Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

The effect of powder recycling in direct metal laser deposition on powder and manufactured part characteristics [PDF]

, 2006
A potential way of improving the material efficiency and cost effectiveness of the Direct Metal Laser Deposition (DMLD) process is to take powder that is not utilised in each deposition attempt and re-use it in subsequent attempts (powder recycling ...

Passively Q-switched nd:YAG laser via a WS2 saturable absorber

, 2016
In this work, we report a passively Q-switched Nd:YAG laser at 1064 nm by using WS2 solution as the saturable absorber (SA). The WS2 solution with different concentrations (0.25, 0.5, and 1 mg/ml) were fabricated by the liquid-phase-exfoliated method ...

Linking Pulse‐Duration‐Controlled Laser Nanostructuring to Oxygen Evolution Kinetics in Fe‐enriched NiOx Electrodes

Small, EarlyView.
Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Passive Q-switching in a diode-side-pumped Nd:YAG laser at 1.319 mu m

, 2013
We demonstrated a passively Q-switched Nd:YAG laser operating at 1.319 mu m using a transmission-type single-wall carbon nanotube (SWCNT) as the saturable absorber.
