Cnephasia kenneli Obraztsov. A 1956
No full text14. Cnephasia kenneli Obraztsov, 1956 Material examined. Zanjân Prov.: 12 ♂♂, 1 ♀, Sohrein Vlg. to Dagâhi Vlg. Rd., 6 km to Dagâhi Vlg., N 36˚53΄03.8̎ E 048˚28΄08.3̎, 4084 m, 4.vi.2012, Âlipanâh, Falsafi leg. (GS: HA-2404, HA-2081, HA-2086, HA-2388, HA-2394, HA-2396, HA-2397). Diagnosis. Among identified females of the longana species-group, C. kenneli is most similar to C. amseli (D. Lucas, 1942) in the female genitalia (see Razowski 1965: 270, 274; Razowski 2002: 91). In both species the lateral parts of the sterigma are triangular and narrowed distally, with the posterior margins concave medially. In both species the ostium bursae is rounded and antrum is nearly cup-shaped and slightly sclerotized. The relative length of the ductus bursae to the corpus bursae and the size and shape of signum in both species are the same. However, in C. amseli there is a relatively long inner sclerotization at the posterior half of the ductus bursae, whereas in C. kenneli there is a twisted sclerotized structure inside the ductus bursae which is located at its anterior half (Figs. 8A, C). Moreover, in C. kenneli the papillae anales are wider than in C. amseli. The male genitalia of C. amseli are still unknown; on the other hand, the forewing pattern of the latter species is different from that of the C. kenneli. As stated by Razowski (1965), C. kenneli is superficially similar to C. dispersana; however, the two can be distinguished by their genitalia. Description of the female. Head (Fig. 6G): Scales mostly smooth, elongate, white; white to creamy-light brown on frons; labial palpus sinuate with third segment pointed anterad, creamy-white irregularly admixed with light brown to yellowish-brown scales dorso-laterally, except creamy-white first segment, with length 1.83 times the horizontal diameter of compound eye, second segment longest with slightly elongate and erect scales dorso-apically; antennae nearly white dorsally at one-third, the remaining ringed with white and creamy-light brown scales, sensilla shorter than the male. Thorax: Creamy-white admixed with light brown scales, with a pair group of erect creamy-white scales admixed with dark brown scales posteriorly. Female slightly larger than male, with forewing length 11.4 mm (n = 1). Forewing shape and pattern similar in males and females (Figs. 6A – D), slightly broadened distally, with nearly straight costa finely arched outwards basally, rounded apex, obliquely rounded termen; upperside grayish-cream, with a few scattered brown to pale brown scales at dorsum margin and distal end, cilia creamy-white with a gray brown dividing transverse line; underside light brown except narrow creamy costal margin. Hindwing (Figs. 6A, B) upperside darker than the forewing, grayish-light brown, cilia creamy-white with a gray brown dividing transverse line; underside paler than the forewing, cream. Abdomen: Grayish-cream, with elongate yellowish-cream scales dorsally. Female genitalia (Figs. 8 A–C) with papillae anales moderate, medially broad, apically rounded; ostium bursae circular, heavily sclerotized ventrolaterally; apophyses posteriores longer than apophyses anteriores, 1.3 times length of apophyses anteriores, both gradually narrowed distally; lateral parts of sterigma broad, gradually tapering laterally, slightly concave medially on posterior margin, with several long setae mostly at median part; antrum cup-shaped, weakly sclerotized (Figs. 8A, B); ductus bursae narrow, with a twisted, irregular sclerotized structure at anterior half (Figs. 8A, C); ductus seminalis arising from anterior end of ductus bursae, slightly behind connection with corpus bursae (Figs. 8A, C); corpus bursae large, pear-shaped, signum moderate. Distribution. Jordan (Jordan Valley), Asia Minor (Eibés, Malatya), Syria?, Kulscha? (Kennel 1901, 1910, Obraztsov 1956, Razowski 1965). Remarks. Cnephasia obsoletana was described by Kennel (1901) based on a single male specimen from the Jordan Valley, Jordan. Obraztsov (1956) recognized that the name was preoccupied and proposed the replacement name Cnephasia kenneli. In 1910 Kennel described Tortrix obsoletana from a male specimen from Eibés, Malatya in southeastern and eastern Asia Minor. According to Razowski (1965), the latter is considered a synonym of C. kenneli. The female has remained undescribed. During the present study, a female collected at the same locality as C. kenneli males was discovered in the HMIM, both sexes collected by the author in Zanjan Province. Because the female is superficially similar to the males of C. kenneli, the two sexes are considered conspecific. As revealed in this study, there is considerable intra-specific variation in the male genitalia of C. kenneli, especially in the shape of the valva. As figured by Razowski (1965: 264, 265), the valva of C. kenneli is pointed, while in examined males the apical part of the valva is more rounded (Figs. 7A, E, H, I) or obliquely rounded (Fig. 7J). In some specimens, the valva is curved internally behind the mid-ventral part (Fig. 7H). Also, the width of the valva in examined males is slightly less than that figured by Razowski (1965). Some of this variation may be an artefact of slide mounting. During the preparation of male genitalia, the lower margin of the apical part of the valva usually turns back and thereby the apical part seems narrower than it actually is. Additionally, the free termination of the sacculus is normally turned more or less upward on the disc of the valva (Figs. 7A, D, I, J), but sometimes it may turn downward depending on slide preparation (Figs. 7E, F, H). Cnephasia kenneli has rather moderate, simple socii (see Razowski 1965: 264, 265), however, in the examined males the socii are relatively wide, 1.6 times the width of the uncus at its narrowest point (n = 5). Furthermore, in most of the examined males, the free termination of the socii are nearly straight or very slightly depressed medially, but they often appear bilobed, i.e., a slightly longer apically rounded lateral lobe and a somewhat shorter medial one (Figs. 7A, C, E). The terminal plate of the gnathos in the examined males is wedge-like (Figs. 7A, C, E), whereas it appears to be trapezoidal in figures presented by Razowski (1965: 264). The density of spines at the free termination of the sacculus also varies among the specimens (Figs. 7A, D, E, F, H–J). Comments. Although males and females are similar superficially, a few differences (except the shorter length of sensilla of female antennae) were observed between them. The female is somewhat larger than male; i.e., forewing length 9.7 – 11.7 mm (= 10.73 mm ± 0.52, n = 12) in males, 11.4 mm (n = 1) in the female. Moreover, the female has a slightly smaller compound eye (Fig. 6G) compared to that of males (Figs. 6E, F). Also, the dorsal surface of the male antennae is covered with white scales only basally or ringed throughout, whereas in female the white scales extended to the proximal one-third of the antennae. In both male and female, the number of scales in darker rings of the antennae is less than those of the white rings.Published as part of Alipanah, Helen, 2019, An overview of the tribe Cnephasiini (Lepidoptera: Tortricidae: Tortricinae) of Iran with description of a new species, pp. 501-521 in Zootaxa 4661 (3) on pages 508-514, DOI: 10.11646/zootaxa.4661.3.5, http://zenodo.org/record/338136

Sociologist 4.0: Challenges and risks for the professional sociological education
No full textThe Russian system of the professional sociological education, if we date its institutionalization to the creation of the first sociological faculties in the USSR in 1989, has functioned for more than thirty years. However, in the coming years, this education will have the most difficult period in its development due to the transition to a new two-level model of higher education and to the adoption of the Federal State Educational Standard of the 4th generation (FSES 4). The implementation of these plans creates certain challenges: 1) sociological training would lose the status of an independent enlarged group of specialties (EGS) and would be included into the political sciences EGS; 2) the suggested program of joint training of sociologists with representatives of political sciences in the first two years of study would reduce the study time for mastering sociological academic disciplines; 3) there are certain contradictions between the basic and specialized levels of higher education due to the suggested expanded opportunities for basic-level graduates to enroll in graduate school. Moreover, such issues as the target numbers for the EGS, mechanisms for their distribution between areas of training and possibility of simultaneous training in ‘related’ specialties have not been resolved. These challenges create risks for sociology of maintaining its status of a specialty, and, ultimately, a threat to its independence and identity. The author suggests some measures to develop the professional sociological education and to maintain its status under the current reform of the national higher education system, which is primarily the restoration of the sociological EGS in the List of Areas of Training in Higher Education, which would make the new FSES 4 focus on the related areas of training and improve the quality of sociological education
On localizations of quasi-simple groups with given countable center
No full textA group homomorphism i:H→G is a localization of H, if for every homomorphism φ:H→G there exists a unique endomorphism ψ:G→G such that iψ=φ (maps are acting on the right). Göbel and Trlifaj asked in [18, Problem 30.4(4), p. 831] which abelian groups are centers of localizations of simple groups. Approaching this question we show that every countable abelian group is indeed the center of some localization of a quasi-simple group, i.e., a central extension of a simple group. The proof uses Obraztsov and Ol'shanskii's construction of infinite simple groups with a special subgroup lattice and also extensions of results on localizations of finite simple groups by the second author and Scherer, Thévenaz and Viruel
Supramolecular donor - acceptor hybrid of electropolymerized zinc porphyrin with axially coordinated fullerene: Formation, characterization, and photoelectrochemical properties
No full textThis is an open access article under the CC BY license.Photoelectrochemical behavior of self-assembled C 6o via axial coordination to an electrochemically polymerized zinc porphyrin film was systematically investigated to unravel the importance of the coordinated fullerene in improving the photocurrent and photovoltage generation of the resulting donor-acceptor dyad. For this, tetrakis(4-(N, N-diphenylamino)-phenyl) porphyrinato-zinc(II), (Ph 2N) 4ZnP, bearing electropolymerizable triph-enylamine peripheral substituents was first electropolymerized to form a film on the electrode surface. The resulting formation of the electrochemically active and dense film was confirmed by using an electrochemical quartz crystal microbalance (EQCM) and by atomic force microscopy imaging. The optical absorption and emission studies revealed the characteristic absorption and emission bands of zinc porphyrin that suggested preservation of the π-electron system of the porphyrin monomer in the polymer. Further, the fullerene, derivatized with an axially coordinating imidazole ligand, was allowed to self-assemble via axial coordination to the zinc center of the (Ph 2N) 4ZnP polymer film. The simultaneously performed piezoelectric microgravimetry and cyclic voltammetry studies using EQCM allowed us to prove this coordination and to evaluate the redox potential of the donor, (Ph 2N) 4ZnP, and acceptor, C 60, moiety. The fluorescence emission results, along with the free energy calculations, suggested the occurrence of vectorial photoinduced electron transfer from the singlet-excited ZnP in the polymer to the axially coordinated fullerene moiety. Systematic photoelectrochemical studies revealed cathodic photocurrent generation, a result unlike most of the dye-sensitized photoelectrochemical cells reported in the literature. Moreover, the coordinated fullerene to the zinc porphyrin film improved the photocurrent and photovoltage generation of the photoelectrochemical cell. An incident photon-to-current conversion efficiency (IPCE) of nearly 2% at the Soret region of maximum absorption was determined for the [(Ph 2N) 4ZnP polymer] - fullerene hybrid film. © 2009 American Chemical Society., (0804015

Graphene acid for lithium-ion batteries - Carboxylation boosts storage capacity in graphene
No full textEnvironmentally sustainable, low-cost, flexible, and lightweight energy storage technologies require advancement in materials design in order to obtain more efficient organic metal-ion batteries. Synthetically tailored organic molecules, which react reversibly with lithium, may address the need for cost-effective and eco-friendly anodes used for organic/lithium battery technologies. Among them, carboxylic group-bearing molecules act as high-energy content anodes. Although organic molecules offer rich chemistry, allowing a high content of carboxyl groups to be installed on aromatic rings, they suffer from low conductivity and leakage to the electrolytes, which restricts their actual capacity, the charging/discharging rate, and eventually their application potential. Here, a densely carboxylated but conducting graphene derivative (graphene acid (GA)) is designed to circumvent these critical limitations, enabling effective operation without compromising the mechanical or chemical stability of the electrode. Experiments including operando Raman measurements and theoretical calculations reveal the excellent charge transport, redox activity, and lithium intercalation properties of the GA anode at the single-layer level, outperforming all reported organic anodes, including commercial monolayer graphene and graphene nanoplatelets. The practical capacity and rate capability of 800 mAh g−1 at 0.05 A g−1 and 174 mAh g−1 at 2.0 A g−1 demonstrate the true potential of GA anodes in advanced lithium-ion batteries
Harnessing enhanced lithium-ion storage in self-assembled organic nanowires for batteries and metal-ion supercapacitors
No full textOrganic materials have emerged as highly efficient electrodes for electrochemical energy storage, offering sustainable solutions independent from non-renewable resources. In this study, we showcase that mesoscale engineering can dramatically transform the electrochemical features of a molecular organic carboxylic anode. Through a sustainable, energy-efficient and environmentally benign self-assembly strategy, we developed a network of organic nanowires formed during water evaporation directly on the copper current collector, circumventing the need for harmful solvents, typically employed in such processes. The organic nanowire anode delivers high capacity and rate, reaching 1888 mA h g−1 at 0.1 A g−1 and maintaining 508 mA h g−1 at a specific current of 10 A g−1. Moreover, it exhibits superior thermal management during lithiation in comparison to graphite and other organic anodes. Comprehensive electrochemical evaluations and theoretical calculations reveal rapid charge transport mechanisms, with lithium diffusivity rates reaching 5 × 10−9 cm2 s−1, facilitating efficient and rapid interactions with 24 lithium atoms per molecule. Integrated as the negative electrode in a lithium-ion capacitor, paired with a commercially available porous carbon, the cell delivers a specific energy of 156 W h kg−1 at a specific power of 0.34 kW kg−1 and 60.2 W h kg−1 at 19.4 kW kg−1, establishing a benchmark among state-of-the-art systems in the field. These results underscore the critical role of supramolecular organization for optimizing the performance of organic electrode materials for practical and sustainable energy storage technologies
