1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides

open access: yesAdvanced Materials, EarlyView.
During MOCVD growth of MoS2 and WSe2, a transient metallic 1T phase emerges in early, edge‐rich, chalcogen‐deficient domains and declines as the films ultimately coalesce as 2H material. Together, experiments and ReaxFF simulations link domain size, edge stoichiometry, and vacancies to this evolution.

Regarding the discussion about the banded magnetic anomalies of the oceans

open access: yesГеофизический журнал
The author supports the theory of plate tectonics with a plume component, pointing out the weak aspects of the arguments regarding the banded magnetic anomalies (BMA) of the ocean floor, which are the subject of discussions between supporters and ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Scalable Production of Disordered Nickel‐Iron‐Aluminum Oxides as Stable Anodes for Water Electrolysis: The Role of Aluminum

open access: yesAdvanced Materials Interfaces, EarlyView.
Solution precursor plasma spraying enables the scalable fabrication of porous and disordered nickel‐iron‐aluminum oxide coatings as precious‐metal‐free anodes. Aluminum inhibits crystal growth, optimizes local atomic sites, and enhances charge and ion transport to accelerate reaction kinetics, leading to excellent performance and operational stability.

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

open access: yesAdvanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall

Atmospheric ice nuclei in the Eyjafjallajökull volcanic ash plume [PDF]

open access: yes, 2011
Explosive volcanism affects weather and climate. Primary volcanic ash particles which act as ice nuclei (IN) can modify the phase and properties of cold tropospheric clouds.

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

open access: yesAdvanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Innate Immunocompetent hiPSC‐Derived Neurospheroids Capture Early CNS Responses to rAAV

open access: yesAdvanced Science, EarlyView.
Knowledge of human CNS immune responses to AAV‐based gene therapies remains limited due to the lack of immune‐competent human models. Here, a hiPSC‐derived 3D neuroimmune platform integrating neurospheroids and microglia is established using stirred‐tank bioreactors.

Using synthetic oligonucleotides as standards in probe-based qPCR

open access: yesBioTechniques, 2018
Real-time PCR (qPCR) is widely used in the life sciences. For quantifying DNA, a standard curve is required. Common methods for standard development are time consuming, costly, necessitate a specific skill set, and pose a contamination risk.

Charting Endocrine Progenitors Across Species and Organs

open access: yesAdvanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.
