Morphological and molecular analyses reveal five new species of Hydnellum (Bankeraceae, Thelephorales) from the Changbai Mountains and Dabie Mountains, China Yonglan Tuo (22010993) Mycology Hydnellum new taxa phylogeny China This study describes five new species—H. aureomarginatum, H. coalescens, H. flavomarginatum, H. imbricatum, and H. jianense—collected from northeastern and central China, based on integrated morphological observations and phylogenetic analysis. Morphologically, H. aureomarginatum is characterized by a circular, depressed pileus that bears a golden-yellow zone on its inner margin, with the outermost edge of the pileus remaining white. H. coalescens is characterized by stipes of multiple basidiocarps that are fused or connate (forming a compound or interconnected basidiome) and a pileus covered with brown scales. H. flavomarginatum is characterized by a golden-yellow pileus margin and relatively large basidiospores. H. imbricatum is characterized by layered imbricate scales on the pileus and relatively long basidiospores. H. jianense is characterized by a plano-convex pileus covered with greyish-orange tomentum (which turns light brown when touched) and relatively small basidiospores. This study also compiles statistics on the main morphological characteristics, species distribution, and host information of the Hydnellum in China, deepening the understanding of the species diversity and distribution patterns of this genus. 2026-04-19T10:44:23Z Dataset Dataset 10.6084/m9.figshare.32038755.v2 https://figshare.com/articles/dataset/Morphological_and_molecular_analyses_reveal_five_new_species_of_Hydnellum_Bankeraceae_Thelephorales_from_the_Changbai_Mountains_and_Dabie_Mountains_China/32038755 CC BY 4.0 https://ndownloader.figshare.com/files/64088749 https://ndownloader.figshare.com/files/64088752 https://ndownloader.figshare.com/files/64088755 2 open access http://purl.org/coar/access_right/c_abf2

Distribution and community structure of riverine fish in two east-flowing rivers in Kenya Japhet Kaadzo Tembo (23808877) Charles Maina Kihia (23808880) Nzula Kivuva Kitaka (23808883) Gordon O’Brien (16979388) Emmanuel Mbaru (23808886) Catherine Kariuki (23808889) Cell Biology Evolutionary Biology Ecology Inorganic Chemistry Environmental Sciences not elsewhere classified assemblage structure Athi-Galana-Sabaki catch per unit effort Ramisi River This study investigated the distribution, composition and habitat associations of freshwater eels in the Athi–Galana–Sabaki (Athi) and Ramisi Rivers using fortnightly fyke-net sampling conducted between April 2021 and March 2022. A total of 304 eels were recorded, with the Ramisi contributing 76% of individuals and the Athi River 24%. The assemblage was dominated by Anguilla bengalensis (75% of all eels), followed by A. bicolor (12%), A. mossambica (8%) and A. marmorata (5%). A. bengalensis was widespread and most abundant upstream in both rivers, indicating broad habitat plasticity. In contrast, A. bicolor and A. mossambica were largely restricted to lower, more saline reaches, while A. marmorata occurred primarily upstream. Eel biomass exceeded that of non-eel fish at most sites and differed significantly among locations, with highest values recorded in the upper Ramisi River (ANOVA: F = 2.9, p = 0.04). A one-way analysis of similarity (ANOSIM) indicated significant spatial differences in eel distribution between rivers and reaches (Global R = 0.49, p < 0.05). Subsequent SIMPER analysis showed that these differences were primarily driven by variations in A. bengalensis (6%) and A. bicolor (1.12%). Multivariate analyses revealed significant spatial structuring of eel assemblages, with occurrence patterns strongly associated with conductivity, total dissolved solids, salinity, discharge, temperature, pH, and dissolved oxygen. These findings provide the first contemporary, reach-scale assessment of WIO eels in Kenyan rivers and highlight clear species-specific habitat associations along the river–estuary continuum. Conservation and fisheries management should prioritise maintaining longitudinal connectivity, protecting estuarine transition zones, sustaining water-quality gradients, and controlling invasive species to safeguard eel populations and their ecosystem functions. 2026-04-29T06:11:48Z Text Journal contribution 10.6084/m9.figshare.32121475.v1 https://figshare.com/articles/journal_contribution/Distribution_and_community_structure_of_riverine_fish_in_two_east-flowing_rivers_in_Kenya/32121475 CC BY 4.0 https://ndownloader.figshare.com/files/64088728 1 open access http://purl.org/coar/access_right/c_abf2

In this framework, the synthesis of disulfide-cross-linked polymer networks derived from epoxidized poly(ω-6-hexadecenlactone-co-ω-pentadecalactone) (P6HDL/PDL), a family of biobased, semicrystalline polyesters, is herein described. Cross-linking was achieved via reaction with 4,4′-dithiodibutyric acid (DTDB), introducing disulfide bonds into the polymer matrix. The network formation process was monitored through rheological time-sweep experiments and differential scanning calorimetry (DSC), while FTIR spectroscopy confirmed the completion of the epoxy–acid reaction. Rheological analysis revealed a composition-dependent increase in complex viscosity upon cross-linking at 180 °C, with the 50/50 copolymer achieving the highest network stiffness. Notably, copolymers with different compositions (P6HDL/PDL = 50/50 and 25/75) retained significant crystallinity after cross-linking. This coexistence of disulfide bonds and crystalline domains resulted in a composition-dependent viscoelastic response while maintaining a significant degree of structural order within the polymer network. The copolymers’ structure allowed tuning of cross-link density and crystallinity, offering a versatile platform for the design of renewable thermoset-like materials. The cleavage of disulfide bonds was achieved by treatment with 2-mercaptoethanol or 2-hydroxyethyl disulfide by UV light irradiation. These results demonstrated the feasibility of creating high-performance polymer networks from macrolactone-based polyesters using dynamic disulfide chemistry and laid the groundwork for the next generation of sustainable and possibly reprocessable plastics. 2026-04-29T00:00:00Z Text Journal contribution 10.1021/polymscitech.6c00021.s001 https://figshare.com/articles/journal_contribution/Semicrystalline_Polymacrolactone_Networks_via_Disulfide_Chemistry_Synthesis_Cross-Linking_and_Chemical_Degradation_Pathways/32121466 CC BY-NC 4.0 https://ndownloader.figshare.com/files/64088689 1 open access http://purl.org/coar/access_right/c_abf2

In recent years, numerous MOFs with tunable nanoporous architectures have been developed as promising candidates for natural gas and hydrogen storage. To enhance the hydrogen storage capacity of MOFs while reducing the overall cost, this study integrates MOFs with cost-effective materials that provide additional active sites for hydrogen adsorption. Here, we report the development of a composite consisting of graphene oxide (GO) and Ni-based MOF-74 (Ni-MOF-74), which combines the high surface area and functional groups of GO with the extensive porosity and open metal sites of the MOF. The Ni-MOF-74/GO composite was synthesized via an in situ growth method and extensively characterized by using transmission electron microscopy, scanning electron microscopy, Fourier transform infrared spectroscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy, and Brunauer–Emmett–Teller surface area analysis to confirm its integrated structure and porosity. Hydrogen adsorption isotherms at 77 K and up to 1 bar reveal that the Ni-MOF-74/GO composite exhibits a significantly higher H2 uptake capacity than either pristine GO or Ni-MOF-74 alone. Notably, the composite with an optimal GO loading (10 wt %) achieves the highest storage enhancement, demonstrating a synergistic effect between GO and the MOF in maximizing hydrogen adsorption. Density functional theory (DFT) and Monte Carlo simulations provided molecular-level insights, indicating that H2 molecules occupy both the microporous channels of Ni-MOF-74 and the GO surface, particularly at the Ni-MOF-74/GO interfacial regions. This hybrid framework exhibits a slightly stronger hydrogen adsorption energy (−3.34 kcal/mol) compared to Ni-MOF-74 alone (−3.25 kcal/mol), with minimal structural distortion upon H2 uptake. 2026-04-29T00:00:00Z Text Journal contribution 10.1021/acs.langmuir.6c01098.s001 https://figshare.com/articles/journal_contribution/Enhanced_Hydrogen_Storage_in_Metal_Organic_Framework_Graphene_Oxide_Composites_Experimental_Characterization_and_Molecular_Simulations/32121463 CC BY-NC 4.0 https://ndownloader.figshare.com/files/64088662 1 open access http://purl.org/coar/access_right/c_abf2

Here we introduce StoL, a diffusion-model-based framework that enables rapid and knowledge-free generation of large molecular structures from small-molecule data. Remarkably, StoL assembles molecules in a LEGO-style fashion from scratch without seeing the target molecules or any structures of comparable size during training. Given an SMILES input, it decomposes the molecule into chemically valid fragments, generates their 3D structures with a diffusion model trained on small molecules, and assembles them into diverse conformations. This fragment-based strategy eliminates the need for large-molecule training data while maintaining high scalability and transferability. By embedding chemical principles into key steps, StoL ensures faster convergence, chemically rational structures, and broad configurational coverage, as confirmed against DFT calculations. 2026-04-29T00:00:00Z Text Journal contribution 10.1021/acs.jpclett.5c04019.s001 https://figshare.com/articles/journal_contribution/Chemistry-Enhanced_Diffusion-Based_Framework_for_Small-to-Large_Molecular_Conformation_Generation/32121460 CC BY-NC 4.0 https://ndownloader.figshare.com/files/64088659 1 open access http://purl.org/coar/access_right/c_abf2

Scalable All Nanotube Carbon Nanotube–Boron Nitride Nanotube–Carbon Nanotube Supercapacitors for Enhanced Structural Energy Storage BJ Mapleback (18566350) VH Dao (23808850) AN Rider (18566353) Patrick Howlett (13088661) Chemical sciences Physical chemistry Engineering Chemical engineering Materials engineering boron nitride nanotubes carbon nanotubes Electrochemistry ionic liquids Materials Science Materials Science, Multidisciplinary Physical Sciences Science & Technology supercapacitors Technology Composite structural supercapacitors (SSCs) seek to offer improved size, weight, and power energy storage to mobile devices or transportation vehicles. This technology, similar to the development cycle of high‐performance batteries, requires significant materials development tailored to the supercapacitors requirements. Several electrode materials have been developed which offer good energy and power performance, but are limited in their effectiveness due to the lack of an advanced separator material suitable for high‐performance composite materials processing. Currently, glass fiber cloths are the only feasible separator material for SSCs. The present research effort examines an alternative to separator materials. Boron nitride nanotube (BNNT) films have been deposited onto a single side of carbon nanotube (CNT) mat electrodes using vacuum filtration. Thin and uniform BNNT films show good coverage, but may exhibit thickness variations due to the flow properties of the underlying CNT mat. BNNT coverage and mechanical robustness are improved at significantly reduced thicknesses by decreasing the amount of BNNT and adding long‐chain polymer binders. Careful selection of polymers and ionic liquid electrolyte enables production of reliable, high‐rate performance supercapacitors with specific energy and power of 11.5 Wh kg − 1 at 0.137 kW kg − 1 and 7.87 Wh kg − 1 at 2.69 kW kg − 1 with higher charge–discharge rates. These CNT–BNNT combined electrode and separator components were integrated into a high‐performance fiber‐reinforced polymer composite and cured using industrial autoclave‐cure techniques. The SSC provided excellent electrochemical performance with specific energy and power of 12.8 Wh kg − 1 at 0.0985 kW kg − 1 and retained 3.57 Wh kg −1 at 1.31 kW kg −1 at higher charge–discharge rates, normalizing the combined electrode mass of the CNT–BNNT cathode and anode. The device also shows reliable long‐term performance with 70% capacity retention after 5000 charge–discharge cycles from 0 to 3.3 V at high rates of 0.5 A g −1 . 2026-04-01T00:00:00Z Text Journal contribution 10.26187/deakin.32121265 https://figshare.com/articles/journal_contribution/Scalable_All_Nanotube_Carbon_Nanotube_Boron_Nitride_Nanotube_Carbon_Nanotube_Supercapacitors_for_Enhanced_Structural_Energy_Storage/32121265 All Rights Reserved https://ndownloader.figshare.com/files/64088398 1 restricted access http://purl.org/coar/access_right/c_16ec

Simultaneous Cross-Linking Olefin Polymerization Technology for Heterophasic Copolymerization of Propylene toward High-Rubber-Content TPO: Critical Role of the Concentration of Nonconjugated α,ω-Diene Cross-Linker Yiming Wang (163598) Jin-Yong Dong (2257189) Biophysics Biochemistry Cell Biology Molecular Biology Evolutionary Biology Cancer Environmental Sciences not elsewhere classified Biological Sciences not elsewhere classified Chemical Sciences not elsewhere classified Physical Sciences not elsewhere classified work clearly identifies performance polyolefin elastomers optimal operational window linker utilizing 1 enabling synergistic increases achieving integrated control universal triconcentration framework topological evolution mechanisms linear chain structures propylene toward high model nonconjugated α low dd loadings linking olefin polymerization gel network formation w < sub predictive framework phase evolution critical concentration chain relaxation chain construction chain branching c </ lcb (< study elucidates simultaneous cross results indicate producing high parameters establish investigative linchpin heterophasic copolymerization critical role content tpo construction mechanism branched architectures Utilizing 1,9-decadiene (DD) as a model nonconjugated α,ω-diene, high-rubber-content TPO was prepared through simultaneous cross-linking olefin polymerization (SCOP) based on Ziegler–Natta catalysts. Taking the counterintuitive particle adhesion observed at low DD loadings as the investigative linchpin, this study elucidates the long-chain branching (LCB) construction mechanism in SCOP processes and proposes a universal triconcentration framework: the critical concentration for LCB (Ccritical), the induction concentration (Cinduction), and the gelation concentration (Cgel). These parameters establish a comprehensive topological evolution framework describing the transition from linear chain structures to branched architectures and eventually to gel network formation, achieving integrated control and close correlation across three scales: chain construction, chain relaxation, and phase evolution. The results indicate that below Ccritical, chain transfer dominates, leading to reduced molecular weight (Mw). Beyond Cinduction, effective intermolecular cross-linking is triggered, enabling synergistic increases in Mw and long-chain branching density (DLCB). Upon Cgel, a gel network is formed. This work clearly identifies the optimal operational window for producing high-rubber-content TPO via SCOP technology as lying between Cinduction and Cgel, providing fundamental insights into topological evolution mechanisms and establishing a predictive framework that may guide future process design for high-performance polyolefin elastomers. 2026-04-29T00:00:00Z Text Journal contribution 10.1021/acs.iecr.6c00951.s001 https://figshare.com/articles/journal_contribution/Simultaneous_Cross-Linking_Olefin_Polymerization_Technology_for_Heterophasic_Copolymerization_of_Propylene_toward_High-Rubber-Content_TPO_Critical_Role_of_the_Concentration_of_Nonconjugated_-Diene_Cross-Linker/32121457 CC BY-NC 4.0 https://ndownloader.figshare.com/files/64088632 1 open access http://purl.org/coar/access_right/c_abf2 eyJtZXRhZGF0YVByZWZpeCI6ICJxZGMiLCAidmVyYiI6ICJMaXN0UmVjb3JkcyIsICJvYWlfaGFuZGxlciI6IHRydWUsICJwYWdlIjogMiwgInhDdXJzb3IiOiAiZXlKaGJHY2lPaUpJVXpVeE1pSjkuSWxzeE56YzNORFF5T0RNME1EQXdMQ0F6TWpFeU1UUTFOMTBpLjdJY1NYd3h1amFKVFBzM0l6Ni1HOUZwMi1oVHBHOTFUZFhHSVNqZl9ULURJNmJyUGpKcFJDVDVRM1dXU1RUdjB0TnQ2RDd5WUF6V0NLYjF1eFRWVWpRIiwgImV4cGlyYXRpb24iOiAiMjAyNi0wNC0yOSAwNzoxNTo0MCJ9
