Ducted fuel injection: A new approach for lowering soot emissions from direct-injection engines

open access: yesApplied Energy, 2017
Abstract Designers of direct-injection compression-ignition engines use a variety of strategies to improve the fuel/charge-gas mixture within the combustion chamber for increased efficiency and reduced pollutant emissions. Strategies include the use of high fuel-injection pressures, multiple injections, small injector orifices, flow swirl, long ...

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

open access: yesEcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

Ducted Fuel Injection vs. Free-Spray Injection: A Study of Mixing and Entrainment Effects Using Numerical Modeling

open access: yesSAE International Journal of Engines, 2020
<div>Diesel engines are an important technology for transportation of both people and goods. However, historically they have suffered a significant downside of high soot and nitrogen oxides (NO<sub>x</sub>) emissions. Recently, ducted fuel injection (DFI) has been demonstrated to attenuate soot formation in compression-ignition ...

Prevention of Early Onset of Breast Cancer With Ashwagandha

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT Prevention of breast cancer is feasible because many risk factors for this malignancy are known (e.g., family history, reproductive factors, etc.). Medicinal plants and/or their bioactive phytochemicals are attractive for the prevention of early onset of breast cancer due to their generally favorable safety profile.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Regulating Lipid Metabolism in Cancer: The Therapeutic Potential of Traditional Chinese Medicine

open access: yesPhytotherapy Research, EarlyView.
By regulating the reprogramming of lipid metabolism in tumor cells, TCM provides a novel strategy for antitumor therapy with reduced toxicity and enhanced efficacy. ABSTRACT Lipid metabolic reprogramming is a key feature of tumor cells to adapt to the microenvironment and plays an important role in tumor growth, invasion, and metastasis.

Intelligent Continuum Micromachines in Complex Confined Spaces

open access: yesSmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Cancer pain: current practice and emerging targets

open access: yesBritish Journal of Pharmacology, EarlyView.
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐
