“Win‐Win” Structural Engineering of Chinese Herb Residues‐Derived Porous Graphitic Carbons: Decoupling the Porosity‐Graphitization Antagonism for Ultrahigh‐Rate Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work proposes a strategy that overcomes the porosity‐graphitization antagonism in carbon materials, converting Sargentodoxa cuneata residue into porous graphitic carbons to enable sustainable, high‐performance energy storage from biomass waste. The antagonism between porosity and graphitization critically limits carbon supercapacitor performance ...

Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

open access: yesEnergy Science &Engineering, EarlyView.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the

Computational Analysis of Spray Angle Effects on Combustion and Emissions in Methane‐Diesel Dual‐Fuel Engine

open access: yesEnergy Science &Engineering, EarlyView.
This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.

The dynamic braking of induction motors.

open access: yes, 1985
The dynamic braking of induction motors is investigated with particular emphasis on the use o-f zero-sequence connections. The braking performance using both AC and DC supplies is compared. A mathematical model is developed to predict both the transient and steady-state zero-sequence braking performance.
