Drone methodologies: Taking flight in human and physical geography

open access: yes, 2018
Suddenly drones seemed to be everywhere. The buzzing props, blinking lights and tiny cameras were whizzing across remote areas, confusing wildlife. They hovered over urban parks, capturing footage of firework shows and weddings.

Coupling Interfacial Redox‐Reactions with In Situ Proton Generation for the Photoelectrochemical Separation of Rare‐Earth Elements

open access: yesAdvanced Functional Materials, EarlyView.
To enhance the sustainability of electrochemical separations for resource recovery, a photoelectrochemical ion recovery system is developed that utilizes renewable solar energy. A composite integrating titianium dioxide nanorods and a redox‐copolymer enables spontaneous cation adsorption and light‐activated redox reactions for regeneration, thus ...

Rainfall and human activity impacts on soil losses and rill erosion in vineyards (Ruwer Valley, Germany) [PDF]

open access: yesSolid Earth, 2015
Vineyards are one of the eco-geomorphological systems most conditioned by human activity in Germany. The vineyards of the Ruwer Valley (Germany) are characterized by high soil erosion rates and rill problems on steep slopes (between 23 and 26°) caused by

Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

open access: yesAdvanced Functional Materials, EarlyView.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.

The importance of mountain geomorphosites for environmental education: examples from the Italian Dolomites and the Swiss Alps

open access: yesActa Geographica Slovenica, 2016
Because of their specific physical characteristics (altitude, slope, orientation, climate), mountain environments have an important natural diversity. In particular, their geodiversity is generally much larger than in the lowlands, and because mountain ...
