Analysis of Machinability on Properties of Inconel 718 Wire and Arc Additive Manufacturing Products

open access: yesJournal of Manufacturing and Materials Processing, 2023
Wire and arc additive manufacturing (WAAM) is a metal deposition technique with a fast rate and the possibility of a high volume of deposition. Because of its fast deposition and high heat input, the manufactured products have poor surface quality.

Distance dependence of force and dissipation in non-contact atomic force microscopy on Cu(100) and Al(111) [PDF]

open access: yes, 2004
The dynamic characteristics of a tip oscillating in the nc-AFM mode in close vicinity to a Cu(100)-surface are investigated by means of phase variation experiments in the constant amplitude mode.

Influences of Material Selection, Infill Ratio, and Layer Height in the 3D Printing Cavity Process on the Surface Roughness of Printed Patterns and Casted Products in Investment Casting

open access: yesMicromachines, 2023
As 3D-printed (3DP) patterns are solid and durable, they can be used to create thin wall castings, which is complicated with wax patterns because of the wax’s fragility and high shrinkage ratio.

Evidence from scanning tunneling microscopy in support of a structural model for the InSb(001)-c(8×2) surface [PDF]

open access: yes, 1999
In this letter we present evidence from scanning tunneling microscopy studies in support of a recently proposed structural model for the indium-terminated c(8×2) surface of InSb(001). This structural model, by Norris and co-workers, is based on a surface

Surface-mode microcavity

open access: yes, 2005
Optical microcavities based on zero-group-velocity surface modes in photonic crystal slabs are studied. It is shown that high quality factors can be easily obtained for such microcavities in photonic crystal slabs.

On the Mechanism of the Step Coverage of Blanket Tungsten Chemical Vapor Deposition [PDF]

open access: yes, 1993
In this study, computer modeling of the contact fill process with chemical vapor deposition, (CVD) of tungsten is usedto show the importance of several details on the quality of the fill process. The effect of surface curvature on the stepcoverage of CVD-

CPX‐351 in High‐Risk Relapsed Pediatric Acute Leukemia: Real‐World Phase 1 Data Establishing the FDA‐Approved Dose

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Outcomes for pediatric relapsed/refractory (R/R) acute myeloid leukemia (AML) remain dismal. CPX‐351, a liposomal formulation of cytarabine and daunorubicin, may have less off‐target toxicities than traditional chemotherapies and has shown improved outcomes for adults with newly diagnosed therapy‐related AML.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
