the high UV light absorption of MoS 2 leads to a substantial increase in the photoresponsivity ([Formula: see text] of the MoS 2 @MWCNTs hybrid compared to bare MoS 2 specifically in the NIR region. Experimental results demonstrate a remarkable enhancement of [Formula: see text] from 18.6 [Formula: see text]A/W to 155.7 [Formula: see text]A/W in the hybrid material, whereas the opposite trend is observed in the case of bare MoS 2 .

The synthesis of metallic nanoparticles has ignited intense interest over the last decade due to their unique properties, which make them applicable in a variety of fields of science and technology. In this study, iron oxide nanoparticles (Fe 2 O 3 NPs) were synthesized, characterized, and their antibacterial activity was determined using a low-cost and simple method. Method: In this paper, magnetic nanoparticles were synthesized by a physical method of pulsed laser ablation in a liquid medium with 600 mJ energy. Magnetic Fe 2 O 3 NPs were prepared by using a 1064 nm Nd-YAG laser and bombarding the [Formula: see text]-Fe 2 O 3 target in a deionized aqueous solution. An absorption spectrometer was used to study the optical properties and structures of nanoparticles, the prepared nanoparticles were analyzed using Fourier transform infrared (FTIR) spectroscopy. Besides, utilizing FESEM, the morphological and surface characteristics were examined. The antibacterial activity of Fe 2 O 3 NPs against several pathogenic Gram-positive and Gram-negative bacteria isolated from various human infection sites was investigated using a disk diffusion experiment with laser pulse lengths of (100 nm, 150 nm, 200 nm and 300 nm) with the same laser energy. Result: The results showed the success of this method as the first sign that can be inferred from the change in the color of the solution to prepare nanoparticles. Fe 2 O 3 NPs are mostly spherical in shape, with nano sizes ranging between 66.7 nm and 9.5 nm. The energy gap was found to be in the range of 1.79–2.39 eV for almost all nanoparticles prepared. Fe 2 O 3 NPs were formed in almost spherical surface morphology with regular size and shape. The results showed their effect on stopping the growth of bacteria of type E. coli maximum zone of inhibition of 20 mm and 19 mm of S. epidermidis, 18 mm of type S. mutans and 16 mm of P. aeruginosa. As a result, in this study, it was shown that Fe 2 O 3 NPs produced in water by laser ablation method can be used as antibacterial agents due to these properties.

Plants’ bioactive chemicals have been utilized throughout human history as supplements and medicines to support the body’s natural physiological processes. When their function is discovered, many substances are added for medical uses. Herbs are known to contain a variety of organic substances. These crucial herbs are the main ingredients in many pharmaceutical and healthcare products. Traditional folk medical practices offer essential information for the extraction and creation of numerous medications and activities as well. The production of a few highly active pharmaceuticals is justified by the extraction and characterization of a variety of bioactive chemicals from green factories. This study uses quantitative analysis of ethyl acetate, ethanol, n-hexane, chloroform and aqueous extract along with established methodologies to assess the phytochemicals. Alkaloids, flavonoids, reducing sugars, proteins, amino acids, saponins, tannins, terpenoids and glycosides were discovered in the quantification and phytochemical screening results. Due to the presence of several phytochemical substances, the entire plant of Psychotria octosulcata W. A. Talbot demonstrated a diversity of medicinal potential. The cytotoxicity activity of the plant extracts was predicted using brine shrimp lethality assay (BSLA). The results showed that the shrimp in the ethanolic extract of Psychotria octosulcata W. A. Talbotare extremely hazardous in higher concentrations. Only 10 shrimps are discovered to be lethal at lowest concentrations even after 24 h. This can be due to the presence of bioactive substances.
纵观人类历史,植物的生物活性化学物质一直被用作补充剂和药物,以支持人体的自然生理过程。当它们的功能被发现时,许多物质被添加到医疗用途中。众所周知,草药含有多种有机物质。这些重要的草药是许多药品和保健产品的主要成分。传统的民间医学实践也为许多药物和活动的提取和创造提供了重要的信息。一些高活性药物的生产是通过从绿色工厂提取和表征各种生物活性化学物质来证明的。本研究使用醋酸乙酯、乙醇、正己烷、氯仿和水萃取物的定量分析,以及既定的方法来评估植物化学物质。在定量和植物化学筛选结果中发现了生物碱、黄酮类、还原糖、蛋白质、氨基酸、皂苷、单宁、萜类和苷类。由于几种植物化学物质的存在,整个Psychotria octosulcata W. a . Talbot植物显示出多种药用潜力。采用盐水对虾致死试验(BSLA)预测植物提取物的细胞毒活性。结果表明,在较高浓度下,对虾类有极大危害。在最低浓度下,即使在24小时后,也只有10只虾是致命的。这可能是由于生物活性物质的存在。

In this paper, photoelectrochemical etching of the n-type silicon (n-Si) wafers is used to prepare porous silicon (PSi) with current density of 10 mA⋅cm[Formula: see text] for 10 min. Moreover, the structural and morphological properties of the n-PSi were analyzed by using XRD and AFM, FTIR and PL. XRD patterns of PSi show that the films are single-crystalline, with cubic structure. The major peak characteristics are allocated to plane (004). The atomic force microscope image and the distribution chart of the grains of the n-PSi displayed that the grain sizes were −8.98. FTIR is a powerful and easy-to-use technique to obtain the surface chemical state of PSi. The convenience results from the transparency of silicon for IR light and the high surface area. The basic features begin from the knowledge of the bondings to hydrogen, [Si–H], and to oxygen [Si–O]. The model calculations sometimes provide useful information in the assignment. By examining FTIR, the active bonds showed the formation of PSi. PL spectra were measured in the range of (600–900) nm, the emission peak for the fixed excitation wavelength at 500 nm, and spectral 1.78 eV and 1.24 eV. PSi is recognized as an attractive building block for photonic devices because of its novel properties including high ratio of surface to volume and high light absorption. We first report NIR and VIS (PDs) fabricated by PSi as a carrier collector and a photoexcitation layer.

Copper oxide was prepared by simple chemical method and deposited on quartz glass and single crystal PSi for solar cell and Photodetector applications by drop casting method. XRD measurements reveal that the film was polycrystalline in nature. The average crystalline size of film was (17.46) nm. In order to investigate the optical characteristics of CuO, researchers took a recording of the transmittance against wavelength. It was determined that the optical energy gap of CuO is equal to 3.5 electron volts. The efficiency of solar cell was (0.27)% and the maximum value of spectral detectivity was 5*10[Formula: see text] (cm Hz[Formula: see text] W[Formula: see text].
