Control Of Particle Adhesion On InGaAs Surface In Basic Solution By The Addition Of Cationic Surfactant

The adhesion of silica particles on an InGaAs surface in a 1/1/100 NH4OH–H2O2–H2O mixture (APM) solution was investigated. To control the particle adhesion on InGaAs surface, hexadecyltrimethylammonium bromide (CTAB) was added to the APM solution at concentrations of 10-4–10-2 M, and its effect was examined. To understand the adhesion behavior of silica particles on the InGaAs surface in the APM solution with the addition of CTAB, Lifshitz–van der Waals energy, acid–base interaction energy, and electrostatic energy were estimated. In addition, energy barrier was calculated from the changes in those energies. It was found that the behavior of the energy barrier was strongly related to the adhesion behavior of the silica particles on the InGaAs in the APM solution with different concentrations of CTAB. Therefore, the addition of CTAB changes the interaction force and the energy for particle to adhere to the InGaAs surface.

Thermal analysis of heat storage unit equipped with fins employing Galerkin approach

In current study, freezing phenomena within an enclosure with tilted fins has been analyzed. The tank has three cold surfaces and one adiabatic wall and it was filled with NEPCM (mixture of nanoparticles and H2O). To involve the role of style of particles, the conductivity of NEPCM has been estimated according to previous experimental correlation. The formulation of NEPCM properties was based on assumption of homogeneous mixture. Buoyancy term which creates connection between velocity and temperature equations has no sensible impact of solidification. So, energy equation with unsteady source term has been assumed as main equation in current work. Two dimensional tanks have been considered and adaptive grid has been applied. For modeling, finite element method has been implemented and it accuracy was checked according to previous publication. Utilizing the platelet particles instead of sphere can enhance the freezing rate around 5.36% and contours for solid front have been shown this fact, too. Elevating the fraction of particles causes freezing time to decline around 10.74%.

Investigation of evaporation characteristics of ionic liquids/H2O and MWCNT ionanofluids/H2O mixture based on their viscosity and chemical properties

This paper experimentally investigated the evaporation characteristics of [HMIM][BF4], [HMIM][TfO], [HMIM][Tf2N], and [C12MIM][Tf2N] ionic liquids/H2O mixture as well as MWCNT ionanofluids/H2O mixture. The relation between the ionic liquid/H2O mixture evaporation was investigated by analyzing the chemical properties calculated using the Gaussian software package and the experimentally measured viscosity. As a result, H2O was easily evaporated in ionic liquids with low viscosity and a high dipole moment. In addition, as the amount of MWCNT nanoparticles in MWCNT ionanofluid increased and the given pressure decreased, the evaporation rate increased. The 0.5 wt% MWCNT ionanofluid showed higher viscosity than the ionic liquids, and the H2O evaporation flow rate of MWCNT ionanofluid was increased compared to those of the ionic liquids due to the smaller specific heat of MWCNT nanoparticles and the increased heat transfer area. The evaporation characteristics between ionic liquids or ionanofluids and H2O mixtures can be controlled by using the chemical properties and viscosity of the two substances that help to manufacture the optimal working fluid required in the system.

An improved solvent extraction procedure for Re isotopic measurements

In this paper, we present an improved solvent extraction method for the chemical isolation of Re from the sample matrix using ammonia (NH3·H2O) and butanone instead of the traditional extraction method using NaOH and acetone. With this method, no sodium is introduced, and thus, no subsequent further purification is required prior to inductively coupled plasma mass spectrometry (ICP-MS) measurements. For the extraction, when the volume ratio of NH3·H2O to butanone was 1:2, with 4 mL of NH3·H2O and 8 mL of butanone, the recovery was as high as greater than 90%. The effects of the extraction time, the centrifugal speed, and the centrifugal time were investigated. Re can be efficiently extracted into the butanone in only 1 min, and a centrifugal speed of 2000 r/min for 5 min was used to separate the butanone from the NH3·H2O. We compared the three chemical methods (anion exchange resin, acetone–NaOH mixture, and butanone–NH3·H2O mixture) for a variety of sample matrixes (sulfides and rock sample). The results show that the new method can completely separate the Re from the matrix with a low blank (2–5 pg). Finally, the proposed method was verified using reference materials (Henderson HLP, JDC, JCBY, and UB-N), and the analytical results were found to be in good agreement with the previously reported data.

Evaluation of DNA/BSA interaction and in vitro cell cytotoxicity of μ2-oxido bridged divanadium(V) complexes containing ONO donor ligands

Two new μ2-oxido bridged divanadium (V) complexes, [VV2O3(L1,2)2] (1 and 2) have been synthesized using bi-negative tridentate ONO-donor ligands, H2L1,2 (H2L1 = 4-tert-butyl-2-[[[3,5-di-tert-butyl-2-hydroxyphenyl]methylene]amino]phenol and H2L2 = 5-bromo-2-[[[4-(diethylamino)-2-hydroxyphenyl]methylene]amino]phenol). The synthesized ligands and complexes have been characterized through FT-IR, UV‐vis, NMR, and HR-ESI-MS techniques. Single crystal X-ray crystallography data confirmed distorted square pyramidal geometry for both the complexes. The aqueous phase stability of these complexes has been evaluated through HR-ESI-MS in CH3CN:H2O (80:20) mixture. Thereafter their interaction with calf thymus DNA (CT-DNA) have been studied using electronic absorption and fluorescence spectroscopy, revealing an intercalation mode of binding, with binding constant in the order of 104 M−1. Moreover, bovine serum albumin (BSA) interaction of 1 and 2 has been evaluated via fluorescence quenching experiment, which suggests that the quenching mechanism is static (~1013 M−1) in nature. Additionally, the in vitro cytotoxicity of the complexes has been evaluated in human cervical cancer cells (HeLa) (IC50 = 13.57–16.62 μM) and normal mouse embryonic fibroblasts cells (NIH-3T3). The mechanism of cell death brought about by these complexes was studied by nuclear staining, cell cycle and Annexin V/PI double staining apoptotic assay. These studies indicate that 1 and 2 exert inhibitory effects on the S and G2M phase of cell cycle, which is an indication of apoptotic cell death. Also, a clonogenic assay was performed, which showed that the complexes could effectively inhibit colony formation.

Chemical-Phase Equilibrium of CO–CO2–H2–CH3OH–DME–H2O Mixtures in C–H–O Atom-Mol Fraction Space Using Gibbs Free Energy Minimization

This work employs Gibbs free energy minimization to carry out reaction and phase equilibrium analysis for a CO–CO2–H2–CH3OH–DME–H2O mixture, in a manner that enables a compact representation of the mixture’s feed composition in terms of the feed’s C–H–O atom-mol fractions. The concept of the Atom Species Attainable Region (ASAR) is formally defined, and propositions are developed that identify ASAR in C–H–O atom-mol fraction space for feed compositions consisting of either all six or four of the six aforementioned species. Then, Gibbs free energy minimization is carried out for a broad collection of ASAR points and a wide range of temperatures and pressures, aiming to identify conditions favoring DME production. The results of this comprehensive equilibrium analysis are then presented, and conclusions are drawn.

Use of Fe (II) and H2O2 along with Heating for the Estimation of the Browning Susceptibility of White Wine

The aim of the present study was to investigate if the use of Fe (II) and H2O2 (Fenton reaction) along with heating can be implicated for the rapid evaluation of the browning susceptibility of white wine. In this context, increasing concentrations of Fe (II) and H2O2 were added to two white wines (Roditis–Malagouzia and Debina), the samples were stored at 45 °C or 18 °C, and the absorbance at 420 nm (browning index) was measured. Moreover, total sulfur dioxide, total phenolics, flavanols, hydroxycinnamates and total free sulfhydryls were assessed during storage of Roditis–Malagouzia wine samples. The results showed that the addition of Fe (II) + H2O2 mixture in white wines increases rapidly the browning index at 45 °C, indicating the ability to develop a rapid test for the estimation of the browning susceptibility of white wines. Results also showed that the level of flavanols is a suitable index to follow the forced oxidative browning of white wine by adding Fe II + H2O2 at 45 °C. Moreover, results indicated that the levels of total free sulfhydryls may be a suitable index to follow the forced oxidative browning of white wine and in general, white wine oxidation.

Revisiting the Oxidizing Capacity of the Periodate-H2O2 Mixture: Identification of the Primary Oxidants and Their Formation Mechanisms.

This study reexamined the mechanisms for oxidative organic degradation by the binary mixture of periodate and H2O2 (PI/H2O2) that was recently identified as a new advanced oxidation process. Our findings conflicted with the previous claims that (i) hydroxyl radical (•OH) and singlet oxygen (1O2) contributed as the primary oxidants, and (ii) •OH production resulted from H2O2 reduction by superoxide radical anion (O2•-). PI/H2O2 exhibited substantial oxidizing capacity at pH < 5, decomposing organics predominantly by •OH. The likelihood of a switch in the major oxidant under varying pH conditions was revealed. IO4- as the major PI form under acidic conditions underwent one-electron reduction by H2O2 to yield radical intermediates, whereas H2I2O104- preferentially occurring at pH > 7 caused 1O2 generation through two-electron oxidation of H2O2. PI reduction by O2•- was suggested to be a key reaction in •OH production, on the basis of the electron paramagnetic resonance detection of methyl radicals in the dimethyl sulfoxide solutions containing PI and KO2, and the absence of deuterated and 18O-labeled hydroxylated intermediates during PI activation using D2O and H218O2. Finally, simple oxyanion mixing subsequent to electrochemical PI and H2O2 production achieved organic oxidation, enabling a potential strategy to minimize the use of chemicals.

Kinetics of OH + SO&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt; + M: temperature-dependent rate coefficients in the fall-off regime and the influence of water vapour

Abstract. The OH-initiated oxidation of SO2 is the dominant, first step in the transformation of this atmospherically important trace gas to particulate sulfate, and accurate rate coefficients for the title reaction under all atmospheric conditions (pressures, temperatures, and humidity) are required to assess its role in, for example, new particle formation. Prior to this study, no temperature-dependent data were available in the fall-off regime for atmospherically relevant bath gases. We thus address an important omission in the kinetic database for this reaction and highlight significant discrepancies in recommended parameterizations. In this work, generation of OH via pulsed laser photolysis at 248 and 351 nm was coupled to its detection by laser-induced fluorescence to obtain rate coefficients (k1) for the title reaction at pressures of 14–742 Torr (1 Torr = 1.333 hPa) and temperatures of 220–333 K in N2 bath gas. In situ SO2 concentrations, central to accurate kinetic measurements under pseudo-first-order conditions, were measured by optical absorption. Under the conditions of the present study, the termolecular reaction between OH and SO2 is in the fall-off regime, and we parameterized the rate coefficients in N2 in terms of low- (k1,0) and high-pressure (k1,∞) limiting rate coefficients and a broadening factor (FC) to obtain k1,0N2=3.03×10-31 (T/300 K)−4.10 cm6 molecule−2 s−1, k1,∞=2.00×10-12 cm3 molecule−1 s−1, and FC=0.58. The effects of water vapour on the title reaction were explored through measurements in N2–H2O mixtures at 273, 298, and 333 K using the same experimental methods. The rate coefficients are significantly enhanced by the presence of water vapour with k1,0H2O=1.65×10-30 (T/300 K)−4.90 cm6 molecule−2 s−1, which indicates that H2O is a factor &gt;5 more efficient in quenching the HOSO2* association complex than N2. A model-based comparison of our rate coefficients and parameterization with previous literature measurements and recommendations of evaluation panels are presented and discussed. The use of the new parameterization instead of the IUPAC or NASA evaluations, particularly after including H2O as a third-body quencher, leads to a significant (10 %–30 %) reduction in the lifetime of SO2 in some parts of the atmosphere and increases the H2SO4/SO2 ratio concomitantly.

Compact High Efficiency and Zero-Emission Gas-Fired Power Plant with Oxy-Combustion and Carbon Capture

Reduction of greenhouse gases emissions is a key challenge for the power generation industry, requiring the implementation of new designs and methods of electricity generation. This article presents a design solution for a novel thermodynamic cycle with two new devices—namely, a wet combustion chamber and a spray-ejector condenser. In the proposed cycle, high temperature occurs in the combustion chamber because of fuel combustion by pure oxygen. As a consequence of the chemical reaction and open water cooling, a mixture of H2O and CO2 is produced. The resulting working medium expands in one turbine that combines the advantages of gas turbines (high turbine inlet temperatures) and steam turbines (full expansion to vacuum). Moreover, the main purpose of the spray-ejector condenser is the simultaneous condensation of water vapour and compression of CO2 from condensing pressure to about 1 bar. The efficiency of the proposed cycle has been estimated at 37.78%. COM-GAS software has been used for computational flow mechanics simulations. The calculation considers the drop in efficiency due to air separation unit, carbon capture, and spray-ejector condenser processes. The advantage of the proposed cycle is its compactness that can be achieved by replacing the largest equipment in the steam unit. The authors make reference to a steam generator, a conventional steam condenser, and the steam-gas turbine. Instead of classical heat exchanger equipment, the authors propose non-standard devices, such as a wet combustion chamber and spray-ejector condenser.

Time-resolved measurements of HO2 radical in a heated plasma flow reactor

Time-resolved, absolute HO2 number density in diluted H2O2-Ar, CH4O2-Ar, and C2H4O2-Ar mixtures excited by a repetitive ns pulse discharge in a heated plasma flow reactor is measured by Cavity Ringdown Spectroscopy (CRDS). The experimental results are obtained at T = 300–600 K and P = 130 Torr, both during the discharge pulse burst and in the afterglow. The HO2 number density is inferred from the CRDS data using a spectral model exhibiting good agreement with previous measurements of absolute HO2 absorption cross sections. In the room-temperature H2O2 mixture, as well as in CH4O2 and C2H4O2 mixtures over the entire temperature range studied, HO2 is generated only during the discharge burst and decays in the afterglow. However, in the H2O2 mixture at elevated temperatures, T = 400–600 K, HO2 persists in the afterglow up to 10 ms after the discharge burst, comparable with the flow residence time in the reactor. Comparison with kinetic modeling shows that the sustained reactivity after the source of radicals is turned off is due to a chain propagation/ hydrogen oxidation process, which dominates the radical recombination reactions. The kinetic modeling predictions are in good agreement with the relative HO2 number density measured in all three mixtures, although the model underpredicts the absolute number densities in H2O2 at T = 400–600 K by up to a factor of two. Detection of the sustained low-temperature reactivity in H2O2, initiated by the radical generation in the plasma, suggests that the plasma excitation may also affect kinetics of oxidation and reforming of fuels exhibiting low-temperature chemistry below hot ignition point.

Stable Zinc-Based Metal-Organic Framework Photocatalyst for Effective Visible-Light-Driven Hydrogen Production.

Herein, a new Zn-MOF material, [Zn(L1)(L2)], 1, was built successfully through a one-pot solvothermal method. The 3D MOF structure was determined by Single X-ray diffraction analysis, IR, and elemental analysis. A series of PXRD tests of 1 after being immersed in different solvents and pH solutions demonstrated the good stability of 1. Interestingly, this material displayed high catalytic activity for the visible-light-driven hydrogen generation under the illumination of white LED in pure water or a mixture of DMF and H2O without additional photosensitizers and cocatalysts. Besides, the studies also showed that the catalytic activity changed constantly as well as the solvent ratio adjustment of DMF and H2O from 4:6 to 2:8. Additionally, the catalytic activity reached the best value (743 μmol g−1 h−1) when the solvent ratio was 4:6. The heterogeneous nature and recyclability of the MOF catalyst, as well as several factors that affect the catalytic activity, were investigated and described in detail. Moreover, the photocatalytic mechanism for the hydrogen generation of 1 was also proposed based on the fluorescence spectra and UV-vis absorption.

Control of adhesion and desorption behavior of silica particles on InGaAs surfaces by addition of hexadecyltrimethylammonium bromide in ammonium hydroxide–hydrogen peroxide mixture solution

The surface properties of InGaAs, such as zeta potential, surface energy components, acid–base energy constant, and Hamaker constant and its interaction force with silica particles, have not yet been elucidated. In this study, the adhesion of silica particles on an InGaAs surface in a 1/1/100 ammonium hydroxide (NH4OH)–hydrogen peroxide (H2O2)–H2O mixture (APM) solution was investigated. In particular, the effect of the addition of cationic surfactants and the concentration of hexadecyltrimethylammonium bromide (CTAB) on the particle adhesion/desorption was examined. To understand the adhesion behavior of silica particles on the InGaAs surface, the Lifshitz–van der Waals energy, acid–base interaction energy, and electrostatic energy between the silica particles and the InGaAs surface were estimated. It was found that the behavior of the energy barrier was strongly related to the number of silica particles that were adhered to the InGaAs. The energy barrier was reduced in the APM solution with 10−4 M CTAB, facilitating the adhesion of silica particles. However, when the CTAB concentration increased to 10−2 M, the energy barrier was elevated, and the adhesion of silica particles was reduced. The adhesion and desorption behaviors of silica particles on the InGaAs surface can be explained by the change in the energy barrier between the particles and InGaAs.

RETRACTED ARTICLE: Modeling of nanomaterial transportation over a sheet with involving MHD effect

Current modeling is presented to simulate the impression of magnetic forces and radiation of cooling of sheet. The testing fluid is mixture of copper oxide and H2O and due to low fraction, homogeneous model was imposed. Terms of radiation and magnetic were involved in energy and momentum equations. After converting the partial equation to final forms, RK4 was implemented to find the solution. Outputs were illustrated in view of profiles. Impose of Lorentz force can decline the f and increase the θ. Such forces prevent the nanomaterial to migrate and temperature boundary layer augments. Value of f declines about 6.4% with augment of M. Impact of λ on profiles augments as η increases. θ reduces about 78.79% but f augments about 131.8% when η = 2. Rise of temperature was result of increasing Rd become more obvious as η augments and influence of n on θ is opposite of that of Rd. Cf rise about 199.2% with rise of M when λ = 0.1 and it reduces about 53.97% with augment of λ when M = 12. Thinner boundary layer appears with rise of λ which provide greater Nu. At M = 12, Nu augments about 49.37% with rise of λ. Inclusion of magnetic force makes Nu to reduce about 27.25% when λ = 0.1. Nu declines about 64.75% with augment of Rd owing to reduction of temperature gradient. As n augments, Nu rise about 206.37% in absence of magnetic field.

Indications for accurate and appropriate use of personal protective equipment for healthcare professionals. A systematic review.

The speed of the spread of coronavirus disease 2019 (COVID-19) has put enormous pressure on hospitals and other healthcare facilities. This, together with blockages in several countries, has hindered the availability and accessibility of the necessary personal protective equipment (PPE). To identify, systematically evaluate and summarize the available scientific evidence on the efficacy, safety, safe use and reuse of PPE for healthcare professionals, for preventing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Systematic review of studies analyzing products for disinfecting and enabling reuse of PPE for coronavirus within the evidence-based health program of a federal university in São Paulo (SP), Brazil. A systematic search of the relevant literature was conducted in the PubMed, EMBASE, Cochrane Library, CINAHL, SCOPUS, Web of Science and LILACS databases, for articles published up to November 30, 2020. Ten studies were selected. These analyzed the use of N95, surgical and cotton masks, face shields, flexible enclosures with plastic covers or polycarbonate intubation boxes and plastic curtains; and also PPE disinfection using several substances. Combined use of a face shield with a N95 mask proved to be superior to other associations for protecting healthcare workers. Some products are useful for disinfecting PPE, such as 70% ethanol, 0.1% sodium hypochlorite and a mixture of quaternary ammonium and H2O2, and hydrogen peroxide. Ultraviolet light and dry heat at 70 °C can be used to decontaminate N95 masks. DOI: 10.17605/OSF.IO/4V5FD at the OPENSCIENCE Framework.

Plasma dynamics, instabilities and OH generation in a pulsed atmospheric pressure plasma with liquid cathode: a diagnostic study

While plasma–liquid interactions have been an important focus in the plasma research community, the impact of the strong coupling between plasma and liquid on plasma properties and processes remains not fully understood. In this work, we report on the impact of the applied voltage, pulse width and liquid conductivity on the plasma morphology and the OH generation for a positive pulsed DC atmospheric pressure plasma jet with He–0.1% H2O mixture interacting with a liquid cathode. We adopted diagnostic techniques of fast imaging, 2D laser induced fluorescence of OH and Thomson scattering spectroscopy. We show that plasma instabilities and enhanced evaporation occur and have a significant impact on the OH generation. At elevated plasma energies, it is found that the plasma contracts due to a thermal instability through Ohmic heating and the contraction coincides with a depletion in the OH density in the core due to electron impact dissociation. For lower plasma energies, the instability is suppressed/delayed by the equivalent series resistor of the liquid electrode. An estimation of the energy flux from the plasma to the liquid shows that the energy flux of the ions released into the liquid by positive ion hydration is dominant, and significantly larger than the energy needed to evaporate sufficient amount of water to account for the measured H2O concentration increase near the plasma–liquid interface.

Links between elevated zinc levels, diet and muscle melanisation in sand flathead (Platycephalus bassensis) from polluted estuaries

Muscle melanisation in sand flathead is defined as the presence of abnormal black spots in the fish's flesh and the phenomenon has been associated with Zn pollution in the environment. In this study, Zn levels in the fish muscle and crabs were analysed to investigate the role of Zn in causing muscle melanisation and the fish's uptake of Zn via its diet, crabs. An improved technique for extracting melanised fish muscle from fillets with black spots was developed. It enabled Zn levels in melanised muscle to be more accurately determined when compared to previous study and showed Zn levels were 2.1–3.5 times higher in melanised regions of muscle than non-melanised regions of muscle from fish with melanisation and fish unaffected by melanisation. This indicated elevated levels of Zn were localised in the melanised muscle. Muscle melanisation was potentially caused by Zn ions binding to the active site of tyrosinase, an enzyme involved in melanin production, likely facilitated by the presence of higher Zn than Cu in the polluted estuaries. A digestion reagent mixture suitable for microwave assisted acid digestion and analysis of Zn in the whole crab was developed using a mixture of HNO3 and H2O2. Zn levels in the whole crab were 1.5 times higher in 50% of the crab species studied from a polluted estuary compared to the same species from an unpolluted estuary. As sand flathead primarily feed on crabs, the fish's diet was a likely source of elevated Zn for the fish. Overall, this study has described new techniques useful for the study of melanised fish and heavy metal levels in the whole crab. The findings from this study also provided insights that will inform and guide the direction of future research on muscle melanisation in sand flathead.

NMR and MD Analysis of the Bonding Interaction of Vancomycin with Muramyl Pentapeptide.

The article describes an NMR spectroscopy study of interactions between vancomycin and a muramyl pentapeptide in two complexes: vancomycin and a native muramyl pentapeptide ended with D-alanine (MPP-D-Ala), and vancomycin and a modified muramyl pentapeptide ended with D-serine (MPP-D-Ser). The measurements were made in a 9:1 mixture of H2O and D2O. The obtained results confirmed the presence of hydrogen bonds previously described in the literature. At the same time, thanks to the pentapeptide model used, we were able to prove the presence of two more hydrogen bonds formed by the side chain amino group of L-lysine and oxygen atoms from the vancomycin carboxyl and amide groups. This type of interaction has not been described before. The existence of these hydrogen bonds was confirmed by the 1H NMR and molecular modeling. The formation of these bonds incurs additional through-space interactions, visible in the NOESY spectrum, between the protons of the L-lysine amino group and a vancomycin-facing hydrogen atom in the benzylic position. The presence of such interactions was also confirmed by molecular dynamics trajectory analysis.

Synthesis, crystal structure and supramolecular self-assembly of tetraphenylethylene subunit appended isoindigo derivatives

In this work, we design and synthesis donor-acceptor-donor based two new chromophores containing isoindigo (IN) as an acceptor core functionalised with two donor tetraphenylethylene (TPE) on the periphery one without thiophene spacer (Coded as: TPE-IN1) another derivative with thiophene as a spacer (Coded as: TPE-IN12. For the synthesis of both the derivatives Suzuki cross-coupling reaction was employed. Fluorescence emission spectral proeprties of TPE-IN1 and TPE-IN2 was investigated in mixture of chloroform (CHCl3):methylcyclohexane (MCH) and tetrahydrofuran (THF):water (H2O). The results shows an aggregation-caused quenching (ACQ) effect, which may be due to energy/electron transfer from TPE to IN core, as TPE is typically aggregation induced emission (AIE)-active chromophore. The self-assembled/aggregated structures in solution was characterized by means of fluorescence lifetime and dynamic light scattering (DLS) measurement. The crystalline morphology on the silicon wafer was investigated by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. Furthermore, our study of supramolecular self-assembly of TPE-IN1 and TPE-IN2 in THF:H2O (10:90%) and CHCl3:MCH (10:90%) solvent mixes shows various superstructures. Typically, TPE-IN1 displayed interesting hexagonal rod like morphology in THF:H2O mixture, where as TPE-IN2 showed self-assembled crystalline fibrous morphological micro and nanostructures via the solvophobic effect.
