Surprising Water Slipping Performance on Highly Hydrophilic PEG‐Derived Monolayer‐Covered Surfaces: Preparation, Mechanism, and Application

open access: yesAdvanced Functional Materials, EarlyView.
Highly hydrophilic surfaces (water contact angle, ≈17.7°) exhibiting surprising water slipping performance (sliding angle, ≈7.3°) are successfully prepared via simple chemisorption of polyethylene glycol (PEG) organosilane and subsequent alkali‐treatment.

Development of a Compound Energy System for Cold Region Houses using Small-Scale Natural Gas Cogeneration and a Gas Hydrate Battery [PDF]

open access: yes, 2015
In this study, an independent energy system for houses in cold regions was developed using a small-scale natural gas CGS (cogeneration), air-source heat pump, heat storage tank, and GHB (gas hydrate battery). Heat sources for the GHB were the ambient air

Two isostructural carbamates: the o-tolyl N-(pyridin-3-yl)carbamate and 2-bromophenyl N-(pyridin-3-yl)carbamate monohydrates

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The title carbamate monohydrates, C13H12N2O2·H2O and C12H9BrN2O2·H2O, form isomorphous crystals that are isostructural in their primary hydrogen-bonding modes.

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Initiation and expansion of layered fracture in sediments due to thermal-induced hydrate dissociation

open access: yes, 2015
Methane hydrate dissociation in sediment may lead to geological hazards such as marine landslide, collapse of wellbore. The physical mechanisms, especially on the evolution of sediment damage, are not very clear sediment though some numerical simulations

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

open access: yesAdvanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
