Morphological changes in tetraploid black locust cuttings undergoing adventitious root development in a sand bed.

open access: yes, 2014
a. Softwood cuttings before cutting. b. A white callus appeared at 10 days after cutting. c. A yellow callus appeared and tiny adventitious roots emerged (root primordium) at 15 days after cutting. d. Adventitious root formation and elongation at 20 days

Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

open access: yesCarbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular

The quiescent center and the stem cell niche in the adventitious roots of Arabidopsis thaliana

open access: yes, 2016
Adventitious rooting is essential for the survival of numerous species from vascular cryptogams to monocots, and is required for successful micropropagation. The tissues involved in AR initiation may differ in planta and in in vitro systems. For example,

Synthesis of Chiral‐at‐Sulfur(VI) Sulfonimidamide Brønsted Acids

open access: yesChemistry – A European Journal, EarlyView.
A simple, modular route to chiral‐at‐sulfur(VI) Brønsted acids is described, delivering S‐chiral sulfonimidamides, C2‐symmetric acids, and BINOL‐based hybrid systems through stereospecific reactions of sulfonimidoyl fluorides and chlorides. ABSTRACT Herein, we report an efficient and simple strategy to access diverse chiral‐at‐sulfur(VI) Brønsted acids.

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

A proteomic investigation of forebrain regeneration in the leopard gecko (Eublepharis macularius)

open access: yesDevelopmental Dynamics, EarlyView.
Our investigation reveals ontogenetic, injury‐ and regeneration‐associated proteomic changes in the leopard gecko forebrain. Abstract Background The ability to replace lost or damaged neurons following an injury is termed reactive neurogenesis. Although reactive neurogenesis has been reported in several lizard species, the molecular mechanisms ...

Constructed Red Phosphorus/BiVO4 S‐Scheme Heterojunction for Efficient Photocatalytic Overall Water Splitting

open access: yesEcoEnergy, EarlyView.
An S‐scheme red phosphorus/BiVO4 heterojunction is presented, where red phosphorus served as the water reduction site, and BiVO4 functioned as the water oxidation site. Because it has a built‐in electric field that helps charge transfer and separation, red phosphorus/BiVO4 works very well in the photocatalytic overall water splitting process.

Enhancing Activity of Oxygen Evolution Reaction on Fe/CoOOH/NF Electrocatalysts: Effect of Fe Doping

open access: yesEcoEnergy, EarlyView.
ABSTRACT Exploring low‐cost and high‐efficiency electrocatalysts for oxygen evolution reaction (OER) is of great significance. In this work, a series of Fex/CoOOH‐y/NF electrocatalysts are fabricated by etching Co‐MOFs/NF with Fe(NO3)3 solution. The doping of Fe makes a great contribution to the transformation of CoOx to CoOOH species.

Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.
