Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

open access: yesAdvanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

open access: yesAdvanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

"Projection-Perception" Image Differences and Optimization Paths in China's National Park System Pilot Areas

open access: yesRedai dili
Based on the theories of "projection-perception" and wooden barrels, we take the online travelogue text as the research object, use the methods of online text analysis and constituent distance analysis to compare the official projected image of China's pilot zones of national parks with the perceived image of the tourists, and use the 2-dimensional 4 ...

Saguaro National Park

open access: yes, 1933
Owl clover; Saguaro National Monument was created on March 1, 1933 by President Herbert Hoover. On October 14, 1994, Congress elevated Saguaro to National Park status. The park is divided into two sections, called districts, lying approximately 20 miles (

Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water

open access: yesAdvanced Materials, EarlyView.
An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...
