Modified Neumann incision for implant placement in overdentures: Case series of a less invasive alternative

Clinical Advances in Periodontics, EarlyView.
Abstract Background Conventional envelope flap techniques for implant placement in edentulous mandibles are associated with greater postoperative morbidity, especially in elderly patients or those with anatomical limitations. Minimally invasive alternatives aim to preserve soft tissues and reduce complications, enhancing clinical predictability ...

Investigating graviton mass effects on black hole lensing in dRGT massive gravity

European Physical Journal C: Particles and Fields
In this paper, we delve into the gravitational lensing and photon trajectories in the vicinity of non-asymptotically flat black hole within the framework of de Rham–Gabadadze–Tolley (dRGT) massive gravity, incorporating a non-zero graviton mass.

Acceleration-induced transport of quantum vortices in joined atomtronic circuits

SciPost Physics
Persistent currents–inviscid quantized flow around an atomic circuit–are a crucial building block of atomtronic devices. We investigate how acceleration influences the transfer of persistent currents between two density-connected, ring-shaped atomic Bose-

Establishing Indium in Frustrated Lewis Pair Chemistry: From Synthesis to Catalytic Applications

ChemistryEurope, EarlyView.
Not that hard: The effects of chemical hardness of the soft FLP tBu2InCH2PtBu2 and its pyridine‐adduct tBu2In(py)CH2PtBu2 were examined in adduct formation reactions toward H2, CO2, and CS2. The frustrated Lewis pair shows catalytic activity in the reduction of CO2 with pinacolborane.

Optical+Near-IR Analysis of a Newly Confirmed Einstein Ring at z ∼ 1 from the Kilo-Degree Survey: Dark Matter Fraction, Total and Dark Matter Density Slope, and Initial Mass Function

The Astrophysical Journal Letters
We report the spectroscopic confirmation of a bright blue Einstein ring in the Kilo-Degree Survey (KiDS) footprint: the Einstein “blue eye.” Spectroscopic data from X-Shooter at the Very Large Telescope (VLT) show that the lens is a typical early-type ...

Quantum Chemistry Investigation of Linear and Nonlinear (chir)optical Properties of Oligoamide Foldamers

ChemistryEurope, EarlyView.
The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Functionalized Organic Lithium Salt Enables Flexible Solid‐State Electrolytes With Dual‐Ion Channels for Safe Li Metal Batteries

Carbon Energy, EarlyView.
Here, we design a flexible and non‐flammable solid‐state electrolyte with hierarchical dual‐ion conductive channels. The engineered electrolyte combines continuous organic conductive‐phase pathways for fast bulk Li+ transport and dynamic polymer networks for interfacial ion hopping, achieving unprecedented room temperature conductivity (> 1 mS cm−1 ...

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

Carbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio

Chemie Ingenieur Technik, EarlyView.
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

How Amino Acids Intercalate in CaFe Layered Double Hydroxides: A Combined RIXS and NEXAFS Study

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Intercalation of amino acids in layered double hydroxides offers a road to functional (bio)catalysts. With resonant soft x‐ray spectroscopy we probe the electronic structure of these systems and observe activation and passivation of electronic states as well as bond formation between the amino acid and the LDH upon intercalation.
