Status and future of recombinant adeno‐associated virus vector manufacturing

Biotechnology Progress, EarlyView.
Abstract Sixty years of adeno‐associated virus (AAV) research illustrates a trajectory marked by basic science exploration, iterative innovation, persistent challenges, a number of clinical setbacks, as well as commercial therapeutic triumphs. This continual evolution has led to recombinant AAV (rAAV) becoming a cornerstone of modern gene therapy ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Regulatory Convergence and Divergence in ESG Reporting in the Indo‐Pacific Region

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Environmental, social, and governance (ESG) reporting has evolved significantly globally over the past few decades. Many countries are now signatories to international agreements such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement, with increasing commitments to emissions reduction targets and the

Evaluation procedure for radioactive waste treatment processes [PDF]

, 1979
An aspect of the Los Alamos Scientific Laboratory's nuclear waste management R and D programs has been to develop an evaluation procedure for radioactive waste treatment processes. This report describes the process evaluation method. Process worth is expressed as a numerical index called the Figure-of-Merit (FOM), which is computed using a hierarchial,

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

Deep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.
