Substrate‐Selective Temperature‐Controlled Synthesis of Thiophene Derivatives at Interfaces
Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.The deposition of a dithiophene derivative on Ag(111) at room temperature followed by annealing gives rise to molecular wires, whereas the adsorption of the same precursor on a hot substrate affords the formation of benzotrithiophene species. Abstract The temperature‐controlled transformation of organic molecules at interfaces is an incipient yet ...

Kontsevich's conjecture on an algebraic formula for vanishing cycles of local systems
, 2013 For a local system and a function on a smooth complex algebraic variety, we give a proof of a conjecture of M. Kontsevich on a formula for the vanishing cycles using the twisted de Rham complex of the formal microlocalization of the corresponding locally

A Comprehensive Study of Dynamic Recrystallization Behavior of Mg Alloy with 3 wt.% Bi Addition
Metals, 2021 The effect of the addition of bismuth on the dynamic recrystallization (DRX) behavior of the matrix has been investigated by comparing coarse grain pure Mg with the addition of 3 wt.% Bi, using a uniaxial compression test in the temperature range of 473 ...

Directional‐DRX for 5G wireless communications
Electronics Letters, 2016 Directional‐discontinuous reception (D‐DRX) is proposed for millimetre‐wave enabled fifth‐generation communications. In addition to conventional active, short‐sleep and long‐sleep states, the proposed mechanism considers a separate beam searching state, to address alignment of directional beams between user equipment (UE) and evolved node B after a ...

Diffusive Mobile Molecular Communications Over Time-Variant Channels
, 2017 This letter introduces a formalism for modeling time-variant channels for diffusive molecular communication systems. In particular, we consider a fluid environment where one transmitter nano-machine and one receiver nano-machine are subjected to Brownian
