From Grave to Cradle: Kombucha Waste for Sustainable Electronics
Advanced Science, EarlyView.This study introduces a sustainable method to purify kombucha bacterial cellulose (KBC) with sodium bicarbonate and hydrogen peroxide, avoiding harsh chemicals. KBC films are patterned with gold and function as pressure sensors for flatfoot gait detection. At the end‐of‐life, the KBC‐based device biodegrades in soil, leaving environmentally benign gold

Angewandte Chemie, EarlyView.A molecular cage exhibits strong entropy‐driven encapsulation of perfluoroalkyl substances (PFAS), accommodating up to four short‐chain guests as anionic aggregates. Guided by these molecular‐level insights, a novel host‐in‐host adsorbent is developed: mesoporous silica doped with 1 wt% cage achieves >98% removal of short‐ and long‐chain PFAS with full

A Theoretical Solution for Pile-Supported Embankment with a Conical Pile-Head
Applied Sciences, 2019 This paper, with a focuses on the pile-supported embankment with a conical pile-head, proposes a theoretical solution which incorporates all the load transfer mechanisms, namely the soil arching effect, the pile−soil interaction, and the support ...

Large-scale physical modelling of soil-filled masonry arch bridges [PDF]
International Journal of Physical Modelling in Geotechnics, 2018 The presence of soil backfill has been shown to have a significant influence on the load-carrying capacity of masonry arch bridges, with the soil fill providing a number of important functions, including inter alia, the distribution of surface loads and passive resistance to arch deformation during loading.

Advanced Science, EarlyView.General schematic of the approach. Abstract Conventional Silver/Silver Chloride (Ag/AgCl) electrodes remain the clinical standard for electrophysiological monitoring but are hindered by poor skin conformity, mechanical rigidity, and signal degradation, particularly under motion or sweat.

Analysis of The arching phenomenon of bored piles in sand
Alexandria Engineering Journal, 2016 Several bored pile field-testing observations showed the arching phenomena and its effect on side shear resistance. Finite element numerical model is developed in this paper to study the arching phenomena of bored pile and the effect on the overall ...

Advanced Science, EarlyView.This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...
