The design of catalysts with stable and finely dispersed platinum on the carbon support is key in controlling the performance of fuel cells. In the present work, an intermetallic PtCo/C catalyst with a narrow particle size distribution synthesized via double-passivation galvanic displacement is demonstrated. The catalyst exhibits an improved high-current-density performance in single-cell low-temperature fuel cell tests. TEM and XRD confirm a significantly narrowed particle size distribution for the catalyst particles in contrast to commercial benchmark catalysts (Umicore PtCo/C 30 and 50 wt%). Only about 10 % of the mass fraction of PtCo particles show a diameter larger than 8 nm, whereas up to > 35 % for the reference systems. This directly results in a considerable increase in electrochemically active surface area (96 m² g-1 vs. < 70 m² g-1). In addition, a higher fraction of these finely distributed PtCo nanoparticles are anchored on the carbon surface compared to the industrial benchmarks where nanoparticles are located inside the carbon pores. Single-cell tests confirm this finding by a significantly improved performance, especially at high current densities (~ 1 W cm-2 at 0.55 V under H2/air, 50 % RH, 250 kPaabs) and even with lower Pt loading (0.25 mgPt cm-2) compared to the commercial reference (< 0.9 W cm-2 at the same potential and the given conditions) with a higher Pt loading (0.4 mgPt cm-2). Lastly, reducing the cathode catalyst loading from 0.4 to 0.25 mg cm-² resulted in a power density drop at application-relevant 0.7 V of only 4 % for the novel catalyst, compared to the 10 % and 20 % for the Umicore reference catalysts with 30 wt% and 50 wt% PtCo on carbon.

Using water as monomer in polymerization reactions presents a unique and exquisite strategy towards more sustainable chemistry. Herein, the feasibility thereof is demonstrated by the introduction of the oxa-Michael polyaddition of water and divinyl sulfone. Upon nucleophilic or base catalysis, the corresponding aliphatic polyethersulfone is obtained in an interfacial polymerization at room temperature in high yield (> 97%) within an hour. The polyethersulfone is characterized by relatively high molar mass averages and a dispersity around 2.5. The polymer was tested as a solid polymer electrolyte with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) as salt. Free standing amorphous membranes were prepared by a melt process in a solvent free manner. The polymer electrolyte containing 15 wt.% LiTFSI featured an oxidation stability of up to 5.5 V vs. Li/Li+ at 45 °C and a conductivity of 1.45 × 10-8 S/cm at room temperature.

We developed acid-functionalized glycogen conjugates as supramolecular carriers for efficient encapsulation and inhibition of a model cationic peptide melittin - the main component of honeybee venom. For this purpose, we synthesized and characterized a set of glycogens, functionalized to various degrees by several different acid groups. These conjugates encapsulate melittin up to a certain threshold amount, beyond which they precipitate. Computer simulations showed that sufficiently functionalized conjugates electrostatically attract melittin, resulting in its efficient encapsulation in a broad pH range around the physiological pH. Hemolytic assays confirmed in vitro that the effective inhibition of melittin’s hemolytic activity occurs for highly functionalized samples, whereas no inhibition is observed when using low-functionalized conjugates. It can be concluded that functional glycogens are promising carriers for cationic molecular cargos or antidotes against animal venoms under conditions, in which suitable properties such as biodegradability and biocompatibility are crucial.

A deaminative reductive coupling of amino acid pyridinium salts with aryl bromides has been developed to enable efficient synthesis of noncanonical amino acids and diversification of peptides. This method transforms natural, commercially available lysine, ornithine, diaminobutanoic acid (DAB), and diaminopropanoic acid (DAP) to aryl alanines and homologated derivatives with varying chain lengths. Attractive features include scalability, tolerance of pharma-relevant (hetero)aryls and functional groups, applicability to both monomeric amino acid and short peptide substrates, and compatibility with biorthogonal handles useful for chemical biology. Furthermore, these cross-couplings can be conducted in microscale and nanoscale and are amenable to solid-phase peptide synthesis platforms. The success of this work relied on an academic/industry collaboration and high-throughput experimentation to identify complementary conditions that proved critical for achieving broad scope of aryl bromides and pyridinium substrates.
Role of Electronic Passivation in Stabilizing Solid Electrolyte Interphases
Authors: Li Yuheng , Canepa Pieremanuele , Gorai Prashun
Published: March 2022

The solid-electrolyte interphase (SEI) is crucial to the electrochemical performance of all-solid-state batteries (ASSBs). Theoretical characterization of SEI properties will help understand the origin of interfacial stability (and instability) between solid electrolytes and electrodes. Among solid electrolytes for Lithium(Li)-ion ASSBs, the lithium phosphorus oxynitride LixPOyNz (LiPON) is one of the most stable against Li metal anode. However, it has been shown that LiPON reacts with Li metal and forms SEIs. The SEI formation stops after a thin layer is formed, but the mechanism that enables this apparent stabilization is unclear. Thermodynamics underpins the defect formation in materials and in turn, creation of electronic charge. Materials for energy storage, including solid electrolytes, are no exception to this fundamental process. Here, we computationally evaluate the electronic passivation of SEIs and its role in stabilizing the Li-LiPON interface. Specifically, we determine the defect and charge carrier concentrations in Li-LiPON SEIs, including Li2O, Li3N, Li3P, and Li3PO4. The defect and charge carrier concentrations were calculated from defect thermodynamics. We then predicted the electronic conductivity of the SEIs under different electrochemical conditions, which correspond to varying potentials to the Li metal anode. Our results reveal that the stoichiometrically abundant and uniformly distributed Li2O has expectedly negligible electronic conductivity, while the electronically conducting components, such as Li3N and Li3P, show preferential distribution in the SEI. We posit that the overall electronically insulating nature of the SEI is responsible for the stability of the Li-LiPON interface. The computational approach adopted here can be extended to reveal the origin of the interfacial stability in other ASSBs.
Atroposelective arene-forming alkene metathesis
Authors: Jončev Zlatko , Sparr Christof
Published: March 2022

Alkene metathesis catalysed by enantiopure metal alkylidene complexes enables versatile strategies to products with configurationally-defined stereocentres. Desymmetrisation processes thereby provide particularly reliable stereoselective routes to aliphatic structures, while the differentiation of aromatic stereogenic units remained an outstanding challenge. Herein, we describe the feasibility of alkene metathesis to catalytically control stereogenic axes by traceless arene formation. Stereodynamic trienes are selectively converted into corresponding binaphthalene atropisomers upon exposure to a chiral molybdenum catalyst. Remarkably, stereoselective arene-forming metathesis allows high yields and enantioselectivities of up to 98:2 e.r. As the disconnection of each bond of aromatic products is retrosynthetically conceivable, it is anticipated that forging arenes by means of stereoselective metathesis will enable versatile approaches for the synthesis of a broad range of molecular topologies with precisely defined configuration.

Published: March 2022

Critical thinking and Decision-making skills are the crucial skills in the Comprehensive Patient care system where the ability of Physician and nurses is to provide high-quality, safe care depending upon their ability to think, reason, and judge critical clinical situations. Nurse Practitioners, Nurse Educators, and Nurse administrators are required for managing the dynamic health care system along with advancing excellence at every level of patient care in all levels of clinical settings by applying the skills of CT (critical thinking) along with DM (decision making). This narrative review summates the present scientific knowledge state concerning decision-making and critical thinking skills in nursing. Numerous keywords, as well as Mesh terminology, have been used to search Google Scholar and Pubmed databases. Additionally, the relevant lists of reference articles have been examined. In clinical practice, using critical thinking along with decision-making skills enhances professional action based on evidence as well as develops such areas of profession relevant to competence, according to the findings. In terms of providing safer, more competent service, the CT skills’ acquisition may help to increase diagnostic precision along with decision making, resulting in better results for patients. Nonetheless, in clinical practice, our literature review revealed that there are just a few studies investigating CT. Improved CT skills may enhance patient quality care, however, the exact relationship between CT as well as outcomes is yet unknown.

The present study consists of the comparative analysis of infiltration rates of soils under different land-cover conditions (dirt trails, grass plots and different types of forest stands) on the inner slopes of the Sfânta Ana crater, the catchment area of Lake Sfânta Ana in Romania. According to historical data, the depth and the surface of Lake Sfânta Ana have been undergoing significant changes during the last century, it lost in depth and the surface area shrunk approximatively 1,5 hectares. The losses are considered to be the consequences of the sedimentation as a result of the inflow processes from the catchment area, reduction of water level and eutrophication. The assessment and comparative analysis of steady infiltration rates of soils under different land-use categories in the catchment area were carried out to identify the possible sources of generation of surface flows responsible for sediment transport towards the lake using In Situ determinations with Double Ring Infiltrometers (DRI). Statistically significant differences were found between samples collected from grass plots, forests and the dirt trails, and within different forest stand structures. Results show that dirt trails and grass plots can be held responsible for the generation of surface flows. The main cause of low infiltration rates is soil compaction. Different forest stands are characterized by steady infiltration rates with high values and therefore provide effective protection. High forest coverage must be maintained in the crater, the problem of soil compaction on grass plots and dirt trails must be addressed.

New geological data on the Orlea mining field, Roșia Montană ore deposit, Romania were obtained by fieldwork carried out in the underground level +730 m, where three types of mineralized structures hosted by the Vent Breccia formation were studied, i.e., (i) flatly dipping vein with rhodochrosite gangue, (ii) steeply dipping tectonic breccia dyke, and (iii) steeply dipping base metal vein, respectively. The Vent Breccia is a polymictic matrix-supported breccia with sedimentary (clay, sandstone), volcanic (dacite), and metamorphic (quartzite, garnet micaschist) clasts. Four types of hydrothermal alterations were identified, i.e., (i) K-metasomatosis (adularia I); (ii) phyllic alteration (sericite); (iii) silicification; and (iv) potassic alteration (adularia II). The ore mineral assemblage consists of electrum, pyrite, chalcopyrite, sphalerite, galena, and minor arsenopyrite and pyrrhotite. The higher-grade ore body is the intermediate-sulfidation flatly dipping vein with rhodochrosite gangue grading up to 101g/t Au. The tectonic breccia dyke is a low-sulfidation ore body illustrating the evolution from early banded vein structure to late/final open-space clast supported tectonic breccia dyke.
Retrograde transport of CDMPR depends on several machineries as analyzed by sulfatable nanobodies
Authors: Buser Dominik P , Bader Gaétan , Spiess Martin
Published: March 2022

Retrograde protein transport from the cell surface and endosomes to the TGN is essential for membrane homeostasis in general and for the recycling of mannose-6-phosphate receptors (MPRs) for sorting of lysosomal hydrolases in particular. We used a nanobody-based sulfation tool to more directly determine transport kinetics from the plasma membrane to the TGN for the cation-dependent MPR (CDMPR) with and without rapid or gradual inactivation of candidate machinery proteins. Although knockdown of retromer (Vps26), epsinR, or Rab9a reduced CDMPR arrival to the TGN, no effect was observed upon silencing of TIP47. Strikingly, when retrograde transport was analyzed by rapamycin-induced rapid depletion (knocksideways) or long-term depletion by knockdown of the clathrin adaptor AP-1 or of the GGA machinery, distinct phenotypes in sulfation kinetics were observed, suggesting a potential role of GGA adaptors in retrograde and anterograde transport. Our study illustrates the usefulness of derivatized, sulfation-competent nanobodies, reveals novel insights into CDMPR trafficking biology, and further outlines that the selection of machinery inactivation is critical for phenotype analysis.

Mitochondrial ATP synthase is a macromolecular nanomachine, which produces most of the ATP in the cell. This enzyme is located in inner mitochondrial membrane in the form of dimers, which assemble into long rows at the cristae rims. Dimers of ATP synthase are sensitive to detergent treatment in many organisms, as a result of which they mainly dissociate into monomers. Plant enzyme is also very detergent-sensitive, nevertheless, it can be assumed that the detergent-sensitivity or, vice versa, detergent-stability of the enzyme under the treat-ment may vary in different plant species. In this regard, the aim of this work was to study the detergent-stability, as well as the activity of various forms of ATP synthase, solubilized from the mitochondria of different plant species. For this purpose, we used organelles isolated from etiolated pea, winter wheat, and maize shoots. These species belong to different families (Poaceae and Fabaceae), clades (monocots and dicots) and, in addition, differ in their low temperature tolerance. For the solubilization of organelles, a mild non-ionic detergent digitonin was used, which preserved and stabilized the supramolecular associations of membrane proteins. Using 1D BN-PAGE followed by ingel enzyme activity assay, it was shown that ATP synthase in all studied species was solubilized mainly as monomers Va and Vb, dimer Vb2, supercomplex IV1Va2, and minor subcomplex F1. In the course of the study, for the first time, differences in the detergent-stability of dimeric and monomeric forms of the enzyme between the studied species were revealed. It was found that the dimeric form in maize and the monomeric form in winter wheat were the most stable; while, pea ATP synthase had the highest activity. The relationship between the revealed features and the life strategy of the species is assumed and discussed.

Iron occupies one of the leading places among other elements in terms of content in soils and, having the ability to change valence and properties, diagnoses the typical and sub-type features of many soils, and most importantly, the direction of the soil formation process. Gypsum-bearing soils are formed on the deluvium of the Cambrian sedimentary rocks, in conditions of a hilly-flat relief, caused by water-erosion processes that have created surface dissections by numerous valleys and hollows. Gypsum-bearing soils are located on the elevated parts of the relief of the first floodplain river terraces, as well as in the lower parts of the relief and in river valleys. The climatic conditions of soil formation can be classified as arid. The amount of precipitation in the study area is much less than evaporation. The content, composition, and ratios of various forms of iron and the profile distribution of soils formed on gypsum-bearing red-colored Cambrian sedimentary rocks of the Upper Angara region were studied. For this, the composition of the soil cover in the landscape under study and the soilforming processes taking place in the soils were determined: brown arid calcareous soils are formed in the southern exposure of the slopes; in the northern exposure - chernozems, chernozems and meadow soils. An important morphoanalytical feature of soils is the presence of significant amounts of gypsum and carbonates in the profile. The leading soil-forming process in the landscape is the process of humus accumulation, which is clearly manifested in soils on the slopes of the left bank of the Zalari River. The group composition of iron was determined by analytical methods. The ratios of various iron groups, which are characteristic of landscape soils, and the regularities of the distribution of groups in soil profiles have been established. It was revealed that the degree of ferruginization of the soils of the left bank is in moderately low and very low limits; the degree of ferruginization of soils on the right bank is moderately low. The iron groups in the profiles are poorly differentiated. Silicate iron prevails over non-silicate. The significant predominance of silicate forms of iron over non-silicate forms indicates a low intensity and weak development of weathering processes. In all soils of the landscape, only traces of amorphous iron are determined. The mobility of iron in the soils of the landscape is practically absent, due to the insufficient amount of the amorphous form. In all landscape soils, the degree of oxidogenesis is very low. Crystallization of free iron oxides and hydroxides does not occur due to their absence.

The purpose of the study was to determine the role of COX-2 in the development and progression of molecular subtypes of invasive ductal breast cancer by comparing COX-2 expression level between different clinical and pathological prognostic parameters. Materials and methods. We studied 193 cases of invasive ductal breast cancer using comprehensive morphological, including immunohistochemical methods. General histological processing of samples was performed according to standard methods. Immunohistochemical studies for COX-2, ER, PR, c-erbB2, Ki-67 were performed according to the manufacturer's protocol with the control of samples. The grade of malignancy was determined according to the modified scheme of P. Scarff, H. Bloom and W. Richardson. COX-2 expression level was quantified using the Histoscore counting system in 86 cases. Immunoreactive index was defined as the product of positive cells and color intensity with a value from 0 to 12. The distribution of tumors with weak or strong expression of COX-2 was determined at the level of limit 6. Comparison of COX-2 expression at different clinical and pathological parameters was evaluated using the criterion Pearson χ2. For all types of analysis, differences were considered significant at p <0.05. Results and discussion. Immunohistochemical studies showed overexpression of COX-2 tumor cells in 53.49 [42.95-63.87] % of cases of invasive ductal breast cancer, mainly in premenopausal patients. Increased expression of COX-2 was determined in tumors with metastases to regional lymph nodes (53.66 66 [38.46-68.52] % - 63.64 (34.52-88.13] %), large size (73, 81 (59.63-85.82] % - 85.71 [52.74-99.97] %), running clinical stage (65.12 [54.78-74.78] %), with a low degree of differentiation G3 (80.95 [61.88-94.45] %), negative ER status and overexpression of HER-2/neu. Overexpression of COX-2 prevailed in patients under the age of 50 years (69.23 [54.04-82.54] %), in patients with triple-negative carcinoma phenotype (75.00 [54.26-91.01] %) and HER-2/neu + phenotype of invasive ductal breast cancer (73.68 [52.19-90.47] %). Conclusion. Overexpression of COX-2 has been associated with adverse prognosis factors such as young age, metastatic lymph node involvement, large tumor size, G3 poorly differentiation (high grade), negative ER status and HER-2/neu overexpression, and has been associated with an increased risk of recurrence of the disease, progression of the tumor process, increased risk of death. Overexpression of COX-2 may be a sign of an aggressive phenotype with metastatic potential, depend on hormonal status and be useful as a prognostic biomarker of invasive ductal breast cancer

The purpose of the study was to analyze the indicators of the lipid spectrum of blood in patients with rheumatoid arthritis individually and in combination with coronary heart disease. Materials and methods. 91 patients with rheumatoid arthritis were examined, which were divided into 2 subgroups – patients with rheumatoid arthritis without concomitant pathology of the cardiovascular system and patients with rheumatoid arthritis with coronary heart disease. The groups were matched in age and gender. The control group consisted of 31 patients with coronary heart disease. When entering the hospital a detailed clinical and biochemical examination with the determination of the pain scale, the number of painful and swollen joints, the duration of the morning stiffness, functional condition, lipid profile of blood was carried out. Results and discussion. In the study of the lipid spectrum of blood, a probable difference between the number of patients with signs of previously undiagnosed hyperlipidemia among patients with rheumatoid arthritis and rheumatoid arthritis with coronary heart disease was detected. At the same time, they observed dependence on the duration of the disease and the age of patients. The most significant changes were detected in the analysis of levels of total cholesterol, high density lipoprotein and low density lipoprotein, atherogenic coefficient. The indicators of blood triglycerides content had only a trend towards an increase in the subgroup of patients with combined nosology, which was not statistically confirmed. The incidence of hypercholesterolemia was 43.4% in the population of patients with rheumatoid arthritis, and 57.6% in patients with rheumatoid arthritis with coronary heart disease. Low density lipoprotein levels exceeded 3.0 mmol/l in 62.7% of rheumatoid arthritis patients and in 81.2% of patients with rheumatoid arthritis with coronary heart disease.

Abstrak

 

Karya sastra merupakan hasil kontemplasi terdalam sastrawan tentang hidup dan kehidupan.  Dengan ketajaman imajinasinya, potret kehidupan itu dielaborasi secara natural dalam roman, novel, puisi, dan lain sebagainya sehingga tersaji bagaikan gambaran nyata yang konkrit dan membius pembacanya. Belajar sastra secara baik dapat mencerdaskan pembaca. Segala hal ihwal pengalaman hidup dapat digali secara kritis dan kreatif. Dan hal itu merupakan misi utama pembelajaran sastra yang perlu dikembangkan guru sastra. Dengan keterbatasan kemampuan guru dan alokasi waktu perlu pemikiran bagi pengampu dan perancang kurikulum untuk menentukan visi dan misi arah pengajaran sastra secara terarah, terukur, dan benar. Dengan kurikulum 2013 yang disempurnakan, guru dan sekolah memiliki peluang yang cukup luas untuk berkreasi bagaimana meningkatkan etos pembelajaran sastra yang menarik, inovatif,  dan kondusif. Salah satu model yang dapat dikembangkan adalah dengan pendekatan prioritas, pragmatis, proses seleksi materi yang disesuaikan dengan kondisi kepentingan pembelajar, dan  tugas yang terukur, menyenangkan, serta terkontrol. Alternatif solusi yang dapat ditempuh agar pembelajaran sastra semakin baik dapat dimaksimalkan melalui; 1) Peran MGMP, 2) pemaksimalan penunjang lain, 3) akselerasi teknologi oleh guru sastra, 4) sekolah sebagai lahan sastra, 5) pembelajaran yang inovatif, 6) praktik bersastra ke teori bersastra, 7) tradisi rekreasional menggantikan tradisi pedantis, 8) memaksimalkan otonomi sekolah, 9) dan pertimbangan alokasi waktu.
