Fluorescent Hydrogel‐Based Strain Sensor With Machine Learning‐Augmented Performance

open access: yesAdvanced Intelligent Discovery, EarlyView.
Fluorescent hydrogel strain sensor based on carbon quantum dots enabling optical readout of deformation through strain‐dependent emission changes, coupled with Random Forest analysis to capture nonlinear fluorescence‐concentration relationships and identify optimal sensing conditions. Hydrogels are ideal matrices for bio‐integrated wearable sensors due

[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides

open access: yesAngewandte Chemie, EarlyView.
The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Degradable Alternating Copolymers With Strained Cyclobutane Backbones via Photocontrolled RAFT Polymerization

open access: yesAngewandte Chemie, EarlyView.
A photocontrolled RAFT strategy enables the alternating copolymerization of 1,3‐disubstituted bicyclo[1.1.0]butanes with electron‐deficient comonomers, affording well‐defined copolymers bearing strained cyclobutane backbones. A high degree of alternation, tunable molecular weights, and excellent end‐group fidelity are achieved through a CTA‐mediated ...

Diagnóstico: la reforma tributaria y las políticas fiscales necesarias en el Perú. Entrevista a César Luna-Victoria León

open access: yesThēmis, 2013
The recollection in the Peruvian tax system has been a constant problem over the years, mainly due to the high degree of informality and tax avoidance. The tax reform implemented in 2012 aimed to find a solution to these problems, yet it didn’t embrace ...

Quantifying the Sites of Government, Commercial, and Personal Systems‐Perpetrated Financial Abuse

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This study explores the institutional systems through which post‐separation financial abuse is perpetrated. While existing measures seek to quantify the harms experienced by women post‐separation, this study draws on financial, welfare and legal service casefiles to identify where such harms occur. Drawing on 76 de‐identified Victorian service

Photometallobiocatalytic Asymmetric Radical‐Mediated Cross‐Coupling of Organotrifluoroborate Salts and Pyridotriazoles

open access: yesAngewandte Chemie, EarlyView.
An enantioselective photometallobiocatalytic cross‐coupling of pyridotriazoles and secondary alkyltrifluoroborate salts is developed. Cooperative catalysis using eosin B and an engineered protoglobin combines visible‐light‐mediated radical generation with enzymatic metal carbenoid activation, affording valuable N‐heterocyclic products in excellent ...

Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

Unraveling Terminal Cobalt–Antimony Double Bond: Breaking New Ground in Heavy Pnictogen Multiple Bonds

open access: yesAngewandte Chemie, EarlyView.
N‐heterocyclic carbenes (NHCs) function as “molecular scissors,” cleaving otherwise inert Sb═Sb bonds in distibenes to generate monomeric, zwitterionic stibinide species. These intermediates act as efficient stibinidene transfer reagents, granting access to a rare terminal cobalt–stibinidene complex.

Organocatalytic Enantioselective Addition of Malonates to Cyclic Imines: A Short Total Synthesis of Tetraponerine T‐1

open access: yesAngewandte Chemie, EarlyView.
A stereoselective functionalization method of cyclic imines under mild organocatalytic conditions was developed. Bifunctional cinchona alkaloid catalysts combined with carefully optimized reaction conditions to suppress background reactivity enabled highly enantio‐ and diastereoselective addition reactions of malonates to cyclic imines.
