Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Inter‐Crystal Spacing of Implantable Polymeric Surfaces as a Key Suppressor of Microbial Adhesion.

Small, EarlyView.
Biofilm formation on implantable devices is addressed by controlling inter‐crystal spacing in shape memory polymers. Repeated shape recovery aligns and enlarges crystalline phases and reduces amorphous regions, enhancing bacterial repellency. Three biofilm‐forming bacteria show reduced adhesion, and a one‐year dog bile‐duct model maintains function ...

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Laser‐Induced‐Structural Transformation in Ti3CNTx MXene Monitored by Raman Spectroscopy with DFT Insight

Small, EarlyView.
A multi‐wavelength Raman study of microwave‐assisted hydrothermal Ti3CNTx MXene, supported by theoretical calculations, identifies laser‐power thresholds and evaluates its ambient‐condition stability. ABSTRACT MXenes are emerging 2D nanomaterials that have attracted growing attention for their highly tunable atomic structure, composition, and surface ...

Supercapacitive Carbon‐Coated δ‐MnO2 Nanosheets as a Solid‐Contact Material for Self‐Testing Potassium‐Ion Biosensors

Small, EarlyView.
A simple and energy‐efficient method was developed to synthesize carbon‐coated δ‐MnO2 nanosheets (δ‐MnO2@C). This multifunctional material serves as both a supercapacitor electrode and a solid‐contact for self‐testing K+‐ion biosensors. Compared to activated carbon, δ‐MnO2@C enhances Faradaic supercapacitive properties, improving the K+‐ion sensing ...
