Prediction of hydrodynamic characteristics of a venturi scrubber by using CFD simulation

open access: yesSouth African Journal of Chemical Engineering, 2017
The filtered containment venting system (FCVS) is a safety relevant system, which consists of venturi scrubber and a mesh filter. FCVS needs to be further assessed to improve the existing performance of the venturi scrubber.

Nonthermal Plasma–Enabled Cascade N2 Activation and Electroreduction

open access: yesEcoEnergy, EarlyView.
Integrating plasma‐assisted NOx synthesis with subsequent electrochemical reduction enables the sustainable synthesis of high‐value N‐containing chemicals under ambient conditions. ABSTRACT The development of sustainable nitrogen fixation technologies operating under ambient conditions is critical for reducing the energy intensity and carbon footprint ...

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

open access: yesFood Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Design, performance, and demand for a novel in-line chlorine doser to increase safe water access

open access: yesnpj Clean Water, 2021
Financially sustainable strategies are needed to increase access to safe drinking water in low-income settings. We designed a novel in-line chlorine doser that employs the Venturi principle to automatically add liquid chlorine at the point of water ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

open access: yesHigh Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Association Between Anatomical Subsite and Invasive Disease in Head and Neck Lentigo Maligna and Lentigo Maligna Melanoma

open access: yesThe Journal of Dermatology, EarlyView.
ABSTRACT Lentigo maligna (LM) and LM melanoma (LMM) predominantly arise on chronically sun‐damaged head and neck skin and are often considered biologically uniform across facial locations. Whether invasive potential varies by anatomical subsite remains unclear.

Rice Orange Leaf Phytoplasma Imp Protein Blocks G–M Interaction by Binding Glycoprotein G to Suppress Rice Stripe Mosaic Virus Infection

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plants frequently encounter multiple pathogens concurrently, yet the molecular bases of pathogen–pathogen interactions during mixed infections remain largely unresolved. Here we show that co‐infection of rice by Rice orange leaf phytoplasma (ROLP) and Rice stripe mosaic virus (RSMV) markedly suppresses RSMV proliferation in both host plants ...

Rhizosphere Microbiomes Respond to Plant‐Parasitic Nematode Cues and Contribute to Host Defence

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant‐parasitic nematodes (PPNs) cause major crop losses, while current nematicides face increasing regulatory restrictions and often show inconsistent efficacy. We tested whether nematode‐associated cues activate rhizosphere microbiomes and cuticle‐associated fungi to produce suppressive metabolites that impair nematodes and stimulate host ...
