Preprint ecosystems [PDF]

open access: yesScience, 2017
In 1991, an electronic system through which interested parties could access non-peer-reviewed physics papers was launched by Paul Ginsparg at Los Alamos National Laboratory. This evolved into the “preprint” server arXiv, which has played a central role in information sharing in physics, mathematics, and related fields over many years.

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

open access: yesAdvanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Spin‐Dependent Generation of Surface‐Bound Radicals Toward Selective and Long‐Lasting Water Purification

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Innovation ecosystems

open access: yes
Innovation ecosystems are collectives of diverse, yet complementary, actors collaborating to generate system-level outcomes. Despite growing research interest, the role of “innovation” within innovation ecosystems remains unclear. We first distinguish innovation ecosystems from other innovation-oriented collectives such as alliances and networks ...

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...
