Improving Hole-Conductor-Free Fully Printable Mesoscopic Perovskite Solar Cells’ Performance with Enhanced Open-Circuit Voltage via the Octyltrimethylammonium Chloride Additive

Hole-conductor-free fully printable mesoscopic perovskite solar cells (MPSCs) based on mp-TiO2/mp-ZrO2/carbon triple mesoscopic layers are competitive candidates among various rapidly developed PSCs for future photovoltaic applications due to the characteristics of low-cost, easy upscaling, and superior stability. However, the open-circuit voltage (V-OC) loss in printable MPSCs is relatively large compared to that in conventional PSCs, deteriorating the power conversion efficiency (PCE). Herein, the V-OC loss is reduced by the octyltrimethylammonium chloride (OTAC) additive. OTAC is found to upshift the Fermi level of TiO2 and passivate trap states in bulk MAPbI(3) perovskite, thus optimizing the energy-level alignment of the TiO2/perovskite heterojunction and suppressing nonradiative recombination in devices. As a result, MPSCs deliver the highest PCE of 16.53% with an improved V-OC of 1007 mV. The work demonstrates a facile strategy to reduce the V-OC loss in printable MPSCs by simultaneously optimizing the energy-level alignment and suppressing nonradiative recombination.

Thin-film nanocomposite membranes containing tannic acid-Fe3+ modified MoS2 nanosheets with enhanced nanofiltration performance

The development of thin-film nanocomposite (TFN) membranes for water treatment is of immense scientific interest. In this work, MoS2 nanosheets modified with tannic acid (TA)-Fe3+ coordination complexes were embedded within the polyamide (PA) layer to construct TFN nanofiltration (NF) membranes. The incorporation of modified MoS2 nanosheets into the PA matrix facilitates the formation of a bumpy surface with the appearance of scattered protuberances. Besides, the introduced covalent bonding between phenol groups and unreacted acid chloride groups during interfacial polymerization contributes to an enhanced crosslinking degree of the PA layer, simultaneously avoiding the formation of non-selective interfacial voids. The optimal TFN NF membrane with the addition of 0.01 wt% modified MoS2 nanosheets demonstrates 1.6-fold water permeance of the TFC membrane, along with increased salt rejection. The improved permeance of the TFN membrane is mainly due to the crumpled surface architecture with high roughness, which increases the permeable area for water transport. Overall, our study suggests that the employment of TA-MoS2 nanosheets for the construction of TFN membranes can be a promising method to develop high-performance NF membranes.

Development of a micro/nano composite sufper-hydrophobic silicon surface with nail-shaped texture/dual self-assembly monolayers and its wetting behavior

Micro-electromechanical systems often fail due to adhesion or wear, and preparing a stable super-hydrophobic surface is an effective approach to solve this problem. In this paper, the microscale square texture and nailshaped texture were designed and fabricated, and the nanoscale N-[3-(Trimethoxysilyl) propyl] ethylenediamine- Lauroyl chloride (DA-LA) dual self-assembly monolayers (SAMs) was developed to form a micro/nano composite structure. Meanwhile, micro/nanoscale surface morphology, chemical composition and surface free energy were characterized or calculated. Further, wettability and stability experiments were carried out. The results showed that the micro/nano composite structure achieves super-hydrophobicity and enhanced stability, and the maximum contact angle reaches 170.35 degrees. The nail-DA-LA surface with a 54.7 degrees overhang angle and rough sidewalls exhibited prominent super-hydrophobic stability, and the tribological experiments showed that the adhesion/friction reduced by 46.71% and 52.26%.

Inter-population differences in salinity tolerance of adult wild Sacramento splittail: osmoregulatory and metabolic responses to salinity

The Sacramento splittail (Pogonichthys macrolepidotus) is composed of two genetically distinct populations endemic to the San Francisco Estuary (SFE). The allopatric upstream spawning habitat of the Central Valley (CV) population connects with the sympatric rearing grounds via relatively low salinity waters, whereas the San Pablo (SP) population must pass through the relatively high-salinity Upper SFE to reach its allopatric downstream spawning habitat. We hypothesize that if migration through SFE salinities to SP spawning grounds is more challenging for adult CV than SP splittail, then salinity tolerance, osmoregulatory capacity, and metabolic responses to salinity will differ between populations. Osmoregulatory disturbances, assessed by measuring plasma osmolality and ions, muscle moisture and Na+-K+-ATPase activity after 168 to 336 h at 11 parts per thousand salinity, showed evidence for a more robust osmoregulatory capacity in adult SP relative to CV splittail. While both resting and maximum metabolic rates were elevated in SP splittail in response to increased salinity, CV splittail metabolic rates were unaffected by salinity. Further, the calculated difference between resting and maximum metabolic values, aerobic scope, did not differ significantly between populations. Therefore, improved osmoregulation came at a metabolic cost for SP splittail but was not associated with negative impacts on scope for aerobic metabolism. These results suggest that SP splittail may be physiologically adjusted to allow for migration through higher-salinity waters. The trends in interpopulation variation in osmoregulatory and metabolic responses to salinity exposures support our hypothesis of greater salinity-related challenges to adult CV than SP splittail migration and are consistent with our previous findings for juvenile splittail populations, further supporting our recommendation of population-specific management.

Entropy generation analysis of triple diffusive flow past a horizontal plate in porous medium

The combined natural heat and mass transfer, the so-called thermosolutal convective problem, has become an attractive field of research in many diversified areas. In this paper, for the first time, entropy analysis has been carried out for triple diffusive flow. A comprehensive model is developed for the entropy generation due to fluid friction, porous medium, heat, and mass transfer across a finite temperature and concentration difference in the chemical potential of two salts. In this model, a new term showing the entropy generation due to the coupling of concentration gradients of both salts is included. Furthermore, we have introduced a new mass Bejan number for the salts concentrations. The selected salts include sodium chloride and sucrose, which are added in water with different concentrations. The concentrations of both salts are assumed to be higher at the surface. The previously established dimensionless governing equations with Boussinesq approximation and Darcy law were solved numerically. The resulting velocity, temperature, and concentration gradients are employed in the entropy generation model. The impacts of the pertinent parameters and related dimensionless numbers on the dimensionless entropy generation rate, irreversibility ratio and Bejan numbers are examined for both assisting and opposing flows. It has been found that entropy generation rates are higher for assisting flows than opposing flows. At the same time, it is possible to reduce the entropy generation rate with a rise of the Darcy and Lewis numbers while the mass Bejan number increases with Lewis number. (C) 2020 Elsevier Ltd.

Enhanced Separation of Neodymium and Dysprosium by Nonaqueous Solvent Extraction from a Polyethylene Glycol 200 Phase Using the Neutral Extractant Cyanex 923

Neodymium and dysprosium can be efficiently separated by solvent extraction, using the neutral extractant Cyanex 923, if the conventional aqueous feed phase is largely replaced by the green polar organic solvent polyethylene glycol 200 (PEG 200). While pure aqueous and pure PEG 200 solutions in the presence of LiCl or HCl were not able to separate the two rare earth elements, high separation factors were observed when extraction was performed from PEG 200 chloride solutions with addition of small amounts of water. This addition of water bridges the gap between traditional hydrometallurgy and novel solvometallurgy and overcomes the challenges faced in both methods. The effect of different variables was investigated: water content, chloride concentration, type of chloride salt, Cyanex 923 concentration, scrubbing agent. A Job plot revealed the extraction stoichiometry is DyCl3 center dot 4L, where L is Cyanex 923. The McCabe-Thiele diagram for dysprosium extraction showed that complete extraction of this metal can be achieved by a 3-stage counter-current solvent extraction process, leaving neodymium behind in the raffinate. Finally, a conceptual flow sheet for the separation of neodymium and dysprosium including extraction, scrubbing, stripping, and regeneration steps was presented. The nonaqueous solvent extraction process presented in this paper can contribute to efficient recycling of rare earths from end-of-life neodymium-iron-boron (NdFeB) magnets.

Evaluation of Anti-depressant and Anti-anxiety Activity of Methanol Extract of Stachys annua L. in Mice

Background and objectives: Development of new medicines with fewer side effects and more efficacy is needed for treatment of depressive and anxiety disorders. The present study was designed to investigate the antidepressant and anti-anxiety effects of Stachys annua L. methanol extract in mice. Methods: The extract was prepared by maceration method and the total phenolic and flavonoid contents were determined by Folin-Ciocalteu and aluminum chloride methods, respectively. Elevated plus-maze (EPM) and open field tests (OFT) were applied to evaluate the anti-anxiety and locomotor activity of animals treated with the intraperitoneal (i.p.) extract (12.5, 25, 50, and100 mg/kg), respectively. Antidepressant activity was evaluated by forced swim test (FST) and tail suspension test (TST). Results: The total phenolic content of the extract was 54.13 +/- 0.01 mg of gallic acid equivalents per gram of dry extract and total flavonoid content was 67.89 +/- 0.005 mg of quercetin as equivalents/ g of extract. Intraperitoneal administration of the extract (50 and 100 mg/kg) significantly increased the percentage of time spent and the percentage of arm entries into the open arms of EPM and decreased locomotor activity, compared with the vehicle control group. In addition, the immobility time of animals significantly decreased in both FST and TST with doses of 25, 50, and 100 mg/kg of the extract, compared with the vehicle control group. Conclusion: The extract of Stachys annua L. might be used as an adjunct therapy in clinical studies for the treatment of depressive and anxiety disorders. However, determination of active ingredients needs further evaluation.

alpha-SnF2: A UV Birefringent Material with Large Birefringence and Easy Crystal Growth

The simple binary fluoride alpha-SnF2 is shown to be an excellent birefringent material with outstanding birefringence, about 14 times that of MgF2. Furthermore, it exhibits a shorter UV cutoff edge and easy crystal growth at ambient temperature compared to YVO4 and TiO2. A novel theoretical calculation mode was established to analyze the stereochemical-activity lone-pair (SCALP) contribution to the birefringence (SCB) based on the SCALP ‘ s strength and arrangement, and it was found that the large birefringence of alpha-SnF2 mainly benefits from well-aligned [SnF5] polyhedra with a strong SCALP. The exploration of the alpha-SnF2 birefringent crystal points out the direction of the future search for excellent birefringent materials.

Urinary concentrations of phthalate metabolites in pregnant women living near Chapala Lake, Jalisco, Mexico

Phthalates are esters of phthalic acid used in a broad array of consumer products and food contact surfaces. Phthalates are known endocrine disruptors and oxidant stressors, and exposure has been associated with premature birth, asthma, obesity, insulin resistance and endometriosis. Though many industrializing countries are known to manufacture phthalates, few studies have examined exposure to phthalates in this context, let alone in rural communities where phthalate-containing products are widely used. We evaluated the presence of 16 phthalate metabolites in third trimester pregnant women in three rural communities near the largest lake in Mexico, Lake Chapala, by liquid chromatography coupled to tandem mass spectrometry in 90 urine samples. Phthalate metabolites were found in all samples, where the highest concentration was 1830 ng/mL in mono-ethyl phthalate (mEP), and it was present in 98.9% of all samples. These findings suggest the need for further research on the effect of endocrine disrupting chemicals in developing countries, and public health guidance on opportunities for prevention.

Design of recyclable, fast-responsive and high temperature shape memory semi-aromatic polyamide

Development of high temperature shape memory polymers with fast response time and recyclable performance is highly desired. In this study, a new semi-aromatic tri-amine (TRIA) containing thioether unit is prepared through the reaction of trifluoro-monomer and p-mercaptoaniline (p-MA). It is conducted to polymerize with 4,4′-thiodibenzoyl chloride (TDC) and different ratios of diamine (both of them contained flexible thioether group) to supply a series of slightly crosslinking semi-aromatic polyamide. It is found that the resultant polymers had excellent thermal properties (T-g, 237.9-245.8 degrees C, T-d, 430.9-436.5 degrees C) and mechanical properties (tensile strength, 74-100 MPa). Because of the introduction of the large amount of flexible thioether group, the resultant polyamides can be dissolved in some aprotic solvents, and can be processed with solution method to fabricate a series of fast-responsive shape memory film (SMF) with a responsive time of 6-8 s, recovery rate of 98-99.5% after 20 cycles. What’s more, the oxidized film can even lift a weight equal to about 2-3 times (vertical direction) and 5-8 times (horizontal direction) of its own weight. Interestingly, unlike other shape memory polymers, these SMF after multiple processes (after bending-recovery cycle at high temperature) can still be processed repeatedly with a solution route, which supplies a novel and recyclable candidate for excellent performance SMP. It is expected to be used in solar cell wingspan actuator to light the satellite weight.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6940-78-9, you can contact me at any time and look forward to more communication. Recommanded Product: 6940-78-9.
