Lipopolysaccharide-specific acyloxyacyl hydrolase [PDF]

open access: yes, 1991
" An acyloxyacyl hydrolase from the human promyelocyte cell line HL-60 has been found to specifically hydrolyze fatty acids from their ester linkages to hydroxy groups of 3-hydroxyfatty acids, the latter being being bound in turn to lipopolysaccharide ...

Electrochemical Dehydration of Carboxamides to Their Nitriles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
Electrochemical dehydration of carboxamides to nitriles is achieved using thiocyanate‐mediated activation, avoiding stoichiometric reagents. In an undivided cell at ambient conditions, 18 aromatic and aliphatic substrates give good‐to‐excellent yields (up to 84%) with functional‐group tolerance. Cyclic voltammetry supports an EC‐type‐mediated oxidation.

Potassium Thiocyanate‐Assisted Enhancement of Slot‐Die‐Coated Perovskite Films for High‐Performance Solar Cells

open access: yesSmall Science, 2021
Slot‐die coating is highly promising for scaled deposition of metal halide perovskite thin films. However, the power conversion efficiencies (PCEs) of slot‐die‐prepared perovskite solar cells (PSCs) still lag behind their spin‐casted counterparts.

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Novel expression of Haemonchus contortus vaccine candidate aminopeptidase H11 using the free-living nematode Caenorhabditis elegans [PDF]

open access: yes, 2013
With the problem of parasitic nematode drug resistance increasing, vaccine development offers an alternative sustainable control approach. For some parasitic nematodes, native extracts enriched for specific proteins are highly protective.

ENHANCED METHOD FOR AMPLIFYING ANTIMICROBIAL ACTIVITY OF LACTOPEROXIDASE SYSTEM IN MILK AND DERIVED PRODUCTS BY CARROT EXTRACT AND BETA CAROTENE [PDF]

open access: yes, 2014
OSCN–  has  been  known  and  well  documented  as  natural  antimicrobial  agent    generated  from the  lactoperoxidase  system (LPOS)  but  the  antimicrobial  activity  exerted  from  this  system  is  too  low  for  certain  food  such  as  milk ...

Influence of Metal Species and Content of Fe‐Ni‐Poly(heptazine imides) on their Properties as Electrocatalysts for Zinc‐Air Batteries

open access: yesAdvanced Energy Materials, Volume 16, Issue 11, 18 March 2026.
Iron/nickel‐modified poly(heptazine imides) are efficient, low‐cost bifunctional electrocatalysts for the oxygen reduction and evolution reactions in aqueous zinc–air batteries. Iron enhances oxygen reduction, while nickel single‐atoms deliver oxygen evolution activity comparable to RuO2.

CO2 Electroreduction to Multicarbon Products in Acidic Electrolyte via Structural Reconstruction of a Molybdenum Porphyrin Dimer

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
A novel oxo‐bridged molybdenum porphyrin dimer electrocatalyst undergoes potential‐driven structural reconstruction in acidic electrolyte, forming MoMo bonded active sites. This dynamic transformation enables selective electrochemical CO2 reduction to multicarbon products: methanol with 74% Faradaic efficiency at −1.0 V versus RHE, and ethanol with 45%

Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

open access: yesAnalysis &Sensing, Volume 6, Issue 2, March 2026.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.
