Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

X-Ray Spectrometry, Volume 55, Issue 3, Page 443-453, May/June 2026.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.

Impact of Mantle Velocity Uncertainty on Receiver‐Function Imaging of the Transition Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Seismological estimates of the 400‐km and 670‐km mantle discontinuities (d400 and d670) are crucial for understanding the thermochemical structure and dynamics of the mantle transition zone (MTZ). However, artifacts from using ray theory and uncertainties in mantle velocity structure can affect topographic mapping of these boundaries.

IMPROVEMENTS OF THE DIVIDE AND SEGMENT METHOD FOR PARALLEL IMAGE SEGMENTATION

Revista Brasileira de Cartografia, 2018
Remote Sensing is an important source of data about the dynamics of Earth's land and oceans, but retrieve information from this technique, is a challenge. Segmentation is a traditional method in remote sensing, which have a high computational cost.

3D‐Printed Geopolymer as a Basic Heterogeneous Catalyst for the Synthesis of α‐Cyanoacrylates Through the Knoevenagel Condensation

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.

Understanding Oxide Surface Stability: Theoretical Insights From Silver Chromate

Advanced Physics Research, Volume 5, Issue 4, April 2026.
Seven low‐index Miller surfaces, comprising 46 distinct terminations, were systematically investigated to determine their surface free energies as functions of the chemical potentials of the system constituents. The competition among these terminations gives rise to temperature‐dependent stability crossovers that dynamically reshape the surface energy ...

Ensemble Docking of FDA‐Approved and Peruvian Phytochemicals Against Monkeypox Virus Telomere‐Binding Protein

ChemistrySelect, Volume 11, Issue 9, 5 March 2026.
ABSTRACT Monkeypox is a reemerging zoonotic disease that has been spreading worldwide. Different approaches are being conducted to find effective treatments for this disease. To accelerate therapeutic discovery, we propose telomere‐binding protein (TBP) as a potential drug target because of its important role during virus maturation.
