Bis‐Dichlorosilyl Functionalized C4‐Cumulene With Unique Bonding Scenario

open access: yesChemistry – A European Journal, EarlyView.
Herein, we report a silylene‐functionalized C4‐cumulene (2) and investigate its bonding scenario employing computational methods such as NBO analysis, AIM, and energy decomposition analysis‐natural orbital for chemical valence (EDA‐NOCV). The EDA‐NOCV analysis showed that compound 2 prefers to possess electron‐sharing covalent sigma and dative covalent

Sub-structural Niching in Estimation of Distribution Algorithms

open access: yes, 2005
We propose a sub-structural niching method that fully exploits the problem decomposition capability of linkage-learning methods such as the estimation of distribution algorithms and concentrate on maintaining diversity at the sub-structural level.

Denoising Autoencoders for fast Combinatorial Black Box Optimization

open access: yes, 2015
Estimation of Distribution Algorithms (EDAs) require flexible probability models that can be efficiently learned and sampled. Autoencoders (AE) are generative stochastic networks with these desired properties.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

open access: yesChemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...

Radical Stability Paradox: Substituent Effects versus Heats of Formation

open access: yesChemistry – A European Journal, EarlyView.
Rethinking molecular stability: Quantum‐chemical analyses show that the greater stability of tertiary over primary organic radicals is not caused by stabilizing substituent effects but by the inherent stability of the substituent. ABSTRACT Recently, we have shown that alkyl substituents destabilize the carbon radical center of organic radicals. However,
