Multispectral Concentric Grafted Perfect Vector Vortex Beam

open access: yesLaser &Photonics Reviews, EarlyView.
Multispectral structured light offers powerful opportunities for increasing information capacity. A multispectral concentric grafted perfect vector vortex beam is proposed to engineer topological charges and polarization. A metasurface can graft different perfect vector vortex beams across concentric spatial regions and extend this concept to ...

Polymethyl – Methacrylate Implants in Forehead and Supraorbital Arches Reconstruction: Retrospective Study

open access: yes, 2001
Frontobasal injuries and some other diseases of frontal sinuses sometimes require radical surgery with the obliteration of the sinus. A cosmetic correction of the forehead and supraorbital arches has to be performed after such a procedure.

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

Memristors Based on Ferroelectric Cu‐Deficient Copper Indium Thiophosphate for Multilevel Storage and Neuromorphic Computing

open access: yesSmall, EarlyView.
Different from CIPS with threshold switching behaviors, Cu‐deficient CIPS* shows stable non‐volatile digital and analog RS. Owing to the formation of metallic IPS at the LRS, CIPS* memristors demonstrate high ON/OFF ratio and endurance stability, which can be utilized to implement multilevel storage.

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

open access: yesSmall, 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 ...

Data for: Stable Isotope and Compositional Analysis of Alaska Caribou Teeth Embedded in Polymethyl-methacrylate (PMMA)

open access: yes
This is data on the impact of embedding modern caribou (Rangifer tarandus) teeth in the polymer polymethyl-methacrylate on stable carbon and nitrogen isotopes, as well as the efforts to mitigate that impact through acetone baths and acetone baths with ...

Exploiting Device Deformability for Fluid and Particle Manipulation

open access: yesSmall, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Accurate Sizing and Resolution of Nominal 200 nm Diameter Polystyrene Nanospheres With Charge Detection Mass Spectrometry

open access: yesSmall, EarlyView.
This study highlights the utility of charge detection mass spectrometry (CDMS) as a high‐throughput nanoparticle characterization tool. CDMS measurements of 200 nm polystyrene size standards are within 1% of those derived from transmission electron microscopy (TEM). Notably, a mixture of three ∼200 nm samples is readily resolved by CDMS but not by TEM,

Interfacial Regulation–Driven Dual‐Enrichment SERS Coupled With Deep Learning Enable Ultrasensitive and In Situ Identification of Microplastics in Natural Waters

open access: yesSmall, EarlyView.
A membrane‐confined SERS platform constructs a dense network of vertical hotspots using PSS‐Na‐modified Au@Ag nanocubes for sensitive and reproducible microplastic detection in complex environmental water matrices. Coupled with an attention‐based 1D‐CNN, it enables accurate polymer identification and semi‐quantitative mixture prediction for intelligent
