Active Metal Template Synthesis of Rotaxanes From BINOL‐Phosphate Macrocycles

Angewandte Chemie, EarlyView.
The use of macrocyclic BINOL‐phosphates allows for the active metal template synthesis of [2]rotaxanes via Cu(I)‐mediated alkyne‐azide cycloaddition. DFT calculations, control experiments, and kinetic experiments support a dinuclear phosphate‐Cu2 intermediate.

Lumped modeling of bubbling fluidized beds for high‐temperature processes

AIChE Journal, EarlyView.
Abstract Bubbling fluidized beds (BFBs) have been a source of study for multiple decades. Among other applications, they can be used as scalable reactors for the conversion of biomass and waste resources to fuels. Several experimental and computational studies have been devoted to correlating the interplay of hydrodynamics and heat and mass transfer in

Breakthrough Design of Highly Potent Antivirals Against Wild‐Type HIV‐1 and Lenacapavir‐Resistant M66I Variant

Angewandte Chemie, EarlyView.
Lenacapavir, the first‐in‐class drug targeting HIV‐1 capsid, is a breakthrough drug in HIV‐1 treatment and prophylaxis. However, a single M66I mutation confers complete viral resistance to lenacapavir. We report herein the design and synthesis of innovative R2 analogs demonstrating low nM potency against HIV‐1 M66I and excellent pharmacokinetics in ...

Reduction of methane emission from landfills using bio-mitigation systems – from lab tests to full scale implementation [PDF]

, 2014
Landfills are significant sources of methane, which contributes to climate change. As an alternative to mitigation by gas utilization systems, bio-mitigation systems may be implemented.

Enhanced biogas production via dual‐layer model predictive control for thermophilic anaerobic digesters

AIChE Journal, EarlyView.
Abstract Thermophilic anaerobic digestion (AD) is an attractive process due to its higher biogas yield compared to mesophilic digestion. To mitigate its higher heating demand and potential process instability, a dual‐layer control architecture comprising a decision‐making layer and an adaptive model predictive control (MPC) system is proposed.

Guest Transition Metals in Host Keplerate Nanocapsules as Supramolecular Inorganic Functional Mimics of Monooxygenase Enzymes

Angewandte Chemie, EarlyView.
A Keplerate, an inorganic, porous buckyball was used as a host for copper metal cations ligated by histidine surrogates. Prepared by a simple assembly technique, the guest–host complex was used as a primitive biomimetic model of a monooxygenase enzyme complex, where C─H bonds were electrocatalytically hydroxylated by oxygen under reducing conditions ...

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

Policy uncertainty shocks and farm investments in Europe: Evidence from a newspaper‐based index

American Journal of Agricultural Economics, EarlyView.
Abstract In order to quantify the impact of agricultural policy uncertainty on European farmers' investment behavior, we construct a newspaper‐based monthly index of European agricultural policy uncertainty from 2013 to 2023. We use 327,224 newspaper articles to assess and compare the trends in policy uncertainty across five top agricultural producers ...

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp3 Hybridization

Angewandte Chemie, EarlyView.
A new carbon allotrope with mixed sp–sp3 hybridization has been synthesized through delicately controlled kinetics at a liquid–liquid interface. The resulting material, termed diamondiyne, exhibits an expanded diamond‐type network in the form of small crystallites in a continuous all‐carbon film.
