Synthesis and Structure of Neopentyl Sodium: A Hydrocarbon‐Soluble Reagent for Controlled Sodiation of Non‐Activated Substrates

open access: yesAngewandte Chemie, EarlyView.
Displaying strong controlled metalating power, hydrocarbon‐soluble sodium neopentyl can deprotonate challenging non‐activated arenes and alkenes, with sodiated intermediates successfully undergoing onward functionalisation reactions. By characterising key reaction intermediates, and running computational studies on models, insight has been gained on ...

Formation stage and controlling factors of the paleo-uplifts in the Tarim Basin: A further discussion

open access: yesNatural Gas Industry B, 2016
Various types of paleo-uplifts with different characteristics are developed in the Tarim Basin. Previously, there were multiple opinions on the pale-uplifts origins and structural evolution, so the oil and gas exploration ideas and deployment in the ...

Hydrological Interpretation of Basin Morphology [PDF]

open access: yes, 1978
Completion Report OWRT Agreement No. 14-31-0001-5002 OWRT Project A-049-ALASHydrologic processes in a particular basin are governed by three groups of factors: input regimes of mass and energy, the nature of mass and energy transfer and ...

Amyloid Forming Human Lysozyme Intermediates are Stabilized by Non‐Native Amide‐π Interactions

open access: yesAdvanced Science, EarlyView.
Mutational variants of human lysozyme cause fatal systemic amyloidosis by depositing kilograms of protein in the viscera of patients. Central to this process is a partially unfolded protein intermediate state that initiates aggregation into amyloid fibrils.

On the origin of the North Pacific arcs [PDF]

open access: yes, 2004
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

open access: yesAdvanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

open access: yesAdvanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed
