The anti-depression effect and potential mechanism of the petroleum ether fraction of CDB: Integrated network pharmacology and metabolomics [PDF]

Heliyon
The combination of Chaidangbo (CDB) is an antidepressant traditional Chinese medicine (TCM) prescription simplified by Xiaoyaosan (a classic antidepressant TCM prescription) through dismantling research, which has the effect of dispersing stagnated liver

Spatial Engineering of Gas Diffusion Layers Overcomes Mass Transport Limitations in Fuel Cells [PDF]

Advanced Science, Volume 13, Issue 50, 7 September 2026.
ABSTRACT Mass transport limitations at high current densities hinder polymer electrolyte fuel cell (PEFC) performance due to inefficient water management and reactant distribution. Gas diffusion layer (GDL) perforation offers a potential solution as an alternative to complex flow‐field modifications.

XAFS measurement system using undulator synchronized on‐the‐fly monochromator scan at SPring‐8 BL36XU [PDF]

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1478-1485, September 2026.
Nonlinear scanning of a compact channel‐cut monochromator synchronized with an undulator‐gap movement system enables fast high‐flux X‐ray absorption fine structure measurements.In X‐ray absorption fine structure (XAFS) measurements at undulator beamlines, it has been difficult to simultaneously achieve both spectral time resolution and high X‐ray flux ...

Novel PEFC Application for Deuterium Isotope Separation [PDF]

Materials, 2017
The use of a polymer electrolyte fuel cell (PEFC) with a Nafion membrane for isotopic separation of deuterium (D) was investigated. Mass analysis at the cathode side indicated that D diffused through the membrane and participated in an isotope exchange reaction. The exchange of D with protium (H) in H2O was facilitated by a Pt catalyst. The anodic data

How Mixed Are Production‐Oriented Planted Forests? A Global Review and Classification Approach [PDF]

Global Change Biology, Volume 32, Issue 9, September 2026.
We conducted a global review of production‐oriented mixed planted forests (MPF) and developed a standardized index to classify their admixture level using a multi‐criteria decision analysis (PROMETHEE II). The review considers 153 studies and 253 plots, and the MPF Index (scale 0–1) integrates multiple design indicators related to species composition ...
