Facile One-Pot Assembly of Push-Pull Imines by a Selective C-F Substitution Process in Aryl Fluorides

Herein, we report the synthesis of a series of push-pull imines by considering cyclic diamino substituent at the C-centre and fluoroaryl substituent at the N-centre. This has been achieved by a selective aromatic nucleophilic substitution of different fluo ...

Computational Modeling of the Oxygen Evolution Reaction at Semiconductor-Water Interfaces: A Path Towards Breaking Linear Scaling Relationships

Patrick Gono

Photoelectrochemical water splitting is a promising source of clean, renewable fuel in the form of hydrogen. Despite extensive research endeavors, the widespread adoption of this technology is impeded due to suboptimal catalysts for the oxygen evolution re ...

Characterising Structure and Stability of Materials using Machine Learning

Andrea Anelli

The search of novel materials using in-silico high-throughput screening is emerging as a fundamental step in the pipeline of materials discovery, but its low yields in terms of synthesisable structures limit its effectiveness. In order to isolate configura ...

Classical Misuse Attacks on NIST Round 2 PQC: The Power of Rank-Based Schemes

Serge Vaudenay, Loïs Evan Huguenin-Dumittan

The US National Institute of Standards and Technology (NIST) recently announced the public-key cryptosystems (PKC) that have passed to the second round of the post-quantum standardization process. Most of these PKC come in two flavours: a weak IND-CPA vers ...

Hybrid granular hydrogels: combining composites and microgels for extended ranges of material properties

Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss

Developing hydrogels with optimal properties for specific applications is challenging as most of these properties, such as toughness, stiffness, swelling or deformability, are interrelated. The improvement of one property usually comes at the cost of anoth ...

Stabilization of the Oxidation State plus IV in Siloxide-Supported Terbium Compounds

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

The synthesis of lanthanides other than cerium in the oxidation state +IV has remained a desirable but unmet target until recently, when two examples of Tb-IV with saturated coordination spheres were isolated. Here we report the third example of an isolate ...

Copper-Catalyzed 1,2-Methoxy Methoxycarbonylation of Alkenes with Methyl Formate

Qian Wang, Jieping Zhu, Alexandre Julien Florent Leclair, Balázs Budai

Reported here is a copper-catalyzed 1,2-methoxy methoxycarbonylation of alkenes by an unprecedented use of methyl formate as a source of both the methoxy and the methoxycarbonyl groups. This reaction transforms styrene and its derivatives into value-added ...

Unexpected Indirect Dynamics in Base-Induced Elimination

Eduardo Carrascosa Casado

Base-induced elimination (E2) and bimolecular nucleophilic substitution (S(N)2) are two of the most versatile reactions that are important in preparative organic chemistry. These stereospecific reactions are often found in direct competition with each othe ...
