Soil surface temperatures reveal moderation of the urban heat island effect by trees and shrubs

open access: yesScientific Reports, 2016
Urban areas are major contributors to air pollution and climate change, causing impacts on human health that are amplified by the microclimatological effects of buildings and grey infrastructure through the urban heat island (UHI) effect.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

The Woody Planet: From Past Triumph to Manmade Decline

open access: yesPlants, 2020
Woodiness evolved in land plants approximately 400 Mya, and very soon after this evolutionary invention, enormous terrestrial surfaces on Earth were covered by dense and luxurious forests.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Fuelwood demand and supply in Rwanda and the role of agroforestry [PDF]

open access: yes, 2011
Fuelwood in Rwanda is assumed to come from forests and woodlands, thus contributing to large-scale deforestation. Available studies on fuelwood demand and supply support this assumption and indicate a continuously rising demand of fuelwood, notably from ...

Phenolic compounds as indicators of drought resistance in shrubs from Patagonian shrublands (Argentina).

open access: yesPlant physiology and biochemistry : PPB, 2016
UNLABELLED Plants exposed to drought stress, as usually occurs in Patagonian shrublands, have developed different strategies to avoid or tolerate the lack of water during their development.

Mass Spectrometry Imaging‐Assisted Discovery of Gallotannin Biosynthetic Genes in the Root of Paeonia suffruticosa

open access: yesAdvanced Science, EarlyView.
An integrated approach combining mass spectrometry imaging, transcriptomics, and phylogenetic analysis facilitated the efficient identification of genes involved in gallotannin biosynthesis in Paeonia suffruticosa. As a result, a key UGT and several SCPL acyltransferases responsible for biosynthesizing pentagalloylglucose were successfully identified ...

The Dendrochronological Potential of Some Shrub Species in Mongolian Dry Steppe

open access: yesMongolian Journal of Biological Sciences, 2020
Shrub expansion has been widely documented in Northern Hemisphere due to the climate change and land use impacts. The findings of some studies show that shrub expansion greatly corresponds with changes in temperature and precipitation in Arctic, whereas ...
