Microlasers Made Entirely from Edible Substances

open access: yesAdvanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Non‐Reciprocal Terahertz Topological Sensor on a Silicon Chip

open access: yesAdvanced Optical Materials, EarlyView.
A non‐reciprocal terahertz topological sensor (NTTS) is experimentally demonstrated on a silicon valley photonic crystal chip by detecting the thickness and position changes of a polyimide membrane. The sensor exploits detuning between clockwise and counterclockwise topological cavity modes, induced by integrated magneto‐optical InSb, to achieve non ...

Advances and Outlook of Nickel‐Based MOFs–LDHs Materials for Energy Conversion

open access: yesAdvanced Sustainable Systems, EarlyView.
In this graphical abstract, we present the pivotal gap between the activity and stability parameters as far as intergrated Ni‐based MOF/LDF electrocatalysts are concerned. For large scale application, these two parameters should be optimized and furthermore balanced in order to promote sustainable electrocatalytic hydrogen production.

Fabrication of Superinsulating Poly(Urethane‐Isocyanurate) Aerogels Derived from Upcycled Polycarbonate

open access: yesAdvanced Sustainable Systems, EarlyView.
Bisphenol‐A polycarbonate is upcycled via a simple one‐pot reaction into an aromatic Mannich polyol, which serves as a precursor for fabricating poly(urethane‐isocyanurate) (PUR‐PIR) aerogels. PUR‐PIR aerogels, prepared with different isocyanate indices, exhibit high porosities, high specific surface areas, ultralow thermal conductivity, and excellent ...
