Cyber-attacks and stock market activity

open access: yesInternational Review of Financial Analysis, 2018
I study how financial markets react to unexpected corporate security breaches in the short and the long-term. The main results show that daily excess returns drop, trading volume increases due to selling pressure, and liquidity improves upon the public disclosure of first-time corporate hacking events.

Single‐Step Conversion of Metal Impurities in CNTs to Electroactive Metallic Nitride Nanoclusters for Electrochemical CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step, low‐temperature co‐pyrolysis process removes encapsulated seed metal NPs (10–50 nm) from CNTs, redistributing them as surface‐anchored metal and metal–nitride NCs (1–1.5 nm). Herein, Ni3N NCs achieve an ultra‐low onset overpotential for CO2 reduction to CO with >98% Faradaic efficiency across 100–700 mA cm−2.

Built‐In Electric Field in 2D/2D LDH/Antimonene Heterostructure to Induce Stable β‐NiOOH at Ultralow Potential for Cost‐Effective Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
In this paper, a built‐in electric field (BEF) strategy is proposed to fabricate NiFe‐LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The formed BEF generates a local potential that reduces the potential for the formation of β‐NiOOH, thereby enabling ultra‐low ...

Vat Photopolymerization of High Molecular Weight Polymer Latexes with Pseudothermoplastic Properties for Recyclability

open access: yesAdvanced Functional Materials, EarlyView.
A photocurable latex system enables high‐resolution vat photopolymerization of water‐dispersed thermoplastics, yielding pseudothermoplastic materials with recyclability. The formulation permits precise control over mechanical properties and supports reprocessing through conventional and extrusion‐based methods. Compatibility with two‐photon 3D printing
