Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups

open access: yesAdvanced Materials Technologies, EarlyView.
Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

Scale-up of microtechnology for fuel processing applications: comparison between fixed-bed and microchannel reactor systems

open access: yes, 2006
Microreactor (microchannel) technology and conventional (fixed-bed) reactor technology for the case of methanol fuel processing were studied. The microreactors were designed using dedicated microreactor models including heat conduction in the ...

Silk Fibroin Nanofiber–Immobilized Horseradish Peroxidase Enables Continuous Preparation of Injectable Hydrogels With Negligible Residual Enzyme for Drug Delivery

open access: yesAdvanced Materials Technologies, EarlyView.
Overcoming the immunogenicity challenges of enzyme‐mediated crosslinking, a flow‐through reactor utilizing SFNF‐HRP enables the continuous production of injectable hydrogels. This continuous platform ensures homogeneous crosslinking while minimizing residual HRP in the resulting hydrogels.

Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

open access: yesAdvanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

open access: yesAdvanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

open access: yesAdvanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Development and Application of Reactor Noise Diagnostics

open access: yes, 1999
A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple
