JUNTO A LA APARICIÓN DE LA PRESENTE EDICIÓN, LA REVISTA MADERAS-CIENCIA Y TECNOLOGÍA, CUMPLE EL DÉCIMO ANIVERSARIO DE SU SELECCIÓN EN SCIELO-CHILE. ESTE HITO DEL AÑO 2005, MARCÓ NOTABLEMENTE LA NE-CESIDAD DE UN CAMBIO EN LA GESTIÓN DE MANUSCRITOS Y DE PROFESIONALIZACIÓN DE LA PRODUCCIÓN EDITORIAL DE LA REVISTA. EL PRIMER CAMBIO FUE INCORPORAR ADEMÁS DE LA PRODUCCIÓN EN PAPEL IMPRESO A LA PUBLICACIÓN ONLINE EN LA COLECCIÓN SCIELO. ESTE AVANCE IMPLICÓ LA INCORPORACIÓN DE UN PROFESIONAL DEDICADO A LA PRODUCCIÓN EDITORIAL DE LA REVISTA PARA CUMPLIR CON LOS PROTOCOLOS Y REQUISITOS DE LA TECNOLOGÍA REQUERIDA POR SCIELO. LA DIGITALIZACIÓN DE LA REVISTA Y SU VITRINA EN SCIELO FAVORECIÓ EL ACCESO A AUTORES Y LECTORES DE LA REVISTA. RESULTANDO QUE INMEDIATAMENTE DESPUÉS, LA REVISTA FUERA SELECCIONADA E INCORPORADA A REDALYC Y SCOPUS. EN ADICIÓN, EL FLUJO DE MANUSCRITOS SOMETIDOS A LA REVISTA SE INCREMENTÓ EN UN 50% EN LOS DOS PRIMEROS AÑOS EN SCIELO, LA TASA DE RECHAZO TAMBIÉN SE DUPLICÓ Y LA PRODUCCIÓN EDITORIAL AUMENTO EN UN 33 %, PASANDO A PRODUCIR TRES NÚMEROS ANUALES DE MANERA REGULAR Y A TIEMPO CON UN INCREMENTO DE 60% EN ARTÍCULOS CIENTÍFICOS PUBLICADOS.

CUANDO EN JUNIO DEL AÑO 2001, NOS ENCOMENDARON LA MISIÓN DE DIRIGIR LA REVISTA MADERAS. CIENCIA Y TECNOLOGÍA (MCT), COMENZAMOS A IMAGINAR UNA REVISTA DE CARÁCTER CIENTÍFICO QUE CONTRIBUYERA A MOSTRAR A LA SOCIEDAD UNA VISIÓN ORIGINAL DEL CULTIVO DE LAS CIENCIAS DE LA MADERA.

MICROWAVE PRETREATMENT (MWP) HAS EMERGED AS A PROMISING STRATEGY TO ENHANCE THE PYROLYSIS OF LIGNOCELLULOSIC BIOMASS DUE TO ITS RAPID, VOLUMETRIC, AND SELECTIVE HEATING. BY DISRUPTING THE RECALCITRANT STRUCTURE OF CELLULOSE, HEMICELLULOSE, AND LIGNIN, MWP IMPROVES BIOMASS DECONSTRUCTION, INCREASES CARBOHYDRATE ACCESSIBILITY, AND ENHANCES YIELDS OF BIO-OIL, SYNGAS, AND BIOCHAR. WHEN COMBINED WITH COMPLEMENTARY PRETREATMENTS?SUCH AS ALKALI, ACID, HYDROTHERMAL, ULTRASONIC, OR IONIC-LIQUID METHODS?MWP FURTHER REDUCES ACTIVATION ENERGIES, FACILITATING MORE EFFICIENT SACCHARIFICATION AND THERMAL CONVERSION. THIS REVIEW SYSTEMATICALLY EVALUATES SCIENTIFIC PROGRESS IN THIS FIELD THROUGH BIBLIOMETRIC ANALYSIS, MAPPING RESEARCH TRENDS, EVOLUTION, AND COLLABORATIVE NETWORKS. KEY RESEARCH QUESTIONS ARE ADDRESSED REGARDING THE TECHNICAL ADVANTAGES OF MWP, THE PHYSICOCHEMICAL TRANSFORMATIONS INDUCED IN BIOMASS, AND ASSOCIATED ENVIRONMENTAL BENEFITS. FINDINGS INDICATE THAT MICROWAVE IRRADIATION PROMOTES HEMICELLULOSE DEPOLYMERIZATION, REDUCES CELLULOSE CRYSTALLINITY, AND WEAKENS LIGNIN?CARBOHYDRATE LINKAGES, WHICH FACILITATES SUBSEQUENT THERMAL DECOMPOSITION AND CONTRIBUTES TO IMPROVED PYROLYSIS EFFICIENCY AND PRODUCT QUALITY. FROM AN ENVIRONMENTAL PERSPECTIVE, MWP CONTRIBUTES TO ENERGY SAVINGS, MITIGATES GREENHOUSE GAS EMISSIONS, AND SUPPORTS THE INTEGRATION OF RENEWABLE ELECTRICITY IN BIOMASS CONVERSION.

THE GLOBAL RISE IN THE ELDERLY POPULATION INHERENTLY ESCALATES THE DEMAND FOR HEALTH AND SOCIAL CARE. ENSURING COGNITIVE PERFORMANCE FOR HEALTHY BRAIN AGING PRESENTS SIGNIFICANT CHALLENGES FOR RESEARCHERS AND HEALTH PROFESSIONALS PROMOTING SELF-CARE BEHAVIORS. THIS ARTICLE AIMS TO PROVIDE A COMPREHENSIVE AND CRITICAL ANALYSIS OF THE LATEST RESEARCH ON HEALTHY BRAIN AGING BY EMPLOYING A BIOPSYCHOSOCIAL FRAMEWORK. IT INTEGRATES BIOLOGICAL, PSYCHOLOGICAL, AND SOCIAL DIMENSIONS TO ELUCIDATE THEIR COLLECTIVE INFLUENCE ON COGNITIVE HEALTH IN OLDER ADULTS. METHODOLOGICALLY, THIS ARTICLE PROVIDES A NARRATIVE REVIEW OF THE EXISTING LITERATURE. A DIVERSE ARRAY OF BIBLIOGRAPHIC RESOURCES WAS OBTAINED FROM PROMINENT ELECTRONIC DATABASES, INCLUDING MEDLINE, PUBMED, SCOPUS AND WEB OF SCIENCE, TO ENSURE BROAD COVERAGE OF THE TOPIC. THE SEARCH WAS DESIGNED TO CAPTURE RELEVANT STUDIES PUBLISHED BETWEEN 2010 AND 2025, USING KEY TERMS SUCH AS ?AGING?, ?BIOMARKER?, ?NEURODEGENERATION?, AND ?COGNITIVE PERFORMANCE?. FOLLOWING A RIGOROUS SELECTION PROCESS, TWO FIELD SPECIALISTS EVALUATED A TOTAL OF 106 FULL-TEXT ARTICLES TO IDENTIFY THOSE THAT MET THE ELIGIBILITY CRITERIA, ULTIMATELY YIELDING 70 RELEVANT STUDIES. THE FINDINGS REVEAL IMPORTANT CONNECTIONS BETWEEN PSYCHOSOCIAL AND BIOLOGICAL BIOMARKERS AND BRAIN MORPHOLOGY, HIGHLIGHTING LIFESTYLE FACTORS?SUCH AS DIET, EXERCISE, AND SOCIAL ENGAGEMENT?AS CRUCIAL FOR COGNITIVE HEALTH. THE ARTICLE ALSO UNDERSCORES SPECIFIC BIOMARKERS RELEVANT FOR ASSESSING BRAIN AGE AND THEIR RELATIONSHIP TO NEURODEGENERATIVE DISORDERS. NOTABLY, WHILE BIOLOGICAL MARKERS LIKE A?, TAU, AND ?-SYNUCLEIN (PROTEINS THAT DEFINE THE CORE MOLECULAR PATHOLOGY OF COMMON NEURODEGENERATIVE DISEASES) ARE PRESENT, THEY DO NOT GUARANTEE THE ONSET OF NEURODEGENERATIVE DISEASES; PSYCHOSOCIAL FACTORS PLAY AN ESSENTIAL ROLE IN DETERMINING DISEASE MANIFESTATION.

LITHIUM IRON PHOSPHATE (LFP) IS AN OUTSTANDING CATHODE MATERIAL FOR LITHIUM-ION BATTERIES DUE TO ITS THERMAL STABILITY, SAFETY, AND COST-EFFECTIVENESS. HOWEVER, ITS PRACTICAL APPLICATION IS LIMITED BY THE MATERIAL?S INTRINSICALLY LOW ELECTRONIC CONDUCTIVITY AND LITHIUM-ION DIFFUSION COEFFICIENT, WHICH RESTRICT ITS RATE CAPABILITY. THIS REVIEW COMPREHENSIVELY EXAMINES VARIOUS STRATEGIES DEVELOPED TO ENHANCE THE ELECTROCHEMICAL PERFORMANCE OF LFP, FOCUSING ON BOTH INDIVIDUAL AND COMBINED IMPROVEMENTS IN IONIC AND ELECTRONIC CONDUCTIVITIES. WE ANALYZE THE IMPACT OF PARTICLE SIZE AND MORPHOLOGY, DOPANTS, CONDUCTIVE ADDITIVES, AND CARBON COATINGS ON THE MATERIAL?S DIFFUSION COEFFICIENT AND ELECTRONIC CONDUCTIVITY, SUPPORTED BY AN EXHAUSTIVE COMPILATION OF DATA FROM LITERATURE. ADDITIONALLY, WE DISCUSS THE POTENTIAL OF THESE STRATEGIES TO SYNERGISTICALLY ENHANCE THE SPECIFIC CAPACITY AND RATE CAPABILITY OF LFP. SPECIAL ATTENTION IS GIVEN TO ADVANCED MANUFACTURING TECHNIQUES AND THE DEVELOPMENT OF NEW MATERIAL ARCHITECTURES AIMED AT OPTIMIZING THE MATERIAL?S KINETIC PROPERTIES AND MINIMIZING INACTIVE COMPONENTS. OUR FINDINGS HIGHLIGHT THE NEED FOR A HOLISTIC APPROACH THAT INTEGRATES THE MOST PROMISING STRATEGIES INTO A UNIFIED LFP STRUCTURE. WE ALSO EMPHASIZE THE IMPORTANCE OF COMPREHENSIVE CHARACTERIZATION, INCLUDING ELECTRONIC CONDUCTIVITY, IONIC DIFFUSIVITY, AND SPECIFIC CAPACITY UNDER VARIOUS CURRENT RATES, TO PROVIDE A MORE COMPLETE UNDERSTANDING OF THE MATERIAL?S BEHAVIOR. THIS REVIEW SERVES AS A GUIDE FOR FUTURE RESEARCH DIRECTIONS, AIMING TO OVERCOME CURRENT LIMITATIONS AND ACHIEVE THE FULL POTENTIAL OF LFP IN HIGH-PERFORMANCE ENERGY STORAGE APPLICATIONS.
