Authors: Li Jiachen , Yang Sigang , Chen Hongwei , Wang Xingjun , Chen Minghua , Zou Weiwen
Published: April 2022

Microwave photonic receivers are a promising candidate in breaking the bandwidth limitation of traditional radio-frequency (RF) receivers. To further balance the performance superiority with the requirements regarding size, weight, and power consumption (SWaP), the implementation of integrated microwave photonic microsystems has been considered an upgrade path. However, up to now, to the best of our knowledge, chip-scale fully integrated microwave photonic receivers have not been reported due to the limitation of material platforms. In this paper, we report a fully integrated hybrid microwave photonic receiver (FIH-MWPR) obtained by comprising the indium phosphide (InP) laser chip and the monolithic silicon-on-insulator (SOI) photonic circuit into the same substrate based on the low-coupling-loss micro-optics method. Benefiting from the integration of all optoelectronic components, the packaged FIH-MWPR exhibits a compact volume of

and low power consumption of 1.2 W. The FIH-MWPR supports a wide operation bandwidth from 2 to 18 GHz. Furthermore, its RF-link performance to down-convert the RF signals to the intermediate frequency is experimentally characterized by measuring the link gain, the noise figure, and the spurious-free dynamic range metrics across the whole operation frequency band. Moreover, we have utilized it as a de-chirp receiver to process the broadband linear frequency-modulated (LFM) radar echo signals at different frequency bands (S-, C-, X-, and Ku-bands) and successfully demonstrated its high-resolution-ranging capability. To the best of our knowledge, this is the first realization of a chip-scale broadband fully integrated microwave photonic receiver, which is expected to be an important step in demonstrating the feasibility of all-integrated microwave photonic microsystems oriented to miniaturized application scenarios.

Authors: Xiang Chao , Jin Warren , Bowers John E.
Published: April 2022

The use of silicon nitride in integrated photonics has rapidly progressed in recent decades. Ultra-low-loss waveguides based on silicon nitride are a favorable platform for the research of nonlinear and microwave photonics and their application to a wide variety of fields, including precision metrology, communications, sensing, imaging, navigation, computation, and quantum physics. In recent years, the integration of Si and III-V materials has enabled new large-scale, advanced silicon nitride-based photonic integrated circuits with versatile functionality. In this perspective article, we review current trends and the state-of-the-art in silicon nitride-based photonic devices and circuits. We highlight the hybrid and heterogeneous integration of III-V with silicon nitride for electrically pumped soliton microcomb generation and ultra-low-noise lasers with fundamental linewidths in the tens of mHz range. We also discuss several ultimate limits and challenges of silicon nitride-based photonic device performance and provide routes and prospects for future development.
High-axial-resolution optical stimulation of neurons in vivo via two-photon optogenetics with speckle-free beaded-ring patterns
Authors: Jin Cheng , Liu Chi , Kong Lingjie
Published: April 2022

Two-photon optogenetics has become an indispensable technology in neuroscience, due to its capability in precise and specific manipulation of neural activities. A scanless holographic approach is generally adopted to meet the requirement of stimulating neural ensembles simultaneously. However, the commonly used disk patterns fail in achieving single-neuron resolution, especially in axial dimension, and their inherent speckles decrease stimulation efficiency. Here, we propose a novel speckle-free, beaded-ring pattern for high-axial-resolution optical stimulation of neurons in vivo. Using a dye pool and a fluorescent thin film as samples, we verify that, compared to those with disk patterns, higher axial resolution and better localization ability can be achieved with beaded-ring patterns. Furthermore, we perform two-photon based all-optical physiology with neurons in mouse S1 cortex in vivo, and demonstrate that the axial resolution obtained by beaded-ring patterns can be improved by 24% when stimulating multiple neurons, compared to that of disk patterns.

Published: April 2022

The purpose of this research was to investigate the key factors that influence behavioral intention to adopt MOOCs. The study was conducted in three countries namely, Poland, Thailand, and Pakistan. The study was considered significant considering the advancements in technology that have had an unprecedented impact on education, and the need to conduct learning online due to the COVID-19 to pandemics. The research adopted the Unified Theory of Acceptance and Use of Technology (UTAUT2) and extended it by including other variables including culture, social distancing, and absorptive capacity. The study was conducted using the quantitative methodology, where the data was collected using a structured questionnaire. The data was collected from a sample from each of the three countries, and sample sizes were 455, 490, and 513 for Poland, Thailand, and Pakistan respectively. The data were analyzed using Structural Equation Modeling (SEM) and multi-group SEM analysis. The results of the study indicated that effort expectancy and culture significantly and positively influenced behavioral intention to use MOOCs in all three countries. As well, absorptive capacity is mediated significantly by performance expectancy and effort expectancy. Facilitating conditions have a significant influence on MOOCs in both Thailand and Pakistan. Social influence has a significant influence on behavioral intention to use MOOCs in Thailand, hedonic motivation and price value have a significant influence on behavioral intention to use MOOCs in Poland, and the habit has a significant factor in Pakistan. The keys aspects influencing behavioral intention to Use MOOCs were different in Poland, Thailand, and Pakistan, in various factors which are performance expectancy, social distancing, price value, facilitating conditions, and social influence. The research recommended that it is important to evaluate the situation and prevailing conditions of the concerned country, before implementing the MOOCs and the associated online learning practices.

Authors: Mousa Doaa , Zayed Nourhan , Yassine Inas A.
Published: April 2022

Alzheimer’s disease (AD) affects the quality of life as it causes; memory loss, difficulty in thinking, learning, and performing familiar tasks. Resting-state functional magnetic resonance imaging (rs-fMRI) has been widely used to investigate and analyze different brain regions for AD identification. This study investigates the effectiveness of using correlated transfer function (CorrTF) as a new biomarker to extract the essential features from rs-fMRI, along with support vector machine (SVM) ordered hierarchically, in order to distinguish between the different AD stages. Additionally, we explored the regions, showing significant changes based on the CorrTF extracted features’ strength among different AD stages. First, the process was initialized by applying the preprocessing on rs-fMRI data samples to reduce noise and retain the essential information. Then, the automated anatomical labeling (AAL) atlas was employed to divide the brain into 116 regions, where the intensity time series was calculated, and the CorrTF features were extracted for each region. The proposed framework employed the SVM classifier in two different methodologies, hierarchical and flat multi-classification schemes, to differentiate between the different AD stages for early detection purposes. The ADNI rs-fMRI dataset, employed in this study, consists of 167, 102, 129, and 114 normal, early, late mild cognitive impairment (MCI), and AD subjects, respectively. The proposed schemes achieved an average accuracy of 98.2% and 95.5% for hierarchical and flat multi-classification tasks, respectively, calculated using ten folds cross-validation. Therefore, CorrTF is considered a promising biomarker for AD early-stage identification. Moreover, the significant changes in the strengths of CorrTF connections among the different AD stages can help us identify and explore the affected brain regions and their latent associations during the progression of AD.

Published: April 2022

Background

Non-alcoholic fatty liver disease (NAFLD) is associated with an increased risk of cardiovascular events. HDL exerts various protective functions on the cardiovascular system including anti-inflammatory activity by suppressing adhesion molecules expression in inflammation-induced endothelial cells. This study was designed to search if the anti-inflammatory capacity of apolipoprotein B-depleted plasma (apoB-depleted plasma) is altered in NAFLD patients.

Methods

A total of 83 subjects including 42 NAFLD and 41 control subjects were included in this cross-sectional study. Anti-inflammatory function of HDL was determined as the ability of apoB-depleted plasma to inhibit tumor necrosis factor-α (TNF-α)-induced expression of adhesion molecules in human umbilical vein endothelial cells (HUVECs).

Results

Incubation of inflammation-stimulated HUVECs with the NAFLD patients’ apo-B depleted plasma led to higher levels of expression of adhesion molecules compared to the control subjects’ plasma samples, reflecting an impaired anti-inflammatory capacity of apoB-depleted plasma in the NAFLD patients. Impaired anti-inflammatory capacity of apoB-depleted plasma was correlated with fatty liver and obesity indices. After adjustment with obesity indices, the association of anti-inflammatory capacity of apoB-depleted plasma with NAFLD remained significant.

Conclusion

Impaired anti-inflammatory activity of apoB-depleted plasma was independently associated with NAFLD.

Pulmonary vein isolation has become a cornerstone treatment for catheter ablation of atrial fibrillation (AF). Recent reports show that additional ablation targeting low-voltage zones reduces AF recurrence. However, the pre-procedural predictors of low-voltage zones remain elusive. We retrospectively enrolled 359 patients (mean age 63.7 ± 10.8 years; 73 females; and 149 had persistent atrial fibrillation) who underwent catheter ablation for AF and left atrial (LA) voltage mapping during sinus rhythm or atrial pacing. Low-voltage zones were defined as area of > 5 cm2 with a bipolar electrogram amplitude of < 0.50 mV. Overall, 51 (14.2%) patients had low-voltage zones. Patients with low-voltage zones were older (67.9 ± 9.9 vs. 63.0 ± 10.8 years; P = 0.003), predominantly female (33.3% vs. 18.2%; P = 0.013), had higher prevalence of dilated cardiomyopathy (DCM) (11.8% vs. 1.6%; P = 0.002) and hypertrophic cardiomyopathy (HCM) (9.8% vs. 2.6%; P = 0.025), and had larger LA volumes (153.6 ± 46.4 vs. 117.7 ± 67.8 mL; P < 0.001) than those without low-voltage zones. Multivariate logistic regression analysis revealed that age (OR 1.060; 95% CI 1.022–1.101, P = 0.002), female sex (OR 2.978; 95% CI 1.340–6.615, P = 0.007), DCM (OR 8.341; 95% CI 1.381–50.372, P = 0.021), HCM (OR 5.044; 95% CI 1.314–19.363, P = 0.018), persistent AF (OR 4.188; 95% CI 1.928–9.100, P < 0.001), and larger LA volume (OR 3.215; 95% CI 1.378–7.502, P = 0.007) were independently associated with the presence of low-voltage zones. Patient age, female sex, DCM, HCM, persistent AF and larger LA volume may predict the presence of low-voltage zones and could be useful in selecting the appropriate ablation strategy for AF.
Feeding of faba beans (Vicia faba L.) enhances the growth performance of lambs
Authors: Al Shabuol Nawras L. , Obeidat Belal S.
Published: April 2022

Background and Aim: The high price of conventional diet ingredients led livestock producers to search for alternative feed sources such as faba beans (Vicia faba L.; FB). This study aimed to evaluate the effect of feeding FB on the growth performance of lambs.

Materials and Methods: A total of 24 male lambs were distributed randomly into two groups and fed a control diet (CON; n=12) and 200 g/kg FB (FB200; n=12) dietary dry matter (DM). The study lasted for 70 days. The first 7 days were used for acclimatization, followed by 63 days of data collection (i.e., nutrient intake and digestibility and growth performance). A complete randomized design was used for the statistical analysis.

Results: The average initial body weight (BW) (20.54±0.798 kg) was similar between the diet treatment groups. Lambs fed the FB200 diet demonstrated higher (p≤0.008) nutrient intake than lambs fed the CON diet. The FB200 diet tended to improve the digestibility of DM, crude protein, and acid detergent fiber more than the CON diet (p≤0.072). Neutral detergent fiber and ether extract digestibility were higher (p<0.05) in lambs fed the FB200 diet than those fed the CON diet. Next, nitrogen retention increased (p<0.05) in lambs fed the FB200 diet compared with the CON diet. Final BW did not differ (p=0.221) between the two groups. However, the average daily gain was higher (p=0.028) in lambs fed the FB200 diet than in lambs fed the CON diet. Furthermore, the cost of gain decreased more (p=0.04) with the FB200 diet than with the CON diet.

Conclusion: The results obtained in this study demonstrate the feasibility of using FB in feeding growing lambs, as it was shown to improve growth performance and reduce the cost of diet and gain.

Pop, Politik und Populismus als Massenkultur
Authors: Schiller Melanie
Published: April 2022

Melanie Schiller widmet sich in diesem Beitrag der Frage nach den wechselseitigen Beziehungen von populärer Kultur, Massenkultur und Populismus. Hierbei legt Schiller zunächst einige historische Parallelen dar und bezieht sich dabei unter anderem auf Walter Benjamin. Schiller zeigt auf, inwiefern zeitgenössischer Populismus nicht als Gegenentwurf zum Pop missverstanden werden sollte (und vice versa), sondern dass ein Verständnis von Populismus als Popkultur indes neue Erkenntnisse über seine Popularität zulassen. Während Benjamin diesen Prozess mit Bezug auf den Faschismus als die Ästhetisierung der Politik beschrieben hat, argumentiert Schiller, dass wir im heutigen Kontext von der Popifzierung der Politik durch Populismus sprechen können.
Das Paradigma Kollektiv
Authors: Hansen Klaus P.
Published: April 2022

Trotz seiner Einzigartigkeit gehört jedes Individuum unzähligen Kollektiven an, die sich aus der jeweiligen Dynamik von Gemeinsamkeit und Differenz entwickeln. Von dieser Prämisse ausgehend, präsentiert Klaus P. Hansen ein kollektivwissenschaftliches Paradigma, welches das Grundmodell Kollektiv-im-Kollektiv in seine Möglichkeiten und deren Bedingungen auseinanderfaltet. Um diese Varianten zu erfassen, werden die Begriffe »Multi-, Prä-, Pan- und Polykollektivität« eingeführt. Diese Begriffe eröffnen eine kleinteilige Sicht auf Sozialität, die ohne die Vereinheitlichungen Gesellschaft und/oder Kultur auskommt.
Geister der Kindheit
Authors: Funk Leberecht
Published: April 2022

Die Sozialisation von Emotionen ist bislang vor allem in euroamerikanischen Mittelschichten untersucht worden. Leberecht Funk analysiert in seiner sozial- und kulturanthropologischen Studie emotionale Sozialisationspraktiken bei den Tao, die auf Lanyu, einer zu Taiwan gehörenden Insel, leben. Lokalen Vorstellungen zufolge bedrohen Geister die Seelen von Kindern. Als Teil ihrer Erziehung und zu ihrem Schutz werden die Kinder einer ambivalent erscheinenden Form der Abhärtung unterzogen, die eine spezifische moralische Angst- und Scham-Disposition in ihnen hervorruft, die sie im späteren Entwicklungsverlauf überwinden müssen. Die Studie zeigt, dass die ontogenetische Entwicklung von Emotionen eine größere Plastizität aufweist als bislang in der Entwicklungspsychologie angenommen.

Automatic control system of the reactive power factor of the power supply system of the industrial enterprise
Authors: Kotenev Viktor I. , Kotenev Alexander V. , Stulov Alexander D.
Published: April 2022

Considered is the control of the reactive power factor of the power supply system of an industrial enterprise, which includes: electrical receivers with asynchronous load; workshop transformer substations with and without regulated capacitor units, as well as the main step-down substation with synchronous motors powered from it. It is proposed to consider electrical receivers with capacitor units and a transformer substation as an object of reactive power factor control, on the basis of which the corresponding automatic control system (ACS) is built. An ACS with an algorithm formed as a function of active and reactive power of electrical receivers is considered. The ACS was developed by the reactive power factor of the power supply system of the entire enterprise with shop combined loads. A method is given for calculating the capacity of capacitor units of shop substations. The use of this control system will allow meeting the regulatory requirements for ensuring the limiting values of the reactive power coefficients and thereby reducing losses during the transportation of electricity and increasing the throughput of the electrical network.
A Conceptual Framework about Employees’ Proactive Behavior and Supervisor’s Favorable Evaluation: Moderating Effects of Dissimilarity in Supervisors’ Cultural Dimensions
Authors: Rakthin Sirisuhk , Punnakitikashem Prattana , Otakanon Burim , Khin Khin Oo Nay Chi
Published: April 2022

This study aims to develop a theoretical model of how supervisor’s cultural differences moderate the relationship between proactive behavior of employees and the supervisor’s favorable evaluations. We first review the literature and define the constructs. Then, we describe how the relationship between proactive behavior of an employee and the supervisor’s favorable assessment level could be moderated by the differences between the models of independent or individualistic culture vs. interdependent or collectivistic culture and the cultural tightness-looseness of the supervisor. The conceptual framework and theoretical models of this relationship and moderating effects are proposed. The theoretical model of this study contributes to the organizational and strategic management literature by proposing the moderating effects of supervisor’s cultural differences in assessing different aspects of employee’s proactive behavior.

Indeksy demokracji i stan zaawansowania ich rozwoju dla pomiaru jakości demokracji na poziomie lokalnym
Authors: Andrzejewski Szymon
Published: April 2022

Jak mierzyć demokrację? Jak ocenić, czy jeden ustrój demokratyczny jest bardziej demokratyczny od innego i na jakiej podstawie to stwierdzić? Pomiary jakości demokracji na poziomie państw istnieją już od 1946 roku, a na ich podstawie powstawały indeksy demokracji jak np. Freedom House, Polity IV, czy też Varieties of Democracy. Poza poziomem państw jest zdecydowanie mniej narzędzi tego typu, a istniejące – jak np. Local Autonomy Index – nie dotyczą bezpośrednio miast. Poniższy artykuł stawia tezę, że indeks demokracji na poziomie lokalnym jest potrzebny dla rzetelnej analizy jakości demokracji w polskich gminach i miastach. Przeanalizowano w nim dotychczasowe doświadczenia w mierzeniu jakości demokracji na poziomie miast, kierując się podejściem w duchu instytucjonalnym. Następnie omówiono przykłady lokalnych indeksów demokratycznych np. The Civic Index z USA, i najnowszą propozycję indeksu demokratycznego dla miast portugalskich. W zakończeniu zaproponowano zarys metodyki do mierzenia demokracji na poziomie miast w Polsce.

Published: April 2022

Aging is associated with attenuated sweat gland function, which has been suggested to occur in a peripheral‐to‐central manner. However, evidence supporting this hypothesis remains equivocal. We revisited this hypothesis by evaluating the sweat rate across the limbs and trunk in young and older men during whole‐body, passive heating. A water‐perfused suit was used to raise and clamp esophageal temperature at 0.6°C (low‐heat strain) and 1.2°C (moderate‐heat strain) above baseline in 14 young (24 (SD 5) years) and 15 older (69 (4) years) men. Sweat rate was measured at multiple sites on the trunk (chest, abdomen) and limbs (biceps, forearm, quadriceps, calf) using ventilated capsules (3.8 cm2). Sweat rates, expressed as the average of 5 min of stable sweating at low‐ and moderate‐heat strain, were compared between groups (young, older) and regions (trunk, limbs) within each level of heat strain using a linear mixed‐effects model with nested intercepts (sites nested within region nested within participant). At low‐heat strain, the age‐related reduction in sweat rate (older‐young values) was greater at the trunk (0.65 mg/cm2/min [95% CI 0.44, 0.86]) compared to the limbs (0.42 mg/cm2/min [0.22, 0.62]; interaction:p = 0.010). At moderate‐heat strain, sweat rate was lower in older compared to young (main effect:p = 0.025), albeit that reduction did not differ between regions (interaction:p = 0.888). We conclude that, contrary to previous suggestions, the age‐related decline in sweat rate was greater at the trunk compared to the limbs at low‐heat strain, with no evidence of regional variation in that age‐related decline at moderate‐heat strain.
Reception of the Lord’s Prayer in Pentecostal-Charismatic Christianity in Ghana
Authors: Wandusim Michael F.
Published: April 2022

The liturgical reception of the Lord’s Prayer (Matt 6:9–13 par. Luke 11:2 b–4) is well-attested and still evident in Catholic, Protestant and Orthodox circles. For instance, in reformed worship it is usual to hear varied versions of the statement: “And now as our saviour Christ has taught us, we humbly pray: ‘Our Father who art in heaven (…)’.” It is striking, however, that such a liturgical use of the text is scarce in Pentecostal-Charismatic Christian worship. Such is the case in Ghana, where Pentecostal-Charismatic Christianity forms the largest and most popular stream of the tradition. It only takes a visit to a Ghanaian Pentecostal-Charismatic church during a worship session to ascertain this fact. This article investigates this liturgical phenomenon in Pentecostal-Charismatic worship by analyzing a selection of popular literature written on the text of the Lord’s Prayer and through personal interviews with some of the leaders of Pentecostal-Charismatic churches. Before engaging in reception analysis, a brief exegetical study of the text is undertaken. The article concludes that the Lord’s Prayer does not appear in Pentecostal-Charismatic liturgy because it does not conform with the Pentecostal-Charismatic understanding of prayer. Instead it is conceived of as a pattern or model and hence chiefly employed as a means of instruction on effective prayer rather than for recitation each Sunday, as manifest in Protestant, Catholic, and Orthodox circles.

Wood is the most expensive fraction in the pulp production costs. Therefore, strategies for increasing wood quality such as faster growth, higher wood basic density and lower lignin content are drivers to pulp mills. The cultivation site as well as the eucalypt clones influence the wood quality, which, in turn, affects the pulp production performance. Thus, this work aims to evaluate the effect of the site on the wood quality for the pulp production. Three eucalypt clones from five different sites in Brazil were used in this study. These samples were selected aiming to represent a gradient of environmental stress. It was possible to observe a reduction in the content of extractives and lignin and an increase in the content of glucans in the sites with less environmental stress, reflecting in the production of pulp with less effective alkali demanded (reduction of 13.5 %) and an increase of 10.5 % in the kraft pulp screened yield. MAIP values of 22.7 ton/ha/year were obtained in the sites with less environmental stress, presenting a lower specific wood consumption. Through the production indicators, it was observed that the C1 clone is more adaptable to the regions of greater environmental stress than the other clones analyzed.
Gut dysbiosis and homocysteine: a couple for boosting neurotoxicity in Huntington disease

Published: April 2022

Huntington’s disease (HD), a neurodegenerative disorder caused by an expansion of the huntingtin triplet (Htt), is clinically characterized by cognitive and neuropsychiatric alterations. Although these alterations appear to be related to mutant Htt (mHtt)-induced neurotoxicity, several other factors are involved. The gut microbiota is a known modulator of brain-gut communication and when altered (dysbiosis), several complaints can be developed including gastrointestinal dysfunction which may have a negative impact on cognition, behavior, and other mental functions in HD through several mechanisms, including increased levels of lipopolysaccharide, proinflammatory cytokines and immune cell response, as well as alterations in Ca2+ signaling, resulting in both increased intestinal and blood-brain barrier (BBB) permeability. Recently, the presence of dysbiosis has been described in both transgenic mouse models and HD patients. A bidirectional influence between host brain tissues and the gut microbiota has been observed. On the one hand, the host diet influences the composition and function of microbiota; and on the other hand, microbiota products can affect BBB permeability, synaptogenesis, and the regulation of neurotransmitters and neurotrophic factors, which has a direct effect on host metabolism and brain function. This review summarizes the available evidence on the pathogenic synergism of dysbiosis and homocysteine, and their role in the transgression of BBB integrity and their potential neurotoxicity of HD.

The 1:1 co-crystals formed between 2-amino-5-chloropyridine/2-amino-5-bromopyridine and isomeric n-methyl-benzoic acids [n = 2, 3 and 4] are described. The co-crystals with the n = 2 co-former are isostructural. The co-formers are linked by intermolecular hydrogen bonds involving amino-N–H⋯O(carbonyl) and hydroxyl-O–H⋯N(pyridine). Additional and comparable amino-N–H⋯O(carbonyl) hydrogen bonds were evident in all co-crystals and play an important role in stabilising the molecular packing. The intermolecular interactions were also analysed through the calculated Hirshfeld surfaces. The charge transfer occurring between the calculated HOMO-LUMO states suggests electron mobility within the co-crystals owing to the aforementioned hydrogen bonding.

The computational solution is considered an effective tool for the analysis and a good understanding of the complex microstructural development that occurs during friction surfacing. In this article, ABACUS software was used to create a 3D-FE model of friction surfaced layering of AA 6063 aluminium on EN8 carbon steel, and the heat and strain rate collected throughout the operation were utilised for a computational investigation of microstructural recrystallization and grain development. The Multi-phase Field model (MFM) and constructive material model (CMM) were used for the prediction of the grain development during the process. A decrease in the incubation period from 0.839 sec to 0.578 sec was seen before recrystallization, after a temperature rises from 100°C to 300°C for substrate preheating. Validation of the reliability model obtained from the computational study was done using the image received from electron backscattered diffraction (EBSD) for grain size development and distribution. An appropriate assessment has been made between computational and experimental images which shows the maximum error of less than 10%. The development of grain structure during recrystallization was impacted extensively for increasing the coating strength, which was seen as inversely proportional to the average coating's grain diameter.

An organic third-order nonlinear optical single crystal of 8-hydroxyquinolinium trichloroacetate (8HQTC) has been broughten about by proton transfer reaction established by slow evaporation method. Single crystal X-ray diffraction analysis profoundly revealed the crystal structure of 8HQTC in monoclinic system with the space group of C2/c. 8-hydroxyquinolinium (8HQ+) cations are linked to trichloroacetate (TCA- ) anions forming an ion pairs through these hydrogen atoms H6 of N1 and H5 of O1 in the form of N1__H6···O3 and O1__H5···O3 intermolecular hydrogen bonds in the unit cell that produce ring R4 2 (14) motif. The vibrational (FTIR and FTRaman)andopticaltransmittance(UV-Vis-NIR) spectral analysis were efficaciously carried out for 8HQTC crystal. TG-DTA analysis of grown material revealed the thermal stability upto 140 °C. The Frequency and temperature dependent dielectric constant and dielectric loss of the grown crystal was analysed. The nonlinear optical properties such as nonlinear refractive index (n2=8.36 x 10-12 m 2 /W) , nonlinear absorption coefficient (β=5.69 x 10-6 ) and third order susceptibility (χ(3) = 4.51 x 10-5 esu) values have been calculated for grown 8HQTC crystal using Z-scan measurements. The correlation between molecular structure of 8HQTC and its molecular perspectives has been accomplished by density functional theory (DFT) method.
