Learning Moisture‐Induced Damage From Vision: Diffusion Models for Real‐Time Monitoring of Additive Manufacturing Processes

Advanced Science, EarlyView.
We introduce a vision‐based real‐time monitoring system for additive manufacturing that detects subtle moisture‐induced degradation via a diffusion model‐based framework. The approach enables nondestructive assessment of moisture‐induced damage level and mechanical performance and establishes a practical route toward more intelligent, reliable, and ...

Dicer-TRBP Complex Formation Ensures Accurate Mammalian MicroRNA Biogenesis

, 2015
RNA-mediated gene silencing in human cells requires the accurate generation of ∼22 nt microRNAs (miRNAs) from double-stranded RNA substrates by the endonuclease Dicer.

Real‐Time Ferroelectric Domain Wall Dynamics During Electric Poling and Depoling

Advanced Science, EarlyView.
Real‐time visualization of domain wall dynamics during alternating‐current poling, direct‐current poling, and electrical depoling in relaxor‐PT ferroelectric single crystals reveals distinct field‐dependent pathways and strong path dependence. Instant polarized light microscopy uncovers reversible domain wall nucleation, motion, and reconfiguration ...

Covalently Integrated Selenoviologen–N‐Heterocyclic Carbene–Pt Nanoparticles for Visible‐Light‐Driven Hydrogen Evolution

Advanced Science, EarlyView.
A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Substrate-specific structural rearrangements of human Dicer [PDF]

, 2013
Human Dicer can process long double-stranded RNA and hairpin precursor RNA to yield short interfering RNAs or microRNAs, respectively. EM and single-particle analyses of Dicer–substrate complexes now provide insight into the structural basis of Dicer's ...

Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

Advanced Science, EarlyView.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

Upregulation of PHLDA2 in Dicer knockdown HEK293 cells

, 2007
It has been reported that RNAi-dependent chromatin silencing in vertebrates is not restricted to the centromeres. To address whether RNAi machinery could regulate the chromatin structure of imprinted genes, we knocked down Dicer in HEK293 cells and found

Cleavage of Dicer protein by I7 protease facilitates Dicer degradation.

, 2015
(A) HeLa cells were mock-transfected (lane 1), co-transfected with the plasmids expressing T7-Dicer and empty vector (lanes 2 and 4) or the plasmids expressing T7-Dicer and I7 protease with V5 tag (lanes 3 and 5). Thirty-two hrs after transfection, 10 uM

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

Advanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Dicing the Disease with Dicer: The Implications of Dicer Ribonuclease in Human Pathologies

, 2020
Gene expression dictates fundamental cellular processes and its de-regulation leads to pathological conditions. A key contributor to the fine-tuning of gene expression is Dicer, an RNA-binding protein (RBPs) that forms complexes and affects transcription
