Ultra‐Durable Information‐Encoded Anti‐Counterfeiting Self‐Assembled Nanocrystal Labels
Advanced Optical Materials, EarlyView.Ultra‐durable cost‐effective information‐encoded anti‐counterfeiting labels are fabricated to secure semiconductor chips. A novel method is used to self‐assemble colloidal quantum wells (CQWs) into color bars. Information can be encoded spatially, spectrally, and opto‐spatially.

Histopathologic Study of Caries at the Full and Partial Crowns Finish Line
Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2010 BACKGROUND AND OBJECTIVE: The cast crowns replace lost tooth structure. Probably, recurrent caries occurs at the preparation margins and give rise to crown failure, affected by several factors, such as dental prosthesis design.

Advanced Synthesis &Catalysis, EarlyView.Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic

Sialic Acid Sensing via Molecularly Imprinted Polymer on Laser‐Induced Graphene
Advanced Sensor Research, EarlyView.Sialic acid is an important biomarker for oral and overall health. Salivary levels of sialic acid are linked with oral cancer and other diseases. We develop a point‐of‐care sensor for sialic acid, based on molecularly imprinted aminophenylboronic acid electropolymerized onto laser‐induced graphene.

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades
Advanced Science, EarlyView.This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.
