    Abstract Bi 2 S 3 -containing nanocomposites have attracted considerable attention due to their outstanding photocatalytic activity. However, little study was focused on the preparation and PL property of core-shell (BiO) 2 CO 3 @Bi 2 S 3 nanowires. Herein we report the in situ preparation, characterization and PL property of (BiO) 2 CO 3 @Bi 2 S 3 core-shell nanowires. (BiO) 2 CO 3 @Bi 2 S 3 core-shell nanowires with different sulfur content were synthesized in situ by irradiating (BiO) 2 CO 3 nanowires in xanthate solution. These nanowires showed strong photoluminescence (PL) emission from violet to blue light range. The XRD patterns, EDS mapping images, HRTEM images, and XPS results demonstrated the formation of Bi 2 S 3 shell on the surface of (BiO) 2 CO 3 core. SEM and TEM images indicated that the core-shell nanowires were 20–40 nm in diameter and up to tens of micrometers in length. The sulfur content in core-shell nanowires increased from 0.31% to 1.13% with increasing reacted times. EDS mapping showed that S element was uniformly distributed on the surface of nanowires. The PL peaks at 395, 418, 441 and 467 nm of (BiO) 2 CO 3 @Bi 2 S 3 core-shell nanowires with low S concentration were contributed to the intrinsic emission of (BiO) 2 CO 3 core, Bi-containing intermediate-induced emission, BiO cluster-induced emission, and surface defect-induced emission of (BiO) 2 CO 3 core, respectively. A new shoulder peak at 427 nm appeared in the PL spectrum of (BiO) 2 CO 3 @Bi 2 S 3 core-shell nanowires with 1.13% S, which could be contributed the electronic coupling effect between Bi 2 S 3 shell and (BiO) 2 CO 3 core. We anticipate that the core-shell nanowires will find use in photochemical and photo-electronic fields. Highlights Core-shell (BiO)2CO3@Bi2S3 nanowires are prepared and characterized in detail. (BiO)2CO3@Bi2S3 nanowires show strong PL emission from violet to blue light range. The sulfur content in (BiO)2CO3@Bi2S3 core-shell nanowires affect their PL emissions. The growth mechanism of the core-shell nanowires relies on the ion-exchange reaction.

    Abstract NiAl-LDHs with tunable acid-base sites were fabricated by hexamethylenetetramine(HMT) hydrolysis method, and acid-base sites were probed in synthesis of furfural diethyl acetal from furfural and ethanol. XRD, FT-IR, XPS, EXAFS, PALS, NH 3 -TPD, Pyridine-IR, ICP/AES and CHN element analysis were used to investigate the composition, structure, and origination of the acid-base activity sites of NiAl-LDHs. The result showed that nitrate intercalated LDH (marked as NiAl-NO 3 -LDH) and carbonate intercalated LDH (marked as NiAl-CO 3 -LDH) could be tunably fabricated under different synthetic pH. The acid-base sites of NiAl-CO 3 -LDH and NiAl-NO 3 -LDH presented significant difference. NiAl-NO 3 -LDH expressed preferable acid catalytic property with fine acid activity sites. However, NiAl-CO 3 -LDH presented inert activity in the acid catalysis reaction due to the absence of appropriate acid activity sites. Further investigations proved that the appearance of proper oxygen vacancy arising from low coordination Ni 2+ in NiAl-NO 3 -LDH contributed to the establishment of Lewis acid sites. Accordingly, the intrinsic law of synthetic pH orienting the establishment of acid-base activity sites was revealed. Highlights NiAl-NO 3 -LDH and NiAl-CO 3 -LDH were purposefully fabricated by HMT hydrolysis. Proper acid-base activity sites were tunably established on NiAl-LDHs. Acidic sites stemming from low coordination Ni 2+ in NiAl-NO 3 -LDH were confirmed. The inherent law of pH orienting the establishment of activity sites was revealed.

    Abstract We present the preparation of polyaniline/Ni 0.5 Zn 0.5 Fe 2 O 4 (PANI/NiZn ferrite) nanocomposite. The preparation process consists of two steps: First, the ferrite is synthesized by self-combustion technique using sucrose as fuel. Then, the process is continued by in-situ chemical oxidative polymerization of aniline in the presence of the ferrite. Three different weight ratios of PANI/NiZn ferrite (1:2, 1:1, and 2:1) are prepared and structurally characterized by SEM, XRD, FT-IR and UV-vis spectroscopy. The functional characterization is performed by measuring the dc-conductivity, and microwave absorption characteristics in the range (8–12 GHz). XRD patterns prove the formation of the spinel ferrite, while SEM analysis indicates that the change in PANI/NiZn ferrite ratio has an effect on the morphology, which eventually influences the microwave absorption characteristics of the composite. A maximum reflection loss of −39.56 dB at 11.0 GHz with a matching thickness of 2.5 mm and a bandwidth of 3.0 GHz is obtained for PANI/NiZn ferrite having a weight ratio of 1:1 with only 25%w/w load in paraffin. Highlights PANI/NiZn ferrite nanocomposite is prepared with three different weight ratios. There is a link between the morphology of the samples and the reflection loss (RL). Best RL is achieved for PANI/NiZn ferrite weight ratio of 1:1. RL: −44.23 dB at 12.1 GHz, thickness: 2.25 mm, bandwidth:1.65 GHz.

    Abstract This paper outlines the synthesis and characterization of NiO, CdO and NiO-CdO nanocomposites prepared by a simple soft chemical route. The thermal behavior, structure, surface morphology, elemental composition of the synthesized samples was characterized by TG-DTA, XRD, SEM, EDX and XPS analyses. The various functional groups present in the samples were identified by FTIR analysis. Photoconductive and antibacterial studies were performed to find the suitability of the composite in photoconductive sensor and pharmaceutical applications. Thermal studies confirm that the thermal decomposition of NiO, CdO and NiO-CdO nanocomposites occur at 332.9 °C, 325.8 °C and 334.5 °C, respectively. XRD studies confirm that the NiO and CdO nanopowders exhibit cubic crystal structure and diffraction peaks related to NiO and CdO were observed in the composite. The EDX and XPS spectra confirmed the presence of Ni, Cd and O in the composite. The optical and photoconductive results confirmed that the composite has properties intermediate between NiO and CdO nanopowders. The NiO, CdO and NiO-CdO nanocomposites showed enhanced antibacterial activities against S. aureus and K. pneumonia bacteria strains. Highlights NiO, CdO and NiO-CdO nanocomposites were synthesized by a simple soft chemical route. Enhanced photoconductive properties were observed for the NiO-CdO nanocomposite. The composite showed enhanced antimicrobial efficiency compared to that of NiO.

    Abstract Our aim in the present research work is to investigate the crystallization kinetics and phase transformation studies in Se 85 In 15-x Sb x semiconductor. DSC measurements were done at constant heating rates of 5, 10, 15, 20 and 25 K/min for Se 85 In 15-x Sb x alloys. The glass transition (T g ), on-set crystallization (T c ) and peak crystallization (T p ) temperature were found to be increases with heating rate for all samples. The activation energy for glass transition (ΔE g ) and crystallization (ΔE c ) were calculated by different approaches and found to be nearly identical. Thin films of Se 85 In 15-x Sb x alloys were prepared by the thermal evaporation technique and the effect of thermal annealing on optical properties were discussed by means of optical absorption measurements. The optical band gaps were found to decrease with annealing temperature. This decrease in optical band gap can be associated with phase change in Se 85 In 15-x Sb x alloys from amorphous to crystalline phase. Highlights Chalcogenide glasses have wide range of technical applications. The investigation of Se 85 In 15-x Sb x has significant applications in electronic devices. The phase transformation study gives remarkable information. HRXRD and FESEM have been used for structural studies. The outcome shows the possible applications in different technical devices.

    Abstract A systematic study of the high-pressure effect on the pyrolysis of solid α-amino acids L-leucine (C 6 H 13 NO 2 ), L-alanine (C 3 H 7 NO 2 ), L-aspartic acid (C 4 H 7 NO 4 ) and glycine (C 2 H 5 NO 2 ) is presented. The experiments were performed at 7.7 GPa during 1 min in the temperature range from 300 to 800 °C. The effect of the pyrolysis under high pressure on the electronic structure of carbon and nitrogen was investigated by X-ray photoelectron spectroscopy (XPS). The effect on the atomic bonding configuration was studied by infrared and Raman spectroscopy. The obtained results suggested that the thermal decomposition of amino acids under pressure at 300 and 400 °C started with dehydration followed by polymerization. For temperatures above 600 °C it was observed the formation of graphite-like structures functionalized with nitrogen and oxygen atoms. Highlights Pyrolysis of α-amino acids at 7.7 GPa during 1 min was studied from 300 to 800 °C. XPS, Raman and FTIR spectroscopy were used to investigate the samples. From 300 to 500 °C pyrolysis lead to the formation of aliphatic of cyclic structures. Above 500 °C, defective graphitic structures containing N and O were formed. High pressure avoided the complete volatilization of the amino acids. Graphical abstract [DISPLAY OMISSION]

    Abstract Mass transfer and chemical reactions in nanoscale particles under the assumption of the size dependence of the cohesive energy or the influence of the Laplace pressure are considered. A comparison of the above-mentioned approaches is given. It is shown that the use of the first or second of the above-mentioned approaches can lead to a difference in the dependence of the rates of the aforementioned processes on the nanoparticle size. The influence of the confinement of ionic liquids within nanopores of supported ionic liquid membranes on the separation of gas mixtures is discussed. Considered regularities can be used for clarifying the physical mechanisms of the size effects, which take place in systems with nanoparticles and nanopores, and for the intensification of some processes in chemical engineering and nanotechnology. Highlights Size effects in nanoparticles and confined ionic liquids are considered. Lower cohesive energy in nanoparticles increases rate of chemical reaction. Laplace pressure in nanoparticles decreases rate of chemical reaction. Confined ionic liquids in nanopores affect gas mixture separation.

    Abstract The unique properties of Gemini surfactants and their variety of applications encouraged many researchers to synthesize more of these compounds. Herein, we constructed new cationic Gemini surfactants by using aromatic spacers with different chain lengths. The critical micelle concentration value for each surfactant was determined using the electrical conductivity measurements. The variety of aggregation behaviors of Gemini surfactants was studied by using atomic force microscopy, which encouraged us to use these surfactants in the preparation of mesoporous silica NPs. Our results indicated that we have succeeded in finding a new soft-template for preparing uniform small size hollow spheres mesoporous silica NPs of a diameter depending on the used surfactant. Moreover, we investigated the effect of pH value on the morphology of the prepared silica, which indicated that using of acidic media resulted in the formation of hollow micro-particles instead of hollow NPs. Furthermore, the anti-corrosion efficiency of these surfactants in comparing with cetyltrimethylammonium bromide (CTAB) as a positive control was investigated by monitoring the corrosion rate of iron sheets in 0.5 M of hydrochloric acid based on weight loss method. Our results indicated that all the prepared Gemini surfactants possessed higher anti-corrosion efficiency at very low concentrations than CTAB surfactant. Highlights New cationic Gemini surfactants with different spacers/tails were constructed. The CMC for each surfactant was determined using the electrical conductivity. The Gemini surfactants were used as soft-template for hollow spheres MSNs. The size of the obtained silica is depending on the spacer length and pH value. Our Gemini surfactants showed higher anticorrosion efficiency than CTAB. Graphical abstract [DISPLAY OMISSION]

    Abstract Superhydrophobic transparent thin films using Mn doped zinc oxide (Mn/ZnO) and polystyrene (PS) composites have been synthesized successfully by chemical solution method. The nanocomposites thin films were fabricated by using Mn/ZnO and PS mixture in toluene, followed by film casting on glass substrate. For a comparison ZnO nanoparticles thin film was also prepared with PS. Mn/ZnO nanostructures have been synthesized by hydrothermal method using hexamethylenetetramine (HMTA) as a capping agent. The XRD analysis shown that the development of hexagonal wurtzite structure of Mn/ZnO with preferred (101) orientation. SEM analysis shown that Mn/ZnO nanorods have been uniformly dispersed in the PS matrix. Water contact angle (WCA) was found as 107° and 151° for the ZnO@PS and Mn doped ZnO@PS thin film, respectively. The transparency of the Mn doped ZnO@PS films are also large (∼90%) as compared to ZnO@PS film (∼80%) which is attributed to enhanced energy band gap of ZnO after Mn doping. The larger contact angle (WCA ∼151°) in the Mn/ZnO@PS thin film has been recognized to the rough surface of PS thin film due to the presence of Mn/ZnO nanorods. The present process is very simple and embrace ability for extensive applications for making super hydrophobic transparent surfaces. Highlights ZnO and Mn doped ZnO nanoparticles have been synthesized by hydrothermal method. Structural and optical characterizations of the synthesized Mn doped ZnO nanoparticles thin films have been done. The Mn doped ZnO@PS nanoparticles thin film showed excellent stability, transparency and super-hydrophobicity.
