The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Development of Modified Zeolites for Methane Separation from Diluted Streams

Inorganics
Methane (CH4) is the second-largest contributor to climate change after carbon dioxide (CO2) and has a global warming potential about 72 times greater than CO2 over a 20-year timescale.

MEM-BRAIN gas separation membranes for zero-emission fossil power plants [PDF]

, 2008
The objective of the "MEM-BRAIN" project is the development and integration of ceramic and polymeric gas separation membranes for zero-emission fossil power plants. This will be achieved using membranes with a high permeability and selectivity for either

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Three-dimensional porous hollow fibre copper electrodes for efficient and high-rate electrochemical carbon dioxide reduction

Nature Communications, 2016
Aqueous phase electrochemical reduction of CO2requires an active electrocatalyst and efficient mass transport. Here, the authors report a hollow fibre copper electrode displaying compact 3D geometry, with a large area, three phase boundary for gas-liquid

Cation-selective layered silicon oxide membranes for power generation

JPhys Energy, 2022
Inorganic two-dimensional membranes offer a new approach to modulating mass transport at the nanoscale. These membranes, which can harness the van der Waals gap as a nanochannel and address persistent challenges in organic membranes, are limited to a few

Thin Inorganic Porous Hollow Fiber Membranes

, 2013
Extensive research has been performed on inorganic hollow fibers by dry–wet spinning of a particle loaded polymer solution, followed by thermal treatment. Several research groups have shown this approach to be feasible for variety of inorganic particles.
