Advanced Nano‐Fibrillated Cellulose/Modified MXene Janus Membrane for Continuous 24‐h Water‐Power Co‐Generation

open access: yesAdvanced Functional Materials, EarlyView.
The Janus membrane integrates a superhydrophilic CNF@CTAB‐MXene layer with a superhydrophobic PTFE layer, enabling efficient solar‐driven water evaporation and electricity generation. It achieves an evaporation rate of 1.51 kg m−2 h−1 with excellent salt resistance and long‐term stability.

Deciphering a New Electrolyte Formulation for Intelligent Modulation of Thermal Runaway to Improve the Safety of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Diels‐Alder clicks chemistry addresses thermal runaway in lithium‐ion batteries. A thermoresponsive electrolyte with lithium salt in vinylene carbonate (VC) and 2,5‐dimethylfuran (DMFu) operates at room temperature but undergoes Diels‐Alder reactions at high temperatures, enabling a two‐step safety mechanism: a warning phase at ≈100 °C and complete ...

A new robust LMI-based model predictive control for continuous-time uncertain nonlinear systems

open access: yesAutomatika, 2020
This paper presents a new robust predictive controller for a special class of continuous-time non-linear systems with uncertainty. These systems have bounded disturbances with unknown upper bound as well as constraints on input states.

Gas Turbine Aerodynamics Improvement Via a Design of Intelligent Fractional Control

open access: yesJournal of Mechanical Engineering, 2021
Gas turbines are complex processes characterized by the instability and uncertainty of various sources. The range of useful operating in an axial compressor which is part of a turbine gas is limited by aerodynamic instabilities that are surge and ...

Transformation of Surges

open access: yesCoastal Engineering 1966, 1966
This paper deals with the transient deformation of surges (bores) both theoretically and experimentally. Ideal surges in open channels would normally disperse into periodic waves and be transformed to the undular bore. A train of these dispersive waves may finally reach some stable form e.g. solitary or cnoidal vwaves.

Compressor surge control using a new robust adaptive method in the presence of uncertainty and unmatched disturbance

open access: yesSystems Science & Control Engineering, 2020
The surge is the most common and important instability associated with compressors and its control is very important due to its damaging effects on the compressor system. This paper presents a new method of surge control using a robust adaptive method in

Dynamics and Impacts of the May 8th, 1902 Pyroclastic Current at Mount Pelée (Martinique): New Insights From Numerical Modeling

open access: yesFrontiers in Earth Science, 2020
The Mount Pelée May 8th, 1902 eruption is responsible for the deaths of more than 29,000 people, as well as the nearly-complete destruction of the city of Saint Pierre by a single pyroclastic current, and is, sadly, the deadliest eruption of the 20th ...
