Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Charge Transport in Ternary Charge‐Transfer Solid Solution Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
This study deconvolutes the roles of indirect (superexchange) and direct electronic coupling on charge transport in single crystals of an organic charge‐transfer molecular semiconductor (OSC). This model system elegantly demonstrates that structural defects introduced by chemical dopants play a significant role in the electronic performance ...

Ongoing study on the integration of biodiversity concerns in management of forest concessions in Central Africa [PDF]

open access: yes, 2008
Central Africa is home to the world's second largest contiguous tropical rainforest, after Amazon. Depending on countries in the sub-region, between 10% to 15% (Nasi, Cassagne, Billand, 2006) of the forests' surface area is occupied by protected areas ...

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications

open access: yesAdvanced Functional Materials, EarlyView.
Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Studies on Sedum taxa found in Sicily (Italy) for Mediterranean extensive green roofs

open access: yesItalian Journal of Agronomy, 2018
One type of green roof whose function is ecological and environmental rather than aesthetic is the extensive green roof. Many studies have shown that Sedum performs very well compared to other hardy species in substrates of less than 10 cm. It seems that

Abitibi's approach to forest certification

open access: yesThe Forestry Chronicle, 1996
Forest Certification is one of the priority issues facing the forest industry and will become increasingly more important as we move towards the year 2000. It will provide a voluntary, impartial process for each company to demonstrate to the general public, customers and Government, that its forest management practices meet or exceed established ...

Nanodiamond‐Based Quantum Sensing Reveals Changes in Endo‐Lysosomal Activity of Stimulated Cardiac Fibroblasts in a Cellular Fibrosis Model

open access: yesAdvanced Functional Materials, EarlyView.
Quantum sensing reveals intricate patterns linking endo‐lysosomal maturation to cardiac fibrosis progression, highlighting complexity in cellular remodeling. This study investigates fibroblast‐to‐myofibroblast transition under cell aging, stiffness, and TGF‐β stimulation, comparing nanodiamond uptake, endo‐lysosomal dynamics, and free radical ...

Green public procurement of certified wood : impact on international trade and global welfare [PDF]

open access: yes, 2015
This paper investigates the impact of green public procurement (governments’ purchases) of certified wood in the EU. A spatial partial price equilibrium model is developed to analyse whether this policy impacts interregional trade flows of wood and other
