Effect of Er:YAG Laser Irradiation on the Flexural Fatigue Strength of a 4YSZ Ceramic

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT This study aimed to evaluate the effect of Er:YAG laser surface treatment on the flexural fatigue strength of 4YSZ ceramics, with or without resin cement application. Disk‐shaped zirconia ceramic specimens (Ø = 15 mm, thickness = 1.2 mm of IPS e.max ZirCAD MT BL) were prepared and randomly assigned to 10 groups based on two factors: “surface ...

Advanced Tissue Imprinting With Pneumatic Press for Mass Spectrometry Imaging of Plant Tissues

Journal of Mass Spectrometry, Volume 61, Issue 1, January 2026.
ABSTRACT Sample preparation is an important first step to obtain high quality mass spectrometry imaging (MSI) data. Preparing plant tissues is especially challenging for MSI of thin tissues along the lateral dimensions. The unique challenges involved with plant tissues, such as fragile cell walls, hydrophobic barriers, and specific tissue structures ...

The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

Journal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

Intensification of the Southern Hemisphere westerly winds during the last deglaciation (18.5–14.0 cal ka BP): Evidence from Pearly Beach wetland on the southern Cape coast of South Africa

Journal of Quaternary Science, Volume 41, Issue 1, Page 25-35, January 2026.
ABSTRACT The southwestern Cape of South Africa experiences a complex and dynamic climate, shaped by the interplay between the temperate Southern Hemisphere westerly winds and the subtropical easterlies. Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response

Reversal Asymmetry of Reciprocal Metasurface Enables Ultra‐Compact Varifocal Reflective Lens

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
The possibility of breaking the reversal symmetry of a lens without violating reciprocity is demonstrated. The freedom provided is utilized to realize an ultra‐compact reflective varifocal lens‐doublet based on a flat metasurface lens and a piezoelectric actuated micromirror.

Olivine Deformation: To B Slip or Not to B Slip, That Is the Question

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract When deformed by dislocation creep the dominant slip (Burgers) vectors of olivine dislocations are parallel to [100] or [001]. Dislocations with an [010] Burgers vector component (b dislocations) have been recorded rarely. Here we show an experimentally deformed olivine sample has a substantial population (17%) of b dislocations.
