Cellulose Hydrogels by Reversible Ion‐Exchange as Flexible Pressure Sensors
cellulose hydrogels ions exchange orientation pressure sensing
2024/1/23
Inspired by biological camouflage strategy according to the surrounding environment, a facile method to fabricate state‐switchable cellulose hydrogels (fluid, brittle, and rigid hydrogel) driven by Ca...
Epoxidation of Tall Oil Catalyzed by an Ion Exchange Resin under Conventional Heating and Microwave Irradiation
Tall oil fatty acids Conventional Heating Microwave Irradiation
2024/1/10
Tall oil fatty acids (TOFA) are a byproduct from the Kraft pulping process, and they represent a renewable and inexpensive alternative with high potential as a renewable feedstock. Epoxidized TOFA hav...
An improved theory for calculating leaf gas exchange more precisely accounting for small fluxes
gas exchange leaf von Caemmerer and Farquhar (vCF)
2023/12/8
The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for...
Pendent piperidinium-functionalized blend anion exchange membrane for fuel cell application
Anion exchange membrane Blend polymers Polybenzimidazole Piperidinium Inter-chain forces
2023/6/19
Alkaline anion exchange membrane fuel cell has fast cathode reactions and thus allows the use of low cost electrocatalysts. However, its practical application is hindered by the low hydroxide ion cond...
Effect of vapor pressure deficit on gas exchange in wild-type and abscisic acid-insensitive plants
ABA-signaling Drought stress HOS15 OST1 ABI1/2 Protein degradation and stability
2024/2/28
Stomata control the gas exchange of terrestrial plant leaves, and are therefore essential to plant growth and survival. We investigated gas exchange responses to vapor pressure deficit (VPD) in two gr...
New Paper Published in Nature Communications titled, “Exact exchange-correlation potentials from ground-state electron densities”
Published titled Exact potentials electron densities
2019/10/10
The quest for accurate exchange-correlation functionals has long remained a grand challenge in density functional theory (DFT), as it describes the many-electron quantum mechanical behavior through a ...
Separating Standard and Asymmetric Password-Authenticated Key Exchange
PAKE Password-Authenticated Key Exchange
2019/9/23
Password-Authenticated Key Exchange (PAKE) is a method to establish cryptographic keys between two users sharing a low-entropy password. In its asymmetric version, one of the users acts as a server an...
Modifying The Tropical Version of Stickel’s Key Exchange Protocol
Stickel’s protocol Tropical Algebra Cryptography
2019/8/2
A tropical version of Stickel’s key exchange protocol was suggested by Grigoriev and Sphilrain [2] and successfully attacked by Kotov and Ushakov [5]. We suggest some modifications of this scheme that...
Prototyping post-quantum and hybrid key exchange and authentication in TLS and SSH
post-quantum cryptography TLS SSH
2019/7/25
Once algorithms for quantum-resistant key exchange and digital signature schemes are selected by standards bodies, adoption of post-quantum cryptography will depend on progress in integrating those al...
