MXenes as a Versatile Platform for High‐Energy‐Density Asymmetric Supercapacitors

Carbon Energy, EarlyView.
MXenes with high conductivity and tunable surface chemistry are reviewed as advanced electrodes for asymmetric supercapacitors. MAX‐phase synthesis, surface and interlayer engineering, defect modulation, and composite designs are discussed, highlighting enhanced ion transport, pseudocapacitance, energy density, cycling stability, and sustainable routes

Lectures on Supersingular K3 Surfaces and the Crystalline Torelli Theorem

, 2016
We survey crystalline cohomology, crystals, and formal group laws with an emphasis on geometry. We apply these concepts to K3 surfaces, and especially to supersingular K3 surfaces.

Tyurin degenerations of K3 surfaces

This thesis focuses on Type II degenerations of K3 surfaces of degrees 2 and 4.In Chapter 1 we lay out the necessary background material required in this work, beginning with the fundamentals of K3 surface theory and their moduli spaces.

CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

Carbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

Higher-dimensional analogues of K3 surfaces

, 2012
A K\"ahler manifold $X$ is {\it hyperk\"ahler} (HK) if it is simply connected and it carries a holomorphic {\bf symplectic} form whose cohomology class spans $H^{2,0}(X)$. A HK manifold of dimension $2$ is a $K3$ surface.

Constructing Enzyme‐Inspired Multisite Synergistic Catalyst for Promoting CO2 Electroreduction to Ethylene at pH Universal Condition

Carbon Energy, EarlyView.
A rational synthesis strategy was developed to construct enzyme‐inspired Cu‐AM catalysts with well‐defined multisite architectures. This catalytic system enables highly selective electrochemical CO2 reduction to C2H4 under pH‐universal conditions, delivering exceptional Faradaic efficiencies across acidic, neutral, and alkaline electrolytes.

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

Carbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Dinuclear Copper(I) Complexes Featuring Metal–Metal Interactions and a μ2‐Bridging Phosphane With Additional Olefinic Binding Sites

Chemistry – A European Journal, EarlyView.
A Cu2P triangle captured in a tetrapodal phosphane tris(olefin) ligand, where all binding forces are weak apart from the Cu─P interaction. ABSTRACT The molecule Ptrop3 contains in each trop unit (trop = dibenzo[a,d]cyclohepten‐5‐yl) a rigid central seven‐membered ring with an olefinic binding site making Ptrop3 potentially a tetradentate ligand ...
