In Situ and Ex Situ Conservation Measures

open access: yes
Abstract The effects of climate change and biodiversity loss are global and not limited by national borders, with forest ecosystems, in particular, suffering under increasing pressure. To preserve and maintain species genetic diversity, well-considered in situ and ex situ measures are needed.

A Porous Interfacial Photothermal Layer of Fused Core–Shell Carbon‐Polymer Nanospheres for Directional Salt Crystallization and Zero‐Liquid‐Discharge

open access: yesAdvanced Materials, EarlyView.
A hierarchical hydrogel evaporator with a thin, porous photothermal layer of fused core–shell carbon‐polymer nanospheres enables ultrafast interfacial solar evaporation with minimized heat loss and sufficient water supply. Directional advection‐dominated brine transport, coupled with Marangoni‐driven interfacial flow, drives salt away from the active ...

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Cost of Conservation of Agrobiodiversity [PDF]

open access: yes
The cost of conservation of germplasm stored in gene banks i.e., ex-situ collections has been studied in other parts of the world to estimate direct and indirect contributions by various actors involved in conservation.

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...

Genetic Variability Analysis of the Polyploid Complex of Acacia nilotica (L.) Willd. Using RAPD Markers [PDF]

open access: yesTropicultura, 2008
The genetic variability of nine Acacia nilotica subspecies of various origins was analyzed by thirty-six RAPD primers. Sixteen among them produced polymorphic bands and generated 166 polymorphic markers.

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...
