Female Island: Jean Rhys’s Wide Sargasso Sea
Authors: Kamalova Khatira
Published: January 2022

Two leading articles of feminist hue – “The Laugh of the Medusa” (1976) and “Feminist Criticism in the Wilderness” (1981) – by two seminal figures, Hélène Cixous and Elaine Showalter respectively, grant a new look at Jean Rhys’s novel Wide Sargasso Sea. Two main themes that come to the fore from these two articles with reference to Rhys’s novel are the male-dominated female zone and the importance of female writing for women. Both critics mention the strong hold of patriarchy on women, which is quite obvious in Antoinette’s condition in Rhys’s novel. Next, both Cixous and Showalter claim that while men see the female domain as a dark space, women should stick to their female domain and express themselves through writing. And this is what Rhys does in her novel; she gives a voice to the mad woman in the attic, Antoinette, who has been put there and tagged mad by her husband. By exploring the similarities between feminist criticism in Cixous’s and Showalter’s articles and Rhys’s novel, this study aims to show that although Wide Sargasso Sea is a revolutionary novel with its ability to give the mad woman back her individuality, it is not strong enough to create a world where this woman can experience her individuality.

Authors: Tudorache Paul , Raţiu Aurelian
Published: January 2022

As other society domains, the military one must be able to keep up with the dynamics of permanent changes and this necessity, shaping the capacity of adaptability, represents the most important criterion used to measure the military operational performance. In this regard, the present study aims to analyse one of the 4th Industrial Revolution’s consequences in the military field, as emerging and disruptive technologies (EDTs). Also, reviewing the scientific papers in the field and using an empirical research based on observation, the study will focus on clarifying the EDT concept, identifying the EDT agents in the military (NATO context) and, finally, analysing those EDTs suitable for the service of Land Forces in order to determine the potential impact in revolutionizing its combat capabilities.
Prediction of the EDT Trends – National and Supranational Activities
Authors: Viher Mladen , Paljević Marijan , Gernhardt Dalibor
Published: January 2022

Defence capabilities have always been heavily dependent on technological capabilities. This dependence is significantly emphasized nowadays due to the very rapid advancement of science and technology relevant to defence, and especially due to the emergence of disruptive technologies. However, emerging and disruptive technologies are well known throughout human history (fire, wheel, metals, gunpowder, external and internal combustion engines, etc.). Today, the cycle of emergence, application and response to the EDT is much faster, due to globalisation and maturation of information technologies. Smaller countries, because of their modest industrial and technological base at the national level, have problems to follow the emerging and disruptive technologies. In modern civilization, the military is losing its traditional centuries-old role as a privileged customer for purchasing new, technologically advanced products and must face competition in the open market. In this case, defence must be actively involved in monitoring and predicting technological trends, with an emphasis on disruptive technologies. Countries, especially those with strong armed forces and a long military tradition, have been doing this for a long time, but supranational activities (NATO and the EU) are relatively recent. These supranational activities are an important complement to national efforts and it is recommended that they should not be neglected by smaller NATO and EU member states.

Authors: Pătraşcu Petrișor
Published: January 2022

Today’s society is increasingly dependent on the facilities offered by new technologies. Thus, emerging technologies play a key role in people’s lives, as well as in the functionality and protection of infrastructures that ensure the availability of goods and essential services. Therefore, the exploitation of emerging technologies has become necessary even in the most sensitive sectors of activity, which have significant implications for ensuring national security. Artificial intelligence, Internet of Things, Big Data, robots, drones, machine learning and many more are feasible solutions for the dynamics and optimization of the environment in which they are integrated. The defence sector has also implemented a number of new technologies, integrating state-of-the-art digital systems into the communications architecture that are necessary for carrying out the military operations in a modern battlefield. Although, emerging technologies have a certain degree of uncertainty, they have already been adopted, and today premises are moving towards further innovation and development of emerging technologies by manufacturers that have an increasing interest to integrate them in the key areas of activity. This article provides an analysis of the impact of Internet of Things technologies on national security, in terms of critical infrastructure protection and the defence sector.

Authors: Putri Andayani Eka , Sarah Fitriani Siti , Fitrisia Dohra
Published: January 2022

This study aims to find out the perception of post-graduate students on plagiarism, the influenced factors, and the strategies used by the students to avoid plagiarism in thesis writing. To collect the data, 10 post-graduate students of Graduate Study of English Education at University of Syiah Kuala (USK) were chosen randomly based on the predetermined criteria: the students in the academic year 2016 and 2017 who have written their thesis. The data were collected through interviews. The result of data analysis shows that the post-graduate students of English Education at USK have the same perception about the issue of plagiarism in thesis writing. The factors contributing to plagiarism are limited time, the deadline, technological development and ease of accessing online sources, students' laziness, lack of understanding to paraphrase, and poor understanding of plagiarism. Furthermore, two main strategies can be used to avoid plagiarism in thesis writing. The first is paraphrasing and quoting other peoples' ideas. The second is reading a lot of sources from many articles and journals to learn how the authors develop their idea in their writing and how to put citations and references appropriately.

Authors: Saputra Rocky Harisman
Published: January 2022

This research aims to investigate a literacy program at a senior high school level. The researcher obtained the data for this research from Senior High School 4 in Banda Aceh because it has a better English teaching and learning process, and the school implemented a specific literacy program. The participants involved in this research include the school principal, vice school principals, the head of the school library, teachers, and 20 students from science and social science classes. The data in this research was collected using an observation sheet and interview guide to evaluate the literacy program based on the CIPP framework. The research results show that the literacy program at the school includes learning strategies provided by the teacher, the availability of facilities, and student reading interest. Based on the interview results, students were not motivated to participate in the school literacy program. Therefore, it is suggested that specific policy needs to be made and reinforced in order to implement a literacy program at senior high schools.

Authors: Бондарь Игорь Александрович , Ленькова Екатерина Николаевна
Published: January 2022

Статья посвящена введению в научный оборот новых петроглифов Улуг-Хемской котловины, реки Енисей в Республике Тува. Главный объект исследования - новый памятник наскального искусства - святилище священной горы Ала-Тей. Новый памятник расположен на отдельно стоящей сопке, называемой - «гора Ала-Тей», и локализуется между хребтом Западный Саян и Танну-Ола в Улуг- Хемской котловине Верхнего Енисея. Наскальные изображения горы Ала-Тей находят прямые аналоги в наскальном искусстве Тувы и других регионов Центральной Азии и Южной Сибири. В то же время, изображения являются уникальными, а некоторые из них не обнаруживают прямых аналогий среди петроглифов Улуг-Хемской котловины и Саянского каньона реки Енисей. В процессе исследования были выявлены: сюжет «священного брака» двух антропоморфных фигур, изображения оленей, быков, изображения рогов, астральных и космогонических символов и тамгообразные знаки. Обнаруживается большое количество сцен взаимодействий животных бронзового века, скифского и древнетюркского времени. Был произведён сравнительный анализ с известными петроглифами Тувы и сопредельных регионов, таких как: Красноярский край, Хакассия, Алтай, Байкальский регион и Монголия. Научная работа авторов призвана пролить свет на историю священной горы Ала-Тей и её сакральное наскальное искусство.
Transzendente Begegnungen (eBook)
Authors: Schwenke Heiner
Published: January 2022

Transzendente Begegnungen wurden von der Wissenschaft bisher weitgehend ignoriert oder als illusionär und irreal betrachtet. Die Zeugnisse nachhaltiger biographischer Wirkungen von Begegnungen mit Personen aus anderen Welten, wie etwa verstorbenen Menschen oder Engeln, verweisen aber auf die unbezweifelbare Bedeutung dieser Erfahrungen. Das Buch bietet eine umfassende Phänomenologie transzendenter Begegnungen, die auf eine Untersuchung zahlreicher Erlebnisberichte gründet. Schwenke erörtert die Kritik dieser Erfahrungsform durch Wissenschaft und Religion und kommt zum Ergebnis, dass Wissenschaft die Realität transzendenter Begegnungen weder widerlegen noch beweisen kann. Der klassisch beweisorientierte Ansatz ist verfehlt. Die betroffene Person darf und muss sich auf ihr eigenes Erfahrungsurteil verlassen. Die pauschale Pathologisierung ihrer Erfahrungen beruht nicht auf wissenschaftlichen Erkenntnissen, sondern auf fragwürdigen weltanschaulichphilosophischen Grundannahmen und ist daher unbegründet. Von religiöser Seite werden transzendente Begegnungen häufig als Illusionen angesehen, die nicht nur unwahr, sondern auch schlechten, ja teuflischen Ursprungs sind. Die religiöse Abwertung von Erlebnissen dieser Art scheint weniger durch sachliche Gründe motiviert zu sein als durch das Bestreben, ein Monopol der eigenen Religion, insbesondere ihrer Amtsträger, auf den Zugang zur Transzendenz zu etablieren und aufrechtzuerhalten. Abschliessend werden einige Vorschläge zum philosophischen Verständnis transzendenter Begegnungen auf der Grundlage der Erlebnisberichte gemacht.
Die neue Reihe Schwabe Mystica ist der Erforschung transzendenter (mystischer, religiöser, spiritueller) Erfahrungen und ihrer Deutungen und Wirkungen in Kultur, Kunst, Philosophie und Religion gewidmet. Sie ist weltanschaulich unabhängig und durch Interdisziplinarität und Methodenvielfalt geprägt. Die einzelnen Bände zeichnen sich durch ein hohes wissenschaftliches Niveau und eine klare, ansprechende Darstellung aus. Die Reihe umfasst Monographien, Editionen bisher ungedruckter Schriften und auch Sammelwerke.

Authors: Damayanti Cacik Rut , Nuzula Nila Firdausi , Sulasmiyati Sri , Maharani Amalia Agista
Published: January 2022

This study aims to acknowledge how environmental performance, corporate governance, competitive advantage, and financial performance-linked each other in Japan. The data used are data from chemical, pharmaceutical, and machinery sub-sector companies listed on the Japan Exchange Group 2013 - 2018. This research was explanatory research using a quantitative approach and implemented Partial least Square (PLS). This study found that the board of directors and firm performance have no significant effect on the company's environmental performance, while corporate control and ownership structure provide a different result. Then, environmental performance and ownership structure have been proven to bring a significant contribution to the company's competitive advantage. Reflecting on Japan, this study suggests several recommendations to the Indonesian Ministry of Environment and Forestry to develop environmental conservation schemes and concepts implemented by public companies in Indonesia and the Indonesian Ministry of Finance to develop applicable environmental accounting concepts for public companies in Indonesia.

On Some Approximation Properties for a Sequence of λ-Bernstein Type Operators
Authors: Muhammad Ali Jassim , Jaber Asma
Published: January 2022

In 2010, Long and Zeng introduced a new generalization of the Bernstein polynomials that depends on a parameter  and called -Bernstein polynomials. After that, in 2018, Lain and Zhou studied the uniform convergence for these -polynomials and obtained a Voronovaskaja-type asymptotic formula in ordinary approximation. This paper studies the convergence theorem and gives two Voronovaskaja-type asymptotic formulas of the sequence of -Bernstein polynomials in both ordinary and simultaneous approximations. For this purpose, we discuss the possibility of finding the recurrence relations of the -th order moment for these polynomials and evaluate the values of -Bernstein for the functions ,  is a non-negative integer
Eosinophilic esophagitis in children: Updates and practical aspects of management for allergists in a non‐tertiary care private practice setup
Authors: Yousef Ejaz , Korotkaya Yelena , Simpson Alyson B.
Published: January 2022

Background: Eosinophilic esophagitis (EoE) is a chronic immune and/or antigen-mediated disease characterized by eosinophilic infiltration of mucosa (≥15 eosinophils per high power field) without any secondary etiology. Non‐immunoglobulin E mediated mechanisms predominate
in EoE. Objective: This review concentrated on a stepwise approach for the allergist working in non‐tertiary care private practice. Methods: A medical literature search that focused on several areas of the latest developments in the diagnosis
and management of EoE was conducted. Results: There has been a steady increase in the prevalence and incidence of EoE. Clinical symptoms can vary from dysphagia to failure to thrive, depending on the age at presentation; some children develop adaptive behaviors to compensate
for dysphagia, such as food preferences and slow eating. The diagnosis is based on a high index of clinical suspicion and is confirmed with endoscopy with biopsies after ruling out other causes of esophageal eosinophilia. Treatment options may include dietary therapy, pharmacologic therapies,
or combination therapy. Therapeutic options may also include endoscopic dilation for stricturing disease. Conclusion: Providers should be aware of recent recommendation changes in the diagnostic workup, the role of skin-prick testing, and role of the proton-pump inhibitor
as first-line therapy for EoE. Also, clinicians should be aware of the emerging role of empiric dietary therapy as a preferable therapeutic option when compared with the testing-directed diet and the elemental diet. Furthermore, topical glucocorticoid therapies are available, and new developing
therapies are being investigated. Reevaluation of esophageal mucosa with biopsies is required approximately 2 months after therapy for a response and after a change in therapies to confirm continued resolution.
Monitored COVID-19 mRNA vaccine second doses for people with adverse reactions after the first dose
Authors: Gallagher Megan C. , Haessler Sarah , Pecoy-Whitcomb Elizabeth , Bayuk Jonathan
Published: January 2022

Background: After Emergency Use Authorization of the coronavirus disease 2019 (COVID-19) vaccines, guidance was provided by the Centers for Disease Control and Prevention that persons with an immediate allergic reaction to a messenger RNA (mRNA) COVID-19 vaccine should be
evaluated by an allergist/immunologist before receipt of the second dose. Methods: In vaccinating health-care personnel, we referred those with significant reactions to allergy/immunology specialists so that they could safely receive the second dose. Results:
We found that many reactions after the first dose were nonallergic but could be debilitating and a barrier to the second dose. We created a protocol of premedications to allow health-care personnel to safely receive their second mRNA COVID-19 vaccine dose. Conclusion: This
protocol is adaptable and can be used in settings where allergy/immunology referral is not immediately available.

Relationship of maxillary and mandibular effective base length, arch length and dental crowding in different vertical growth pattern
Authors: Satra Priyanka , Vichare Gauri , Bhosale Veera
Published: January 2022

Objectives:

The objectives of the study were to assess, measure, and correlate the maxillary and mandibular effective base length, arch length to the amount of dental crowding in different vertical growth pattern patients.

Materials and Methods:

Sample comprising 100 pre-treatment lateral cephalograms and study models (age group – 16–25 years) was randomly selected. The sample was divided into two groups, that is, clockwise (50) and anticlockwise (50) rotation based on the measurement of the gonial angle. The gonial angle and maxillary and mandibular effective lengths were measured on pre-treatment lateral cephalograms. Dental crowding and arch length were measured on the pre-treatment dental casts. Intergroup comparisons of effective base length, arch length, and crowding were performed with unpaired t-tests. Correlations between effective base length, arch length, and dental crowding were examined by means of Pearson’s correlation coefficient (P < 0.05).

Results:

Subjects with clockwise rotation significantly had more mandibular dental crowding and significantly decreased mandibular arch length compared to the anticlockwise group. An inverse correlation was found between maxillary and mandibular effective base length, arch length, and dental crowding while a positive correlation was found between maxillary and mandibular base length and arch length in both the groups.

Conclusion:

Clockwise rotation of the mandible along with skeletal and dental factors such as decreased effective base lengths and arch length, respectively, constitutes an important factor leading to dental crowding.
Lessons learned from a fatal case of tuberculous meningitis with a rapid decline in an infant
Authors: Shah Heema , Joshi Ashwini , Dobish Emilee , Thomas Anna Kalathil
Published: January 2022

Tuberculous meningitis is a highly lethal, often underrecognized disease with characteristic clinical and imaging features which can be cured if the diagnosis and subsequent treatment are begun at early stages. Frequently, there is a delayed diagnosis of this condition due to unfamiliarity of clinicians in non-endemic areas about its presentation and diagnostic workup. This article presents a case of rapid decline and fatality due to tuberculous meningitis in an 11-month-old child from a non-TB-endemic area and describes the characteristic clinical presentation, imaging findings, and diagnostic pitfalls associated with this condition.
Solitary bone plasmacytoma as posterior fossa cranial neoplasia, presentation of two clinical cases
Authors: Andaluz Luis David Molina , Gonzalez Josué Alejandro Cervantes , Ramírez Zita Elizabeth Salazar , Ramírez Nelly , Castellanos Luis Guillermo , Estrada Eric Misael Estrada
Published: January 2022

Background:

Solitary bone plasmacytoma is a plasmatic cell dyscrasia; its presentation in the posterior fossa is very rare.

Case Description:

We present two cases, a 59-year-old male and a 50-year-old female, both with heterogeneous clinical presentation. One had symptoms compatible with endocranial hypertension, and the other presented with a hemispheric cerebellar syndrome and ipsilateral trigeminal neuralgia. They were both related to an intraosseous tumor of the occipital region near the torcula with large extension to the posterior fossa. The diagnosis of a plasma cell neoplasm arising from the diploe of the squamous portion of the occipital bone was confirmed with immunohistochemistry.

Conclusion:

The treatment for a cranial tumor that is suspected to be a solitary bone plasmacytoma requires a multidisciplinary team to diagnose, plan a total resection, and after surgery continue with the follow-up of the patient. Solitary bone plasmacytoma should be considered as a differential diagnosis for a tumor that produces cancellous bone widening without sclerotic borders.
Depositional mode and Provenance of Kopili sandstones from parts of Dima Hasao District, Assam, NE India: Evidence from Grain size distribution and Heavy mineral assemblage
Authors: Mout Joya Moni , Sarmah Ranjan Kumar
Published: January 2022

This study presents a record of the depositional mode and provenance of the Kopili sandstones outcropped in and around Umrangso, the Dima Hasao district of Assam, India using proxies such as grain size and heavy mineral study. The Grain size study reveals that the sandstones of the Kopili formation consist predominantly of fine-grained sands mixed with medium sands. The grain size statistical parameters divulge that the sandstones are characterized mostly by moderately sorted sands, coarse skewed to near symmetrical, leptokurtic to extremely leptokurtic nature. The frequency distribution curves reflect mostly bimodal as well as polymodal distribution of sediments. The Linear Discriminant Function analysis indicates shallow marine beach sub environment in agitated water depositional condition for the Kopili sediments. The CM pattern discloses that saltation and suspension are the dominant transporting modes. The Heavy mineral analysis discerns that opaques dominate over transparent heavies. Transparent heavies in decreasing order of abundance are zircon, tourmaline, rutile, clinopyroxene, staurolite, hornblende, garnet, chlorite and epidote. The zircontourmaline- rutile (ZTR) maturity index (average 53.15%) discloses sub-mature to mature nature of the Kopili sandstones. The heavy mineral assemblage corroborates their mixed provenance (silicic igneous and metamorphic) for the Kopili sandstones.
SSR based molecular profiling of elite cultivars of basmati rice (Oryza sativa L.)
Authors: Yadav Ashwani , Sharma Anubhuti , Kumar Ashwani , Yadav Renu , Kumar Rajendra
Published: January 2022

The experiment was conducted to assess the available genetic variability amongst Indian Basmati rice and identify co-dominant and reproducible robust simple sequence repeat markers for drought resistance and their utilization in marker assisted selection for developing drought resistant / tolerant aromatic rice cultivars in various parts of India as well as in world. DNA was isolated from fresh and young leaf tissues of 35 cultivars of basmati rice using the CTAB procedure of Doyle and Doyle with slightly modifications. The DNA was further quantified by spectrophotometer at 260 nm and 280 nm. The quality and quantity of DNA were checked by agarose gel electrophoresis. Out of 60 SSR markers, 18 were found to be polymorphic and the rest 42 primers were monomorphic. One of the main purposes of SSR markers in genomic study is the characterization of genetic resources to help gene bank management. The informative (18) SSR markers were capable to discriminate the entire cultivars of basmati rice used in this research work. A total of 52 alleles at 18 loci could be scored. The allelic richness per locus diversified from 2 to 5 with an average of 2.89 alleles per locus. The amplitude of Polymorphism Information Content (PIC) value is 0.066 (RM 1068) to 0.730 (RM 1059) with an average of 0.505. The Jaccard’s similarity coefficient ranged from 0.79 to 0.95. Polymorphic finding content showed a positive correlation (r =0.69) with number of alleles at the SSR locus. However it is recommended that SSR markers can be efficiently utilized for this purpose. The maximum similarity coefficient was observed between Jeerakasab and Kalanamak with a coefficient value of 95% and the minimum similarity was found between Jeerakasab and Pusa basmati-1 with a coefficient value of 79%.
Palaeoclimatic significance of non - striate disaccate pollen in Yellandu coalfield of Godavari graben, Telangana State
Authors: Seetharam D.S. , Ramakrishna H.
Published: January 2022

The present palaeopalynological study deals with the significance of non - striate disaccate pollen from bore hole Q - 563 of Yellandu coalfield (Jawahar Khani - 5 coal block), Kothagudem sub-basin and to determine the age and palaeoclimatic interpretations of the study area based on the pollen morphological characters. For the palynological investigation, sixty samples were thoroughly analyzed in which fairly diversified palynofloral assemblages of Gondwanic affinity were recorded. About 30 genera and 50 species of palynomorphs, belong to Glossopteridales, Coniferales, Cordaitales of gymnospermous pollen, pteridophytic spores. In the present communication, the palynoflora belongs to Glossopteridales viz. Scheuringipollentites barakarensis, S. maximus, S. tentulus, Ibisporites diplosaccus, Primuspollenites levis, P. densus and Sahnites thomasii etc. Frequency distribution pattern of the palynotaxa reveals that the assemblage is dominated by the non - striate disaccates followed by striate disaccates, monosaccates (gymnosperms) and pteridophytic spores. The diversified palynoassemblage of both non striate and striate disaccates pollen strongly signifies that the Yellandu coal belt of Godavari graben belongs to Barakar Formation of Early Permian age (Late Sakmarian – Early Artinskian). Predominance of non - striate disaccate pollen recorded from the Yellandu sediments indicates a warm and high humid climatic condition with fluvial environment of deposition.
Reduction of Colour from effluents of Pulp and Paper Industry by Ozonation: A Review
Authors: Tripathy Upendra Prasad , Bishoyi Sunil Kumar
Published: January 2022

Pulp and paper making is the major old process industry in India which is water intensive and generates heavy water pollution. Pulp and paper industries are the fifth largest contributor to industrial water pollution. Waste water is generated from each and every section of paper making process and depends upon the type of pulping and bleaching process. Presently, primary and secondary (Biological) treatment systems based on activated sludge process are widely used by paper industry for effluent treatment. The process requires high energy and chemical inputs and involves high operational costs. One of the novel processes for treating effluent is its oxidation through ozonation which is a greener way of degrading pollutants. Ozonation of intermediate stage effluents having high colour load is more effective for industrial application and re-utilization.

A phytochemical study of dichloromethane extract of Alphonsea elliptica has led to the isolation of two compounds previously unreported from the species methyl syringate and isovanilic acid. Stigmasterol which has been previously reported was also isolated. The structures were determined by spectroscopic techniques and by comparison with data reported in the literature. The findings of this study will contribute to the chemotaxonomic and phylogenetic aspects of the Alphonsea sp.
Density Functional Study of the Reaction Pathways of the Decomposition of Azidoborane: A Curtius-type Rearrangement
Authors: Parashar Renu , Bansal Sunita
Published: January 2022

Density functional study is used for the decomposition of azidoborane and the possibility of borylnitrene being an intermediate in the formation of iminoborane both in the singlet and triplet state. Our calculations has shown that in the one step concerted manner, both singlet and triplet azidoborane can lead to the formation of iminoborane. A two step path (nitrogen loss followed by isomerization of borylnitrene) is a first order saddle point on the energy surface. However, such a two step process is possible for the triplet azidoborane, since triplet borylnitrene corresponds to a energy minimum on the potential energy surface.

Increasing religious knowledge activities are routine things that are followed every week, this is aimed at strengthening Islamic and religious members of the education council.

Education council (majelis taklim) is a form of education that emphasizes to increase spiritual potential and forming students or worshipers to become human beings who believe, fear Allah and have noble character. Noble character includes ethics, character, and morals as manifestations of religious education. Increasing spiritual potential includes practicing, understanding, and planting religious values, as well as practicing those values in individual life or community collectives.

The purpose of this research to determine the level of participation of the education council in increasing religious of knowledge about reproductive health and knowing the level of participation of the education council.

The research method used descriptive qualitative by participatory action research (PAR) at education council in Banten, Indonesia and sampling technique by random sampling as a member of education council. 

The summary of this research showed that the level of religious knowledge about the reproductive health of the assisted participants is good that it gives a psychological impulse to register for early detection of reproductive disease. The woman reproductive health can improve by education council participation.

Piezoelectrically Mediated Reversible Addition-Fragmentation Chain Transfer Polymerization
Authors: Ding Chengqiang , Zhang Zhengbiao , wang zhao
Published: January 2022

A well-controlled piezoelectrically mediated reversible addition-fragmentation chain transfer polymerization (piezo-RAFT) was carried out under ultrasound agitation with piezoelectric ZnO nanoparticles as the mechano-chemical trans-ducer. The resulting polymer had predictable molecular weight, high end-group fidelity, low dispersity, and capacity for chain extension. This chemistry was further adopted in curing composite resins to circumvent the light penetration limit of UV curing. This work opened a new avenue of piezoelectrically mediated chemistry and showed its good potential in curing applications.

Bromination of high-pressure high-temperature (HPHT) nanodiamond (ND) surfaces has not been explored and can open new avenues for increased chemical reactivity and diamond lattice covalent bond formation. The large bond dissociation energy of the diamond lattice-oxygen bond is a challenge that prevents new bonds from forming and most researchers simply use oxygen-terminated ND (alcohols and acids) as a reactive species. In this work, we transformed a tertiary alcohol-rich ND surface to an amine surface with 50% surface coverage and was limited by the initial rate of bromination. We observed that alkyl-bromide moieties are highly labile on NDs and are metastable as previously found using density functional theory. The instability of the bromine terminated ND is explained by steric hindrance and poor surface energy stabilization. The strong leaving group properties of the alkyl-bromide intermediate were found to form diamond-nitrogen bonds at room temperature and without catalysts. The chemical lability of the brominated ND surface led to efficient amination with NH3•THF at 298 K, and a catalyst-free Sonogashira-type reaction with an alkyne-amine produced an 11-fold increase in amination rate. Overlapping spectroscopies under inert, temperature-dependent and open-air conditions provided unambiguous chemical assignments. Amine-terminated NDs and folic acid were conjugated using sulfo-NHS/EDC coupling reagents to form amide bonds, confirming that standard amine chemistry remains viable. This work supports that a robust pathway exists to activate a chemically inert diamond surface at room temperature, which broadens the pathways of bond formation when a reactive alkyl-bromide surface is prepared. The unique surface properties of brominated and aminated nanodiamond reported here are impactful to researchers who wish to chemically tune diamond for quantum sensing applications or as an electron source for chemical transformations.
Multi-active Site Dynamics on a Molecular Cr/Co/Se Cluster Catalyst
Authors: Kephart Jonathan , Mitchell Benjamin , Kaminsky Werner , Velian Alexandra
Published: January 2022

This study provides detailed insights into the interconnected reactivity of the three catalytically active sites of an atomically precise nanocluster Cr3(py)3Co6Se8L6 (Cr3(py)3, L = Ph2PNTol–, Ph = phenyl, Tol = 4-tolyl). Catalytic and stoichiometric studies into tosyl azide activation and carbodiimide formation enabled the isolation and crystallographic characterization of key metal-nitrenoid catalytic intermediates, including the tris(nitrenoid) cluster Cr3(NTs)3, the catalytic resting state Cr3(NTs)3(CNtBu)3, and the mono(nitrenoid) cluster Cr3(NTs)(CNtBu)2. Nitrene transfer proceeds via a stepwise mechanism, with the three active sites engaging sequentially to produce carbodiimide. Comparative structural analysis and CNtBu bind-ing studies reveal that the chemical state of neighboring active sites regulates the affinity for substrates of an individual Cr-nitrenoid edge site, intertwining their reactivity through the inorganic support.
