Tuning excited state electronic structure and charge transport in covalent organic frameworks for enhanced photocatalytic performance
Article describes how covalent organic frameworks (COFs) represent an emerging class of organic photocatalysts. The authors use reticular chemistry to construct a family of isoreticular crystalline hydrazide-based COF photocatalysts, with the optoelectronic properties and local pore characteristics of the COFs modulated using different linkers.

Linking random forest and auxiliary factors for extracting the major economic forests in the mountainous areas of southwestern Yunnan Province, China
Article describes how forests are generally extracted from remotely sensed images based on the spectral features, ignoring other important auxiliary information, and the techniques of precise extraction need to be further improved. By using the Sentinel–2 image and auxiliary factors (AFs) including site conditions (SCs) and vegetation indices (VIs), the random forest model with AFs (RF–AFs) was adopted for the extraction of the economic forests in Lancang County, which is a mountainous area with rich biodiversity and is witnessing rapid development of economic forests in Yunnan province of China.

Automated Approach to In Vitro Image-Guided Photothermal Therapy with Top-Down and Bottom-Up-Synthesized Graphene Quantum Dots
Article discusses how, based on recent studies, graphene quantum dots (GQDs) are expected to possess advantageous photothermal properties and facilitate fluorescence image-tracking in the visible and near-infrared (NIR), while surpassing other graphene-based materials in their biocompatibility. The combination of the photothermal and imaging modalities tested in vitro makes the GQDs developed in this work prospective agents for cancer theragnostics.

Spatially confined protein assembly in hierarchical mesoporous metal-organic framework
Article discusses how the immobilization of biomolecules into porous materials could lead to significantly enhanced performance in terms of stability towards harsh reaction conditions and easier separation for their reuse. To gain insights into the spatial arrangement of biomolecules within the nanopores, the authors used in situ small-angle neutron scattering (SANS) to probe deuterated green fluorescent protein (d-GFP) entrapped in a mesoporous MOF.

Insights into the Bioinformatics and Transcriptional Analysis of the Elongator Complexes (ELPs) Gene Family of Wheat: TaELPs Contribute to Wheat Abiotic Stress Tolerance and Leaf Senescence
Article states that elongator complexes (ELPs) are the protein complexes that promote transcription through histone acetylation in eukaryotic cells and interact with elongating RNA polymerase II. ELPs’ role in plant growth and development, signal transduction, and response to biotic and abiotic stresses have been confirmed in model plants, but the functions of the wheat ELP genes are not well documented. The present study identified 18 members of the ELPs from the wheat genome with a homology search.

High-Throughput Investigation of Multiscale Deformation Mechanism in Additively Manufactured Ni Superalloy
Article discusses how, in this paper, Inconel 718 (IN718) superalloy was processed by laser powder-bed fusion additive manufacturing (L-PBFAM), followed by heat treatment. Evidence of extensive deformation of twin networks and dislocation cells was revealed by transmission electron microscopy of the deformed region under the nanoindentation tip.

To entrepreneur or not to entrepreneur? How identity discrepancies influence enthusiasm for academic entrepreneurship
Article discusses how recognizing the commercial potential of university-based inventions and discoveries, legislators and administrators have called upon academic scientists to become academic entrepreneurs. Few academic scientists are enthusiastic about taking on entrepreneurial activities, yet the intrinsic reasons for lack of enthusiasm are poorly understood. The authors extend the research by applying self-discrepancy theory to explore the role of future-oriented self and other guides on enthusiasm for academic entrepreneurship.

Dementia and COVID-19 among Older African American Adults: A Scoping Review of Healthcare Access and Resources
Article discusses how African American/Black communities comprise 12.2% of the U.S. population, with a COVID-19 infection rate of more than 18% and marginal access to healthcare services. This scoping review synthesizes the emerging evidence on healthcare accessibility among older African American adult communities with dementia and COVID-19, as well as the resource requirements for this population during the pandemic.

Reduced reflectance and altered color: The potential cost of external particulate matter accumulation on urban Rock Pigeon (Columba livia) feathers
Authors of the article state that airborne particulate matter (PM) can accumulate on feather surfaces and alter feather appearance, so they quantified PM accumulation on Rock Pigeon feathers and analyzed the spectral properties of extracted particulates. Their findings suggest that wild birds could incur an urban pollution penalty as PM accumulation has the potential to alter feather properties.

Urban Feature Extraction within a Complex Urban Area with an Improved 3D-CNN Using Airborne Hyperspectral Data
Article describes how airborne hyperspectral data has high spectral-spatial information, but mining and using this information effectively is still a great challenge. Therefore, a 3D-1D-CNN model was proposed for feature extraction in complex urban with hyperspectral images affected by cloud shadows.

Microstructure evolution and mechanical properties in a gas tungsten arc welded Fe42Mn28Co10Cr15Si5 metastable high entropy alloy
Article asserts that weldability studies on high entropy alloys are still relatively scarce, delaying the deployment of these materials into real-life applications, thus, there is an urgent need for in-depth studies of the weldability of these novel advanced engineering alloys. In the current work, an as-cast Fe42Mn28Co10Cr15Si5 metastable high entropy alloy was welded for the first time using gas tungsten arc welding.

Effectiveness of a Single Prolonged Aerobic Exercise Session on Executive Function Task Performance in Physically Active Adults (21–70 Years of Age)
Authors of the article sought to examine the effectiveness of an acute prolonged exercise session on post-exercise executive function in physically active adults and to assess if age or pre-exercise cognitive performance was predictive of the magnitude of change in executive task performance. Their results support the effectiveness of a single prolonged exercise bout to augment executive function in physically active adults, irrespective of age.

Homologues and homology and their related terms in phylogenetic systematics
Article describes how, in the field of phylogenetic systematics, the terms homology and homologue and their relationship to cladistic terms such as character, character state, synapomorphy and symplesiomorphy, as well as their relationships to each other, have been and are still discussed frequently. A recent re-emergence of concepts of homology/homologue free of any reference to explanatory hypotheses prompted the authors to explore these concepts and their relationships to each other as well as to the concept of morpheme, as introduced recently.

A Phosphonic Functionalized Biopolymer for the Sorption of Lanthanum (III) and Application in the Recovery of Rare Earth Elements
Authors of the article state that in the first step of their experiment, the sorption was investigated using La(III) ions before testing for the recovery of rare earth elements (REEs) from pretreated industrial acidic leachate. They infer that phosphonate groups participate in the sorption, and that the most effective sorption is at pH = 4.

Evolutionary models of lateralization: Steps toward stigmergy?
Article discusses an interesting approach to accounting for brain and behavioral asymmetry based on competition and cooperation in phenotypically asymmetric individuals. The model in question shows, in an almost fully analytical way, that under proper conditions, there exists an unequal number of equilibrium of left-and right-lateralized individuals.
