Physics of secondary flow phenomenon and erosion characteristics in the injector of a Pelton turbine

open access: yesEngineering Applications of Computational Fluid Mechanics
The Pelton turbine is widely used in the development of high-head hydraulic resources. However, in high-altitude mountainous regions, multiple sediment environments, along with secondary flows generated within the cross-sections of the turbine's ring and

Deciphering Cold Stress Resilience: Multiomics Insights in Contrasting Wheat Genotypes From the Western Himalayas

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Polar Lipid and Fatty Acid Profiles of Oat Groats Substantially Influenced by Field Management: A Comparison of Cultivars, Sowing Times and Fertilizer Composition

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The polar lipids in oat grains are crucial due to their biological functions, nutritional quality, potential use in food flavour and processing, the protection they provide against biotic and abiotic stresses, and their ability to act as cellular signalling molecules.

Numerical Study of Heat Transfer Enhancement Using Nano-Encapsulated Phase Change (NPC) Slurries in Wavy Microchannels

open access: yesFluids
Researchers have attempted to improve heat transfer in mini/microchannel heat sinks by dispersing nano-encapsulated phase change (NPC) materials in base coolants. While NPC slurries have demonstrated improved heat transfer performance, their applications

RENAL‐CHIP: Rejection Evaluation via Non‐Invasive Analysis of Circulating Podocytes With Herringbone‐Chip Isolation Platform

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
RENAL‐CHIP converts 1 mL of peripheral blood into a biopsy‐equivalent readout of renal‐allograft fate. By magnetic capture and release of donor‐derived circulating podocytes through a herringbone microfluidic chip, 84% capture, 96% release and single‐cell RNA evidence of rejection‐specific immunity are achieved.

Beyond Beer‐Lambert Linear Regression: Multi‐Layer Modeling for Wide‐Range Concentration Quantification Using Ultraviolet‐visible Spectroscopy

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Ultraviolet–visible (UV‐Vis) spectroscopy is widely used for chemical quantification due to its simplicity and low cost; however, accurate concentration prediction becomes challenging when target concentrations span wide ranges, where the global linearity assumption of the Beer‐Lambert law often breaks down.

Dean Flow Dynamics in Low-Aspect Ratio Spiral Microchannels

open access: yes, 2017
A wide range of microfluidic cell-sorting devices has emerged in recent years, based on both passive and active methods of separation. Curvilinear channel geometries are often used in these systems due to presence of secondary flows, which can provide ...
