Meta-analysis of ecosystem services associated with oyster restoration. [PDF]

Conserv Biol, 2023
Abstract Restoration of foundation species promises to reverse environmental degradation and return lost ecosystem services, but a lack of standardized evaluation across projects limits understanding of recovery, especially in marine systems. Oyster reefs are restored to reverse massive global declines and reclaim valuable ecosystem services, but the ...

Tree Diversity Increases Carbon Stocks and Fluxes Above-But Not Belowground in a Tropical Forest Experiment. [PDF]

Glob Chang Biol
We examined the potential of mixed‐species planted forests compared to monospecific forests to act as a nature‐based solution to climate change mitigation through carbon sequestration. By analysing multiple carbon stocks and fluxes over 16 years in the world's oldest tropical tree diversity experiment, we found that planted forests with five tree ...

Photochemically Induced Propulsion of a 4D Printed Liquid Crystal Elastomer Biomimetic Swimmer. [PDF]

Adv Sci (Weinh)
4D printing of azobenzene‐containing liquid crystal elastomers (LCEs) actuating at low temperatures close to room temperature is demonstrated. Elastomer irradiation with moderate‐intensity ultraviolet light leads to fast photodeformation underwater indicating predominant photochemical response.

Chiral Single‐Molecule Potentiometers Based on Stapled ortho‐ Oligo(phenylene)ethynylenes

Angewandte Chemie, Volume 135, Issue 16, April 11, 2023., 2023
A stapled chiral helical single‐molecule potentiometer based on ortho‐oligophenylethynylene skeleton is described. Its stretching during STM measurements promotes different conductive pathways, attributed to different conformations of the helical scaffold, while maintaining the helicity. State of the art calculations on polarization pave the way to use

Highly Efficient Photoninitiators Based on 4H‐Pyranylidene Derivatives for Two‐Photon Laser Printing

Advanced Materials Technologies, Volume 8, Issue 23, December 13, 2023., 2023
4H‐pyranylidene derivatives with a donor–acceptor–donor structure are studied as photoinitiators for two‐photon laser printing, showing a better performance than the benchmark BAPO. Abstract A series of four donor–acceptor–donor derivatives bearing 4H‐pyranylidene and 4‐methylcyclohexan‐1‐one units as donor and acceptor groups respectively is designed,

Could a trade agreement strengthen the enforcement of domestic environmental laws? Envisioning the impacts of the US–Peru environmental submissions mechanism

Review of European, Comparative &International Environmental Law, Volume 32, Issue 3, Page 465-472, November 2023., 2023
Abstract Could a trade agreement strengthen the enforcement of domestic environmental laws? This article explores this question in the context of the US–Peru Trade Promotion Agreement (TPA). The article examines, in particular, the potential role of the Secretariat for Submissions on Environmental Enforcement Matters (SEEM) of the TPA.

Seedling growth declines in warmed tropical forest soils

Biotropica, Volume 55, Issue 5, Page 897-910, September 2023., 2023
The response of tropical forest plants to a warming climate could have a large feedback on further climatic change. To address this, we tested the response of six tree species seedlings to 3 years of in‐situ experimental soil warming. Our study demonstrates that belowground warming causes species‐specific declines in the growth and photosynthesis of ...

Melt Electrowriting of Liquid Crystal Elastomer Scaffolds with Programmed Mechanical Response

Advanced Materials, Volume 35, Issue 14, April 6, 2023., 2023
Melt electrowriting of liquid crystal elastomers is developed to generate ultrafine fibers with built‐in digitally defined anisotropy. Square lattice and other more complex scaffolds with structural features and dimensions hardly accessible with conventional extrusion‐based printing techniques, as well as mechanical response to temperature, are ...

Remoción de materia organica natural por tratamiento convencional de agua en un río tropical

Tecnología en Marcha, 2022
En Costa Rica, la efectividad del tratamiento convencional de agua es evaluada principalmente en términos de remoción de color y turbidez y no de materia orgánica natural (MON) que, al clorarla, puede formar subproductos de desinfección (DBPs ...

Coordinative Self‐assembly of π‐Electron Magnetic Porphyrins

Angewandte Chemie, Volume 137, Issue 9, February 24, 2025.
Gold‐coordinated polymers of π‐extended porphyrins were fabricated by on‐surface synthesis and coordination chemistry methods. Each porphyrinoid monomer features antiferromagnetic coupling and no interaction between nearest neighbors within the polymer backbone, behaving as a single magnetic entity.
