Is a Malleable Active Site Loop the Key to High Substrate Promiscuity? Hybrid, Biocatalytic Route to Structurally Diverse Taxoid Side Chains with Remarkable Dual Stereocontrol

open access: yesAngewandte Chemie, EarlyView.
A highly stereoselective, dynamic reductive kinetic resolution (DYRKR) entry into myriad Taxotere‐like side chains with Clostridium acetobutylicum alcohol dehydrogenase (CaADH) enzyme is reported. Follow‐on cross couplings expand the structural diversity of the library (36 total examples).

THE FIRST PRIVATIZATION POLICY IN A DEMOCRACY: SELLING STATE-OWNED ENTERPRISES IN 1948-1950 PUERTO RICO. [PDF]

open access: yes
In the 1940s, when the Governor of Puerto Rico was appointed by the US President and the Puerto Rican government was answerable only to the US Federal government, a large state-owned enterprise (SOE) sector was established on the island.

Electromagnetically Adhering and Self‐Inductive Sensing Claw for Continuum Climbing Robots: Design, Control, and Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
To argue the applicability of continuum wall‐climbing robots in the nuclear industry, an electromagnetic adhering and self‐inductive sensing integrated claw is developed. The flexible claw realizes an integrated design of the physical structure and excitation circuit. An automatic contact strategy based on fuzzy controller is established, which enables

Tuning Eley–Rideal Mechanism in Electrochemical Acetylene Semi‐Hydrogenation

open access: yesAngewandte Chemie, EarlyView.
The ER mechanism plays a vital role in electrocatalytic hydrogenation, yet its rate‐limiting factors remain poorly understood. Using acetylene hydrogenation as a model, we uncover atomic activation and spatial hindrance as key ER bottlenecks. Cu3Au, with balanced adsorption strength, exemplifies how introducing weak‐binding atoms into moderate‐binding ...
