Compiling the national accounts demystified [PDF]

This paper unveils the mystery of national accounts statistics. National accounts statistics are not facts. They are estimates of a universal accounting model (SNA93) for describing, analyzing and managing national economies.

Influence of Impurities on the Electrochemical Upcycling of Biomass

ChemSusChem, Volume 19, Issue 4, 25 February 2026.
5‐hydroxymethyl furfural (HMF) and furfural contain impurity levels that lie below the detection limit of common analysis techniques. Yet, these impurity levels have an adverse effect on the electrochemical conversion of these compounds. In this study, we show that distillation of furfural and recrystallization of HMF facilitates their electrochemical ...

Constraint-Based Categorial Grammar

, 1994
We propose a generalization of Categorial Grammar in which lexical categories are defined by means of recursive constraints. In particular, the introduction of relational constraints allows one to capture the effects of (recursive) lexical rules in a ...

Scalable, Bottom‐Up Synthesis of Transition Metal–Doped Quantum Confined, 1D Titanate‐Based Lepidocrocite Nanofilaments, Their Electronic Structures and Oxygen Evolution Reactivity

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Quantum‐confined lepidocrocite titanate nanofilaments are doped, bottom‐up, with Mn+2, Fe+2, Co+2, Ni+2, and Cu+2 to tune electronic structure and catalysis. Doping narrows the bandgap—by up to ∼0.8 eV—and extends visible absorption. Ni‐doped filaments accelerate oxygen evolution (319 mV at 10 mA cm−2) and TM‐doped samples rapidly degrade rhodamine 6G (

Engineering a Perfusion Bioreactor System for hiPSC‐Derived Progenitor Co‐Culture Capturing Microglial Features in CNS Development

Biotechnology and Bioengineering, Volume 123, Issue 2, Page 363-378, February 2026.
The authors report the development of a controlled and scalable 3D co‐culture system combining hiPSC‐derived erythromyeloid progenitors and neurospheres within the Ambr® 250 Modular platform operated with a newly designed perfusion system. This model faithfully recapitulates early microglia–neural interactions, enabling progenitor integration ...

Evaluation of Process Parameters for Integrated CO2 Electrolysis to Produce Ethylene

ChemistryOpen, Volume 15, Issue 2, February 2026.
This work systematically explores how flow rate, pressure, and temperature influence ethylene selectivity in integrated CO2 electrolysis with a potassium carbonate absorbent. Findings reveal that higher catholyte flow rates improves Faraday efficiency for ethylene by overcoming mass transport barriers, while increased pressure or temperature does not ...

On‐Resin Pictet–Spengler Cyclization for 1,2,3,4‐Tetrahydro‐β‐carboline‐3‐carboxylate (Tcc) Peptide Synthesis With Acid‐Labile Functional Tolerance

Journal of Peptide Science, Volume 32, Issue 2, February 2026.
The constrained tryptophan (Trp) analog 1,2,3,4‐tetrahydro‐β‐carboline‐3‐carboxylic acid (Tcc) is used to restrict peptide conformation in structure–activity relationship studies. Although Pictet–Spengler cyclization of Trp and aldehydes with mineral acid gives Tcc analogs, such harsh conditions do not tolerate acid‐labile functionality.
