Performance of Modified Natural Zeolites by Sodium Hydroxide Treatments in The Esterification of Glycerol and Oleic Acid

open access: yesJurnal Kimia Valensi, 2019
Esterification is the reaction of the formation of an ester compound by reacting an alcohol compound and carboxylic acid. In this study, the performance of zeolite-based catalysts has been studied for esterification reactions.

Restriction of the Conformational Dynamics of the Cyclic Acyldepsipeptide Antibiotics Improves Their Antibacterial Activity [PDF]

open access: yes, 2014
The cyclic acyldepsipeptide (ADEP) antibiotics are a new class of antibacterial agents that kill bacteria via a mechanism that is distinct from all clinically used drugs. These molecules bind and dysregulate the activity of the ClpP peptidase.

Hydrodeoxygenation and hydroisomerization of palm fatty acid distillate to green diesel using a NiWNb catalyst supported by natural zeolite: Insight into W concentration and process conditions

open access: yesSouth African Journal of Chemical Engineering
The production of renewable energy, such as green diesel from non-edible feedstocks such as palm fatty acid distillate (PFAD) represents a strategic approach to addressing the energy transition.

Enhancing Synaptic Plasticity and Multistate Retention of Organic Neuromorphic Devices Using Anion‐Excessive Gel Electrolyte

open access: yesAdvanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
Anion‐excessive gel‐based organic synaptic transistors (AEG‐OSTs) that can maintain electrical neutrality are developed to enhance synaptic plasticity and multistate retention. Key improvement is attributed to the maintenance of electrical neutrality in the electrolyte even after electrochemical doping, which reduces the Coulombic force acting on ...

Frontiers in the Management of Orthopaedic Periprosthetic Joint Infection

open access: yesJournal of Orthopaedic Research, Volume 44, Issue 2, February 2026.
ABSTRACT Periprosthetic joint infection (PJI) is a devastating complication of total joint arthroplasty (TJA), one of the most frequently performed surgical procedures worldwide. Management of acute PJI commonly involves debridement, antibiotics, and implant retention (DAIR), though failure rates remain high due to antibiotic‐tolerant biofilms. Chronic

Fabrication of High‐Performance rGO/Cu Composites via Arc Induction Melting: A Comprehensive Study on Microstructure, Tribological and Electrical Properties

open access: yesAdvanced Engineering Materials, Volume 28, Issue 2, 21 January 2026.
Cu composites containing 0.5–1 wt% rGO were produced via Arc Induction Melting, achieving grain refinement and Hall–Petch, Orowan and load‐transfer strengthening that increased hardness from 65 to 225HV30.rGO‐derived tribofilms cut wear by 78% and friction by over 60.

Proximity to seabird colonies and water availability shape moss distributions in Antarctica

open access: yesEcography, Volume 2026, Issue 1, January 2026.
Understanding species distributions across Antarctica is crucial for biodiversity conservation under climate change, but continental‐scale analyses of key terrestrial species remain scarce. Here, we modelled distributions of 28 moss species across Antarctica using log‐Gaussian Cox process models and environmental covariates including topographic ...

XAI‐Supported Dynamics of Civil Aircraft Trajectory: Energy Conservation in Point Mass Modeling With Comparative Analysis

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
Precise aircraft trajectory prediction is a critical issue in civil aviation. Traditional dynamics analysis using the classical point mass model often encounters deviations due to inaccuracies in aircraft mass estimation, which can ultimately undermine the validity of the energy conservation equation.

The effect of temperature during the hydrocracking of low-density polyethylene using a Ni-Cu/HZSM-5 catalyst

open access: yesInternational Journal of Renewable Energy Development
LDPE plastics contributed 20-30% of the plastics use. Due to its non-biodegradable properties, plastic waste management is crucial. In the other hand, the LDPE plastics provide potential and benefits in the exploration of energy resources; they could be ...
