Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Transition voltage of AlGaN/GaN heterostructure MSM varactor with two-dimensional electron gas

, 2017
It is not in principle clear which of the capacitors forming a varactor is responsible for the capacitance change at the transition voltage. We analyzed a theoretical case of transition voltage of the varactor formed by ideal Schottky diodes.

Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography

Advanced Functional Materials, EarlyView.
In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

Modeling instantaneous interfacial voltage drop in electroosmosis

Electroosmosis can be used in dewatering practice. Dewatering results are closely related to electric current transmission efficacy in soil. Electrode-soil interfaces are widely recognized as locations where electric power adversely loses, causing ...

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

Advanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Advanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

Highly Efficient and Stable Roll‐to‐Roll Coated Perovskite Solar Cells Enabled by Antisolvent Vapor‐Assisted Crystallization

Advanced Functional Materials, EarlyView.
Antisolvent Vapour‐Assisted Crystallization (AVAC) enables controlled perovskite crystallization through precisely metered antisolvent vapour, eliminating liquid antisolvent waste. Compatible with roll‐to‐roll (R2R) slot‐die coating, AVAC produces uniform, pinhole‐free films with enlarged grains, delivering efficiencies of 18.3% for R2R fabricated ...
