Origin of Photoluminescence, Exciton Binding Energy, Exciton-Phonon interaction, and Urbach Energy in γ-CsPbI3 Nanoparticles.
Authors: Gau Daniel , Galain Isabel , Aguiar Ivana , Marotti Ricardo
Published: October 2022

Recently inorganic perovskites have had a deep impact in perovskites-based devices allowing the fabrication of high efficiency and high stability devices. To continue with the development of these technologies a detailed study of the optoelectronic properties of these materials is necessary since this is a fundamental tool for the design of new and more efficient devices. In the present work, the optical properties of γ-CsPbI3 nanoparticles are studied using temperature dependent spectroscopic techniques of transmittance and photoluminescence. The absorption spectrum shows a marked excitonic behavior especially at low temperatures. Analyzing this spectrum with the Elliot function the evolution with temperature of the bandgap and the exciton binding energy is studied. From the evolution of the shape of the excitonic peak, both in the absorption and photoluminescence, we determined the excitonic recombination nature of photoluminescence and exciton-phonon interaction energy. Once proven the excitonic nature of photoluminescence we prove that the Stokes Shift has its origin in excitonic thermalization. Finally, analyzing the low energy region of the absorption spectrum the Urbach energy was determined. The obtained values, which are very low for solution processed nanoparticles, indicates that the nanoparticles present excellent crystallinity and are suitable for the implementation of quantum electronic devices.
Band Inversion-Driven Warping and High Valley Degeneracy
Authors: Toriyama Michael , Snyder G. Jeffrey
Published: October 2022

Band inversion is a physical phenomenon which may cause warping of the bulk band structure in topological insulators, generating multiple electronic valleys for conducting carriers. However, the conditions under which band inversion induces warping are not well understood. Here, we derive two general conditions which must be satisfied for band warping to occur in topological insulators: (i) bands must be sufficiently inverted, and (ii) secondary bands must have opposite parity and be close in energy to the band edges. We chart the valley degeneracies that can emerge from band inversion in each of the 11 centrosymmetric point groups, demonstrating that an increase in the valley degeneracy between 2-fold and 48-fold is possible from band inversion. The generalized rules offer a novel band engineering approach by capitalizing on the unique electronic structures of topological insulators.
Copper-Catalyzed Enantioselective Synthesis of α-Aminoboronic Acid Derivatives
Authors: Zuccarello Giuseppe , Batiste Suzanne M. , Cho Hyungdo , Fu Gregory C.
Published: October 2022

Optically active α-aminoboronic acids, find widespread application in medicinal chemistry. . Herein, we present a straightforward synthetic strategy based on the enantioselective cross-coupling of readily available racemic α-chloro boronates with carbamates using an earth-abundant copper catalyst with a commercial chiral diamine and a diaryl phosphine as the ligands. These reaction conditions originated from a mechanistic study of a photoinduced system. Mechanistic investigations support that product formation occurs via kinetic resolution of the racemic α-chloro boronate. Moreover, the diaryl phosphine is alkylated by the electrophile under the reaction conditions forming α-phosphino boronates that act as the active ligand during catalysis.
Mechanical Force Enables an Anomalous Dual Ring-Opening Re-action of Naphthodipyran
Authors: McFadden Molly E. , Osler Skylar K. , Sun Yan , Robb Maxwell J.
Published: October 2022

Multimodal mechanophores that exhibit complex mechanochromic behavior beyond the typical binary response are capable of distinguishing between multiple stress states through discrete changes in color. Naphthodipyran photoswitches contain two pyran rings fused to a central naphthalene core and represent a potentially promising framework for multimodal reactivity. However, the concurrent ring opening of both pyran moieties has previously proven inaccessible via photochemical activation. Here, we demonstrate that mechanical force supplied to naphthodipyran through covalently bound polymer chains generates the elusive dual ring-opened dimerocyanine product with unique near-infrared absorption properties. Trapping with boron trifluoride renders the merocyanine dyes thermally persistent and reveals unusual sequential ring-opening behavior that departs from the reactivity of previously studied mechanophores under the high strain rates imposed by ultrasound-induced solvodynamic chain extension.

Orexins are a family of neuropeptides that regulate various physiological events such as sleep/wakefulness as well as emotional and feeding behavior, and that act on two G-protein-coupled receptors, i.e., the orexin 1 (OX1R) and orexin 2 receptors (OX2R). Since the discovery that dysfunction of the orexin/OX2R system causes the sleep disorder narcolepsy, several OX2R-selective and OX1/2R dual agonists have been disclosed. However, an OX1R-selective agonist has not yet been reported, despite the importance of the biological function of OX1R. Herein, we report the discovery of a potent OX1R-selective agonist, (R,E)-3-(4-methoxy-3-(N-(8-(2-(3-methoxyphenyl)-N-methylacetamido)-5,6,7,8-tetrahydronaphthalen-2-yl)sulfamoyl)phenyl)-N-(pyridin-4-yl)acrylamide ((R)-YNT-3708; EC50 = 7.48 nM for OX1R; OX2R/OX1R EC50 ratio = 22.5). Unlike the OX2R-selective agonist, the OX1R-selective agonist (R)-YNT-3708 exhibited antinociceptive and reinforcing effects in mice more potently than the dual agonist.
Upgrading the Detection of Electrocatalyst Degradation During the Oxygen Evolution Reaction
Authors: Risch Marcel
Published: October 2022

Electrocatalysts for the oxygen evolution reaction (OER) are an important component for the transition from fossil to sustainable energy. Commercialization of cost-effective earth-abundant electrocatalysts is in large parts hindered by their degradation. In this short review, I identify common processes leading to a decrease in electrocatalyst activity, followed by an introduction of staple methods to determine degradation electrochemically and by additional physical characterization, which has the potential to remove ambiguities of purely electrochemical studies. I conclude by a summary of the key challenges for an accurate determination of degradation processes and highlight interesting directions to advance the understanding of degradation processes on electrocatalysts.

Published: October 2022

We report a high-performance multi graphics processing unit (GPU) implementation of the Kohn-Sham time-dependent density functional theory (TDDFT) within the Tamm-Dancoff approximation. Our newly developed GPU algorithm on massively parallel computing systems using multiple parallel models in tandem scales optimally with material size, considerably reducing the computational wall time. A benchmark TDDFT study was performed on a green fluorescent protein complex composed of 4,353 atoms with 40,518 atomic orbitals represented by Gaussian-type functions. As the largest molecule attempted to date to the best of our knowledge, the proposed strategy demonstrated reasonably high efficiencies up to 256 GPUs on a custom-built state-of-the-art GPU computing system with Nvidia A100 GPUs. We believe that our GPU-oriented algorithms, which empower first-principles simulation for very large-scale applications, may render deeper understanding of the molecular basis of material behaviors, eventually revealing new possibilities for breakthrough designs on new material systems.

Published: October 2022

SQ109 is a tuberculosis drug candidate that has high potency against Mycobacterium tuberculosis and is thought to function at least in part by blocking cell wall biosynthesis by inhibiting the MmpL3 transporter. It also has activity against bacteria and protozoan parasites that lack MmpL3, where it can act as an uncoupler, targeting lipid membranes and Ca2+ homeostasis. Here, we synthesized 19 analogs of SQ109 and tested them against bacteria: M. smegmatis, M. tuberculosis, M. abscessus, Bacillus subtilis and Escherichia coli, as well as against the protozoan parasites, Trypanosoma brucei, T. cruzi, Leishmania donovani, L. mexicana and Plasmodium falciparum. Activity against the mycobacteria was generally less than with SQ109 and was reduced by increasing the size of the alkyl adduct, but two analogs were ~4-8 fold more active than was SQ109 against M. abscessus, including a highly drug resistant strain harboring a A309P mutation in MmpL3. There was also better activity than found with SQ109 with other bacteria and protozoa. Of particular interest, we found that the adamantyl C-2 ethyl, butyl, phenyl and benzyl analogs had 4-10x increased activity against P. falciparum asexual blood stages, together with low toxicity to a human HepG2 cell line, making them of interest as new anti-malarial drug leads. We also used surface plasmon resonance to investigate the binding of inhibitors to MmpL3, and differential scanning calorimetry to investigate binding to lipid membranes. There was no correlation between MmpL3 binding and M. tuberculosis or M. smegmatis cell activity, suggesting that MmpL3 is not a major target, in mycobacteria. However, some of the more active species decreased lipid phase transition temperatures, indicating increased accumulation in membranes, expected to lead to enhanced uncoupler activity.

Published: October 2022

Dried fishery products are popular processed food items throughout the world. Nowadays,
the demand for nutritionally rich and safe dried fishery products is increasing. A
substantial quality loss in dried fishery products occurs due to the chemical,
microbiological and non-enzymatic browning reactions during handling, processing,
drying, packaging, storage and distribution lead to influence the safety of the products.
However, factors influencing the quality and safety of dried fishery products are poorly
understood. Therefore, this review article discussed various quality and safety aspects of
dried fishery products, such as raw material quality and pre-treatment, drying methods,
additives use, extrinsic factors, irradiation, cold oxygen plasma treatment, corona
discharge plasma, high hydrostatic pressure, packaging methods and materials used,
storage condition and temperature, and so on, all of which have an impact on the final
product. The ultimate aim of this study was to gain a better understanding of the current
state of quality in dried fishery products and the techniques for improving it, which will
aid processors in ensuring the quality and safety of dried fishery products for consumers in
the long run. This review could also be used as a guide for future research and
development of dried fishery products as well as ensuring consumer’s safety for both
domestic and foreign markets.
Enculturalising Casteism in Health Care in India
Authors: Narayan Navin
Published: October 2022

Immunology depends on culturing technique, practice, and procedure. Society depends on culture. The change in the enculturing technique has always got promoted and accepted, while a change in Indian society is discouraged and not accepted despite claims of change happening. The ‘Society of India’ heavily depends on casteism and ensures all mechanisms for keeping it functional without change. By accepting culturing techniques from immunology, privileged Indian society developed a new technique with the old ethos that may be called ‘culturing casteism’. It has a deep presence in both spheres of health: ‘Sociology of Sufferer’, namely, the healthcare seeker and ‘Sociology of Supremacy’, namely, the healthcare profession and professional. This essay explores the way casteism is cultured in both spheres. The essay’s main aim is to understand and define the existence of casteism in health. The data establishes that the domination of privileged castes exists and is nurturing casteism in health. Privileged castes have captured the whole (health) sector while the dispossessed and deprived have been trying hard to ‘catch’ the care.

Authors: Raushan Rajesh , Acharya Sanghmitra S. , Raushan Mukesh Ravi
Published: October 2022

This study is on caste inequality in child health outcomes: mortality, malnutrition and anaemia for the year 1998/99 to year 2019/21 and examines the association of socio-economic factors with outcomes. Disparity ratio (DR) and Concentration Index (CI) are computed to examine inequality in outcomes. The association of socio-economic factors was modelled using logit regression. The study finds marginalised group were more likely to have poor health outcomes. The disparity ratio found increased among SC and ST compared to Others during 1998-99 and 2019-21. The value of the concentration index was found high on U5MR among SC and ST. Among SC and ST, the child health outcome greatly varies for poorest and richest. Odds ratio is 40-60 per cent higher for SC and ST compared to children belonging to Others. On socio-economic factors; land ownership and wealth status contribute significantly but house ownership not so. Caste-based inequality is still impacting health and nutrition of children in the country. The more focused inclusive policy and clustering of marginalised groups at regional level can be helpful in improving health and nutrition of marginalised children concentrated in different regions with equity lens to push the SDG Goals.

An analysis of the development of our relationship with death
Authors: Wadehra Sunidhi
Published: October 2022

This paper analyzes the development of our relationship to death over time as discussed by Freud, Mellor and Shilling, and Weber. This paper conducts an in-depth analysis  examining the internal structures of the theorists' specified work. Following the in-depth analysis, the paper overlays a lens of the “before” and “now” of our relationship to death on each theorist's argument. This paper then comparatively analyzes each theorist's argument weaving them together to create a meta-theory. This meta-theory explains missing pieces and brings together loose ends in theory in a harmonious synthesis.

ANALISIS EFISIENSI TEKNIS USAHATANI PADI LAHAN IRIGASI DI KABUPATEN LOMBOK BARAT
Authors: Wati Hernawati
Published: October 2022

Efisiensi merupakan suatu ukuran relatif dan abstrak, secara individual seorang produsen hanya akan menyadari hakekat efisiensi jika inefisiensi berlangsungnya dalam waktu yang cukup lama akan merugikan karena secara sosial terjadi pemborosan sumberdaya yang semakin langka seiring dengan meningkatnya kebutuhan dan adanya proses degradasi.Penelitian ini bertujuan untuk mengetahui tingkat efisiensi teknis pada penggunaan faktor produksi pada usahatani padi di lahan irigasi di Kabupaten Lombok Barat. Rata-rata tingkat efisiensi teknis dan rata-rata produktivitas  yang dicapai petani dalam usahatani padi sebesar 80 % dengan menggunakan analisis frontier yakni produktivitas maksimum yang dapat dicapai dengan sistem pengelolaan yang baik, artinya petani masih memiliki peluang sekitar 20 persen untuk mencapai tingkat efisiensi maksimal 100 persen. Tingkat Efisiensi Teknis yang tinggi mencerminkan prestasi petani dalam keterampilan manajerial cukup tinggi sehingga  penguasaan informasi dan pengambilan keputusan dalam mengelola faktor-faktor penting yang mempengaruhi produktivitas dapat tercapai secara maksimal. Tingkat efisiensi teknis yang sudah dicapai petani dalam menggunakan factor-faktor produksi sudah pada level yang memuaskan, namun mengingat jumlah penduduk setiap tahunnya terus bertambah yang berdampak pada peningkatan kebutuhan akan pangan khususnya beras maka untuk mempertahankan program ketahanan pangan maka perlu kebijakan pemerintah daerah untuk membuat rancangan baru khususnya tehnologi budidaya padi sehingga tingkat efisiensi yang nantinya bisa dicapai mendekati satu. Tingkat efisiensi yang tinggi juga merefleksikan bahwa peluang petani untuk meningkatkan produktivitas yang cukup tinggi semakin kecil karena perbedaan antara tingkat produktivitas yang telah dicapainya dengan tingkat produktivitas maksimum dengan sistem pengelolaan terbaik cukup kecil.

Authors: Fransiska Adik Emil , Hadiati Chusni , Muttaqin Usep
Published: October 2022

This research aims to identify the forms and functions of imperative utterances produced by Nadiya Hussain in the Netflix cooking show, Nadiya Bakes First Season. The data of this research are imperative utterances produced by Nadiya while delivering her recipes. The descriptive qualitative method and the technique of purposive sampling are applied to answer the research questions. Based on the analysis, there are 310 imperative utterances produced by Nadiya that can be analyzed according to Holmes in Richard and Schmidt’s (1983) theory of imperative form and Condoravdi and Laurer’s (2012) theory of imperative function. The results show that based on the imperative form, base form of verb highly appeared in the show because it has the simplest form and is usually explicit enough to prevent misunderstanding about the cooking instructions. Besides, verb ellipsis has no occurrence due to the help of visualization of Nadiya while delivering the instructions. Based on the imperative functions, commands function dominates in this show due to the effectiveness of the function which is directly expressed from utterances produced by Nadiya. Group IV: disinterest advice and group II: wish-type uses have the least occurrence because these functions do not have the expectation of the realization of imperative from the hearer, while the cooking show aims to get the viewers to follow the instructions given by Nadiya. After reading this research, hopefully, the readers can recognize the forms and functions of imperative utterances, not only employed in the cooking shows but also in their daily communication.

Published: October 2022

The signifi cance of assessing the quality of life (QoL) in patients with glaucoma among those with other ophthalmic diseases has been established based on the analysis of literature. Due to the high risk of complete loss of vision, it is important to stop the progression of glaucoma. To do this, developing disorders of visual functions are monitored by the level of QoL and disability. The literature emphasizes the importance of adequate control over the course of the disease and off ers various methods for assessing QoL. Nevertheless, the goal of fi nding more sensitive methods of the earliest clinical manifestations detection, remains unresolved. This problem is important for monitoring adherence to treatment, since the progressive vision deterioration due to glaucoma, aff ects QoL, so such monitoring is widely used in chronic diseases, which include glaucoma. Understanding the impact of the disease on the life of patients allows one to choose the right treatment strategy, improve cooperation with the patient and his compliance, that is, compliance with the doctor’s recommendations.

Penelitian ini bertujuan untuk menguji dan memprediksi kepercayaan dan komitmen pada relasi dekat dalam dua tahap studi. Studi 1 dilakukan untuk menguji jalur antara penyesuaian, dependensi, kepercayaan, dan komitmen pada relasi dekat dengan menggunakan Structural Equation Modeling (SEM). Studi 2 dilakukan untuk memprediksi tingkat kepercayaan dan tingkat komitmen dengan menambah jenis kelamin dan jenis relasi sebagai prediktor dengan implementasi Jaringan Saraf Tiruan (JST) model Multilayer Perceptron (MLP), yang dilakukan dalam 27 percobaan (3 hidden layer x 3 learning rate x 3 epoch) untuk masing-masing tingkat kepercayaan dan tingkat komitmen. Studi 1 dan Studi 2 dilakukan terhadap 417 responden (103 pria, 314 wanita; 97 pacaran, 320 persahabatan). Pengumpulan data dilakukan dengan menggunakan kuesioner adaptasi Revised Dyadic Adjustment Scale (11 aitem; α = 0,78), Investment Model Scale (15 aitem; αdependensi = 0,886; αkomitmen = 0,933), dan Trust in Close Relationship Scale (13 aitem; α = 0,917). Hasil Studi 1 menunjukkan pengaruh penyesuaian dan dependensi terhadap kepercayaan; serta pengaruh dependensi dan kepercayaan terhadap komitmen pada relasi dekat. Hasil studi 2 menunjukkan model JST terbaik untuk memprediksi tingkat kepercayaan ialah dengan konfigurasi 4 hidden layer units, 0,75 learning rate, dan 1000 epochs dengan tingkat akurasi sebesar 75,85%; sementara, model JST terbaik untuk memprediksi tingkat komitmen ialah dengan konfigurasi 4 hidden layer units, 0,75 learning rate, dan 2500 epochs dengan tingkat akurasi sebesar 79,95%.
