title: Enhancing chemoselectivity of on-surface reactions on reconstructed Au(110): the case of a pentalene-bridged polyacene analogue

description: Polyacene analogues, consisting of short acene segments separated by nonbenzenoid rings, offer intriguing electronic properties and magnetic interactions. Pentalene-bridged polyacenes (PPs), in particular, hold promise for enhancing the electrical conductivity and potential open-shell ground states. However, PPs have remained elusive in solution chemistry due to poor solubility and limited synthetic protocols. In a recent publication,  we report the on-surface synthesis of PPs through the annulation between ortho-xylene groups. Scanning tunneling microscopy and atomic force microscopy reveal that the reconstructed Au(110) surface significantly enhances the chemoselectivity of the annulation process. Scanning tunneling spectroscopy combined with density functional theory suggests that PP exhibits a narrow direct band gap, similar to long acenes. This work demonstrates the potential for band structure engineering in polyacene analogues by incorporating nonbenzenoid rings, paving the way to advancements in organic electronics and spintronics. This record contains computational data supporting the results discussed in the manuscript.

title: Dataset Cumulative CO2 Emissions of International Transport

description: This dataset considers the year 1783, when the first steamship was built, as the first year of the international transport CO2 emissions.

The global cumulative CO2 emissions including international transport are converted to the 1875 baseline, similar to the Global Warming baseline (1850-1900).

title: Hierarchical eco-zone delineation in data-scarce Afrotropical River landscapes using global datasets

description: This repository contains data, statistics and maps on the hierarchical ecological zonation of Uganda using machine learning algorithms and global environmental datasets. The framework employs a systematic five-step approach integrating GIS analysis, statistical processing, and unsupervised hierarchical clustering to delineate ecological boundaries based on climate, topography, and vegetation patterns.

Methodology: The eco-zonation process utilised 16 environmental parameters derived from global datasets, including WorldClim bioclimatic variables (1970-2000), SRTM elevation data, and surface water extent maps. Zonal statistics were calculated for micro-watersheds based on HydroSHEDS level-10 basins intersected with 1 km elevation contours. Hierarchical clustering analysis using Euclidean distance and agglomerative clustering identified optimal cluster numbers through silhouette analysis. Random forest models determined key environmental drivers at each hierarchical level.

Validation:The framework was validated against 34 Potential Natural Vegetation (PNV) types using supervised random forest classification. Cross-validation achieved accuracies exceeding 59.87% across all hierarchical levels, with the highest performance (88.68%) at the ecoregion level. Indicator species analysis identified statistically significant vegetation associations within each ecological zone.

Results:Uganda's 241,147 km² terrestrial area was stratified into five ecoregions: Central-Northern Plains (CNP), Southern Savanna-Woodland Landscapes (SSWL), Karamoja Dry Steppe (KDS), Lake Victoria-Kyoga Wetland-Woodlands (VKWW), and Montane-Alpine Ranges (MAR). These were further subdivided into 8, 12, and 20 bioregions at three successive hierarchical levels. Monthly precipitation patterns and wetland distribution emerged as primary drivers across all spatial scales.

Repository Contents:

This repository contains the datasets, scripts, and workflows for the hierarchical delineation and validation of eco-zones in Uganda’s Afrotropical river landscapes. The project integrates global environmental datasets with open-source machine learning algorithms to produce spatially consistent, ecologically meaningful eco-zonation maps.

Workflow

> Abiotic Delineation: Hierarchical clustering of climate, topography, and hydrology variables to define eco-zones at multiple scales.

> Biotic Validation: Random Forest classification and Indicator Species Analysis (ISA) using Potential Natural Vegetation (PNV) to assess ecological coherence.

Included Materials



Raw and processed datasets for both abiotic and biotic steps

R scripts and R Markdown workflows for reproducible analyses

Output files, including maps, tables, and validation metrics


This framework provides a reproducible, open-data-driven approach for eco-zone mapping in data-scarce tropical landscapes.
