Synthesis and Characterization of a Cerium(IV) Coordination Polymer Containing Isonicotinic Acid Zwitterions

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new coordination polymer [Ce4O2(OH)2(NO3)2(C6H5NO2)8](NO3)8 is reported. It was discovered during a ligand screening experiment. Its crystallization was studied in situ via powder X‐ray diffraction and X‐ray absorption near‐edge structure spectroscopy.

Factors Affecting the Color Change of Monolithic Zirconia Ceramics: A Narrative Review

Journal of Functional Biomaterials
Zirconia restorations are widely used in dentistry due to their high esthetic expectations and physical durability. However, zirconia’s opaque white color can compromise esthetics.

Interventional oncology in children: Where are we now?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

A Hybrid Approach Using AI‐Assisted Chairside Staining for an Anterior Metal‐Ceramic Crown

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To describe a hybrid approach for a metal‐ceramic anterior crown, combining traditional ceramic layering with a chairside staining technique guided by recipes generated using an artificial intelligence‐based software. Clinical Considerations The clinical case presented a step‐by‐step protocol from both laboratory and clinical ...

Template effect in the synthesis of micro- and nanoscale oxide materials and compositions based on them in combustion reactions of glycine-nitrate precursors

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов
It is evident from the extant results of experimental studies that the possibility of the manifestation of the template effect in the formation of anisometric micro- and nanoscale formations in oxide and composite systems has been analysed.

Effect of Occlusal Adjustment and Subsequent Repolishing on the Translucency Parameter, Contact Angle, and Flexural Strength of Different Types of Glazed Monolithic Zirconia

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of material and surface condition (glazed vs. polished after simulated occlusal adjustment) on translucency parameter, contact angle, and flexural strength of four monolithic zirconia. Materials and Methods Disk‐shaped specimens (n = 80, Ø12 × 1 mm) were fabricated from four monolithic zirconia ...

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

Divergent Phosphorus‐Mining Strategies in Simple and Compound Cluster Roots in Extremely Phosphorus‐Impoverished Soils in Southwest Australia

Plant, Cell &Environment, EarlyView.
ABSTRACT Most Proteaceae and some Fabaceae species produce specialised cluster roots (CRs), and are abundant in severely phosphorus (P)‐impoverished soils in southwest Australia. Two types of CRs, compound and simple, have been identified. However, the difference in their P‐mining strategies remains unclear. Therefore, we conducted glasshouse and field
