Application of flexible recipes for model building, batch process optimization and control [PDF]

open access: yes, 1993
Unlike the traditionally fixed recipes in batch process operation, flexible recipes allow the adjustment of some of its relevant recipe items. These adjustments can either be predefined in cases of planned experimentation, or suggested by a formal ...

Biphasic Ni‐MXene Quantum‐Confined Nanostructures: A Versatile Janus Platform for Advanced Energy Storage and Catalytic Oxidations

open access: yesAdvanced Materials, EarlyView.
A biphasic Ni‐MXene quantum‐confined nanostructure (Ni‐MJQD) serves as a Janus platform, simultaneously achieving high‐performance energy storage and efficient catalytic oxidation. The unique architecture enables superior energy storage performance and selective benzyl alcohol oxidation‐symbolizing “one stone, two birds” for sustainable energy and ...

Single‐Crystal Organic Field‐Effect Transistors Based on 5,15‐Bisaryl‐Tetrabenzoporphyrins: Synthesis, Structure, and Charge Transport Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...

The Role of Porosity in SERS

open access: yesAdvanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Review of Coherent Anti‐Stokes Raman Scattering Nonresonant Background Removal and Phase Retrieval Approaches: From Experimental Methods to Deep Learning Algorithms

open access: yesAdvanced Photonics Research, EarlyView.
Coherent anti‐stokes Raman spectroscopy (CARS) enables high‐resolution vibrational imaging, yet non‐resonant background (NRB) distorts spectral fidelity. This review highlights NRB removal methods—from experimental strategies and numerical algorithms to emerging deep learning techniques.

Gold‐Catalyzed Synthesis of Fluorenones via Intramolecular C–H Arylation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Starting from 2‐diazobenzophenones, a straightforward synthesis of valuable fluorenones via a gold‐catalyzed one‐pot oxidation, C–H activation, and cyclization is described. The addition of ascorbic acid, the correct selection of the counteranion of the 2‐diazobenzophenones, and the use of terpyridine as an auxiliary ligand are crucial for the reaction
