Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

open access: yesAdvanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications

open access: yesAdvanced Functional Materials, EarlyView.
Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Spectroscopic Studies of Brooker\u27s Merocyanine in Zeolite L [PDF]

open access: yes, 2016
Zeolites are porous, crystalline substances that have very unique atomic organizations which allow for the formation of complex channels within the crystals. Each type of zeolite has a distinct shape and structure.

Exciton‐Polaritons in Nanoscale Metal‐Organic Frameworks: A Platform for the Reversible Modulation of Strong Light‐Matter Coupling via the Chemical Environment

open access: yesAdvanced Functional Materials, EarlyView.
Strong exciton‐photon coupling is achieved by integrating porphyrin ligand‐based MOF nanoparticles in optical cavities, as evidenced by pronounced polariton branch anticrossing. The porous nature of the resonator enables precise, reversible tuning via vapor pressure, unlocking unprecedented chemical‐environment controlled dynamic polaritonic platforms ...

Hydrogen Fire Detection System Features Sharp Discrimination [PDF]

open access: yes, 1966
Hydrogen fire detection system discovers fires by detecting the flickering ultraviolet radiation emitted by the OH molecule, a short-lived intermediate combustion product found in hydrogen-air flames.

Conformal Polymer Electrolyte Enabled by Nitrile Coordination for Long‐Cycle Solid‐State Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The replacement of α‐H with methyl groups markedly improves the compatibility between the electrolyte and lithium metal, facilitating the formation of a conformal SEI layer that effectively accommodates volume variations in lithium metal during cycling.

Fighting to Save a Nation: Volunteerism and London’s Auxiliary Fire Service in the Blitz [PDF]

open access: yes, 2015
The London Blitz of 1940 is one of the most horrifying events of World War 2. For the first time, citizens were the primary target in an attempt to shock Britain into surrender. The Blitz opened a new chapter in the book of WWII.

Are Forest Fires Predictable?

open access: yes, 2002
Dynamic mean field theory is applied to the problem of forest fires. The starting point is the Monte Carlo simulation in a lattice of million cells. The statistics of the clusters is obtained by means of the Hoshen--Kopelman algorithm.
