Members of Cryptosporella are well-known as common endophytes, and occasionally, as pathogens on a narrow range of hosts in Betulaceae, Tiliaceae and Ulmaceae. Two fresh specimens associated with canker and dieback of Betula platyphylla were made in Beijing, China in 2015. Morphological and multi-gene, combined, phylogenetic analyses (ITS, tef1-alpha and beta-tub) support these speciemens as a distinct and new species of Cryptosporella, from a unique host, Betula platyphylla. Cryptosporella platyphylla sp. nov. is introduced with an illustrated account and differs from similar species in its host association and multigene phylogeny.

Druzhinina, Feng Cai, Xinlei Fan, Laura Selbmann, Claudia Coleine, Rafael F. Castaneda-Ruiz, Martin Kukwa, Adam Flakus, Patricia Oliveira Fiuza, Paul M. Kirk, Kunhiraman C. Rajesh Kumar, Ilesha S.

Summary: Asexually reproducing fungi play significant roles in ecosystems and have implications for plant and animal health, food production, biotechnology, and medicine. However, the diversity and extent of asexually reproducing taxa are not well-known. Recent reports suggest that there may be more asexual fungi than sexually-reproducing ones. Evaluating the diversity of different types of fungi, such as speciose and pleomorphic taxa, as well as those from less studied life modes and biodiversity-rich areas, is necessary to obtain more reliable estimates.

Fungal Richness of Cytospora Species Associated with Willow Canker Disease in China

Lu Lin, Meng Pan, Chengming Tian, Xinlei Fan

Summary: Eight species of Cytospora were discovered on Salix in China, including two newly identified species. These species were confirmed as pathogens of willow canker disease, and their mycelial growth rates were influenced by optimal temperatures and pH values, as well as fructose and maltose. The species richness of Cytospora showed a significant positive correlation with dry and wet areas.

Re-evaluation of the Fungal Diversity and Pathogenicity of Cytospora Species from Populus in China

Lu Lin, Meng Pan, Jadson D. P. Bezerra, Chengming Tian, Xinlei Fan

Summary: Poplar is widely cultivated in China due to its adaptability, fast growth, and easy reproduction. However, it is threatened by canker disease caused by Cytospora species. This study identified six Cytospora species isolated from Populus in six provinces in China, and four of them were confirmed as pathogens. The study also investigated the optimal growth conditions and carbon sources for these species.

Wave attenuation of a multi-span continuous beam with variable cross sections

Xiaochen Mao, Liufei Zhang, Xinlei Fan

Summary: This paper investigates the vibration band-gaps of a non-uniform beam with periodically continuous variable cross sections and hinged supports. The governing equation of the beam is obtained using the spectral element method, and the frequency responses under external excitation are presented. The accuracy and efficiency of the spectral element method are validated, and the advantages of the proposed beam are discussed. The effects of structural and material parameters on the band-gap properties, such as the height curve, the disordered vibration absorbers, and the material attributes, are explored. Additionally, the coupling effects of the local resonance band-gaps and the Bragg scattering band-gaps are investigated for potential use in band-gap structure design.

Preparation of robust fully encapsulated structural color fabrics and their application to display

Shuai Li, Lixia Jia, Linlin Wang, Pengchao Li, Xinlei Fan

Summary: Building photonic crystals on flexible textiles can create structural color fabrics, but there are challenges with fabric properties, stability, and application scenarios. This study successfully immobilized polystyrene photonic crystals on cotton fabric, providing bright colors and high mechanical stability. The fabric could also be used for adhesive tapes with good adhesive properties to different materials.

A novel magnetic manganese oxide halloysite composite by one-pot synthesis for the removal of methylene blue from aqueous solution

Suhong Zhang, Xinlei Fan, Jing Xue

Summary: In this study, a magnetic manganese oxide halloysite composite was prepared and characterized. The composite exhibited enhanced methylene blue removal through synergistic adsorption capacity and Fenton-like degradation. It can be separated and regenerated using an external magnetic field. The stable removal performance in multiple cycles was also demonstrated.

Multi bandgaps design of sandwich metamaterial plate with embedded membrane-type resonators

Jinqiang Li, Yao Zhang, Xinlei Fan, Fengming Li

Summary: This study proposes a metamaterial plate with multi bandgaps for vibration suppression by integrating membrane-mass structures that can be used as locally resonant metastructure into a honeycomb sandwich structure. The mode shapes of the membrane-mass resonator and face plate in a unit cell are analyzed to investigate the formation mechanisms of the locally resonant bandgaps. An improved multi bandgaps structure is designed and discussed. Experimental measurements show that the proposed metamaterial exhibits excellent vibration suppression performance.
