Locating Little Larvae: Environmental DNA Methods Can Detect a Rare Fish Species Under Field Estuarine Conditions

open access: yesEnvironmental DNA
Rare species are difficult to monitor using traditional methods, making them excellent candidates for environmental DNA (eDNA) monitoring. The larval life stages of Delta Smelt (Hypomesus transpacificus) and Longfin Smelt (Spirinchus thaleichthys) are ...

Design of a Three‐Phase PWM Rectifier Based on Improved Whale Optimization Algorithm Optimized Fuzzy Control

open access: yesAdvanced Control for Applications, Volume 8, Issue 3, September 2026.
Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Living Crystallization‐Driven Self‐Assembly: Entering an Era of Functional Customization

open access: yesAggregate, Volume 7, Issue 7, July 2026.
Living CDSA achieves fine regulation of nanostructures when adopting block copolymers as basic units. Researchers can realize functional customization by means of intrinsic design, exogenous modification, and surface engineering. The developed multifunctional nanomaterials find wide applications in catalysis, optoelectronics, and biomedicine.

Multi‐Site Chelation Enabled by 3D‐Printed TiO2 Hydrogel Monoliths for Dynamic Ge(IV) Recovery in Fixed Beds

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Functional Response of Protected Larval Stage Delta Smelt (Hypomesus transpacificus)

open access: yes, 2012
Delta smelt (Hypomesus transpacificus) is a protected slender-bodied fish endemic to the San Francisco Estuary. Smelt prey upon various zooplankton including the copepods such as Pseudodiaptomus forbesi.

Zinc Isotopes Reveal Cross‐Border Transport of Coal Combustion Pollutants Across the Himalayas During the Summer Monsoon

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Himalayas form a major atmospheric barrier between South Asia and Tibetan Plateau, yet cross‐barrier transport of anthropogenic metals remains poorly constrained. We use moss δ66Zn along a 750–4,100 m a.s.l. south‐north transect in Motuo to trace pollution sources and transport processes. On the southern slope, trace metals (Zn, Pb, As, Ni,
