AutoChamber: A broadly accessible 3D‐printed floating chamber to automate measurements of greenhouse gas emissions from surface waters

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Fresh waters provide environmental conditions that favour microbial CO2 and CH4 production, leading to the release of large quantities of greenhouse gases (GHG) to the atmosphere. Despite their importance, these fluxes remain poorly defined, weakening estimates of global GHG budgets that are critical in implementing effective climate ...

The effects of soil moisture, soil texture, and host orientation on the ability of Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae) to infect Galleria mellonella (Lepidoptera: Pyralidae) [PDF]

open access: yes, 2018
Entomopathogenic nematodes (EPN) demonstrate potential as a biological control for soil dwelling insects. However, edaphic factors, such as soil moisture and texture impact the efficacy of EPN on a host. The objectives were to examine the effects of soil

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

open access: yesAgricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, Volume 45, Issue 3, Page 487-496, March 2026.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Physiological non-Newtonian blood flow through single stenosed artery [PDF]

open access: yesTheoretical and Applied Mechanics, 2016
A numerical simulation to investigate the Non-Newtonian modeling effects on physiological flows in a three dimensional idealized artery with a single stenosis of 85% severity is given. The wall vessel is considered to be rigid.

Distribution of Interstitial Cells and Differentiating Nematocytes in Nests in Hydra attenuata [PDF]

open access: yes, 1974
We have used tissue maceration to quantitate interstitial cell nests in Hydra attenuata and thiolacetic acid-lead nitrate staining to quantitate differentiating nematocytes. Most I-cell nests have 2, 4, 8, or 16 cells.

Integrating Optical Feedback Alignment and Fluidic Control for Multiphase Flow‐Assisted In Situ 3D Printing

open access: yesJournal of Separation Science, Volume 49, Issue 2, February 2026.
ABSTRACT Additive manufacturing is transforming how microfluidic devices are prototyped and fabricated. Among various 3D printing methods, stereolithography (SLA) has become a dominant technique for microfluidics due to its high resolution and design flexibility, with widespread use in lab‐on‐a‐chip applications.
