Stamp fabrication by step and stamp nanoimprinting: Dissertation
, 2011 The nanoimprinting is a potential method for submicron scale patterning for various applications, for example, electric, photonic and optical devices. The patterns are created by mechanical deformation of imprint resist using a patterned imprinting mold called also a stamp.

Advanced Materials, EarlyView.A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Advanced Materials, EarlyView.Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Advanced Materials, EarlyView.Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Mouler, tirer, modifier, mouler à nouveau. Rodin et le moulage
In Situ, 2016 In the context of an artist’s studio, the term ‘moulding’ (moulage) should be limited to the operation which involves making a mould. The object produced from this mould is a ‘proof’ or ‘test’ (épreuve), a stage, or the result in a process of creating a ...
