Strongly coupled Nafion molecules and ordered porous CdS networks for enhanced visible-light photoelectrochemical hydrogen evolution
No full textStrongly coupled Nafion molecules and ordered porous CdS networks are fabricated for visible-light photoelectrochemical (PEC) hydrogen evolution. The Nafion layer coating shifts the band position of CdS upward and accelerates charge transfer in the photoelectrode/electrolyte interface. It is highly expected that the strong coupling effect between organic and inorganic materials will provide new routes to advance PEC water splitting.Xue-Li Zheng, Ji-Peng Song, Tao Ling, Zhen Peng Hu, Peng-Fei Yin, Kenneth Davey, Xi-Wen Du and Shi-Zhang Qia
Fire Dragon Feminism: A Breathe in
No full textThis workshop invites participants to engage in creative story-telling using textiles to share their migration journey. Developed by visual artist, Yanti Peng, participants will receive a guide to create their textile collage. Dr Quah Ee Ling, a gender and sexuality, migration researcher, will guide participants through a series of reflection questions on the celebrations and challenges of their migration trajectoires
Pseudoseliza Peng, Wang & Zhang, 2010, gen. n.
No full textPseudoseliza gen. n. Type species. Pseudoseliza crassiprocessa sp. n. Medium-sized planthoppers. Head narrower than pronotum. Vertex wider than long, anterior margin slightly pointed in dorsal view. Frons broader than long, with median carina extending onto vertex. Pronotum slightly shorter than head, with median carina; postocular eminence small, conical. Tegmen about 2.5 times longer than wide, costal membrane slightly broader than costal cell; costal margin truncate, not sinuate before apex, apical margin convex with two submarginal lines of crossveins; three longitudinal veins arising from basal cell (Sc+R, M, Cu); vein Sc crossing elevated bulla. Metatibial lateral spines 2. Etymology. The name is derived from the Greek prefix “ pseudo ” meaning “false”, in combination with the genus Seliza, which means this new genus resembles Seliza. The gender is feminine. Remarks: This new genus is placed into the tribe Selizini by the following combination of characteristics: all fawn-colored and medium in size; tegmen elongated, about 2.5 times as long as broad, claval vein at the base strongly elevated; postocular eminence conical (Figs. 1–2); antennal segment I very short, ring-like, segment II tubular. The new genus is close to Paraflatoptera and Meulona, but differs from them mainly by: head slightly pointed in dorsal view; two metatibial lateral spines. It is also very similar to Seliza by the shape of tegmen and the number of metatibial lateral spines, but can be distinguished by: frons with a median carina extending onto vertex and projection medially in lateral view (Figs. 1–2); tegmen with 2 subapical lines and costal margin not sinuate before costal angle (Fig. 4); male abdominal segment IX narrowed in lateral view, genital style not triangular (Fig. 6).Published as part of Peng, Ling-Fei, Wang, Ying-Lun & Zhang, Ya-Lin, 2010, A new genus and one new species of the Tribe Selizini (Hemiptera: Fulgoromorpha: Flatidae) from China, with a checklist of the tribe from the Oriental Region, pp. 46-52 in Zootaxa 2420 on pages 48-49, DOI: 10.5281/zenodo.19445
Malaxis henanensis D. H. Peng & K. Yang 2023, sp. nov.
No full textMalaxis henanensis D.H.Peng & K.Yang, sp. nov. (Figs 1, 2) Type:— CHINA. Henan Province: Neixiang County, 1722 m, Baotianman National Nature Reserve, 26 Jul 2021, Peng M001 (FAFU). The new species differs from M. malipoensis in height, inflorescence structure, number of leaves and flowers, colour of flower bracts, long-ovate sepals, longer petals and ovoid, apically narrow lip (Table 1). Terrestrial, erect herbs, 9–25 cm. Leaves usually 2, one larger, base contracted into petiole, clasping, ovate to long ovoid, apex attenuate, 5.0–12.0 × 2.5–5.0 cm. Inflorescence arising from leaf axils, erect, 12–22 cm long, 3.0– 3.5 mm in diameter; racemes 10–15 cm long, 40–80 flowers; floral bracts lanceolate, 1.5–2.0 mm long, yellowish green; pedicel and ovary 3.0– 3.5 mm long, pedicels twisted in a right-handed spiral; fully open flowers 3 mm in diameter, yellowish green; sepals subequal, long-ovate, 1.5–1.8 × 0.7–1.0 mm; petals linear, 1.3–1.5 × 0.2–0.3 mm; lip uppermost (non-resupinate), ovoid, apically narrow, 1.3–1.5 × 0.9–1.2 mm; disk oblate, slightly concave in the middle, both margins hypertrophic and warty, with a short auricles on both sides of the base; column 0.6 mm long; pollinia 4, in 2 pairs, waxy. Phenology:— Flowering July and August. Distribution and ecology:— Known only from Neixiang County, Henan Province, growing in humus-rich soil. Etymology:— Named after Henan Province. Conservation:— Although we investigated areas in the southern and western hilly regions of Henan that would be suitable for this orchid, we did not find plants. The greatest threat to the survival of the new species in the area is human activity and being eaten by wild boars. Notes:— Most Malaxis species have small greenish flowers (Jermakowicz et al. 2022), which also applies to M. henanensis and M. moliponesis (Table 1).Published as part of Shi, Xiao-Ling, Kang, Yang, Liu, Yu-Ying, Tu, Song, Peng, Hong-Jun, Liu, Zhong-Jian & Peng, Dong-Hui, 2023, Malaxis henanensis (Orchidaceae, Malaxideae), a new species from China, pp. 293-295 in Phytotaxa 589 (3) on pages 293-295, DOI: 10.11646/phytotaxa.589.3.9, http://zenodo.org/record/777703
