Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

Journal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

Small, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

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 ...

The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells

Small, EarlyView.
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.

Contactless Detection of Giant Helicity‐Dependent Photovoltage in Chiral 2D Perovskites

Small, EarlyView.
A novel contactless probe—circularly polarized time‐resolved surface photovoltage spectroscopy is demonstrated to evaluate helicity‐dependent charge separation dynamics without the need for electrical contacts. Application of this novel methodology to chiral 2D perovskites reveals giant transient surface photovoltage anisotropy.

[Au4(dppb)3]2+ – A Planar Gold Cluster with Bright Excitation Wavelength Dependent Emission

Small, EarlyView.
The first planar [Au4]2+ cluster with a deltoid geometry displays red to near‐infrared emission tunable from 700 to 918 nm. A quantum yield of 17% is observed at 770 nm upon 375 nm excitation. Excitation‐wavelength‐dependent shifts in emission reveal the involvement of multiple excited states, highlighting unprecedented photophysical versatility in ...
